Effectiveness of Splinting After Collagenase Injection

Patients with Dupuytren disease that meet inclusion criteria will be consented to participate. All patients will be randomized to splint or no splint group prior to treatment. Baseline data will be collected prior to treatment and will include demographics, measurement of joint flexion contracture(s) with a standard finger goniometer, and QuickDASH scores. All patients that participate will receive 1 injection of 0.58 mg of CCH into cord. After 24-48 hours, if needed, patient will return to clinic for extension manipulation of treated finger(s) to help facilitate rupture of cord. Following injection and/or manipulation, all patients will be instructed to perform a series of finger exercises daily that they will receive from a hand therapist. In addition, patients assigned to the splint group will be fitted for a static night splint that they will be instructed to wear nightly for 4 months. Splint compliance will be recorded by a survey at each follow up visit. Patients will return to clinic for routine follow up care at 1 month and 4 months during which their degree of contracture(s) and outcomes will be measured and recorded. The primary outcome measures of this study are improvement in active extension deficit of each joint and total active extension of each digit, in degrees. The secondary outcome measures are QuickDASH scores and patient satisfaction.
