The month of birth,age,gender,and ethnicity was recorded. Differences between number of births observed and expected in the winter months(October through February) and non-winter mo(March through September) were analyzed with the χ2 test. Detailed temporal variation was mathematically assessed using cosinor analysis.RESULTS There were 7792 OA patients and 60 DDH patients who underwent total hip arthroplasty. There were more births than expected in the winter months for both the DDH(P < 0.0001) and OA(P = 0.0052) groups. Cosinor analyses demonstrated a peak date of birth on 1st October. CONCLUSION These data demonstrate an increased prevalence of DDH and OA in those patients born in winter.展开更多

Persi...Developmental dysplasia of the hip(DDH) describes the spectrum of structural abnormalities that involve the growing hip. Early diagnosis and treatment is critical to provide the best possible functional outcome. Persistence of hip dysplasia into adolescence and adulthood may result in abnormal gait, decreased strength and increased rate of degenerative hip and knee joint disease. Despite efforts to recognize and treat all cases of DDH soon after birth, diagnosis is delayed in some children, and outcomes deteriorate with increasing delay of presentation. Different screening programs for DDH were implicated. The suspicion is raised based on a physical examination soon after birth. Radiography and ultrasonography are used to confirm the diagnosis. The role of other imaging modalities, such as magnetic resonance imaging, is still undetermined; however, extensive research is underway on this subject. Treatment depends on the age of the patient and the reducibility of the hip joint. At an early age and up to 6 mo, the main treatment is an abduction brace like the Pavlik harness. If this fails, closed reduction and spica casting is usually done. After the age of 18 mo, treatment usually consists of open reduction and hip reconstruction surgery. Various treatment protocols have been proposed. We summarize the current practice for detection and treatment of DDH, emphasizing updates in screening and treatment during the last two decades.展开更多

Clinical diagnostic tests complement ultrasound imaging in allowing diagnosis, classification and monitoring of this condition. Classification systems relate to the alpha and beta angles in addition to the dynamic coverage index(DCI). Screening programmes for DDH show considerable geographic variation; certain risk factors have been identified which necessitate ultrasound assessment of the newborn. The treatment of DDH has undergone significant evolution, but the current gold standard is still the Pavlik harness. Duration of Pavlik harness treatment has been reported to range from 3 to 9.3 mo. The beta angle, DCI and the superior/lateral femoral head displacement can be assessed via ultrasound to estimate the likelihood of success. Success rates of between 7% and 99% have been reported when using the harness to treat DDH. Avascular necrosis remains the most devastating complication of harness usage with a reported rate of between 0% and 28%. Alternative non-surgical treatment methods used for DDH include devices proposed by LeD amany, Frejka, Lorenz and Ortolani. The Rosen splint and Wagner stocking have also been used for DDH treatment. Surgical treatment for DDH comprises open reduction alongside a combination of femoral or pelvic osteotomies. Femoral osteotomies are carried out in cases of excessive anteversion or valgus deformity of the femoral neck. The two principal pelvic osteotomies most commonly performed are the Salter osteotomy and Pemberton acetabuloplasty. Serious surgical complications include epiphyseal damage, sciatic nerve damage and femoral neck fracture.展开更多

The complex femoral and acetabular anatomy makes standard reconstruction technically challenging. Acetabular coverage can be improved by medialization of the component or augmentation of the deficient areas with bone graft. Femoral shortening osteotomies are considered in cases of severe dysplasia and frankly dislocated hips. Each patient's unique anatomy dictates what options of reconstruction are available. The functional outcomes of THA in DDH are generally excellent, though higher rates of mechanical failure have been reported in this group. This article reviews the anatomy, classification, technical considerations, and outcomes of THA in patients with DDH.展开更多

