Midterm outcome after correction of hallux valgus deformity using scarf osteotomy in adult population

Context: Determining the efficacy of any surgical treatment is the key to achieve better practice and best outcomes for patients. Aims: This study is designed to address midterm outcome in adult patients with moderate-to-severe hallux valgus (HV), who underwent scarf osteotomy from 2012 to 2014. Settings and Design: This is a retrospective cohort study in which charts of all adult patients with moderate-to-severe HV who underwent scarf osteotomy from 2011 to 2014 were reviewed. Subjects and Methods: Between 2011 and 2014, 39 patients (41 feet) who underwent scarf osteotomy for correction of HV deformity were retrospectively evaluated. Standard weight-bearing dorsoplantar radiographs were obtained pre- and postoperatively. HV angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angles (DMAA) were measured pre- and postoperatively to evaluate the efficacy of the surgery. The complication rate was reported. The average follow-up was 13.5 months, and the patients' mean age was 37 years. Statistical Analysis Used: Data were compared using Chi-square test or Fisher's exact test whichever was appropriate. All tests were two-sided, and a P> 0.01 was considered statistically significant. Results: The average preoperative HVA and IMA were 32° and 14.3°, which improved to 11° and 7.9°, respectively. The changes were statistically significant (P < 0.01). The average DMAA was 16° which was reduced to (12°); however, the change was not statistically significant (P > 0.18). Conclusions: This study suggests that scarf osteotomy surgery is a very versatile osteotomy in correcting moderate-to-severe HV deformity. It offers a greater degree of correction and stability, lower rate of complications and good outcome. However, long-term follow-up studies are still needed.
