Perilunate And Lunäre Dislocations

A perilunate dislocation is a disturbance of the normal relationship between the lunate and the capitate. A lunäre dislocation is the separation of both the lunate Capitatum as well as the radius.

Perilunate and lunäre dislocations occur when large force is applied to an over-stretched wrist. They result usually from a fall on an outstretched hand, or occur in a motor vehicle collision. Perilunate dislocations are five times more likely than lunäre.

Perilunate and lunäre dislocations occur when large force is applied to an over-stretched wrist. They result usually from a fall on an outstretched hand, or occur in a motor vehicle collision. Perilunate dislocations are five times more likely than lunäre. These dislocations cause pain, swelling and deformity in the wrist and proximal hand. When a perilunate or lunäre dislocation is not diagnosed and treated promptly, complications may occur. These include: injury of the median nerve avascular necrosis of the scaphoid or lunate and wear of the joint (scapholunate advanced collapse). Diagnostic radiographs overview images (from front to back, side, and perspective views) will be included. To avoid not to recognize the diagnosis, physicians should evaluate the relationship between the radius, lunate and capitate on a right side view. In a dislocation perilunären the capitate is not vertically aligned with lunate and radius on the side view of the wrist. Lunate and radius remain properly aligned In a lunären dislocation, lunate out of alignment is rotated in a “spilled teacup” configuration.
