Hook of hamate fracture

Dr Yuranga Weerakkody and Dr Henry Knipe et al.

Hook of hamate fractures (also sometimes termed type 1 hamate fractures) are rare. They are a form of hamate fractures and occur from the hamate fracturing after blunt trauma, falls, and in sports player (e.g. golf, baseball, racquet sports) from a direct blow while swinging. Stress fractures have also been reported. 

It may result in Guyon's canal syndrome

Radiographic assessment

If occult on standard views, a carpal tunnel view may be of value for better assessment.
