Abstract
Aims Dupuytren's contracture is a benign, myoproliferative condition affecting the palmar fascia that results in progressive contractures of the fingers. Despite increased knowledge of the cellular and connective tissue changes involved, neither a cure nor an optimum form of treatment exists. The aim of this systematic review was to summarize the best available evidence on the management of this condition. Materials and Methods A comprehensive database search for randomized controlled trials (RCTs) was performed until August 2017. We studied RCTs comparing open fasciectomy with percutaneous needle aponeurotomy (PNA), collagenase clostridium histolyticum (CCH) with placebo, and CCH with PNA, in addition to adjuvant treatments aiming to improve the outcome of open fasciectomy. A total of 20 studies, involving 1584 patients, were included. Results PNA tended to provide higher patient satisfaction with fewer adverse events, but had a higher rate of recurrence compared with limited fasciectomy. Although efficacious, treatment with CCH had notable recurrence rates and a high rate of transient adverse events. Recent comparative studies have shown no difference in clinical outcome between patients treated with PNA and those treated with CCH. Conclusion Currently there remains limited evidence to guide the management of patients with Dupuytren's contracture. Cite this article: Bone Joint J 2018;100-B:1138-45.

Frost R, McClurg D, Brady M, Williams B. Optimising the validity and completion of adherence diaries: a multiple case study and randomised crossover trial. Trials 2016; 17:489. [PMID: 27724922 PMCID: PMC5057493 DOI: 10.1186/s13063-016-1615-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2016] [Accepted: 09/22/2016] [Indexed: 11/08/2023] Open
Abstract
BACKGROUND Diaries are the most commonly used adherence measurement method in home-based rehabilitation trials, yet their completion and validity varies widely between trials. We aimed to: (1) generate theory to explain this variation, (2) create an optimised diary and (3) evaluate the optimised diary's validity. METHODS Stage 1. DEVELOPMENT using a multiple case study approach, we collected trialist interviews (n = 7), trial publications (n = 16) and diaries (n = 7) from seven purposively sampled UK rehabilitation trials. We explored return rates, diary designs and trialists' ideas as to what affected diary completion and validity. Using explanatory case study analysis, we developed a diary optimisation model. Stage 2. EVALUATION we compared a diary optimised according to several model components to one nonoptimised according to the same components in a randomised AB/BA crossover trial. Healthy adults aged 60+ years without mobility impairments undertook a home-based 8-week walking programme. They recorded walking duration and frequency for 4 weeks per diary. We hypothesised that the optimised diary would possess greater validity for self-reported adherence to walking duration (criterion: the Activpal accelerometer), assessed during each diary's final week. Participants were blinded to the hypothesis. Secondary outcomes included test-retest reliability and acceptability. Ethical approval was granted from Glasgow Caledonian University. RESULTS Thirty-two out of 33 participants completed the study. Diaries did not significantly differ in validity, reliability or acceptability. Both diaries agreed closely with the Activpal when assessing duration adherence at a group level, however, inter and intraindividual variation in validity was high (mean difference (95 % limits of agreement (LOA): limits of agreement plot the difference between measurements collected using two different methods against their mean and thus assess the extent to which the two measures agree with each other)) optimised diary = 3.09 % (-103.3 to 109.5 %), nonoptimised diary = -0.34 % (-131.1 to 130.5 %), p = 0.732). We found similarly wide LOA for percentage of days adhered to and percentage of walks taken, whilst frequency adherence was underestimated. Participants rated both diaries as low-burden and equal numbers favoured each diary or were neutral. Preference appeared to impact minimally upon validity. CONCLUSION Group-level adherence diary data are likely to be valid. However, individual diary data lack validity, which raises concerns if using this data in calculations such as predicting functional outcomes. Different diary designs are likely interchangeable, though unanticipated high variation meant that this study was underpowered. TRIAL REGISTRATION The trial was not eligible for registration in a clinical trial database as diary measurement property outcomes, not clinical health outcomes of participants, were assessed.

