The influence of the number of screws and additional surgical procedures on outcome in hallux valgus treatment

Table 3 Characteristics of cases treated with reversed L-shaped osteotomy (ReveL) for hallux valgus deformity using one or two screws and their association with secondary outcome variables (n = 799)

Abbreviations: N number, % percent, OR odds ratio, CI confidence interval
^*Wald test
^†Limited patient satisfaction was defined as dissatisfied or improved, while patient satisfaction was defined as satisfied or very satisfied
^‡Adjusted for potential confounders and effect modifiers: age, sex, body mass index, additional surgical technique for hallux valgus, preoperative hallux valgus angle, and time period
^§Defined as infection, osseous necrosis, non-union, complex regional pain syndrome, and revision
^‖Adjusted for potential confounders and effect modifiers: age, sex, body mass index, additional surgical technique for hallux valgus, concomitant diseases, bilateral surgery, preoperative hallux valgus angle, preoperative distal metatarsal angle, and time period (n = 753 due to collinearity)
