Vascular Anastomosis Around the Elbow Joint

Introduction

The elbow joint is richly supplied by an extensive network of arterial anastomoses that ensure continuous blood flow even in cases of vascular obstruction. These anastomotic networks play a crucial role in maintaining circulation, particularly during flexion and extension movements of the arm.

Major Anastomotic Arterial Networks

Collaterals and Recurrent Arteries

The anastomoses around the elbow joint primarily involve:

• Superior and inferior ulnar collateral arteries
• Radial and middle collateral arteries
• Radial and ulnar recurrent arteries

Clinical Significance

Understanding these anastomotic networks is vital in surgical procedures such as elbow arthroplasty and arterial repairs. They also play a role in post-traumatic recovery following arterial injuries.

Conclusion

The vascular anastomoses around the elbow ensure continuous perfusion and support joint mobility, making them essential anatomical structures for both normal physiology and clinical interventions.
