Twelve patients who had a total of 18 Mitchell bunionectomies were reviewed to assess the long-term results of the procedure. Although metatarsus varus correction was maintained in all cases, hallux valgus recurred in 11 of the 18 cases. Sixty-seven percent reported complete relief or improvement of preoperative pain. Although lateral metatarsalgia did occur, the most common area of persistent pain remained the first metatarsal. Six of 18 procedures had marked loss of active joint motion, associated with pain and an unsatisfactory result. Of 18 procedures, 11 (61%) were satisfied with the results of their osteotomy. Although the Mitchell osteotomy corrected the metatarsus primus varus in each case, the current series shows a discouraging incidence of later recurrence of hallux valgus and restriction of metatarsophalangeal motion causing the abandonment of this procedure for the management of juvenile bunion.
对12例患者共18次米切尔拇囊炎切除术进行了回顾，以评估该手术的长期效果。尽管所有病例均维持了内翻畸形的矫正，但18例中有11例拇外翻复发。67%的患者报告术前疼痛完全缓解或改善。虽然确实出现了外侧跖痛，但持续疼痛最常见的部位仍然是第一跖骨。18例手术中有6例出现明显的主动关节活动丧失，伴有疼痛且结果不理想。18例手术中，11例（61%）对截骨术的结果满意。尽管米切尔截骨术在每种情况下都矫正了第一跖骨内翻，但目前的系列研究显示，拇外翻后期复发以及跖趾关节活动受限的发生率令人沮丧，导致该手术不再用于治疗青少年拇囊炎。
