The isolated medial humeral epicondyle fracture treated nonoperatively: does fracture displacement change over time?

This study explores the change in the position of the fragment in isolated, displaced, medial humeral epicondyle fractures in children. In this series, 34 patients (mean age 11.0 years) were treated nonoperatively by cast immobilization with no attempt at closed fracture reduction. A statistically significant association was found between the position of the fracture fragment at the time of initial fracture compared with 3 weeks after fracture (P=0.015). Twenty-six of 34 patients (76.5%) showed spontaneous improvement in fragment position. These findings support the practice of treating significantly displaced medial epicondyle fractures nonoperatively.
