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...

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...

Rowan CH, Downing ND. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221041 Description Perilunate dislocations are uncommon high-energy injuries which are missed in approximately 25% of cases on initial presentation. We present the X-rays of a 25-year-old man who fell from a height of approximately 2 metres onto an extended wrist. Plain radiographs (figure 1) show classical signs of a trans-scaphoid ...

UNLABELLED Trans-scaphoid perilunate fracture-dislocation is the most common variety of fracture-dislocations of the wrist. Because of the carpal scaphoid fracture association, post-reduction stability is poor, often requiring surgery. Of the several surgical techniques used over time, percutaneous screw fixation for scaphoid fracture is currently preferred. MATERIAL AND METHODS Six cases of ...

Isolated dislocations of the navicular are rare injuries; we present our experience of six cases in which the navicular was dislocated without fracture. All patients had complex injuries, with considerable disruption of the midfoot. Five patients had open reduction and stabilisation with Kirschner wires. One developed subluxation and deformity of the midfoot because of inadequate stabilisation ...
