Clinically Relevant Anatomy
[edit | edit source]
The hamate bone is a triangular bone located in the distal carpal row and is situated on the ulnar side. He is composed of a body and a hook. Hamate fractures constituted about 2% of all carpal fractures.[1][2] They are classified as type I fractures involving the hook and type II fractures involving the body. Type I fractures are more common than type II fractures.Cite error: Invalid <ref> tag; name cannot be a simple integer. Use a descriptive title
The hamate is bordered proximally by the pisiform and the lunate in the proximal carpal row, radially by the capitate, and distally by the bases of the fourth and fifth metacarpals.Cite error: Invalid <ref> tag; name cannot be a simple integer. Use a descriptive title
The Guyon canal carries the ulnar artery and nerve, for this reason hook fractures should suggest a high probability of ulnar artery and nerve damage.
