[The diabetic hand - a forgotten complication]. / Den diabetiska handen ­ ett i dag bortglömt syndrom.

The term ¼the diabetic hand« traditionally denotes complications affecting the hand in individuals with diabetes mellitus, such as restricted finger movement, numbness, and pain. Trigger finger, Dupuytren's disease, carpal tunnel syndrome, ulnar nerve entrapment, and osteoarthritis of the first carpometacarpal joint are all conditions that are more prevalent among individuals with both type 1 and type 2 diabetes. This overview aims to shed light on a somewhat neglected area in diabetes complications, i.e. the diabetic hand, to increase the knowledge among physicians and surgeons as well as nurses, physiotherapists, and occupational therapists treating patients with diabetes.

Collagenase Injection versus Limited Fasciectomy for Dupuytren's Contracture.

BACKGROUND: Treatments for Dupuytren's contracture include limited fasciectomy and collagenase injection. Comparisons of the effectiveness of these treatments have been limited. METHODS: We performed an unblinded, multicenter, pragmatic, two-group, randomized, controlled noninferiority trial comparing collagenase injection with limited fasciectomy in persons with moderate Dupuytren's contracture. The primary outcome was the score on the Patient Evaluation Measure-Hand Health Profile (PEM), a questionnaire for assessing hand health as reported by the patient, at 1 year after treatment. Scores on the PEM range from 0 to 100, with higher scores indicating worse outcomes. The prespecified noninferiority margin was 6 points. RESULTS: A total of 672 persons (336 per group) were assigned to receive collagenase injection or to undergo limited fasciectomy. The primary analysis included 599 persons: 314 in the collagenase group and 285 in the limited-fasciectomy group. The mean score on the PEM at 1 year was 17.8 among the 284 patients with available data in the collagenase group and 11.9 among the 250 patients with available data in the limited-fasciectomy group (estimated difference, 5.9 points; 95% confidence interval [CI], 3.1 to 8.8; one-sided P = 0.49 for noninferiority). Among the patients with available data (229 patients in the collagenase group and 197 patients in the limited-fasciectomy group), the estimated difference in the mean score on the PEM at 2 years was 7.2 points (95% CI, 4.2 to 10.9). Moderate or severe complications of treatment occurred in 1.8% of the patients in the collagenase group and in 5.1% of those in the limited-fasciectomy group; recurrent contracture resulted in reintervention in 14.6% and 3.4%, respectively. CONCLUSIONS: Collagenase injection was not noninferior to limited fasciectomy with respect to the score on the PEM at 1 year after treatment.

EN: Medico-legal evaluation of a claim for Dupuytren's disease treatment: indication for surgery based on best evidence.

Background: Dupuytren's disease (DD) is a chronic and progressive fibroproliferative disease consisting of the progressive pathological fibrosis of the palmar fascia leading to permanent flexion and deficit of extension, with marked deformity and severe disability. Among treatment options, conservative and infiltrative therapies, physiotherapy, or surgery, with less invasive surgical options, are reported. The therapeutic planning, shared with the patient, must consider the severity of the disease, surgical risks, the functional, aesthetic, and occupational consequences, and the risk of recurrence. Case report: We describe a complicated clinical case that led her to a claim for compensation under presumed medical professional liability profiles. A female patient, 32-years-old, suffering from early symptomatic DD in the left non-dominant hand, underwent to palmar fasciotomy complicated by severe paraesthesia. In the re-surgery, vascular and nerve injury was found, leading to permanent disabling sequelae. Discussion: The early stage of DD, although symptomatic, without previous medical or infiltrative therapy, in a young subject with insulin-dependent diabetes and a high risk of recurrence contraindicated the surgical approach, especially palmar fasciotomy, according to the best evidence. The vascular-nervous lesion in the hand palm indicated a censurable surgical execution technique. The technical consultation ascertained the causal relationship between impairments and surgical malpractice, followed by compensation. Conclusion: The analysis of this case highlights the value of informed clinical practice to provide optimal care and mitigate the risks associated with the management of DD. The choice of possible treatment options must be tailored to the patient in accordance with the best evidence.

