Treatment of brachymetatarsia using a semicircular lengthener. 1-3 years results in 6 patients.
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.
