The complete loss of articular relationships between the talus and navicular bone is known as talonavicular joint (TNJ) dislocation. Medial dislocation of the TNJ is more common than lateral dislocation. Lateral dislocation is usually associated with a fracture of the calcaneocuboid joint. Surgeons encounter difficulties when treating these dislocations. It occurs following high-energy trauma and is managed with immediate closed reduction of the joint and immobilization, but some complicated cases require open reduction and fixation to achieve alignment, strength, and function. This case report describes a six-month-old neglected case of TNJ dislocation managed with corrective osteotomy and subtalar fixation. Fusion of the talonavicular and talocalcaneal joints was performed. This procedure had a satisfactory outcome, as the patient was completely relieved of pain.
距骨与舟状骨之间关节关系完全丧失被称为距舟关节（TNJ）脱位。TNJ内侧脱位比外侧脱位更常见。外侧脱位通常与跟骰关节骨折相关。外科医生在治疗这些脱位时会遇到困难。它发生于高能创伤后，通过立即进行关节闭合复位和固定来处理，但一些复杂病例需要切开复位和固定以实现对线、强度和功能。本病例报告描述了一例六个月大被忽视的TNJ脱位病例，采用矫正截骨术和距下固定进行治疗。同时进行了距舟关节和距跟关节融合术。该手术取得了满意的效果，患者疼痛完全缓解。
