Abstract

Anatomi kitaplarında n. medianus ve n. ulnaris’in elin palmar bölgesindeki dağılımı radial taraf 3,5 ve ulnar taraf 1,5 parmak (sırasıyla) olacak şekilde tanımlanmıştır. Berrettini, 1741 yılında elin palmar bölgesinde n. medianus ve n. ulnaris arasında bir bağlantı tanımlamıştır. Bu bağlantı “Berrettini anastomozu” olarak literatürde yer almıştır. Elin palmar bölgesindeki bu sinirlerin bağlantısı Terminologia Anatomica’da “ramus communicans cum nervo ulnari” olarak isimlendirilmiştir. Ancak, temel anatomi kitaplarında bu bağlantıya ve detaylarına yer verilmemiştir. 64 yaşındaki erkek kadavranın sağ elinin rutin diseksiyonu esnasında n. ulnaris ile n. medianus arasında bir bağlantı olduğu gözlendi. Bu sinirlere ait dalların dağılımı takip edildi. N. ulnaris’in 1,5; n. medianus’un 2,5 ve n. ulnaris ile n. medianus kökenli ortak dalın dördüncü ve üçüncü parmaklarının yarısına dağıldığı tek taraflı olarak tespit edildi. Sol elde bu bağlantıya rastlanmadı.Literatürde n. ulnaris ve n. medianus kökenli bu sinirin frekansı %4 ile %94 arasında olduğu belirtilmiştir. Tagil ve ark.’nın çalışmasında bu bağlantının Türk popülasyonundaki oranı %60 olarak bulunmuştur. Bu varyasyonun toplumda bulunma sıklığına bağlı olarak bazı yazarlar, elin palmar bölgesinde n. medianus ve n. ulnaris’in dağılımında bu bağlantının normal bir dağılım paterni olarak yer almasını talep etmektedir.

“Ramus Communicans Cum Nervo Ulnari” Between Ulnar Nerve and Median Nerve in Palmar Region

Abstract

In anatomy textbooks the distribution of the median and ulnar nerves has been described as 3,5 and 1,5 digits (respectively) in the palmar region of the hand. Berretini, in 1741, described a connection between ulnar and median nerves in the palmar region of the hand. This connection has been reported in the literature as “Berrettini anastomosis”. The communication of the nerves in the palmar region of the hand was named as ‘ramus communicans cum nervo ulnari’ in Terminologia Anatomica. However, in major textbooks, this communication and its detail, hasn’t been mentioned. During the routine dissection of the right hand of 64-year-old male cadaver, a communication between ulnar and median nerves was observed. The distribution of the branches of those nerves were traced. It was noticed that the ulnar nerve was distributed to 1,5 digits, the median nerve distributed 2,5 digits and the common branch raised from the ulnar and median nerves distributed 0,5 of 4th and 0,5 3rd digits, unilaterally. This connection was not found in the left hand.The frequency of the nerve originated from ulnar and median nerves was declared between 4% and 94% in literature. In the study of Tagıl et al. they found 60% incidence of this connection in Turkish population. On the rely of the frequency of that variation, some authors have been claimed that this connection should have taken place