Abstract
BACKGROUND Dupuytren's disease is a benign fibroproliferative disorder that causes the fingers to be drawn into the palm via formation of new tissue under the glabrous skin of the hand. This disorder causes functional limitations, but it can be treated through a variety of surgical techniques. As a chronic condition, it tends to recur. OBJECTIVES To assess the benefits and harms of different surgical procedures for treatment of Dupuytren's contracture of the index, middle, ring and little fingers. SEARCH METHODS We initially searched the following databases on 17 September 2012, then re-searched them on 10 March 2014 and on 20 May 2015: the Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane Library, the British Nursing Index and Archive (BNI), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, the Latin American Caribbean Health Sciences Literature (LILACS), Ovid MEDLINE, Ovid MEDLINE-In-Process and Other Non-Indexed Citations, ProQuest (ABI/INFORM Global and Dissertations & Theses), the Institute for Scientific Information (ISI) Web of Science and clinicaltrials.gov. We reviewed the reference lists of short-listed articles to identify additional suitable studies. SELECTION CRITERIA We included randomised clinical trials and controlled clinical trials in which groups received surgical intervention for Dupuytren's disease of the index, middle, ring or little finger versus control, or versus another intervention (surgical or otherwise). We excluded the thumb, as cords form on the radial aspect of the thumb and thus are not readily accessible in terms of angular deformity. Furthermore, thumb disease is rare. DATA COLLECTION AND ANALYSIS A minimum of two review authors independently reviewed search results to select studies for inclusion by using pre-specified criteria, assessed risk of bias of included studies and extracted data from included studies.We grouped outcomes into the following categories: (1) hand function, (2) other patient-reported outcomes (e.g. satisfaction, pain), (3) early objective outcomes (e.g. correction of angular deformity), (4) late objective outcomes (e.g. recurrence) and (5) adverse effects. MAIN RESULTS We included 14 articles describing 13 studies, comprising 11 single-centre studies and two multi-centre studies. These studies involved 944 hands of 940 participants; of these, 93 participants were reported twice in separate articles describing early and late outcomes of one trial. Three papers reported the outcomes of two trials comparing different procedures. One trial compared needle fasciotomy versus fasciectomy (125 hands, 121 participants), and the other compared interposition firebreak skin grafting versus z-plasty closure of fasciectomy (79 participants). The other 11 studies reported trials of technical refinements of procedures or rehabilitation adjuncts. Of these, three investigated effects of postoperative splinting on surgical outcomes.Ten studies (11 articles) were randomised controlled trials (RCTs) of varying methodological quality; one was a controlled clinical trial. Trial design was unclear in two studies awaiting classification. All trials had high or unclear risk of at least one type of bias. High risks of performance and detection bias were particularly common. We downgraded the quality of evidence (Grades of Recommendation, Assessment, Development and Evaluation - GRADE) of outcomes to low because of concerns about risk of bias and imprecision.Outcomes measured varied between studies. Five articles assessed recurrence; two defined this as reappearance of palpable disease and two as deterioration in angular deformity; one did not explicitly define recurrence.Hand function on the Disabilities of the Arm, Shoulder and Hand (DASH) Scale (scores between 0 and 100, with higher scores indicating greater impairment) was 5 points lower after needle fasciotomy than after fasciectomy at five weeks. Patient satisfaction was better after fasciotomy at six weeks, but the magnitude of effect was not specified. Fasciectomy improved contractures more effectively in severe disease: Mean percentage reduction in total passive extension deficit at six weeks for Tubiana grades I and II was 11% lower after needle fasciotomy than after fasciectomy, whereas for grades III and IV disease, it was 29% and 32% lower.Paraesthesia (defined as subjective tingling sensation without objective evidence of altered sensation) was more common than needle fasciotomy at one week after fasciectomy (228/1000 vs 67/1000), but reporting of complications was variable.By five years, satisfaction (on a scale from 0 to 10, with higher scores showing greater satisfaction) was 2.1/10 points higher in the fasciectomy group than in the fasciotomy group, and recurrence was greater after fasciotomy (849/1000 vs 209/1000). Firebreak skin grafting did not improve outcomes more than fasciectomy alone, although this procedure took longer to perform.One trial investigated four weeks of day and night splinting followed by two months of night splinting after surgery. The other two trials investigated three months of night splinting after surgery, but participants in 'no splint' groups with early deterioration at one week were issued a splint for use. All three studies demonstrated no benefit from splinting. The two trials investigating postoperative night splinting were suitable for meta-analysis, which demonstrated no benefit from splinting: Mean DASH score in the splint groups was 1.15 points lower (95% confidence interval (CI) -2.32 to 4.62) than in the no splint groups. Mean total active extension in the splint groups was 2.21 degrees greater (95% CI -3.59 to 8.01 degrees) than in the no splint groups. Mean total active flexion in the splint groups was 8.42 degrees less (95% CI 1.78 to 15.07 degrees) than in the no splint groups. AUTHORS' CONCLUSIONS Currently, insufficient evidence is available to show the relative superiority of different surgical procedures (needle fasciotomy vs fasciectomy, or interposition firebreak skin grafting vs z-plasty closure of fasciectomy). Low-quality evidence suggests that postoperative splinting may not improve outcomes and may impair outcomes by reducing active flexion. Further trials on this topic are urgently required.

