Scaphoid fracture with proximal pole infarct/osteonecrosis and SLAC with DISI

A displaced fracture involving the scaphoid waist with marked sclerosis and volume loss of the proximal pole of scaphoid bone due to secondary osteonecrosis.

 Scapholunate joint subluxation with evidence of dorsal tilt of the lunate bone – dorsal intercalated segmental instability (DISI).

 Resultant proximal recession of the capitate bone due to the scapholunate gap – likely suggestive of scapholunate advanced collapse ( SLAC)

 Subchondral small undisplaced fractures involving the lunate, triquetral, capitate, hamate bones with large marrow contusion involving the hamate
