Lateral humeral condyle combined with ulnar olecranon fractures in pediatric patients: A retrospective study of treatment and outcomes.

This study aimed to conduct a retrospective review of pediatric patients with concomitant ipsilateral lateral humeral condyle fractures and further evaluate treatment approaches and patient outcomes. Inclusion criteria: age 4 to 14 years with the diagnosis of ipsilateral lateral humeral condyle and ulnar olecranon fractures, no history of fractures, and follow-up of at least 24 months. Excluded patients: patients with open fractures, history of elbow joint surgery, and associated neurovascular injury. Surgical methods include closed reduction and percutaneous pinning or open reduction and internal fixation with/or tension-band wiring. We measured clinical and radiographic evaluation. A total of 62 patients (22 girls and 40 boys) between January 2018 and January 2022 were included in this retrospective study. The average follow-up time was 29.2 ± 3.8 months. At the final follow-up, there were no cases of cubitus valgus deformity, nonunion, delayed union, malunion, and osteoarthritis. The postoperative average elbow flexion range was 135.1 ± 7.5°. The elbow extension range was 1.5 ± 2.3°. The average forearm pronation was 82.2 ± 3.6°. The average forearm supination was 84.1 ± 2.8°. According to the Kim score, the outcome was "excellent" in 45 cases and "good" in 17 cases. The average Mayo Elbow Performance Score was 92.5 ± 3.3 points. Reduction and internal fixation yielded satisfactory clinical outcomes in the management of these rare fractures.
