Introduction: Histological examination of tissue specimens obtained during surgical treatment of trigger finger frequently encountered unclassifiable amyloid deposits in the annular ligament. We systematically explored this unknown type by a comprehensive analysis using histology, immunohistochemistry, and quantitative mass spectrometry-based proteomics. Methods: 205 tissue specimens of annular ligaments were obtained from 172 patients. Each specimen was studied by histology and immunohistochemistry. Tissue specimens obtained from ten patients with histology proven amyloid in annular ligament were analysed by label-free quantitative proteomics. Histological and immunohistochemical findings were correlated with patient demographics. Results: Amyloid was present as band like deposits along the surface of annular ligament, dot like or patchy deposits within the matrix. Immunohistochemistry identified ATTR amyloid in 92 specimens (mostly patchy in the matrix), while the band like deposits of 100 specimens remained unclassifiable. Proteomic profiles identified the unknown amyloid as most likely of fibrinogen origin. The complete cohort was re-examined by immunohistochemistry using a custom-made antibody and confirmed the presence of fibrinogen alpha-chain (FGA) in a hitherto unclassifiable type of amyloid in annular ligament. Conclusion: Our study shows that two different types of amyloid affect the annular ligament, ATTR amyloid and AFib amyloid, with distinct demographic patient characteristics and histomorphological deposition patterns.

Background: It is not clear whether rehabilitation after surgery for trigger finger is effective. The aim of this study was to reveal its effectiveness for trigger finger. Methods: This study was a randomized, controlled trial that included patients who underwent operations for trigger fingers. The patients in the rehabilitation group had postoperative occupational therapy (OT) for 3 months, while the patients in the control group were not referred for rehabilitation but received advice for a range of motion exercises. We evaluated the severity of trigger finger, Disability of Arm-Shoulder-Hand (DASH) score, pain-visual analogue scale (VAS), grip strength, whether they gained a full range of motion (ROM), and complications before and after surgery. Results: Finally, 29 and 28 patients were included in the control and rehabilitation groups, respectively. At final follow-up, the DASH score, grip strength, and ROM were significantly improved in the rehabilitation group compared to that preoperatively. At final follow-up, pain was significantly improved in both groups from that preoperatively. There were no significant differences in the results, including the DASH score, grip strength, ROM and pain-VAS between the control and rehabilitation groups at the final follow-up. Subgroup analysis showed that there is a significant difference in the DASH score of patients doing housework or light work and those with a duration of symptoms >12 months between the control and rehabilitation groups at the final follow-up.

Background: With percutaneous and minimally-invasive pulley release becoming more popular, safety and reliability of such minimally-invasive procedures remain a concern. Visualization of the technical steps by ultrasound suggests increased safety but shows the potential for harm to tendons, nerves and vessels without proper instrumentation. We present the results of implementing a sonographically guided minimally-invasive procedure in 106 trigger digits of 64 patients between 2018–2021. Methods: A guide instrument for use with a commercially available hook knife was developed and tested in 16 cadaver hands. Due to complication early in our clinical series this guide was modified in due course. A revised design of the guide has been in use since November 2019 with improved performance and safety. Results: One hundred six procedures in 64 patients were performed. After guide revision, we report a success rate of 97.3%. Complications after instrument revision include two cases of incomplete pulley release and one case of inadvertent skin laceration. The majority of patients report returning to all strenuous activities within two weeks at most apart from four individuals with prolonged postoperative discomfort. Conclusion: We present the results of the development and implementation of a novel guide instrument for use with a hook knife to treat trigger finger. Despite several limitations of this study, we show that sonographically controlled, minimally-invasive A1 pulley release can be performed safely and effectively with appropriate surgical instruments and practice.

