To describe the profile of the patients and the results obtained with the use of an external fixator for metatarsal lengthening in brachymetatarsia. A retrospective analysis of the medical records of patients with brachymetatarsia treated between January 2018 and April 2020 was performed. During this period, eight feet of six patients were operated on. Frequencies were estimated according to demographic and surgical aspects. All patients (100%; = 6) were female, with a mean age of 28 years old, ranging from 15 to 48 years old, and were motivated to seek the orthopedic service due to aesthetic deformity. The deformity was bilateral in two patients and unilateral in four patients. The average lengthening time was 22 days ( ± 7.15, 95% confidence interval [CI]: 19.04-26.81). The lengthening speed was 0.5 mm/day, and the average total length of the lengthening was 11.46 mm ( ± 3.57; 95%CI: 9.52-13.40). Half of the patients (50%; = 3) had local infection of the pins and were treated with antibiotics, and the others did not report any postsurgical complications. All patients denied pain or calluses after the surgical procedure and reported satisfaction with the results. All patients were female and sought surgery for brachymetatarsia for aesthetic reasons. Osteogenic distraction at a rate of 0.5 mm/day resulted in successful lengthening of the metatarsal, with a low frequency of complications, good clinical outcomes, and high patient satisfaction.
描述短跖症患者的特征以及使用外固定器进行跖骨延长术的结果。 对2018年1月至2020年4月间接受治疗的短跖症患者的病历进行回顾性分析。在此期间，对6例患者的8只脚进行了手术。根据人口统计学和手术方面的情况估算频率。 所有患者（100%；n = 6）均为女性，平均年龄28岁，年龄范围为15至48岁，因美观畸形而主动寻求骨科治疗。两名患者为双侧畸形，四名患者为单侧畸形。平均延长时间为22天（±7.15，95%置信区间[CI]：19.04 - 26.81）。延长速度为0.5毫米/天，平均总延长长度为11.46毫米（±3.57；95%CI：9.52 - 13.40）。一半的患者（50%；n = 3）出现了钢针局部感染，接受了抗生素治疗，其他患者未报告任何术后并发症。所有患者在手术后均否认疼痛或胼胝形成，并对结果表示满意。 所有患者均为女性，因美观原因寻求短跖症手术治疗。以0.5毫米/天的速度进行成骨牵引导致跖骨成功延长，并发症发生率低，临床效果良好，患者满意度高。
