Abstract

This case report demonstrates a unique variant of a Chopart dislocation resulting in a plantar cuboid and navicular dislocation without concomitant fracture in a 48-year-old man. The mechanism of injury involved a low-energy plantarflexion moment from stepping off a small embankment. This report reviews the pertinent midfoot anatomy, discusses the proposed mechanism of injury, and demonstrates an effective method of treating these complex injuries with open reduction and internal fixation. Final results with 20 months of follow-up were excellent. This unusual midfoot dislocation is a complex injury that required open treatment for anatomic restoration. In complex Chopart dislocations, early open reduction should be strongly considered as the initial treatment to properly restore anatomy and function. Level of Evidence: Level V, expert opinion.

摘要

此病例报告显示了Chopart脱位的独特变体，导致48岁男性的足底长方体和舟骨脱位而没有伴随骨折。损伤的机制涉及从小路堤上走下来的低能量足底弯曲时刻。本报告回顾了相关的中足解剖结构，讨论了拟议的损伤机制，并证明了通过切开复位和内固定治疗这些复杂损伤的有效方法。经过20个月的随访，最终结果非常好。这种不寻常的中足脱位是一种复杂的损伤，需要进行开放式解剖修复。在复杂的肖帕特位错中，早期切开复位术应被视为正确恢复解剖结构和功能的初始治疗。证据级别：V级，专家意见。
