Distal tibial malalignment can result from posttraumatic malunion, physeal disturbances, congenital or metabolic diseases, and degenerative arthritis. Malalignment leads to an altered load distribution across the joint leading to early ankle joint arthritis. If a substantial part of the joint is salvageable, ankle fusion or joint replacement is not always the best option. Realignment of the distal tibia with a joint-sparing supramalleolar osteotomy is a valuable procedure in correcting deformity at the distal tibia. The goal of a supramalleolar osteotomy is to restore axial alignment. Several studies have demonstrated the successes of the osteotomy in improving function and relieving pain.
胫骨远端对线不良可由创伤后畸形愈合、骨骺紊乱、先天性或代谢性疾病以及退行性关节炎引起。对线不良会导致关节负荷分布改变,进而引发早期踝关节关节炎。如果关节的大部分结构可挽救,踝关节融合术或关节置换术并不总是最佳选择。采用保留关节的距上截骨术对胫骨远端进行重新对线,是纠正胫骨远端畸形的一种有效方法。距上截骨术的目的是恢复轴向对线。多项研究已证明该截骨术在改善功能和缓解疼痛方面取得了成功。
