Abstract：Objective To investigate the pressure distribution of wrist small splint at 90° elbow flexion,and to provide a method and references for the quantitative study of small splints.Methods The pressure measurement membrane chemical color rendering method was used,and the Python algorithm was used to digitally display the pressure difference in the form of thermal map.The color was used to visualize the pressure distribution data,taking the small splint for Colles'fracture at the metacarpal flexion-ulnar deviation and 90° flexural elbow position as an example.Results Grayscale equalization front pressure:palmar plate(1.58±0.285)N/cm2,dorsal plate(1.34±0.178)N/cm2,ulnar plate(1.55±0.250)N/cm2,radial plate(1.48±0.242)N/cm2.Pressure after grayscale equalization:palmar plate(1.59±0.270)N/cm2,dorsal plate(1.33±0.196)N/cm2,ulnar side plate(1.55±0.255)N/cm2,radial plate(1.47±0.238)N/cm2;There was no significant difference in the pressure values before and after grayscale equalization of palmar plate,dorsal plate,ulnar plate,and radial plate.Conclusions It is feasible to use the visualization algorithm for reading,and the pressure obtained by the visualization algorithm is more accurate with analysis and research value.The average pressure of the palmar plate is the largest,followed by the ulnar plate and the radial plate when the elbow is bent at 90°.The average pressure of the dorsal plate is the smallest.
