Ultrasonography is the most important development that has been used in recent years during the diagnosis and treatment of musculoskeletal disorders. In this case report, the diagnosis process will be discussed due to ultrasonographic imaging of the sesamoid bone which is not seen in radiographic evaluation, which is the first step we used to image bone structure in a patient who diagnosed with trigger finger.

Our aim in this study was to determine the frequency of Trigger finger, De quervain tenosynovitis and Dupuytren contracture in patients who underwent Idiopathic carpal tunnel release. The frequencies of trigger finger (TF), De Quervain tenosynovitis (DQ), and Dupuytren contracture (DC) on the same or contralateral extremity were evaluated in 430 patients who underwent surgery with a diagnosis for idiopathic carpal tunnel syndrome (ICTS) from January 2008 to August 2017. The mean age of patients was 54.6 (range, 40-68), and 348 were female while 82 were male. We identified 42 cases with TF (9.76%), 7 cases with DQ (1.62%), and 10 cases with DC (2.32%). We believe that our data could provide insight for the evaluation of the Turkish population. [Med-Science 2017; 6(4.000): 729-732]

Background and objective: The characteristics of diabetic foot disease are well documented in Erbil city; henceforth it would be appropriate to evaluate the problem of diabetic hand syndrome in this environment and to assess the frequency and the most important clinical and biochemical risk factors for the development of these complications. Methods: This is an observational case-control study done over a period of one year. A total of 100 consecutive patients with type 2 diabetes mellitus were enrolled and described as cases. One hundred age- and sex-matched nondiabetic individuals were taken in the control group; all were examined and then underwent the appropriate investigations. Results: Of the total 100 diabetic patients, 63% had macrovascular complications and 60% had one or more hand disorders. Limited joint mobility (47% vs. 18%, respectively; P = 0.0001) and Dupuytren’s contracture (16% vs. 2%, respectively; P = 0.001) were significantly higher in type 2 diabetes mellitus patients than in the controls, but not trigger finger. These hand soft-tissue changes correlated significantly with poor glycemic control. Conclusion: This study shows a high prevalence of hand disorders in diabetic patients with the limited joint mobility being the most common hand disorder. The hand soft tissue changes are under recognized in diabetic patients, occurring in 60% of the cases. We recommend that physicians should consider examining the periarticular region of the joints in the hands in each diabetic patient.

Trigger finger is a common pathologic condition of the digital pulleys and flexor tendons in the hand. The key clinical finding is a transient blockage of the digit when it is flexed with subsequent painful snapping when it is extended. Imaging is a helpful guide for establishing the severity of the disease, identifying the underlying cause, and deciding the appropriate management. This narrative review aims to recall the anatomic and pathologic bases and describe the ultrasound features of trigger finger, also including common ultrasound findings and complications after therapy. Ultrasound enables an accurate static and dynamic evaluation of trigger finger as well as a comparison with the adjacent normal digits and thus should be considered the radiologic modality of first choice for its diagnosis.

The purpose of this study was to compare the clinical outcomes of A1 pulley release with ulnar superficialis slip resection (group A) and simple A1 pulley release (group B) in trigger finger with flexion contracture of the proximal interphalangeal (PIP) joint. From January 2016 to December 2019, the 2 surgical procedures were performed alternately every year for trigger fingers with preoperative PIP joint flexion contractures of ≥10°. Twenty-six fingers in group A and 29 fingers in group B that were followed up for >1 year were reviewed in this retrospective study. The visual analog scale (VAS) score; Disabilities of the Arm, Shoulder, and Hand (DASH) score; degree of PIP joint flexion contracture; grip strength; and pinch strength were measured after surgery and compared. The differences in postoperative PIP joint flexion contracture between groups were <4° at 2 and 6 weeks, and there were no clinically relevant differences at 6 weeks and 12 months. At the final follow-up, PIP joint flexion contractures of 5° were observed in 2 fingers in each group. The difference in VAS scores between groups was less than half of a point until 3 months, and there were no clinically relevant differences at 6 weeks and 12 months. The DASH score did not show any difference between groups at the final follow-up. There were clinically relevant differences in the grip and pinch strengths between groups at 6 weeks. However, there were no clinically relevant differences at the final follow-up. Proximal interphalangeal joint flexion contracture measurements and clinical scores did not differ between groups at the final follow-up. Therefore, we recommend use of a simple A1 pulley release, which is simpler than an A1 pulley release with ulnar superficialis slip resection, in cases of trigger finger with PIP joint flexion contracture.

Trigger finger is a common yet vastly understudied fibroproliferative hand pathology, severely affecting patients’ quality of life. Consistent trauma due to inadequate positioning within the afflicted finger’s tendon/pulley system leads to cellular dysregulation and eventual fibrosis. While the genetic characteristics of the fibrotic tissue in the trigger finger have been studied, the pathways that govern the initiation and propagation of fibrosis are still unknown. The complete gene expression profile of the trigger finger has never been explored. Our study has used the Nanostring nCounter gene expression assay to investigate the molecular signaling involved in trigger finger pathogenesis. We collected samples from patients undergoing trigger finger (n = 4) release surgery and compared the gene expression to carpal tunnel tissue (n = 4). Nanostring nCounter analysis identified 165 genes that were differentially regulated; 145 of these genes were upregulated, whereas 20 genes were downregulated. We found that several collagen genes were significantly upregulated, and a regulatory matrix metalloproteinase (MMP), MMP-3, was downregulated. Bioinformatic analysis revealed that several known signaling pathways were dysregulated, such as the TGF-β1 and Wnt signaling pathways. We also found several novel signaling pathways (e.g., PI3K, MAPK, JAK-STAT, and Notch) differentially regulated in trigger finger. The outcome of our study helps in understanding the molecular signaling pathway involved in the pathogenesis of the trigger finger.

