ABSTRACT
OBJECTIVE: To test the convergent validity and ease of use of the Unité Rhumatologique des Affections de la Main (URAM) scale for patients with Dupuytren's disease. METHODS: Patients were prospectively included. We compared the convergent validity of the URAM scale, the Cochin Hand Function Scale (CHFS) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, in terms of their correlation with the Tubiana score and self-assessed disability on a visual analog scale (VAS). Pearson's correlation was used for the convergent validity study. The response time for questionnaire completion was the outcome for ease of implementation. RESULTS: We included 53 patients with Dupuytren's disease in the convergent validity study and 30 other patients with the disease in the time-response assessment. The URAM scale showed strong convergence with the Tubiana scale (r=0.64) and self-assessed disability on a VAS (r=0.69). Convergence with the Tubiana and self-assessed disability was higher for the URAM scale than the CHFS or DASH questionnaire. The mean [SD] response time was shorter for the URAM scale than the CHFS or DASH questionnaire (42 [20] vs 71 [35] and 103 [59] s, respectively, P<0.0001). CONCLUSIONS: The results reinforce the psychometric merits of the URAM scale. Furthermore, the response time for assessing disability was shorter with the URAM scale than the CHFS or DASH questionnaire. This evidence supports the high recommendation for the use of the URAM scale in clinical practice and clinical studies to assess disability in Dupuytren's disease.

OBJECTIVE: To our knowledge, no functional outcome measure has been developed and validated for Dupuytren's disease. We aimed to develop and validate a patient-reported functional outcome measure for Dupuytren's disease. METHODS: Patients with Dupuytren's disease (n = 9) and medical experts (n = 7) provided input and opinions about limiting activities that were difficult to perform because of Dupuytren's disease for item generation. The provisional scale was studied in an independent sample of patients (n = 85) for item reduction according to response distribution, reliability, redundancy, and loading in a 1-factor solution. The final scale was evaluated as follows: reliability using Cronbach's alpha coefficient and test-retest intraclass correlation coefficient from the previous 85-patient population, and construct validity and responsiveness after needle aponeurotomy in another independent 53-patient sample. For construct validity, convergent validity and divergent validity were tested. The clinically important change was estimated relative to a 1-point categorical change on the Tubiana scale. RESULTS: A 52-item provisional scale was generated and reduced to the final 9-item scale called the Unité Rhumatologique des Affections de la Main (URAM) scale (total score 0-45). The scale showed good to excellent reliability and suitable construct validity. The URAM score improved after needle aponeurotomy: the standardized effect size was 0.56. The estimated clinically important change of the URAM scale was 2.9 points. CONCLUSION: We provide the first patient-reported functional measure for Dupuytren's disease. The URAM scale demonstrated suitable psychometric properties, and is short and convenient enough for easy use in daily practice and in clinical studies.

AIM: To assess the safety and efficacy of multi-needle aponeurotomy (MNA) for advanced Duputren's disease. METHODS: This prospective study included patients with age more than 17 years, Dupuytren's contracture with palmo-digital or poly-digital involvement, presumed NA number needed to treat>4, and availability for at least 1-month follow-up after MNA. Outcome measures were Tubiana score and passive extension deficit, after MNA and at 1 and 6 months; self-assessed disability and satisfaction at 1 and 6 months; and adverse events (AEs). RESULTS: Thirty patients were included. MNA was performed on 37 hands and 99 rays. Among 25 assessed MNA sessions for treatment-related discomfort, patients considered 22 (88%) not at all to moderately painful. Six minor AEs, representing 2 for every 100 NAs, were reported. Tubiana scores at baseline (5.3±2.3, n=35) were improved after treatment (1.7±1.8, n=32, P<0.0001), at 1 month (2.2±1.4, n=26, P<0.0001) and at 6 months (2.8±2.7, n=19, P<0.01). Passive extension deficit was greatly reduced after treatment and persisted at follow-up. Disability scores at baseline (27.6±26.9, n=37) were reduced at 1 month (13.2±19.5, n=26, P=0.02) and at 6 months (5.2±11.6, n=20, P<0.001). Patients were highly satisfied at 1 month (100%, n=25) and 6 months (95%, n=19). CONCLUSION: MNA appears safe and effective for advanced Dupuytren's disease. It could become a treatment of reference and contribute to reducing the need for surgery in this indication.
