Superior border of scapula

The superior border of scapula is the shortest and thinnest of the three borders and extends from the superior (medial) angle to the base of the coracoid process. This border is notable for several key anatomical structures and muscle attachments.

• Suprascapular notch: Located at the lateral part of the superior border, it is a deep, semicircular indentation partially formed by the base of the coracoid process. The notch is converted into a foramen by the superior transverse scapular ligament. The suprascapular artery and nerve pass through the suprascapular notch, with the artery typically running above the superior transverse scapular ligament and the nerve passing below it. This arrangement is crucial for surgical considerations and is a common site for nerve entrapment syndromes.

• Omohyoid muscle: The inferior belly of the omohyoid muscle attaches to the superior border of scapula, just medial to the suprascapular notch.
