The document from Khyber Medical College discusses the concept of anastomosis, focusing on its significance around the shoulder joint. It identifies three main anastomoses in this area—the scapular, acromial, and anastomosis around the surgical neck of the humerus—and outlines the arteries involved in each. Understanding these anastomoses is crucial for ensuring adequate blood supply and range of motion in the shoulder joint, particularly if there is a disruption in the axillary artery supply.

2. Outcomes :
At the end of the presentation, All the students must know about:
• What is anastomosis?
• Anastomosis around the shoulder joint.
• Artries involved in the anastomosis of shoulder joints.
• Importance of Anstomosis around shoulder joint

3. What is anastomosis?
• Communication between the neighboring
vessels
• Circulation through anastomosis is called Collatera
Circulation.

4. Anastomosis around Shoulder joint:
 There are three (3) Anastomosis Around shoulder joint;
1. The Scapular Anastomosis
2. The Acromial Anastomosis
3. Anastomosis around Surgical Neck of humerous

5. The Scapular Anastomosis:
• Occurs in the three fossa; Subscapular, supraspinous and
Infraspinous
• Between the subclavian artery and the third part of the axillary
artery.
Subclavian artry branches;
(a) The suprascapular artery, a branch of the thyro-cervical
trunk
(b) The deep branch of the transverse cervical artery, another
branch of the thyrocervical trunk
Axiilary artry branches;
(a) The circumflex scapular artery, a branch of the subscapular artery

7.  Occur above the acromial process
 Also between the Subcalavian and axillary Artery
Subclavian Branches;
Acromial Branches of;
(a) Thoraco-acromial Artery
(b) Supra-scapular artery
Axillary Branches;
(a) Acromial branch of Posterior Circumflex Humeral Artery
ACROMIAL ANASTOMOSIS

9. Anastomosis Around Surgical Neck of
Humerous:
• Occurs just below the surgical neck of Humerous
• Between the Branches 3rd part of axillary artery
• Two branches involved:
(a)Anterior circumflex humeral artery
(b)Posterior circumflex Humeral Artery

11. Importance of anastomosis around
shoulder joint
The shoulder joint has a wide range of movements
If, due to any reason, the axillary supply to the
shoulder region is interrupted
The subclavian supply to the region will compensate
the interuption or blockage
It’s the important clinical co-relation of anastomosis
