background:management of acetabular fractures in the senior population can be one of the most challenging injuries tomanage. furthermore, treating surgeons have a paucity of information to guide the treatment in this patient population.the purpose of this study was to determine: (1) demographic and epidemiologic data, (2) mortality rates for nonoperativecompared to operative management at diffe...
BACKGROUND Residual acetabular dysplasia is one of the most common complications after treatment for developmental dysplasia of the hip. The acetabular growth response after reduction of a dislocated hip varies. The options are to wait and add a redirectional osteotomy as a secondary procedure at an older age, or to perform a primary acetabuloplasty at the time of the open reduction to stimulat...
PURPOSE OF THE STUDY To present the results of primary total hip arthroplasty (THA) with use of the hemispheric threaded Ultima cup at 8.5-year follow-up. MATERIAL Between 1996 and 1999, a total of 40 Ultima acetabular components were used in 33 patients (15 men and 18 women). The average age at the time of surgery was 61.2 years (range, 45 to 71). By the end of 2006, 36 cups were assessed. I...
Fifty-seven cemented total hip arthroplasties (THAs) were reviewed in cases of osteoarthrosis secondary to congenital dysplasia or dislocation. The bearing surface of the prosthesis used in this series consists of a polyethylene acetabular component on an alumina ceramic head. All acetabular components were positioned at the same level as the original acetabulum, and an autologous femoral head ...
BACKGROUND In patients with femoroacetabular impingement (FAI), acetabular rim trimming removes the offending area of the acetabular deformity in patients with pincer-type and mixed-type FAI to improve hip joint kinematics. Although the rationale for arthroscopic acetabular rim trimming in patients with FAI is well established, the amount of rim resection has not been quantified, and the thresh...
The purpose of this multi-surgeon study was to assess and compare the accuracy of acetabular component placement, leg length discrepancy (LLD), and global offset difference (GOD) between six different surgical techniques and modes of guidance in total hip arthroplasty (THA). A total of 1980 THAs met inclusion criteria. Robotic- and navigation-guided techniques were more consistent than other te...
We treated eight dysplastic acetabula in six skeletally mature patients with Down's syndrome by a modified Bernese periacetabular osteotomy. The mean age at the time of surgery was 16.5 years (12.8 to 28.5). Mean length of follow-up was five years (2 to 10.4).Pre-operatively the mean (Tonnis) acetabular angle was 28 degrees, the centre-edge angle was -9 degrees, and the extrusion index was 60%;...
