What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
wrist motion range	extension, flexion, radial deviation, ulnar deviation, forearm pronation and forearm supination	3 months, 6 months, and 1 year
ulnar sided pain	presence of ulnar-sided wrist pain during daily activities was recorded	3 months, 6 months, and 1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
radiographic analysis	Standard anterior-posterior and lateral radiographs were obtained at each time point to evaluate fracture healing and the alignment of the distal part of the radius. Radial inclination, volar tilt, and radial height were measured	6 weeks, 3 months, and 1 year