In this study mid- and long-term outcomes of the cases with trigger finger we treated using Admix NoKorTM have been presented. Percutaneous release procedures were applied for 24 fingers of 22 (19 female, 3 male patients; mean age, 57; range, 39-72) patients between May 2009 and May 2011. Preoperatively US was performed so as to confirm the presence of trigger finger. Diameters of the tendons of the affected and intact hands measured using US, were compared so as to be able to demonstrate thickening of the tendon of the trigger finger. The patients were monitored for an average period of 25.2 (range, 14-36) months. During surgery, clinically loss of the catching sensation was observed. In two patients percutaneous trigger finger release failed, so we have to proceed with open surgery. During open surgery, we observed longitudinal wounds on the tendon. One patient developed unilateral radial digital nerve damage. Percutaneous release of the trigger finger using Admix NoKorTM 16-G gauge needle can be preferred in the treatment of trigger finger. Trigger finger of the first digit requires more attentive approach and one should be aware of the complications. If required open surgery can be preferred. [Med-Science 2017; 6(3.000): 551-6]

Trigger finger is a very frequent problem identified by rheumatologists. It comes in association with diabetes mellitus and rheumatoid arthritis but also in patients that put their fingers to high mechanical pressure daily. In the incipient stages is not painful and much more difficult to be recognized – both in this phase and in the subsequent, the MSUS offer valuable diagnostic information. Corticoid injection in the affected area represents the best option for trigger fingers with recent onset. The technique should be done under US guidance to maximize the results. Surgery and other conservative options might not possess some benefit to risk ratio in this case.

Percutaneous release (PR) of the A1 pulley is a quick, safe, and minimally invasive procedure for treating trigger fingers. The purpose of this study is to identify if PR with additional steroid injections can shorten the recovery to reach unlimited range of motion. Between January 2013 and December 2013, we included 432 trigger fingers with actively correctable triggering or severer symptoms without previous surgical release or steroid injections from two hand clinic offices (A and B). The same experienced surgeon performed PR at the office. Patients from Clinic A received PR with steroid injections and those from Clinic B received PR without steroid injections. Patients returned for follow-up 1 week, 6 weeks, and 12 weeks after the procedure. Between the steroid group and the nonsteroid group, there is no significant difference in the mean time for patients to return to normal work and the rate of residual extensor lag. Middle fingers showed a 5.09-fold chance of having a residual extensor lag over that of the other fingers. High grade trigger fingers recovered more slowly than low grade ones. The success rate of a 12-week follow-up was 98.4%. There was no significant difference between the steroid group (97.5%) and the nonsteroid group (99.1%). PR can treat trigger fingers effectively, but additional steroid injection does not provide more benefit. Some fingers showed temporary extensor lag, especially in middle fingers and high grade trigger fingers, but 85% of those will eventually reach full recovery after self-rehabilitation without another surgical release.

Objective: The purpose of this study was to evaluate the efficacy of ultrasonography-guided percutaneous A1 pulley release with the needle knife for trigger finger.Methods: The prospective study included 21 patients (21 fingers) who underwent blind release with the needle knife and 20 patients (20 fingers) who underwent ultrasonography-guided release with the needle knife. The thickness and width of A1 pulley, clinical grade before and after release, complications, and operation time were compared between the groups.Results: The results showed that the ultrasonography-guided group had significantly better grade postoperatively and reached to 100% complete release in one time compared to the blind group (p < 0.05). Moreover, no any complications had been happened in the ultrasonography-guided group. A relatively longer operation time of the ultrasonography-guided group was observed compared to the time of the blind group.Conclusions: The needle knife is a very good tool for release of triggering fingers. Ultrasound provides a direct and precise visualization of the thickness, width and location of A1 pulley lesion. The combined use of ultrasound and the needle knife can achieve the best result for trigger finger. Moreover, the combination changes the traditional opinion and operator-dependent mode that were once widely adopted in the hospital of Chinese Medicine.

