The effect of COMP gene mutation on the clinical efficacy and prognosis of the treatment of carpal tunnel syndrome with ultrasound-guided crochet knife.

Objective To analyze the effect and prognosis of COMP gene mutation on the treatment of carpal tunnel syndrome with ultrasound-guided dental crochet knife. Methods A total of 35 carpal tunnel syndrome patients with Cartilage oligomeric matrix protein gene mutation (COMP) who were treated in the outpatient department from June 2022 to June 2023 were selected as the control group. Another 40 patients with carpal tunnel syndrome without mutation of COMP gene who received treatment during the same period were selected as the observation group. All patients were treated with ultrasound-guided lower tooth crochet knife. The Transverse carpal ligament thickness, paresthesia score, muscle loss score and transverse carpal ligament thickness were compared between the two groups. Pisiform cross section median nerve cross section area, pisiform cross section median nerve cross section area, CSA), Anterior and posterior diameter of median nerve in cross section of uncinate bone (D), clinical efficacy and incidence of adverse events. Results After treatment, compared with observation group, paresthesia score, hand function satisfaction score, TTCL, CSA and D in control group were all increased, while muscle loss score was decreased, with statistical difference (P < 0.05). In addition, the total clinical efficiency increased significantly and the incidence of adverse effects decreased significantly in the observation group. The prognosis of carpal tunnel syndrome patients with COMP gene mutation was evaluated according to the satisfaction degree of hand function, which showed that compared with the good prognosis group, the hand function score of the poor prognosis group increased significantly, with statistical difference (P < 0.05). Before treatment, there was no significant difference in clinical manifestations between the two groups (P > 0.05). Conclusions The application of ultrasound-guided crochet in carpal tunnel syndrome patients with COMP gene mutation plays an important role in the development of carpal tunnel syndrome.
