چکیده

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 close observation with both arthroscopy and fluoroscopy, we decided not to conduct open reduction and internal fixation for the lunate. Partial avascular necrosis of the lunate appeared gradually in follow-up.

[Palmar scaphoid dislocation associated with dorsal perilunate dislocation. A case report and review of the literature].

Most carpal dislocations occur in the lunate bone or around it (perilunate). An isolated dislocation of the carpal scaphoid is a rare injury. We report a case of a palmar scaphoid dislocation combined with a dorsal perilunate dislocation, which was treated with open reduction, fixed with two Kirschner wires and ligament repair, with a good result.

Open perilunate injury with lunate revascularization after complete ligamentous avulsion

Perilunate dislocations are a devastating injury to the carpus that carry a guarded long-term prognosis. Mayfield type 4 perilunate dislocations are rare, high-energy injuries that carry a risk for avascular necrosis (AVN) of the lunate. When AVN ensues and the carpus collapses, primary treatment with a proximal row carpectomy or arthrodesis has been advocated. This case reports a successful cl...

Delayed Avascular Necrosis and Fragmentation of the Lunate Following Perilunate Dislocation.

Perilunate and perilunate fracture dislocations are high-energy injuries with the wrist loaded in extension, ulnar deviation, and intercarpal supination. The force vector travels from a radial to a ulnar direction and can result in complex carpal instability. The diagnosis is often delayed, which can result in suboptimal outcomes. Nonoperative management can produce inferior results, with patie...

Management of Acute Trans Scaphoid Peri-Lunate Fracture Dislocation by Closed Reduction and Percutaneous Fixation

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...

Classification and management of carpal dislocations.

A classification and plan of management for carpal dislocations are presented, based upon the following basic premises: perilunate and lunate dislocations are different stages of the same injury and are therefore managed identically; displacement may be either dorsal or volar; anatomic restoration of the 3 key elements (scaphoid, lunate, and capitate) is essential. Following initial closed redu...