Psychometric evaluation of the Disabilities of the Arm, Shoulder and Hand (DASH) with Dupuytren's contracture: validity evidence using Rasch modeling. BMC Musculoskelet Disord 2014; 15:361. [PMID: 25358527 PMCID: PMC4228176 DOI: 10.1186/1471-2474-15-361] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2014] [Accepted: 10/17/2014] [Indexed: 11/12/2022] Open
Abstract
Background Dupuytren’s contracture is a progressive, fibroproliferative disorder that causes fixed finger contractures and can lead to disability. With the advances of new therapeutic interventions, the necessity to assess the functional repercussions of this condition using valid, reliable and sensitive outcome measures is of growing interest. The Disabilities of the Arm, Shoulder and Hand (DASH) is one frequently used patient-reported outcome measure but its reliability and validity have never been demonstrated specifically for a population affected with Dupuytren’s contracture. The objective of this study was to evaluate the psychometric properties of the DASH, with focus on validity evidence using the Rasch measurement model. Methods Secondary analysis was performed on data collected as part of a randomised clinical trial. One hundred fifty-three participants diagnosed with Dupuytren’s contracture completed the DASH at four time points (pre-op, 3, 6 and 12 months post-op). Baseline data were analysed using traditional analysis and to test whether they adhered to the expectations of the Rasch model. Post-intervention data were subsequently included and analyzed to determine the effect of the intervention on the items. Results DASH scores demonstrated large ceiling effects at all time points. Initial fit to the Rasch model revealed that the DASH did not adhere to the expectations of the Rasch partial credit model (χ2 = 119.92; p < 0.05). Multiple items displayed inadequate response categories and two items displayed differential item functioning by gender. Items were transformed and one item deleted leading to an adequate fit. Remaining items fit the Rasch model but still do not target well the population under study. Conclusions The original version of the 30-item DASH did not display adequate validity evidence for use in a population with Dupuytren’s contracture. Further development is required to improve the DASH for this population.

J Hand Surg Am 2013; 38:1285-94.e2. [PMID: 23790420 DOI: 10.1016/j.jhsa.2013.04.012] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2012] [Revised: 04/05/2013] [Accepted: 04/06/2013] [Indexed: 02/02/2023]
Abstract
PURPOSE To clarify the efficacy and detrimental effects of orthoses used to maintain finger extension following surgical release of Dupuytren contracture. METHODS We conducted a single-center, randomized, controlled trial to investigate the effect of night extension orthoses on finger range of motion and hand function for 3 months following surgical release of Dupuytren contracture. We also wanted to determine how well finger extension was maintained in the total sample. We randomized 56 patients to receive a night extension orthosis plus hand therapy (n = 26) or hand therapy alone (n = 30). The primary outcome was total active extension of the operated fingers (°). Secondary outcomes were total active flexion of the operated fingers (°), active distal palmar crease (cm), grip strength (kg), and self-reported hand function using the Disabilities of the Arm, Shoulder, and Hand questionnaire (0-100 scale). RESULTS There were no statistically significant differences between the no-orthosis and orthosis groups for total active extension or for any of the secondary outcomes. Between the first postoperative measure and 3 months after surgery, 62% of little fingers had maintained or improved total active extension. CONCLUSIONS The use of a night extension orthosis in combination with standard hand therapy has no greater effect on maintaining finger extension than hand therapy alone in the 3 months following surgical release of Dupuytren contracture. Our results indicate that the practice of providing every patient with a night extension orthosis following surgical release of Dupuytren contracture may not be justified except for cases in which extension loss occurs after surgery. Our results also challenge clinicians to research ways of maintaining finger extension in a greater number of patients.

