What is another name for the distal radius?
25-2). The distal radius articulates with the scaphoid and lunate; and this is called the radiocarpal joint. It is a biaxial ellipsoid joint, meaning it has two axes of motion: (wrist) flexion/extension and radial/ulnar deviation.

What is the hamate?
The hamate is one of the carpal bones that form the carpal arch, wherein the carpal tunnel is situated . It forms part of the ulnar border of the carpal tunnel. It also serves as an attachment for multiple structures such as the transverse carpal ligament (flexor retinaculum). The pisohamate ligament connects the pisiform to the hamate and this forms an osseofibrous tunnel that is called the ulnar canal (Guyon canal). The ulnar nerve passes through this canal between the pisiform and hook of hamate.
What is the function of the hamate?
It forms part of the ulnar border of the carpal tunnel. It also serves as an attachment for multiple structures such as the transverse carpal ligament ( flexor retinaculum).
What metacarpals does the Hamate articulate?
The hamate articulates with the 4th and 5th metacarpals, lunate, triquetrum and capitate.
What muscle attaches to the pisiform?
Flexor carpi ulnaris - This is a muscle in the anterior compartment of the forearm. It attaches distally to the pisiform, hook of hamate and 5th metacarpal. It allows wrist flexion and adduction.
Where is the hamate bone?
The hamate bone is one of eight carpal bones that forms part of the wrist joint. The word hamate is derived from the Latin word hamulus which means “a little hook”. It is a wedge-shaped bone with a hook-like process that can be found in the medial side of the wrist. Sometimes it is also called unciform bone.
Which muscle is located in the anterior compartment of the forearm?
Flexor carpi ulnaris - This is a muscle in the anterior compartment of the forearm. It attaches distally to the pisiform, hook of hamate and 5th metacarpal. It allows wrist flexion and adduction. Flexor digiti minimi brevis - This is an intrinsic muscle of the hand.
Where is the hook of hamate located?
It is situated in the distal row of carpal bones on the medial side of the wrist. It has multiple articulation surfaces. The hook of hamate can be palpated on the medial side of the wrist inferior and laterally to the pisiform.
What causes a hook of hamate fracture?
A hook of hamate fracture in the wrist can occur from swinging a golf club, tennis racket or baseball bat, particularly if it suddenly hits an immovable object.
What is a hook of hamate?
Hook of hamate fracture is a fracture of a hook shaped protrusion on the hamate bone, which is one of the small carpal bones in the wrist. It may occur when swinging a golf club or tennis racket against an immovable object. Here we explain the symptoms, causes and treatment for a hook of hamate fracture.
What are the symptoms of a fractured hook of hamate?
Symptoms. Symptoms of a fracture of the hook of hamate usually follow a traumatic incident and include: Wrist pain on the little finger (Ulna) side of the wrist. You will have reduced grip strength.
What happens when you hit your wrist?
The sudden force going through your wrist may cause a break of the hamate bone. Being struck from behind by a car when cycling may cause the handlebars to be forced upwards violently, therefore having a similar effect as the Golf club example.
