Foremen scapulae osseum

Dicle Üniversitesi Tıp Fakültesi Anatomi Anabilim Dalı'nda bulunan scapula kemiklerinden bir tanesinde foramen scapulae ossesum anomalisi saptadık. Proc.coracoideus'un tabanının medialinde bulunan incisura scapulae'nın, lig.transversum scapula superius'un ossifiye olmasıyla foramen scapulae osseum'a dönüştüğünü gözlemledik. Oluşabilecek dar bir for.scapulae osseum, n.suprascapularis'in periferik kısmına tam bir baskı oluşturabilir (m.supraspinatus ve m.infraspinatus parezisi). Bu anomalinin n.suprascapularis'in parazilerinin değerlendirilmesinde önemli bir yeri vardır.

Foremen scapulae osseum

We determined that anomaly of foramen scapula osseum on a skeleton of left scapula which has been in Department of Anatomy in Medical Faculty of Dicle University. Incisura scapulae, just medial to the basis of the coracoid process, we observed that the superior transverse scapular ligament ossifies, resulting in a complete osseous passage which is named foramen scapula osseum. A very narrow scapular foramen can produce a complete peripheral compression syndrome of the suprascapular nerve (paresis of supraspinatus and infraspinatus muscles). That variation may an important role for determining in paresis of suprascapular nerve.