Abstract
Background Correction of digit deformities at or near the Joints is performed easily ; however, maintaining the result is often difficult either due to noncompliance of the patient to wear the postoperative splints or problems related to unequal growth of bones or normal tissues compared to the scarred or operated side. Objectives The aim of this study was to overcome the above mentioned problems for which we propose the "Distal d Digit Syndactyly" technique. Materials and Method This method is based on the concept of suturing the distal phalanx of the deformed digit to the normal adjoining finger to help prevent the recurrence of the anomaly during the child’s growth period or the very important three or four postoperative months of scar maturation in the adult. After the correction of deformity of the finger or toe, "Distal Syndactyly" is created by two flaps on the adjoining digits; one base is dorsally hinged and the other one volar and after elevating the flaps they are sutured together. During the three postoperative weeks care is taken that this attachment is not disrupted and after healing a "distal syndactyly" is created which is very durable and in children it stretches with growth and does not impede the digit’s growth. Results Eleven patients with congenital and traumatic digit anomalies were treated. The recurrence of the problem was prevented in 9 patients; in 2 patients with intact Syndactyly the contracture recurred by stretching the Syndactyly skin. The period of the “Joining” ranged from 6 months to three years and cosmetic appearance was acceptable to the patient and parents. Conclusion This technique by joining a deformed digit to a normally growing adjacent digit prevents the postoperative recurrence of the contracture or growth induced deviation in the digits of noncompliant patients especially children.

J Hand Surg Am 2012; 37:2095-2105.e7.

Abstract
PURPOSE To call attention to the wide variety of definitions for recurrence that have been employed in studies of different invasive procedures for the treatment of Dupuytren contracture and how this important limitation has contributed to the wide range of reported results. METHODS This study reviewed definitions and rates of contracture correction and recurrence in patients undergoing invasive treatment of Dupuytren contracture. A literature search was carried out in January 2011 using the terms "Dupuytren" AND ("fasciectomy" OR "fasciotomy" OR "dermofasciectomy" OR "aponeurotomy" OR "aponeurectomy") and limited to studies in English. RESULTS The search returned 218 studies, of which 21 had definitions, quantitative results for contracture correction and recurrence, and a sample size of at least 20 patients. Definitions for correction of contracture and recurrence varied greatly among articles and were almost always qualitative. Percentages of patients who achieved correction of contracture (ie, responder rate) when evaluated at various times after completion of surgery ranged from 15% to 96% for fasciectomy/aponeurectomy. Responder rates were not reported for fasciotomy/aponeurotomy. Recurrence rates ranged from 12% to 73% for patients treated with fasciectomy/aponeurectomy and from 33% to 100% for fasciotomy/aponeurotomy. Review of these reports underscored the difficulty involved in comparing correction of contracture and recurrence rates for different surgical interventions because of differences in definition and duration of follow-up. CONCLUSIONS Clearly defined objective definitions for correction of contracture and for recurrence are needed for more meaningful comparisons of results achieved with different surgical interventions. CLINICAL RELEVANCE Recurrence after surgical intervention for Dupuytren contracture is common. This study, which evaluated reported rates of recurrence following surgical treatment of Dupuytren contracture, provides clinicians with practical information regarding expected long-term outcomes of surgical treatment choices.

