Abstract
Amaç: Çalışmanın amacı musculus
piriformis, siyatik sinir ve dallarının varyasyonlarını göstermek ve klinik
önemini tartışmaktır.
Gereç ve Yöntem: Ege Üniversitesi Tıp Fakültesi, Anatomi Anabilim Dalı’nda formalin ile
fikse edilmiş 26 erkek kadavraya ait 52 adet gluteal bölge ve alt ekstremite
değerlendirildi. Siyatik sinir ve musculus piriformis arasındaki anatomik
ilişki ile uylukta siyatik sinirin dallanma seviyesi kaydedildi.
Bulgular: Alt ekstremitelerin %84.62’sinde siyatik sinir pelvisten tek dal
halinde, varyasyonsuz olarak çıktı. Siyatik sinirin dallanma varyasyonu %23.08
olarak tespit edildi. On iki adet olarak bulunan yüksekten ayrılmanın 8’i
gluteal bölgede idi (%15.38). Dört alt ekstremitede (%7.69) nervus peroneus
communis ve nervus tibialis derin gluteal bölgeye foramen ischiadicum majus
yolu ile musculus piriformis’in altından ayrı ayrı girdi. Dört alt ekstremitede
ise (%7.69) iki ayrı dal musculus piriformis’in üzerinden, içinden (ya da
altından) geçti ve nervus tibialis musculus piriformis’in altından geçerken bu
iki dal da nervus peroneus communis’i oluşturmak üzere daha sonra birleşti. On
iki örneğin ikisinde, yüksekte ayrılma unilateral olarak uyluğun 1/3 üst
bölümünde izlendi. Siyatik sinirin fossa poplitea’da dallarına ayrılması da iki
alt ekstremitede görüldü (%3.85).
Sonuç: Siyatik sinirin musculus piriformis çevresindeki veya uyluktaki varyasyonları;
piriformis sendromu, total kalça protezi sonrası ortaya çıkan paralizi, gluteal
bölgeye uygulanan intramusküler enjeksiyonlar ve başarısız popliteal sinir
bloğu yönü ile tartışıldı.

Abstract
Aim: The
aim of present study was to demonstrate the variations of piriformis muscle,
sciatic nerve and its branches and discuss their clinical importance.
Materials and Methods: Fifty-two gluteal and lower limb regions of 26 formalin fixed male
cadavers were evaluated in Ege University Faculty of Medicine, Department of Anatomy.
The anatomical relationship between the sciatic nerve and the piriformis
muscle, and division level of sciatic nerve in thigh was recorded.
Results: The
sciatic nerve exited the pelvis as a single branch through the infrapiriform
foramen with no variation in 84.62% of the lower limbs. The division variations
of sciatic nerve were determined in 23.08%. In 8 of 12 high divisions were
observed in gluteal regions (15.38%). The common peroneal nerve and the tibial
nerve entered deep gluteal region via the greater sciatic foramen below
piriformis muscle separately in four lower limbs (7.69%). Two separate nerve
divisions passed above and through (or below) the piriformis muscle and then
combined together to form common peroneal nerve while tibial nerve passing
below the piriformis muscle in 4 lower limbs (7.69%). In 2 of 12, high division
occurred in the 1/3 upper portion of the thigh unilaterally (3.85%). The division
of sciatic nerve in the popliteal fossa was seen in two lower limbs (3.85%).
Conclusion: The clinical importance of the sciatic nerve around the piriformis
muscle or in the thigh was discussed for piriformis syndrome, palsy after total
hip arthroplasty, intramuscular injections in gluteal region and failed
popliteal nerve block.
