suprascapular artery

A branch of the thyrocervical trunk (from the subclavian artery); it runs over the superior transverse scapular ligament in the scapular notch and supplies blood to the supraspinous and infraspinous fossae. Its branches include the acromial arteries and it anastomoses with the subscapular and transverse cervical arteries.

Variations in suprascapular notch with or without an anomalous superior transverse scapular ligament is a cause for suprascapular nerve entrapment syndrome.
Background: The suprascapular notch of scapula is converted into a foramen by superior transverse scapular ligament (STSL) with the suprascapular nerve passing through the foramen and the suprasca-pular vessels passing above it.
Originating from the upper trunk of the brachial plexus, the suprascapular nerve passes through the suprascapular notch, beneath the transverse scapular ligament and sends motor branches to the supraspinatus muscle.
The transverse scapular ligament was transected to release the suprascapular nerve in the suprascapular notch.
Tountas & Bergman, 1993 say that these muscles include the scapuloclavicularis, a small muscle passing from the root of the coracoid process and transverse scapular ligament to the back of the clavicle, and pectoralis intermedius, a fleshy slip that arises from the third and fourth ribs between pectoralis major and minor and is inserted onto the coracoid process, derived from to the fifth cervical to first thoracic myotomes.
6) They reported that abduction or horizontal adduction of the shoulder exerted traction on the suprascapular nerve, which led to its compression against the superior transverse scapular ligament.
A foramen is formed after bridging of this notch by a strong fibrous band like structure namely suprascapular ligament or transverse scapular ligament.
The lateral part of superior border of scapula contains suprascapular notch which is bridged by superior transverse scapular ligament converting into foramen.
SUMMARY: Complete ossification of the superior transverse scapular ligament is generally considered to be rare and has not been previously described in an Indian.
3) In human, it is commonly bridged by superior transverse scapular ligament but by bone (ossified ligament) in some cases.
KEY WORDS: Superior transverse scapular ligament; Ossification; Entrapment neuropathy.
