Abstract

BACKGROUND:

The management of pelvic giant cell tumors (GCTs) involving the acetabulum remains a challenge for surgeons on how to balance the relative benefits of minimizing recurrence and maintaining postoperative hip function. The present study was to present and evaluate the clinical indications, operative technique, and outcomes of pelvic GCTs involving partial acetabulum treated with multiplanar osteotomy and reconstruction of autogenous femoral head bone grafts combined with cementless total hip arthroplasty (THA).

METHODS:

We retrospectively reviewed seven patients with pelvic GCTs involving partial acetabulum who underwent multiplanar osteotomy and reconstruction of autogenous femoral head bone grafts combined with cementless THA from January 2010 to October 2014. We assess the outcome including the bone graft healing, nonunion, hardware failure, infection, tumor recurrence, and metastasis. And the functional outcome was evaluated by the Musculoskeletal Tumor Society (MSTS)93 score.

RESULTS:

All patients were followed up for a mean of 38.1 months (range 26-61 months). All bone grafts are union. No failure of acetabular components, wound healing problem, or deep infection was suspected. No patient experienced metastasis. Recurrence was observed in one out of seven patients, treated by extended resection and implanting iodine ions in the surgical area. The mean MSTS93 score was 29.4 (range 28-30). All patients were disease-free and resumed activities of daily living at the most recent follow-up.

CONCLUSIONS:

As long as one of the two columns is retained and the resulting defect does not exceed the supra-acetabular line, multiplanar osteotomy and reconstruction of autogenous femoral head bone grafts combined with cementless THA is a viable strategy for the treatment of pelvic GCTs involving partial acetabulum. However, a large-scale prospective clinical study is still needed to verify these procedures.
