[edit on Wikidata]
|
An ulna fracture is a break of the ulna bone in the forearm. They are often associated with radius fractures.[2] When the middle portion of the ulna is broken without other associated fractures, it may be called a nightstick fracture.[1]
A nightstick fracture is classically caused by being hit on the inside of the forearm.[1]
Treatment of nightstick fractures may be with splinting and early movement.[1]
Types
- Nightstick fracture is a fracture of the middle portion of the ulna without other fractures.[1]
- Distal ulna fractures typically occur along with distal radius fractures.[2]
- Monteggia fracture - a fracture of the proximal third of the ulna with the dislocation of the head of the radius
- Hume fracture - a fracture of the olecranon with an associated anterior dislocation of the radial head
