This type of injury is common when a snowboarder braces themselves when they fall down. It is common to sprain your wrist ligaments or fracture the distal radius in the radiocarpal joint (1).

The most severe injury within the knee is tearing one of your ligaments, like the anterior cruciate ligament. These can end the season really quickly. A less severe injury is just spraining one of the ligaments (1). 

Not as common as wrist or knee injures, but can still be really painful. Dislocating your glenohumeral joint can happen by landing wrong. Sprains are also possible if you land on your glenohumeral joint (1).

One of the most severe injury locations is your head. It can be really easy to hit your head hard on the ground if you fall. The best way to prevent this is always wearing your helmet and staying in control of your board (1).
