OBJECTIVE
this study aimed to evaluate the fixation of the trabecular metal wedge in patients undergoing revision of total hip arthroplasty.
METHODS
twenty-three cases with minimum grading of Paprosky II-B that were operated between July 2008 and February 2013 were evaluated. These cases were evaluated based on radiographs before the operation, immediately after the operation and later on after the operation. Loss of fixation was defined as a change in the abduction angle of the component greater than 10° or any mobilization greater than 6 mm.
RESULTS
it was found that there was 100% fixation of the acetabula after a mean of 29.5 months. One case underwent removal of the implanted components due to infection.
CONCLUSIONS
there is still no consensus regarding the best option for reconstructing hips with bone loss. However, revision using a trabecular metal wedge has presented excellent short- and medium-term results. This qualifies it as an important tool for achieving a fixed and stable acetabular component.
目的
本研究旨在评估在全髋关节置换翻修手术患者中使用小梁金属楔形块的固定情况。
方法
对2008年7月至2013年2月间手术的23例最低Paprosky II - B级病例进行评估。这些病例根据术前、术后即刻及术后随访的X线片进行评估。固定失败定义为假体外展角度变化大于10°或任何移动大于6毫米。
结果
平均29.5个月后发现髋臼固定率为100%。1例因感染取出植入部件。
结论
对于骨缺损髋关节重建的最佳选择尚无共识。然而，使用小梁金属楔形块进行翻修已呈现出优异的短期和中期效果。这使其成为实现髋臼假体固定和稳定的重要工具。
