NONOPERATIVE AND JOINT PRESERVING SURGICAL TREATMENTS

The Use of Trabecular Metal in Osteonecrosis of Femoral Head

Introduction: It is desirable to delay or avoid total joint replacement in young patients who have osteonecrosis of femoral head. There are some head preserving surgical procedures, which are including osteotomy, core decompression and bone graft. The vascularized fibular graft has been reported as reliable procedure but unfortunately it has donor site morbidity and is considered as technically demanding procedure. Therefore, materials have been developed to substitute for structural fibular graft. New trabecular metal has been developed to be used for osteonecrosis of femoral head.

Purpose of this study was to review clinical outcomes of trabecular metal for intervening in osteonecrosis of femoral head.

Materials and Methods: 7 patients (8 hips) exhibiting osteonecrosis of femoral head received core decompression and trabecular metal implant from March 2003. Stage of osteonecrosis was I or II according to Ficat and Arlet except one case (III). Procedure consists of core dompression and trabecular metal (poros tantalum, Zimmer inc./ Implex Corp) rod insertion. Clinical outcome measures include HHS scored pre-op, at 3, 6month and radiographic data is collected at the same times.

Results: All 7 patients are doing well. Radiographic review shows no evidence of further collapse.

Conclusion: Even though short term F/U, we think that the use of trabecular metal in osteonecrosis patients is simple, safe, effective for salvage of hip.
