The acetabular rim syndrome. A clinical presentation of dysplasia of the 
hip.Klaue K, Durnin CW, Ganz R.

The acetabular rim syndrome is a pathological entity which we illustrate 
by reference to 29 cases. The syndrome is a precursor of osteoarthritis 
of the hip secondary to acetabular dysplasia. The symptoms are pain and 
impaired function. All our cases were treated by operation which 
consisted in most instances of re-orientation of the acetabulum by 
peri-acetabular osteotomy and arthrotomy of the hip. In all cases, the 
limbus was found to be detached from the bony rim of the acetabulum. In 
several instances there was a separated bone fragment, or 'os acetabuli' 
as well. In acetabular dysplasia, the acetabular rim is subject to 
abnormal stress which may cause the limbus to rupture, and a fragment of 
bone to separate from the adjacent bone margin. Dysplastic acetabuli may 
be classified into two radiological types. In type I there is an 
incongruent shallow acetabulum. In type II the acetabulum is congruent 
but the coverage of the femoral head is deficient.
