Prognosis is excellent because the blood supply is almost always intact. Intra-articular fracture that extends from the joint surface across the epiphysis to the epiphyseal plate and out to the periphery. Commonly involves the lower tibial epiphysis. Caused by an intra-articular shearing force. 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.
