Brachymetatarsia is not an unusual deformity and is often associated with functional and cosmetic issues that warrant surgical reconstruction. Lengthening of the affected metatarsal can be undertaken on an acute basis in a single operative procedure that involves the use of a bone graft or by means of gradual callus distraction. Because of the risk of metatarsophalangeal joint malalignment, it is important for the surgeon to take steps to stabilize the joint during the lengthening process. In this report, a percutaneous method of callus distraction for repair of brachymetatarsia and maintenance of metatarsophalangeal joint alignment is presented.
短跖畸形并不罕见，常伴有功能和美观问题，需要进行手术重建。可通过单次手术急性延长受累跖骨，该手术涉及使用骨移植或通过逐渐的骨痂牵张进行。由于存在跖趾关节排列不齐的风险，外科医生在延长过程中采取措施稳定关节很重要。在本报告中，介绍了一种经皮骨痂牵张方法，用于修复短跖畸形并维持跖趾关节对齐。
