The same approach that works on the knee, scaled to other joints.
Fig. 01Embolization works the same way in the hip and shoulder as it does in the knee — fine catheters guided to the abnormal vessels feeding inflammation, particles delivered to close them off.
In any joint affected by chronic osteoarthritis or capsulitis, the same biological story plays out: the lining becomes chronically inflamed, the body grows abnormal blood vessels (neovessels) to sustain that inflammation, and the resulting nerve fiber growth produces persistent pain.
Hip embolization and shoulder embolization use the same image-guided technique pioneered for the knee. Through a fine catheter introduced through the wrist or upper thigh, microscopic particles are delivered into the abnormal vessels feeding inflammation — closing them off and quieting the pain at its source. The cartilage isn't restored, but the chronic inflammation that drives daily pain has its supply line cut.
Shoulder embolization is particularly well-studied for adhesive capsulitis (frozen shoulder) and rotator cuff-related pain. Hip embolization is most often used for moderate hip osteoarthritis in patients who aren't yet candidates for, or aren't ready for, hip replacement.
