Complete Anterior Scaphoid Expulsion in Transscaphoid-Lunate Dislocation in an Adult Male After Fall

Wrist injuries involving the lunate occur most often in youths involved in high-energy traumas that cause a fall on an outstretched hand (1). Seven percent of all carpus injuries involve the lunate, of which only 3% are classified as volar lunate dislocations (1,2). Because of this injury's rarity, they are often misdiagnosed and may be missed in 25% of cases (3). This can lead to further damage, such as median nerve injury, carpal instability, complex regional syndrome, carpal tunnel syndrome, and post-traumatic arthritis (2,4).
