Metastatic bone disease resulting in acetabular destruction can provide the orthopaedic surgeon with the difficult challenge of achieving a stable reconstruction of the hip to provide pain relief and restoration of mobility.

We review of twenty patients with metastatic disease requiring major acetabular reconstruction presenting to our orthopaedic oncology unit over a five year period was undertaken. This yielded 15 female and 5 male patients with mean age 59 years. The primary lesion was breast (8 cases), renal (3) prostate (2), myeloma (2) and others (5) with a solitary acetabular metastasis in 75% of cases. Eight patients had received radiotherapy to the region pre-operatively.

In all cases, diseased bone was macroscopically cleared from the pelvis and reconstruction performed by means of a Harrington procedure with threaded pins passed antegrade from the iliac crest 915 cases) or mesh and screws (5 cases), all reinforced with cement around which a total hip arthroplasty was performed.

Mean follow-up was 16 months. Complications were broken pin (1 case), dislocation of femoral prosthesis (1) and deep venous thrombosis (1). Three patients died of their disease at a mean of 12 months from surgery. The remaining 17 patients continue to function at a satisfactory level with no patients having required revision surgery for loosening or deep infection.

We believe that surgical reconstruction of the acetabulum is worthwhile and can provide these deserving patients with improvement in quality of life.
