El sırtı ve önkolun duyusal innervasyonunda farklı bir örnek

Bir erkek kadavranın sağ önkolunun 1/3 distalinde nervus cutaneus antebrachii lateralis (NCAL) ve ramus superficialis nervi radialis (RSNR)'in medial ve lateral dallara ayrıldığı, NCAL'in mediale giden liflerinin RSNR'in medial liflerine, NCAL'in laterale giden liflerinin RSNR'in lateral liflerine katılarak pleksus şeklinde anastomoz yaptığı gözlendi; sinirlerin innerve ettikleri bölge ve klinik uygulamalardaki öneminin belirlenmesi amaçlandı. RSNR'nin, n.radialis'den ayrılma yeri ile NCAL'nin medial ve lateral dallara ayrılma yerlerinin morfometrik değerlendirmesi yapıldı. Bu sinirlerin inerve ettikleri bölgeler belirlendi. NCAL ile RSNR arasında pleksus şeklindeki anastomozlar ve bu sinirlerin önkolda izledikleri yol, bu bölgenin cerrahi insizyon çizgilerinin çok yakınında seyretmektedir. İatrojenik yaralanmaları en aza indirebilmek için sinirlerin izledikleri yolun ve eğer varsa pleksus şeklindeki anastomozların belirgin anatomik noktalara uzaklığının bilinmesinin yararlı olabileceği sonucuna varıldı.

A different case for the sensitive innervation the dorsal aspect of the hand and forearm

In a case of a male cadaver, it has been observed that on the 1/3 of distal of his right forearm, lateral antebrachial cutaneous nerve (LACN) and superficial branch of radial nerve (SBRN) divide into medial and lateral branches, and LACN fibres going into laterals join SBNR's lateral fibres, causing anastomosis in a shape of plexus. The objectives were to determine the area innervated by the nerves and to emphasise its importance in clinical practices. The points where SBRN is divided from radial nerve and where LACN is divided into medial and lateral branches were morfometrically evaluated. Anastamoses in the shape of plexus between LACN and SBNR and route of these nerves follow along the forarm are very close to surgical incision lines of this area. It has been concluded that it will be useful to know the route of the nerves lead and the distance between anastamoses in the shape of plexus, if .there are any, and anatomic landmarks in order to reduce the risk of iatrogenic injuries.