Dupuytren's disease and occupational mechanical exposures: a systematic review and meta-analysis.

The risk of developing Dupuytren's disease among workers exposed to occupational mechanical exposures has been reported in few systematic reviews, mainly related to vibration. Expanding the investigation to all occupational mechanical exposures is essential for advancing scientific knowledge, health policies and improving workplace safety. The aim of this systematic review and meta-analysis was to study the association between occupational mechanical exposures and Dupuytren's disease.We conducted a systematic review and meta-analysis using guidelines stated by PRISMA. The systematic literature search was performed in Medline, EMBASE, CINAHL, Cochrane Library and Web of Science databases in April 2023. Inclusion criteria were conducted using the PECOS. Two independent authors conducted the literature screening, data extraction and risk of bias assessment. In the meta-analyses, data was pooled using random-effects models and stratified by the risk of bias and study design. The level of evidence was evaluated using GRADE.The literature search identified 563 unique articles and 15 were deemed eligible for inclusion, categorised into hand-transmitted vibration, lifting/carrying loads and combined mechanical exposures. Exposure to hand-transmitted vibration showed an OR of 2.0 (95% CI 1.5 to 2.7, I2=64%), lifting/carrying loads had an OR of 1.5 (95% CI 1.1 to 2.0, I2=77%) and combined mechanical exposures had an OR of 2.1 (95% CI 1.4 to 3.1, I2=94%). When grading the level of evidence, we found moderate evidence for hand-transmitted vibration, while low evidence was found for lifting/carrying loads and combined mechanical exposures.We found an association between hand-transmitted vibration, lifting/carrying loads and combined mechanical exposures. The level of evidence was considered moderate for hand-transmitted vibration and low for lifting/carrying loads and combined mechanical exposures.

[Dupuytren's disease : Epidemiology, diagnosis, treatment, outcome]. / Morbus Dupuytren : Epidemiologie, Diagnose, Therapie, Outcome.

Dupuytren's contracture is a fibroproliferative systemic disease that cannot be stopped by medication. The overall prevalence is 7-8%. Men are affected 3-4 times more frequently. The cause of the disease is not known. A genetic disposition and thus familial clustering are being discussed. Risk factors for the development of a Dupuytren's contracture are work-related stress (microtrauma), nicotine and alcohol consumption, epilepsy and diabetes mellitus as well as advanced age. The prognosis is poor in cases with a positive family history, bilateral involvement, age < 50 years and male gender. Several treatment options are available. Conservative therapy has no lasting benefit. Minimally invasive procedures include partial needle aponeurectomy or the injection of collagenase. Surgical procedures range from partial aponeurectomy to dermatoaponeurectomy. The recurrence risk of the gold standard treatment of surgery (partial aponeurectomy) is 20.9%.

Limited fasciectomy with versus without autologous adipose tissue grafting for treatment of Dupuytren's contracture (REMEDY): study protocol for a multicentre randomised controlled trial.

BACKGROUND: Dupuytren's contracture is a hereditary disorder which causes progressive fibrosis of the palmar aponeurosis of the hand, resulting in digital flexion contractures of the affected rays. Limited fasciectomy is a standard surgical treatment for Dupuytren's, and the one with the lowest recurrence rate; however, the recurrence is still relatively high (2-39%). Adipose-derived stem cells have been shown to inhibit Dupuytren's myofibroblasts proliferation and contractility in vitro, as well as to improve scar quality and skin regeneration in different types of surgeries. Autologous adipose tissue grafting has already been investigated as an adjuvant treatment to percutaneous needle fasciotomy for Dupuytren's contracture with good results, but it was only recently associated with limited fasciectomy. The purpose of REMEDY trial is to investigate if limited fasciectomy with autologous adipose tissue grafting would decrease recurrence compared to limited fasciectomy alone. METHODS: The REMEDY trial is a multi-centre open-label randomised controlled trial (RCT) with 1:1 allocation ratio. Participants (n = 150) will be randomised into two groups, limited fasciectomy with autologous adipose tissue grafting versus limited fasciectomy alone. The primary outcome is the recurrence of Dupuytren's contracture on any of the treated rays at 2 years postoperatively. The secondary outcomes are recurrence at 3 and 5 years, scar quality, complications, occurrence of algodystrophy (complex regional pain syndrome), patient-reported hand function, and hypodermal adipose tissue loss at 1 year postoperatively in a small subset of patients. DISCUSSION: The REMEDY trial is one of the first studies investigating limited fasciectomy associated with autologous adipose tissue grafting for Dupuytren's contracture, and, to our knowledge, the first one investigating long-term outcomes of this treatment. It will provide insight into possible benefits of combining adipose tissue grafting with limited fasciectomy, such as lower recurrence rate and improvement of scar quality.

