The purpose of this study was to assess the outcomes of distal tibial structural allograft to obtain a stable TTC fusion.
Retrospectively, ten patients were carried out with a minimum one year follow-up. The median age was 72 (33-81). The median BMI was 28 (24-33). Indications for TTC arthrodesis included failed total ankle arthroplasty (n=7 patients), prior nonunion (n=2 patients), and a trauma injury.
Union rate was 80%. The median initial height of the distal tibial allograft was 19mm (14-24mm). In seven cases the allograft did not lose height. The AOFAS score median was 69 (31-84). SF-12 median physical component was 39 (30-53), and 59 (23-62) for mental component. The VAS median was 2 (0-8).
TTC using distal tibial allograft shows a lower rate of collapse than other structural grafts and provides a fusion rate higher or in accordance with the literature.
Level IV, retrospective case series.
本研究的目的是评估胫骨远端结构性同种异体骨移植以实现稳定的胫距跟（TTC）融合的效果。
回顾性研究了10例患者，进行了至少一年的随访。中位年龄为72岁（33 - 81岁）。中位体重指数（BMI）为28（24 - 33）。TTC关节融合术的适应症包括全踝关节置换失败（7例患者）、既往骨不连（2例患者）和创伤性损伤。
融合率为80%。胫骨远端同种异体骨的初始中位高度为19mm（14 - 24mm）。7例中同种异体骨未出现高度丢失。美国足踝外科协会（AOFAS）评分中位数为69（31 - 84）。简明健康调查量表（SF - 12）身体维度中位数为39（30 - 53），精神维度为59（23 - 62）。视觉模拟评分（VAS）中位数为2（0 - 8）。
使用胫骨远端同种异体骨进行TTC融合显示出比其他结构性移植更低的塌陷率，并提供了与文献报道相当或更高的融合率。
四级，回顾性病例系列研究。
