Abstract

Isolated injury of the recurrent thenar branch of the median nerve is an unusual clinical entity causing thenar atrophy which must be distinguished from carpal tunnel syndrome. Electrophysiological studies show a prolonged terminal latency and denervation in the abductor pollicis brevis (APB) muscle with normal sensory nerve conduction in the finger-wrist segment. Here we report an 11-year old boy who presented with weakness of the APB muscle and atrophy of the thenar eminence. The electrophysiological studies showed the total denervation of the APB muscle, total axonal degeneration of the motor branch and normal sensory conduction of the median nerve.

Özet

Median sinirin rekürren tenar dalının izole tutuluşu nadir görülen bir durumdur, tenar atrofiye neden olur, karpal tünel sendromundan ayırımı yapılmalıdır. Elektrofizyolojik çalışmalar abduktor pollisis brevis (APB) kasında denervasyon ve motor distal latans uzamasına karşın parmak-bilek seğmenimde normal duyusal iletimi gösterir. Bu makalede sol elde kuvvetsizlik ve tenar kas atrofisi ile gelen 11 yaşında bir erkek hasta sunulmuştur. Elektrofizyolojik değerlendirmede APB kasında total denervasyon, median sinir motor dalında total aksonal dejenerasyona karşı normal duyusal iletim saptanmıştır.
