Neuropathy Radial Nerve Anatomy
To better understand radial tunnel syndrome, it helps to understand the anatomy of the elbow joint.
The elbow consists of three bones:
- The large, long bone in the upper arm
- The two prominent areas of the humerus on the inside and outside of the elbow are referred to as the epicondyles.
- The muscles that raise the wrist and hand attach to the lateral epicondyle.
- Muscles that flex the wrist attach to the medial epicondyle.
These three bones are bonded together by strong bands, called ligaments. The ligaments, muscles and tendons keep the bones of the elbow together during movement.