Methods: A systematic review was performed for all the published articles in the English language literature on DDH in Saudi Arabia. Data sources were PubMed Medline (1980-2018) (http://www.ncbi.nlm.nih.gov/pubmed/), Ovid Medline (1980-2018), EMBASE MEDLINE (1980 to May 2018), EMBASE (1991 to May 2018), the Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, the Science Citation Index (1966 to May 2018), published data from the Saudi Medical Journal (1985-2018) and Annals of Saudi Medicine (1985-2018). The author independently reviewed articles and abstracted the data. The key words used were Saudi Arabia developmental dysplasia of the hip ORDDH, congenital hip dislocation or congenital subluxation of the hip, and congenital dysplasia of the hip. Results: The authors identified 18 potentially relevant articles published in the last 38 years, and 10 met the inclusion criteria. The 10 studies analyzed included 2037 studies of infants diagnosed with DDH;and they gave an average incidence of 10.46/1000. Two studies (303 subjects) did not report the affected gender;in the remaining 338 were boys and 1396 were girls and one study did not report the side of affection. The majority presented after 12 months of age. The right side was affected in 532 (27.2%) affected, 734 (37.6%) were left side and 687 (35.2%) infants were affected bilaterally. Consanguinity, breech presentation, and family history were found to be the risk factors in 32.9%, 17.3%, and 23.6% of the patients, respectively. Conclusions: There is paucity of available literature on DDH in Saudi Arabia. New strategies have to be developed that include mandatory screening programs in all hospitals (private and public) so that more children can be treated by nonsurgical methods.展开更多

Newborns were selected from public and private hospitals in Celaya, Guanajuato. Parents were asked to sign informed consent. Clinical maneuvers were applied for diagnosis of developmental dysplasia of the hip, on three consecutive occasions, two by the same investigator and the third by a different observer: Ortolani, Barlow, Piston, Galeazzi, Peter Baden, the comparative sound transmission test, and comparative sound transmission with extension/flexion test were applied. The diagnosis was confirmed with ultrasound of hip, technique Graf, I healthy hip, II functionally immature, III subluxation, and IV dislocation. Sample size was 8 affected hips and 56 healthy hips. Kappa for intra observer and inter observer reliability were measured;the validity was measured by sensitivity, specificity, positive and negative predictive values, using the ultrasound diagnosis as the gold standard. The sample consisted of 78 neonates hips with female’s predominance. With comparative sound transmission test was obtained Kappa intra observer 0.80, Kappa inter observer 0.93, sensitivity 45.45%, specificity 96.27%, positive predictive value 66.67% and negative predictive value 91.49%;with comparative sound transmission with extension/flexion, was 0.83, 0.92, 72.73%, 95.52%, 72.73%, and 95.52%, respectively. The tests compared the sound transmission help better diagnose developmental dysplasia disease of the hip.展开更多
Background/Aim: The present study was directed to investigate the accuracy of ultrasound (USG) in early detection of developmental dysplasia of the hip (DDH) to prevent permanent complications. Material & Methods:...Background/Aim: The present study was directed to investigate the accuracy of ultrasound (USG) in early detection of developmental dysplasia of the hip (DDH) to prevent permanent complications. Material & Methods: A total of 276 infants was investigated;their ages range from 1 - 6 months. Patients referred from the clinic based on clinical assessment (mainly Barlo & Ortolani maneuvers). Then the patient’s hips were examined by expert radiologists in USG scan. After that, dynamic (coronal and transverse) & static ultrasound views evaluated by the same radiologist using Graf’s criteria. Infants with abnormal ultrasound findings suggestive of DDH were followed up after 4 - 6 weeks by the same investigator to monitor the progress. At the same time, the patient referred to a specialist for conservative management from the first positive findings. Results: Among the 276 referred patients, infants with normal stable hips (Graf Type I and Type II a+) were 221 (80%), 155 of them were female and 66 male infants. Infants with unstable hips based on Graf’s criteria (Type II a-, II b, II c and Type III a) were 55 (20%). Out of 55 with abnormal findings, the affected hips on both sides, right and left were: 5 cases (1.8%), 7 (2.5%) and 43 hips (15.5%) consecutively. Out of 55 infants affected;3 referred to tertiary centers for further surgical management while 52 managed conservatively. Conclusion: Delayed treatment rates of DDH and complications could be reduced by the usage of the USG after the first month of life. In addition to physical assessment, USG for high-risk infants will provide more accurate diagnosis and minimize complications.展开更多

