Factors affecting functional recovery after surgery and hand therapy in patients with Dupuytren's disease

Patients' perspectives of collagenase injection or needle fasciotomy and rehabilitation for Dupuytren disease, including hand function and occupational performance

PURPOSE

To describe patients' perspectives of collagenase injection or needle fasciotomy for Dupuytren disease (DD) including hand therapy, and their view of hand function and occupational performance.

MATERIALS AND METHODS

Interviews were performed with twelve patients who had undergone non-surgical treatment and rehabilitation for DD. Data was analysed using a problem-driven content analysis using the model of Patient Evaluation Process as a theoretical framework.

RESULTS

The participants' previous experiences influenced their expectations of the upcoming treatment and they needed information to be prepared for treatment. Treatment and rehabilitation had a positive impact on daily life and were regarded as effective and simple with quick recovery. However, there could be remaining issues with tenderness or stiffness. The participants expressed their belief in rehabilitation and how their own efforts could contribute to an improved result. Despite concerns about future recurrence participants described increased knowledge and sense of control regarding future needs.

CONCLUSION

Undergoing a non-surgical treatment and rehabilitation process for DD was regarded as quick and easy and can meet the need for improved hand function and occupational performance. Taking responsibility for one's own rehabilitation was considered to influence the outcome positively. The theoretical framework optimally supported the exploration of participants' perspective.Implications for rehabilitationTreatment of Dupuytren Disease (DD) with needle/collagenase combined with hand therapy was experienced as giving fast improvement in hand function and occupational performance.An individualized care process which satisfies the need for knowledge about the disease, prognosis, treatment options and rehabilitation can give individuals suffering from DD a sense of security.The need for active participation in the DD care process can vary and it is crucial to listen to individuals' opinions and needs.Individuals can take considerable responsibility for rehabilitation after non-surgical treatment for DD and regard it as important for the outcome.

Treatment practice for Dupuytren disease in Belgium before 2020: results from an online survey

The treatment of Dupuytren disease (DD) continues to evolve. New insights in risk factors for recurrence and new treatment modalities have changed the management strategies for DD over the past decades. However, several differences may remain between these insights and their clinical application. The current tendencies in management of Dupuytren disease, were investigated in a web-based survey. The survey was sent to all members of the Belgian Hand Group, the professional organisation of hand surgeons in Belgium. The participants indicated their preferred treatment for clinical cases and answered questions on the use and timing of splinting, physiotherapy, medication and adapting the management depending on fibrosis diathesis. These findings were compared to recommendations found in the literature. Forty out of 135 surveyed members of the Belgian Hand Group completed the survey and 7 responded incompletely, yielding a response rate of 35% for most questions. This is comparable to similar studies. There appeared to be still room for debate on surgical techniques for difficult cases. CCH use increased since reimbursement became available in Belgium, mainly due to satisfying clinical results for patient and surgeon. The survey demonstrated a wide variety in pre- and postoperative splinting protocols, but consensus existed with the literature on postoperative night-time application of orthoses for 7 to 12 weeks.

Return-to-Function Following Treatment of Dupuytren Contracture With Collagenase Clostridium Histolyticum Versus Fasciectomy

Background: Dupuytren contracture (DC) treatment with collagenase clostridium histolyticum (CCH) has lower associated treatment costs than fasciectomy, but real-world, postprocedure return-to-function data are limited. Methods: This retrospective study used a US claims database and included adults treated for DC with CCH or fasciectomy (first treatment = index date), who had continuous health plan enrollment ≥360 days preindex and ≥90 days postindex (ie, 90-day follow-up). Analgesic use and physical therapy (PT) and occupational therapy (OT) visits during the follow-up were used as surrogate markers for return-to-function. Results: Overall, 1654 and 2745 patients were included in the CCH and fasciectomy cohorts, respectively. A significantly lower percentage of patients in the CCH versus fasciectomy cohort used opioid analgesics (32.3% vs 82.7%; P < .0001), used nonsteroidal anti-inflammatory drugs (8.6% vs 17.2%; P < .0001), or had ≥1 DC-specific PT or OT visit during follow-up (PT, 38.9% vs 45.3% [P < .0001]; OT, 32.8% vs 38.0% [P = .0006]). The mean number of DC-specific PT and OT visits (PT, 2.5 vs 6.4 [P < .0001]; OT, 1.4 vs 1.9 [P < .0001]) per patient was significantly lower in the CCH versus fasciectomy cohort. Conclusions: This analysis using surrogate markers suggests that CCH treatment may allow earlier return-to-function than fasciectomy in adults treated for DC.

