According to the reduction technique of the dorsal ulnar fragment, the patients were divided into the conventional reduction (CRG) group (33 patients, 14 males and 19 females, mean age 57.2\u2009\u00b1\u200912.1\u2009years old) and the \u201cpoking reduction\u201d (PRG) group (45 patients, 11 males and 34 females, mean age 60.1\u2009\u00b1\u200912.4\u2009years old). According to the AO classification, there were 21 cases of C3.1 and 12 of C3.2 in the CPG group, 27 cases of C3.1 and 18 of C3.2 in the PRG group. Clinical and radiographic data were extracted from the electronic medical record system. These data were reviewed for clinical outcomes (range of motion, grip strength), radiological outcomes (volar tilt, radial inclination, radial height, step of articular surface), and postoperative complications.
