Where is the suprascapular ligament?

Where is the suprascapular ligament?

The superior transverse ligament (transverse or suprascapular ligament) converts the suprascapular notch into a foramen or opening….

Superior transverse scapular ligament
The left shoulder and acromioclavicular joints, and the proper ligaments of the scapula.
From coracoid process
To suprascapular notch

What ligament covers the suprascapular notch?

The superior transverse scapular ligament (STSL) bridges the suprascapular notch, converting it into a suprascapular foramen. The suprascapular nerves and the vessels traverse through the suprascapular foramen of the scapula.

What is suprascapular region?

The scapular region is on the superior posterior surface of the trunk and is defined by the muscles that attach to the scapula (shoulder blade). These muscles can be divided into: As it continues laterally, this spine forms the acromion (the bony high point of the shoulder).

What nerve lies deep suprascapular ligament?

Anatomy: Motor nerve arising from the upper trunk of the brachial plexus (C5-6, occasional contribution from C4) Passes in close proximity to the posterior clavicle border to reach the suprascapular notch.

Where is the Coracoacromial ligament?

The coracoacromial ligament joins two parts of the shoulder blade (scapula), connecting the acromion to the coracoid process. It forms a part of a protective covering for the upper portion of the bone of the upper arm (humerus). Calcifications of the coracoacromial ligament can cause shoulder impingement syndrome.

Where is the Coracohumeral ligament?

The coracohumeral ligament is a broad band which strengthens the upper part of the capsule. It arises from the lateral border of the coracoid process, and passes obliquely downward and lateralward to the front of the greater tubercle of the humerus, blending with the tendon of the Supraspinatus.

What is the function of suprascapular notch?

The supra scapular notch is situated in the lateral part of the superior border of the scapula, adjacent to the base of the coracoid process. The notch is converted into a foramen by the transverse scapular ligament and it serves as a passage for the suprascapular nerve.

What is subscapular region?

The subscapularis muscle lies at the anterior surface of the scapula. It originates at the subscapular fossa, specifically the medial and lower two-thirds of the groove on the lateral border. The muscles transition to a tendon, which inserts on the lesser tubercle of the humerus in front of the joint capsule.

What part of the body is the scapular region?

The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.

What type of muscle is subscapularis?

The subscapularis is a triangular muscle that fills the subscapular fossa. The Subscapularis muscle is one of the rotator cuff muscles, helping to stabilize the head of the humerus in the glenoid fossa during shoulder movements.

What goes in the suprascapular notch?

The suprascapular nerve passes through the notch on its course over the scapula to the dorsal shoulder. The superior transverse scapular ligament passes over the notch and attaches to the base of the coracoid process. The suprascapular artery passes over the ligament.

What is the function of coracoacromial ligament?

The coracoacromial ligament (CAL) connects the acromion and coracoid process of the scapula, forming an osseoligamentous static restraint to superior humeral head displacement.

Where is the suprascapular ligament located in the body?

The suprascapular ligament extends from the medial aspect of the scapular notch on the superior surface of the scapula to the base of the coracoid process; thus converting it into the scapular foramen. The scapular foramen serves as a conduit for the suprascapular nerve, while the corresponding vasculature travels superior to the ligament.

Where does the suprascapular nerve travel through the body?

The suprascapular nerve (SSN) is a mixed nerve formed primarily by the C5 and C6 nerve roots and the upper trunk of the brachial plexus. The SSN travels deep to the trapezius (Trap) muscle and then enters the supraspinatus fossa. It then courses through the suprascapular notch underneath the superior transverse scapular ligament (STSL).

Is the scapular foramen superior to the suprascapular nerve?

The scapular foramen serves as a conduit for the suprascapular nerve, while the corresponding vasculature travels superior to the ligament. Use the following mnemonic to easily remember the neurovasculature arrangement passing through the suprascapular notch.

What causes damage to the suprascapular nerve in the arm?

Suprascapular nerve dysfunction can result from trauma, compression of the nerve by ganglion cysts, or traction from repetitive motion, particularly in athletes involved in sports that require overhead movement of the arm (overhead activities).
