Mid-term results of two different fixation methods for chevron osteotomy for correction of hallux valgus

We compared 2 different fixation methods (bioabsorbable pins and cannulated screws) after chevron osteotomy for the treatment of hallux valgus. We reviewed consecutive proximal chevron osteotomies in 80 patients (100 feet) performed by 2 surgeons. Of the 100 feet (80 patients), 48 feet (40 patients) were stabilized with bioabsorbable pins, and 52 feet (40 patients) were stabilized with cannulated screws. In the pin group. 8 patients were male (20%) and 32 were female (80%). In the screw group, 10 patients were male (25%) and 30 were female (75%). The mean patient age was 43.1 (range 24 to 60) years in the pin group and 43.5 (range 20 to 60) years in the cannulated screw group. The visual analog scale, intermetatarsal angle, and hallux valgus angle decreased significantly and the American Orthopaedic Foot and Ankle Society scores increased significantly in all patients in both groups after surgery (p<.05). No statistically significant differences were found between the 2 groups (p> .05). Both fixation methods were found to be safe and reliable under the appropriate conditions and when performed by an experienced surgeon.
