Abstract: Objective   To explore the effects of small incision in situ release on surgical indications,nerve conduction velocity and upper limb function in patients with carpal tunnel syndrome(CTS). Methods   A total of 100 CTS patients admitted to our hospital from January 2018 to January 2022 were selected,they were randomly divided into the control group(50 cases,treated with traditional carpal tunnel release) and the observation group(50 cases,treated with small incision in situ release),the clinical data of CTS patients were collected and surgical indications,nerve conduction velocity,upper limb function and the incidence of complications were compared between the two groups. Results   The total effective rate was 98.00% in the observation group and 84.00% in the control group(P<0.05).In the observation group,the length of incision was(1.65±0.29) cm,the time of opening and closing incision was(4.85±1.02) min,the hospitalization time was(3.24±0.62) d,the intraoperative blood loss was(17.88±3.53) mL,and the VAS score was(3.03±0.56) points one day after operation.The control group were(4.02±0.81) cm,(10.06±2.28) min,(7.11±1.34) d,(24.37±5.27) ml,(4.04±0.89) points,the differences were statistically significant(P<0.05).After treatment,The thumle-wrist sensory conduction velocity of CTS patients in the study group was(46.05±8.39) m/s,the middle finger-wrist sensory conduction velocity was(45.05±8.95) m/s,the thenar muscles-wrist motor conduction velocity was(53.94±11.47) m/s,the FIM ADL score was(34.38±7.22) points,and FMA The upper limb score was(34.23±7.25) points,and the control group was(41.86±8.22) m/s,(40.88±8.28) m/s,(49.05±10.01) m/s,(27.81±6.01) points,(41.05±9.19) points.The difference between the two groups was statistically significant(P<0.05).The total incidence of complications was 4.00% in the observation group and 20.00% in the control group(P<0.05). Conclusion   Small incision in situ release is effective in the treatment of CTS patients,which can improve the surgical indications and nerve conduction velocity,help patients recover upper limb function,and reduce the incidence of postoperative complications.