QuickDASH questionnaire items behave as 2 distinct subscales rather than one scale in Dupuytren's disease

STUDY DESIGN

Retrospective cohort BACKGROUND: Exploratory Factor Analysis (EFA) and structural equation modelling (SEM) assess relationships between questionnaire items and the constructs ("factors") measured by a questionnaire. The QuickDASH has not been subjected to these analyses in Dupuytren's disease.

PURPOSE

To undertake EFA and SEM to identify the factors measured by the QuickDASH in patients with Dupuytren's disease.

METHODS

We identified 750 cases of surgery for Dupuytren's disease at a single center with preoperative QuickDASH scores. We performed EFA on QuickDASH responses in R, using established methodology. Based on the EFA results, we conducted SEM in a training sample of 200 participants. A test SEM analysis was performed in a second, independent sample of 200 participants.

RESULTS

EFA suggested a 2-factor model. Items 1-6 measured one factor (we interpreted this as "hand function"), whereas items 9-11 measured a different factor ("hand symptoms"). Items 7 and 8 (social and work activities) did not reflect either of these factors well, and may be influenced by other variables. A structural equation model based on the EFA results, with 2 first-order factors, demonstrated excellent fit in our first SEM sample. This was confirmed with a second independent sample in a test analysis.

CONCLUSIONS

The QuickDASH PROM may measure 2 distinct factors in patients with Dupuytren's disease. This aligns with previous analyses of the full-length DASH PROM. Separation of the QuickDASH PROM into 2 sub-scales with distinct scores to measure "hand function" and "hand symptoms" may improve its structural validity in patients with Dupuytren's disease.

Contribution of revision amputation vs replantation for certain digits to functional outcomes after traumatic digit amputations: A comparative study based on multicenter prospective cohort

BACKGROUND

Traumatic digit amputations can result in significant impairment. Optimal surgical treatment is unclear for certain digits in various amputation patterns. Our aim was to compare the contribution of revision amputation vs replantation for each particular digit to functional outcomes.

MATERIALS AND METHODS

Prospective cohort study at three tertiary hospitals was conducted in China. Eligible participants were 3192 patients with traumatic digit amputations enrolled from January 1, 2014, to January 1, 2018. The primary outcome was Michigan Hand Outcomes Questionnaire (MHQ) scores 2 years after initial surgery. Secondary outcome was score on the Disabilities of the Arm, Shoulder, and Hand (DASH).

RESULTS

Of 3192 enrolled patients, 2890 completed the study. Main-effect linear regression showed that participants with replantation of thumb, index, long, and ring (proximal to the proximal interphalangeal [PIP] joint) fingers had significantly better MHQ scores compared to participants with the corresponding finger revision amputation. DASH results were comparable. Finger-finger interaction analyses conducted with multifactor dimensionality reduction (MDR) revealed that the small finger and ring finger had the smallest and greatest interactions with other fingers, respectively. After stratification by amputation level of thumb, index finger, or long finger, linear regression showed that replantation of the ring finger distal to the PIP joint resulted in better MHQ and DASH when the thumb or long finger was also traumatically amputated proximal to the IP/PIP joint.

CONCLUSIONS

Replantation of the thumb, index, long, and ring (proximal to PIP joint) fingers is preferable to revision amputation, regardless of amputation pattern. Replantation of the ring finger amputated distal to PIP was beneficial only when the thumb or long finger was amputated proximal to IP/PIP joint. Replantation or revision amputation of the small finger was indistinguishable in terms of functional outcome. Future investigations and clinical decisions should take into account the role of finger-finger interactions.

Factors Associated with the Development, Progression, and Outcome of Dupuytren Disease Treatment: A Systematic Review

BACKGROUND

The factors typically considered to be associated with Dupuytren disease have been described, such as those in the "Dupuytren diathesis." However, the quality of studies describing them has not been appraised. This systematic review aimed to analyze the evidence for all factors investigated for potential association with the development, progression, outcome of treatment, or recurrence of Dupuytren disease.

METHODS

A systematic review of the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, and Cumulative Index to Nursing and Allied Health Literature databases was conducted using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant methodology up to September of 2019. Articles were screened in duplicate. Prognostic studies were quality assessed using the Quality in Prognosis Study tool.

RESULTS

This study identified 2301 records; 51 met full inclusion criteria reporting data related to 54,491 patients with Dupuytren disease. In total, 46 candidate factors associated with the development of Dupuytren disease were identified. There was inconsistent evidence between the association of Dupuytren disease and the presence of "classic" diathesis factors. The quality of included studies varied, and the generalizability of studies was low. There was little evidence describing the factors associated with functional outcome.

CONCLUSIONS

This systematic review challenges conventional notions of diathesis factors. Traditional diathesis factors are associated with disease development and recurrence, although they are not significantly associated with poor outcome following intervention based on the current evidence.

Collagenase Clostridium histolyticum Injection Therapy Improves Health-related Quality of Life in Patients with Dupuytren's Disease

Objectives:

This study was conducted to investigate the changes in clinical and psychosocial outcomes in patients with Dupuytren’s disease after initial treatment with collagenase Clostridium histolyticum (CCH) injection.

Methods:

This study involved 14 patients with Dupuytren’s disease who underwent treatment with CCH injection. The range of motion of each phalangeal joint was measured before treatment and at 6 months posttreatment. The following assessments were also carried out pre- and posttreatment: the Geriatric Depression Scale Short – Japanese version (GDS-J) to evaluate depressive status, Hand 10 to assess hand health status, and EuroQol-5-dimension-3-level Japanese version to evaluate health-related quality of life

Results:

Significant improvements were found in metacarpophalangeal joint extension and proximal interphalangeal joint extension. Significant differences were also found between values before the initiation of CCH injection and those at 6 months posttreatment for the EuroQol index score and the EuroQol Visual Analog Scale (VAS). Significant positive correlations were found between the pre- to posttreatment change in GDS-J scores and for the change in Hand 10 scores. Moreover, a significant negative correlation was found between the change in GDS-J scores and change in EuroQol index scores/EuroQol VAS scores before and at 6 months after CCH injection.

Conclusions:

For patients with Dupuytren’s disease, CCH therapy directly improved the health-related quality of life. The degree of improvement of depressive status was associated with the degree of improvement of hand health status and health-related quality of life.

A systematic review identifying outcomes and outcome measures in Dupuytren's disease research

This systematic review summarizes the outcome reporting standards in Dupuytren's disease treatment research. A search of Ovid Medline, Ovid Embase, and CINAHL was conducted. Randomized controlled trials, cohort studies, and case series published between 1997 and 2017, investigating treatment of Dupuytren's disease with fasciectomy, fasciotomy, or collagenase, were eligible for inclusion. Range of motion was the most commonly reported outcome, appearing in 77% of included studies. Outcomes, such as range of motion, recurrence, and clinical success, were frequently defined, however many different definitions were used. We identified 37 unique measurement methods for range of motion, 28 for recurrence, and 25 for clinical success. Most outcomes were assessed at multiple time points, and only a few studies reported results according to established clinical significance thresholds. Development of a core outcome set will help standardize outcome reporting, and ensure future research in this field is relevant, interpretable, and amenable to systematic review and/or meta-analysis.

