Abstract
Summary, conclusion and Recommendations Entrapment neuropathy is a group of focal neuropathy syndromes related to peripheral nerve compression resulting in pain, paresthesia, and loss of function of that nerve. The most common entrapment neuropathies in the upper limb are carpal tunnel syndrome, followed by cubital tunnel syndrome then Guyon’s canal syndrome. Diagnosis is based on clinical history, physical examination and electrophysiological studies, including electromyography and nerve conduction studies, however false negative and false positive NCS results do occur. Thirty patients with entrapment neuropathy of variable severity regarding NCS were included. All patients underwent high resolution ultra-sonographic imaging for evaluation of the affected nerve in both axial and longitudinal scans. The nerve was examined for its echotexture, fascicular pattern and cross sectional area was measured; also any associated pathology was examined. Our study showed that there was statistical significant agreement between ultrasonography and electrophysiological studies which is the gold standard in diagnosis of entrapment neuropathies and they complement each other, also there was an excellent correlation between the
