Anatomy of the thumb metacarpophalangeal ulnar and radial collateral ligaments
. J Hand Surg Am.
The ligament that supports the outside of the elbow is the radial collateral ligament
. It holds the radius to the distal end of the humerus.
The observation that, radial collateral ligament
does not give collagen fibers in the location to adhere the bone, made us believe that, the weakest part of the anular ligament of radii may be the closest part to the bone.
Inability to perform a chair rise test in which the patient is asked to raise his or her body from an armless chair using his or her hands is another positive sign indicating a tear of the radial collateral ligament
. The history of presentation, signs and symptoms may overlap a diagnosis of lateral epicondylitis, posterior lateral plica syndrome or lateral epicondyle stress fracture making MSKUS a key tool for diagnosis and treatment of this disorder.
The radial collateral ligament
is elevated as a longitudinal osteoperiosteal sleeve off of the ablated thumb.
The lateral collateral ligamentous complex consists of the radial collateral ligament
, the lateral ulnar collateral ligament, the accessory lateral collateral ligament, and the annular ligament.
It is comprised of the radial collateral ligament
, the lateral ulnar collateral ligament, the accessory collateral ligament, and the annular ligament.
Overly aggressive surgical procedures, such as common extensor tendon release or radial head resection, can also lead to radial collateral ligament
The lateral collateral ligament (LCL) complex consists of the annular ligament, the radial collateral ligament
, the lateral ulnar collateral ligament (LUCL), and a variably present accessory LCL.