Objectives This study aims to investigate the negative prognostic indicators of pediatric and adult trigger finger surgery patients concerning complications, recurrence, and satisfaction. Methods A retrospective study was conducted on 61 patients with a total of 91 trigger fingers, including 31 in children and 30 in adult patients, all of whom were treated using a standardized surgical technique. The study considered several demographic and clinical factors, including age, gender, dominant hand, body mass index, occupation, history of trauma, single or multiple finger involvement, staging according to Green classification, diabetes mellitus, comorbidities, recurrence, revision surgery, utilization of non-surgical treatment methods, need for rehabilitation after surgery, time to return to work, the time interval from clinic initiation to the surgery, satisfaction and the duration of the follow-up period. In addition, the quick version of the disabilities of the arm, shoulder, and hand (QDASH); and the visual analog scale (VAS) were used to assess patients' data. Results In adult patients, a statistically significant relationship was observed between the increasing grade of the Green stage and complication rate (p<0.001), recurrence (p<0.001), and lower satisfaction (p<0.001). No statistically significant relationship was identified between Green's classification and complications (p=0.129), recurrence (p=0.854), or satisfaction (p=0.143) in pediatric patients. While a statistically significant relationship existed between the time interval from clinic initiation to surgery and complications (p=0.033) in adult patients, no significant relationships were observed for recurrence or satisfaction. Conversely, there was no statistically significant relationship between the time interval from clinic initiation to surgery and complications, recurrence, or satisfaction in pediatric patients. Conclusion This study demonstrates that increasing the grade of the Green stage and duration of symptoms before surgery were the substantial factors contributing to prognosis in adult patients but not in pediatric patients. These findings can assist physicians during patients' treatment management. We suggest that physicians consider these factors for patients' satisfaction., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Köroğlu et al.)

Diabetes mellitus is a metabolic disease that results in long-term hyperglycemia. Among the many long-term complications associated with diabetes, manifestations in the hand include Dupuytren's contracture, trigger finger, compressive neuropathies, and infections. These conditions can have a profound impact on a patient's quality of life, highlighting the importance of timely recognition and treatment of these manifestations. This review aims to provide updated information regarding the incidence and outcomes of these clinical manifestations in the diabetic versus nondiabetic population. A systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was performed. The literature search included the use of PubMed and Ovid databases to find relevant articles that were then selected based on an inclusion criterion that required level 4 evidence. Diabetes mellitus results in an increased incidence of Dupuytren's contracture, trigger finger, carpal tunnel syndrome, cubital tunnel syndrome, and hand infections. Dupuytren's, trigger finger, and carpal tunnel syndrome all had similar outcomes, while diabetic patients had worse outcomes related to infections. There was a lack of data regarding the effect of diabetes on cubital tunnel syndrome. Future studies should be performed to analyze the effects of diabetes mellitus on hand manifestations, particularly regarding the outcomes of diabetic patients with cubital tunnel syndrome., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Trigger finger release (TFR) is a common hand surgery, historically performed using a tourniquet. Recently, wide-awake local anesthesia no tourniquet (WALANT) has gained popularity due to ostensible advantages such as improved patient pain, satisfaction, lower rate of complications, and decreased cost. This systematic review compares outcomes of WALANT for TFR with local anesthesia with a tourniquet (LAWT). MEDLINE, Embase, CINAHL, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched. All English-language peer-reviewed randomized and observational studies assessing TFR in adults were included. Quality of evidence was assessed with the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Eleven studies (4 randomized controlled trials, 7 observational) including 1233 patients were identified. In the WALANT group, pain on injection was statistically nonsignificantly lower (mean difference [MD]: -1.69 points, 95% confidence interval [CI] = -4.14 to 0.76, P = .18) and postoperative pain was statistically lower in 2 studies. Patient and physician satisfaction were higher and analgesic use was lower in WALANT. There were no significant differences between groups for functional outcomes or rates of adverse events. Preoperative time was longer (MD: 26.43 minutes, 95% CI = 15.36 to 37.51, P < .01), operative time similar (MD: -0.59 minutes, 95% CI = -2.37 to 1.20, P = .52), postoperative time shorter (MD: -27.72 minutes, 95% CI = -36.95 to -18.48, P < .01), and cost lower (MD: -52.2%, 95% CI = -79.9% to -24.5%) in WALANT versus LAWT. The GRADE certainty of evidence of these results ranges from very low to low. This systematic review does not confirm superiority of WALANT over LAWT for TFR due to moderate to high risk of bias of included studies; further robust trials must be conducted., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Patients who have had a corticosteroid injection at the surgical site within 90 days of trigger finger release (TFR) or carpal tunnel release (CTR) have an elevated risk of postoperative infection. Currently, it remains unknown if a preoperative injection in proximity to the surgical site for a separate complaint alters the risk of a postoperative infection., Methods: A retrospective chart review was performed on all patients who underwent TFR or CTR between 2010 and 2022. Patients who had a corticosteroid injection at or near the surgical site within 90 days of surgery were included. Outcome measures included uncomplicated healing, superficial infection requiring antibiotics, and deep infection (DI) requiring surgical debridement., Results: There were 564 cases in which a corticosteroid injection was performed within 90 days of TFR or CTR. Superficial infections occurred in 12 (2.1%), and DIs occurred in 6 (1.1%) cases. There was no significant difference in infection rates between the two groups relative to the location of the injection nor timing of the injection (0-30, 31-60, or 61-90 days prior to surgery)., Conclusions: Patients who had an injection at the surgical site within 90 days of TFR or CTR had an elevated rate of postoperative infection compared with published rates in the literature. This study is unique in that preoperative injections at an adjacent site in the palm also correlated with an elevated rate of infection, similar to patients who had an injection at the surgical site., Level of Evidence: Level 4., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Maintaining intraoperative haemostasis is crucial when conducting wide-awake hand surgeries, this is particularly to improve visibility which will improve patient's outcome. There are various methods that could achieve the aforementioned, some of which is wide awake local anaesthesia without tourniquet (WALANT) or Tourniquet alongside sedation. Each method has its own benefits and drawbacks. This study primarily focuses on Carpal Tunnel Syndrome and Trigger Finger release. A comprehensive literature review was conducted through PUBMED, Scopus, google scholar, and web of science. A total of 45 articles were included in the study. We aimed to assess whether the literature supports the use of a tourniquet alongside sedation, or only local anesthesia and epinephrine in wide awake hand surgeries. Moreover, we aimed to highlight the benefits and drawbacks of using a tourniquet, and determine the patient population most likely to benefit from tourniquet application., Competing Interests: The authors declare that there is no conflict of interest.