Therefore, early detection and management is crucial to improve the outcome and minimise the risk of osteoarthritis in later life. Hip ultrasound is used to evaluate DDH based on Graf classification. Graf score is a widely used ultrasound grading score to evaluate DDH in infants. There is conflicting evidence regarding the management of the developmentally immature Graf type IIa hip. Some physicians adopt watchful waiting for natural maturation of hips while other early treatment. This article will provide an evidence-based review on the management modalities of the Graf type IIa hip.展开更多

Autograft concern is further supported by authors who suggest the routine use of internal fixation. Problems such as graft extrusion, rotation and absorption, leading to loss of acetabular correction, were often noted in cases previously treated at our National Hospital for Pediatrics. This retrospective study reviewed the radiographic results of this treatment protocol in 106 hips developmental dislocated hips which met our inclusion criteria. The efficacy of this method to achieve and maintain a well covered and stable hip was the main objective of the study. Methods: This retrospective study reviewed the radiographs of 106 hips presenting with developmental dislocation which were treated by modified Salter’s innomiate osteotomy and using a fibular allograft as the interposition material. Dislocations of the hip were graded using the T?nnis system. Measurement of the acetabular index (AI) was the main variable. The minimum follow up period was 2 years. Possible complications such as loss of acetabular correction, hip redislocation, graft extrusion or resorption, the need for osteotomy internal fixation, delayed or non union, infection or avascular necrosis (AVN) were documented in this series. Results: Between January 2004 and December 2008, 106 surgeries were performed in 95 patients. Sixty-three (86.3%) of the patients were girls and ten (13.7%) were boys, thirteen patients (13.7%) were between twelve and eighteen months old at the time of the operation, the remaining eighty-two (86.3%) patients being between eighteen and thirty-six months old, with the mean age of 22.6 months at the time of surgery. There were eleven (11.6%) patients who had bilateral dislocation. Eighty-four (88.4%) patients were affected unilaterally. The right hip was involved in seventeen (17.9%) and the left hip in sixty-seven (70.5%) cases. T?nnis system Type 3 was in 34 hip (32.1%), and Type 4 was in 72 hip (67.9%). All patients combined open reduction and modified Salter’s innomiate osteotomy, inserting a fibular allograft as the interposition material. Acetabular index was improved, preoperation was 42.95°, and latest follow-up 19.15°, concentrical acetabulum 93.7%. All of the fibulat allografts were completely incorporated mean 14 weeks (range, 12 weeks - 17 weeks) post-surgery. There were five (4.7%) redislocation and subluxation, three AVN (2.8%) and five (4.7%) coxa magna Without graft infections, none of the osteotomies required internal fixation for stability. Final results: Excellent 70 (66.0%), Good 29 (27.4%), Fair 2 (1.9%), Poor 5 (4.7%). Conclusion: Open reduction and modified Salter’s innomiate osteotomy allow interposition material by fibular allografting with a short operative incision, renders excellent osteotomy stability that eliminates the need for internal fixation. Surgical technique are safe and effective for Children between twelve and thirty-six months old.展开更多

We aimed to determine the prevalence of DDH in Chinese adults. Methods: In this study, we performed a cross-sectional survey of a nationally representative sample of Chinese adults. All participants underwent questionnaire investigation, physical examination, and X-ray examination. Factors associated with DDH were analyzed with logistic regression. Results: We invited 29,180 individuals aged 18 years and over to participate, randomly selected from 18 primary sampling units (street districts in urban areas and townships in rural areas). The survey and examination were completed in 25,767 people (I 0,296 men and 15,471 women). DDH was diagnosed in 391 people, yielding an overall DDH prevalence of 1.52%. Based on this information, we estimate the number of individuals with DDH in China to be approximately 16.05 million. DDH prevalence increased with age (odds ratio = 1.53 [1 .03-2.27], P = 0.036), was significantly higher among women than men (2.07% vs. 0.75%, P 〈 0.001), and was higher among rural residents than urban residents (1.75% vs. 1.29%, P 〈 0.001). Economic development was independently associated with the presence of DDH. There was no evidence of an association between body mass index alone, education~ or current smoking or drinking and risk of DDH (P 〉 0.05). Conclusions: DDH has become an important public health problem. Special attention should be paid to residents with DDH. Screening for DDH should be performed in China.展开更多