Dupuytren's Contracture: Approach to Treatment and Counseling Patients in 2024.

Dupuytren disease is a progressive disease process that causes debilitating flexion contractures of the metacarpophalangeal and proximal interphalangeal joints. There are multiple interventions to choose from, ranging from minimally invasive techniques with little downtime to open surgical excision with a lengthy postoperative rehabilitation. Our understanding of the disease process continues to evolve. Depending on the extent of flexion contracture, needle aponeurotomy and collagenase injection have satisfactory results with moderate long-term efficacy. Surgical palmar fasciectomy continues to be the mainstay treatment of extensive contractures, with durable results.

[Treatment of Dupuytren's disease; limited fasciectomy versus percutaneous needle fasciotomy]. / Behandeling van de ziekte van Dupuytren.

OBJECTIVE: We estimated retreatment risk following limited fasciectomy (LF) or percutaneous needle fasciotomy (PNF) for Dupuytren's disease. DESIGN: Prospective cohort study. METHOD: Using frailty models, we estimated retreatment risk within 1,3,5,10 and 20 years. RESULTS: LF showed a 10-year retreatment risk of 8% (95%CI: 3-13%) for men and 4% (95%CI: 1-8%) for women without an affected first-degree relative, initially treated at 60 years. PNF showed higher risks at 69% (95%CI: 52-86%) and 46% (95%CI: 16-77%). Younger age at initial treatment increased retreatment risk, sex and first-degree relative had no influence. CONCLUSION: LF gives a longer-lasting treatment effect than PNF.

Adjuvant Treatment with Celecoxib after Collagenase Injection for Dupuytren Contracture: A Double-Blind Randomised Controlled Trial.

Background: In patients with a high recurrence risk after treatment for Dupuytren contracture (DC) by Collagenase Clostridium histolyticum (CCH), adjuvant medical therapy may improve the outcome. Non-steroidal anti-inflammatory drugs have been used in the treatment of similar fibroproliferative processes. The aim of this study was to investigate if adjuvant anti-inflammatory medication could improve the outcome of CCH treatment for DC. Methods: In a prospective double blinded randomised trial, the effect of adjuvant peroral celecoxib on the outcome of DC treated with CCH was investigated in 32 patients with a high fibrosis diathesis. Primary outcome was the increase in Total Passive Extension Deficit (TPED)/ray. Secondary outcomes were the TPED of the individual finger joints, Tubiana index, Disability of Arm, Shoulder and Hand score (DASH) and visual analogue scale (VAS) for pain and satisfaction. Results: A significantly greater improvement in the celecoxib group for TPED and metacarpophalangeal contracture was found. For the proximal interphalangeal joint, the effect was much less pronounced. The VAS for pain and satisfaction were better at 6 and 12 weeks in the celecoxib group. The other outcome parameters did not significantly differ between both groups. Conclusions: Adjuvant peroral administration of celecoxib might improve the gain in TPED after treatment with CCH in patients with DC and a high fibrosis diathesis, with a beneficial effect up to 24 months. Level of Evidence: Level II (Therapeutic).

Challenges and innovations in the surgical treatment of advanced Dupuytren disease by percutaneous needle fasciotomy: indications, limitations, and medico-legal implications.

