Hamulus (Hamate)
The Hamulus was once known as the unicinate bone
The hook of the hamulus was known as the unciform process of the uncinate bone
Scaphoid
The Scaphoid, also known as the Navicular bone, has a recurrent blood supply. The artery enters distally and wraps around proximally. Thus, even in distal fractures you may see proximal necrosis.
Fractures of the navicular bone may be radiographically invisible. If the clinical signs are consistent with fracture, treat it as a fracture; then repeat later and look for osteoclastic remodeling.
Look at the Navicular fat pad for evidence of navicular fracture
The most commonly fractured hand bone is the scaphoid.
Lunate
The most commonly dislocated bone in the hand is the lunate
The most commonly fused bones in the hand are the lunate and triquetrum
Trapezoid and Trapezium
The trapezoid and trapezium were once known as the lesser and greater maltangular bones
The trapezium is nearer to the thumb, "the thumb swings on the trapez-ium".
