Ultrasound-guided acupotomy for trigger finger: a systematic review and meta-analysis.

BACKGROUND: Trigger finger is a common condition in the hand, and ultrasound-guided acupotomy for trigger finger has been widely used in recent years. PURPOSE: This study aims to investigate the efficacy and safety of ultrasound-guided acupotomy for trigger finger. METHODS: We searched for relevant studies in the Cochrane Library, China National Knowledge Infrastructure (CNKI), Embase, PubMed, Chinese Biomedical Literature Database (CBM), Wanfang Data, and other resources from their inception to January 2023. Randomized controlled trials of ultrasound-guided acupotomy for trigger finger were included. The meta-analysis was carried out using Review Manager 5.4 and Stata 15.1. RESULTS: Overall, 15 studies with 988 patients were included. The experimental group was treated with ultrasound-guided acupotomy, and the Control group received traditional acupotomy, traditional operation or injection of medication. Meta-analysis showed that the overall clinical effectiveness (OR = 4.83; 95% CI 2.49-9.37; I2 = 73.1%; P < 0.001) in the experimental group was significantly better than that of the control group. And the Visual Analogue Scale (VAS) score (WMD = - 1; 95% CI - 1.24, - 0.76; I2 = 99%; P < 0.001), the QuinneII classification (WMD = - 0.84; 95% CI - 1.28, - 0.39; I2 = 99.1%, P < 0.001), the incidence of complications (RR = 0.26; 95% CI 0.11, 0.63; I2 = 0%, P = 0.003), and the recurrence rate (RR = 0.14; 95% CI 0.03, 0.74; I2 = 0%; P = 0.021) were significantly lower in the experimental group. CONCLUSION: Our systematic review and meta-analysis can prove the effectiveness and safety of ultrasound-guided acupotomy in the treatment of trigger finger, but this still needs to be verified by a clinical standard large sample test.

Current Concepts in the Management of Trigger Finger in Adults.

Trigger finger (TF) is one of the most common causes of hand disability. Immobilization of TF with a joint-blocking orthosis has been demonstrated to effectively relieve pain and improve function. The efficacy of steroid injections for TF varies based on the number of affected digits and the clinical severity of the condition. Up to three repeat steroid injections are effective in most patients. When conservative interventions are unsuccessful, open surgical release of the A1 pulley effectively alleviates the subjective and objective manifestations of TF and currently remains the benchmark procedure for addressing TF. Although several studies have emerged suggesting that a percutaneous approach may result in improved outcomes, this technique demands a learning curve that may predispose patients to higher risk of procedure-related complications. There is no role for preoperative antibiotics in patients who undergo elective soft-tissue procedures of the hand. WALANT anesthesia has gained popularity because it has been associated with improved patient outcomes and a clear cost savings; however, proper patient selection is critical. Similar to other soft-tissue hand procedures, TF surgery rarely necessitates a postoperative opioid prescription.

Clinical indications for image-guided interventional procedures in the musculoskeletal system: a Delphi-based consensus paper from the European Society of Musculoskeletal Radiology (ESSR)-Part II, elbow and wrist.

BACKGROUND: Although image-guided interventional procedures of the elbow and wrist are routinely performed, there is poor evidence in the literature concerning such treatments. Our aim was to perform a Delphi-based consensus on published evidence on image-guided interventional procedures around the elbow and wrist and provide clinical indications on this topic. METHODS: A board of 45 experts in image-guided interventional musculoskeletal procedures from the European Society of Musculoskeletal Radiology were involved in this Delphi-based consensus study. All panelists reviewed and scored published papers on image-guided interventional procedures around the elbow and wrist updated to September 2018 according to the Oxford Centre for Evidence-based Medicine levels of evidence. Consensus on statements drafted by the panelists about clinical indications was considered as "strong" when more than 95% of panelists agreed and as "broad" if more than 80% agreed. RESULTS: Eighteen statements were drafted, 12 about tendon procedures and 6 about intra-articular procedures. Only statement #15 reached the highest level of evidence (ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement). Seventeen statements received strong consensus (94%), while one received broad consensus (6%). CONCLUSIONS: There is still poor evidence in published papers on image-guided interventional procedures around the elbow and wrist. A strong consensus has been achieved in 17/18 (94%) statements provided by the panel on clinical indications. Large prospective randomized trials are needed to better define the role of these procedures in clinical practice. KEY POINTS: • The panel provided 18 evidence-based statements on clinical indications of image-guided interventional procedures around the elbow and wrist. • Only statement #15 reached the highest level of evidence: ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement. • Seventeen statements received strong consensus (94%), while broad consensus was obtained by 1 statement (6%).

