Diagnosis

Complete articular fracture, simple articular, simple metaphyseal 

print

These are complete articular fractures with simple components to both articular and metaphyseal areas.
It must be remembered that approximately 1/3 of patients with a sagittal split will additionally have a frontal plane fracture (Hoffa fracture; making it a multifragmentary articular injury)

Complete articular fractures of the distal femur are either the result of high energy trauma in the younger patient, or simple falls in the elderly, osteoporotic patient.

A simple articular split with a simple metaphyseal component is most commonly seen in the young individual and it is rare in the osteoporotic elderly patient, in whom there is generally significant comminution. The patella may commonly obscure a minimally displaced intraarticular split. For this reason, if there is ever a question of an intraarticular split, oblique radiographs or a CT scan is helpful.
