Radial Nerve Dysfunction: Causes, Symptoms, and Prevention
Medical professionals warn of radial nerve dysfunction, a condition that affects hand, wrist, and triceps movement and sensation. This nerve, named after its radial course in the arm, plays a crucial role in muscle control and feeling. The radial nerve originates from the brachial plexus, a network of nerves that branches out from the spine. It travels through the humerus' spiral groove and the arch formed by the humerus and triceps attachment. Notably, it passes through the Arcade of Frohse, a tunnel beneath the elbow, named after German anatomist Fritz Frohse. This nerve also aids in sensation in the hand and wrist, and controls the triceps muscle and wrist extension. Radial nerve dysfunction can stem from prolonged pressure, compression, or direct trauma. Common culprits include consistently wearing a tight watch, humerus fractures, improper crutch use, or certain sleeping positions. Damage to a single nerve group, like the radial nerve, is termed mono-neuropathy. Symptoms of radial nerve dysfunction include impaired hand, wrist, or triceps movement and altered sensation. If you suspect this condition, consult a healthcare professional promptly. Prevention involves avoiding prolonged pressure on the nerve and using equipment, like crutches, correctly.
