Congenital or acquired shortness of a metatarsal may cause pain in adjacent metatarsals. From 1983 to 1990, we performed nine metatarsal lengthenings in seven adolescent patients by metaphyseal osteotomy followed by gradual distraction of callus (callotasis). Two patients required bone grafts after the lengthening. We used a rigid, unilateral external fixator designed for use in the hand and foot. At follow-up, from three to ten years later, healing had been achieved in all with an average healing index of 50 days/cm, and metatarsalgia had been relieved by the restoration of correct metatarsal length.
先天性或后天性跖骨短小可能导致相邻跖骨疼痛。1983年至1990年，我们对7例青少年患者进行了9次跖骨延长手术，采用干骺端截骨术，随后逐渐牵张骨痂（骨痂延长术）。2例患者延长后需要植骨。我们使用了一种专为手足设计的坚固单侧外固定器。随访时，3至10年后，所有患者均已愈合，平均愈合指数为50天/厘米，通过恢复正确的跖骨长度，跖痛症得到缓解。
