Background & Aims
Stenosing tenosynovitis of the finger flexor tendon (trigger finger) is a pathological change that occurs between the finger pulley and the flexor tendon. Its incidence in the general population is about 2.6%, while it is 10% in the diabetic population [1]. It commonly occurs between the ages of 50-60, with a higher prevalence in women than men [2]. The most commonly affected fingers are the ring finger, middle finger, and thumb [2]. Stenosing tenosynovitis of the finger flexor tendon can be detected by the patient’s complaint of pain and finger stiffness, with the key diagnostic indicator being finger pain during movement, accompanied by gradually developing finger flexion and extension limitations and triggering [3]. Imaging diagnosis is important for assessing the degree of trigger finger, formulating treatment plans, guiding treatment sites, and evaluating post-treatment efficacy [4]. To explore the efficacy of needle knife treatment for stenosing tenosynovitis of the thumb.
Methods
A total of 50 patients with stenosing tenosynovitis of the thumb who visited our hospital from June 2020 to June 2022 were collected and randomly divided into a control group (Group C) and an observation group (Group A) using a random number table method. The control group underwent conventional ultrasound-guided needle knife treatment, while the observation group underwent needle knife treatment based on anisotropic ultrasound guidance. The operation time, amount of bleeding, number of incisions, satisfaction level, and adverse reactions within 10 days after surgery were recorded for both groups.
Results
The operation time of Group A was significantly shorter than that of Group C (15±11 min vs 30±9 min, p<0.05). The amount of bleeding in Group A was significantly less than that in Group C (3±1.5 ml vs 8±1.8 ml, p<0.05). The number of incisions with a small needle knife in Group A was significantly less than that in Group C (35±5 times vs 60±8 times, p<0.05). The satisfaction level of both doctors and patients in Group A was significantly higher than that in Group C (p<0.05). There were no cases of neurological complications in Group A, while there was 1 case in Group C, which was significantly higher than that in Group A (p<0.05). The postoperative VAS score in Group A was significantly lower than that in Group C (0.9±0.2 vs 2.3±0.3, p<0.05).
Conclusions
Ultrasound-guided needle knife treatment based on anisotropic ultrasound guidance can improve surgical efficiency, reduce intraoperative bleeding, minimize the occurrence of postoperative neurological and vascular complications, and achieve higher satisfaction levels for both doctors and patients in the treatment of stenosing tenosynovitis of the thumb.
