We present a prospective study of impaction grafting using collared textured stems in femurs with massive defects (defined as requiring >150 cm(3) of cancellous allograft). Eighteen hips were followed for a minimum of 2 years. Average Harris hip scores increased from 50 preoperatively to 83 at most recent follow-up. Seventeen hips were functioning well at the time of most recent follow-up and exhibited no stem subsidence or aseptic loosening. One hip was associated with visible subsidence and required further revision. Single-photon emission computed tomography analyses performed at an average of 37 months indicated active graft reorganization in all cases studied. Impaction allografting with collared textured stems for massive defects demonstrates good intermediate-term clinical results and may be a useful alternative to allograft stem composites and megaprostheses.
我们开展了一项前瞻性研究，在存在大块骨缺损（定义为需要超过150立方厘米的松质骨同种异体骨）的股骨中使用带颈纹理柄进行打压植骨。对18例髋关节进行了至少2年的随访。平均Harris髋关节评分从术前的50分提高到最近一次随访时的83分。在最近一次随访时，17例髋关节功能良好，未出现柄下沉或无菌性松动。1例髋关节出现明显下沉，需要进一步翻修。平均在37个月时进行的单光子发射计算机断层扫描分析表明，在所有研究病例中均有活跃的植骨重组。使用带颈纹理柄进行大块骨缺损的打压同种异体骨移植显示出良好的中期临床结果，可能是同种异体骨柄复合物和大型假体的一种有用替代方法。
