Radial nerve compression or injury can occur at any point along the course of the nerve within the upper extremity. Entrapment of the radial nerve or its branches is most common within the proximal forearm and at the elbow. Variations in anatomic structures at this level are an important cause of radial nerve entrapment syndromes. Compression of the radial nerve and its branches at the elbow ca...

The radial nerve divides into two terminal branches the superficial and posterior interosseous nerve. Posterior entrapment is associated with weakness in extension of fingers, atrophy forearm muscles, localized pain lateral aspect elbow proximal without sensory deficits. A 37-year-old man complained difficulty right finger (MMT 2) persistent (VAS 5) at after a fall from motorcycle six months be...

A cause for spontaneous paralysis of the posterior interosseous nerve has been sought for many years. In recent times an increasing number of reports on this subject has appeared. Sharrard’s (1966) cases were of particular interest because the approach to the problem was direct. If the paralysis did not subside within six weeks, exploration was carried out promptly. He described a fibrous band ...
