Abstract

A retrospective study to evaluate the clinical and electrophysiological profile of brachial plexus lesions in a tertiary care center of India. Thirty eight patients with brachial plexopathy (idiopathic or traumatic) with detailed electrophysiological studies were sampled. This included detailed motor and sensory nerve conduction studies of the conventional median, ulnar and radial nerves of the upper limbs, CMAP from deltoid, biceps and triceps on stimulating the ERB's point, needle EMG in the appropriate muscles and paraspinal muscles. The electrophysiological studies were performed on both sides irrespective of the clinical involvement and were recorded within 1.61 +/- 2.89 months in idiopathic group and 2.11 +/- 2.65 months in traumatic plexopathy group. The severity of involvement was assessed on MRC scale. ADL scale was used to assess the disability at presentation and subsequent follow up. 12 patients (11 male and 01 female) had idiopathic brachial plexopathy and 26 patients (all male) had traumatic brachial plexopathy. In the idiopathic group the lesion was localized to upper trunk in 58.3% of patients and middle trunk (posterior cord) in 41.66% and none had lower trunk or diffuse involvement. 25% had bilateral involveme...Continue Reading
