Abstract

Background: After internal hemipelvectomy, successful pelvic reconstruction can provide a durable and pain-free reconstruction for the young, active patient. Such reconstruction is extremely challenging, and often patients have less than optimal ambulation with a limp, leg length discrepancy, or leg instability. The authors present an innovative method for pelvic ring reconstruction using a vascularized double-strut fibular bone flap that provides a stable pelvis and recovery of normal or near-normal gait.

Methods: From December of 2003 to November of 2005, six sarcoma patients underwent internal hemipelvectomy and pelvic ring reconstruction with a vascularized double-strut fibular bone flap. The length of each strut was 7 to 12 cm.

Results: All bone flaps survived. The mean follow-up was 18 months (range, 8 to 32 months). Radiographic evidence of bone bridging was seen at a mean of 2.5 months (range, 2 to 4 months). The mean time to ambulation without assistance was 8 months (range, 5 to 18 months). One patient died as a result of metastatic disease. The remaining five patients are ambulatory with a mild limp or no limp.

Conclusion: Use of a vascularized double-strut fibular bone flap for pelvic ring reconstruction is effective in facilitating early ambulation and restoring normal to near-normal gait in patients undergoing internal hemipelvectomy.
