IN A CASE OF A SPIRAL FRACTURE ON THE HUMERUS ,DO THE ULNA AND RADIUS CROSS EACH OTHER...
1 Answer | add yours
Crossing of the radius and ulna is a normal feature that allows partial rotation of the hand so rotation seen on X-ray would not be diagnostic of a humeral fracture, though ipsilateral fracture of the proximal forearm may be associated with distal fracture of the humerus. Spiral fracture of the humerus describes the nature of the fracture itself, and is usually a result of stress placed on the humerus. It is a not uncommon consequence of basketball throwing and arm wrestling (not at the same time!). The radial nerve which wraps around the humerus is often damaged and this can produce symptoms at the back of the hand.
