    Abstract:
    The pericapsular osteotomy proposed by Pemberton enables to obtain a real application of the socket around the Y-shaped cartilage. Thereby, it has a very particular role among pelvic osteotomies, to which it cannot be compared. As a matter of fact, its indications are different. The study of a series of 32 Pemberton's osteotomies enables to appreciate the remodeling obtained at the level of the hip. The analysis of the results we got after a post-operative period of 1 to 8 years enables to determine the indications of that intervention better. Pemberton's osteotomy reduces the radius of curvature of the socket. Thus, it is particularly adapted to the cure of dysplasia with a too broad socket, the center of which does not correspond with the center of the femoral head. Under these conditions, Pemberton's osteotomy enables a recentering of the joint and provides a satisfactory superior and anterior covering of the femoral head (21 cases). On the contrary, when the head and the socket have a common center, that intervention, in reducing the capacity of the acetabulum, induces an articular incogruity (5 cases). A secondary remodelong occurs assuredly, but there is still an insufficient covering. Before carrying out a Pemberton's osteotomy, we advise to study its effects on a tracing of the radiography of the pelvis. Thus, some unsatisfactory results, which are generally bad indications, could be reduced.
