Extensor Digitorum Muscle Pain: Signs, Symptoms, Causes, Treatment, Risk Factors

About Extensor Digitorum, Its Origin & Function

The Extensor Digitorum Muscle which is also known by the name of Extensor Digitorum Communis muscle is an important muscle, which is located behind the forearm.1 The function of the Extensor Digitorum Muscle is to facilitate movements of the wrists and elbows. Additionally, it facilitates extension of the fingers II through V. The Extensor Digitorum Muscle originates from the lateral epicondyle and then it is divided into four tendons. These tendons traverse through an opening present in the lateral carpal ligament, which is present between a fibrous tissue sheath. These tendons ultimately become separate in the posterior portion of the hand and enter into the distal and middle finger phalanges. The tendons which enter the forefingers are interconnected with the help of slanting bands which are known as sagittal bands. The function of these bands is to keep the tendons correctly aligned above the metacarpal head.