It is a common cause of secondary osteoarthritis in young adults and is the underlying diagnosis in up to 48% of patients requiring total hip arthroplasty (THA) for coxarthrosis. The aim of this study was to evaluate efficiency and safety of THA using Zweym(311er hip implant in the treatment of severe osteoarthritis secondary to developmental dysplasia of the hip (DDH) in adults. Methods From January 2000 to February 2008, 35 patients (40 hips) with developmental dysplasia of the hip were included. Five were male and 30 were female, with ages ranging from 26 to 65 years and an average age of 45 years. According to Hartofilakidis classification, there were type I in 5 hips, type II in 20 hips, type III in 15 hips. All the patients were performed the THA using the Zweym011er hip implant. The preoperative average Harris score was 44. The bilateral arthroplasty was performed in 5 patients and the unilateral arthroplasty in 30 patients. The patients mainly suffered from pain and claudication. Clinical and radiological results were analyzed. The Harris score was used for outcome measurement. Results Thirty five patients (40 hips) were followed and the mean follow-up period was 46 months (ranged from 24 months to 96 months). The latest follow-up average Harris score was 88.9 (97.1% of good rate). All the patients were pain-free and there was no sign of infection, aseptic loosening and subsidence. Conclusions In summary, THA using Zweym011er hip implant is a good treatment method for severe osteoarthritis secondary to DDH in adults. The key techniques for the total hip replacement are as follows: good preoperative plan, firmly placing the acetabular component in the true acetabulum, proper preparation of proximal femur, suitable femoral component choosing and improving the techniques of the bone graft.展开更多

文摘BACKGROUND Developmental dysplasia of the hip(DDH)is a common osteoarticular deformity in pediatric orthopedics.A patient with bilateral DDH was diagnosed and treated using our improved technique"(powerful overturning acetabuloplasty)"combined with femoral rotational shortening osteotomy.CASE SUMMARY A 4-year-old girl who was diagnosed with bilateral DDH could not stand normally,and sought surgical treatment to solve the problem of double hip extension and standing.As this child had high dislocation of the hip joint and the acetabular index was high,we changed the traditional acetabuloplasty to"powerful turnover acetabuloplasty"combined with femoral rotation shortening osteotomy.During the short-term postoperative follow-up(1,3,6,9,12,and 15 months),the child had no discomfort in her lower limbs.After the braces and internal fixation plates were removed,formal rehabilitation training was actively carried out.CONCLUSION Our"powerful overturning acetabuloplasty"combined with femoral rotational shortening osteotomy is feasible in the treatment of DDH in children.This technology may be widely used in the clinic.
文摘AIM To determine if there was a seasonal variation in adults undergoing total hip arthroplasty for end stage hip disease due to osteoarthritis(OA) or sequelae of developmental dysplasia of the hip(DDH).METHODS The total hip registry from the author's institution for the years 1969 to 2013 was reviewed. The month of birth,age,gender,and ethnicity was recorded. Differences between number of births observed and expected in the winter months(October through February) and non-winter mo(March through September) were analyzed with the χ2 test. Detailed temporal variation was mathematically assessed using cosinor analysis.RESULTS There were 7792 OA patients and 60 DDH patients who underwent total hip arthroplasty. There were more births than expected in the winter months for both the DDH(P < 0.0001) and OA(P = 0.0052) groups. Cosinor analyses demonstrated a peak date of birth on 1st October. CONCLUSION These data demonstrate an increased prevalence of DDH and OA in those patients born in winter.

