我们分析了连续206例使用大直径陶瓷对陶瓷轴承进行全髋关节置换术的结果。平均随访28个月，平均Harris髋关节评分从54分提高到92分。有15个髋关节(7.3%)有吱吱声。在年龄、体重、身高、BMI、活动范围、股骨头直径、腿长和偏移量或旋转中心方面，安静和吱吱作响的髋关节之间没有显著差异。尖叫声的发生率与杯体倾斜度和前倾角的增加之间没有相关性。在莱温内克安全区内的杯子中，有5.2%的杯子发出吱吱声。没有髋关节需要修改才能发出吱吱声。虽然大直径陶瓷轴承可能会发出吱吱声，但我们使用大头陶瓷轴承进行手术的早期结果令人鼓舞。然而，需要长期的随访。(C)2014 Elsevier Inc.保留所有权利。
We analyzed the results of 206 consecutive total hip arthroplasties performed using large diameter ceramic-on-ceramic bearings. At an average follow-up of 28 months, the mean Harris Hip Score improved from 54 to 92. Fifteen (7.3%) hips were noted to squeak. There was no significant difference between silent and squeaking hips with regards to age, weight, height, BMI, range of movement, femoral head diameter, leg length, and offset or center of rotation. No correlation was present between incidence of squeaking and increasing cup inclination and anteversion. 5.2% of cups orientated within Lewinnek's safe zone squeaked. No hips required revision for squeaking. While large diameter ceramic bearings may produce squeaking, our early results of surgery using large head ceramic bearings are encouraging. However, long-term follow-up is required. (C) 2014 Elsevier Inc. All rights reserved.
