Observation of the effects of three methods for reducing perineal swelling in children with developmental hip dislocation

BACKGROUND Developmental dysplasia of the hip is a developmental abnormality of the hip joint that results from hypoplasia during birth and continues to deteriorate after birth.AIM To observe the effects of magnesium sulfate wet compress,iodophor wet compress,and ice compress on reducing postoperative perineal swelling in children with developmental hip dislocation to provide effective nursing interventions in the clinic.METHODS A total of 120 children with hip dislocation after surgery in a third-class A hospital from January 2018 to January 2020 were randomly divided into four groups,the magnesium sulfate wet compress group,iodophor wet compress group,ice compress group and the control group.Data such as height,weight,age,duration of surgery,intraoperative blood loss,postoperative body temperature,swelling duration,pain score,and incidence of blisters were collected and analyzed.RESULTS There were no significant differences in height,weight,age,duration of surgery,intraoperative blood loss,and postoperative body temperature among the four groups of children.Statistical differences were observed between the intervention groups and the control group(P<0.05).CONCLUSION All three methods significantly reduced postoperative perineal swelling in children with developmental hip dislocation,reduced the duration of postoperative perineal swelling,reduced pain,and improved the quality of care.

Treatment of bilateral developmental dysplasia of the hip joint with an improved technique:A case report

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.

Effects of different pelvic osteotomies on acetabular morphology in developmental dysplasia of hip in children

Developmental dysplasia of hip seriously affects the health of children,and pelvic osteotomy is an important part of surgical treatment.Improving the shape of the acetabulum,preventing or delaying the progression of osteoarthritis is the ultimate goal of pelvic osteotomies.Re-directional osteotomies,reshaping osteotomies and salvage osteotomies are the three most common types of pelvic osteotomy.The influence of different pelvic osteotomy on acetabular morphology is different,and the acetabular morphology after osteotomy is closely related to the prognosis of the patients.But there lacks comparison of acetabular morphology between different pelvic osteotomies,on the basis of retrospective analysis and measurable imaging indicators,this study predicted the acetabular shape after developmental dysplasia of the hip pelvic osteotomy in order to help clinicians make reasonable and correct decisions and improve the planning and performance of pelvic osteotomy.

Safety and efficacy of surgical hip dislocation in managing femoral head fractures: A systematic review and meta-analysis

BACKGROUND Femoral head fractures(FHFs)are considered relatively uncommon injuries;however,open reduction and internal fixation is preferred for most displaced fractures.Several surgical approaches had been utilized with controversial results;surgical hip dislocation(SHD)is among these approaches,with the reputation of being demanding and leading to higher complication rates.AIM To determine the efficacy and safety of SHD in managing FHFs by reviewing the results reported in the literature.METHODS Major databases including PubMed,Embase,Web of Science,and Cochrane Central Register of Controlled Trials were searched to identify studies reporting on outcomes of SHD utilized as an approach in treating FHFs.We extracted basic studies data,surgery-related data,functional outcomes,radiological outcomes,and postoperative complications.We calculated the mean differences for continuous data with 95%confidence intervals for each outcome and the odds ratio with 95%confidence intervals for binary outcomes.P<0.05 was considered significant.RESULTS Our search retrieved nine studies meeting our inclusion criteria,with a total of 129 FHFs.The results of our analysis revealed that the average operation time was 123.74 min,while the average blood loss was 491.89 mL.After an average followup of 38.4 mo,a satisfactory clinical outcome was achieved in 85%of patients,ranged from 30%to 86%,with avascular necrosis,heterotopic ossification,and osteoarthritis being the most common complications occurring at an incidence of 12%,25%,and 16%,respectively.Trochanteric flip osteotomy nonunion and trochanteric bursitis as a unique complication of SHD occurred at an incidence of 3.4%and 3.8%,respectively.CONCLUSION The integration of SHD approach for dealing with FHFs offered acceptable functional and radiological outcomes with a wide range of safety in regards to the hip joint vascularity and the development of avascular necrosis,the formation of heterotopic ossification,and the development of posttraumatic osteoarthritis;however,it still carries its unique risk of trochanteric flip osteotomy nonunion and persistent lateral thigh pain.

