ISOLATED PERIPHERAL NERVE NEUROPATHY ASSOCIATED WIHT A SINGLE TRAVMA: REPORT OF TWO CASES

The musculocutaneous nerve arises from the lateral cord of the brachial plexus. It innervates muscles such as the biceps brachi and brachialis. Ulnar nerve is the major terminal branche of brachial Plexus. The deep motor branch of the ulnar nerve is a terminal primarily motor branch of the ulnar nerve. At its origin it innervates the hypothenar muscles. Nerve injury due to isolated trauma is rarely seen. Musculocutaneous and deep ulnar motor branch neuropathy can be caused by repetitive trauma. We present report of two cases of (65 year old female and 40 year old male) isolated nerve injury who complaine of atrophy painless and weakness. Electrophysiological testing revealed a musculocutaneous and deep ulnar nerve neuropathy. Magnetic resonance imaging and electrodiagnostic studies may be useful in differentiating between these conditions. In the literature, there are very few cases in which ？solated lesions of the musculocutaneous and deep ulnar motor nerves lesion have been attributed to a single trauma
