Total Hip Reconstruction In Acetabular Dysplasia
Housam El-Din Farouk Aly Raslan;
Abstract
Treatment of congenital dislocation of the hip with total hip arthroplasty in adults is a challenging surgical procedure. (Keerati etal,
1999).
Early in the development of total hip arthroplasty, attempts to reconstruct the hips of adults who had congenital dislocation proved to be unsuccessful and the initial impression was that such hips should not be operated on. (Hartofilakidis etal, 1998).
The treatment of the dysplastic hip depends on the severity of the disease, the extent of secondasy oseoarthritis, the age and the functional goals of the patient, also on the availability of bone stock. (Haddad etal, 2000).
The reconstruction of the acetabulum is the most important part of the whole procedure. It determines The approach that is used, the type of bone graft (if any) that is needed, and in many cases, the type of
femoral reconstruction that should be performed. The best bone stock available for reconstruction is usually at the true acetabulum, but this may not be the case if there has been a previous acetabular osteotomy or shelf procedure. The acetabular component is optimally placed at the
site of true acetabulum, although a high, but not lateral, P.OSition can be
'•
accepted. Obtaining satisfactory acetabular coverage is the key step. for
most patients this requires only deeper reaming and use of a small
•• diameter acetabular component that is porous-coated or inserted with cement. Alternatives include controlled acetabular medialization, the use
of cement or bone graft to augment the acetaulum, and the use of reinforcement ring.
