Objective. Te purpose of this retrospective study was to compare the clinical and radiological results of magnesium versus titanium screw fxation for modifed distal chevron osteotomy in hallux valgus (HV). Materials and Methods. A total of 31 patients who underwent modifed distal chevron osteotomy for HV deformity between 2014 and 2017 were reviewed retrospectively. Headless magnesium (Mg) compression screw fxation was applied in 16 patients (17 feet) and headless titanium (Ti) compression screw in 15 patients (17 feet). Patients were followed up for at least 12 months with a mean of 19.0 ± 6.8 months in the Mg screw group and 16.2 ± 6.19 in the Ti screw group, respectively (p: 0.234). Clinical results were evaluated using the American Orthopedic Foot and Ankle Society Hallux metatarsophalangeal-interphalangeal (AOFAS-MTP-IP) scale and a visual analogue scale (VAS). Te hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured before and afer surgery. Time to osteotomy union and any complications were recorded and compared between the groups. Results. An improvement in the AOFAS-MTP-IP scale and VAS points were recorded in both groups with no statistically signifcant diference between the groups (p: 0.764 and 0.535, resp.). At the fnal follow-up examination, HVA and IMA were similar (p: 0.226 and 0.712, resp.). Tere was no signifcant loss of correction between the early and fnal radiographs in respect of HVA and IMA in both groups (p: 0.321 and p: 0.067). Full union of the osteotomy was obtained in all patients. Prolonged (1.5 months) swelling and mild hyperemia around the surgical incision were observed in 1 patient in the Mg group but there was a good response to physical and medical therapy, and the complaints were completely resolved. Tere were no other signifcant complications in either group. Conclusion. Te results of this study showed that bioabsorbable Mg compression screw fxation has similar therapeutic efcacy to Ti screw fxation in respect of functional and radiological outcomes. Bioabsorbable Mg screw is an alternative fxation material that can be safely used for modifed distal chevron osteotomy in HV surgery. 1. Introduction Hallux valgus (HV) is a common foot deformity that may cause pain, disability, difculty in shoe wear, and gait dis- turbance. Initially, a period of conservative care can be tried but if the symptoms are not relieved and the deformity has progressed, surgical correction is usually necessitated. More than 300 surgical procedures have been described over the years for the correction of HV deformity [1]. Te decision-making process for HV surgery depends on the severity of the deformity determined by the clinical fndings and radiological measurements. Currently, distal metatarsal chevron osteotomy is commonly used for the correction of mild-to-moderate HV deformities with a congruent metatar- sophalangeal (MTP) joint [2]. Te technique for a distal chevron osteotomy was initially described by Austin and Leventen without performing an osseous fxation [3]. Tese authors thought that the three- dimensional confguration of the osteotomy was inherently stable and additional medial capsulorrhaphy provided fur- ther stability. Subsequently several modifcations have been made to the technical part of the procedure, including the angle of the osteotomy and the use of various alternative methods of internal fxation [4].