BACKGROUND: Dupuytren disease, a chronic thickening and retraction of the palmar aponeurosis of the hands, may result in permanent and progressive flexion of one or more fingers. Percutaneous needle fasciotomy is a simple method that uses a hypodermic needle usually performed under local anaesthesia. The study aim was to report the postoperative results and complications using a percutaneous approach to treat Dupuytren contracture in a consecutive series of patients with advanced Dupuytren disease, also considering the relevant medico-legal implications. METHODS: Retrospective multicentre study of all patients with Tubiana stage 3-4 Dupuytren contracture treated with percutaneous needle aponeurotomy, with no ultrasound assistance, from 2012 to 2022. Patient demographics, disease severity, treatment-related complications, and the incidence of recurrence were identified. An overview of therapeutic treatment options has accounted for 52 relevant sources spanning the 2007-2023 time period. RESULTS: Overall, 41.7% (N = 200) of patients were females, the mean age was 72 years (60-89), the right hand was treated in 54.2% (N = 260) of patients. The little finger was involved in 50% of the patients. The 12 months mean PED was 9°, the mean quickDASH was 8, the mean URAM 6. Minor complications were reported in 18.7% (N = 90) of patients, typically skin lacerations (83.3%) with no clinical sequelae, and no major complications were reported. Recurrence occurred in 30% (N = 144) of patients. CONCLUSIONS: Percutaneous needle fasciotomy is safe and reliable even in patients with advanced Dupuytren disease, resulting in predictably acceptable outcome with low risk of complications.

Alterations in the Structure, Composition, and Organization of Galactosaminoglycan-Containing Proteoglycans and Collagen Correspond to the Progressive Stages of Dupuytren's Disease.

Dupuytren's disease (DD) is a prevalent fibroproliferative disorder of the hand, shaped by genetic, epigenetic, and environmental influences. The extracellular matrix (ECM) is a complex assembly of diverse macromolecules. Alterations in the ECM's content, structure and organization can impact both normal physiological functions and pathological conditions. This study explored the content and organization of glycosaminoglycans, proteoglycans, and collagen in the ECM of patients at various stages of DD, assessing their potential as prognostic indicators. This research reveals, for the first time, relevant changes in the complexity of chondroitin/dermatan sulfate structures, specifically an increase of disaccharides containing iduronic acid residues covalently linked to either N-acetylgalactosamine 6-O-sulfated or N-acetylgalactosamine 4-O-sulfated, correlating with the disease's severity. Additionally, we noted an increase in versican expression, a high molecular weight proteoglycan, across stages I to IV, while decorin, a small leucine-rich proteoglycan, significantly diminishes as DD progresses, both confirmed by mRNA analysis and protein detection via confocal microscopy. Coherent anti-Stokes Raman scattering (CARS) microscopy further demonstrated that collagen fibril architecture in DD varies importantly with disease stages. Moreover, the urinary excretion of both hyaluronic and sulfated glycosaminoglycans markedly decreased among DD patients.Our findings indicate that specific proteoglycans with galactosaminoglycan chains and collagen arrangements could serve as biomarkers for DD progression. The reduction in glycosaminoglycan excretion suggests a systemic manifestation of the disease.

Biochemical and Histological Differences between Longitudinal and Vertical Fibres of Dupuytren's Palmar Aponeurosis and Innovative Clinical Implications.

