Lunate and Perilunar Dislocations.

Carpal dislocations: pathomechanics and progressive perilunar instability.

The pathomechanics, ligamentous damage, and degree of carpal instability in perilunate and lunate dislocations were analyzed by experimentally loading 32 cadaver wrists to failure. Thirteen perilunate and two lunate dislocations were produced. The mechanism of injury was extension, ulnar deviation, and intercarpal supination. These dislocations occurred in a sequential fashion due to progressiv...

Bilateral perilunar dislocation of the carpus; report of a case.

Isolated Dorsal Dislocation of the Lunate

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...

Lunate dislocation.

Carpal dislocations are wrist injuries and Lunate dislocation is its severe form. Lunate and perilunate dislocations are uncommon. These injuries have significant clinical impact on the patient but are easily missed and lead to potentially devastating effect if mismanaged. This case report outlines the important clinical aspects and management of Lunate dislocation.

Partial Necrosis of the Lunate after a Translunate Palmar Perilunate Fracture Dislocation

We present an extreme rare case of traumatic partial avascular necrosis of the lunate after palmar perilunate dislocation with lunate fracture. A 32-year-old female was injured by motorcycle accident with palmar perilunate fracture dislocation and lunate fracture. Scapholunate and lunotriquetrum dislocations were reduced and fixed temporarily. The torn dorsal ligament was repaired. Considering ...