Background: Cost and compliance are 2 factors that can significantly affect the outcomes of non-operative and operative treatment of trigger finger (TF) and both may be influenced by social factors. The purpose of this study was to investigate socioeconomic disparities in the surgical treatment for TF. Methods: Adult patients (≥18 years old) were identified using International Classification of Diseases 9 and 10 Clinical Modification diagnostic codes for TF and Current Procedural Terminology (CPT) procedural codes (CPT: 26055) in the New York Statewide Planning and Research Cooperative System database. Each diagnosis was linked to procedure data to determine which patients went on to have TF release. A multivariable logistic regression was performed to assess the likelihood of receiving surgery. The variables included in the analysis were age, sex, race, social deprivation index (SDI), Charlson Comorbidity Index, and primary insurance type. A P -value <.05 was considered significant. Results: Of the 31 411 TF patients analyzed, 8941 (28.5%) underwent surgery. Logistic regression analysis showed higher odds of receiving surgery in females (odds ratio [OR]: 1.108) and those with workers compensation (OR: 1.7). Hispanic (OR: 0.541), Asian (OR: 0.419), African American (OR: 0.455), and Other race (OR: 0.45) had decreased odds of surgery. Medicaid (OR: 0.773), Medicare (OR: 0.841), and self-pay (OR: 0.515) reimbursement methods had reduced odds of receiving surgery. Higher social deprivation was associated with decreased odds of surgery (OR: 0.988). Conclusions: There are disparities in demographic characteristics among those who receive TF release for trigger finger related to race, primary insurance, and social deprivation.

Objectives: To 1) determine the types and frequency of complications within 3 months following ultrasound‐guided surgical procedures, and 2) identify any patient demographics, co‐morbidities, or procedural characteristics that were associated with an increased risk of complications. Methods: A retrospective chart review was performed at six Sports Medicine clinics across the United States. The Clavien‐Dindo classification was used to categorize procedural complications on a 5‐point scale from 1, representing any deviation in post‐procedure care without requiring pharmacological or invasive treatment to 5, representing death. Generalized Estimating Equations for binomial outcomes with a logit link were used to estimate the overall and procedure‐specific 3‐month complication rates. Results: Among 1902 patients, 8.1% (n = 154) had diabetes and 6.3% (n = 119) were current smokers. The analysis included 2,369 procedures, which were performed in either the upper extremity (44.1%, n = 1045) or lower extremity (55.2%, n = 1308) regions. The most common procedure was ultrasound‐guided tenotomy (69.9%, n = 1655). Additional procedures included, trigger finger release (13.1%, n = 310), tendon scraping (8.0%, n = 189), carpal tunnel release (5.4%, n = 128), soft tissue release (2.1%, n = 50), and compartment fasciotomy (1.6%, n = 37). Overall, there was a complication rate of 1.2% (n = 29 complications; 95% CI: 0.8–1.7%). Individual procedures had complication rates that ranged from 0 to 2.7%. There were 13 Grade I complications in 13 patients, 12 Grade II complications in 10 patients, 4 Grade III complications in 4 patients, and 0 Grade IV or V complications. No associations between complication risk and any patient demographics (age, sex, BMI), co‐morbidities (diabetes, smoker), or procedure characteristics (type, region) were identified. Conclusion: This retrospective review provides an evidence‐based estimate supporting the low level of risk associated with ultrasound‐guided surgical procedures for patients from a variety of geographical settings who are seeking care at private and academic‐affiliated clinics.

The purpose of this review was to summarize the current literature pertaining to ultrasound‐guided percutaneous A1 pulley release procedures. We searched PubMed, Cochrane Library, Embase, and Web of Science for clinical studies examining ultrasound‐guided percutaneous A1 pulley release. A total of 17 studies involving 749 procedures were included in this review. The overall success rate was 97%. There were 23 minor complications (4 cases of hematomas, 15 cases of persistent pain, and 4 cases of transient numbness) and no major complications reported. Ultrasound‐guided A1 pulley release is an effective and safe procedure for the treatment of trigger fingers and thumb. [ABSTRACT FROM AUTHOR]

