Clinical Effect of Ultrasound-Guided Needle-Knife Release in the Treatment of Flexor Tendon Stricture Tenosynovitis of Thumb

Abstract

Abstract: Objective To investigate the clinical effect of ultrasound-guided needle-knife release therapy on patients with constricted tenosynovitis of flexor tendon of thumb. Methods A total of 60 patients with constricted tenosynovitis of flexor tendon of thumb admitted to Pingliang Hospital of Traditional Chinese Medicine from January 2023 to January 2024 were randomly divided into control group and study group,each consisting of 30 cases. The control group was given blind needle-knife release treatment, and the study group was given ultrasound-guided needle-knife release treatment.The clinical efficacy, pain degree, finger function, total active range of motion (TAM),A1 trochlear parameters and complications were compared between the two groups. Results The total effective rate of treatment in the study group was higher than that in the control group, with a statistically significant difference (P<0.05). After treatment, both groups showed a decrease in the Numerical Rating Scale (NRS) for pain intensity, and the NRS score in the study group was lower than that in the control group, with a statistically significant difference (P<0.05). The finger function and TAM of the study group were better than those of the control group, with a statistically significant difference (P<0.05). After treatment, both groups experienced a reduction in A1 trochlear length and thickness, and the study group had lower values for all indicators compared to the control group, with a statistically significant difference (P<0.05). The incidence of complications in the study group was lower than that in the control group, with a statistically significant difference (P<0.05). Conclusion Ultrasound-guided needle-knife release therapy can improve clinical efficacy, reduce pain, improve finger function, TAM, adjust A1 trochlear parameters, and has high safety in patients with flexor tendon stenosis tenosynovitis of thumb.

Key words: constrictive tenosynovitis of flexor tendon of thumb, ultrasonic guidance, acupotomy release, degree of pain, finger function
