In total, 25 patients with soft tissue defects that occurred after severe Dupuytren's contracture release were treated using a perforator flap from the ulnar palm. Improvements in symptoms and functionality were assessed and compared before and after surgery. Data regarding the degree of contracture, two-point discrimination, and the total active motion (TAM) scale of the affected hand were collected by the same physician at the specified time points (preoperative, postoperative, and final follow-up), along with an evaluation of the donor and recipient areas of the flap. Concurrently, patients completed the visual analog scale (VAS) and disability of arm, shoulder, and hand (DASH) questionnaires.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All 25 flaps survived uneventfully, and the wound healed primarily. The follow-up time was 15\u201326\u2005months (average, 20.48\u2005months). At the final follow-up, the patient satisfaction score related to flap appearance ranged from 4 to 5 (mean, 4.72). The average two-point discrimination value of the flap was 5.52\u2009\u00b1\u20090.97\u2005mm. The contracture of the affected hand was improved with a mean TAM of 229\u00b0\u2009\u00b1\u200916.75\u00b0.
