Purpose The main goal of this study was to retrospectively evaluate the clinical, functional and radiographic outcomes of displaced medial epicondyle fractures with or without associated elbow dislocation in children undergoing surgical treatment and to evaluate upper-extremity function with the Quick Disbilities of the Arm, Shoulder and Hand (Quick DASH) questionnaire. The hypothesis was that patients with associated elbow dislocation would have similar functional outcome to patients with displaced fractures with or without intraarticular entrapment of the medial epicondyle. Methods A review of medical charts was performed to identify all children and adolescents who underwent surgical treatment for displaced medial epicondyle humeral fractures managed at a single institution. Patients with a closed fracture on plain radiographs, presence of growth cartilages and managed surgically were included in the study. Fractures were radiologically assessed on anteroposterior and lateral radiographs and rated according to Papavasiliou and Crawford classification. Functional outcome was measured with the Quick DASH questionnaire. Sixty-six patients met inclusion criteria, and 38 children presented with isolated displaced medial epicondyle fracture (Group A: type II and type III) and 28 with medial epicondyle fractures associated with elbow dislocation (Group B: type IV). Results The Papavasiliou and Crawford system classified 36 fractures as type II (54.6%), two (3%) as type III and 28 as type IV (42.4%). All patients underwent open reduction. Fracture fixation was performed with K-wires in 26 (35%) children and a with single screw in 40 (65%). Mean followup was 37.5 months (range, 12–68). Overall complication rate was 18%. In particular, three adverse events (3/38, 8%) were recorded in Group -A and nine (9/28, 32%) in Group B (p = 0.003). Mean Quick DASH score at final follow-up was 4.6 ± 3.8 (range, 0–15.9) and was not significantly different between Groups A (5.4 ± 4.3; range, 0–15.9) and B (4.1 ± 3.5; range, 0–15.9) (p > 0.05). Conclusions Children with type II, III and IV medial epicondyle fractures undergoing surgical treatment have good radiological, clinical and functional outcome but warrant special attention to detect intra-articular entrapment of the broken epicondyle. In these cases, both patient and family should be warned of the potential risk of loss of elbow range of motion and possibly poor functional outcome, especially if treatment is delayed.
