Dupuytren’s disease is a common condition in hand surgery. The fifth finger is frequently affected, pre- senting the highest recurrence rate after surgical treatment. The ulnar lateral-digital flap is used when a skin defect prevents direct closure after fasciectomy of the fifth finger at the level of the MP joint. Our case series comprises of 11 patients undergoing this procedure. Their mean preoperative extension deficit was 52° at the MP joint and 43° at the PIP joint. Full extension of the MP joint and a mean of 8° extension deficit at the PIP joint was achieved with surgery. All patients maintained full extension at the MP joint, with a follow-up of 1 to 3 years. Minor complications were reported. The ulnar lateral digital flap is a simple and reliable alternative when surgically treating Dupuytren’s disease of the fifth finger.
