Brachymetatarsia is not an uncommon congenital foot disorder that is due to a premature closure of the ephiphyseal plate. The literature has numerous surgical procedures for the correction of this problem. In recent years, the callus distraction technique described by ilizarov has been utilized for this problem. This is a retrospective study of the use of the callus distraction technique for the correction of congenitally short metatarsal. This series included six feet in six female patients, all with a short fourth metatarsal. Preoperative complaints were metatarsalgia and/or cosmesis. A noncircular, uniplanar axial fixation device was utilized for fixation and distraction. The fixator was put in place prior to the metatarsal osteotomy. Static fixation was for a period of 5-7 days before distraction was begun. The metatarsal was lengthened 0.5 mm two times a day, or 1 mm per day. The time to end point ranged from 45 to 70 days, followed by another 6-8 weeks of static immobilization. The preoperative metatarsal length ranged from 3.5 to 4.2 cm. The end stage metatarsal length ranged from 4.7 to 6.3 cm, with an average increase in length of 1.68 cm. As compared to other techniques described in the medical literature, the callus distraction technique has its own unique set of advantages and disadvantages.
短跖骨症是一种并不罕见的先天性足部疾病，是由于骨骺板过早闭合所致。文献中有众多用于矫正该问题的外科手术方法。近年来，伊利扎洛夫描述的骨痂牵张技术已被用于解决此问题。这是一项关于使用骨痂牵张技术矫正先天性短跖骨的回顾性研究。该系列包括6例女性患者的6只脚，均为第四跖骨短小。术前主诉为跖痛和/或美观问题。使用非圆形、单平面轴向固定装置进行固定和牵张。在跖骨截骨术前放置固定器。在开始牵张前进行5 - 7天的静态固定。跖骨每天延长0.5毫米，分两次进行，即每天延长1毫米。达到终点的时间为45至70天，随后再进行6 - 8周的静态固定。术前跖骨长度为3.5至4.2厘米。最终阶段跖骨长度为4.7至6.3厘米，平均长度增加1.68厘米。与医学文献中描述的其他技术相比，骨痂牵张技术有其独特的一系列优缺点。
