[Myotendinitis crepitans of the abd. poll. long. and the ext. poll. brevis muscles with a reactive cheralgia paraesthetica (author's transl)].
15 patients--among them 10 bricklayers--were observed with a peracute painful swelling of the long abductor and the short extensor of the thumb following a short strain of the hand. This swelling could reach the size of an egg and was accompanied by crepitation which could be heard and felt. A concomitant neuralgic pain deriving from the superficial branch of the radial nerve was observed in 5 cases. The author discusses pathogenesis and therapy of this syndrome.
