Plain radiographs show a proximal humerus fracture that occured through the epiphyseal plate causing slipped proximal humeral epiphysis medially and inferiorly, like ice cream from a cone. So, it is considered a Salter-Harris type I fracture. See similar case (rID-170191).

Proximal humeral Salter-Harris type II fracture is most frequent after 12 years than type I fractures. Classically, type II features involve fracture of medial part of proximal humeral metaphysis. See case (rID-95758).

Generally, proximal humeral physeal injuries are treated non-operatively. Patients older than 11 years with significant displacement usually require closed reduction with percutaneous screws or wires.

There is also non-fusion of the coracoid ossification center, which completely fuses by 16-17 years of age, which mimics a fractured base of coracoid process.
