Comparative risk of ulnar nerve injury in pediatric supracondylar humeral fractures: a multicenter evaluation of Kirschner wire fixation techniques.

Purpose: This multicenter, retrospective cohort study aimed to compare the risk of ulnar nerve injury in pediatric supracondylar humeral fractures treated with percutaneous lateral-pins, blinded-crossed-pins, and crossed-pins with a mini-incision.

Methods: Data were collected from 1705 children treated between January 2010 and December 2023 at four orthopedic centers in Colombia. The incidence of postoperative ulnar nerve injury was compared among three fixation techniques: lateral-pin, blinded-crossed-pin, and crossed-pin with a mini-incision.