Dupuytren's disease, a chronic and progressive fibroproliferative lesion of the hand, which affects the palmar fascia, has a recurrence rate after selective aponeurotomy of 20-40% at 5 years. This study focused, for the first time, on the microanatomical and histopathological characteristics of the longitudinal and vertical fibres (usually spared during surgery) in the aponeurosis with Dupuytren's disease, in different stages of the Tubiana's classification. Twelve human samples were collected and analysed by immunostaining, Total Collagen Assay, ELISA Immunoassay, and immunoblotting for the Von Willebrand factor, α-Sma, D2-40, CD-68, Total Collagen, Collagen-I and III, IL1ß, TNF-α to analyse the blood and lymphatic vascularization, the amount and distribution of collagen, and the inflammation. The results show a progressive increase in the arterial vascularization in the vertical fibres (from 8.8/mm2 in the early stage to 21.4/mm2 in stage 3/4), and a parallel progressive decrease in the lymphatic drainage (from 6.2/mm2 to 2.8/mm2), correlated with a local inflammatory context (increase in IL-1ß and TNF-α until the stage 2) in both the longitudinal and vertical fibres. The acute inflammation after stage 2 decreased, in favour of a fibrotic action, with the clear synthesis of new collagen (up to ~83 µg/mg), especially Collagen-I. These results clearly demonstrate the involvement of the septa of Legueu and Juvara in the disease pathology and the modifications with the disease's progression. A greater understanding of the pathology becomes fundamental for staging and the adequate therapeutic timing, to obtain the best morpho-functional result and the lowest risk of complications.

Risk of hand and forearm conditions due to vibrating hand-held tools exposure: a retrospective cohort study from Sweden.

OBJECTIVES: The occurrence of hand and forearm disorders related to vibration exposure, adjusted for relevant background factors, is scarcely reported. We analysed the prevalence of such conditions in a large population cohort, stratified by sex, and associations with exposure to vibrating hand-held tools. DESIGN: This is a retrospective cohort study. SETTING: Individuals in the Malmö Diet and Cancer Study cohort (MDCS; inclusion 1991-1996; followed until 2018) were asked, 'does your work involve working with vibrating hand-held tools?' (response: 'not at all', 'some' and 'much'). Data were cross-linked with national registers to identify treatment for carpal tunnel syndrome (CTS), ulnar nerve entrapment (UNE), Dupuytren's disease, trigger finger or first carpometacarpal joint (CMC-1) osteoarthritis (OA). Cox regression models, unadjusted and adjusted (age, sex, prevalent diabetes, smoking, hypertension and alcohol consumption), were performed to analyse the effects of reported vibration exposure. PARTICIPANTS: Individuals in the MDCS who had answered the questionnaire on vibration exposure (14 342 out of the originally 30 446 individuals in MDCS) were included in the study. RESULTS: In total, 12 220/14 342 individuals (76%) reported 'no' exposure, 1392/14 342 (9%) 'some' and 730/14 342 (5%) 'much' exposure to vibrating hand-held tools. In men, 'much' exposure was independently associated with CTS (HR 1.71 (95% CI 1.11 to 2.62)) and UNE (HR 2.42 (95% CI 1.15 to 5.07)). 'Some' exposure was independently associated with UNE in men (HR 2.10 (95% CI 1.12 to 3.95)). 'Much' exposure was independently associated with trigger finger in women (HR 2.73 (95% CI 1.49 to 4.99)). We found no effect of vibration exposure on Dupuytren's disease or CMC-1 OA. 'Much' vibration exposure predicted any hand and forearm diagnosis in men (HR 1.44 (95% CI 1.08 to 1.80)), but not in women. CONCLUSIONS: Vibration exposure by hand-held tools increases the risk of developing CTS and UNE and any common hand and forearm conditions in men, whereas women only risk trigger finger and CMC-1 OA. Adjustment for relevant confounders in vibration exposure is crucial.

Inflammatory Markers Involved in the Pathogenesis of Dupuytren's Contracture.