文摘Developmental dysplasia of the hip(DDH) describes the spectrum of structural abnormalities that involve the growing hip. Early diagnosis and treatment is critical to provide the best possible functional outcome. Persistence of hip dysplasia into adolescence and adulthood may result in abnormal gait, decreased strength and increased rate of degenerative hip and knee joint disease. Despite efforts to recognize and treat all cases of DDH soon after birth, diagnosis is delayed in some children, and outcomes deteriorate with increasing delay of presentation. Different screening programs for DDH were implicated. The suspicion is raised based on a physical examination soon after birth. Radiography and ultrasonography are used to confirm the diagnosis. The role of other imaging modalities, such as magnetic resonance imaging, is still undetermined; however, extensive research is underway on this subject. Treatment depends on the age of the patient and the reducibility of the hip joint. At an early age and up to 6 mo, the main treatment is an abduction brace like the Pavlik harness. If this fails, closed reduction and spica casting is usually done. After the age of 18 mo, treatment usually consists of open reduction and hip reconstruction surgery. Various treatment protocols have been proposed. We summarize the current practice for detection and treatment of DDH, emphasizing updates in screening and treatment during the last two decades.
文摘Developmental dysplasia of the hip(DDH) denotes a wide spectrum of conditions ranging from subtle acetabular dysplasia to irreducible hip dislocations. Clinical diagnostic tests complement ultrasound imaging in allowing diagnosis, classification and monitoring of this condition. Classification systems relate to the alpha and beta angles in addition to the dynamic coverage index(DCI). Screening programmes for DDH show considerable geographic variation; certain risk factors have been identified which necessitate ultrasound assessment of the newborn. The treatment of DDH has undergone significant evolution, but the current gold standard is still the Pavlik harness. Duration of Pavlik harness treatment has been reported to range from 3 to 9.3 mo. The beta angle, DCI and the superior/lateral femoral head displacement can be assessed via ultrasound to estimate the likelihood of success. Success rates of between 7% and 99% have been reported when using the harness to treat DDH. Avascular necrosis remains the most devastating complication of harness usage with a reported rate of between 0% and 28%. Alternative non-surgical treatment methods used for DDH include devices proposed by LeD amany, Frejka, Lorenz and Ortolani. The Rosen splint and Wagner stocking have also been used for DDH treatment. Surgical treatment for DDH comprises open reduction alongside a combination of femoral or pelvic osteotomies. Femoral osteotomies are carried out in cases of excessive anteversion or valgus deformity of the femoral neck. The two principal pelvic osteotomies most commonly performed are the Salter osteotomy and Pemberton acetabuloplasty. Serious surgical complications include epiphyseal damage, sciatic nerve damage and femoral neck fracture.
文摘Total hip arthroplasty(THA) in developmental dysplasia of the hip(DDH) presents many challenges to the reconstructive surgeon. The complex femoral and acetabular anatomy makes standard reconstruction technically challenging. Acetabular coverage can be improved by medialization of the component or augmentation of the deficient areas with bone graft. Femoral shortening osteotomies are considered in cases of severe dysplasia and frankly dislocated hips. Each patient's unique anatomy dictates what options of reconstruction are available. The functional outcomes of THA in DDH are generally excellent, though higher rates of mechanical failure have been reported in this group. This article reviews the anatomy, classification, technical considerations, and outcomes of THA in patients with DDH.
