The pathogenesis of the carpal tunnel syndrome is related to the excessive flexion and extension of the wrist joint and the strain, such as due to the improper posture of grasping the snowstick when skiing. This paper evaluates the effect and the safety of ultrasound-assisted endoscopic carpal tunnel release. 51 patients with unilateral carpal tunnel syndrome admitted to our hospital from June 2019 to December 2020 are selected to be treated with the endoscopic transverse carpal ligament release assisted by ultrasound. In addition, the Boston Carpal Tunnel Scale Symptom Severity Scale (SSS), the Boston Carpal Tunnel Scale Functional Status Scale (FSS), the median nerve flattening rate at the level of the hamate bone (FR) are recorded before the surgery, and 1 month and 3 months after the surgery. According to the follow-up among the 51 patients, the SSS score and the FSS score of patients 1 month and 3 months after the surgery are significantly lower than those before the surgery, with statistical significance (P<0.05) and the FR is decreased gradually 1 month and 3 months after the surgery, with statistical significance (P<0.05). According to the current status and the suggestions in the functional evaluation standard for the carpal tunnel syndrome and the cubital tunnel syndrome, the good rate is 98.0%, because of no vascular nerve injury, infection and other complications. Endoscopic transverse carpal ligament release assisted by ultrasound can visualize the transverse carpal ligament and its surrounding anatomical structure through a small incision to evaluate the release effect of the transverse carpal ligament and to reduce the complications of the vascular and nerve injury. Besides, the postoperative patients have recovered well and are satisfied with the treatment effect, so the treatment is worthy of clinical promotion.