Background: Considerable evidence supports corticosteroid injection as an effective treatment for trigger finger. One common side effect, the flare reaction, is a well-documented phenomenon of increased pain following steroid injections. Its incidence and intensity may be related to steroid composition. The purpose of this study was to determine whether betamethasone and methylprednisolone injections for trigger fingers have differing intensity of pain or incidence flare reaction., Methods: Patients with symptomatic trigger finger were recruited during their hand surgery visits. Patients were randomized into 2 treatment groups: betamethasone (40 mg) and methylprednisolone (6 mg) mixed with lidocaine 1%. Treatment group assignment was blinded to the patients and investigators. Visual analog scale pain measurements were taken prior to injection, 5 minutes postinjection, and daily thereafter for 7 days., Results: Sixty-four patients were randomized into the 2 treatment groups. Patients in the betamethasone group reported slightly higher baseline pain compared with the methylprednisolone group, but lower pain on day 1. None of the following days showed a statistically significant difference., Conclusions: The incidence of flare and severe flare reactions of betamethasone injections for trigger finger management was roughly double that of methylprednisolone, but this difference was not statistically significant. Further studies are required to evaluate the relative course of nonflare postinjection pain for different corticosteroid injections for trigger finger injections., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Trigger finger is one of the most common pathologies of the finger flexor mechanism. Previous studies have shown the value of ultrasound-guided percutaneous tenolysis. The aim of this study was to compare the efficacy and safety of anterograde versus retrograde percutaneous ultrasound-guided tenolysis., Materials and Methods: This was a comparative cadaver study performed between December 2021 and April 2022 in France, with 40 fresh cadaver fingers. Thumbs were excluded. A single surgeon performed 20 ultrasound-guided anterograde releases and 20 ultrasound-guided retrograde releases, using a second-generation minimally invasive surgical knife, and a multipurpose linear ultrasound transducer. The primary endpoint was the success of ultrasound-guided release, defined as complete opening of the A1 pulley along its entire length., Results: The success rate was 90% in the retrograde group and 95% in the anterograde group (non-significant difference: p = 0.56). There was no significant difference in superficial flexor tendon slip injuries or partial A2 pulley injuries. There were no neurovascular pedicle lesions., Conclusion: The choice of anterograde or retrograde ultrasound-guided tenolysis should be left to the surgeon's discretion., (Copyright © 2023 SFCM.

Indroduction: Trigger finger is very common in the population, with a life-threatening risk of developing the disease of 2.6% in the general population and increasing to 4 to 10% in diabetics. Since there is no standard gold of surgical treatment and there is still controversy in this, it is important to evaluate the results of the different surgical techniques. The objective of this study is to evaluate postoperative results of both surgical techniques in patients with follow-up of 1 to 12 months postoperative. Material and methods: It is a prospective, longitudinal, descriptive and observational study carried out in a period from January 2015 to December 2017. Postoperative open (group 1) and percutaneous needle (group 2) patients were included. All patients were reviewed and surveyed by telephone. The comparison results of both techniques were analyzed using X2 for parametric results and by the Fisher test for nonparametric results. Results: It was found that patients in group 2 expressed greater satisfaction, where 21.8% (n = 12) were fully satisfied with the percutaneous procedure, unlike those in group 1 where total satisfaction was only manifested at 3.8% (n = 2). Conclusions: In this study we can conclude that both techniques are effective for the treatment of trigger finger, with percutaneous needle release offering the highest degree of satisfaction in patients.

Objectives: The aim of this study was to investigate the correlation between hypervascularization of the first annular (A1) pulley on color Doppler imaging of trigger finger and patients' backgrounds. Methods: A total of 148 trigger digits from 144 patients were studied with ultrasound at the time of initial diagnosis. We observed the A1 pulley at the level of the metacarpophalangeal joint in a transverse image and noted the presence or absence of a signal in the A1 pulley on color Doppler imaging. Patients' ages, sexes, clinical grades, symptom durations, prevalence of interphalangeal joint contracture, and visual analog scale pain scores were compared between the groups with positive and negative Doppler findings. Results: The 144 patients included 45 men and 99 women. Sixty‐one of 148 digits (41%) showed positive Doppler findings in the A1 pulley. Patients' ages and visual analog scale scores in the Doppler‐positive group were slightly greater than those in the Doppler‐negative group (P = .03; P < .01, respectively). The digit with positive Doppler findings tended to be categorized into a severer grade and into the group with a shorter symptom duration (P < .01 for both). Conclusions: Hypervascularization of the A1 pulley tended to appear in an earlier period after the patients had become aware of symptoms, as frequently as their symptoms became severe, in conjunction with higher pain scores. Doppler imaging of the A1 pulley might help in better understanding patients' conditions. [ABSTRACT FROM AUTHOR]

