Methods The standard X-ray radiography was used to measure the positive and lateral radiographs of 250 normal wrist (total 250) parameters. Results The ulnar variation was 0 76 ± 1 59 mm (mean ± standard deviation), the distance between the scapholunate and the lunar bone was 3 12 ± 0 73 mm, and the inclination of radius ulna was 2 259 ± 3 6 1 °. The radial inclination (B) was 6 7 89 ± 3 6 3 °; radioulnar inclination was 78 1 ± 466 °; radial lunar angle was -45 5 ± 10 2 5 °; scaphoid was 542 9 ± 8 2 0 °; the carpal angle was 12 1 0 4 ± 8 14 °; the standard wrist rate was 0 5 4 ± 0 0 4; the standard wrist index was 100 ± 0 0 36; the modified wrist height was 1 34 ± 0 0 77 ; Improved wrist high index was 100 ± 0 0 6; standard wrist rate was 0 31 ± 0 0 38; improved wrist rate was 0 77 ± 0 10; standard radial wrist rate was 0 11 ± 0 0 2 4; The improved radial wrist rate was 0 2 7 ± 0 0 5 8; Stahl’s index was 0 5 7 ± 0 0 5 4 and so on. Of the 25 parameters, 30 pairs of parameters were correlated, of which 17 were positively correlated and 13 were negatively correlated. Conclusion This article reveals the quantitative indicators of X-ray morphology of the normal wrist, which is helpful for the study of the structural dynamics of the wrist, the design of the prosthesis and the diagnosis and treatment of the disease
