Bilateral perilunate dislocations: case report with review of literature and anatomic study.
A 33-year-old man suffered bilateral perilunate dislocations with concomitant rotary subluxations of the navicular treated with open reduction and internal fixation. Anatomic studies revealed a thick V-shaped volar radio-carpal ligament one portion of which tethers the lunate to the radius in a sling with the volar ulna-carpal ligament, and the other portion with a variable insertion on either the navicular waist or the capitate, which may account for the variety of the carpus injuries that have been reported.
