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.

Diabetic cheiroarthropathy in uncontrolled type 2 diabetes with positive anti-nuclear antibodies: a case report from Sudan.

Background: Diabetic cheiroarthropathy, also known as limited joint mobility, is one of the long-standing complications of type 2 diabetes mellitus (DM). It affects 8-50% of patients with type 1 diabetes and is also seen in type 2 diabetic patients. Consequently, it can mimic many rheumatological diseases and is often underdiagnosed. The authors present a case of a long-standing poorly controlled diabetes with diabetic cheiroarthropathy and diabetic neuropathy, along with positive ANA in the absence of any correlated autoimmune or rheumatological diseases. Case presentation: A 52-year-old female patient with poorly controlled diabetes (her last HbA1c reading was 9.5%) presented to the Rheumatology clinic with flexion deformities of the fingers. The patient has impaired vibration, two-point discrimination, and pinprick sensation in gloves and stock distribution, indicating peripheral neuropathy, entrapment neuropathy in the forms of bilateral carpal tunnel syndrome, and the diagnosis of diabetic cheiroarthropathy was made. Additionally, she has a positive prayer sign and a tabletop sign. Despite the absence of symptoms and signs of autoimmune disorders, this patient has positive anti-nuclear antibodies global (ANA positive by indirect immuno-fluorescence (IIF) 1\320 nucleolar pattern) with a negative: ANA profile, rheumatoid factor (RF) and anticyclic citrullinated peptide antibody (ACPA). Conclusion: Regular and careful hand examination should be part of clinical assessment for diabetic patients as it could be a very simple and useful screening tool for diabetic cheiroarthropathy. Physicians can use this condition as a mirror for microvascular complications of diabetes. This allows for early detection and appropriate interventions to prevent further progression of diabetes-related complications. It is also essential to consider the presence of positive ANA in diabetic cheiroarthropathy despite the absence of any rheumatological and autoimmune diseases.

Safety and Efficacy of In-Office Hand Procedures.

Background: The primary concerns with operating on patients in the office setting are insufficient sterility and lack of appropriate resources in case of excessive bleeding or other surgical complications. This study serves to investigate these concerns and determine whether in-office hand surgeries are safe and clinically effective. Methods: A retrospective review of patients who underwent minor hand operations in the office setting between December 2020 and December 2021 was performed. The surgical procedures included in this analysis are needle aponeurotomy, trigger finger release, foreign body removal, mass removal, and reduction in a finger fracture with or without percutaneous pinning. All fractures, which primarily included metacarpal and phalangeal fractures, were subsequently splinted. Sterility and hemostatic support were achieved via the Wide-Awake Local Anesthesia No Tourniquet (WALANT) method. Major complications were defined as infection, major bleeding, and neurological deficits. Minor complications were defined as prolonged pain, prolonged inflammation, residual symptoms, and recurrence of symptoms within 1 month. Results: Five patients (3.8%) returned to the office for pain, inflammation, or stiffness of the affected finger, with two of the five returning with symptoms associated with osteoarthritis or pseudogout flare-ups. Five additional patients returned due to residual symptoms or recurrence of the primary complaint within 1 month of surgery. No patients experienced exogenous infection. Conclusion: The absence of major complications and high success rate for minor hand procedures shows the high degree of safety and efficacy that can be achieved via the in-office setting for select procedures. While proper patient selection is key, our result shows the in-office procedure room setting can offer the necessary elements of sterility and hemostatic support for several common hand surgeries.

Collagenase Clostridium Histolyticum for the Treatment of Dupuytren Disease: A Delphi-Based Consensus Study.

