What are the extrinsic ligaments of the wrist?
The extrinsic wrist ligaments are those that have an attachment on the carpus and pass out of the carpus and attach either to the distal radius or ulna and volar radioulnar ligament. They are divided into two major categories: dorsal (Fig 6) and palmar (Fig 7) (1,2).
How do you treat a scapholunate ligament tear?
3 Main Treatments for a Scapholunate Ligament Injury
- Immobilization of the Wrist. Immobilization with a wrist orthosis in the acute stages is a common intervention provided by a therapist in the acute stage.
- Wrist Stabilization. Wrist stabilization involves strengthening the SL “friendly” muscles.
- Proprioceptive Exercise.
Which muscle causes pronation to the scapholunate ligament?
extensor carpi ulnaris (ECU)
Salva-Coll et al 3 identified the extensor carpi ulnaris (ECU) muscle as causing scaphoid pronation especially in wrists with scapholunate advanced collapse (SLAC).
Is the ulnar collateral ligament intrinsic or extrinsic?
extrinsic
The UCL was found at the floor of the sixth extensor compartment below the ECU tendon (Fig. 6). Both, the RCL and UCL were within the joint capsule, therefore, they are classified as extrinsic wrist ligaments.
What are the volar wrist ligaments?
The volar radioulnar ligament represents a thickened peripheral margin of the disk of the triangular fibrocartilage complex. The vo- lar radioulnar ligament originates at the radius and, because it is associated with the disk, at- taches on the ulna at the styloid and fovea.
How do I strengthen my scapholunate ligament?

What is ulnar collateral ligament in wrist?
The collateral ligaments are two important ligaments supporting each side of the wrist and connecting it to the forearm. The ulnar collateral ligament (UCL) is located on the ulnar side of the wrist – originating at the ulnar styloid, the bony bump at the edge of the wrist on the side furthest from the thumb.
What do the ulnar and radial collateral ligaments do?
The radial and ulnar collateral ligaments of the wrist are true ligaments and can be seen at the floor of the first and the sixth extensor compartments, respectively, using high-resolution US. Based on their anatomic location, they most likely provide static stability to the wrist joint.
What is volar carpal ligament?
The palmar carpal ligament (also volar carpal ligament or Guyon’s Tunnel) is the thickened portion of antebrachial fascia on the anterior of the wrist. It is officially unnamed. Palmar carpal ligament.
Where is pain with scapholunate ligament?
However, scapholunate ligament pain causes more localised pain on the back of the wrist and is often secondary to a specific incident such as falling onto your hand. Whereas osteoarthritis of the wrist causes more diffuse (less localised) wrist pain and often occurs for no apparent reason.
What is ulnar collateral ligament injury?
The ulnar collateral ligament (UCL) is a ligament that runs on the inner side of the elbow to help support it when performing certain motions, such as throwing. When this ligament is torn or damaged, it can lead to pain, elbow instability and loss of function.
