 After obtaining institutional review board IRB approval, the investigators performed this prospective randomized clinical trial on patients with DRFs admitted in three medical centers from September 2010 to February 2011. Patients signed the consent form prior to enrolment. the investigators included the patients older than 20 years with closed distal radial physis and initial radiographic evidence of extra articular DRF with at least one non-comminuted cortex. All fractures were type A2 according to the AO classification. The investigators considered fractures with dorsal angulations of more than 20 degrees, radial shortening of more than 10 millimeters and extensive cortical comminution as unstable fractures. Patients with unstable fractures were excluded from this study. Other exclusion criteria were the existence of multiple fractures or open fracture in the affected limb or other limbs, cerebral palsy, paresthesia of the affected limb due to the pervious cerebro-vascular accidents, previous severe deformity of the affected limb, diabetes and severe osteoporosis. Th investigators also excluded patients who had less than two consecutive follow-up visits. All eligible patients signed the informed consent. One hundred four patients were eligible to be included in this study; The investigators excluded four patients, as they did not tend to participate in the process of follow-up. The investigators divided 100 remaining patients into reduction with SAC or reduction with LAC groups based on the table of random numbers.
