Background Dupuytren’s contracture (DC) is a fibrotic hand condition in which one or more fingers develop progressive flexion deformities. Quality of life is diminished due to disabling limitations in performing everyday activities. For DC patients treated with collagenase, referral for subsequent hand therapy is inconsistent. It is unknown whether subsequent hand therapy is beneficial compared to no therapy. The purpose of this study is to determine whether hand therapy improves DC patients’ performance of and satisfaction with performing everyday activities one year after collagenase treatment. Methods We will conduct a randomised controlled trial with two treatment groups (hand therapy vs. control) of DC patients who have received collagenase treatment. DC patients with contracted metacarpophalangeal joint(s) (MCPJ) (hand therapy, n  = 40; control, n = 40) and those with proximal interphalangeal joint(s) (PIPJ) involvement (hand therapy, n = 40; control, n = 40) comprise two subgroups, and we will study if the treatment effect will be different between both groups ( n  = 160). Patients with a previous injury or treatment for DC in the treatment finger are excluded. Hand therapy includes oedema and scar management, splinting, movement exercises, and practice of everyday activities. The main outcome variable is patients’ performance of and satisfaction with performing everyday activities, as assessed with the Canadian Occupational Performance Measure. Secondary outcomes are DC-specific activity problems, as assessed with the Unité Rhumatologique des Affections de la Main scale, and active/passive flexion/extension of treated joints and grip force using standard measuring tools, and self-reported pain level. Demographic and clinical variables, degree of scarring, cold hypersensitivity, number of occupational sick-leave days are collected. Self-reported global impression of change will be used to assess patient satisfaction with change in hand function. Assessments are done pre-injection and 6 weeks, 4 months, and 1 year later. Standard univariate and multivariate statistical analyses will be used to evaluate group differences. Discussion This study aims to assess whether hand therapy is beneficial for activity-related, biomechanical, and clinical outcomes in DC patients after collagenase treatment. The results will provide an objective basis for determining whether hand therapy should be conducted after collagenase treatment. Trial registration This study has been registered at ClinicalTrials.gov as NCT03580213 (April 5, 2018).

Dupuytren’s disease is a common fibroproliferative disorder that primarily affects the palm of the hand. While the disease is known for its characteristic palmar contractures, it also has a potential impact on the extensor mechanism of the hand, resulting in the development of boutonniere deformity, swan-neck deformity, and persistent metacarpophalangeal joint contracture due to extensor capsule stretching and tendon instability. These imbalances are challenging to correct under general or regional anesthesia. Wide awake local anesthesia without a tourniquet allows active range of motion and intraoperative patient collaboration. By understanding the underlying mechanisms and structures involved in these deformities and correcting them under local anesthesia without a tourniquet, hand surgeons can become more confident in correcting the deformity, demonstrating it to the patient, optimizing the rehabilitation protocol, and improving patient outcomes. •Examines Dupuytren's disease impact on extensor mechanism imbalances in the hand.•Principles of corrective surgery for extensor deformities secondary to Dupuytren.•Discuss pre- and postoperative hand therapy strategies.

Frozen shoulder is a painful condition that often requires surgery and affects up to 5% of individuals aged 40–60 years. Little is known about the causes of the condition, but diabetes is a strong risk factor. To begin to understand the biological mechanisms involved, we aimed to identify genetic variants associated with frozen shoulder and to use Mendelian randomization to test the causal role of diabetes. We performed a genome-wide association study (GWAS) of frozen shoulder in the UK Biobank using data from 10,104 cases identified from inpatient, surgical and primary care codes. We used data from FinnGen for replication and meta-analysis. We used one-sample and two-sample Mendelian randomization approaches to test for a causal association of diabetes with frozen shoulder. We identified five genome-wide significant loci. The most significant locus (lead SNP rs28971325; OR = 1.20, [95% CI: 1.16–1.24], p = 5x10 -29 ) contained WNT7B . This variant was also associated with Dupuytren’s disease (OR = 2.31 [2.24, 2.39], p<1x10 -300 ) as were a further two of the frozen shoulder associated variants. The Mendelian randomization results provided evidence that type 1 diabetes is a causal risk factor for frozen shoulder (OR = 1.03 [1.02–1.05], p = 3x10 -6 ). There was no evidence that obesity was causally associated with frozen shoulder, suggesting that diabetes influences risk of the condition through glycemic rather than mechanical effects. We have identified genetic loci associated with frozen shoulder. There is a large overlap with Dupuytren’s disease associated loci. Diabetes is a likely causal risk factor. Our results provide evidence of biological mechanisms involved in this common painful condition.

