The pediatric vs. the adolescent elbow. Some insight into age-specific treatment.

Almost 20 % of all long bone fractures in childhood and adolescents involve the elbow region. Physicians dealing with pediatric trauma cases on a regular basis must be familiar with the specific radiologic features of the elbow at every developmental stage. This includes the shape and the appearance of elbow ossification centers, and knowledge of age-specific injury patterns. In young children, lateral condyle and supracondylar fractures of the distal humerus are most common. Radial neck fractures, Monteggia's lesion and olecranon fractures appear in every age during growth. Bicondylar fractures of the distal humerus, capitellar fractures and radial head fractures almost solely occur after the tenth year. Treatment options depend on fracture type, age and demands and vary from immobilization to closed reduction and open reduction including internal fixation with different types of materials. Special circumstances to influence the treatment regimen in every single injury entity are discussed. Additionally, the most common malformations and nontraumatic diseases of the elbow region are mentioned.
