volar lunate dislocation is the fourth and last stage of perilunate dislocation. it is an uncommon injury of the wrist and its bilateral occurrence is so rare that only one case has been reported in the literature. we are presenting the second case of this kind of wrist injury, its treatment and outcome. keywords : lunate bone, perilunate, volar plate, bilateral, dislocation.

A 24-year-old male presented to the ED after a fall of approximately 25 feet from a rooftop. As he landed, he attempted to break his fall with an outstretched hand. His injuries were limited to right-sided acetabular and pubic rami fractures, and the wrist fracture-dislocation shown here (Figs. 1, 2, 3, 4). Perilunate dislocations are often accompanied by scaphoid fractures due to the stresses ...

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 ...

Perilunate dislocations and perilunate fracture-dislocations usually result from high-energy traumatic injuries to the wrist and are associated with a characteristic spectrum of bony and ligamentous damage. Radiographic evaluation of the wrist reveals loss of normal radiocarpal and intercarpal colinearity and bony insult, which may be overlooked at the initial presentation. Prompt recognition i...

BACKGROUND Transscaphoid perilunate fracture dislocation is a rare injury and can be easily missed at the initial treatment. Once ignored, late reduction is not possible and needs extensive dissection. An alternative treatment such as proximal row carpectomy may be required for neglected injuries, but surgical outcome is not as good as that of an early reduction. We aim to present an alternativ...

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...

conclusions this study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors. background distal radius radiographic indices may play a role as risk factors in pathogenesis of kienbock’s disease, scaphoid fracture and non:union:. perilunate fracture dislocations a...

INTRODUCTION Perilunate and lunate dislocations are uncommon high energy injuries and have extensive soft tissue, cartilaginous and bony damage. The most common pattern is trans-scaphoid perilunate fracture dislocation which constitutes approximately 50% of these injuries. Unusual injury pattern like Scaphocapitate syndrome can occur with fracture through scaphoid waist and capitate that rotate...

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...
