Abstract：Objective To explore the effect of lateral approach joint release combined with systematic re-habilitation on traumatic metacarpophalangeal joint stiffness.Methods From July 2022 to July 2023,120 patients with post-injury metacarpophalangeal stiffness were recruited from the Rehabilitation Department of Pingyin County People's Hospital.According to different treatment plans,they were divided into the study group(lateral approach joint release+systematic rehabilitation,n=60)and the control group(conventional rehabilitation,n=60 cases).Joint range of motion,metacarpophalangeal function,mastery,grip duration,and fingertip pressure were compared between two groups.Methods From July 2022 to July 2023,120 patients with post-injury metacarpophalangeal stiffness were recruited from the Rehabilitation Department of Pingyin County People's Hospital.According to different treatment plans,they were divided into the study group(lateral approach joint release+systematic rehabili-tation,n=60 cases)and the control group(conventional rehabilitation,n=60).Joint range of motion,metacarpophalangeal function,mastery,grip duration,and fingertip pressure were compared between two groups.Results Before treatment,there were no significant differences in active joint motion,passive joint motion,and upper limb DASH score be-tween the two groups(P＞0.05).After treatment,active joint motion in both groups increased(P＜0.001),and pas-sive joint motion in both groups increased more significantly(P＜0.001),while the active and passive joint motion of the study group increased more than those of the control group increased(P＜0.001).After treatment,upper limb DASH scores decreased in both groups(P＜0.001),and the reduction was more significant in the study group than in the control group(P＜0.001).Before treatment,there were no significant differences in grip strength,grip strength duration,and fingertip pressure between the two groups(P＞0.05).After treatment,grip strength,grip strength dura-tion,and fingertip pressure of both groups significantly increased(P＜0.001),but there were no significant dif-ferences in grip strength,grip strength duration,and fin-gertip pressure increase degree between the two groups(P＞0.05).Conclusion Lateral approach joint release combined with systematic rehabilitation can significantly improve the range of motion and metacarpal and digital function of the affected palm,which is conducive to the re-covery of patients.
