Tunnel syndromes of the upper extremities in workers using hand-operated vibrating tools. 1994

National Institute of Occupational Health, Budapest, Hungary.

Neurological and electrophysiological (EMG, ENG) examinations of the upper extremities were carried out in 167 patients exposed to hand-arm vibrations. All patients had typical symptoms (Raynaud's phenomenon and/or numbness, muscle weakness). The results showed that the circumscribed lesions of the tunnel nerves are far more common (92.8%) than diffuse peripheral neuropathies (22.7%). The most common alteration (71.4% below the border-line values) was the lesion of the brachial plexus in the thoracic outlet. In 16.2% of the patients compression of the subclavian artery was also demonstrated by means of a Doppler flowmeter. Cubital tunnel syndrome was observed in 42.5% of the patients. The results suggest that hand-arm vibration can play a part in the development of the thoracic outlet and cubital tunnel syndromes. On the other hand the thoracic outlet syndrome can contribute to the development of vibration-induced Raynaud's phenomenon.

D013901	Thoracic Outlet Syndrome	A neurovascular syndrome associated with compression of the BRACHIAL PLEXUS; SUBCLAVIAN ARTERY; and SUBCLAVIAN VEIN at the superior thoracic outlet. This may result from a variety of anomalies such as a CERVICAL RIB, anomalous fascial bands, and abnormalities of the origin or insertion of the anterior or medial scalene muscles. Clinical features may include pain in the shoulder and neck region which radiates into the arm, PARESIS or PARALYSIS of brachial plexus innervated muscles, PARESTHESIA, loss of sensation, reduction of arterial pulses in the affected extremity, ISCHEMIA, and EDEMA.

D017769	Ulnar Nerve Compression Syndromes	Ulnar neuropathies caused by mechanical compression of the nerve at any location from its origin at the BRACHIAL PLEXUS to its terminations in the hand. Common sites of compression include the retroepicondylar groove, cubital tunnel at the elbow (CUBITAL TUNNEL SYNDROME), and Guyon's canal at the wrist. Clinical features depend on the site of injury, but may include weakness or paralysis of wrist flexion, finger flexion, and ulnar innervated intrinsic hand muscles, and impaired sensation over the ulnar aspect of the hand, fifth finger, and ulnar half of the ring finger.