Background: Open trigger finger release (OTFR) and endoscopic trigger finger release (ETFR) are effective methods in treating stenosing tenosynovitis. However, a paucity of literature exists comparing the techniques. This study describes and compares postoperative complications following OTFR and ETFR at a single institution. Methods: Patients undergoing trigger finger release between 2018 and 2020 within a single institution were identified. Electronic medical records were reviewed for patient demographics, surgical history, surgical characteristics, and clinical outcomes. Major and minor postoperative complications were assessed. Secondary outcome measures included tourniquet time and procedure time. Statistical analysis evaluated associations between postoperative complications, surgical technique, patient demographics, and surgical characteristics. Results: In total, 57 patients (80 digits) were included in the study: 42 digits treated with OTFR and 38 digits treated with ETFR. Mean follow-up time was 57.6 ± 69.0 days (range, 7-307 days) for ETFR and 34.2 ± 26.3 days (range, 6-120 days) for OTFR. Overall, major, and minor complication rates for the cohort were 8.8%, 1.8% and 7.0%, respectively. There were no major complications following ETFR and 1 following OTFR (4%), the isolated case being postoperative Chronic regional pain syndrome. Minor complication rates were similar following OTFR (8%) and ETFR (6%). Persistent digit stiffness and swelling were found to be the most prevalent minor complications (n = 2, respectively), followed by wound dehiscence (n = 1). Female patients were significantly more likely to experience postoperative complications. Conclusions: Major complications following trigger finger release are unlikely; however, minor complications are prominent. Patients treated with OTFR and ETFR showed similar postoperative complication rates. Continued investigations into the benefits of ETFR are warranted. [ABSTRACT FROM AUTHOR]

Background: This article compares the rates and time-to-development of new-onset Dupuytren disease in patients with trigger finger treated by steroid injection, surgical release, or both. Methods: PearlDiver's Mariner 30 database was queried to identify patients with trigger finger between January 2010 and June 2019. One-to-one exact matching based on baseline patient demographics allowed us to create 4 identical groups defined by the type of trigger finger intervention received. Results: The matched population analyzed in this study consisted of 85 944 patients who were equally represented in the steroid injection cohort (n = 21 486, 25.00%), surgical release cohort (n = 21 486, 25.00%), steroids prior to surgery cohort (n = 21 486, 25.00%), and no intervention (control) cohort (n = 21 486, 25.00%). A new Dupuytren diagnosis after trigger finger treatment occurred in 1 in 128 patients overall, 1 in 156 patients treated with steroid injection, and 1 in 126 patients treated with surgical release. Trigger fingers treated by steroid injection only had the lowest rates of Dupuytren disease overall (n = 137, 0.64%, P =.0424) and treatment with fasciectomy (n = 14, 0.07%, P <.0005). In all, 171 patients in the surgery cohort developed Dupuytren disease 1 year after undergoing surgical trigger finger release. Furthermore, this cohort had the highest rates of fasciectomy (n = 55, 0.26%, P <.0005) and the lowest rates of no intervention (n = 103, 0.48%, P =.0471). Trigger fingers managed by surgical release developed Dupuytren disease (mean, 56.11 days; SD, 80.93 days, log-rank P =.02) and underwent fasciectomy (mean, 49.74 days; SD, 62.27 days; log-rank P <.0005) more quickly than all other cohorts. Conclusions: Patients solely undergoing surgical release of their trigger finger had significantly higher odds and expedited rate of developing new-onset Dupuytren disease overall and undergoing subsequent treatment by fasciectomy compared with trigger fingers managed by other interventions.

This prospective randomized controlled study compared two injection techniques for trigger digit: either dorsal to the tendons in the proximal phalanx (PP group) or anterior to the tendons at the A1 pulley level (A1 group) in 106 patients. The primary outcome was the number of days to total relief of pain, stiffness and triggering, as recorded by the patients on visual analogue scales day-by-day for 6 weeks. The median number of days to complete symptom relief was 9 days in the PP group and 11 days in the A1 group for pain, 11 days and 15 days for stiffness and 21 and 20 days for triggering, respectively. Ninety-one per cent of all patients did not require any additional treatment, but 11 patients in both groups reported some remaining symptoms at 6 weeks. This study did not detect any significant difference between the two injection techniques, but provides detailed data of the rate and order of symptomatic relief after corticosteroid injection for this common condition.

