Ejection of the proximal scaphoid in a trans-scaphoid perilunate fracture dislocation. A case report.

Trans-scaphoid perilunate fracture dislocations are difficult injuries to treat. Described herein is the unusual case of a trans-scaphoid perilunate fracture dislocation in which the proximal scaphoid fragment was ejected into the volar aspect of the distal forearm. The significant displacement of the proximal fragment represented complete devascularization of this piece. This unique fracture raised difficult management issues in the treatment of this injury. A primary proximal row carpectomy was performed, with a successful clinical result.