Dupuytren's disease is a common fibroproliferative disease that can result in debilitating hand deformities. Partial correction and return of deformity are common with surgical or clinical treatments at present. While current treatments are limited to local procedures for relatively late effects of the disease, the pathophysiology of this connective tissue disorder is associated with both local and systemic processes (e.g., fibrosis, inflammation). Hence, a better understanding of the systemic circulation of Dupuytren related cytokines and growth factors may provide important insights into disease progression. In addition, systemic biomarker analysis could yield new concepts for treatments of Dupuytren that attenuate circulatory factors (e.g., anti-inflammatory agents, neutralizing antibodies). Progress in the development of any disease modifying biologic treatment for Dupuytren has been hampered by the lack of clinically useful biomarkers. The characterization of nonsurgical Dupuytren biomarkers will permit disease staging from diagnostic and prognostic perspectives, as well as allows evaluation of biologic responses to treatment. Identification of such markers may transcend their use in Dupuytren treatment, because fibrotic biological processes fundamental to Dupuytren are relevant to fibrosis in many other connective tissues and organs with collagen-based tissue compartments. There is a wide range of potential Dupuytren biomarker categories that could be informative, including disease determinants linked to genetics, collagen metabolism, as well as immunity and inflammation (e.g., cytokines, chemokines). This narrative review provides a broad overview of previous studies and emphasizes the importance of inflammatory mediators as candidate circulating biomarkers for monitoring Dupuytren's disease.

Needle fasciotomy versus limited fasciectomy for the treatment of Dupuytren's contractures of the fingers (Hand-2): study protocol for a randomised controlled trial.

BACKGROUND: Dupuytren's contractures (DC) are fibrous cords under the skin of the hand that cause one or more fingers to curl gradually and irreversibly towards the palm. These contractures are usually painless but can cause a loss of hand function. Two treatments for Dupuytren's contractures are widely used within the National Health Service (NHS) in the UK: removal of the contractures via surgery (limited fasciectomy) and division of the contractures via a needle inserted through the skin (needle fasciotomy). This study aims to establish the clinical and cost-effectiveness of needle fasciotomy (NF) versus limited fasciectomy (LF) for the treatment of DC in the NHS, in terms of patient-reported hand function and resource utilisation. METHODS/DESIGN: Hand-2 is a national multi-centre, two-arm, parallel-group randomised, non-inferiority trial. Patients will be eligible to join the trial if they are aged 18 years or older, have at least one previously untreated finger with a well-defined Dupuytren's contracture of 30° or greater that causes functional problems and is suitable for treatment with either LF or NF. Patients with a contracture of the distal interphalangeal joint only are ineligible. Eligible consenting patients will be randomised 1:1 to receive either NF or LF and will be followed up for 24 months post-treatment. A QuinteT Recruitment Intervention will be used to optimise recruitment. The primary outcome measure is the participant-reported assessment of hand function, assessed by the Hand Health Profile of the Patient Evaluation Measure (PEM) questionnaire at 12 months post-treatment. Secondary outcomes include other patient-reported measures, loss of finger movement, and cost-effectiveness, reported over the 24-month post-treatment. Embedded qualitative research will explore patient experiences and acceptability of treatment at 2 years post-surgery. DISCUSSION: This study will determine whether treatment with needle fasciotomy is non-inferior to limited fasciectomy in terms of patient-reported hand function at 12 months post-treatment. TRIAL REGISTRATION: International Standard Registered Clinical/soCial sTudy ISRCTN12525655. Registered on 18th September 2020.

Long-term results of the Malingue technique in the surgical treatment of Dupuytren's disease.

OBJECTIVES: The choice of surgical technique for aponeurectomy in Dupuytren's disease is controversial due to varying outcomes and complication rates. The Malingue plasty has shown mathematical and mechanical advantages, but long-term efficacy and results compared to other techniques have never been reported. This study aimed to evaluate the long-term functional, esthetic and recurrence outcomes of Malingue plasty in Dupuytren's disease. MATERIAL AND METHODS: The study included patients who underwent aponeurectomy with Malingue plasty performed by a highly experienced surgeon between January 2014 and December 2016, with a minimum follow-up of 5 years. Preoperative records were analyzed. At follow-up, extension lag was analyzed in each joint (metacarpophalangeal, proximal interphalangeal and distal interphalangeal) in each operated finger, as well as signs of recurrence or extension of the disease. Function and esthetics were assessed using the QuickDASH (Disabilities of the Arm, Shoulder and Hand) questionnaire and the Michigan Hand Outcomes Questionnaire. RESULTS: Out of 107 eligible patients, 55 were included in the study after exclusions and loss to follow-up. Three patients required revision surgery for recurrence during follow-up. All preoperative deformities of the proximal interphalangeal and metacarpophalangeal joints were corrected postoperatively, and no intraoperative or postoperative complications occurred. Mean extension deficit at follow-up was 18.1 °. Only the little finger showed significant loss of correction (p = 0.02). Mean QuickDASH score was 13.2 and the overall Michigan Hand Outcomes Questionnaire score was 91.8%. Recurrence affected 50% of patients according to the Leclercq criteria and 27.5% according to the Felici criteria. CONCLUSION: Although Malingue plasty did not improve the recurrence rate in Dupuytren's disease compared with other techniques, its advantages in terms of functional improvement and complications make it an interesting surgical option.

