[EX Q]: Abstract: During a 6-year period, 14 of 898 patients examined at a pediatric electromyographic laboratory had a compressive mononeuropathy. These included five injuries to the peroneal nerve, four to the sciatic nerve, two to the distal radial nerve, and one each to the deep palmar branch of the ulnar nerve, the musculocutaneous nerve, and the long thoracic nerve. A potentially preventable mechanism was identified in 9 of the 14 patients, including prolonged posture in three of the four sciatic and two of the peroneal neuropathies. Four other mononeuropathies were secondary to pressure from an orthopedic appliance or procedure (one injury to the musculocutaneous nerve, one to the long thoracic nerve, two to the peroneal nerve).

[EX Q]: Abstract: Severe traction injuries may damage the brachial plexus at any level from the spinal cord to the axillary outlet. Investigation aims to determine the level of the injury for each of the nerves, trunks or cords, with particular reference to obtaining firm evidence of any intradural (pre-ganglionic) damage. We report the results of computerised axial tomography of the cervical spine in comparison with conventional myelography and with surgical exploration of the plexus. CT scanning with contrast enhancement greatly improves diagnostic accuracy, particularly at C5 and C6 root levels.

[EX Q]: Abstract: Five clinical tests in common use for diagnosis of carpal tunnel syndromes have been shown to have little diagnostic value, either individually or in various combinations. No physical sign is useful in the diagnosis of this condition, which should be suspected on the basis of presenting symptoms and confirmed by electrodiagnosis using standard median nerve conduction tests.
