Abstract：Objective To investigate the safety and accuracy of ultrasound guided needle knife release in extremity disease. Methods Twenty human specimens fixed with formalin were selected from the Department of Human Anatomy, School of Basic Medical Sciences, Peking University, the study was conducted from March 2019 to June 2022. Specimens were divided into traditional operation group and ultrasonic guided group, with ten specimens in each group, and the needle knife release operation was carried out under the same approach. The traditional operation group performed the needle knife release operation under invisible conditions, while the ultrasonic guided group performed the operation under the guidance of the high frequency probe. After the operation of needle loosening, the needle was kept, dissected layer by layer, and the needle path was observed, the success rate, accuracy and injury rate of conventional operation and ultrasound guided operation were compared in four diseases of radial stylostenosis tenosynovitis, flexor constriction tenosynovitis, carpal tunnel syndrome, and malleolar tunnel syndrome. Results The success rate of operation on carpal tunnel syndrome in ultrasound guided group was higher than that in traditional operation group, and the difference was statistically significant (P＜0.05). The operation release efficiency of flexor stenosis tenosynovitis, carpal tunnel syndrome, and ankle tunnel syndrome in ultrasound guided group was higher than that in traditional operation group, and the differences were statistically significant (P＜0.05). The operation injury rate of ultrasound guided group was lower than that of traditional operation group, and the difference was statistically significant (P＜0.05). Conclusion Ultrasound guided needle knife release technique has high safety and accuracy in the operation of terminal extremity diseases, which is worthy of clinical promotion.
