Ulnar neuropathy and dystonic flexion of the fourth and fifth digits: Clinical correlation in musicians

Abstract: Peripheral nerve lesions are sometimes associated with focal dystonia. We diagnosed ulnar neuropathy in 28 of 73 (40%) cases of occupational cramp in musicians. Focal slowing of ulnar conduction across the elbow was identified in 15 of 19 (79%) patients using the near nerve technique and in 5 of 17 (29%) patients using surface recording. Ulnar neuropathy was present in 24 of 31 (77%) cases with flexion dystonia of the fourth and fifth digits and only 4 of the remaining 42 (10%) cases with other patterns of foc… Show more

“…Several environmental risk factors have been described as potential triggers for the development of MD, such as an increase of practice time spent on the instrument, 1,3 or local pain or intensified sensory input due to various causes 1,3,18 before the onset of dystonia. On the basis of a given, most probably genetic susceptibility, these factors were hypothesized to trigger the manifestation of MD.…”

“…Nonetheless, as Bozentka (4) mentioned in his physiological study of this disorder, epidemiologic studies of occupational ulnar nerve entrapment at the elbow are rare (4). Most of the occupational studies are case reports in specific occupations or industrial sectors, such as driving (5), the shoe industry (6, 7), a bamboo toy factory (8), a surgical suture thread factory (9), occupations involving to hand-operated vibrating tools (10,11), and professional musicians (12). Most of them do not include an assessment of exposure to biomechanical factors.…”

“…Even more bodies of evidence suggest a direct causal relationship. Moreover, ulnar neuropathy has been described in musician's dystonia (21). However, it is of note, that even if the relationship between injury and the development of dystonia are common, not all patients with trauma develop dystonia.…”