Factors predicting the 1-year outcome of collagenase treatment for Dupuytren's disease

INTRODUCTION

Several studies have investigated the clinical outcome after collagenase treatment for Dupuytren's disease in terms of range of motion of the affected finger. However, good objective clinical outcome defined by a small remaining flexion contracture does not necessarily translate into satisfactory patient-subjective hand function. The aim of the present study was to identify predictors of patient-reported as well as objective clinical outcome in patients 1 year after collagenase treatment for Dupuytren's disease.

MATERIALS AND METHODS

Socio-demographic and disease-related data of 92 Dupuytren patients were collected prior to the intervention. Flexion contracture of the most affected finger was measured at baseline and 1 year after treatment. Patients also completed the brief Michigan Hand Outcomes Questionnaire (brief MHQ) before the intervention and at 1-year follow-up. First, univariate correlations using Pearson's correlation coefficient of the baseline variables with the two target variables were investigated. All variables with r > 0.35 were selected for a multivariate linear stepwise backwards regression model.

RESULTS

The mean brief MHQ score increased between baseline (72 ± 14) and the 1-year follow-up (85 ± 15) (p ≤ 0.001) and baseline flexion contracture decreased from 76° (± 26) to 33° (± 31) (p ≤ 0.001). Higher hand function at baseline (R² = 0.31) and less flexion contracture (R² = 0.46) were identified as positive predictors for the outcome 1 year after collagenase treatment for Dupuytren's disease. Other variables such as age, gender, manual work and if the MCP or PIP joint was affected did not determine outcome in our patient series.

CONCLUSIONS

Collagenase treatment resulted in considerable improvement in flexion contracture as well as patient-reported hand function at the 1-year follow-up. Clinicians can expect better outcome after collagenase infiltration in patients with less flexion contracture and in patients showing good initial self-reported hand function.

Primary Contact Occupational Therapy Hand Clinics: The pull of an occupational perspective

BACKGROUND/AIM

Primary contact models of care are an emerging area of occupational therapy practice that aim to respond to the changing health-care landscape. There is a dearth of literature exploring an occupational perspective in primary contact roles, and literature in the broader scope of hand therapy has recognised that occupational therapists' practice often aligns with the biomedical worldview. Therefore, this study aimed to explore the practice of occupational therapists within Primary Contact Occupational Therapy Hand (PCOTH) Clinics from an occupational perspective.

METHOD

This ethnographic study gathered in-depth data through observations of primary contact hand therapy sessions, review of progress notes and interviews with occupational therapists. Qualitative data analysis was conducted using a three-stage process first at the item level, then pattern level and finally at the structural level. The research team collaboratively discussed all codes and then themes.

RESULTS

The push of the biomedical culture and the pull of an occupational perspective was conceptualised as an overarching theme shaping occupational therapists' practice in the primary contact clinics. Five themes emerged: bottom-up approach to an occupational perspective, an occupational perspective via informal discussion, occupational therapists' expectations of patients, occupational perspective on autopilot and blurred professional identity.

CONCLUSION

Occupational therapists working in primary contact roles were pushed by the biomedical culture of the setting. Despite this, there was still a pull towards an occupational perspective. This research provides an initial exploration of primary contact clinics, and highlighted the added bonus of an occupational perspective. The findings present a timely opportunity for occupational therapists to critically reflect on practice in PCOTH clinics.

The Role of Hand Therapy in Dupuytren Disease

The role of hand therapy in the treatment of Dupuytren disease varies depending on the patient and the procedure. There is limited evidence for hand therapy as a preventive treatment of Dupuytren disease. Before corrective treatment, the hand therapist can contribute with assessments to promote evaluation of outcome. After corrective treatment, hand therapy is tailored to each patient's needs and consists of orthoses, exercise, edema control, and pain or scar management. Orthoses are usually part of the hand therapy protocol after corrective procedures despite lack of strong supporting evidence and should be provided based on individual patient needs.