Abstract
Before surgery for Dupuytren's contracture, 54 patients with a proximal interphalangeal (PIP) joint flexion contractures of at least 30° were randomized to receive either a 3-month splinting protocol together with hand therapy under the direct supervision of hand therapists, or the same hand therapy alone. Extension deficit of the PIP joint (primary outcome measure), global perceived effect, pain intensity, comfort and complications were assessed at baseline and 1 year after surgery. In an intention-to-treat analysis, the group assigned to splint-plus-hand therapy had a mean reduction of 21° in flexion contracture after 1 year, compared with 29° in the group receiving hand therapy alone (p = 0.1). There was no difference between the groups regarding other parameters. After operative release of a Dupuytren's contracture, a postoperative protocol using a splint and hand therapy was no better than hand therapy alone in minimizing postoperative flexion contractures.

A questionnaire-based survey of participants' decisions regarding recruitment and retention in a randomised controlled trial - lessons learnt from the SCoRD trial. Contemp Clin Trials 2011; 32:363-8.

Abstract
Successful recruitment and retention on trials is critical to ensuring that adequate power is conferred, results are generalisable and trials are completed within the allocated time and resources. Nested within an existing pragmatic randomised controlled trial a process evaluation was conducted to explore the reasons for a much higher than anticipated recruitment (120% of required sample size) and retention rate (96% completed follow-up). A questionnaire was designed to ascertain patient's views on reasons affecting consent and retention. 148 patients still enrolled in the trial at their final follow-up were either given or mailed a questionnaire of which 102 were returned (69%). 96% rated the written information as very or somewhat important in their decision to consent. Verbal information given to them by the operating surgeon was considered very or somewhat important by 86% and the relative inconvenience was rated as important by 79% of patients. Reasons for consenting for a large proportion of patents were the wish to help in research which may benefit others in the future and the perception that this was an important and relevant study. There was also some evidence that patients weighed up the demands with the potential benefits to them. High levels of satisfaction were expressed with trial personnel and trial procedures. The inclusion of a trial process evaluation such as the one presented here is an efficient method for gathering information of participants' decisions regarding recruitment and retention in a trial and can help to inform the successful planning of future trials.

Abstract
BACKGROUND Contractures are a common complication of neurological and musculoskeletal conditions, and are characterised by a reduction in joint mobility. Stretch is widely used for the treatment and prevention of contractures. However, it is not clear whether stretch is effective. OBJECTIVES To determine the effects of stretch on contractures in people with, or at risk of, contractures. SEARCH STRATEGY Electronic searches were conducted on CENTRAL, DARE, HTA (The Cochrane Library); MEDLINE; CINAHL; EMBASE; SCI-EXPANDED; and PEDro (April 2009). SELECTION CRITERIA Randomised controlled trials and controlled clinical trials of stretch applied for the purpose of treating or preventing contractures were included. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, extracted data, and assessed risk of bias. The primary outcomes of interest were joint mobility and quality of life. The secondary outcomes were pain, spasticity, activity limitation and participation restriction. Outcomes were evaluated immediately after intervention, in the short term (one to seven days) and in the long term (> one week). Effects were expressed as mean differences or standardised mean differences with 95% confidence intervals (CI). Meta-analyses were conducted with a random-effects model. MAIN RESULTS Thirty-five studies with 1391 participants met the inclusion criteria. No study performed stretch for more than seven months. In people with neurological conditions, there was moderate to high quality evidence to indicate that stretch does not have clinically important immediate (mean difference 3 degrees ; 95% CI 0 to 7), short-term (mean difference 1 degrees ; 95% CI 0 to 3) or long-term (mean difference 0 degrees ; 95% CI -2 to 2) effects on joint mobility. The results were similar for people with non-neurological conditions. For all conditions, there is little or no effect of stretch on pain, spasticity, activity limitation, participation restriction or quality of life. AUTHORS' CONCLUSIONS Stretch does not have clinically important effects on joint mobility in people with, or at risk of, contractures if performed for less than seven months. The effects of stretch performed for periods longer than seven months have not been investigated.
