Wrists are the most commonly injured upper extremity joint, and 8.8% of injuries are missed, with 2% being clinically important. With 27 bones and 34 muscles, there is a significant possibility of missing a fracture. A high index of suspicion is required to prevent missing a significant injury.

Death from hyperkalemia is typically secondary to diastolic arrest or fibrillation, and common symptoms include weakness, paresthesias, and nausea/vomiting.
