Abstract

PURPOSE

To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA).

METHODS

62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent uncemented THA using the trident acetabular cup. Obese elderly women at risk of femoral neck fracture and patients with large subchondral pseudocysts or a history of avascular necrosis of the femoral head were assigned to uncemented THA. Acetabular reamings were collected; marginal osteophytes were not included. The reamings were dehydrated, defatted, and weighed.

RESULTS

The mean weight of acetabular reamings was not significantly different between patients undergoing hip resurfacing and uncemented THA (p=0.57).

CONCLUSION

In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and removal of excessive bone stock.

摘要

目的

比较髋关节表面置换术与非骨水泥型全髋关节置换术（THA）中髋臼去除骨量的情况。

方法

对62例连续的髋关节骨关节炎患者进行前瞻性研究。24例男性和7例女性，年龄40至86岁（平均59岁），接受了伯明翰髋关节表面置换术。13例男性和18例女性，年龄34至88岁（平均61岁），使用三叉戟髋臼杯进行了非骨水泥型THA。有股骨颈骨折风险的肥胖老年女性以及有大的软骨下假囊肿或股骨头缺血性坏死病史的患者被分配接受非骨水泥型THA。收集髋臼磨屑；不包括边缘骨赘。将磨屑脱水、脱脂并称重。
