Hip dislocation associated with Down syndrome is relatively rare. Hip dislocation can progress to severe subluxation or habitual dislocation if the initial therapy is improperly performed. However, definitive treatment guidelines for conservative and surgical therapy for hip dislocation in patients with Down syndrome have not been established. This article describes a case of a 12-year-old girl...

The Norwegian Arthroplasty Register has shown that several designs of uncemented femoral stems give good or excellent survivorship. The overall findings for uncemented total hip replacement however, have been disappointing because of poor results with the use of metal-backed acetabular components. In this study, we exclusively investigated the medium-to long-term performance of primary uncement...

Although surgical techniques for treating acetabular fracture are evolving, the use of periacetabular screws is common, and their placement in acetabular surgery is still technically demanding. For instance, intraarticular screw perforation is a serious complication that may occur during surgical treatment of an acetabular fracture. Here, we describe the case of a 50-year-old female who experie...

BACKGROUND Massive bone defects of the acetabulum with pelvic discontinuity are one of the major problems in revision total hip arthroplasty. Several techniques have been described for repair of acetabular defect; however, reconstruction of acetabulum with massive bone defect is still a major problem. We describe a patient who required four revision total hip arthroplasty during a 24-year perio...

Finite element analysis was used to examine the initial stability after hip resurfacing and the effect of the procedure on the contact mechanics at the articulating surfaces. Models were created with the components positioned anatomically and loaded physiologically through major muscle forces. Total micromovement of less than 10 mum was predicted for the press-fit acetabular components models, ...

e Bernese rotational acetabular osteotomy (RAO) was developed in 1983 (1) in order to prevent the development of arthrosis in young patients with hip dysplasia, and several reports on satisfactory results have subsequently been published (2–9). e RAO performed through the two most frequently used approaches, the ilioinguinal and Smith-Petersen, requires a broad dissection of the pelvic bones an...

Combined pelvic ring and acetabular injuries present a management challenge. The literature on this topic is scarce, with few outcomes studies available. This retrospective study assessed whether the incidence of postoperative displacement and loss of reduction is higher with combined injuries compared with isolated pelvic ring injuries and isolated acetabular fractures. The charts and radiogra...

This study was conducted to identify the factors influencing mechanical failure of cementless acetabular reconstruction for arthropathy after operative treatment of acetabular fractures. Fifty-six patients (56 hips) undergoing cementless total hip arthroplasty were enrolled and followed for a mean of 120 months (range, 60-180 months). The 10-year survival rate, with mechanical failure (radiogra...

Acetabular fractures can be treated with variable method. In this study, acetabular posterior wall fracture was treated with arthroscopic reduction and fixation using cannulated screw. The patient recovered immediately and had a satisfactory outcome. In some case of acetabular fracture could be good indication with additional advantages of joint debridement and loose body removal. So, we report...

Anatomic data regarding femoral version, neck-shaft angle, and acetabular anteversion are still limited in Chinese Han adult population. The aim of this study was to investigate the effects of age, sex, and body laterality on the 3 important anatomic indicators in Chinese Han healthy adults. Measurements were performed independently by 3 experienced observers using the picture archiving and com...