Surgical treatment of carpal tunnel syndrome (CTS) was recently started in our department, and we noticed that the development of trigger finger (TF), with which neurosurgeons are generally unfamiliar, is not rare after such treatment. We summarized the clinical and pathogenetic aspects of TF and retrospectively analyzed the medical records of all 39 patients who underwent CTR in our department to investigate the occurrence of TF. In 39 patients with CTS, 46 surgical interventions were performed in our department. All surgical procedures were carried out by open release of the transverse carpal ligament under local anesthesia infiltration, but the distal forearm fascia was not released. The mean postoperative follow-up period was 21.1 ± 16.8 months. TF after CTR occurred in nine hands of eight patients (9 of 46 hands, 19.6%). The mean interval between CTR and TF onset was 5.3 ± 2.8 months. TF after surgical treatment of CTS is not rare; therefore, surgeons who treat CTS should understand the clinical features of TF and carefully assess affected patients, particulary at presentation and within 6 months postoperatively.

Retrospective comparative study. Trigger finger and carpal tunnel surgery are common, but not without complications including pain and edema, which are treated with hand therapy (HT). There are limited data for the outcomes of multiple trigger finger releases (MTFRs) or combined trigger finger and carpal tunnel surgery and the subsequent need for HT. Based on our hypothesis that patients with more than 1 procedure may benefit from an early HT visit, we performed this study to compare the frequency of HT orders after single trigger finger releases (STFRs) and MTFRs and determine the reasoning for variation in the rate of HT orders after releases. Subjects receiving either an STFR or an MTFR were identified. Patient-reported outcomes were recorded preoperatively and 2 weeks postoperatively. One hundred fifty-nine eligible subjects were identified; 33 MTFRs and 126 STFRs. MTFR subjects were prescribed postoperation HT at a higher rate compared with STFR subjects (66.7% vs 34.1%; P <.001). Of the HT subjects, MTFR subjects received prescriptions for edema management at a significantly higher rate compared with STFR subjects (P =.02). Patients with soft tissue dissection, edema, and stiffness would most likely benefit from HT services. It is important to identify these at-risk subpopulations to potentially alter their postoperative trajectories and improve outcomes. Higher rates of referral to HT occur when there are multiple concomitant hand procedures. This suggests surgeons triage HT services based on need. Policies that disallow postoperative therapy will have a greater impact on patients with these indications. • This observational study compared hand therapy (HT) referral patterns based on whether a single trigger finger release or multiple trigger finger release was performed. • Multiple trigger finger release patients were prescribed postoperative HT at twice the rate compared with single trigger finger release patients. • Referral to HT appears to be dependent on surgical indications and clinical presentation, with more complex patients being referred for services. • Evidence-based referral algorithms may enhance the efficiency or outcomes of care.

Surgical treatment of trigger finger involves release of A1 pulley. Some authors have theorized that the loss of A1 pulley can lead to ulnar subluxation of flexor tendons, which can be prevented by release of A1 pulley radially, even in a nonrheumatoid hand. However, there is no evidence in literature to either support or oppose this hypothesis. Occasionally, difficulty is encountered to precisely identify where A1 ends and A2 begins. While incomplete release of A1 can cause relapse of triggering, release of substantial A2 can cause bowstringing. Knowledge of the safe limit of concomitant A2 release is beneficial. The study was conducted in 12 cadaver upper extremity specimens. A1 pulleys of 48 fingers were divided at the radial (24 fingers) or ulnar (24 fingers) attachment. A 20lb traction force was applied on the flexor tendons. Any subluxation or bowstringing was noted. The experiment was repeated following serial release of the A2—initially 25%, followed by 50% and 100%. No bowstringing or subluxation was noted when A1 pulley was opened, either by radial or ulnar incision. The same was true for A1 + 25% A2 release. When A1 + 50% A2 pulley were released, bowstringing was observed in 3/48 fingers. When A1 + 100% of the A2 pulley were released, bowstringing occurred in all cases. The location of incision for release of the A1 pulley has no effect on bowstringing or tendon subluxation. Release of additional 25% of the A2 pulley can be performed safely, which corresponds to the level of palmar digital crease. [ABSTRACT FROM AUTHOR]

Background: Long-standing trigger finger can lead to proximal interphalangeal (PIP) joint flexion contracture. In the present study, we present the clinical outcome of percutaneous release with finger splinting for trigger finger with PIP joint flexion contracture prospectively. Methods: We compared outcomes in patients with trigger fingers combined with proximal interphalangeal joint flexion contracture treated by percutaneous release therapy regimen alone (group I) or percutaneous trigger finger release combined with finger splint (group II) during January 2011 and May 2016 with 6 months follow up. Results: Sixty-five patients were randomly allocated to group I (35 patients) or group II (30 patients). Symptoms of locking sensation and pain over the A1 pulley were improved in all patients. The patients in group II showed significantly greater improvements in the flexion contracture angles of proximal interphalangeal joint at post-operative 3 months later (group I, 9.4° ± 4.1°; group II, 27.8° ± 4.6°) and at 6 months later (group I, 15.1° ± 5.2°; group II, 35.7° ± 5.3°) relative to group I. In group II, 25 fingers achieved near full extension (< 10° contracture) after 6 months. Conclusions: Percutaneous release combined with finger splint is regarded as a useful therapy to speed recovery of trigger finger with proximal interphalangeal joint flexion contracture.

