Talar osteonecrosis is a well-described phenomenon following talar neck fracture, but is a rarely described complication after procedures about the foot and ankle. Here we describe the clinical course of 5 cases of talar osteonecrosis following injection of calcium phosphate into the talus (subchondroplasty) with or without acute lateral ligament repair after acute lateral ankle ligament injuries performed at an outside institution. Practitioners should be aware of this potentially devastating complication. Future research is indicated to determine the safety and efficacy of subchondroplasty for the talus.

距骨坏死是距骨颈骨折后一种广为人知的现象，但在足踝部手术之后却是一种鲜有描述的并发症。在此，我们描述了5例距骨坏死的临床病程，这些病例是在外部机构进行急性外侧踝关节韧带损伤修复时，向距骨注射磷酸钙（软骨下成形术），无论是否同时进行急性外侧韧带修复。从业者应意识到这种潜在的严重并发症。需要开展进一步研究以确定距骨软骨下成形术的安全性和有效性。
