Similar outcomes following scarf-Akin osteotomy compared to scarf-alone osteotomy for the treatment of hallux valgus: A systematic review and meta-analysis.

Background: The purpose of this systematic review and meta-analysis was to compare the clinical and radiographic outcomes between patients undergoing scarf osteotomy and scarf-Akin osteotomy for the management of hallux valgus deformity.
Methods: A systematic review of the MEDLINE, EMBASE and Cochrane Library databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting clinical data following scarf osteotomy and scarf-Akin osteotomy for the treatment of hallux valgus were included and assessed. The level and quality of evidence of the included studies were also evaluated.
Results: Four studies were included. In total, 388 patients (408 toes) underwent scarf osteotomy alone and 287 patients (295 toes) underwent scarf-Akin osteotomy for the treatment of hallux valgus deformity. There was no difference in postoperative American orthopedic foot and ankle society scores (p = 0.7828), visual analog scale scores (p = 0.4558), hallux valgus angle (p = 0.5116), intermetatarsal angle (p = 0.4830), proximal to distal phalangeal articular angle (p = 0.2411) between the scarf alone cohort and the scarf-Akin cohort. Similarly, there was no difference in complication rates (p = 0.6881) nor secondary surgical procedure rates (p = 0.3678) between the 2 cohorts. Finally, there was a higher recurrence rate in the scarf-alone cohort (11.4%) compared to the scarf-Akin cohort (5.7%), but this was not statistically significant (p = 0.4414).
Conclusion: This systematic review demonstrates lower recurrence rates following scarf-Akin osteotomy compared to scarf osteotomy alone for the treatment of hallux valgus deformity. No difference in complication rates were noted between the 2 cohorts. Our review demonstrates that both the scarf osteotomy and the scarf-Akin osteotomy may be effective and safe procedures, however, the scarf-Akin osteotomy may provide more long-term benefit in the setting of moderate to severe hallux valgus.
