Abstract:

BACKGROUND: Many treatment methods that keep their joints have been used to treat femoral head necrosis. Blood vessel free fibular grafting induces need long-term bed rest, larger damage, blood loss and complications during rehabilitation. Tantalum rod was difficult to artificial hip joint replacement in later.
OBJECTIVE: To evaluate the recent clinical effect and indications of allogeneic fibula implantation with core for the treatment of femoral head necrosis.
METHODS: A total of 103 patients (132 hips) with femoral head necrosis were involved, aged 43.2 (20-70) years. According to Steinberg stage, 13 hips at stageⅠ, 53 hips at stage Ⅲ, and 40 hips at stage Ⅲa, 26 hips at stage Ⅲb. The combination of core decompression and allogeneic fibular implantation with hole was used to treat the femoral head necrosis. Harris scores were used to evaluate hip function pre-operation and post-operation. The X-ray films were taken at 3, 6, 12 and 24 months after implantation to observe the repair progress of femoral head necrosis and to analyze the results.
RESULTS AND CONCLUSION: All patients were followed-up for 2.0-2.5 years (means 2.3 years). Preoperative Harris score was (64.7±7.8) points, 68.5 points on average, and postoperative score was (91.0±2.6) points, 91.4 points on average. There was significant difference between preoperative and postoperative Harris scores (P < 0.05). After 24 months, the X-ray film of all patients showed 106 hips improved, 7 hips unchanged, 10 hips deterioration and 9 hips failed, the total effective rate was 85.6%, and all the deterioration and failed patients were at stage IIIb. All patients had no any complications. The curative effect of core decompression and allogeneic fibula implantation with hole for the treatment of femoral head necrosis is confirmed, especially for Steinberg Ⅰ period, Ⅱ period and Ⅲ a period of young patients.
