What are the main 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 dorsal extrinsic ligaments wrist?

Two extrinsic capsular ligaments at the dorsal aspect of the wrist span the radiocarpal and midcarpal joints, the DRCL and DICL (Fig 6).

What is Puboprostatic ligament?

Puboprostatic ligaments hold and stabilize the prostate against the pubic bone. It is believed that a pelvis with bilateral, double puboprostatic ligaments would have advantages in urogenital competence.

How many ligaments are there in wrist joint?

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.

What is the difference between intrinsic and extrinsic ligaments?

There are two general categories of ligaments: intrinsic and extrinsic. Intrinsic ligaments have their origin and insertions within the carpus, with a large area of insertion onto cartilage rather than bone and much less elastic fibers compared with extrinsic ligaments.

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.

How do you fix a scapholunate ligament?

Surgery To Remove Surgical Implants:

  1. In large and unstable ligament tears, a screw is used to repair the scaphoid and lunate bones together with a reconstruction of the ligament.
  2. Once the screw is removed, we can increase your hand therapy to include wrist motion and gentle strengthening exercises.

How do you fix a scapholunate ligament tear?

Scapholunate Ligament Tear Surgery Based on what is found, the joint may be debrided (“cleaned up”). If significant instability is found, pins may be placed to hold the bones in place and/or an incision may be made to repair or reconstruct the ligaments.
