    Abstract:
    OBJECTIVE: To investigate the clinical efficacy of the pith decompression of the femoral head and fibular allograft transplantation in the treatment of early stage avascular necrosis. METHODS: From January 2004 to November 2008, 32 hips of 25 patients with avascular necrosis of femoral head of Ia-IIIb period were treated by the pith decompression of the femoral head and fibular allograft transplantation, hollow lag screw fixation, included 17 males and 8 females, aged from 20 to 55 years old (39.1 years on average). Preoperative pain was from 2 to 14 months (means 5.5 months). All patients were applied on conventional X-ray films, MRI examination, Harris score. RESULTS: The patients were followed up for 12 to 48 months (means 36.4 months). X-ray film showed 21 hips of 18 cases improved,6 hips of 4 cases unchanged, no collapse of articular surface, 3 hips of 2 cases deterioration, 2 hips of 1 case failed. Preoperative Harris score was (77.0 +/- 8.0) and postoperative (90.6 +/- 2.5), there was a significant difference (t = 1.67, P < 0.05). CONCLUSION: Pith decompression of the femoral head and fibular allograft transplantation in the treatment of early stage avascular necrosis of femoral head has advantage of joint function in bed-ridden after a short time, quick recovery,clinical symptoms improved. Its short-term efficacy is certain but long-term efficacy is still need further observation.
