A fracture of the ulna affects the forearm bone on the same side as your pinky. This bone narrows toward the hand and widens toward the elbow, actually forming the elbow “point.” Fractures of this bone can occur at any point along the bone, and have different descriptors depending on the location. Fractures near the wrist are distal fractures. Those in the middle of the bone or near the elbow are proximal fractures.
