Acute sprains of the carpus can produce swelling and pain that result in significant lameness, but this should resolve with rest, anti-inflammatory medications and/or hot/cold packing, over a few days to a week. Also, there should be no instability.
Fracture of the bones within or around the carpus will also produce swelling and pain, but this does not resolve and may produce instability or "crunchiness" (crepitus) on manipulation of the fracture. There is normally no hyperextension of the carpus. Plain X-rays should define these kinds of fracture.
Damage to the medial or lateral collateral ligaments, the ligaments that run down the sides of the carpus, will produce sudden onset of pain or swelling, but instability, if present, will be produced in a side-to-side plane, not front-to-back as with a hyperextension injury. Stress radiographs in a side-to-side direction will help define a damaged medial or lateral collateral ligament.