The Effects of Shock Wave Therapy on the Symptoms and Function of Individuals With Dupuytren Disease: A Systematic Review.

OBJECTIVE: To systematically evaluate the effects of extracorporeal shockwave therapy (ESWT) on pain, clinical and functional outcomes, and satisfaction of patients with Dupuytren disease. DATA SOURCES: A thorough search for all the study types published in English was conducted in PubMed, Scopus, Web of Science, and Embase from inception to August 31, 2022. STUDY SELECTION: Title and abstract and then full-text screening against eligibility criteria was performed independently by 2 reviewers, and a third reviewer achieved consensus. DATA EXTRACTION: Reviewers identified 26 studies, of which 6 were included in the analysis (145 cases). The methodological quality was assessed using the National Heart, Lung, and Blood Institute and the Joanna Briggs Institute checklists. The certainty of evidence was evaluated using the Grading of Recommendation Assessment, Development, and Evaluation. DATA SYNTHESIS: Assessments represented a remarkable improvement in the pain and function through the measurements including the visual analog scale, the Disabilities of Arm Shoulder and Hand Questionnaire, the Michigan Hand Outcome Questionnaire, and Mayo Wrist Score. Patients' satisfaction was also favorable using the Roles and Maudsley score. The hand grip strength improvement was noted in one study measured via a Jamar dynamometer. In addition, the ultrasonographic assessment of the nodules revealed a decrease in the size of the nodules in a patient with multiple bilateral nodules after the treatment. The quality of the included studies was good for all studies except for one that was fair. The certainty of evidence was moderate for pain and function and was low for patients' satisfaction and ultrasonographic findings. CONCLUSIONS: ESWT can lead to significant pain improvement, functional rehabilitation, and patient satisfaction with no adverse effect in the management of Dupuytren disease. Pain may return over time, but not to that severity before the intervention. ESWT-related characteristics and the need for continuation of treatment remain to be fully elucidated in future large clinical trials.

A 10-Year Review of Collagenase Versus Fasciectomy in the Treatment of Dupuytren Contracture.

BACKGROUND: Dupuytren disease (DD) is one of the most common disorders of the hand, affecting 5.7% to 11.7% of the global population. This study seeks to evaluate the 10-year efficacy of the 2 most prominent treatment modalities for DD in Veterans Affairs hospitals, injectable collagenase Clostridium histolyticum versus open fasciectomy. METHODS: A retrospective review was conducted of all electronic medical records of patients who underwent open fasciectomy or collagenase injection to treat their persistent Dupuytren contracture between April 2011 and April 2021. All procedures were performed by 1 of 5 senior surgeons at the same Veterans Affairs Hospital. RESULTS: A total of 232 patients were treated for DD, with 247 collagenase injections and 44 open fasciectomies performed in this sample. Collagenase patients were, on average, 6.51 years after intervention at the time of review. Open fasciectomy patients were, on average, 4.56 years after operation at the time of review. Collagenase decreased contractures, on average, by 29.40 degrees, whereas open fasciectomy decreased contractures, on average, by 38.59 degrees. Of the contractures that were initially classified as resolved, 50 of 155 (32.2%) treated with collagenase and 6 of 56 (10.7%) treated with open fasciectomy recurred. The use of open fasciectomy compared with collagenase injections to treat contracture was associated with a 74.2% decrease in the likelihood of recurrence. CONCLUSIONS: This study found that treatment of DD with collagenase injection is associated with a significantly lower degree of deformity correction, lower rate of resolution, and increased rate of recurrence when compared with open fasciectomy.

