The theory is that the radial nerve becomes irritated and/or inflamed from friction caused by compression by muscles in the forearm. [1]Some speculate that radial tunnel syndrome is a type of repetitive strain injury (RSI), but there is no detectable pathophysiology and even the existence of this disorder is questioned.
Examples of conditions that may sometimes be attributed to such causes include tendinosis (or less often tendinitis), carpal tunnel syndrome, cubital tunnel syndrome, De Quervain syndrome, thoracic outlet syndrome, intersection syndrome, golfer's elbow (medial epicondylitis), tennis elbow (lateral epicondylitis), trigger finger (so-called ...
Examples of injuries affected on an elbow include; Carpal tunnel syndrome, Radial Tunnel Syndrome and tennis elbow, all of which are due to tendon and ligament damage from overuse or strain. [ 7 ] [ 2 ] Distal humeral fractures are related to high energy trauma from falling from a height or in a motor vehicle accident, this results in stiffness ...
More serious cases often involve surgery, in which the nerve or the surrounding tissue is moved to relieve the pressure. Recovery from surgery can take awhile, but the prognosis is often a good one. Recovery often includes movement restrictions, and range of motion activities, and can last a few months (cubital and radial tunnel syndrome, 2).
If the pressure is removed the initial injury goes on to heal. The importance of this finding is that other conditions characterized by nocturnal or early morning symptoms may also be worsened by a “pathological sleep position.” We know this applies to carpal and cubital tunnel syndrome, plantar fasciitis, shoulder/neck pain and Gerd.
Carpal tunnel as seen on MRI. The carpal bones that make up the wrist form an arch which is convex on the dorsal side of the hand and concave on the palmar side. The groove on the palmar side, the sulcus carpi, is covered by the flexor retinaculum, a rigid band of fibrous tissue, thus forming the carpal tunnel.
Within the wrist: carpal tunnel syndrome. Common mechanism: carpal tunnel syndrome, an injury by nerve compression in the carpal tunnel, without transection of the median nerve, due to overuse by activities such as keyboard typing and cooking; Motor deficit: Weakness in flexion of radial half of digits and thumb, weakness in abduction and ...
If the swelling irritates the nerve, either because of the inflammation or simply because of pressure, the nerve can send sensations of pain, numbness, and/or tingling to the brain. This is called nerve entrapment. Nerve entrapment most frequently occurs at the wrist (carpal tunnel syndrome) and elbow (ulnar nerve entrapment).
