Often requires open reduction. Prognosis is good if the blood supply is intact and reduction is maintained. Intra-articular fracture consisting of a vertical fracture through the epiphysis that crosses the epiphyseal plate and leaves through a portion of the metaphysis. Frequently involves lateral condyle of humerus. Treated with anatomic reduction and internal fixation.
Prognosis is poor unless reduction is maintained.
Results from a crush injury through the epiphysis to a portion of the epiphyseal plate. Usually occurs in a joint that has only one plane of movement. Most commonly seen in the knee and ankle. Initial radiographs tend to be normal and so must suspect this fracture from the mechanism of injury. Results are poor with premature cessation of growth.
