The ulnar collateral ligament of the thumb runs along the ulnar side of the metacarpo-phalangeal joint of the thumb. The ulnar collateral ligament is an important stabilizer of the thumb. It is on the radial side of the wrist, but on the ulnar side of the thumb. It should not be confused with the ulnar collateral ligament of wrist joint.
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. [1] A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx.
The ulnar collateral ligament (internal lateral ligament, ulnar carpal collateral ligament or ulnar collateral ligament of the wrist joint) is a rounded cord, attached above to the end of the styloid process of the ulna, and dividing below into two fasciculi, one of which is attached to the medial side of the triquetral bone, the other to the pisiform and flexor retinaculum.
The triquetral bone (/ t r aɪ ˈ k w ɛ t r əl,-ˈ k w iː-/; also called triquetrum, pyramidal, three-faced, and formerly cuneiform bone) is located in the wrist on the medial side of the proximal row of the carpus between the lunate and pisiform bones. It is on the ulnar side of the hand, but does not directly articulate with the ulna.
The pisiform bone is a small bone found in the proximal row of the wrist . It is situated where the ulna joins the wrist, within the tendon of the flexor carpi ulnaris muscle. [1]: 199, 205 It only has one side that acts as a joint, articulating with the triquetral bone. It is on a plane anterior to the other carpal bones and is spheroidal in form.
Fingers and wrists - Wrist sprains commonly occur, especially during a fall on an outstretched hand. Gamekeeper's thumb (Skier's thumb) - forceful grabbing that leads to an injury to the ulnar collateral ligament (UCL) at the metacarpophalangeal (MCP) joint of the thumb, historically found in Scottish gamekeepers [20] Spine
A Stener lesion is a type of traumatic injury to the thumb. It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx. No longer in contact with its insertion site, the UCL cannot spontaneously ...
