Ulnar fractures frequently occur in motorcycle crashes.
The ulna is a thin bone located on the little finger side of the forearm. It acts as a bone that helps supination and pronation (twisting) of the forearm. Technically, a fracture can occur at any point along the bone but it is mostly fractured along with the radius after a fall on the outstretched hand. It can also be fractures along its length when it is struck by an object directly.
Themain symptoms of an ulnar fracture are pain, swelling, bruising and a deformity along the area of the fracture. In some cases, the fracture can be associated with a dislocation of the ulna from the elbow, which leads to pain and immobility of the elbow. This is called as a Monteggia Fracture.
