Ultrasound-guided syringe needle laceration in the treatment of stenosing tenosynovitis / 中国微创外科杂志

ABSTRACT

Objective To investigate the clinical effects of tendon sheath laceration by syringe needle under the guidance of ultrasonography in the treatment of stenosing tenosynovitis. Methods A retrospective comparison was made on the curative efficacy in 78 patients with stenosing tenosynovitis of the hand. The patients were divided into two groups the treatment group (n=39) was given tendon sheath laceration by 20-gauge syringe needle under the guidance of 10 MHz ultrasonography, while the control group ( n= 39) received the conventional puncture and laceration without the ultrasound guidance. Results At the fourth postoperative week, complete pain relief was achieved in 32 patients in the treatment group (82.1%) and in 20 patients in the control group (51.3%), respectively, with a significant difference ( ? 2 =8.34, P =0.004). The visual analogue score (VAS) was 8.9~3.5 (mean, 6.7?2.0) lower than before operation in the treatment group and 8.5~0.5 (mean, 5.2?2.9) in the control group. The pain relief in the treatment group is significantly superior to that in the control group ( t =2.659, P =0.010). Conclusions Ultrasound-guided laceration of the stenotic tendon sheath by syringe needle is a simple, minimally invasive and effective option for the management of stenosing tenosynovitis of the hand.
