Carpal fractures account for approximately 5% of all fractures and 18 percent of hand fractures, and scaphoid fractures are the most common carpal fracture. Scaphoid fractures account for 10% of all hand fractures and 60-70% of all carpal fractures. Scaphoid fractures are among the most common upper extremity injuries. They frequently occur following a fall onto an outstretched hand. Plain radiographs taken soon after the injury may not reveal a fracture, but the clinician should assume one is present until definitive proof otherwise is obtained.
