SECONDARY
We compared the baseline characteristics and functional outcome at 7 months and at 7.5 years between the included patients and those lost to follow-up to rule out potential effects of attrition. Long-term results of primary and secondary outcomes were compared between the 2 groups (AEC vs. BEC) using independent T-testing and crosstabs. Results are presented as mean with 95% confidence interval (CI) and standard deviation (SD) because of normal distribution. Furthermore, to address the issue of missing data, linear mixed-model analyses were done for the primary outcome to compare the between-group differences over the different time points where means with 95% CI are presented.We performed a subgroups analysis for both groups on loss of forearm rotation. The pronation and supination were scaled using the grading system as described by Daruwalla with excellent, good, fair, and poor results for, respectively, 0–10°, 11–20°, 21–30°, and ≥ 31° of limitation [