Purpose: The aim of this study was to establish the consensus recommendations among hand surgeons who were experts in the use of collagenase clostridium histolyticum (CCH) on the appropriate treatment of Dupuytren disease in well-defined patient populations with varying degrees of disease severity and functional impairment. Methods: A three-round, blinded, modified Delphi process examined panelists' approaches to CCH treatment of metacarpophalangeal (MP) or proximal interphalangeal (PIP) joint contractures involving one or two fingers with varying degrees of severity. Clinical scenarios related to poor-quality skin, postfasciectomy scarring, boutonnière deformity, closed capsulotomy, and blood thinner use were also presented for panelist consideration. Panelists provided responses to clinical scenarios using a 5-point Likert scale or a yes/no response. Consensus was defined as ≥66.7% panelist agreement or disagreement. Results: Twenty panelists completed round 1; 19 of the 20 panelists completed rounds 2 and 3. Panelists achieved a high level of consensus for using CCH for the treatment of patients with palpable cords and varying severity contractures representing one- or two-finger MP joint contractures, most one- or two-finger PIP joint contractures, and most combined MP and PIP joint contractures. Consensus for the treatment of PIP joint contractures was mostly achieved, but clinical scenarios related to recurrent PIP contracture with poor-quality skin and/or significant postfasciectomy scarring, boutonnière deformity, PIP contractures >70°, closed capsulotomy, and blood thinner use were modified, and then most (95.3%) statements reached consensus for agreement in round 2. In round 3, open-ended responses indicated that panelists considered CCH appropriate for most patients with Dupuytren disease. Conclusions: Consensus-based findings among expert hand surgeons with substantial CCH experience indicated that CCH has a wide-ranging application for the treatment of Dupuytren disease in patients with varying degrees of disease severity and functional impairment. Type of study/level of evidence: Therapeutic V.

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.

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.

Quality and Reliability Analysis of YouTube as a Source for Patient Education on Dupuytren's Contracture.

Purpose: This study seeks to assess the quality and reliability of YouTube videos on Dupuytren's contracture. Methods: The first 50 unique videos on Dupuytren's contracture were evaluated by searching YouTube for Dupuytren's contracture. Video metrics, source, and content type were recorded. Video reliability was assessed using the Journal of American Medical Association (JAMA) Benchmark criteria. Video educational quality was assessed using the Global Quality Score (GQS) and a Dupuytren's Contracture-Specific Score (DC-SS). Results: The total number of views for all 50 videos evaluated was 1,908,608 (mean, 38,172.16 ± 5,502.45 views). The mean reliability (JAMA) score was 2.21 ± 0.69 (range 0-4), the mean educational quality (GQS) score was 2.80 ± 1.28 (range 1-5), and the mean disease-specific (DC-SS) score was 6.05 ± 2.17 (range 0-15). Nonphysician health care professionals had the most popular videos, but the lowest DC-SS. GQS varied based on the video source, with physician-uploaded videos having the highest average quality scores. Physician source was an independent positive predictor of higher quality (GQS) (ß = 0.477). Conclusions: Videos on Dupuytren's contracture were frequently viewed on YouTube but had overall low educational quality and reliability. Of the videos that discussed collagenase as a treatment option, 40% failed to mention percutaneous needle aponeurotomy. Patients may be exposed to an incomplete set of treatment options. Educational content on YouTube should be interpreted cautiously and proper in-office education and high-quality resources for Dupuytren's contracture should be provided by physicians. Type of Study/Level of Evidence: Therapeutic IV.

MMP-1, MMP-8, and MMP-13 Gene Polymorphisms and Haplotype Is a Risk Factor for Dupuytren Contracture: A Case-Control Study.

BACKGROUND: There is an increased tissue expression of matrix metalloproteinases (MMPs) on Dupuytren contracture (DC). Genetic polymorphisms (single nucleotide polymorphism [SNPs]) in genes of these enzymes may individually influence these transcriptions. Haplotype analysis, which is the observation of a group of alleles, could be more useful to identify the association between SNPs and DC. The purpose of this study was to evaluate the influence of MMP-1 g.-1607 G>GG (rs1799750), MMP-8 g.-799 C>T (rs11225395), and MMP-13 g.-77 A>G (rs2252070) SNPs individually and in haplotype on DC. METHODS: A total of 60 patients with a clinical diagnosis of DC were evaluated and matched, according to age and gender, with the control group of 100 patients without this clinical diagnosis. Genomic DNA was extracted from saliva samples, and genotypes were obtained by polymerase chain reaction-restriction fragment length polymorphism. Statistical analysis of the results included Mann-Whitney U test, Chi-squared test, and PHASE and R software, with a significance level of 5%. RESULTS: The 3 SNPs studied showed significant differences in allele and genotype frequencies between the groups: 2G in MMP-1 (P = .018; odds ratio [OR] 1.80 (95% confidence interval [CI], 1.13-2.88)), T in MMP-8 (P = .015; OR 0.53 (95% CI, 0.33-0.88)), and A in MMP-13 (rs2252070) SNPs (P = .040, OR 0.54 (95% CI, 0.33-0.90)) are risk alleles. The global haplotype analysis indicated a significant difference between both groups. CONCLUSIONS: In conclusion, MMP-1 g.-1607 G>GG (rs1799750), MMP-8 g.-799 C>T (rs11225395), and MMP-13 g.-77 A>G (rs2252070) SNPs, individually and in haplotype, are a risk factor for DC, indicating that these SNPs may be a potential diagnostic and prognostic factor for DC.

