Radial nerve canal
The radial nerve canal is a narrow canal in the bones of the forearm and upper arm through which the radial nerve passes, which is a branch of the brachial plexus. This nerve is responsible for the functioning of the muscles of the forearm and hand, as well as for coordinating the movements of the hand. When this nerve is damaged or diseased, problems with movement, numbness, and tingling in the hand occur, which can lead to pain and impaired functionality of the hand. The radial nerve originates from the spinal cord in the cervical spine, so damage to it can be caused by injuries to the chest, upper extremities, or the nervous system as a whole. In addition, the radial nerve is sometimes damaged after surgery on the upper limb, during a stroke
