Chronic volar distal radioulnar joint instability: joint capsular plication to restore function
3280 Hospital Drive NW Calgary AB T2N 4Z6 Conclusion:Joint capsular plication for DRUJ has not yet been described in the litera- ture. It is less elaborate in that it does not require a tendon graft with bone tunnels....

volar displacent of a dislocation of the distal radius

* lunate dislocates posteriorly
* other carpal bones remain in alignment
less common than perilunate dislocation

* lunate remains aligned with radius
* capitate dislocates (usually posteriorly)
* more common than lunate dislocation (radial-lunate ligaments stronger than lunate-capitate ligaments)
* associated with scaphoid fractures (75%) = "transscaphoid perilunate dislocation"

Perilunate dislocations and perilunate fracture dislocations are the most devastating closed injuries of the wrist.1, 2, 3 They are often missed on initial evaluation, leading to devastating complications. These injuries occur as the final stage of a spectrum of injuries progressing around the wrist in a radial-to-ulnar direction. In the...

Transradial styloid perilunate fracture-dislocation represents greater arc (Gilula's arcs) injury.
Greater arc injuries may be divided into following stages based on their severity:
Stage I: transradial styloid perilunate fracture-dislocation;
Stage II: transscaphoid perilunate fracture-dislocation;
Stage III: transscaphoid, transcapitate perilunate fracture-dislocation;
Stage IV: transscaphoid (or radial styloid), transcapitate, transtriquetral perilunate fracture-dislocation; and
Stage V: complete palmar lunate...

Perilunate dislocations, lunate dislocations and perilunate fracture dislocations are rare injuries comprising of less than 10% of all wrist injuries. Volar peri-lunate dislocations (VPLDs) account for less than 3% of perilunate dislocations. These severe carpal injuries occur after high-energy trauma to the wrist and falls on the outstretched hand. We...

Carpal dislocations represent a continuum of wrist injury that can lead to lunate or perilunate dislocation. The lunate cup commonly is directed in a volar direction in dislocation because of the mechanism of the injury. Perilunate dislocations result from dislocation of the distal carpal row. The capitate normally rests within...

Wrist injuries are common among athletes. Emergency physicians or family practitioners frequently perform the initial evaluation of wrist injuries and determine the initial treatment. Recognizing wrist dislocations early and properly referring patients with wrist dislocations can prevent complications, including prolonged pain and discomfort, surgery, and lost time from sports participation.
