Abstract：
A man in his early 70s with right Takakura stage IIIB varus ankle osteoarthritis underwent medial opening wedge supramalleolar osteotomy with inframalleolar correction as joint preserving procedure. We also performed anteroinferior tibiofibular ligament (AITFL) resection with fibular shortening valgisation osteotomy to enhance the talar tilt correction. Postoperative decrease in talar tilt with dramatic symptom improvement was achieved. Performing the AITFL resection with fibular shortening valgisation osteotomy plus concomitant supramalleolar osteotomy and inframalleolar correction for Takakura stage IIIB varus ankle osteoarthritis resulted in successful improvement in talar tilt by making room for the valgus deviation of the talus.
摘要：
一名70年代初患有右高仓III期内翻踝关节骨关节炎的男子接受了内侧开放楔形踝上截骨术和踝下矫正作为关节保留手术。我们还进行了下胫腓前韧带（AITFL）切除术和腓骨缩短术，以增强距骨倾斜矫正。术后距骨倾斜减少，症状明显改善。TakuraIIIB期内翻踝关节骨关节炎进行AIFL切除术，并伴有踝上截骨术和踝下矫正，通过为距骨外翻提供空间，成功改善了距骨倾斜。
