Abstract:

Objective   To compare the clinical effect between Porous tantalum screw and quadratus femoris muscle-pedicle bone graft in treating Ficat stage II necrosis of the femoral head. Methods    36 cases (46 hips) of Ficat stage II necrosis of the femoral head, dated from July 2006 to April 2009, were studied, including 29 males and 7 females. aged. The average age was 39.2 (26-59) years. 12 cases (16 hips) undergone porous tantalum screw insertion while 24 cases (30 hips) received quadratus femoris musclepedicle bone graft transplantation. The X-ray results and Harris score after the operations were evaluated.  Results     The duration of follow-up was 8-32 months. There was one collapse of the femoral head in the screw group and eleven collapses in the graft group. The post-operation Harris score was 91.4 and 80.7, respectively. Conclusion  Comparing with the quadratus femoris muscle-pedicle bone graft, porous tantalum screw shows more satisfactory results in treating Ficat stage II necrosis of the femoral head.
