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

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

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.

文摘全身麻醉下闭合复位加髋人位石膏固定是治疗24月龄以下发育性髋关节脱位(developmental dislocation of the hip,DDH)的通用方法,但闭合复位后仍有约1/3的患儿存在残余髋臼发育不良。尽管骨盆截骨术正越来越多地应用于残余髋臼发育不良的治疗,但其手术时机和手术指征仍不明晰。本研究拟通过一项多中心前瞻性非随机对照试验探讨DDH闭合复位后残余髋臼发育不良的手术干预时机和指征。研究设计拟纳入283例DDH闭合复位后残余髋臼发育不良患儿,包括观察组183例,手术组(采用骨盆截骨术)100例。手术组根据患儿年龄采用Salter、Pemberton、骨盆三联或髋臼周围截骨术。所有患儿随访10年,拟在DDH闭合复位后8个时间点(闭合复位术后1、2、3、4、5~6、7~8、9~10年以及10年以上)拍摄髋关节正位X线片,测量髋臼指数(acetabular index,AI)、中心边缘角(center-edge angle of wiberg,CEA)和Reimer指数(Reimer's index,RI),根据末次随访时正位X线片上髋关节Severin分级分为满意组(Severin分级为Ⅰ、Ⅱ级)和不满意组(Severin分级为Ⅲ、Ⅳ级),利用Logistic回归和Cox回归分析残余髋臼发育不良的风险因素,比较两组患儿AI、CEA、RI及Severin分级情况。这一多中心前瞻性研究可以为DDH闭合复位后残余髋臼发育不良的手术干预时机和指征提供循证医学证据。
文摘发育性髋关节脱位(developmental dysplasia of the hip,DDH)是指髋关节结构及功能上的异常,其治疗目的在于恢复髋臼和股骨头的同心圆复位,保证其正常的生长发育。国内外对不同年龄段DDH患儿的治疗方式比较成熟,但对于18~24月龄DDH患儿的治疗方式选择存在较大争议,由于疾病预后以及手术创伤、费用、时长等因素影响着治疗方式的选择,因此至今尚没有明确的治疗方案。目前采用的手术方法主要包括闭合复位、单纯切开复位及骨盆截骨术,然而每种治疗方式下都有部分患儿存在严重并发症,如残余发育不良(residualacetabular dysplasia,RAD)和股骨头缺血性坏死(avascular necrosis,AVN)。由于DDH患儿术后并发症的影响因素复杂,且18~24月龄这一年龄段髋臼发育的特殊性,如何选择适合不同患儿的手术方法已成为当前临床治疗的难点。本文就18~24月龄DDH患儿的手术治疗研究进展进行综述,旨在为该年龄段患儿选择合适的手术方案提供参考依据。
文摘背景:发育性髋关节发育不良常易导致患儿肢体畸形,其诊疗的相关研究已逐渐明确;近来有限元法因其优势在发育性髋关节发育不良的相关研究中受到学者重视。目的:通过文献检索综述有限元法在儿童发育性髋关节发育不良及治疗中的研究进展,分析总结其优势与不足,并探讨未来进一步研究的方向及应用前景。方法:应用计算机在Pub Med、SCI、CBM和中国知网数据库中检索2014年1月至2023年11月发表的相关文献,以“developmental dysplasia(dislocation) of the hip,dysplasia of the hip,finite element analysis(method),pavlik harness,fixation in herringbone position,biomechanics,pelvic osteotomies,pemberton,salter,dega,periacetabular osteotomy,children”为英文检索词,以“发育性髋关节发育不良,发育性髋关节脱位,髋关节发育不良,儿童,有限元,Pavlik吊带,人字型固定,生物力学,骨盆截骨术,髋臼周围截骨术”为中文检索词,同时纳入少量远期文献,通过筛选最终纳入62篇文献进行分析。结果与结论:(1)儿童发育性髋关节发育不良髋关节力学环境异常,髋臼内部压力不均匀、应力增大并集中,关节接触面积减小,股骨颈局部应力集中;(2)在Pavlik吊带及人字型固定位患髋力学环境改善,集中的高应力区域消失,关节接触面积增加,但外展角度过大会导致髋臼及股骨头外侧应力增加;(3)骨盆截骨术治疗后髋关节及骶髂关节应力环境得到改善,3种截骨术没有单一的铰链,其应力负载部位因患儿年龄而存在差异;(4)髋臼周围截骨术治疗后关节接触压力接近正常,而非球形股骨头者恢复困难;(5)术后X射线片表现不能说明关节接触力学达到最佳;(6)提示利用有限元法可以获得体内无法测量的信息,其在虚拟环境中操作不受时间和伦理的限制;能直观地看到正常与发育性髋关节发育不良患者髋关节应力变化的区域,从力学角度说明治疗的有效性,为需要截骨手术治疗的患者建立特定的有限元模型、量身定做手术计划;发育性髋关节发育不良的有限元建模及儿童髋关节材料特性参数尚无规范、统一的标准,由于有限元固有的局限性,目前还不能分析同时包含骨骼、软骨、韧带、肌肉等元素的模型;有限元分析操作难度较大,虽有优势但不具普适性,且目前的研究样本量较少,还需进一步扩大及验证。
