Correction of moderate to severe hallux valgus deformity by a modified chevron shaft osteotomy



Correction of moderate to severe hallux valgus deformity by a modified chevron shaft osteotomy



Foot and Ankle International 27(8): 581-585



Hallux valgus is one of the most common foot deformities in women. Despite the large number of techniques described for hallux valgus correction, there has been much controversy regarding the best procedure to use, especially for severe deformities. Proximal osteotomies have long been done for severe deformities; however, diaphyseal osteotomies have gained popularity because of the greater degree of correction and stability obtained. This study retrospectively assessed the radiographic and clinical outcomes in 50 feet (34 patients) that had a modified chevron shaft osteotomy for moderate to severe hallux valgus. Additionally, an Akin medial closing wedge osteotomy of the proximal phalanx was done in most patients. Mean followup was 30 months (minimum 13 months). All patients in the study had either moderate or severe deformities. Patients with mild deformities had correction by other techniques. There was a mean AOFAS score improvement of 39.6 (44.5 to 84.1) points. The hallux valgus angle and intermetatarsal angle improved a mean of 22.7 degrees and 10.4 degrees, respectively. Hallux valgus persisted in one foot; however, the patient was not dissatisfied. Two feet developed hallux varus. Revision was necessary in two patients; one needed revision because of loss of fixation and the other because of symptomatic hallux varus. Based on radiographic correction and clinical outcomes, this procedure is indicated for the treatment of moderate to severe hallux valgus deformities.
