The Elbow is one of
the major functional joints in the human body. It is second in dislocations
only to the shoulder joint. It is described as a hinge joint. This joint
is designed to move in flexion (the arm is
bent) and extension (the arm is straight).
The elbow is kept in this plane by ligaments, tendons, muscles, and placement
of bones which all act as stabilizers to this joint.
. The rest of the
joint is composed of the ligament complexes. These ligaments provide up
to 50% of the elbow joint stability. These ligaments can be divided into
two complexes:
- Lateral ligament
complex (located on the outer side of the elbow)
- Lateral
collateral ligament.
- Radial
collateral ligament
- Annular
ligament
There are three main
bones that make up the elbow. These three are the humerus
(arm bone), the radius, and the ulna
(these two bones make up the forearm)
2.Medial collateral
ligament complex ( located on the inner side of the elbow) = the
UCL(ulnar collateral ligament
- Anterior
band (most important in terms of injury and repair)
- Posterior
band
- Transverse
ligament
