双极长柄人工股骨头置换治疗高龄粉碎性股骨转子间骨折的临床应用

目的探讨双极长柄人工股骨头置换治疗高龄股骨转子间粉碎性骨折的临床应用。方法2000年3月～2003年8月选用双极长柄人工股骨头置换治疗72岁以上股骨转子间粉碎性骨折18例，男8例，女10例。年龄72～91岁。取后外侧切口，术中注意保留大小粗隆部位的骨折块，争取将其重新复位，用钢丝固定，安放人工股骨头。对住院时间、术后负重、行走时间、并发症及术后病死率进行随访观察。结果18例术后均获6～28个月随访，平均16．2个月。住院时间平均16d，术后17例32d完全负重行走，1例因其他内科疾患扶拐行走；术后并发髋关节疼痛1例，术后1年死亡1例，余17例健在。结论双极长柄人工股骨头置换治疗高龄粉碎性股骨转子间骨折，术后恢复好，能早期负重下地，并发症少。

THE CLINICAL EFFECT OF BIPOLAR LONG-STEM PROSTHETIC REPLACEMENT ON THE TREATMENT OF COMMINUTED INTERTROCHANTERIC FRACTURE OF HIP IN THE ELDERLY OSTEOPOROTIC PATIENTS

Objective To evaluate the clinical effect of bipolar long stem prosthetic replacement on the treatment of comminuted intertrochanteric fracture of hip in the elderly osteoporotic patients. Methods From March 2000 to August 2003, 18 patients who were more than 72 years old with comminuted intertrochanteric fracture were treated with bipolar long stem prosthetic replacement. There were 8 males and 10 females (aged from 72 to 91). Fractured fragments of large trochanter and minor trochanter should be preserved during the operation so that the fragments can be fixed with steel wires and insertion of artificial femoral head.The surgical approach and operative technique, the average course of treatment in hospital, the average time to ambulate with full weight bearing on the operated limb after the operation, complication, and mortality were observed. Results All patients were followed up 6 to 28 months(16.2 months on average). The average course of stay at hospital was 16 days. The average time to ambulate was 32 days. The incidence of the pain of the hip joint was one eighteenth, and one patient due to another disease was unable to walk without using two crutches one month after the surgery. The mortality of the patients was one eighteenth one year after the surgery. Conclusion Bipolar long stem prosthetic replacement for the treament of comminuted intertrochanteric fractures in the elderly osteoporotic patients proves to be a suitable alternative. Patients have better prognosis, early full weight bearing, rapid rehabilitation, and fewer complications.
