Abstract：
The tarsal navicular is an essential component of the Chopart joint and crucial for most of hindfoot motion. Most fractures are low-energy dorsal avulsions that may be treated nonoperatively. Displaced comminuted fractures require open reduction and internal fixation, sometimes with external fixation, bridge plating, and bone grafting. Diagnosis of stress fractures is commonly delayed. Conservative treatment is associated with good results, but surgery allows for quicker return-to-play in athletes. Nonunion in acute and stress fractures needs open debridement, grafting, and stable fixation. Müller-Weiss disease may present with a fragmented navicular and mimic an acute or a stress fracture.
摘要：
舟骨是Chopart关节的重要组成部分，对于大多数后足运动至关重要。大多数骨折是低能量的背侧撕脱，可以非手术治疗。移位的粉碎性骨折需要切开复位内固定,有时外固定，桥接电镀,和植骨。应力性骨折的诊断通常会延迟。保守治疗有良好的效果，但是手术可以让运动员更快地重返赛场。急性和应力性骨折的不愈合需要开放性清创术，嫁接,稳定的固定。Müller-Weiss病可能表现为舟骨破裂，并模仿急性或应力性骨折。
