3 point symmetry is NOT disturbed in which fracture
B i.e. Fracture radius only Weak posterior capsule may disrupt three point bony relation by promoting subluxation or dislocations of elbow. Fracture ulna on the upper end i.e. involving olecranon also disturb three point symmetry. But the radius has nothing to do with three point bony relationshipQ and so it will not disturb three point bony symmetry.
Fracture ulna only
Fracture radius only
Fracture of radius & ulna both bones of forearm
Weak posterior capsule
