dc.description.abstractObjective: This study aimed to determine the anatomical fea tures and clinical significance of the spinoglenoid notch and spinoglenoid ligament-membrane as well as the branches of the suprascapular nerve to the infraspinatus muscle as these struc tures may cause compression of this nerve. Material and Methods: Fifty sides (25 right and 25 left) were studied on 26 fixed cadavers belonging to the Department of Anatomy, İstanbul University, İstanbul Faculty of Medicine. The suprascapular nerve branches to the infraspinatus muscle and spinoglenoid ligament-membrane were examined in cadavers, and the spinoglenoid notch was investigated in 50 dry scapulae. Result: The suprascapular nerve had two branches to the in fraspinatus muscle in 22 cadavers on 37 sides (74%) and three branches to this muscle in 11 cadavers on 13 sides (26%). On 31 sides the spinoglenoid membrane and on 19 sides the spinoglenoid ligament were observed. Related to the spinoglenoid notch, the mean width was 17.17±2.17 mm, and the mean depth was 17.45±2.03 mm in calliper measurements on dry bones, while the mean width was 16.99±1.88 mm, the mean depth was 17.73±2 mm and the mean area was 282.04±55.27 mm² in com puted tomography measurements. Conclusion: The presented data regarding the spinoglenoid notch in which the suprascapular nerve is frequently compressed and the branches of the suprascapular nerve to the infraspinatus muscle may guide the surgical treatment of the related entrap ment syndrome.
dc.description.abstractAmaç: Bu çalışmada, spinoglenoid çentik ve spinoglenoid ligament-membran ile supraskapular sinirin infraspinatus kasına giden dallarının anatomik özellikleri ve klinik öneminin belirlenmesi amaçlanmıştır, çünkü bu yapılar bu sinirin sıkışmasına neden olabilir. Gereç ve Yöntem: İstanbul Üniversitesi İstanbul Tıp Fakültesi Anatomi Anabilim Dalı'na ait 26 fikse kadavra üzerinde elli taraf (25 sağ ve 25 sol) çalışıldı. Kadavralarda infraspinatus kasına giden supraskapular sinir dalları ve spinoglenoid ligament membran incelendi ve 50 kuru skapulada spinoglenoid çentik araştırıldı. Bulgular: Supraskapular sinir, 37 taraftaki 22 kadavrada (%74) in fraspinatus kasına iki dal, 13 taraftaki 11 kadavrada (%26) ise bu kasa üç dal verdi. 31 tarafta spinoglenoid membran ve 19 tarafta spinoglenoid ligament gözlendi. Spinoglenoid çentik ile ilgili olarak kuru kemik üzerinde yapılan dijital kaliper ölçümlerinde ortalama genişlik 17,17±2,17 mm, ortalama derinlik 17,45±2,03 mm iken, bilgisayarlı tomografi ölçümlerinde ortalama genişlik 16,99±1,88 mm, ortalama derinlik 17,73±2 mm ve ortalama alan 282,04±55,27 mm² olarak bulundu. Sonuç: Supraskapular sinirin sıklıkla sıkıştığı spinoglenoid çen tik ve supraskapular sinirin infraspinatus kasına giden dalları ile ilgili sunulan veriler, ilgili tuzak sendromunun cerrahi tedavisine rehberlik edebilir
