Periacetabular resections for primary malignancies and metastatic disease require reconstruction to restore weightbearing along anatomic axes. Without reconstruction, patients are unable to ambulate independently, and are left with a disfigured pelvis and shortened limb. The current authors describe a reconstruction technique using Steinmann pins augmented with methylmethacrylate reconstruction, and autoclaved autografting, in combination with total hip arthroplasty, after resection of primary sarcomas of the pelvis. For this study, the results of 15 patients at two institutions who had surgery by the same surgeons were retrospectively reviewed. The patients had primary malignant tumors of the pelvis, and had limb-sparing resections between 1985 and 2000. Three measures of outcome were evaluated: survival, function, and pain. The surgical method uses Steinmann pins with bone cement to fill in areas of bone loss that cannot be reconstructed with autoclaved autograft. A constrained polyethylene acetabular component is cemented into this bed. Twelve patients had chondrosarcoma and one patient had osteosarcoma. The remaining two patients had alveolar sarcoma of soft parts. Six patients died of disease. Seven patients were alive with no evidence of disease, and two were alive with disease at the most recent followup. Early return to ambulation without assistive devices occurred in nine of 15 patients. The functional outcome of this technique compares favorably with others reported. Sixty percent of patients ambulated independently without assistive devices, compared with 0% to 10% in other studies reviewed. The time required for independent gait is similar to recovery from a total hip arthroplasty. Moreover, this method minimized leg length discrepancy, while also producing a favorable cosmetic result. |
