Ultrasound detection of sciatic nerve movements with ankle dorsiflexion/plantar flexion: Prospective comparative study of a novel method to locate the sciatic nerve

Objectives: It is possible to observe the in-vivo movements of nerves using real-time ultrasound. In this study, we aimed to visualize the movements of the sciatic nerve as a guide to identify the sciatic nerve to distinguish from surrounding tissue. Methods: This trial was a prospective, cross-over comparative study. We included 25 healthy volunteers in this study. The movements of the sciatic nerve were visualized in the transverse view at popliteal and midthigh levels using ultrasonography. Anterior-posterior movements were assessed by measuring skin-to-nerve distance. The distances were measured during maximum ankle dorsiflxion, maximum plantar flxion and neutral position and compared with each other. We also evaluated the quality of dynamic (real-time) rotation/lateral movements of the sciatic nerve by assigning a subjective observer score. Results: The movement of sciatic nerve was signifiant at popliteal region with active and passive ankle dorsiflxion which was 0.32 cm and 0.23 cm respectively (p=0.003). The movement of sciatic nerve was signifiant at midthigh region with active and passive ankle plantar flxion which was 0.11 cm and 0.01 cm respectively (p

Siyatik sinir hareketinin ayak bileği dorsifleksiyon ve plantar fleksiyonuyla ultrason eşliğinde görüntülenmesi: Siyatik sinirin yerinin belirlenmesinde yeni bir yöntem

Amaç: Sinirlerin in vivo hareketlerini gerçek zamanlı ultrason kullanarak gözlemlemek mümkündür. Siyatik siniri etrafındaki dokudan ayırt etmek ve tanımlamak için bir kılavuz olarak hareketlerini göstermeyi amaçladık. Gereç ve Yöntem: Bu araştırma prospektif çapraz karşılaştırmalı çalışma olarak planlandı. Bu çalışmaya, 25 gönüllü dahil ettik. Siyatik sinirin hareketleri ultrasonografi kullanılarak popliteal ve orta uyluk seviyelerinde enine kesitlerde görüntülendi. Ciltsinir mesafesi ölçülerek sinirin ön-arka hareketi değerlendirildi. Mesafeler, maksimum ayak bileği dorsiflksiyonu, maksimum plantar flksiyon ve nötr pozisyonda ölçüldü ve birbirleriyle karşılaştırıldı. Ayrıca, siyatik sinirin dinamik (gerçek zamanlı) rotasyon/lateral hareketleri subjektif bir gözlemci puanı verilerek değerlendirildi. Bulgular: Siyatik sinirin hareketi popliteal bölgede aktif ve pasif ayak bileği dorsiflksiyonunda, sırasıyla 0,32 cm ve 0,23 cm olarak ölçüldü ve anlamlı bulundu (p=0,003). Siyatik sinirin hareketi orta uylukta, aktif ve pasif ayak bileği plantar flksiyonu ile sırasıyla 0,11 cm ve 0,01 cm olarak ölçüldü (p