Comparing Complications and Patient Satisfaction Following Injectable Collagenase Versus Limited Fasciectomy for Dupuytren's Disease: A Systematic Review and Meta-Analysis.

Dupuytren's disease (DD) is a fibroproliferative disorder that manifests as an abnormal growth of myofibroblasts, causing nodule formation and contractures and affecting digit function. If left untreated, these contractures can lead to a loss of mobility and potentially impact hand function. This systematic review critically compares and evaluates the existing literature on the complications and patient satisfaction following injectable collagenase Clostridium histolyticum (CCH) versus limited fasciectomy (LF) for DD. We performed a comprehensive search of the PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), The Cochrane Library, and Excerpta Medica database (EMBASE) databases from 2006 to August 2023. This research targeted all clinical studies involving adults who underwent injectable collagenase and/or limited fasciectomy in the management of DD. Out of the 437 identified studies, only 53 were considered eligible for our analysis, and merely 14 met our inclusion criteria. These selected studies encompassed a total of 967 patients with 1,344 treated joints, with an average follow-up duration of 19.22 (ranging from one to 84.06) months. Within this cohort, 498 joints from 385 patients underwent LF, while 846 joints from 491 patients received CCH injections. Notably, among the 491 patients treated with CCH, 1,060 complications were reported, averaging 2.15 complications per patient, with the most common being contusion/bruising/hematoma/ecchymosis (22.54%), and edema/swelling (18.96%). In contrast, among the 385 patients treated with LF, only 97 complications were reported, translating to 0.25 complications per patient, with the most frequent being paraesthesia or numbness (23.7%), scar sequelae like skin laceration, tear, fissure, or hypertrophic scar (23.7%), and neuropraxia or nerve injury (22.6%). Our meta-analysis indicates that paraesthesia or numbness is more frequently observed in LF than CCH injections, although without statistical significance, with a risk ratio (RR) of 0.39 (95% confidence interval (CI) 0.13-1.18, p-value 0.1). However, scar sequelae (hypertrophic scar, skin laceration, tear, or fissure) show a contrasting pattern, being more commonly associated with CCH injections than LF, with an RR of 1.98 (95% CI 0.26-14.85, p-value 0.51), which, upon eliminating the source of heterogeneity, becomes statistically significant, with an RR of 4.98 (95% CI 1.40-17.72, p-value 0.01). Our data revealed a higher frequency of complications with CCH compared to LF, although more severe adverse effects were observed in the LF group, such as neuropraxia or nerve injury. Scar sequelae were more common with CCH injections. Despite both treatments showing increased patient satisfaction at the final follow-up, CCH injection resulted in earlier improvements in satisfaction.

Incidence, Prevalence, and Outcomes of Hand Manifestations in Patients With Diabetes Mellitus: A Comprehensive Literature Review.

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.

Repeated percutaneous needle fasciotomy for recurrent Dupuytren's disease.

Percutaneous needle fasciotomy (PNF) is an attractive option for repeated application for recurrence. We found that extension deficit correction was similar after a first, second and third PNF, though the interval between treatments was longer after a first versus second PNF.

Collagenase Treatment for Dupuytren Contracture of the Metacarpophalangeal Joint After Arthrodesis of the Proximal Interphalangeal Joint.

Successful collagenase (Xiaflex) treatment of Dupuytren's contracture in the metacarpophalangeal joint is possible in the presence of previous arthrodesis of the proximal interphalangeal joint.

The Lambda Cord: An Anatomic Configuration of Radial-Sided Dupuytren Disease.

