This paper introduced a method of modifiedWagner’s procedure, called acetabular rotation osteotomy for the treatment of severeacetabular dysplasia in ten adults patients. These were followed up for 1-4 years. Fivecriteria including pain, gait, range of motion, measurement of roentgenographic changees,and CT scan were evaluated. From the limited information of this paper, it showed thatin all cases pain improved and range of motion did not reduced significantly. Comparingthe pre- and post-operative x-ray films, CE angle increased and exceeded the normal val-ue. Tonnis hip value decreased and approached the normal value, anteversion of theacetabulum improved, and the percentage of acetabular coverage increased as well.展开更多

Twenty-four hips with hip dyaplasia who underwent CPO or RAO were included in this study. Six hips had grade 0 and eighteen hips had grade 1 OA according to the Tönnis classification. We excluded patients with moderate and severe hip osteoarthritis and major femoral head deformities. Preoperative radiograph was evaluated on sharp angle, center-edge angle, alpha angle, crossover sign and posterior wall sign. Crossover signs were revealed in 7 hips (29.2%);posterior wall signs were revealed in 16 hips (66.7%);and cam-type deformities with an alpha angle of ≥50.5°were observed in 19 hips (79.2%) in preoperative evaluation. As determined using the Tönnis scale, no progression of osteoarthritis was found in 16 of the 24 hips;there was a one-grade progression in 8 hips. Among the 8 hips, either positive cross-over sign or posterior sign in acetabulum, and an alpha angle of ≥50.5°in femur were observed in six hips with progression of osteoarthritis. The presence of cam-type deformity and acetabular retroversion in patients who underwent RAO or CPO was relatively high in preoperative radiographs, and caution should be employed during surgery in patients with DDH. There is a possibility of secondary FAI due to excessive forward coverage of the bone fragments after RAO and CPO.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