We investigated the minimal clinically important difference (MCID) of the Michigan Hand Outcomes Questionnaire (MHQ) and the pain visual analogue scale (VAS-pain) after conservative treatment of trigger finger. This secondary analysis of a randomized controlled trial compared pain reduction, symptoms and functional improvement at 12 weeks. Patients included were at least 18 years old and able to complete MHQ and VAS-pain at enrolment and 12 weeks after treatment. The MCIDs of MHQ and VAS-pain were evaluated using a distribution-based, anchor-based and receiver operating characteristic (ROC) curve-based approach. Of the 117 patients, the MCIDs of MHQ and VAS-pain using a distribution-based approach were 5.3 and 0.6, respectively; applying ROC method were 23.5 and 2.5, respectively; and using anchor questions were 15 and 2, respectively. These MCID values by anchor-based method with a minimal difference of 15 for MHQ and 2 for VAS-pain are recommended as primary evidence to determine clinically significant improvement after conservative treatment of trigger finger.

This study aimed to identify the rates and risk factors for failure of percutaneous A1 pulley release. We retrospectively analysed patients who underwent percutaneous A1 pulley release between 2015 and 2019. We defined failure as (1) pain or discomfort at the final follow-up, (2) when open release or revision percutaneous release was performed, or (3) when steroid injections were administered three or more times for symptom control. A total of 331 digits from 251 patients were included. The mean follow-up duration was 47 months (minimum 24 months). Complete resolution was achieved in 287 cases (87%), but 21% required steroid injection before symptoms settled. There was failure in 44 cases (13%). Involvement of the index, middle and ring fingers was significantly different between the successful and failure groups. Percutaneous A1 pulley release has a long-term success rate of 87%. The failure rate was higher when the procedure was performed on the index, middle or ring fingers. Level of evidence: III [ABSTRACT FROM AUTHOR]

Abstract 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; I 2 = 73.1%; P

Even in the first application of patients with early complaints of trigger finger, pinch strength of the hand may be affected. Therefore, it is difficult to assess the change of strength as a result of treatment in this problem. In this study, we aimed to evaluate the change of strength taking into account both measured and expected pinch strengths before and after A1 pulley release surgery. Thirty fingers (9 thumbs, 12 middle, 8 ring and 1 index fingers) of 26 patients (17 women, 9 men) who underwent A1 pulley release were included into this study. The mean age of the patients was 53 (16–71). Tip-to-tip finger pinch strengths were measured pre-operatively and at 3 months postoperatively. The expected strengths were calculated using the values obtained from the healthy side and taking into account the dominance effect. In the analysis, pre-operative and postoperative measured strength/expected strength ratios were compared. The mean of measured pinch strength/expected pinch strength ratio was 0.91 ± 0.3 pre-operatively and 1.14 ± 0.3 postoperatively (p < 0.05). With the calculation method used in this study, it was found that there was a significant increase in the tip-to-tip pinch strength after surgical A1 pulley release for the trigger finger.

Abstract Background Trigger finger is a common disease with a lifetime prevalence of 2%. One of the frequently preferred non-surgical treatments is blinded injection around the A1 pulley. This study aims to compare the clinical results of ultrasound-guided and blinded corticosteroid injection in the trigger finger. Methods In this prospective clinical study, 66 patients who had persistent symptoms of a single trigger finger were included. Patients with similar baseline characteristics such as age, gender, triggering period, and comorbidities were randomized. 34 patients had ultrasound-guided (UG), and 32 had blinded injections (BG). QDASH, VAS, time to return to work, and complications were compared between the groups. Results The mean age was 52,66 (29–73) years. There were 18 male and 48 female patients. In the UG, the triggering resolved faster, returning to work was earlier, and the medication period was shorter (p 0.05). Conclusion Using ultrasound guidance for corticosteroid injections is more effective for treating trigger fingers than the blinded method, leading to better results and a faster return to work in the early stages of treatment.

