Nervus suralis'in unilateral varyasyonu: Bir kadavra çalışması

Bu çalışmada formalin ile fikse edilmiş beyaz, erişkin bir kadın kadavrada sağ bacak arka bölgesinin diseksiyonu sırasında n. suralis yapısının fossa poplitea'nın alt sınırının 10.55 mm aşağısında oluştuğunu tespit ettik (Şekil 1, 'E' transvers hattı). Çalışmamızda bacak topografisi ile ilgili mesafeler ve sinir uzunlukları 0,01 mm hassasiyeti olan dijital bir kumpas kullanılarak ölçülmüştür. Konunun daha kolay anlaşılır olmasını sağlamak amacıyla diseksiyon sahası fotoğraf üzerinde şematize edilerek anatomik lokalizasyonlar işaretlenmiştir (Şekil 1)

Unilateral variation of sural nerve: a cadaver study

We identified a superiorly located sural nerve formation 10.55 mm under the popliteal fossa of right sural nerve during the dissection of right volar surface in a white adult female cadaver. Examining the leg, the digital caliper length of lateral sural cutaneous nerve originating from common fibular nerve was 11.76 mm and medial sural cutaneous nerve branching from tibial nerve was 13.88 mm. We identified that medial sural cutaneous nerve, normally branching from between the two heads of gastrocnemius muscle, branches at a superior region, in the lower margin of popliteal fossa. This is a single-sided variation in which sural nerve forms superiorly. Clinically, these types of variations are vital in diagnostic invasive interventions, angiographic applications and treatment surgeries of the region.