Corrections in alpha angle following two different operative approaches for CAM-type femoral acetabular impingement-Ganz surgical hip dislocation vs anterior mini-open

BACKGROUND Femoroacetabular impingement(FAI)is a predisposing factor for secondary osteoarthritis of the hip joint.The two extensively described impingement mechanisms of FAI are CAM and Pincer-type.Initially managed conservatively,operative intervention should be offered to the persistently symptomatic patient.The measurement of the alpha angle is considered a standard method of assessing the severity of pathology in Cam-type FAI on pre-operative plain radiographs.The radiological correction of the alpha angle has not been previously compared between different surgical approaches.We hypothesize that there is no difference in alpha angle correction between Ganz surgical hip dislocation and the anterior mini-open approach.AIM To compare the magnitude of alpha angle correction achieved by using the Ganz surgical hip dislocation and the anterior mini-open approach.METHODS This is a retrospective study assessing seventy-nine patients identified in a 5-year period.These patients had preoperative radiographic evidence of FAI and underwent surgery by a single surgeon at our institution,a tertiary care center.Patients with missing radiographic documentation,radiographs with insufficient quality which then precluded accurate measurement of the angleα,a diagnosed congenital condition,isolated type II pathology(Pincer),and history of prior surgery were excluded from the study.Either the Ganz surgical hip dislocation or the anterior mini open approach was used.Postoperative radiographic evaluation of the alpha angle between the two surgical methods was done and corrected for age and gender using two-sample t-tests and Chi-square analyses.RESULTS A total of 79 patients met the inclusion and exclusion criteria.Forty-seven males(mean age of 35.3,range 16-53)and 32 females(mean age 36.7,range 16-60)were enrolled.Forty-seven patients underwent the anterior mini-open approach,and 32 underwent the Ganz surgical hip dislocation.There were no significant differences in age between the two surgical groups or in pre-and post-operative alpha angles based on patient gender.The mean pre-operative alpha angle for the Ganz surgical hip dislocation group was 88.0 degrees(SD 12.3)and 99.4 degrees(SD 7.2)for the anterior mini-open group.Mean post-operative angles were 49.9 degrees(SD 4.3)for the Ganz surgical hip dislocation and 43.8(SD 4.3)degrees for the anterior mini-open group.There was a statistically significant difference in patient’s pre-operative and post-operative angles(P=0.000)with both surgical approaches.CONCLUSION Statistically significant decreases in alpha angle were noted for both surgical techniques,with larger decreases seen in the anterior mini-open group.

Combined bilateral asymmetric hip dislocation and anterior shoulder dislocation

BACKGROUND:Traumatic bilateral hip dislocation is a rare condition.Anterior shoulder dislocation combined with this condition is even a rare occurrence.A 57-year-old man had bilateral asymmetric hip dislocation with a posterior wall fracture of the left acetabulum associated with right shoulder anterior dislocation caused by falling down from a cherry tree.Traumatic hip dislocation and anterior shoulder dislocation represent a true orthopedic emergency.METHODS:Closed reduction was performed immediately for three of the dislocated joints.Posterior wall fracture of the left acetabulum was treated with open reduction and internal fixation by screws.Because of the severity of associated complications like aseptic necrosis or posttraumatic osteoarthritis,efforts were made to ensure prompt diagnosis,therapy and prognosis.RESULTS:The patient was successfully treated by open reduction and internal fixation of the left acetabulum,and discharged from the hospital.CONCLUSION:Traumatic asymmetric hip dislocation and anterior shoulder dislocation are an orthopedic emergency and early diagnosis with immediate reduction of the dislocation is the key determinants of excellent result of treatment.

Innate Immunity in the Development of Connective Tissue Dysplasia: Pilot Study in Children with Congenital Hip Dislocation

Introduction: Observing and treatment of hip dysplasia in children have always been in the sphere of interest of modern molecular medicine. The role of molecular factors in the formation of connective tissue dysplasia in children is considered crucial for such multisystem disorders, and connective tissue dysplasia progressing involves immune system parameters and biochemical markers. The aim of this work was to establish the relationship between immune status indicators and biochemical markers of connective tissue using bioinformatics and modeling methods. Materials and Methods: 27 patients with congenital hip dislocation, admitted to the University Clinic of Privolzhsky Research Medical University, Department of children orthopedics for surgical treatment, were examined. Determination of 10 blood parameters was conducted by modern biochemical and immunological methods. Statistica 12.0 software from StatSoft was used for statistical data processing. Methods of nonparametric statistics were used since the samples in the control group partially follow the normal distribution. Correlation methods and regression modeling methods were used to evaluate the relationship of indicators. Results and Conclusion: In our investigation we have shown the presence of statistical and mathematical interactions between the parameters of innate immunity and indicators of connective tissue metabolism. The leading role of the immune system in the development of pathologies associated with connective tissue dysplasia is assumed. In further investigations it is necessary to clarify the role hypoxia in HIF-1 stimulated control of skeletal dysplasia, collagen modification, connective tissue dysplasia development.