文摘The objective of this systematic literature review was to assess the incidence of DDH among the Saudi Arabian population. Methods: A systematic review was performed for all the published articles in the English language literature on DDH in Saudi Arabia. Data sources were PubMed Medline (1980-2018) (http://www.ncbi.nlm.nih.gov/pubmed/), Ovid Medline (1980-2018), EMBASE MEDLINE (1980 to May 2018), EMBASE (1991 to May 2018), the Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, the Science Citation Index (1966 to May 2018), published data from the Saudi Medical Journal (1985-2018) and Annals of Saudi Medicine (1985-2018). The author independently reviewed articles and abstracted the data. The key words used were Saudi Arabia developmental dysplasia of the hip ORDDH, congenital hip dislocation or congenital subluxation of the hip, and congenital dysplasia of the hip. Results: The authors identified 18 potentially relevant articles published in the last 38 years, and 10 met the inclusion criteria. The 10 studies analyzed included 2037 studies of infants diagnosed with DDH;and they gave an average incidence of 10.46/1000. Two studies (303 subjects) did not report the affected gender;in the remaining 338 were boys and 1396 were girls and one study did not report the side of affection. The majority presented after 12 months of age. The right side was affected in 532 (27.2%) affected, 734 (37.6%) were left side and 687 (35.2%) infants were affected bilaterally. Consanguinity, breech presentation, and family history were found to be the risk factors in 32.9%, 17.3%, and 23.6% of the patients, respectively. Conclusions: There is paucity of available literature on DDH in Saudi Arabia. New strategies have to be developed that include mandatory screening programs in all hospitals (private and public) so that more children can be treated by nonsurgical methods.

文摘BACKGROUND A patient with advanced tuberculosis of the hip joint combined with Crowe type IV developmental dysplasia of the hip(DDH)and a drainage sinus is a rare condition.There are no previous reports of this condition,and it is a complex challenge for surgeons to develop a treatment scheme.CASE SUMMARY We report a 73-year-old male patient with severe hip pain and drainage sinus of the left hip for one month.Approximately 40 years ago,a drainage sinus occurred at the lateral left hip was healed at the local hospital with anti-infectious therapy.After the sinus healed,gradual pain occurred in the left hip for 40 years.Approximately one month prior,hip pain was sharply aggravated,and a drainage sinus reoccurred in the left hip.The X-ray and computed tomography examinations showed destruction of the head and neck of the left femur,as well as an acetabular deformity.The results of Mycobacterium tuberculosis antibody and Xpert were positive.Therefore,the patient was diagnosed with advanced TH combined with Crowe type IV DDH.After 22 d of treatment with anti-tuberculosis chemotherapy,the sinus healed,and the patient underwent one-stage total hip arthroplasty(THA)surgery consisting of debridement,osteotomy,and joint replacement.After surgery,the patient received anti-tuberculosis chemotherapy drugs for nine months,with no recurrent infection.After one year of follow-up,the Harris score of the patient increased from 21 pre-THA to 86.CONCLUSION Although drainage sinuses are a contraindication to one-stage THA,one-stage THA is still an effective and safe surgical method after the sinus heals.
文摘The developmental dysplasia of the hip disease is in 1% of newborns, and it is a risk factor for dislocation of the hip;only 1 from 7000 newborns develops dislocation of the hip. Newborns were selected from public and private hospitals in Celaya, Guanajuato. Parents were asked to sign informed consent. Clinical maneuvers were applied for diagnosis of developmental dysplasia of the hip, on three consecutive occasions, two by the same investigator and the third by a different observer: Ortolani, Barlow, Piston, Galeazzi, Peter Baden, the comparative sound transmission test, and comparative sound transmission with extension/flexion test were applied. The diagnosis was confirmed with ultrasound of hip, technique Graf, I healthy hip, II functionally immature, III subluxation, and IV dislocation. Sample size was 8 affected hips and 56 healthy hips. Kappa for intra observer and inter observer reliability were measured;the validity was measured by sensitivity, specificity, positive and negative predictive values, using the ultrasound diagnosis as the gold standard. The sample consisted of 78 neonates hips with female’s predominance. With comparative sound transmission test was obtained Kappa intra observer 0.80, Kappa inter observer 0.93, sensitivity 45.45%, specificity 96.27%, positive predictive value 66.67% and negative predictive value 91.49%;with comparative sound transmission with extension/flexion, was 0.83, 0.92, 72.73%, 95.52%, 72.73%, and 95.52%, respectively. The tests compared the sound transmission help better diagnose developmental dysplasia disease of the hip.