The thumb and first webspace are involved in a relatively low proportion of cases of Dupuytren disease of the hand (3%-28%). Given the rarity, there has been a paucity of literature regarding anatomic cord configurations and the surgical technique for the management of such radial-sided diseases. There are unique anatomic considerations in the thumb that warrant understanding prior to safe surgical exploration. A case of an anatomic variant of Dupuytren disease involving the thumb and first webspace treated with a webspace skin-sparing partial fasciectomy is described. The current literature regarding surgical management of Dupuytren disease affecting the thumb and first webspace is also briefly presented.

Let's Focus on the Fibrosis in Dupuytren Disease: Cell Communication Network Factor 2 as a Novel Target.

Dupuytren disease is a progressive, benign fibroproliferative disorder of the hands that can lead to debilitating hand contractures. Once symptomatic, treatment involves either surgical intervention, specifically fasciectomy or percutaneous needle aponeurotomy, or enzymatic degradation with clostridial collagenase. Currently, collagenase is the only pharmacotherapy that has been approved for the treatment of Dupuytren contracture. There is a need for a pharmacotherapeutic that can be administered to limit disease progression and prevent recurrence after treatment. Targeting the underlying fibrotic pathophysiology is critical. We propose a novel target to be considered in Dupuytren disease-cell communication network factor 2/connective tissue growth factor-an established mediator of musculoskeletal tissue fibrosis.

Objective and subjective assessment of Dupuytren's contracture.

This paper describes the evaluation options of Dupuytren's contracture by subjective and objective methods. There are various classification schemes named after their authors, including graphical representation for objective evaluation of the disease. Subjective assessment was performed in the form of a questionnaire for patients. The QuickDASH with a small specification for Dupuytren's contracture is the most commonly used questionnaire. The Southampton Dupuytren's Scoring Scheme questionnaire appears to be a higher specification. The classifications allow evaluation of treatment success to determine prognosis of the disease. The analysis of articles is based on PubMed search from the years 1967-2022, with 28 relevant articles were retrieved. Based on this analysis, the Tubiana classification appears to be the most appropriate one for patients with Dupuytren's contracture. Of patient questionnaires, the Southampton Dupuytren's Scoring Scheme meets these parameters.

A Decade of Complex Regional Pain Syndrome Following Orthopedic Wrist Surgery: A Case Report and a Literature Review.

Every day, people of all ages in the United States break bones, with traumatic injury being the most common way, and wrist injury being in the top five most common areas in which bones break. Traumatic fractures are managed with either surgical or nonsurgical approaches. The surgical approach utilizes ortho procedures such as internal fixation and reduction, while the nonsurgical approach consists of procedures like RICE, ace bandage, and so on. However, in rare cases, patients are left with a peculiar constellation of symptoms, which cause edema, pain, skin changes, and loss of function at the trauma site. This occurrence is termed complex regional pain syndrome. Here, we present the case of a 55-year-old female patient who suffered a traumatic wrist injury. The trauma was fixed by pinning ORIF orthopedic surgery, and the patient developed manifestations of complex regional pain syndrome around 10 days postoperatively. In this case report, we describe the variation and complexity of symptoms in the patient over the course of a decade after the original injury. The case report explains the pain management therapies that reduced the patient's symptoms and highlights the ones that were ineffective. We have included some less frequently used yet effective treatments and shed light on how this disease affected the patient's overall well-being.

Prospective analysis of grip strength and load distribution after surgical treatment of common diseases of the hand with novel's manugraphy® system.

BACKGROUND: Carpal tunnel syndrome, A1 annular pulley stenosis and Dupuytren's contracture are among the most common conditions of the hand. In this study, we investigated the impact of surgical procedure on hand grip strength and high-resolution spatial load distribution in individuals suffering from those diseases over a follow-up period of one year. MATERIALS AND METHODS: In this prospective study, data of 9 patients with carpal tunnel syndrome, 12 patients with A1 annular pulley stenosis and 7 patients with Dupuytren's contracture were evaluated. Only patients with unilateral disease were included providing the contralateral hand as an intra-individual control. Grip strength was measured with cylindrical instruments in two different sizes with respect to the hand size of the patients. Maximum and average values of grip strength as well as spatial load distribution in each finger, thenar, hypothenar and palm were analyzed. Data of the affected patients were collected preoperatively and 6 weeks, 6 months and 1 year postoperatively. Grip strength and spatial load distribution were compared preoperatively to postoperatively. In addition, DASH score, Levine score, 2-point discrimination and degree of flexion contracture were assessed. RESULTS: The patients with A1 annular pulley stenosis showed a significant increase in grip strength 6 months and one year postoperatively. Patients with carpal tunnel syndrome and Dupuytren's contracture showed no significant difference in grip strength over the course of time. An increase in the percentual grip strength of the thenar in patients with carpal tunnel disease and within the affected finger in A1 annular pulley stenosis was observed over the course of time. The DASH score was significantly lower in all patient cohorts one year postoperatively. CONCLUSION: Surgical procedure in carpal tunnel syndrome, A1 annular ligament stenosis and Dupuytren's contracture improves the functionality of the hand in everyday life. Some areas of the hand seem to compensate other weaker areas in grip strength.