Closed reduction of hip dislocation associated with ipsilateral lower extremity fractures:A case report and review of the literature

BACKGROUND Traumatic hip dislocation usually occurs following high-velocity trauma.It is imperative that the dislocation be reduced in a timely manner,especially in a closed manner,as an orthopedic emergency.However,closed reduction can hardly be achieved in patients who also have ipsilateral lower extremity fractures.Herein,we focus on hip dislocation associated with ipsilateral lower extremity fractures,excluding intracapsular fractures(femoral head and neck fractures),present an early closed hip joint reduction method for this injury pattern,and review the literature to discuss the appropriate closed reduction technique for this rare injury pattern.CASE SUMMARY We report a case of a 37-year-old male who sustained a left acetabular posterior wall fracture,an ipsilateral comminuted subtrochanteric fracture and dislocation of the hip.The hip dislocation was reduced urgently in a closed manner using the joy-stick technique with a T-shaped Schanz screw.The fractures were reduced and fixed as a 2nd-stage surgery procedure.At the 17-month postoperative follow-up,the patient had full range of motion of the affected hip.CONCLUSION Closed reduction of a hip dislocation associated with ipsilateral lower extremity fractures is rarely achieved by regular maneuvers.Attempts at closed reduction,by means of indirectly controlling the proximal fracture fragment or reconstructing the femoral leverage rapidly with the aid of various external reduction apparatuses,were shown to be effective in some scenarios.Mandatory open reduction is indicated in cases of failed closed reduction,particularly in irreducible dislocations.

Irreducible Posterior Hip Dislocation with Associated Isolated Comminuted Greater Trochanter Avulsion Fracture Treated with Universal Locking Trochanteric Stabilization Plate: A Rare Combination of Hip Injury

Posterior hip dislocation with greater trochanter fracture is an uncommon injury pattern in the acute trauma patient. Frequently associated injury includes a combination of hip dislocation with posterior wall of acetabulum, head of femur fracture, intertrochanteric fracture and even the most severe type of combined acetabular fracture. We report a 42-year-old man post traumatic bilateral hip injuries with irreducible posterior hip dislocation and associated isolated greater trochanteric fracture successfully managed with open reduction and fixation of greater trochanter with universal locking trochanteric stabilization plate.

Total hip arthroplasty in developmental dysplasia of the hip: Review of anatomy, techniques and outcomes

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.

Application of spiral CT three dimentional reconstruction on developmental dysplasis of the hip in children

Objective To evaluate the value of surface shaded reconstruction (SSD) of CT scanning on developmental dysplasia of the hip (DDK). Methods Unilateral DDH in 39 cases was examined with Picker 2000S spiral CT to perform SSD of the affected pelvis. All patients were females with the age ranging from 3.5 to 8 years old ( average 4.25 years). Of 39 cases, 22 cases were complete dislocation the hip, 17 cases were subluxation of the hip. The measurement of SSD included of the depth and surface area of normal and affected acetabulum; the distances from the lowest point of the bottom of the acetabulum (O point) to the anterior end (A point) of the lateral margin of anterior acetabular column (OA), the middle point (point) of the acetabular roof (OB) and the posterior end (C point) of lateral margin of the posterior acetabular column (OC). Results In normal hip, the medial and lateral margin of the acetabular roof was overlapping, and in DDH, a bony defect was found in the lateral acetabular margin in

Asymmetrical traumatic bilateral hip dislocations with hemodynamic instability and an unstable pelvic ring: Case report and review of literature

Simultaneous anterior and posterior traumatic dislocations of both hips are very rare. Only 33 cases have been previously reported in the English language literature. Although they were all due to high-energy injuries, they were hemodynamically stable and had a stable pelvic ring. We report a unique case of asymmetrical hip dislocations with an unstable pelvic ring and hemodynamic instability. A 40-year-old man was injured in a high-energy motor vehicle accident. He was hemodynamically unstable when he presented in the emergency department. Radiolographs showed asymmetrical dislocations of both hips with an unstable pelvic ring. Under general anesthesia, he had closed reduction of the dislocations of both hips, followed by temporary stabilization with an external fixator. Transcatheter arterial embolization was performed to stop active pelvic bleeding. Delayed open reduction and internal fixation was performed 12 d later with anterior and posterior plates. The patient recovered well with an uneventful post-operative course. Asymmetrical bilateral hip dislocations with pelvic ring instability caused by trauma, as presented in this case, is very rare and potentially life threatening. Prompt treatment can give a good outcome.

