Trans-scaphoid perilunate fracture dislocations, which account for more than half of total cases injuries, are common in young patients and occur as a result high-energy improper management can impair wrist alignment function. Understanding the related anatomy pathomechanics may help surgeons evaluate diagnose patients. Early operation to reduce fix injuries should be considered achieve optimal...

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...

The wrist represents a complex anatomic region in the human extremity and a highly functional and intricate structural joint. Most perilunate injuries result from a staged disruption of the ligamentous structures. Forces may be directed through the carpal bones themselves resulting in a fracture. Early anatomic reduction of any carpal malalignment is of the utmost importance. Unfortunately, eve...

THE PATIENT A 37-year-old man injured his right wrist in a motor vehicle collision. In the emergency department he had severe wrist pain and median nerve paresthesia. Wrist radiographs identified a dorsal perilunate dislocation (PLD) with the carpus dislocated dorsally and the lunate tilted volar but still located in the lunate fossa. Post-reduction computed tomography scan confirmed no fractures.

A rare case of trans-radial styloid, trans-scaphoid, trans-triquetral perilunate dislocation is described. The injury was treated by reduction and internal fixation using a Herbert screw and Kirschner wire. A good functional result was achieved. A review of the literature illustrates that early surgery is recommended. Alternative surgical approaches are discussed.

OBJECTIVE In this study, eighteen patients who have had perilunate injury with dislocation or fracture, were evaluated and the patho-mechanics and surgical treatment were studied. SUBJECTS AND METHODS According to the Green and O'Brien's classification, type 1 injury occurred in one patient, type 2 in nine, type 4A in five, type 4C in one and type 4D in one. The other one case could not be cl...
