Clinical analysis of real-time ultrasound-guided drug injection for piriformis syndrome / 国际生物医学工程杂志

ABSTRACT

Objective:To investigate the clinical efficacy of precise real-time ultrasound-guided drug injection in the treatment of piriformis syndrome.Methods:80 patients with piriformis syndrome enrolled and were randomly divided into the treatment group ( n=40) and the control group ( n=40). The treatment group received real-time ultrasound-guided drug injection, while the control group received conventional drug injection. A visual analogue scale (VAS) was used to evaluate the degree of pain relief after the treatment. The thickness of the piriformis muscle was measured by ultrasound, and the change in thickness was used as an auxiliary evaluation index. Results:Under the guidance of real-time ultrasound, drug injection treatment for piriformis syndrome had an obvious pain relief effect, piriformis muscle thickness was significantly restored, and the effect of precise treatment was achieved. After 3 weeks of treatment, the clinical standard cure rate in the treatment group was 97.5%, and the cure rate in the ultrasonic diagnosis of the piriformis muscle was 95%. Both were higher than in the control group, and the difference was statistically significant (all P<0.05). Conclusions:Real-time ultrasound-guided drug injection for piriformis syndrome can achieve an accurate and significant therapeutic effect compared with traditional blind puncture. The real-time ultrasound-guided drug injection is safe, simple, radiation-free, and has a significant therapeutic effect. Therefore, this method for treating piriformis syndrome is worthy of being vigorously promoted in clinical practice.
