The primary outcome was the Patient-Reported Wrist Evaluation (PRWE) score between the study groups at 24 months. Secondary outcomes were differences in means in the short version of Disabilities of arm, shoulder and hand, Quick-DASH score (qDASH, gives a scale from 0 to 100), visual analogue scale of pain (VAS, scale from 0 to 100 mm), health-related quality of life (15D, scale from 0 to 1), number of complications, number of surgical interventions, number of cast changes, and differences in the costs of the treatment. The PRWE is a 15-item questionnaire designed to measure wrist pain and disability in activities of daily living, MacDermid et al. [In power calculations, we determined the required sample size per group to be 40 patients. This calculation was done by using the primary outcome variable (PRWE) with 95% confidence interval, power of 0.95, and SD of 14. Thus, to have enough statistical power, 40 patients in both groups had to complete 2-year follow-up.
