Lunate and Perilunar Dislocations.
In his treatise on joint injuries Astley Cooper (1832) included only one example of carpal dislocation. Speed (1950) estimated that carpal fractures and dislocations comprised oneeighth of injuries about the wrist. Although they are so common carpal dislocations are often unrecognised or mismanaged (Watson-Jones 1946, Cave 1958, McLaughlin 1959, Wade 1960). There is still disagreement about the...
متن کاملCarpal 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...
متن کاملImage diagnosis: Perilunate and lunate dislocations.
Perilunate Dislocation Anterior-posterior (AP) view (Figure 1) demonstrates the distal and proximal carpal rows overlapping, as well as a complete radial styloid fracture. Lateral view (Figures 2 and 3) demonstrates dorsal dislocation of the capitate, whereas the lunate remains articulated with the radius. More often seen in young men in their teens to twenties, rather than children or the elde...
متن کاملIn brief: Mayfield et al. Classification: carpal dislocations and progressive perilunar instability.
According to Melsom and Leslie, the earliest description of perilunate dislocation was by Malgaigne in 1855, before the advent of radiography [7]. It later was described by Cousins, Destot, de Quervain, and others [7]. According to Melsom and Leslie [7] Tavernier reported the first series in 1906. Many years later, in 1968, the concept of the proximal row as an intercalated segment was describe...
متن کاملLunate 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.