文摘Background/Aim: The present study was directed to investigate the accuracy of ultrasound (USG) in early detection of developmental dysplasia of the hip (DDH) to prevent permanent complications. Material & Methods: A total of 276 infants was investigated;their ages range from 1 - 6 months. Patients referred from the clinic based on clinical assessment (mainly Barlo & Ortolani maneuvers). Then the patient’s hips were examined by expert radiologists in USG scan. After that, dynamic (coronal and transverse) & static ultrasound views evaluated by the same radiologist using Graf’s criteria. Infants with abnormal ultrasound findings suggestive of DDH were followed up after 4 - 6 weeks by the same investigator to monitor the progress. At the same time, the patient referred to a specialist for conservative management from the first positive findings. Results: Among the 276 referred patients, infants with normal stable hips (Graf Type I and Type II a+) were 221 (80%), 155 of them were female and 66 male infants. Infants with unstable hips based on Graf’s criteria (Type II a-, II b, II c and Type III a) were 55 (20%). Out of 55 with abnormal findings, the affected hips on both sides, right and left were: 5 cases (1.8%), 7 (2.5%) and 43 hips (15.5%) consecutively. Out of 55 infants affected;3 referred to tertiary centers for further surgical management while 52 managed conservatively. Conclusion: Delayed treatment rates of DDH and complications could be reduced by the usage of the USG after the first month of life. In addition to physical assessment, USG for high-risk infants will provide more accurate diagnosis and minimize complications.
文摘Developmental Dysplasia of the Hip (DDH) describes a wide range of anatomic abnormalities of the growing hips which might result in permanent abnormal gait. Therefore, early detection and management is crucial to improve the outcome and minimise the risk of osteoarthritis in later life. Hip ultrasound is used to evaluate DDH based on Graf classification. Graf score is a widely used ultrasound grading score to evaluate DDH in infants. There is conflicting evidence regarding the management of the developmentally immature Graf type IIa hip. Some physicians adopt watchful waiting for natural maturation of hips while other early treatment. This article will provide an evidence-based review on the management modalities of the Graf type IIa hip.
文摘Background: Innominate osteotomy procedures have been widely used as an integral component of combined surgery to treat developmental dysplasia of the hip in children. Autograft concern is further supported by authors who suggest the routine use of internal fixation. Problems such as graft extrusion, rotation and absorption, leading to loss of acetabular correction, were often noted in cases previously treated at our National Hospital for Pediatrics. This retrospective study reviewed the radiographic results of this treatment protocol in 106 hips developmental dislocated hips which met our inclusion criteria. The efficacy of this method to achieve and maintain a well covered and stable hip was the main objective of the study. Methods: This retrospective study reviewed the radiographs of 106 hips presenting with developmental dislocation which were treated by modified Salter’s innomiate osteotomy and using a fibular allograft as the interposition material. Dislocations of the hip were graded using the T?nnis system. Measurement of the acetabular index (AI) was the main variable. The minimum follow up period was 2 years. Possible complications such as loss of acetabular correction, hip redislocation, graft extrusion or resorption, the need for osteotomy internal fixation, delayed or non union, infection or avascular necrosis (AVN) were documented in this series. Results: Between January 2004 and December 2008, 106 surgeries were performed in 95 patients. Sixty-three (86.3%) of the patients were girls and ten (13.7%) were boys, thirteen patients (13.7%) were between twelve and eighteen months old at the time of the operation, the remaining eighty-two (86.3%) patients being between eighteen and thirty-six months old, with the mean age of 22.6 months at the time of surgery. There were eleven (11.6%) patients who had bilateral dislocation. Eighty-four (88.4%) patients were affected unilaterally. The right hip was involved in seventeen (17.9%) and the left hip in sixty-seven (70.5%) cases. T?nnis system Type 3 was in 34 hip (32.1%), and Type 4 was in 72 hip (67.9%). All patients combined open reduction and modified Salter’s innomiate osteotomy, inserting a fibular allograft as the interposition material. Acetabular index was improved, preoperation was 42.95°, and latest follow-up 19.15°, concentrical acetabulum 93.7%. All of the fibulat allografts were completely incorporated mean 14 weeks (range, 12 weeks - 17 weeks) post-surgery. There were five (4.7%) redislocation and subluxation, three AVN (2.8%) and five (4.7%) coxa magna Without graft infections, none of the osteotomies required internal fixation for stability. Final results: Excellent 70 (66.0%), Good 29 (27.4%), Fair 2 (1.9%), Poor 5 (4.7%). Conclusion: Open reduction and modified Salter’s innomiate osteotomy allow interposition material by fibular allografting with a short operative incision, renders excellent osteotomy stability that eliminates the need for internal fixation. Surgical technique are safe and effective for Children between twelve and thirty-six months old.