Validation of a Handprint for Clinical Evaluation of Dupuytren's Contracture.

Objective We have developed a handprint-based method for visualizing and quantifying the palmar contact of patients with Dupuytren's contracture. The purpose of this study was to examine whether the generated handprint was useful for assessing the severity of flexion contracture of the fingers and for evaluating the therapeutic effects of collagenase clostridium histolyticum (CCH) injection for Dupuytren's contracture. Methods The handprint was created by applying medical-grade ethanol-containing hand sanitizer over the entire palmar surface of the affected hand and then pressing it on thermal paper for word processors. The reliability of the handprint was evaluated through test-retest of 10 healthy volunteers at an interval of 10 days, and the validity of the handprint was assessed using a flexion contracture model in which the little finger was fixed in an Alfence splint. In addition, we obtained handprints of the affected hand in 33 patients with unilateral Dupuytren's contracture both before CCH injection and at the final observation after injection to investigate the contact area of the hand (CAH) and the length of the hand (LH). The relationships between CAH, LH, total extension deficit angle (TEDA), and patient-reported outcome measures (Japanese Society for Surgery of the Hand Version of the Quick Disability of Arm, Shoulder, and Hand Questionnaire [Quick DASH-JSSH] and Hand20) were examined. Results The test-retest correlation coefficient was 0.9187 ( p < 0.001) for CAH and 0.9052 ( p < 0.001) for LH, indicating high reliability of the handprint. The ratios of CAH and LH decreased gradually as the contracture angle of the splinted finger increased. The handprint revealed a marked improvement of palmar contact after CCH injection for Dupuytren's contracture. Furthermore, the ratios of CAH and LH were strongly correlated with TEDA, Quick DASH-JSSH, and Hand20 before treatment. Conclusion Our handprint-based assessment method was extremely useful for clinical evaluation of CCH treatment for Dupuytren's contracture. Type of Study/Level of Evidence Therapeutic.

External Fixation Prior to Fasciectomy Leads to Substantial Improvement of Advanced Dupuytren's PIP Contractures at Mean Follow-up 15 Months.

BACKGROUND: The Digit Widget is an external fixation device that can be used to reverse proximal interphalangeal joint (PIPJ) contractures in the hand. Our hypothesis is that usage of the Digit Widget prior to fasciectomy in patients with severe Dupuytren's proximal interphalangeal (PIP) contractures will result in short-term improvement and maintenance of the PIPJ contracture after fasciectomy. METHODS: Patients who underwent placement of the Digit Widget soft tissue distractor prior to fasciectomy for Dupuytren's disease were identified between January 2015 and December 2018. Multiple fingers were considered separately. Patient Reported Outcome Measurement Information System (PROMIS) Physical Function (PF), Pain Interference, and Depression scores were collected. Patients treated for contractures from etiologies other than Dupuytren's were not included. Multiple linear regression was used to compare initial PIP contractures, PF scores, and final contractures. RESULTS: There were 28 fingers in 24 patients with average age of 56 ± 12 (30.5-69.9) years. Initial mean PIPJ contracture was 81° (50°-120°), which had corrected to 23° at time of removal. Average time between application and fasciectomy was 58 (28-112) days. At final follow-up, average 449 (58-1641) days, the average contracture was 39° (0°-105°). Contracture immediately following fasciectomy was found to be strongly correlated with the contracture at final follow-up. There was no statistical relationship between final PROMIS PF scores and final change in contracture. CONCLUSIONS: Digit Widget external fixation is an effective treatment for the correction of advanced PIPJ contractures related to Dupuytren's disease, with an average of 52% improvement in contracture at 15 months.