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.

Background: The purpose of this study was to determine the occurrence of patients undergoing primary trigger finger release (TFR) that underwent ulnar superficialis slip resection (USSR) for decompression and to determine which digit was most commonly affected. Methods: A retrospective chart review was conducted of all cases of open TFR performed by a single surgeon. The following data were obtained: age, sex, laterality, affected digit, and consideration for USSR. All patients failed nonoperative treatment of at least 1 steroid injection. The occurrence of patients who underwent TFR and USSR and which digit(s) most commonly underwent USSR were determined. The average patient age that underwent USSR, frequency by sex, and relative occurrence of USSR in each digit were computed. Statistical calculations were conducted using χ2 analysis (P <.05). Results: A total of 911 primary open TFRs were performed in 631 patients over a 16-year period. A total of 20 TFRs in 20 patients underwent USSR (2.2%). The long finger was the most commonly affected digit (40%) that required simple decompression. Within all USSR cases, the long finger was the most commonly affected digit. The index finger was the second most affected (30%), and there were no cases in the small finger. Conclusions: This study determined the occurrence of primary TFR cases that underwent USSR, with the long finger being the most commonly affected digit. Surgeons may consider this additional procedure to perform a larger decompression than simple A1 pulley release alone. [ABSTRACT FROM AUTHOR]

Introduction. Orthopedic video contents published on YouTube are not scanned and do not go through an editorial evaluation process. It is important to determine the quality and content accuracy of health-related videos. Trigger finger is a common disease and the deterioration in quality of life. However, the quality, content and adequacy of YouTube videos as a source of information about this disease have not been evaluated. The aim of this study is to investigate the quality and adequacy of the medical content of the videos on YouTube about trigger finger disease. Methods. In September 2022, the phrase "trigger finger" was entered in the YouTube search bar and the 50 most watched videos were included in the study, provided that the language of the video was English. Who uploaded the videos, real or animated content, number of views, upload date, number of comments, number of like-dislikes and video length were recorded. 3 orthopedic surgeons and 1 hand surgeon watched the videos simultaneously and separately. JAMA, DISCERN and GQS scores were calculated. Results. Average length of 50 videos is 321 seconds, number of views is 244,150, number of days from upload date to evaluation date is 1,789 days, VPI was 94, view ratio was 300. The average scores of 4 different surgeons from the parameters used for the quality and relevance analysis of the videos: JAMA 2, DISCERN 36, and GQS 2. The scores of 4 different surgeons were statistically compatible with each other (p = 0.000). The interclass correlation coefficient (ICC) was 0.906 for the JAMA score, 0.889 for the DISCERN score, and 0.831 for the GQS score. Conclusions. YouTube videos about trigger finger were low quality and unreliable. In the light of our study and other studies, the possibility of high-quality and reliable videos for patients can be increased by the evaluation and inspection of videos presented by YouTube.

Objectives: This study retrospectively evaluated the effectiveness of percutaneous pulley release by our newly designed needle knife in terms of cure, relapse, and complication rates. Materials and Methods: Two hundred and fifty‑seven patients were allocated into male and female groups between October 2014 and September 2021. We included patients >15 years of age with a trigger finger (TF) (types II–VI). The primary outcome was the absence of a TF and pain‑free movement. In contrast, the secondary outcome included second‑time surgery and the number of complications such as infection and admission for antibiotics. Results: One hundred patients were male, and 157 patients were female. Males and females had mean ages of 62.45 ± 11.76 and 61.50 ± 8.57 years, respectively. The operative time was significantly longer in males than in females (7.88 ± 6.02 vs. 6.52 ± 3.74 min in males and females, respectively, P = 0.027). However, the percentages of diabetes mellitus and gout were the same in both groups. For the percutaneous methods with our needle knife, remission of the trigger was achieved in all cases. In addition, seven patients received revision and three patients with complications. After needle surgery, topical and joint pain scores were improved in both groups (from 5.09 ± 1.31 to 0.80 ± 1.56). Conclusion: The percutaneous methods with our needle knife displayed effectiveness. The cure rate was high, and the relapse rate was low. Further large‑scale clinical trials comparing percutaneous needle to open surgery for releasing the TF will be needed to confirm our results.

