Anastomosis around shoulder joint, anatomy

Details of the arteries involved in the blood supply of shoulder joint. this is on of the major joint linking axial skeleton to the apendicular.

1. ‘A NASTOMOSIS AROUND THE SHOULDER JOINT ’ RASHEED UL HAQ Khyber Medical College, Peshawar, Pakistan. www.kmc.edu.pk

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 Collateral Circulation.

4. Anastomosis around Shoulder joint: There are three (3) Anastomosis Around shoulder joint; The Scapular Anastomosis The Acromial Anastomosis 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

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

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

8. 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
