The midtarsal joint, also known as the Chopart or the transverse tarsal joint, is composed of the talonavicular and calcaneocuboid articulations. Midtarsal joint dislocations are rare injuries given the strong periarticular ligamentous support.2, 3 Medial, lateral, dorsal, and rarely plantar dislocations have been reported from multiple high-energy mechanisms.4, 5 We describe the case of a 24-year-old male who sustained talonavicular and calcaneocuboid plantar dislocations associated with a middle and lateral intercuneiform dislocation, open proximal 5th metatarsal fracture, 2nd-4th metatarsal base fractures, and lateral cuneiform fracture. The mechanism of injury, diagnosis, management, operative intervention, and follow up are discussed.
中跗关节，也称为Chopart关节或横跗关节，由距舟关节和跟骰关节组成。鉴于关节周围有强大的韧带支持，中跗关节脱位是罕见的损伤。2, 3 已有报道称，多种高能机制可导致内侧、外侧、背侧脱位，足底脱位则较为罕见。4, 5 我们描述了一名24岁男性的病例，该患者发生了距舟关节和跟骰关节足底脱位，并伴有中楔骨和外侧楔骨间脱位、第5跖骨近端开放性骨折、第2 - 4跖骨基底骨折以及外侧楔骨骨折。本文讨论了损伤机制、诊断、治疗、手术干预及随访情况。
