Chevron bunionectomy with microplate and screw fixation: a retrospective follow-up of 26 feet.

The authors report the results of 21 patients (26 feet) who had Chevron osteotomy of the first metatarsal head to correct hallux valgus. Fixation was achieved by using a small plating system consisting of one L-plate (8.5 mm x 17 mm x 0.8 mm) and four screws (1.6 mm). Results showed no capital fragment displacement, avascular necrosis, or plate deformation. One case of screw loosening was noted on x-rays. This patient noted occasional irritation over the plate while wearing shoes. Symptoms did not cause the patient to seek removal of the plate and screws. The small plate system allows the surgeon to perform the osteotomy as originally described by Austin, with the added security of rigid internal fixation.