Pediatric trigger finger (PTF) is an acquired condition that is uncommon and anatomically complex. Currently, the literature is characterized by a small number of retrospective case series with limited sample sizes. This investigation sought to evaluate the presentation, management, and treatment outcomes of PTF in a large, multicenter cohort. A retrospective review of pediatric patients with a diagnosis of PTF between 2009 and 2020 was performed at three tertiary referral hospitals. Patient demographics, PTF characteristics, treatment strategies, and outcomes were abstracted from the electronic medical records. Patients and families also were contacted by telephone to assess the downstream persistence or recurrence of triggering symptoms. In total, 321 patients with 449 PTFs were included at a mean follow-up of 3.9 ± 4.0 years. There were approximately equal numbers of boys and girls, and the mean age of symptom onset was 5.4 ± 5.1 years. The middle (34.7%) and index (11.6%) fingers were the most and least commonly affected digits, respectively. Overall, PTFs managed operatively achieved significantly higher rates of complete resolution compared with PTFs managed nonsurgically (97.1% vs 30.0%). Seventy-five percent of PTFs that achieved complete resolution with nonsurgical management did so within 6 months, and approximately 90% did so within 12 months. Patients with multidigit involvement, higher Quinnell grade at presentation, or palpable nodularity were significantly more likely to undergo surgery. There was no significant difference in the rate of complete resolution between splinted versus not splinted PTFs or across operative techniques. Only 30% of the PTFs managed nonsurgically achieved complete resolution. Splinting did not improve resolution rates in children treated nonsurgically. In contrast, surgical intervention has a high likelihood of restoring motion and function of the affected digit. Therapeutic IV. [ABSTRACT FROM AUTHOR]

Abstract Background Trigger thumb is a pathologic condition of the digital pulleys and flexor tendons. To find a cutoff value of the cross-sectional area ratio of specific parts of the flexor pollicis longus tendon to diagnosis trigger thumb in the high-frequency ultrasound examination. Methods We evaluated 271 healthy volunteers and 57 patients with clinical diagnosis of trigger thumb. The cross-sectional area of the metacarpophalangeal joint of flexor pollicis longus tendon (C1) and the cross-sectional area of the midpoint of the first metacarpal of flexor pollicis longus tendon (C2) were analyzed. Results There is no difference between gender, age and left and right hands in the ratio of C1 to C2 (C1/ C2). The mean of C1/ C2 in the healthy thumb was 0.983 ± 0.103, which was significantly smaller in comparison to the diseased thumb (P

Our study purpose was to report the clinical application of five different pharmacopunctures (Sweet BV, Scolopendrae Corpus, Chukyu, Cervi Parvum Cornu, and Hominis Placenta) for trigger finger. A patient was admitted to Ba-reun-mom S Korean Medicine Clinic and diagnosed with trigger finger. Because the effects of each pharmacopuncture have been confirmed in various acute to chronic cases, we treated a patient diagnosed with trigger finger using pharmacopunctures Sweet BV and Scolopendrae Corpus at the acute phase, Chukyu pharmacopuncture at the acute to chronic phase, and pharmacopunctures Cervi Parvum Cornu and Hominis Placenta at the chronic phase. This case was measured and assessed by Quinnell’s classification of triggering and visual analogue scale (VAS) scores. After treatment, the patient’s fifth finger pain and function were improved. The VAS score decreased from 5 to 0. The Quinnell’s classification of triggering score decreased from 2 to 0. This case indicated that a patient with trigger finger could be treated by five pharmacopuncture treatments according to the treatment regimen and disease progress.

