Aim. A prospective randomized study was performed to compare two different fixation methods for distal Chevron (Austin) osteotomy for correction of hallux valgus deformities. Methods. Between June 2004 and January 2005, 22 patients were included in this study using precise criteria (age<60 years, intermetatarsal angle<16°, pain related to the hallux valgus deformity, a mobile and smooth metatarsophalangeal joint, no previous surgery or other different deformities). The patients were randomized into two groups, homogeneus for number, in relation to the type of fixation: Group A: fixation with Kirschner wires (1,8 mm); Group B: fixation with Herbert screw (2,7mm). Results. All the patients were clinically and radiographically evaluated at 1,3 and 6 months from surgery. Clinical evaluation was performed using the Hallux Score of the American Orthopedic Foot and Ankle Society (AOFAS). At six months, it was respectively 94,09 for Group A and 94,45 for Group B (p>0,05) showing no significant differences between the two fixations methods. Conclusion. Leaving out the economical side, the surgeon should make his choice on the base of his experience and his familiarity towards one or the other fixation method.

Abstract
Aim. A prospective randomized study was performed to compare two different fixation methods for distal Chevron (Austin) osteotomy for correction of hallux valgus deformities. Methods. Between June 2004 and January 2005, 22 patients were included in this study using precise criteria (age<60 years, intermetatarsal angle<16°, pain related to the hallux valgus deformity, a mobile and smooth metatarsophalangeal joint, no previous surgery or other different deformities). The patients were randomized into two groups, homogeneus for number, in relation to the type of fixation: Group A: fixation with Kirschner wires (1,8 mm); Group B: fixation with Herbert screw (2,7mm). Results. All the patients were clinically and radiographically evaluated at 1,3 and 6 months from surgery. Clinical evaluation was performed using the Hallux Score of the American Orthopedic Foot and Ankle Society (AOFAS). At six months, it was respectively 94,09 for Group A and 94,45 for Group B (p>0,05) showing no significant differences between the two fixations methods. Conclusion. Leaving out the economical side, the surgeon should make his choice on the base of his experience and his familiarity towards one or the other fixation method.
