Carpal dislocation and fracture dislocation are uncommon and difficult to treat. Early diagnosis and treatment of such injuries are necessary to prevent progressive carpal instability and traumatic arthritis. Perilunate fracture dislocation is a combination of ligamentous and osseous injuries that involve the 'greater arc' of the perilunate. Despite being severe, these injuries often go unrecognised in the emergency department, leading to delayed diagnosis and treatment. We present a case of greater arc injury of the right wrist with fractures of the lunate and ulnar styloid without perilunate dislocation. This pattern of injury cannot be classified in the available literature on greater arc injury.

Isolated dislocation of the scaphoid is very rare. A 45-year-old male, industrial worker reported two and half months after injury with wrist pain and swelling on the dorsum of left wrist. He was diagnosed as neglected dorsal dislocation of scaphoid. Proximal row carpectomy with capsular interposition was done stabilizing the distal carpus on the radius using Kirschner wires. At 12 months follow-up the patient had good wrist function and was satisfied with the outcome of the treatment. We hereby report this neglected dorsal dislocation of scaphoid in view of rarity and discuss the various options for management. [ABSTRACT FROM AUTHOR]