Finger deformities are a common reason for medical observation in children. Subtle clinical differences can have a significant impact on the diagnosis and treatment of these patients. Identification of the basic diagnostic and treatment principles of trigger thumb, trigger finger, and clasped thumb is of paramount importance to all general practitioners, pediatricians, and orthopedic surgeons who are involved in the care of children. The purpose of this article is to review the most important concepts regarding these important topics, focusing on etiology, epidemiology, clinical presentation, diagnosis, treatment and prognosis.

Background: Trigger finger is a common disease with a lifetime prevalence of 2%. One of the frequently preferred non-surgical treatments is blinded injection around the A1 pulley. This study aims to compare the clinical results of ultrasound-guided and blinded corticosteroid injection in the trigger finger. Methods: In this prospective clinical study, 66 patients who had persistent symptoms of a single trigger finger were included. Patients with similar baseline characteristics such as age, gender, triggering period, and comorbidities were randomized. 34 patients had ultrasound-guided (UG), and 32 had blinded injections (BG). QDASH, VAS, time to return to work, and complications were compared between the groups. Results: The mean age was 52,66 (29–73) years. There were 18 male and 48 female patients. In the UG, the triggering resolved faster, returning to work was earlier, and the medication period was shorter (p < 0.05). A total of 17 patients who had diabetes mellitus received re-injections, 11 of which were in BG and 6 in UG (p < 0.05). Although statistically significantly lower scores were obtained in UG at the 1st and 4th weeks in the QDASH and VAS scores (p < 0.05), at the 12th and 24 weeks, there was no significant difference (p > 0.05). Conclusion: Using ultrasound guidance for corticosteroid injections is more effective for treating trigger fingers than the blinded method, leading to better results and a faster return to work in the early stages of treatment.

Background: None of the commonly cited risk factors for chronic hand conditions such as trigger finger (TF) delivers a convincing explanation for the striking differences among affected fingers or gender predominance. Hence, we aimed to investigate further possible TF-associated risk factors such as extrinsic mechanical constrictions caused by wedding rings. Methods: A retrospective data analysis was conducted at a single centre. Patients operated on for release of the A1 pulley from 2005 to 2019 were included. Exclusion criteria involved multiple TF and unknown marital statuses. Case attribution of patients was made with surgical A1-pulley release of the ring finger vs. controls (all other affected single fingers) with marital status equal to "married" as a risk factor. Differences in frequencies were tested using Fisher's exact test and risk factors expressed as odds ratios (OR). Models adjusting for age were analysed by logistic regression. Results: In our 188-patient cohort (60 male/128 female), the three most affected (92% of cases) were the thumb (n = 69), ring (n = 52), and middle finger (n = 52). When comparing the affected ring fingers to all other digits collectively, we found a significantly higher number of ring fingers in the married group (OR = 3.0, 95% CI: 1.37–6.7 p = 0.005). Although marital status depended strongly on age, the odds ratio remained almost unchanged after adjusting for age. Conclusions: We conclude that any form of extrinsic mechanical constriction of fingers associated with rings increases the risk for developing one of the most common hand conditions worldwide; this may be relevant for reassessing disease-related risk. Level of evidence: Level IV, risk/prognostic. [ABSTRACT FROM AUTHOR]

Background: With lack of regulation and incentivisation on YouTube for high-quality healthcare information, it is important to objectively evaluate the quality of information on trigger finger – a common condition for hand surgeon referral. Methods: YouTube was queried (11/21/2021) for videos on trigger finger release surgery. Videos were excluded if they were about unrelated topics or not in English. The most viewed 59 videos were categorised by source as physician or non-physician. Two independent reviewers quantified the reliability, quality and content of each video, with inter-rater reliability assessed using Kohen's Kappa test. Reliability was assessed using the Journal of the American Medical Association (JAMA) score. Quality was assessed using the DISCERN score with high-quality videos defined as those with scores in the sample upper 25th percentile. Content was assessed using the informational content score (ICS) with scores in the sample upper 25th percentile indicating more complete information. Two-sample t-tests and logistic regression were used to assess variations between sources. Results: Videos by physicians had higher DISCERN quality (42.6 ± 7.9, 36.4 ± 10.3; p = 0.02) and informational content (5.8 ± 2.6, 4.0 ± 1.7; p = 0.01) scores compared to those by non-physician sources. Videos by physicians were associated with increased odds of high-quality (Odds Ratio [OR] 5.7, 95% Confidence Interval [95% CI] 1.3–41.3) and provided more complete patient information (OR 6.3, 95% CI 1.4–48.9). The lowest DISCERN sub-scores for all videos were discussion of the uncertainties and risks associated with surgery. The lowest ICS for all videos were in the diagnosis of trigger finger (11.9%) and non-surgical prognosis (15.3%). Conclusions: Physician videos have more complete and higher quality information on trigger finger release. Additionally, discussion of treatment risks, areas of uncertainty, the diagnostic process, non-surgical prognosis and transparency on references used were identified as lacking content. Level of Evidence: Level III (Therapeutic) [ABSTRACT FROM AUTHOR]