Dupuytren’s disease (DD) is a common fibro-proliferative disorder of the palm. We estimated the risk of serious local and systemic complications and re-operation after DD surgery. We queried England’s Hospital Episode Statistics database and included all adult DD patients who were surgically treated. A longitudinal cohort study and self-controlled case series were conducted. Between 1 April 2007 and 31 March 2017, 121,488 adults underwent 158,119 operations for DD. The cumulative incidence of 90-day serious local complications was low at 1.2% (95% CI 1.1–1.2). However, the amputation rate for re-operation by limited fasciectomy following dermofasciectomy was 8%. 90-day systemic complications were also uncommon at 0.78% (95% CI 0.74–0.83), however operations routinely performed under general or regional anaesthesia carried an increased risk of serious systemic complications such as myocardial infarction. Re-operation was lower than previous reports (33.7% for percutaneous needle fasciotomy, 19.5% for limited fasciectomy, and 18.2% for dermofasciectomy). Overall, DD surgery performed in England was safe; however, re-operation by after dermofasciectomy carries a high risk of amputation. Furthermore, whilst serious systemic complications were unusual, the data suggest that high-risk patients should undergo treatment under local anaesthesia. These data will inform better shared decision-making regarding this common condition.

•Approximately half of type 2 diabetes mellitus individuals suffer from upper extremity musculoskeletal disorders.•Musculoskeletal disorders are prevalent bilaterally in thirty-two percent of individuals.•Limited joint mobility and frozen shoulder are the most prevalent disorders.•The proportion of limited joint mobility was more than frozen shoulder.•Amongst all disorders, frozen shoulder leads to maximum disability, followed by limited joint mobility and trigger finger. Cross-sectional Globally, diabetes is a leading cause of disability with an increased prevalence rate in the past three decades. Chronic diabetes has been shown to affect collagenous tissue which often leads to subsequent musculoskeletal complications. Despite increasing prevalence of musculoskeletal disorders, the proportion and distribution of types of upper extremity musculoskeletal disorders resulting in disabilities is poorly understood. This cross-sectional study aims to gather data on the prevalence, proportion and distribution of upper extremity musculoskeletal disorders among individuals with Type 2 Diabetes Mellitus. Further, this study examines the relationship between common upper extremity disorders and the resulting disability among individuals with Type 2 Diabetes Mellitus. 170 individuals diagnosed with Type 2 Diabetes Mellitus were recruited at a tertiary care hospital. Routine upper extremity assessments were performed to identify the presence of Frozen Shoulder (FS), Limited Joint Mobility (LJM), Trigger Finger, Carpal Tunnel Syndrome (CTS), and Dupuytren's Contracture. Disability was measured using the Disabilities of arm, shoulder, and hand (DASH) questionnaire. Descriptive statistics, one-way analysis of variance, Tukey's test, and Pearson's test were used to examine the prevalence, proportion and distribution of musculoskeletal disorders and disabilities among individuals with type 2 Diabetes Mellitus. 83(48.9%) participants had one or a combination of multiple musculoskeletal disorders of the upper extremity. The proportion of LJM, FS, CTS, Trigger Finger, and Dupuytren's Contracture were n = 46(27.1%); n = 43(25.3%); n = 16(9.4%); n = 8(4.7%); n = 5(2.9%) respectively. Disability scores on the DASH were 25.8 ± 14.5, 10.3 ± 11.9, and 10.6 ± 10.4 respectively for individuals with FS, LJM and Trigger Finger. DASH scores were highest in individuals with both CTS and FS, 29.8 ± 19.3. Duration of diabetes was significantly associated (r = 0 .19; P < .01) with the disability scores on DASH. The prevalence of musculoskeletal disorders in people with type 2 Diabetes mellitus remains high despite advances in medical management over the last two decades. The overall prevalence of hand disorders (LJM, CTS, Dupuytren's contracture, Trigger Finger) was higher than shoulder disorders (FS), e.g. frozen shoulder. People with a diabetes that had a diagnosed upper extremity conditon had more upper extremity disability, than those with diabetes but no diagnosed hand condition, Disability was highest for frozen shoulder and lowest for Dupuytren's diagnoses. Carpal tunnel syndrome was the most disabling hand condition. People with diabetes should be screened for upper extremity diagnoses that could limit their function. Poeple with disability resulting from hand disorders was lower than the shoulder disorders. A combination of hand and shoulder disorders resulted in greater disability.

