Cemented allograft-prosthesis composite reconstruction for the proximal femur tumor.

Min L, Tang F, Duan H, Zhou Y, Zhang WL, Shi R, Tu CQ - Onco Targets Ther (2015)

Bottom Line: Nonunion of the greater trochanter was seen in six of the 12 patients (50.0%).Eight (32.0%) hips had resorption.There were no cases of recurrence, but metastasis was found in two hips.

ABSTRACT

Introduction: Cemented allograft-prosthesis composite (APC) reconstruction is one option following resection of the proximal femur tumor. However, rare studies have focused on the indications and complications. The goal of the present study was to (1) ascertain the indications for cemented APC arthroplasty in the proximal femur; (2) identify the detailed perioperative management; and (3) illustrate our experiences to avoid the complications of cemented APC.

Materials and methods: A total 28 patients who underwent cemented APC reconstruction of the proximal femur after tumor resection were retrospectively evaluated at a median follow-up of 56 months. Clinical records and radiographs were reviewed to evaluate patients' outcome.

Results: In our series, excluding three cases of death that had a short follow-up period, union occurred in 22 (88.0%) patients (range 9-18 months). Nonunion of the greater trochanter was seen in six of the 12 patients (50.0%). Eight (32.0%) hips had resorption. There were two (8.0%) hips that were observed to have asymptomatic wear of the acetabulum. The average Musculoskeletal Tumor Society (MSTS) score was 26.5 points. The average Harris Hip Score (HHS) score was 80.6 points. There were no cases of recurrence, but metastasis was found in two hips.

Conclusions: Mastering indications, perioperative management, and complication prevention are all very important in the APC reconstruction after resection of the proximal femur.

Mentions: Trochanteric union was defined as a lack of migration of the greater trochanter, with trabecular bridging; migration or a gap of more than 1 cm was regarded as nonunion.10 Nonunion of the greater trochanter was seen in six of the 12 patients (50.0%) in whom the host trochanter was preserved (Figure 3).