文摘Developmental dysplasia of hip is a disorder of abnormal development of the hip joint resulting early osteoarthritis of the hip. In late stage of disease, total hip arthroplasty is the option to reduce pain. Total hip arthroplasty in development dyplastic hip is a very challenging procedure in view of abnormal anatomy and biomechanic of the hip. A proper pre-operative planning is important of successful surgery. We report a case of a 60-year-old woman with neglected DDH with severe hip pain, who underwent total hip replacement with good result.
文摘Background: The prevalence of developmental dysplasia of the hip (DDH) is unknown in China. We aimed to determine the prevalence of DDH in Chinese adults. Methods: In this study, we performed a cross-sectional survey of a nationally representative sample of Chinese adults. All participants underwent questionnaire investigation, physical examination, and X-ray examination. Factors associated with DDH were analyzed with logistic regression. Results: We invited 29,180 individuals aged 18 years and over to participate, randomly selected from 18 primary sampling units (street districts in urban areas and townships in rural areas). The survey and examination were completed in 25,767 people (I 0,296 men and 15,471 women). DDH was diagnosed in 391 people, yielding an overall DDH prevalence of 1.52%. Based on this information, we estimate the number of individuals with DDH in China to be approximately 16.05 million. DDH prevalence increased with age (odds ratio = 1.53 [1 .03-2.27], P = 0.036), was significantly higher among women than men (2.07% vs. 0.75%, P 〈 0.001), and was higher among rural residents than urban residents (1.75% vs. 1.29%, P 〈 0.001). Economic development was independently associated with the presence of DDH. There was no evidence of an association between body mass index alone, education~ or current smoking or drinking and risk of DDH (P 〉 0.05). Conclusions: DDH has become an important public health problem. Special attention should be paid to residents with DDH. Screening for DDH should be performed in China.
文摘Background Developmental dysplasia encompasses a wide spectrum of hip pathology ranging from a shallow acetabulum to a completely dislocated 'high-riding' hip. It is a common cause of secondary osteoarthritis in young adults and is the underlying diagnosis in up to 48% of patients requiring total hip arthroplasty (THA) for coxarthrosis. The aim of this study was to evaluate efficiency and safety of THA using Zweym(311er hip implant in the treatment of severe osteoarthritis secondary to developmental dysplasia of the hip (DDH) in adults. Methods From January 2000 to February 2008, 35 patients (40 hips) with developmental dysplasia of the hip were included. Five were male and 30 were female, with ages ranging from 26 to 65 years and an average age of 45 years. According to Hartofilakidis classification, there were type I in 5 hips, type II in 20 hips, type III in 15 hips. All the patients were performed the THA using the Zweym011er hip implant. The preoperative average Harris score was 44. The bilateral arthroplasty was performed in 5 patients and the unilateral arthroplasty in 30 patients. The patients mainly suffered from pain and claudication. Clinical and radiological results were analyzed. The Harris score was used for outcome measurement. Results Thirty five patients (40 hips) were followed and the mean follow-up period was 46 months (ranged from 24 months to 96 months). The latest follow-up average Harris score was 88.9 (97.1% of good rate). All the patients were pain-free and there was no sign of infection, aseptic loosening and subsidence. Conclusions In summary, THA using Zweym011er hip implant is a good treatment method for severe osteoarthritis secondary to DDH in adults. The key techniques for the total hip replacement are as follows: good preoperative plan, firmly placing the acetabular component in the true acetabulum, proper preparation of proximal femur, suitable femoral component choosing and improving the techniques of the bone graft.
