Functional outcomes, diagnostic imaging, athlete management, union rates, ulnar nerve symptoms, surgical methods, surgical positioning, and posttreatment protocols were categorized and recorded. For the nonoverhead athlete with an intermediately displaced fracture without an associated instability event during the injury, consideration can be given for nonoperative management. uninjured stressed elbow was used as a control to assess valgus instability. Lee HH, Shen HC, Chang JH, et al. Am J Sports Med. During the throwing motion, most of the valgus torque resisted at the elbow is from late cocking through the acceleration phase when the elbow is in a flexed position. Open elbow dislocation without fracture in the pediatric age group has been reported very rarely in … They represent about 3–6% of all pediatric elbow injuries . To better understand patient results with operative fixation, we reviewed the outcomes of operatively treated medial epicondyle fractures. The mechanism of injury is usually a valgus elbow force produced by a fall on the outstretched hand or by overhead throwing. Medial condylar fractures are a rare pattern of fracture and managed in a similar manner to lateral condylar fractures. Anterior displacement of the medial epicondyle results in excess tension (B) or laxity (D and F) in the anterior band of the ulnar collateral ligament at different degrees of elbow flexion. This usually occurs in children. A total of 8 patients were included in their study (5 treated nonoperatively and 3 treated operatively). Patients are allowed to gradually return to sport once they are pain free, have full elbow/forearm strength and range of motion, and have evidence of radiographic union.

Functional outcomes for patients were mostly good following operative and nonoperative management. This will facilitate postoperative evaluation of radiographic union. 6). Medial humeral epicondyle fractures are one of the most common injuries in childhood and often require surgery [1, 2].Long-term sequelae may include non-union, mal-union, instability, nerve injury, growth arrest, deformity and loss of function [1, 3].There are currently no standardised outcome measures to assess progress after an elbow injury in a child. With the rise in youth sports participation, the ideal treatment of these injuries is especially important in this high demand patient population. Background . The transverse ligament does not contribute significantly to valgus stability of the elbow.7,8,12 Finally, the ulnar nerve lies posterior to the medial epicondyle as it courses distally toward the flexor carpi ulnaris muscle belly. Fragmentation or multicentric ossification may be a normal variant and contralateral elbow films (especially bilateral external oblique radiographs) may be useful for comparison.9 The valgus gravity stress view of the elbow may be useful in assessing fracture displacement and elbow joint stability but is rarely tolerated in the setting of an acute injury.8,12 This view may show widening of the medial joint space or further displacement of the medial epicondyle. Medial Epicondylar Fractures are the third most common fracture seen in children and are usually seen in boys between the age of 9 and 14. Falls account for most of these fractures [ 2 ].
