Radial nerve palsy

[摘要] Injuries to the radial nerve can occur at any point along its anatomical route, and the aetiology is quite varied. As a result of its proximity to the humeral shaft, as well as its long and tortuous course, the radial nerve is the most frequently injured major nerve in the upper limb. Its close bony proximity makes it vulnerable to fractures of the humeral shaft and around the elbow. Injuries can be divided into high, complete radial nerve injuries and low, posterior interosseous radial nerve injury (PIN injury). Most injuries occur distal to the triceps muscle innervation. Radial nerve injuries are usually diagnosed through physical examination, though electrodiagnostic and radiological studies can help to identify the exact injury location and the degree of damage.
