ABSTRACT

Brachymetatarsia is a congenital or acquired malformation, which includes an abnormal shortening of one or more metatarsals. The objective of this study was to evaluate the functional and radiographic results of surgical treatment in congenital brachymetatarsia with lengthening osteotomy and use of external fixation. Material and methods: A retrospective, descriptive, cross-sectional and analytical study was conducted at the Shriners Hospital for Children, Mexico City, between January 2011 and December 2014. Patients from 10 to 18 years of age with congenital brachymetatarsia, aesthetic disagreement, complete functional and radiographic evaluation of the affected foot, undergoing progressive distraction with external minifixation of the affected metatarsal, with a minimum follow-up of five years were included. For the functional evaluation, the MOXFQ questionnaire was used. For the radiographic evaluation, the elongated millimeters, the consolidation time in each affected metatarsal were taken into account, without obviating the complications obtained. Results: 14 patients were included, 23 affected metatarsals; 1 man (8%) and 13 women (92%). The average age was 14 years old. In 69% both feet were affected, 22% right foot and 9% left foot. The fourth metatarsal was the most affected. The three sections evaluated in the MOXFQ questionnaire improved by more than 50%, with greater predominance in the category of social interaction. Radiographic evaluation showed a growth rate of 40% with an average consolidation time of 16 weeks. Both statistically significant evaluations. Eight patients presented complications (34%). Conclusion: The lengthening and external fixation osteotomy continues to be effective as a therapeutic option for brachymetatarsia, obtaining in this work, improvement of functional and radiographic results after treatment with statistically significant results. The percentage of complications found were similar to that reported in other studies despite having a high average growth rate.
