Fracture scaphoid waist associated with small sized proximal pole exhibiting low T1 signal and bright STIR signal denoting avascular necrosis. There is cystic changes of the lunate and scaphoid with thinning of radiocarpal articular cartilage suggesting osteoarthritic changes. Minimal joint effusion some of them crossed the triangular fibrocartilage.

Case Discussion

Scaphoid fracture usually occurs due to falling on outstretched hand that lead to hyperextension of the wrist joint. The most common site of fracture is the waist which is also associated with increased risk of avascular necrosis of the proximal pole as the blood supply of the scaphoid traverses from distal to proximal.
