Abstract
In this case report, we aim to present our observation of a rare variation on the dorsum of the foot, including the double deep fibular (peroneal) nerve and its connections to superficial nerves. The cutaneous nerves of both feet ' dorsum were examined during a routine dissection on a formalin-fixed adult male cadaver. During the dissection of the dorsum of the right foot, it was observed that the deep fibular nerve (DFN) surfaced at two distinct points by piercing the investing fascia. Then, these two branches converged, and DFN had connections at three different points with the superficial fibular (peroneal) nerve (SFN). However, the superficial nerve anatomy of the dorsum of the left foot exhibited the anatomical structure commonly described in classical textbooks. To the best of our knowledge, the variation of double DFN with multiple connections to the SFN has not been previously described in the literature. Understanding the innervation of the dorsum of the foot may be clinically substantial in preventing nerve injuries during surgical interventions. The knowledge regarding rare superficial nerve variations may contribute to the success of anaesthesia applications, especially in the ankle and dorsum of the foot.

Abstract
Bu vaka raporunda ayak sırtında çift nervus fibularis (peronealis) profundus (DFN) ve yüzeyel sinirlerle olan bağlantılarını içeren nadir bir varyasyona ilişkin gözlemimizi sunmayı amaçladık. Formalinle fikse edilmiş yetişkin bir erkek kadavra üzerinde rutin eğitim diseksiyonu sırasında her iki ayak sırtının kutanöz sinirleri incelendi. Sağ ayak sırtı diseksiyonu sırasında DFN’nin fascia investiens’i iki ayrı noktada delerek yüzeye çıktığı görüldü. Daha sonra bu iki dal birleşti ve DFN'nin nervus fibularis (peronealis) superficialis (SFN) ile üç farklı noktada bağlantısı oldu. Ancak sol ayak sırtının yüzeyel sinir anatomisi, klasik ders kitaplarında yaygın olarak tanımlanan anatomik yapıyı sergiliyordu. Bildiğimiz kadarıyla, çift DFN'nin SFN'ye çoklu bağlantılarla varyasyonu literatürde daha önce tanımlanmamıştır. Ayak sırtının innervasyonunun anlaşılması, cerrahi müdahaleler sırasında sinir yaralanmalarının önlenmesi açısından klinik açıdan önemli olabilir. Nadir görülen yüzeysel sinir varyasyonlarının bilinmesi, özellikle ayak bileği ve ayak sırtında anestezi uygulamalarının başarısına katkı sağlayabilir.
Ethical Statement
Çalışmamız, tıp fakültesi anatomi eğitim laboratuvarında bulunan, ulusal yasal ve etik prosedürler tamamlanarak elde edilmiş kadavra üzerinde yapılmıştır. Bu nedenle ayrı bir etik kurul onay belgesi bulunmamaktadır.
