Trapeziometacarpal instability with trapezial dysplasia is a disabling condition long before the radiological changes of osteoarthritis appear. In dysplastic joints surgical soft tissue correction fails to prevent the instability, requiring a correction of the bony anatomy. We combined two techniques described in the past, an abduction osteotomy of the first metacarpal and an opening wedge oste...

In order to evaluate the relationship between acetabular and proximal femoral alignment in the initiation and evolution of osteoarthritis of the dysplastic hip, the acetabular and femoral angles were calculated geometrically from radiographs of 62 patients with pre-arthrosis and early osteoarthritis. The sum of the lateral opening angle of the acetabulum and the neck-shaft angle was defined as ...
