Acute scaphoidectomy and four-corner fusion for the surgical treatment of trans-scaphoid perilunate fracture dislocation with pre-existing scaphoid non-union.

This paper presents a rare case of trans-scaphoid perilunate fracture dislocation with concurrent scaphoid non-union of the left wrist following a motorcycle accident. Emergent CT identified scaphoid non-union advanced collapse and an acute scaphoidectomy, four-corner fusion, denervation and radiocarpal ligament repair was performed.
