Percutaneous release of the trigger thumb: is it safe, cheap and effective?
(1/32)
Percutaneous release of the trigger finger and trigger thumb has recently gained popularity. The aim of this study was to determine the clinical results and safety of percutaneous release in trigger thumbs. Twenty-five thumbs of 21 patients were released percutaneously in the polyclinic under local anaesthesia. Steroid injection was performed following the release procedure using the same needle. The thumb function was evaluated by a patient questionnaire, and functional thumb scores (VAS) were calculated in the preoperative and postoperative periods. At the 1 week follow-up, four patients had signs of discomfort and triggering because of incomplete release. These patients underwent open A1 pulley release. Three superficial tendon lacerations were seen during these open procedures. There were no wound complications or signs of digital nerve or artery injury in any of the patients. The preoperative mean VAS was 26.62 (18-36). This decreased to 2.57 (0-5) at the first postoperative month (P<0.001) and to 2.19 (0-3; P<0.001) at the sixth month. When the VAS scores at the first and sixth months were compared, the difference was statistically significant. We concluded that percutaneous release of trigger thumbs is a cheap, safe and effective procedure with a low rate of complications. (+info)
Trigger finger as an initial manifestation of familial amyloid polyneuropathy in a patient with Ile107Val TTR.
(2/32)
We describe a Japanese family with transthyretin Val107-related familial amyloid polyneuropathy (FAP). The clinical features were high-aged onset, sensorimotor polyneuropathy, carpal tunnel syndrome (CTS) and trigger finger. In addition, the proband showed cardiac conduction block and amyloid deposition in the sural nerve and dermis. Trigger finger may be a so far unknown clinical manifestation of Val107 FAP due to amyloid deposition in the connective tissue like CTS. (+info)
Sonographic appearance of trigger fingers.
(3/32)
OBJECTIVE: The purpose of this study was to describe the sonographic appearance of the first annular (A1) pulley-flexor tendon complex in patients with trigger fingers. METHODS: Thirty-three trigger fingers in 33 patients were examined with a 7- to 15-MHz probe. A control group consisted of 20 patients without trigger fingers. The study included systematic measurement of the thickness of the A1 pulley and a power Doppler assessment of the pulleys, tendons, and tendon sheaths. RESULTS: Thickening and hypoechogenicity of the A1 pulley were found in all patients with trigger fingers. Measurements of A1 pulley thickness were significantly different (P < .0001) between the groups without trigger fingers (mean, 0.5 mm; range, 0.4-0.6 mm) and with trigger fingers (mean, 1.8 mm; range, 1.1-2.9 mm). Hypervascularization of the A1 pulley on power Doppler imaging was found in 91% of the trigger fingers but was never found in the healthy control group. Flexor tendinosis was found in 48% of the trigger fingers; tenosynovitis was found in 55%; and both were found in 39%. In the control group, tenosynovitis and tendinosis were not found. CONCLUSIONS: Thickening and hyper-vascularization of the A1 pulley are the hallmarks of trigger fingers on sonography. Other frequently observed features include distal flexor tendinosis and tenosynovitis. (+info)

Ultrasound-guided first annular pulley injection for trigger finger.
(7/32)
OBJECTIVE: The purpose of this study was to develop an ultrasound-guided first annular (A1) pulley injection technique for trigger finger with documentation of outcomes at 1 year. METHODS: We performed a short-axis injection into a triangle bordered by the A1 pulley, the flexor digitorum superficialis and profundus tendons and volar plate, and the distal metacarpal bone with a 10-mg median dose of triamcinolone acetonide and 2% lidocaine. This was a prospective study of 50 of 52 consecutive trigger fingers from 24 patients recruited from a physical medicine and rehabilitation private practice. RESULTS: All patients were available for follow-up, with 94% (47 of 50) of fingers having complete resolution of symptoms at 6 months, 90% (37 of 41) at 1 year, 65% (17 of 26) at 18 months, and 71% (12 of 17) at 3 years after a single injection. CONCLUSIONS: Our ultrasound-guided A1 pulley injection technique is a highly effective and minimally invasive treatment option for trigger finger with a 90% success rate at 1 year for complete resolution of symptoms after a single injection. Assuming similar patient populations, our results were statistically significant (P < .01) compared with the 56% to 57% success rates recently reported for blind injections. (+info)
Corticosteroid injections for trigger finger.
(8/32)
BACKGROUND: Trigger finger is a disease of the tendons of the hand leading to triggering (locking) of affected fingers, dysfunction, and pain. Available treatments include local injection with corticosteroids, surgery, or splinting. OBJECTIVES: To summarize the evidence on the effectiveness and safety of corticosteroid injections for trigger finger in adults using the following endpoints: treatment success, frequency of triggering or locking, functional status of the affected fingers, and severity of pain of the fingers. SEARCH STRATEGY: The databases CENTRAL, DARE, Medline (1966 to November 2007), EMBASE (1956 to November 2007), CINAHL (1982 to November 2007), AMED (1985 to November 2007), and PEDro (a physiotherapy evidence database) were searched. SELECTION CRITERIA: The authors selected randomized and controlled clinical trials evaluating effectiveness and safety of corticosteroid injections for trigger finger in adults. DATA COLLECTION AND ANALYSIS: The databases were searched for titles of eligible studies. After screening abstracts of these studies, full text articles of studies that fulfilled the selection criteria were obtained. Data were extracted using a predefined electronic form. The methodologic quality of included trials was assessed by using items from the checklist developed by Jadad and the Delphi list. The authors planned to extract data regarding information on the primary outcome measures: treatment success, frequency of triggering or locking, functional impairment of fingers, and severity of the trigger finger; and the secondary outcome measures: proportion of patients with side effects, types of side effects, and patient satisfaction with injection. MAIN RESULTS: Two randomized controlled studies were found that involved 63 participants: 34 were allocated to corticosteroids and lidocaine (Xylocaine), and 29 were allocated to lidocaine alone. Corticosteroid injection with lidocaine was more effective than lidocaine alone on treatment success at four weeks (relative risk = 3.15; 95% confidence interval, 1.34 to 7.40). The number needed to treat to benefit was 3. No adverse events or side effects were reported. AUTHORS' CONCLUSIONS: The effectiveness of local corticosteroid injections was studied in only two small randomized controlled trials of poor methodologic quality. Both studies showed better short-term effects of corticosteroid injection combined with lidocaine compared with lidocaine alone on the treatment success outcome. In one study, the effects of corticosteroid injections lasted up to four months. No adverse effects were observed. The available evidence for the effectiveness of intratendon sheath corticosteroid injection for trigger finger can be graded as a silver level evidence for superiority of corticosteroid injections combined with lidocaine over injections with lidocaine alone.
