There is acute fracture of the scaphoid waist with extensive marrow edema. On the sagittal images the lunate bone is tilted dorsally leading to dorsal intercalated segment instability (DISI)
Case Discussion
Scaphoid fracture most commonly involves the scaphoid waist with possible avascular necrosis of the proximal pole. Carpal instability is a recognized complication of scaphoid fracture with possible VISI, DISI, perilunate, lunate or mid carpal dislocation.