Identifying non-genetic factors associated with trigger finger.

BACKGROUND: The non-genetic factors predisposing to trigger finger (TF) have mostly been characterised in small studies from individual institutions. Here, we aimed to provide a more complete picture of TF and its associations. METHODOLOGY: This case-control study used cross-sectional data from the UK Biobank population-based cohort to identify and determine the strength of associations of phenotypic variables with TF. We performed multivariable logistic regression of a multitude of phenotypic factors associated with TF. RESULTS: We identified 2250 individuals with medical and surgical diagnostic codes for TF, and 398,495 controls. TF was found to be significantly associated with age (OR 1.04, 95% CI 1.03-1.04, P < 2.23×10-308), female sex (OR 1.22, 95% CI 1.08-1.39, P = 2.35×10-3), body mass index (OR 1.10, 95% CI 1.04-1.16, P = 5.52×10-4), carpal tunnel syndrome (OR 9.59, 95% CI 8.68-10.59, P < 2.23×10-308), Dupuytren's disease (OR 4.89, 95% CI 4.06-5.89, P < 2.23×10-308), diabetes mellitus without complications (OR 1.35, 95% CI 1.15-1.58, P = 2.03×10-4) and with complications (OR 2.46, 95% CI 1.90-3.17, P = 4.98×10-12), HbA1c (OR 1.01, 95% CI 1.01-1.02, P = 8.99×10-9), hypothyroidism (OR 1.24, 95% CI 1.07-1.43, P = 4.75×10-3) and rheumatoid arthritis (OR 1.33, 95% CI 1.06-1.68, P = 0.014). CONCLUSION: Our results provide evidence supporting the well-known risk factors such as diabetes mellitus, carpal tunnel syndrome, age and female sex. Furthermore, we can confirm putative associations such as hypothyroidism, obesity and rheumatoid arthritis, while providing evidence against others such as hypertension and hyperlipidaemia. A novel finding arising from this study is the strong association with Dupuytren's disease. Our study design allowed us to identify these associations as being independent from carpal tunnel syndrome, thereby indicating a shared pathophysiology between this disease and TF.

A quality and readability comparison of artificial intelligence and popular health website education materials for common hand surgery procedures.

INTRODUCTION: ChatGPT and its application in producing patient education materials for orthopedic hand disorders has not been extensively studied. This study evaluated the quality and readability of educational information pertaining to common hand surgeries from patient education websites and information produced by ChatGPT. METHODS: Patient education information for four hand surgeries (carpal tunnel release, trigger finger release, Dupuytren's contracture, and ganglion cyst surgery) was extracted from ChatGPT (at a scientific and fourth-grade reading level), WebMD, and Mayo Clinic. In a blinded and randomized fashion, five fellowship-trained orthopaedic hand surgeons evaluated the quality of information using a modified DISCERN criteria. Readability and reading grade level were assessed using Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) equations. RESULTS: The Mayo Clinic website scored higher in terms of quality for carpal tunnel release information (p = 0.004). WebMD scored higher for Dupuytren's contracture release (p < 0.001), ganglion cyst surgery (p = 0.003), and overall quality (p < 0.001). ChatGPT - 4th Grade Reading Level, ChatGPT - Scientific Reading Level, WebMD, and Mayo Clinic written materials on average exceeded recommended reading grade levels (4th-6th grade) by at least four grade levels (10th, 14th, 13th, and 11th grade, respectively). CONCLUSIONS: ChatGPT provides inferior education materials compared to patient-friendly websites. When prompted to provide more easily read materials, ChatGPT generates less robust information compared to patient-friendly websites and does not adequately simplify the educational information. ChatGPT has potential to improve the quality and readability of patient education materials but currently, patient-friendly websites provide superior quality at similar reading comprehension levels.
