Purpose: This study compared the radiographic and clinical outcomes of simultaneous bilateral short scarf osteotomy with those of unilateral short scarf osteotomy in hallux valgus patients.
Materials and Methods: The authors undertook a retrospective chart and radiographic review between January 2015 and June 2017 to identify 15 patients (30 cases, group A) who underwent a simultaneous bilateral short scarf osteotomy. The patients were matched with 30 patients (30 cases, group B) with a unilateral short scarf osteotomy. No significant preoperative differences were observed between the two groups in terms of age, gender, American Orthopaedic Foot and Ankle Society (AOFAS) hallux score, and radiographic parameters. The clinical and radiographic follow-up was carried out at three months and one year.
Results: Hallux valgus angles in groups A and B were reduced from the mean preoperative values of 32.5° and 34.7° to 12.5° and 12.2° at 12 months, respectively. The first-second intermetatarsal angles in groups A and B were also reduced from the mean preoperative values of 14.2° and 16.5° to 7.4° and 7.3° at 12 months, respectively. No significant inter-group differences in radiographic outcomes were observed. After three months, the patients in group A reported significantly worse mean pain and functional scores than group B. The mean AOFAS hallux score was higher in group B at the three-month follow-up, but this difference disappeared at the one-year follow-up.
Conclusion: Simultaneous bilateral surgery can be offered to patients with a hallux valgus deformity requiring correction. On the other hand, they should be informed of the long recovery period.
