Perilunate Dislocation

چکیده
Figure 1. Radiograph demonstration of a perilunate dislocation: The lunate maintains its normal articulation with the radius, whereas the capitated articular surface is dislocated from the lunate dorsally. Figure 2. Diagrammatic representation of the 3 carpal arcs of Gilula's lines. The first arc is a smooth curve outlining the proximal convexities of the scaphoid, lunate, and triquetrum. The second arc traces the distal concave surfaces of the same bones, and the third arc follows the main proximal curvatures of the capitate and hamate. Copyright by Pinterest.
