Lunate dislocations are well described in the volar direction as part of the perilunate dislocation, sometimes together with fractures of the other carpal bones or distal radius, as described by the anatomical studies of Mayfield [1]. It is a result of disruption of the complex inter-carpal and radiocarpal ligaments that hold the well conforming carpus in their normal position. Given the streng...

The stability of the wrist during motion and interrelated motions depends on the capsuloligamentous integrity and the contact surface contours of the carpal bones [1]. Perilunate fracture dislocations (PLFD) are high-energy injuries, produced by wrist hyperextension. It can be palmar or dorsal. Palmar dislocation is extremely rare and result from a fall on the dorsum of the flexed wrist. This i...

Sixteen cases of dorsal transscaphoid perilunate fracture/dislocations in 15 patients were treated by open reduction and internal fixation of the scaphoid with a Herbert screw and/or Kirschner wires. All patients were male, with a mean age of 31 years. The average follow-up period was 3 years. These perilunate dislocations were transscaphoid in 13 cases, and transstyloid and transscaphoid in 3 ...
