摘要:

背景:传统全髋关节置换在年轻、活动量高的患者中有较高的早期失败率。大直径金属对金属全髋关节置换具有杰出的稳定性、低磨损性,成为解决上述问题的一个重要选择。
目的:评价大直径金属对金属全髋关节置换术的临床效果。
方法:2007-04/2009-10常州市中医医院骨科对48例49髋股骨头缺血性坏死、骨关节炎、强直性脊柱炎、髋关节发育不良、股骨颈骨折及其并发症患者进行了大直径金属对金属全髋关节置换。置换后的髋关节功能采用Harris标准评定,每一例患者摄标准的骨盆平片,观察假体位置,比较置换后随访X射线平片的变化。
结果与结论:全部患者均获得随访,时间3~34个月,平均20.2个月。患者置换后无脱位,无感染,无髋臼及股骨骨折。2例髋臼假体周围发现透亮带。1例出现腹股沟区疼痛。2例出现关节周围响声。最近一次随访Harris平均评分96分,优良率100%。提示大直径金属对金属全髋关节置换可有效的治疗股骨头缺血性坏死、骨关节炎、强直性脊柱炎、髋关节发育不良、股骨颈骨折及其并发症,近期随访结果满意。

Abstract:

BACKGROUND: Traditional total hip arthroplasty (THA) has high early failure rate in the treatment of young patients with frequent activity. Large diameter metal-on-metal THA exhibits stability, low wearing and could become an alterative.
OBJECTIVE: To evaluate the clinical efficacy of large diameter metal-on-metal THA.
METHODS: From April 2007 to October 2009, 49 hips in 48 cases with osteonecrosis, osteoarthritis, ankylosing spondylitis, hip dysplasia, fracture of femoral neck and its complications were treated with the large diameter metal-on-metal THA in Department of Orthopaedics, Changzhou Traditional Chinese Medical Hospital. The hip function was evaluated by Harris scores. Pelvis was photographed to observe prosthesis location. All the patients were followed up after operation, and X-ray changes were compared.
RESULTS AND CONCLUSION: Patients were followed up for an average period of 20.2 months (3-34 months). There was no dislocation, infection, acetabular or femoral fracture in all patients. No radiolucent line was observed. Radiolucent line existed around acetabular prosthesis in two hips. One patient developed groin pain after the operation and sound around the joint appeared in two patients. The average Harris score was 96 in the latest follow-up with an excellent and good rate of 100%. Results showed that the large diameter metal-on-metal THA is effective for the patients with osteonecrosis, osteoarthritis, ankylosing spondylitis, hip dysplasia, fracture of femoral neck and its complications. The short-term results are satisfied.
