Lunate and perilunate dislocations are uncommon, but they have clinical importance because complications, such as median neuropathy and avascular necrosis of the lunate, can occur. Although early diagnosis enabling early surgical treatment is crucial for preventing long-term sequelae, these dislocations are frequently missed in the initial assessment. Imaging tools, such as plain radiography, m...

We report the case of a 21-year-old man who injured his right hand in a fall from his motorbike, causing a trans-scaphoid perilunate fracture-dislocation associated with vertical fracture of the pyramid (A and B). On day 2, patient underwent a bloody reduction (C) of disorganized carpal bones with osteosynthesis of scaphoid and pyramid (D). Peri-lunate fracture-dislocation is a rare injury cons...

dislocations are common wrist injuries. Perilunate injuries, as described by Mayfield,1 are most common and perhaps best understood. Disruption of the carpal ligaments or fractures of the carpal bones can occur in almost any combination. The injury occurs as a result of extreme hyperextension, ulnar deviation, and internal carpal supination. As the deforming force increases, the ligaments and b...
