Retroversion of the acetabulum. A cause of hip pain.

Reynolds D, Lucas J, Klaue K.

Guy's Hospital, London, England.

We describe a little-known variety of hip dysplasia, termed 'acetabular
retroversion', in which the alignment of the mouth of the acetabulum does not
face the normal anterolateral direction, but inclines more posterolaterally. The
condition may be part of a complex dysplasia or a single entity. Other than its
retroversion, the acetabulum is sited normally on the side wall of the pelvis,
and its articular surface is of normal extent and configuration. The retroverted
orientation may give rise to problems of impingement between the femoral neck
and anterior acetabular edge. We define the clinical and radiological parameters
and discuss pathological changes which may occur in the untreated condition. A
technique of management is proposed.
