The data are given as the mean and the standard deviation or as the number of patients, with the percentage in parentheses.
Pin-site infections were not included as superficial surgical site infections (SSIs).
Thirteen individuals had malalignment at 1 year, of whom 4 had biplanar deformity.
Secondary outcomes were compared between treatment groups at 1 year with use of the Student t test.
The EQ-5D-3L index measures health-related quality of life.
VAS = visual analog scale.
mRUST = modified Radiographic Union Scale for Tibial fractures.
