What are the dorsal radiocarpal ligaments?
The dorsal radiocarpal ligament forms a part of the dorsal radiocarpal joint capsule and connects the dorsal radial rim with the lunate and triquetral bone. It is a broad and trapezoid like shaped ligament, courses in an oblique orientation and forms a toppled and horizontally oriented V-shape 1-4.
Where is the dorsal wrist ligament attached?
The DRC ligament was consistently found to originate from the dorsal margin of the distal radius and extended ulnar obliquely and distally. Its radial fibers attached to the lunate and lunotriquetral interosseous ligament. The DRC ligament then inserted onto the dorsal tubercle of the triquetrum.
What are the ligaments of the wrist?
Wrist Ligaments The Ulnocarpal and radioulnar ligaments are two sets of ligaments that provide the main support for the wrist. The scapholunate interosseous ligament and the lunotriquetral interosseous ligament provide stability to the proximal carpal row.
What are the three ligaments of the wrist?
Radial and ulnar collateral ligaments – a pair of ligaments which bind the bones of the wrist and provide stability. Volar radiocarpal ligaments – a complex web of ligaments that support the palm side of the wrist. Dorsal radiocarpal ligaments – ligaments that support the back of the wrist.
Where is dorsal radiocarpal ligament?

What is dorsal wrist pain?
Dorsal Wrist Impingement Syndrome. Dorsal wrist impingement syndrome is a wrist condition that causes pain along the back (dorsal) side of the wrist. A pinching discomfort, or pain, is felt when the wrist is bent backwards (extended).
What causes dorsal wrist pain?
There are several conditions that can cause this pain, such as a small (occult) ganglion cyst, tendinitis, ligament injuries, or something called dorsal wrist impingement syndrome.
Where is the radioulnar ligament?
The palmar radioulnar ligament (volar radioulnar ligament, anterior radioulnar ligament) is a narrow band of fibers extending from the anterior margin of the ulnar notch of the radius to the front of the head of the ulna. It is sometimes abbreviated PRUL.
What is the most commonly injured ligament in the wrist?
Two of the common ones are the scapholunate ligament, in the middle of the wrist between the scaphoid and lunate bones (Figure 2), and the TFCC (triangular fibrocartilage complex) on the outside of the wrist. Sometimes, a sprained wrist can pull off a tiny piece of bone. This is called an avulsion fracture.
How many main ligaments does the wrist contain?
The four ligaments responsible for maintaining the stability of the joint are the palmar and dorsal radiocarpal ligaments and the ulnar and radial collateral ligaments.
How do you fix dorsal wrist pain?
Some patients will improve with rest, activity modification, splints, or anti-inflammatories. In recalcitrant cases, an MRI is useful to gain more information. However, while an MRI may show a ganglion, tendinitis or ligament tear, patients with dorsal wrist impingement syndrome typically have a normal MRI.
What helps dorsal wrist pain?
If one has chronic pain, there is a stepwise approach to treatment.
- Initially, we start with splints.
- Specialized Dorsal Impaction Hand Therapy Programs.
- Anti-inflammatory creams and medications.
- Cortisone injections.
- Surgery, however, this is a last resort used for salvage or desperate situations.
What is volar radioulnar ligament?
The palmar radioulnar ligament (volar radioulnar ligament, anterior radioulnar ligament) is a narrow band of fibers extending from the anterior margin of the ulnar notch of the radius to the front of the head of the ulna.
How do I know if I have a torn ligament in my wrist?
If you have any of the following symptoms, you may have a torn ligament in the wrist: Pain when bending the wrist backward. Inability to move your wrist all the way around. Bruising.
What is the top of your wrist called?
The carpal bones are bound in two groups of four bones:
- the pisiform, triquetrum, lunate and scaphoid on the upper end of the wrist.
- the hamate, capitate, trapezoid and trapezium on the lower side of the hand.
Why does the top of my wrist hurt?
Summary. Wrist pain can come from injuries like sprains, tendonitis, and fracture. It can also come from conditions such as arthritis and carpal tunnel syndrome. Diagnosing wrist pain may involve a physical exam, bloodwork, imaging, and special tests based on your provider’s suspicions.
How long does dorsal wrist impingement take to heal?
Surgery May Be Required This surgery helps repair the muscles and eliminates pain. Afterward, you’ll need to perform range of motion exercises regularly to promote strength in your wrists. After surgery, it often takes six weeks to three months for your wrist to be back to its normal strength.
How do you treat a dorsal wrist impingement?
There is no way to repair the damage once it has occurred. Prevention is the main treatment. Avoidance of activities that bend the wrist past 35-degrees. If you’re doing an activity where your wrist may be forced back, consider a splint that holds your wrist in a neutral position, such as this one here.