Qualitative descriptive. Dupuytren's disease (DD) is a chronic hand condition causing impairment in hand function. Research describing persons' experiences of living with DD is limited. Understanding the subjective experience of illness is valuable for planning and implementing health-care services. To explore experiences among men living with an impaired hand function due to DD and the consequences of the disease for daily activities. Interviews were conducted with 21 men before surgery. The model of the patient evaluation process guided data collection. Data were analyzed using problem-driven content analysis. Participants described DD as a chronic disease caused by heredity, previous injury, hard work, or aging. DD was, according to the participants, an uncomfortable and sometimes painful condition, causing a feeling of constant stiffness in the affected hand. DD could cause participants to have fear of hurting the hand, feelings of shame or embarrassment, and a sense of being old. Participants handled the deteriorating hand function by avoiding or refraining from activities, adapting their performance, or performing activities with less quality. The ideal hand function was seen as being able to use the hands without effort. The diverse experiences of DD and if the hand is experienced as something that causes distress can be understood further using body-self dialectic and Gadow's states of embodiment, as well as the process of adapting and learning to live with the functional limitations. A clinical implication for hand therapy is to acknowledge patients' individual experiences and support self-modifications and development of new skills. •DD was described as a chronic disease causing a constant stiffness in the hand.•DD is also an uncomfortable and sometimes painful condition.•Consequences of DD were connected to the participants' view of their hand function.•DD caused fear of hurting the hand, feelings of shame or a sense of being old.•The participants avoided or refrained from activities or adapted their performance.

Background Advanced glycation end products are associated with aging, hyperglycemia, and oxidative stress. Accumulation of advanced glycation end products can cause various pathological conditions; however, the association of Dupuytren’s disease with advanced glycation end products has not been demonstrated yet. The aim of this study is to investigate the association of Dupuytren’s disease with advanced glycation end products. Methods Normal palmar fascia from five patients with carpal tunnel syndrome (control group) and Dupuytren’s cords from five patients (Dupuytren’s disease group) were harvested. The tissues were stained using an anti-advanced glycation end products antibody, anti-receptor for advanced glycation end products antibody, and an anti-reactive oxygen species modulator 1 antibody. The expression of nicotinamide adenine dinucleotide phosphate oxidase-1 and nicotinamide adenine dinucleotide phosphate oxidase-4 genes was also assessed using real-time PCR. For in vitro analysis, the cells harvested from the control and Dupuytren’s disease groups were used. After 3 days of exposure to four types of media (control group, control + advanced glycation end products group, Dupuytren’s disease group, Dupuytren’s disease + advanced glycation end products group), superoxide detection reagent was detected using a total reactive oxygen species/superoxide detection kit. Results Immunostaining of the palmar fasciae of the Dupuytren’s disease group showed higher expressions of advanced glycation end products and receptor for advanced glycation end products than that in the control group. The expression of nicotinamide adenine dinucleotide phosphate oxidase oxidase-1 and nicotinamide adenine dinucleotide phosphate oxidase-4 as well as reactive oxygen species modulator 1, an oxidatively damaged protein, was also higher in the Dupuytren’s disease group than in the control group. In an in vitro cell culture, the addition of advanced glycation end products to the Dupuytren’s disease-derived cells produced more superoxide free radicals. Conclusions These data suggest that the advanced glycation end products receptor for advanced glycation end products interaction produced free radicals via nicotinamide adenine dinucleotide phosphate oxidase activation in Dupuytren’s disease patients. Further studies are required to confirm these results.

Diabetes mellitus (DM) is a chronic systemic disease with a wide range of complications, including complications in the musculoskeletal system. DM is a common disease in nearly all countries and continues to increase in numbers and significance. Approximately 90 % of patients have type 2 DM which is caused by resistance to insulin. Type 1 DM results from an absolute deficiency of insulin due to an autoimmune destruction of insulin-producing beta cells within the pancreas. Diabetic patients suffer from diverse rheumatic conditions that affect their life quality. This article reviews the rheumatic conditions that are associated with DM and the pathophysiologic relationships that might link these conditions; it also summarizes recent advances in the field of diabetes and rheumatic conditions. The rheumatic conditions that are discussed in this review include limited joint mobility, Dupuytren’s contracture, flexor tenosynovitis, carpal tunnel syndrome, adhesive capsulitis, diffuse idiopathic skeletal hyperostosis, neuropathic osteoarthropathy, diabetic muscle infarction, crystal induced arthritis, osteoarthritis, and reflex sympathetic dystrophy.

Description Palmar and plantar fibromatosis are benign, painless thickening in the aponeurosis of the hands and feet, respectively. 1 Both forms of superficial fibromatoses can manifest as single or multiple nodular swellings resulting from localised proliferation of abnormal fibrous tissue in sites of predilection. 2 Although, the rheumatological and characteristics imaging features of these rare diseases are well documented in literature, 3 there are no reports of an oral manifestation.
