Polymyalgia rheumatica is a rheumatic autoimmune inflammatory disease that affects the lining of the joints (synovitis) or around the joints (periarthritis). PMR doesn't usually cause joint destruction.
The place where a tendon or ligament meets bone is called an enthesis. Enthesopathy is an umbrella term for conditions that affect these connection points. This is where you will see inflammation in the spondyloarthritis family of diseases. Spondyloarthritis eventually causes joint damage. The defining characteristic of the spondyloarthritis family of diseases is enthesitis.
The synovium of a joint and enthesis are in the same vicinity. This is how PMR and spondyloarthitis are related but still different.
