The suprascapular notch is an anatomical feature found on the scapula, a bone located in the shoulder region. It serves as a passageway for the suprascapular nerve and artery, which supply the supraspinatus and infraspinatus muscles. These muscles are responsible for the abduction and external rotation of the arm. The suprascapular notch is situated between the superior and lateral borders of the scapula and is closely related to the spine of the scapula, the acromion, and the coracoid process.
Best Structure for the Suprascapular Notch
The suprascapular notch is a small, triangular opening in the scapula (shoulder blade). It allows the suprascapular nerve and suprascapular artery to pass through to the supraspinatus and infraspinatus muscles.
Location
- The suprascapular notch is located on the superior border of the scapula, lateral to the coracoid process.
- It is bounded by the superior transverse scapular ligament and the coracoid process medially, and by the acromion process laterally.
Dimensions
- The average height of the suprascapular notch is 12 mm.
- The average width of the suprascapular notch is 10 mm.
Shape
- The suprascapular notch is typically triangular in shape, with the apex pointing medially.
- The base of the triangle is formed by the superior transverse scapular ligament and the coracoid process.
Clinical Significance
- The suprascapular notch is an important anatomical landmark for shoulder surgeons.
- It is commonly used as a reference point for arthroscopic shoulder procedures.
- The suprascapular notch can be compromised in certain shoulder injuries, such as dislocations and fractures.
Question 1:
Where is the suprascapular notch located?
Answer:
The suprascapular notch is located on the superior border of the scapula, just lateral to the coracoid process.
Question 2:
What is the function of the suprascapular notch?
Answer:
The suprascapular notch allows the suprascapular nerve and suprascapular artery to pass from the supraclavicular region to the infraspinous fossa.
Question 3:
Which bone articulates with the suprascapular notch?
Answer:
The suprascapular notch articulates with the clavicle via the coracoclavicular ligament.
