Abstract

Tarsometatarsal (Lisfranc) fracture-dislocations can be very difficult to recognize radiographically. The evaluation of the Lisfranc joint can be simplified by meticulously studying the alignment of the metatarsal bases with their corresponding tarsal bones. The usefulness of this observation has been confirmed by: anatomic descriptions, biomechanical analysis, and clinical foot radiographs. Subtle abnormalities identified at the Lisfranc joint using this observation included: metatarsal subluxations identified only on a single projection, associated tarsal subluxations and dislocations, irreducible metatarsal subluxations after closed manipulation, and recurrent metatarsal subluxations after reduction.

摘要

跗跖关节（Lisfranc）骨折脱位在X线片上可能很难识别。通过仔细研究跖骨基底与其相应跗骨的对线情况，可简化对Lisfranc关节的评估。这一观察结果的实用性已通过以下方面得到证实：解剖学描述、生物力学分析以及足部临床X线片。使用这一观察方法在Lisfranc关节发现的细微异常包括：仅在单一投照位上发现的跖骨半脱位、相关的跗骨半脱位和脱位、闭合手法复位后不可复位的跖骨半脱位以及复位后复发性跖骨半脱位。
