Background. Periacetabular resections with reconstruction has high rates of complications due to the complexity of the reconstruction. We have improvised a novel technique of reconstruction for type II and type II + III pelvic resections with the use of a commercially available acetabulum reconstruction cage (gap II, Stryker) and threaded rods. Objectives. The aim of our study is to determine t...

BACKGROUND Dislocation may complicate revision total hip arthroplasty (THA). We examined the correlation between the components revised during hip arthroplasty (femur only, acetabulum only and both components) to the rates of dislocation in the first and multiple revision THA. METHODS We obtained data from consecutive revision THAs performed between January 1982 and December 2005. Patients we...

We have reviewed 65 bipolar arthroplasties of the hip in 55 patients with osteoarthritis secondary to dysplasia. The mean age at operation was 56 years (42 to 79) and the mean period of follow-up was 7.2 years (5.0 to 13.0). The average Merle d'Aubigné and Postel score before operation was 10.3 and at final follow-up 15.0. There were excellent or good results in 42 hips (65%). Migration of the ...

The acetabular cartilage complex is interposed between Figure 1: Hip Growth the ilium, ischium, and the pubis. This complex is composed of epiphyseal growth-plate cartilage adjacent to these bones and articular cartilage around the acetabular cavity. Interstitial growth of the triradiate cartilage leads to expansion and enlargement of the acetabulum (25). Development of the acetabulum and femor...
