Understanding the normal ossification pattern of the elbow and proximal radius is essential for correct diagnosis. The presence of associated injuries or dislocation is also noted.

Proximal/ head fractures are classified according to the Salter-Harris scheme. There are several classifications described, most taking into consideration the amount of displacement (angulation) and translation of the fragment. Classification is based on plain radiographs. Typically, radiographs are the only imaging studies required. A careful neurovascular examination is important, particularly the assessment of posterior interosseous nerve function. Patients will exhibit pain and limited range of motion. There may be lateral elbow swelling and ecchymosis. Around 30-50% are associated with other injuries such as ulna, olecranon and distal humerus fractures, elbow dislocation and collateral ligament injury. (Novoth, 2002) Most occur between ages 8 and 12, with equal distribution between males and females. The incidence of radial neck fracture is around 1% of all pediatric fractures and between 5-10% of all pediatric elbow fractures. While most fractures are metaphyseal, physeal fractures can occur and place the radial head at high risk of avascular necrosis (AVN). They are often associated with other injuries including olecranon fractures, elbow dislocations, medial epicondyle fractures and ulna shaft fractures. Proximal radius fractures include fractures of the proximal portion of the radius including the radial neck and head. Treatment should follow a stepwise approach.The most common complication is stiffness or loss of motion.Associated injuries are common and should be ruled-out.Study Guide Proximal Radius (Radial Neck) Fractures Key Points:
