ABSTRACT
ABSTRACT Lunate dislocation is a circumambient disruption of the lunate bone. It is an uncommon but devastating wrist injury that can have negative effect on lifestyle with significant morbidity. This injury can go unrecognized by physicians resulting in complications including but not limited to carpal tunnel syndrome and Kienbock’s disease. We present two cases of type 4 lunate dislocation that presented within 24 hours of injury; one had fallen off a moving motorcycle while the other had been involved in a motor vehicle accident. The second developed carpal tunnel syndrome. Radiographs showed typical appearances. Both had Open Reduction with Internal Fixation (ORIF), recovered well, and had good function at the outpatient follow-up.
Key word: Lunate dislocation, Terry-Thomas sign, spilled tea-cup sign, open reduction.