Purpose: To determine the efficacy and safety of corticosteroid injection for trigger finger by performing a meta-analysis of all relevant studies. Methods: PubMed, EMBASE, and Cochrane Library databases were searched for randomized controlled trials (RCTs) comparing corticosteroid injection with other treatments for trigger finger. Pooled summary estimates for outcomes, including success rate, relapse rate, visual analogue score (VAS) and complications, were calculated as standardized mean difference (SMD) or relative risk (RR) either on a fixed- or random-effect model via Stata 12.0 software. Results: Ten literatures involving 806 patients (387 in corticosteroid injection group and 419 in control group) were included. Pooled analysis showed there were no differences in the success rate, VAS and complications between patients undergoing corticosteroid injection and others. However, the relapse rate was significantly higher in patients treated with corticosteroid injection than that of other treatments (RR = 19.53, 95% CI = 6.23–61.19). Subgroup analysis indicated the efficacy of corticosteroid injection was superior to other non-surgical treatments (success rate: RR = 1.54, 95% CI = 1.01–2.35), but inferior to surgery (success rate: RR = 0.55, 95% CI = 0.48–0.63; relapse rate: RR = 21.15, 95% CI = 6.06–73.85; VAS: SMD = 3.49, 95% CI = 2.84–4.14). Conclusions: Corticosteroid injection may be an effective strategy for management of trigger finger, although surgery may be needed for some patients due to recurrence. [ABSTRACT FROM AUTHOR]

The current paper presents în detail the defining elements of the etiopathogeny and surgical treatment of the trigger finger. The objective of the study is to identify the particular elements that can influence the post-operative prognosis, as well as to determine the impact they have on the recovery period and the professional integration of patients. The research was based on data obtained from 52 patients who received treatment in 2015-2019. The results of the study show that the surgical treatment of the trigger finger performed by transverse incision at the level of the distal palmar fold with local anesthesia is associated with a very good result from a functional point of view, a low rate of postoperative complications and favorable aesthetic appearance.

Trigger finger is one of the most common upper extremity problems seen by hand surgeons. Lesions occupying space in the tendon bed can prevent tendon gliding. We describe a unique case of trigger finger in a patient known for a hereditary multiple exostoses disease where an exostosis in the tendon bed constricted the tendon sheath, leading to triggering and locking. Open surgical treatment was performed by removing of the exostosis which relieved the problem. Level of Evidence: Level V, therapeutic study. [ABSTRACT FROM AUTHOR]

The purpose of this study was to test the hypothesis that an improved outcome can be achieved by employing simultaneous steroid injection after percutaneous A1 pulley release. One hundred and twelve digits were randomized to either percutaneous A1 pulley release alone or release of the A1 pulley with a steroid injection. The visual analogue scale score for pain, modified patient global impression of improvement and modified Quinnell grade were assessed at 3 weeks and 3 months after surgery. At 3 weeks, subjective improvement in the group with simultaneous steroid injection was significantly superior. At 3 months, pain score in the patients without a steroid injection was significantly better. No significant differences were found in the modified Quinnell grade. We conclude from this study that the simultaneous steroid injection at the time of surgical release decreases pain and improves subjective outcomes during the early postoperative period after percutaneous trigger finger release.Level of evidence: I [ABSTRACT FROM AUTHOR]

We investigated incidence, clinical features and surgical outcomes of trigger finger accompanied by proximal interphalangeal joint pain. One-hundred and seventy-nine consecutive patients with trigger finger who had A1 pulley release were recruited. Forty-two patients (24%) complained of proximal interphalangeal joint pain at the time of surgery. Symptom duration was investigated, and tenderness at the proximal interphalangeal joint was palpated. Range of motion and pain score of the affected finger were measured pre- and post-operatively. Bone scan was performed to identify joint lesions. A comparison of the results between the proximal interphalangeal joint pain group and the non-proximal interphalangeal joint pain group shows that the proximal interphalangeal joint pain seemed to result from long symptom duration and consequent joint pathology. The proximal interphalangeal joint pain was incompletely resolved after A1 pulley release. Thus, the surgical outcomes might be worse than expected in spite of resolution of painful clicking, especially when there was additional joint tenderness on palpation.Level of evidence: IV [ABSTRACT FROM AUTHOR]

Systematic review Trigger finger (TF) is a common condition in the hand. The primary purpose of this systematic review was to evaluate the current evidence to determine the efficacy of orthotic management of TF. A secondary purpose was to identify the characteristics of the orthotic management. The tertiary purpose of this study was to ascertain if the studies used a patient-reported outcome to assess gains from the patient's perspective. All studies including randomized controlled trials, prospective, and retrospective cohort studies were included in this review due to limited high-level evidence. Four authors demonstrated moderate to large effect sizes ranging from 0.49 to 1.99 for pain reduction after wearing an orthotic device. Two authors demonstrated a change in the stages of stenosing tenosynovitis scale scores showing a clinically important change with a large effect size ranging from 0.97 to 1.63. Seven authors immobilized a single joint of the affected digit using a variety of orthoses. All authors reported similar results regardless of the joint immobilized; therefore for orthotic management of the TF, we recommend a sole joint be immobilized for 6-10 weeks. In assessing TF, most authors focused on body structures and functions including pain and triggering symptoms, 2 authors used a validated functional outcome measure. In the future therapists should use a validated patient report outcome to assess patient function that is sensitive to change in patients with TF. Furthermore, more randomized controlled trials are needed. • Symptom reduction was noted by using an orthosis for 6-10 weeks continually. • Various orthosis may be used, limiting excursion by immobilizing MP, PIP, or DIP. • Use validated patient outcome measures and high level studies for best practice.

