Abstract
5 elbow joints of 3 cadavers were dissected to investigate the anatomical characteristics of the lateral collateral ligament. We could identify the existence of the posterior fiber of the lateral collateral ligament in all cadavers.
The anterior fiber of the lateral collateral ligament ran from the lateral epicondyle to the annular ligament.
The posterior fiber originated from the lateral epicondyle and inserted into the crest of the supinator of the ulna.
We concluded that meticulous dissection was needed to identify the posterior fiber of the lateral collateral ligament and the posterior fiber had the important function of keeping the elbow stable.