One-stage total hip arthroplasty for advanced hip tuberculosis combined with developmental dysplasia of the hip:A case report

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.

Neglected traumatic hip dislocation: Influence of the increased intracapsular pressure

AIM To investigate that the increased intracapsular pressure, during the delay period, can interrupt the blood flow to the femoral head.METHODS An observational retrospective study included a group of 17 patients with traumatic hip dislocation, their ages at time of injury averaged 26(range from 3 to 70) years. Outcomes were assessed clinically and radiographically at a period averaged 11.5(range from 4 to 20) years.RESULTS Minor trauma caused dislocation in seven and severe trauma in ten patients. All dislocations were posterior, six isolated dislocation and 11 were associated with other injuries. The negligence period averaged 2.5(ranged from 1 to 4) d. At the latest visit, the radiography revealed normal hip in 11 and avascular necrosis(AVN) in six patients. Clinically, eight patients were rated as excellent, three good, three fair and three poor.CONCLUSION We believe the factors that contribute to increased intracapsular pressure also increase the influence of delayed reduction toward the development of AVN.

Seasonal variation in adult hip disease secondary to osteoarthritis and developmental dysplasia of the hip

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.

Diagnosis of Developmental Dysplasia of the Hip Using Sound Transmission in Neonates

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.

Role of Ultrasound in Evaluation of Developmental Dysplasia of the Hip in Infants

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.

Profile of Traumatic Hip Dislocations in a West African Teaching Hospital

Purpose: Traumatic hip dislocations (THD) are rarely reported from developing countries. The aim of the current study is to describe the trauma, the presentation, the treatment and the outcome patterns of THD received in the trauma unit of an emergency department (ED) in west Africa. Patients and Methods: A retrospective ongoing study from 2008 to 2014 was performed at the ED. All patients over 15 years with an unreduced THD and an anteroposterior pelvic radiograph were studied. Data were collected and analyzed by means of a statistical software. Results: A total of 50 THD were included in the study. We found an average of seven dislocations per year with a mean age of 36 years mainly males (n = 37). Road traffic accidents by motorcycle (n = 20) were the common circumstance of trauma. Forty-five extra-pelvic THD were diagnosed. According to the Bigelow classification, THD were classified posterior (n = 33), anterior (n = 10) and irregular (n = 2). Associated acetabular fractures (n = 36), ipsilateral lower limb fractures (n = 10) and sciatic nerve palsy (n = 2) were also found. The THD cases were treated by closed reduction (n = 34), open reduction (n = 6) and Girdlestone procedure (n = 1). The outcome after 16 months showed 21 good and excellent functional results and one death. The short term complications were post traumatic arthritis (n = 10) and osteonecrosis (n = 2). Conclusion: The THD occurrences are important in our emergency department. They are characterized by the place of motorcycle accidents and by the delayed reduction due to hospital’s locations and numbers and beliefs. A reduction before four hours, an earlier rehabilitation, a non-use of traction and a short hospitalization time below 14 days gave better results.

Total Hip Arthroplasty in Neglected Developmental Dysplasia Hip, a Case Report

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.

Unusual Posterior Traumatic Hip Dislocations at Yopougon/Abidjan Teaching Hospital

Traumatic dislocation of the hip is quite rare and accounts for 2% - 5% of all dislocations. We report on a case of a bilateral posterior hip dislocation associated with symmetric acetabular fracture and two cases of infracotyloid dislocation. The report included 2 men and one woman. The mean age of patients was 33 years. All dislocations followed a road traffic accident. Non-operative closed reduction was achieved within 19 hours of admission. The average follow-up time was 15 months. The hips were stable, mobile, and painless;and there was no radiographic sign of avascular necrosis of the femoral head.