Anti-Tumour Necrosis Factor Therapy for Dupuytren's Disease: A Randomised Dose Response Proof of Concept Phase 2a Clinical Trial

Background

Dupuytren's disease is a common fibrotic condition of the hand that causes irreversible flexion contractures of the fingers, with no approved therapy for early stage disease. Our previous analysis of surgically-excised tissue defined tumour necrosis factor (TNF) as a potential therapeutic target. Here we assessed the efficacy of injecting nodules of Dupuytren's disease with a TNF inhibitor.

Methods

Patients were randomised to receive adalimumab on one occasion in dose cohorts of 15 mg in 0.3 ml, 35 mg in 0.7 ml, or 40 mg in 0.4 ml, or an equivalent volume of placebo in a 3:1 ratio. Two weeks later the injected tissue was surgically excised and analysed. The primary outcome measure was levels of mRNA expression for α-smooth muscle actin (ACTA2). Secondary outcomes included levels of α-SMA and collagen proteins. The trial was registered with ClinicalTrial.gov (NCT03180957) and the EudraCT (2015-001780-40).

Findings

We recruited 28 patients, 8 assigned to the 15 mg, 12 to the 35 mg and 8 to the 40 mg adalimumab cohorts. There was no change in mRNA levels for ACTA2, COL1A1, COL3A1 and CDH11. Levels of α-SMA protein expression in patients treated with 40 mg adalimumab (1.09 ± 0.09 ng per μg of total protein) were significantly lower (p = 0.006) compared to placebo treated patients (1.51 ± 0.09 ng/μg). The levels of procollagen type I protein expression were also significantly lower (p < 0.019) in the sub group treated with 40 mg adalimumab (474 ± 84 pg/μg total protein) compared with placebo (817 ± 78 pg/μg). There were two serious adverse events, both considered unrelated to the study drug.

Interpretation

In this dose-ranging study, injection of 40 mg of adalimumab in 0.4 ml resulted in down regulation of the myofibroblast phenotype as evidenced by reduction in expression of α-SMA and type I procollagen proteins at 2 weeks. These data form the basis of an ongoing phase 2b clinical trial assessing the efficacy of intranodular injection of 40 mg adalimumab in 0.4 ml compared to an equivalent volume of placebo in patients with early stage Dupuytren's disease.

An occupational perspective in hand therapy: A scoping review

Introduction

There have been calls for the occupational therapy profession to realign with its values around occupation. However, the profession faces challenges in practice areas that have historically been underpinned by a biomechanical approach, such as hand therapy. The aim of this scoping review was to describe what is known about an occupational perspective in the hand therapy literature.

Method

This scoping review utilised a recognised five-step approach. A search was conducted in four databases for papers published between 2005 and 2016. Numerical and thematic analyses were employed, using the Canadian Practice Process Framework as a theoretical framework.

Results

Fifty papers were included in the scoping review. Six themes were identified: the centrality of occupation; inconsistencies in terminology; where in the occupational therapy process?; informal discussion as a key occupational strategy; occupational therapists’ expectations of patients; and a bottom-up approach focusing on biomechanical strategies to implementing the plan.

Conclusion

Whilst there has been some integration of an occupational perspective into hand therapy literature, there are still challenges. Inconsistent terminology, the lack of an occupational perspective throughout the occupational therapy process and a bottom-up approach to interventions all demonstrate the continuing tensions between the biomechanical approach and an occupational perspective.

ICF components of outcome measures for mallet finger: A systematic review

STUDY DESIGN

Systematic review.

INTRODUCTION/PURPOSE

The purpose of this study was to systematically review outcome measures used for the assessment of the conservative management of mallet finger to determine if they characterize the International Classification of Functioning, Disability, and Health components of activity, participation, environmental factors, or quality of life.

METHODS/RESULTS

Five studies published within the last 10 years were included in the systematic review. A majority, 19 of the outcomes used by the authors, fell within the body functions and structures category. Six were related to activity, and 1 was related to participation. One was linked to environmental factors. Five were found to be not definable and related to quality of life.

DISCUSSION/CONCLUSION

This systematic review suggests that many outcome measures focus on body structures and functions in the current research on the conservative treatment of mallet finger injuries.
