6 women with brachymetatarsia involving 9 bones were treated by the use of the Ilizarov semicircular lengthener. The affected bones were the second, third and fourth metatarsals. Ilizarov half-rings were applied on the foot with 5 or 6 half-pins (3 mm in diameter) and a percutaneous osteotomy was done. The short metatarsals were lengthened 0.25 mm twice a day by the patient. The lengthened distance was 15 (10-22) mm and the overall treatment time was 15 (12-25) weeks. The postoperative course was uneventful, with smooth bone regeneration. No bone-grafting was needed. During treatment, the patients could bear full weight and tolerated the fixators well. We conclude that this technique is useful in the treatment of brachymetatarsia.
6名患有短跖骨症且累及9根骨头的女性患者采用Ilizarov半圆形延长器进行治疗。受累骨头为第二、第三和第四跖骨。在足部应用Ilizarov半环，使用5或6枚半针（直径3毫米），并进行经皮截骨术。短跖骨由患者每天延长0.25毫米两次。延长距离为15（10 - 22）毫米，总治疗时间为15（12 - 25）周。术后过程顺利，骨再生良好。无需植骨。治疗期间，患者可完全负重，对固定器耐受性良好。我们得出结论，该技术在治疗短跖骨症方面有用。
