Abstract

Günümüze değin proksimal n. ulnaris kompresyonu sendromunun oluşmasında, travmalar, tümörler, sulcus nervi ulnaris alanındaki iltihabi ve dejeneratif bozukluklar, doğuştan deformiteler, pozisyon hataları (yatışa bağlı felçler), kuvvetli gelişmiş arcus tendineus, m. fleksor carpi ulnaris'in baskısı gibi etkenler sorumlu tutulmuşlardır. Proksimal n. ulnaris kompressionu sendromu nedeniyle 85 vaka tarafımızdan ameliyat edilmiş, 11 vakada m. epitrochleo-anconaeus kası, 19 olguda da gelişmiş lig. epitrochleo-anconacum saptanmıştır. Bu vakalarda kas, dirsek ekleminin fleksionunda kasılarak özellikle kasın medial ve keskin kenarı ile bu sırada gerilen n. ulnaris üzerine basıyaptığını ve bunun sonucu oluşan mikrotravmaların birikerek pseudoneurom ve dolayısıyla kompression sendromunu meydana getirdiği görülmüş ve proksimal n. ulnaris kompression sendromunun oluşmasında ilk kez tarafımızdan sorumlu utulmuştur. Proksimal n. ulnaris kompresyonu vakaları içindeki m. epitrochleo-anconacum vakalarında, hastalık hikayesinin, diğer nedenlere göre uzun oluşu ve uyguladığımız sinir kaydırma, ameliyatı sonucu bu vakaların iyileşme oranlarının yüksek bulunuşu görüşümüzü desteklemektedir.

Responsibility of M. Epitrochleo-Anconaeus in Proximal N. Ulnaris Compression Syndrome

Abstract

Until recentiy, traumas, tümoral processes, inflammatory and degenerative changes of sulcus nervi ulnaris, congenital detormities, positilonal defects (paralysis related to Iying), strongiy developed arcus tendineus, pressure effect of m. flexor carpi ulnaris were thought to be the responsible causes of proximal nervus ulnaris compression syndrome. 85 cases were operated by us with the diagnosis of proximal nervus ulnaris compression syndrome and m. epitrochleo-anconaeus in 11 cases and overdeveloped ligamentum epitrochleo-anconaeus in 19 cases were observed as the etiologic cause. As a result of repsated flexion of the elbow joint, medial and sharp edge of the muscle compresses the stretched nervus ulnaris. Because of continuing microtrauma and preudo-neuroma formation subsegueni development of the proximal nervus ulnaris compression syndrome were first time described by us. The longer duration of complaints in those cases which m. epitrochleo- anconacus is responsible and good results of our nerve sliding technic encourages our approach.
