In wrist pathology, there is a need to establish the normal range of radiographic measurement parameters. Previous study showed that the contralateral wrist might not be valid as a reference for all parameters. There is a lack of literature describing the normal range of wrist radiographic parameters in literature. As a result, a retrospective study was carried out. Patients who underwent standard wrist x-rays during the period February 2012 to February 2013 (one single year) were retrospectively reviewed. 71 patients were included. Scapholunate angle was 54.7° (±6.5°). Scapholunate interval was 2.0 mm (±0.4 mm). Ulnar variance was +1.0 mm (±1.8 mm). Carpal height was 31.8 mm (±3.0 mm). Radial inclination was 25.1° (±2.1°). All 71 patients had 1 sesamoid bone at first metacarpal. 16.9% (12 out of 71) patients had positive cortical ring signs. All these parameters are valuable clinically, especially in monitoring of the wrist disease progression, in the design of wrist implants and for future clinical research.
