Femoral head bone viability after free vascularized fibular grafting for XXXX : SPECT/CT study.

@entity1 @entity85 @entity2530
PURPOSE: To evaluate femoral head bone viability following free vascularized fibular grafting (FVFG) for @entity2530 using SPECT/CT imaging. METHODS: Ten hips (9 @entity1 ) with @entity2530 of the femoral head (ONFH) undergoing FVFG were prospectively enrolled. Four cases showed ARCO stage II, while six showed ARCO stage III. The mean age at surgery was 15.7 years (range, 13-22 years). Hip Harris Score (HHS) was measured pre- and post-operative. Bone scintigraphy with SPECT/CT was performed at 2 weeks and 6 months following surgery. RESULTS: Mean follow-up was 4.0 years (range, 2-5.9 years). Mean HHS increased from 37.2 to 92.3. SPECT/CT findings revealed a progressive increase of femoral head uptake in all cases, suggesting subchondral graft bone viability. No progressive @entity85 was evidenced in radiographic evaluation at final follow-up. CONCLUSIONS: This study demonstrates FVFG's capacity for revitalizing femoral head subchondral bone grafting in @entity1 with ONFH, surgically treated following Urbaniak's technique.    2015 Wiley Periodicals, Inc.