Objective: The purpose of this study was to evaluate the efficacy of ultrasonography-guided percutaneous A1 pulley release with the needle knife for trigger finger. Methods: The prospective study included 21 patients (21 fingers) who underwent blind release with the needle knife and 20 patients (20 fingers) who underwent ultrasonography-guided release with the needle knife. The thickness and width of A1 pulley, clinical grade before and after release, complications, and operation time were compared between the groups. Results: The results showed that the ultrasonography-guided group had significantly better grade postoperatively and reached to 100% complete release in one time compared to the blind group (p < 0.05). Moreover, no any complications had been happened in the ultrasonography-guided group. A relatively longer operation time of the ultrasonography-guided group was observed compared to the time of the blind group. Conclusions: The needle knife is a very good tool for release of triggering fingers. Ultrasound provides a direct and precise visualization of the thickness, width and location of A1 pulley lesion. The combined use of ultrasound and the needle knife can achieve the best result for trigger finger. Moreover, the combination changes the traditional opinion and operator-dependent mode that were once widely adopted in the hospital of Chinese Medicine. [ABSTRACT FROM AUTHOR]

The Friends and Family Test, a variant of the Net Promoter Score, was adapted for the National Health Service to evaluate overall patient satisfaction and how likely patients are to recommend an intervention. It ranges from −100 to 100. Positive scores indicate good performance. This study quantifies the scores in 810 patients at a mean of 14 months following four common procedures. The score was 83 for trigger finger release (n = 103), 68 for carpal tunnel decompression (n = 467), 62 for surgery for Dupuytren's disease (n = 224) and 44 for ganglia excision (n = 16). Our study indicates that these procedures are highly valued and are recommended by patients according to the Friends and Family Test. The results of the Friends and Family Test correlated well with postoperative functional improvement and satisfaction. We conclude from this study that a compound score based on the Friends and Family Test is a useful addition to traditional measures of patient satisfaction.Level of evidence: II [ABSTRACT FROM AUTHOR]

Diabetics have a much greater prevalence of trigger finger than nondiabetics and are more likely to have severe symptoms. Diabetic trigger finger may be more accurately described on a spectrum of diabetic hand pathology alongside carpal tunnel syndrome and cheiroarthropathy. Recent publications have called into question the current treatment algorithm for diabetic trigger finger. Although some evidence supports the use of corticosteroid injections, a recent cost analysis reported that immediate surgical release of the A1 pulley in the clinic is the most cost-effective management of diabetic trigger finger. In addition to traditional treatment with injection and open release, percutaneous release with or without simultaneous corticosteroid injection has shown promising results and may have a role in patient care. The appropriate treatment algorithm in terms of efficacy, safety, and cost remains controversial. [ABSTRACT FROM AUTHOR]

Introduction: Trigger finger is one of the most common causes of hand pain in adults. The pathophysiology is unclear but inflammation and age-related degeneration have been suggested. The equiangular spiral is one of the most engaging patterns which perfectly formed flawlessly executed by transitory movement of the digits in the adaptability of the human hand. This study was done to find out the relationship between the Fibonacci ratios of the finger with trigger fingers. Method: Forty-eight patients who had trigger finger and undergone A1 pulley released were being identified and collected. From the hand radiograph, the length of each metacarpal and proximal phalanx was measured manually. The ratio of the metacarpal bony length to the length of the respective proximal phalanx is the Fibonacci ratio of the digit. Results: There was a significant linear relationship found between trigger finger and Fibonacci ratio (p<0.001). Conclusion: Finger Fibonacci ratio significantly determines the smoothness patterns of its tendon movements. [ABSTRACT FROM AUTHOR]

Background and purpose: Evidence suggest high prevalence of trigger finger (TF) in diabetic patients. Corticosteroid injection in the area of tendon sheath thickening is the first-line treatment of choice for TF. However, some studies indicated low efficacy of this method in diabetic patients. This study aimed at investigating the effectiveness of oral corticosteroids in diabetic patients with TF. Materials and methods: In a clinical trial, 50 diabetic patients with trigger finger (n=106 digits) enrolled. The patients were treated with oral prednisolone 5 mg, three times a day for 2 weeks. They were then followed up based on Quinnell grading at 3 and 6 weeks, and 3 months. Data analysis was done in SPSS V17 applying Repeated measures ANOVA. Results: At the end of the three-month follow-up, 84 fingers (79.3%) of patients who took oral prednisolone improved. The reduction of Quinnell grading was significant after medication (p<0.001). Positive correlation was observed between symptoms duration and disease severity at third month (r=0.37, p<0.0001). In addition, there were positive correlations between the number of fingers affected and diabetes mellitus duration (r=0.425, p=0.002), HbA1C (r=0.319, p=0.024), and 2HPP (r=0.29, p=0.041). Conclusion: Current study showed no local side effects of corticosteroids in patients receiving oral prednisolone. Therefore, it could be suggested as an influential treatment for trigger finger in diabetic patients, especially those with less than 6 months onset of symptoms, normal blood glucose control, less severity of the symptoms, and higher number of involved fingers.