Acupotomy for patients with trigger finger: A systematic review protocol.

BACKGROUND: Trigger finger is thought to be caused by aseptic inflammation of the A1 pulley and subsequent thickening and narrowing of the fibrous sheath. Acupotomy has been an important treatment for trigger finger. But an updated systematic review about this issue has not yet been released. This systematic review protocol is aimed at providing a higher quality method used to evaluate the efficacy and safety of acupotomy treatment for trigger finger. METHODS: The following databases will be searched from the study inception to July 2019: the Cochrane Central Register of Controlled Trials (Cochrane Library), MEDLINE, EMBASE, PubMed, China National Knowledge Infrastructure, Wan-Fang Data, and Chinese Biomedical Literature Database. All English or Chinese randomized controlled trials related to acupotomy for trigger finger will be included. Two reviewers will independently perform the processes of study inclusion, data extraction, and quality assessment. The primary outcome will be assessed by improvement of the pain symptoms and finger activity. Secondary outcomes will be assessed through Safety assessment. Meta-analysis will be completed by RevMan V.5.3 software. RESULTS: This systematic review will provide an assessment of the current state of acupotomy for trigger finger, aiming to show the efficacy and safety of treatment. CONCLUSION: This systematic review will re-evaluate a higher-quality systematic review to obtain a relatively convincing conclusion that finds acupotomy to be a better choice for trigger finger patients.

[Ultrasound-guided needle-knife for trigger finger].

OBJECTIVE: To explore the efficacy of ultrasound-guided needle-knife with precise three-dimensional stereotactic localization of ashi points for stenosing tenosynovitis of flexor tendon (trigger finger). METHODS: A total of 74 patients were randomly divided into an observation group and a control group, 37 cases in each group. The patients in the observation group were treated with ultrasound-guided intrathecal injection and releasing method of needle-knife, while the patients in the control group were treated with ultrasound-guided intrathecal injection. The self-made 9-score scale of trigger finger was recorded before treatment, immediately after treatment, 1 month and 3 months after treatment; the curative effect of the two groups was evaluated. RESULTS: The results of self-made 9-score scale in the observation group immediately after treatment, 1 month and 3 months after treatment were lower than that before treatment (all P<0.01); the scores in the observation group were lower than those in the control group at each time point after treatment (all P<0.01). The excellent and good rate immediately after treatment was 100.0% (37/37) in the observation group, which was superior to 8.1% (3/37) in the control group (P<0.05); the cured rates in the observation group were 100.0% (37/37) 1 month after treatment and 97.3% (36/37) 3 months after treatment, which were superior to 13.5% (5/37) and 10.8% (4/37) in the control group, respectively (P<0.05). CONCLUSION: The needle-knife with three-dimensional stereotaxic location of ashi point could significantly improve the symptoms of trigger finger, with superior immediate and long-term efficacy.

Acupuncture for the treatment of trigger finger in adults: a prospective case series.

OBJECTIVE: To determine the effect of acupuncture performed at the synovial and ligamentous tendon sheath (A1 pulley site) on pain during snapping and the severity of the snapping phenomenon in patients with trigger finger. METHODS: In this observational study, changes in the patients' condition were compared before and after acupuncture treatment. Acupuncture was performed on 19 fingers of 15 patients. Acupuncture needles were inserted into the radial and ulnar sides of the flexor tendon at the A1 pulley of the affected finger. Treatment was performed daily up to a maximum of five times. Before and after each treatment, pain during snapping and the severity of snapping were evaluated using a visual analogue scale (VAS). RESULTS: VAS scores for pain and snapping severity were significantly improved immediately after the first treatment (p<0.001). Pain during snapping, assessed before each treatment, improved over time, reaching statistical significance from the second treatment onwards (p<0.001); similarly, a significant improvement in the severity of snapping was observed, also from the second treatment (p<0.001). Patients with clinically significant improvements (≥50%) in pain and snapping severity had a significantly shorter duration of the disorder than those with <50% improvement (p<0.05). CONCLUSIONS: Acupuncture at the impaired A1 pulley site may be an effective treatment for trigger finger. We postulate that acupuncture may reduce inflammation/swelling of the synovial membrane of the tendon sheath, which predominates when the disorder is of short duration. Further research is required to confirm the efficacy/effectiveness of acupuncture for trigger finger and its mechanisms of action.
