Hook of hamate fracture

Last revised by Yuranga Weerakkody on 6 Nov 2022

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 players (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

If occult on standard views, a carpal tunnel view may be of value for better assessment. CT can be considered if initial radiographs are negative. MRI is 100% sensitive and can be considered for high suspicion of injury.

This can be managed conservatively or with surgical excision or fixation depending on clinical status.
