Introduction Maximum radial bowing and its locations were studied based on normal anteroposterior (AP) radiograph of radius/ulna within the Malay ethnicity of Malaysians. Knowledge of radial bowing and its variation is beneficial when reconstructing radius. Material and Methods Radius AP bowing and its locations were assessed on 219 normal AP radiograph of radius/ulna in Picture Archiving and Communications System (PACS) that meet inclusion and exclusion criteria using the method of Schemitsch and Richards. Results The mean maximum radial bowing was 13.9mm (SD±2.11). The location of maximum bowing was 60.3% (SD±3.38) of the total radius length. The bow location was situated more distal in female (61.7% ±2.93) than male (59.7% ±3.88). However, males had more magnitude of radial bowing (14.7±1.84 vs 12.1±1.55) and longer length of total radius measurement (209.9±12.3 vs 188.1±12.2). In general, the left radius bowing location was situated proximally as compared to the right radius by 1% (59.8 ±3.4 vs 60.9 ±3.3). No significant differences were found for magnitude of maximum radial bow in between the left and right radius (14.0±2.1 vs 13.8±2.1). The total length of left radius was found to be 1.1mm longer than right radius (203.0±15.3 vs 201.9±15.9). Conclusion The mean maximal radial bowing and mean location of maximal radial bowing in the Malay ethnicity are 13.9±2.1mm and 60.3±3.4% respectively. These values are significantly higher in male as compared to female
