Abstract

The musculocutaneous nerve arises from the

lateral cord of the brachial plexus. It innervates

muscles such as the biceps brachi and

brachialis. Ulnar nerve is the major terminal

branche of brachial Plexus. The deep motor

branch of the ulnar nerve is a terminal primarily

motor branch of the ulnar nerve. At its origin it

innervates the hypothenar muscles. Nerve

injury due to isolated trauma is rarely seen.

Musculocutaneous and deep ulnar motor

branch neuropathy can be caused by repetitive

trauma. We present report of two cases of (65

year old female and 40 year old male) isolated

nerve injury who complaine of atrophy painless

and weakness. Electrophysiological testing

revealed a musculocutaneous and deep ulnar

nerve neuropathy. Magnetic resonance imaging

and electrodiagnostic studies may be useful in

differentiating between these conditions. In the

literature, there are very few cases in which

ısolated lesions of the musculocutaneous and

deep ulnar motor nerves lesion have been

attributed to a single trauma.

TEK BİR TRAVMAYA BAĞLI GELİŞEN İZOLE PERİFERİK SİNİR NÖROPATISI: İKİ OLGU SUNUMU

Abstract

Muskulokutanöz sinir brakiyal pleksus lateral

kordundan ayrılır. Biceps braki ve brakiyalis gibi

kasları innerve eder. Ulnar sinir ise brakiyal pleksusun

major terminal dalıdır. Ulnar sinirin terminal

dalı derin ulnar motor daldır. Hipotenar

kasları innerve eder. İzole travmatik sinir hasarı

oldukça nadir görülmektedir. İzole travma nedeniyle

sinir hasarı gelişmesi nadir bir durumdur.

Biz bu yazıda atrofi ve ağrısız güçsüzlük yakınmasıyla

başvuran iki izole sinir hasarı olgusu

(65 yaşında kadın ve 40 yaşında erkek) sunduk.

Olgularımızdaki muskulokutanöz ve derin ulnar

motor dal nöropatisinin tek bir travmadan kaynaklandığını

düşünmekteyiz. Yapılan elektrodiagnostik

testler, izole muskulokutanöz ve derin

ulnar motor sinir nöropatisini göstermiştir.

Manyetik rezonans görüntüleme ve elektrofizyolojik

çalışmalar bu hastalıkların ayırıcı tanısında

faydalıdır. Literatürde izole muskulokutanöz

ve derin ulnar motor sinir hasarının, tek bir travma

nedeniyle oluştuğunu bildiren çok az sayıda

olgu sunumu vardır.