Background: Corticosteroid injections have proven benefit in the treatment of symptomatic trigger finger; however, the immune system and tissue repair modulating properties of corticosteroids justify further consideration in surgical candidates. The aim of this study was to assess the relationship between corticosteroid injections and postoperative infection in trigger finger release. Methods: A single-center retrospective review was conducted of patients seen from 2010 to 2019 to identify those who underwent trigger finger release with subsequent antibiotic prescription for chart-documented wound infection. A demographic matched cohort of 100 patients was identified for comparison. Preoperative corticosteroid injection history including timing, frequency, and dose was collected for all patients. Patient demographics, comorbidities, and presence of postoperative infection were collected from patient medical records. Superficial infection was defined as those requiring antibiotics for resolution without return to the operating room; deep infection was defined as infections that required irrigation and debridement. Results: Of 3234 patients who underwent trigger finger release, 58 (1.8%) were identified with postoperative infections, 6 (0.2%) of which were deep infections. History of corticosteroid injection was significantly more common in patients with postoperative infection. Compared with an age-matched, gender-matched, and body mass index–matched cohort, patients with postoperative infection had significantly increased rate of diabetes mellitus at 34.5% to 19% (P =.04) Conclusions: While corticosteroid injection in the preoperative period is associated with a higher rate of postoperative infection, the time before surgery and the corticosteroid dose do not appear to have an effect.

Aim: This study aimed to use high-frequency ultrasound guidance to compare the efficacy of percutaneous release combined with intra-tendon sheath injection (PR-ITSI) and percutaneous release only (PR-ONLY) in the treatment of adult trigger finger (TF) patients. Materials and methods: A total of 48 patients were randomly divided into PR-ITSI group and PR-ONLY group. The thickness of the A1 pulley was measured prior to surgery and 1-year after surgery. Visual Analogue Scale (VAS) score and Patient Global Impression of Improvement (PGI-I) scale score of affected fingers were evaluated at 1 day, 1 month, and 1 year after surgery. Results: The overall difference of VAS score between the two groups after treatment was statistically significant (p<0.001), while the VAS scores gradually decreased in both groups at different time-points after treatment. The VAS scores in the PR-ITSI group at 1 day and 1 month after surgery were 1.475 and 0.904 (p<0.001), respectively, which were lower than those in the PR-ONLY group. Different treatment methods had no effect on the VAS score at 1 year after surgery (p=0.055). The thickness of the A1 pulley at 1 year after surgery was lower than that before surgery (p<0.001), whereas there was no significant difference in A1 pulley thickness between the two groups (p=0.095). The rate of PGI-I scale improvement by one grade at 1 day, 1 month, and 1 year after surgery in the PR-ITSI group was 15.322 times (95%CI: 4.466-52.573, p<0.001), 14.807 times (95%CI: 2.931-74.799, p=0.001), and 15.557 times (95%CI: 1.119-216.307, p=0.041), respectively, than that in the PR-ONLY group. Conclusion: Ultrasound-guided PR-ITSI is superior to PR-ONLY in the VAS score and PGI-I scale for adult TF patients. [ABSTRACT FROM AUTHOR]
