Delayed post-traumatic trigger finger in a 14-year-old boy after blunt trauma. A case report.

Although trigger finger is a common phenomenon, it is a rare condition in children and even more infrequently caused by a traumatic event. A case of a 14-year-old boy is reported, who presented with a prominent palmar nodule over a triggering middle finger and progressive flexion contracture, 6 months after a fall on the outstretched hand. An operation with resection of the A1-pulley and resection of the nodule, that showed chondroid metaplasia and calcifications, resolved the problem completely.
