Sociodemographic diversities of the anatomical anthropometries in the wrist of Egyptians -A cross-sectional study in 2021-2022

Background: To restore the structural and functional architecture of the wrist joint, radiographic evaluation is essential. Diversities based on age, race, and gender were noted. The objective of this study was to assess a few wrist radiography characteristics and establish correlations between them and the sociodemographic traits.Methods: During the years 2021–2022, 238 posteroanterior plain x-ray wrist pictures were gathered and evaluated from the radiology departments of Zagazig University hospitals in Egypt. The following parameters were estimated: ulnar variance, radial height, radial inclination, scaphoid length, lunate length, scapholunate distance, capitate length, carpal height, third metacarpal length, revised carpal height ratio, and scaphoid-capitate ratio. The t-test, ANOVA, Kendall's tau_b correlation, and linear regression were used to conduct the comparisons.Results: Radial height, inclination, and ulnar variation all showed significant gender differences (p=0.004, 0.013, and 0.002, respectively). The carpal height and carpal height ratio, together with the radial cord, scaphoid, lunate, capitate, and third metacarpal lengths, all demonstrated significant results (p < 0.001). The right side had a greater radial cord, height, and radial inclination than the left; nevertheless, the left side had a substantially longer lunate (P=0.0168, <0.001, 0.049, and <0.001, respectively). Age differences revealed varying levels of significance in the following areas: carpal height, carpal height ratio, ulnar variance, scapholunate space, capitate height, scapho-capitate ratio, and radial cord (p=0.044, 0.011, 0.039, 0.026, 0.048, 0.002 and 0.017, respectively).Conclusion: When treating wrist problems, variations in wrist characteristics should be given careful consideration. To suggest algorithms that could improve the results of wrist diseases in Egyptians, more research is required.
