Blood Supply of Joints� Articular & epiphysial branches.

� circulus articularis vasculosus.

� The articular cartilage is avascular.

Nerve Supply of Joints• Capsule & Ligaments : Rich

nerve supply

• Synovial membrane : Poor nerve supply

• Articular cartilage : Non –nervous

• Hiltons law

Dislocation of Joint

� Articular surface of joint are abnormally displaced.

� Subluxation:
