From August 2007 to January 2012, 32 patients undergoing surgery for medial humeral epicondyle fractures in our hospital were randomized into group A (traditional Kirschner wire) or group B (absorbable cartilage nail). The same surgical team performed the operations, and patients were followed for over a year. Group A had open reduction with K-wire fixation, and group B was fixed with absorbable cartilage nails. The Bede scoring system was used to evaluate elbow function at follow-up.
