Abstract:
Objective:To explore the recent clinical curative effect of Tantalum rod in treating the early avascular necro-sis. Methods:From January 2008 to November 2008,the 25 patients (39 hips) with early avascular necrosis accepted tanta-lum rod placement and included 9 males (11 hips) and 16 females (28 hips) with an average age of 37 years old ranging from 18 to 74 years old. Four patients (6 hips) caused by Alcoholic,6 patients (8 hips) by hormone,2 cases (2 hips) by traumatic, 13 cases (23 hips) by idiopathic. Steinberg preoperative stage involved 7 hips in period I,24 hips in period II,8 hips in period III. Curative effect analysis included preoperative and postoperative Harris score ,radiographic changes and hip replacement for follow up to accept the end of the femoral head survival rate. Results:All patients were followed up for 6 to 47 months (aver-aged 37.4 months). All 12 hips imaging appeard progress,including tantalum rod exit in 1 hip,hip hemiarthroplasty collapse in 3 hips,the area increased to avascular necrosis in 8 hips. Six hips accepted total hip replacement ,including imaging progress in 5 hips (41.7%,5/12),no imaging progress in 1 hip (3.7%,1/27). All hips'Kaplan-Meier survival curves showed 6 month survival rate was(97.4±2.5)%after tantalum stick insertion,1 year survival rate was (94.7±3.6),and 2 year survival rate was (88.6±5.4)%,3 year survival rate was (72.5±11.2). Conclusion:It is effective for treatment of avascular necrosis of femoral head in Steinberg I and II by Tantalum rod ,and it can effectively relieve femoral head replacement time.
