Sixty-nine Mitchell osteotomies augmented with smooth-pin fixation and a trapezoidal step-off osteotomy to maintain ray length were performed on 46 adolescent patients with a painful hallux valgus deformity. Average follow-up time was 6 years. By using radiographic, clinical, and subjective patient data, we found an overall excellent or good result in 91% of cases. Nine feet were found to be cosmetically unsatisfactory, 11 required special shoewear, 10 had mild residual pain with high heels or strenuous running, and three had pain severe enough to restrict activities. Range of motion was normal in 56 feet, slightly decreased in 11 feet, and significantly reduced in two feet. We conclude that, given a success rate of 91%, this slightly modified Mitchell osteotomy is a satisfactory procedure for adolescent hallux valgus deformity with chronic bunion discomfort.
对46例患有疼痛性拇外翻畸形的青少年患者进行了69次米切尔截骨术，术中采用光滑针固定和梯形台阶截骨术以保持跖骨长度。平均随访时间为6年。通过影像学、临床和患者主观数据，我们发现91%的病例总体结果为优或良。发现9只脚在外观上不尽人意，11只脚需要特殊鞋具，10只脚在穿高跟鞋或剧烈跑步时有轻度残留疼痛，3只脚疼痛严重到足以限制活动。56只脚的活动范围正常，11只脚略有下降，2只脚明显减小。我们得出结论，鉴于成功率为91%，这种略有改良的米切尔截骨术对于伴有慢性拇囊炎不适的青少年拇外翻畸形是一种令人满意的手术方法。
