Resumo
Results of biplanar chevron osteotomy performed on patients with mild-to-moderate hallux valgus deformity with an increased distal metatarsal articular angle (DMAA) are shown. The study included clinical data of 32 patients (54 feet) who had completed a 2-year follow-up, and radiological data of these 32 and other 29 patients (50 feet) for a total of 61 patients (104 feet, 53 right and 51 left). There were 59 females and two males with ages varying from 11 to 66 years. According to the AOFAS Hallux Rating, the preoperative average score (50) Improved to 90 (average score after the surgery). The hallux valgus angle was improved from an average of 250 to 14degrees, the first intermetatarsal angle from 12degrees to 8degrees and the DMAA from 15degrees to 5degrees. At the end of treatment, 94% of patients were classified as having grade 0 or 1 sesamold lateral sub-luxation. Given improvement in angles and 90% of patients satisfied with an average AOFAS postoperative score of 90, the technique seems indicated for treatment of symptomatic hallux valgus deformity with increased DMAA.
