Abstract: This study investigated the effect of lidocaine + trisineacetonide + VitB12 suspension injection combined with fine-needle aspiration under ultrasound and modified small needle knife in the treatment of patients with carpal tunnel syndrome. 60 patients with carpal tunnel syndrome were selected as the research objects, and divided them into the study group and the control group with 30 cases in each group by random number table method. The patients in the study group were treated with lidocaine + trisineacetonide + VitB12 suspension injection combined with fine-needle aspiration under ultrasound and modified small needle knife, and the control group was treated with lidocaine + trisineacetonide + VitB12 suspension injection combined with traditional small needle knife. The visual analog pain scale (VAS) scores after 1 course, 2 courses and 3 courses of treatment were lower than those in the control group (P<0.05). After treatment, the symptom severity scale score and functional status scale score of the patients in the study group were lower than those in the control group, and the difference was statistically significant (P<0.05). The median nerve sensory conduction velocity in the study group was faster than that in the control group (P<0.05), the motor terminal latency of the study group was shorter than that of the control group (P<0.05). After 3 courses of treatment, the overall therapeutic effect of the study group was better than that of the control group (P<0.05). Lidocaine + trisineacetonide + VitB12 suspension injection combined with fine needle aspiration under ultrasound and modified small needle knife in the treatment of carpal tunnel syndrome can effectively improve the clinical symptoms of patients and improve the clinical treatment effect.
