There is also another important ligament called the annular ligament that wraps around the radial head and holds it tight against the ulna. If they do not heal correctly the elbow can be too loose, or unstable. They can be torn when there is an injury to or dislocation of the elbow. These ligaments are the main source of stability for the elbow. Together these two ligaments connect the humerus to the ulna and keep it tightly in place as it slides through the groove at the end of the humerus and bends the elbow. The MCL of the elbow is on the inside edge, and the LCL is on the outside edge. In the elbow, two of the most important ligaments are the medial collateral ligament (MCL) and the lateral collateral ligament (LCL). A joint capsule is a watertight sac that surrounds a joint and contains lubricating fluid called synovial fluid. The ligaments around a joint usually combine together to form a joint capsule. Ligaments are soft tissue structures that connect bones to bones and are the main anatomical feature that creates stability in a joint. There are several important ligaments in the elbow. In the elbow, articular cartilage covers the end of the humerus, the end of the radius, and the end of the ulna. It is slippery, which allows the joint surfaces to slide against one another without causing any damage.

Articular cartilage is white, shiny, and has a rubbery consistency. It is a bit thinner in joints such as the elbow, which don't support weight. Articular cartilage can be up to one-quarter of an inch thick in the large, weight-bearing joints. The edges are also smooth where it glides against the ulna.Īrticular cartilage is the material that covers the ends of the bones in a joint. As a result, the end of the radius at the elbow is shaped like a smooth knob with a cup at the end to fit on the end of the humerus. The joint is even more complex because the radius has to slide against the ulna as it rotates as well. At the same time, it has to slide against the end of the humerus as the elbow bends and straightens. This joint is complicated because the radius has to rotate so that you can turn your hand palm up and palm down. Most people don’t realize that there is a second joint where the end of the radius (the radial head) meets the humerus. The elbow itself is essentially a hinge joint, meaning it bends and straightens like a hinge.

The bones of the elbow are the humerus (the upper arm bone), the ulna (the larger bone of the forearm, on the opposite side of the thumb), and the radius (the smaller bone of the forearm on the same side as the thumb). #testimonialslist|kind:all|display:slider|orderby:type|filter_utags_names:Elbow Pain|limit:15|heading:Hear from some of our patients who we treated for *Elbow Pain*# Anatomy what Endurance Rehabilitation and Wellness Center, PC’s approach to rehabilitation is.

These two injuries (fracture-dislocation) often occur together. The amount of force needed to cause an elbow dislocation is enough to cause a bone fracture at the same time. A partial dislocation is referred to as a subluxation. Elbow dislocations can be complete or partial. The elbow is the second most commonly dislocated joint in adults (after shoulder dislocations). When the joint surfaces of an elbow are forced apart, the elbow is dislocated. Welcome to Endurance Rehabilitation and Wellness Center, PC’s guide to elbow dislocation.
