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.

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.

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 ...

Figure 1. (a) Anteroposterior view of the right wrist demonstrating transradial styloid lunate dis-location. The lunate is seen overlapping the capitate, creating the classic " piece-of-pie " sign (white arrow). (b) Lateral view of the right wrist demonstrating lunate dislocation. The lunate is displaced and angulated out of the lunate fossa, producing the " spilt teacup " appearance (black arr...

a few numbers of patients admitted to the emergency department due to the lunate dislocation can cause a direct injury to the wrist ligament, which mainly occurs after wrist trauma, and often diagnosis is far from the mind. a 32 years old man due to severe pain and tenderness of the wrist started the previous day during swimming, referred to emergency department of imam reza hospital of mashhad...

Lunate and perilunate dislocations are uncommon, but they have clinical importance because complications, such as median neuropathy and avascular necrosis of the lunate, can occur. Although early diagnosis enabling early surgical treatment is crucial for preventing long-term sequelae, these dislocations are frequently missed in the initial assessment. Imaging tools, such as plain radiography, m...

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...

Complete disruption of the lunate from both dorsal and palmar ligamentous attachments caused by palmar dislocation has rarely been reported. The authors present two cases and discuss the surgical treatments performed. They conclude from these cases that the lunate is at risk for remaining avascular after such trauma, so that proximal row carpectomy should be considered as a surgical option in t...
