Fracture of the os peroneum is rare, and displacement of the fracture can be indicative of a tear in the peroneal longus tendon. A fifth metatarsal base fracture is a common injury caused by sudden inversion and plantar flexion of the hindfoot. We observed a rare case of a fifth metatarsal base zone I fracture combined with a displaced os peroneum fracture in a 34-year-old woman. The patient was treated with resection of the os peroneum and repair of the peroneal longus tendon, as well as open reduction and internal fixation of the fifth metatarsal base. After exposing the fragment of the fifth metatarsal base, the distal part of the fractured os peroneum was found to be located just under the fracture site. There were no complications or discomfort of the foot or ankle at 2 years postoperatively. Resection of the os peroneum and direct repair of the peroneal longus tendon were easily performed after the fifth metatarsal base fragment was exposed. This was an innovative method for performing peroneal longus tendon repair in the deep portion of the midfoot.
距骨后突骨折很少见，且骨折移位可能提示腓骨长肌腱撕裂。第五跖骨基底部骨折是一种常见的损伤，由后足突然内翻和跖屈引起。我们观察到一例 34 岁女性罕见的第五跖骨基底部 I 区骨折合并距骨后突骨折。该患者接受了距骨后突切除和腓骨长肌腱修复，以及第五跖骨基底部切开复位内固定治疗。暴露第五跖骨基底部骨折块后，发现骨折的距骨后突远端刚好位于骨折部位下方。术后 2 年，足部和踝关节无并发症或不适。在暴露第五跖骨基底部骨折块后，很容易进行距骨后突切除和腓骨长肌腱直接修复。这是一种在中足深部进行腓骨长肌腱修复的创新方法。
