Answer

Answer

The lunate is located 1 cm distal and ulnar to the Lister tubercle. Flexion of the wrist causes the lunate to become prominent. Tenderness and/or swelling over the dorsum of the lunate should increase the index of suspicion for Kienböck disease, especially when decreased range of motion secondary to pain is present. The lunotriquetral joint is palpated for tenderness, indicating a possible sprain or dislocation. An associated wrist click is often present with lunotriquetral instability. Tenderness on the radial side of the lunate may be secondary to an occult ganglion or a small scapholunate interosseous ligament tear.
