Abstract

Objective To describe the profile of the patients and the results obtained with the use of an external fixator for metatarsal lengthening in brachymetatarsia.

Methods 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.

Results All patients (100%; n = 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%; n = 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.

Conclusion 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.