Purpose Carpal tunnel syndrome and trigger finger (TF) frequently present concomitantly; some studies suggest that carpal tunnel release (CTR) is a risk factor for the development of ipsilateral TF in the postoperative period. The primary objective of this study was to elucidate the relationship between CTR and the subsequent development of TF. Methods A retrospective study was conducted of 1,386 hands in 1,140 patients who underwent primary CTR at a tertiary referral center from July 2008 to June 2013. After exclusion of cases in which contralateral CTR was performed within the first postoperative year after ipsilateral CTR, conditional logistic regression was performed in 906 hands in 890 patients to determine the association between CTR and TF in the first postoperative year in the operative hand compared with the contralateral hand. Conditional logistic regression and Poisson regression were performed in 1,386 hands in 1,140 patients to examine the association between CTR and TF in the year before surgery compared with the year after surgery. Multivariable regression analysis was used to determine associated risk factors. Results Of 1,386 hands, a new TF was seen in 147 (10.6%) within 1 year before CTR and 81 (5.8%) within 1 year after CTR. The occurrence of postoperative TF was associated with 2.5 times higher odds in the operative hand compared with the contralateral hand in the conditional logistic regression model of 906 cases. However, the incidence of TF was associated with 0.5 times lower odds during the year after CTR compared with the year before CTR in both conditional logistic regression and Poisson regression models of 1,386 cases. Increased body mass index is statistically associated with TF after CTR, but the attributable risk is negligible. Conclusions There is a predisposition for these 2 common hand pathologies to present in the same hand; however, patients can be counseled that CTR does not cause new incidence of TF in the operative hand. Type of study/level of evidence Prognostic IV. [ABSTRACT FROM AUTHOR]

Stenosing flexor tenosynovitis, more commonly known as trigger finger , is one of the most common causes of hand pain and dysfunction. Clinicians must be able to identify the disorder, know the broad range of treatment options, and counsel patients on the treatment best suited for their condition. Awareness of the economic burden each option entails is central to optimizing treatment outcomes and patient satisfaction. [ABSTRACT FROM AUTHOR]

Although 'congenital' or paediatric trigger thumb is commonly seen in the paediatric age group, adult presentation is very rare. However it is crucial to acknowledge the occurrence of unusual manifestations of paediatric trigger thumbs, since paediatric trigger thumbs are considered a separate disease entity compared to the commonly seen stenosing tenosynovitis in adults. We report a case of a 18-year-old young lady presenting with atraumatic locked trigger thumb, which was successfully treated surgically with intra-operative finding confirming abnormally thickened flexor pollicis longus tendon signifying a paediatric trigger thumb pathology. Adult and paediatric trigger thumbs have different aetiology, with thickened A1 pulley and tendon sheath being the culprit in adults, whereas in paediatric thumbs thickened tendon nodules (Notta's node) are usually the causes of triggering. This uncommon presentation in this case report is atypical in the age group presentation of paediatric trigger thumb, and should be distinguished from the usual trigger thumb pathology in adults. Although a transient period of extension lag in the early post-operative period may be evident, it can still be successfully treated with surgical release. • It is important to recognize atypical presentation of paediatric trigger thumb even in the adult age group. • The underlying pathology of paediatric trigger thumb is different from adult trigger thumb. • Surgical release of A1 pulley is still an effective treatment despite the long delay.

The purpose of the study was to determine if the patient-reported outcomes measurement information system (PROMIS) is sufficiently sensitive to detect improvement after 2 common treatments of trigger finger: corticosteroid injection or A1 pulley release. This retrospective cohort study included 72 patients in the injection group and 51 in the A1 pulley release group. PROMIS physical function (PF), pain interference (PI), and upper extremity (UE) scores were collected at baseline and 6 weeks after injection for the injection group and at baseline, and 1 week, 6 weeks, and 3 months after surgery for A1 pulley release patients. Descriptive statistics and paired t tests were used to compare PROMIS scores within each cohort. Standardized response means (SRMs) were calculated for each PROMIS domain to gauge instrument responsiveness. Average age was 62 years, 65% were female patients, and 86% were White for the steroid injection cohort, compared to 60 years, 71%, and 88%, respectively, for the A1 pulley release cohort. For the steroid injection group, mean PROMIS PI scores (−4.0 points; SRM = −0.6) and PROMIS UE scores (+3.3 points; SRM = 0.5) improved significantly at 6 weeks after injection compared to baseline. Meanwhile, A1 pulley release patients improved significantly in mean PI scores (−3.7 points; SRM = −0.5) and in UE scores (+4.9 points; SRM = 0.7) at 3 months after surgery compared to baseline. Clinical improvements after trigger digit treatments are reflected in improved PROMIS PI and UE scores that reach previously accepted minimum clinically important difference values for hand patients. PROMIS PI and UE also are more responsive than PROMIS PF in capturing improvement for trigger digit treatments. As health care payers continue to emphasize patient-reported outcomes to determine treatment value and set reimbursement rates, this study helps establish that clinical improvement after trigger digit treatments are reflected in PROMIS PI and UE domains by reaching previously established minimum clinically important difference values for hand patients.
