|Enthesopathy is a disorder at the site of the insertion of ligaments, tendons, fascia, or articular capsule into bone (enthesis) and is the result of an inflammatory rheumatic or non-rheumatic disease process. In enthesopathy, pain develops in the free nerve endings of entheses (enthesalgia), becoming a source of chronic musculoskeletal pain in some individuals. This process also may promote abnormal calcification or ossification of the tendon or ligament at the insertion into the bone. |
Enthesopathy is a presenting part of many inflammatory conditions and is considered a process rather than a disease in itself. Conditions in which enthesopathy may develop include the spondyloarthropathies, septic arthritis, spinal arthritis, ankylosing spondylitis, reactive arthritis (reactive arthritis), psoriatic arthritis, enteropathic arthritis (accompanying ulcerative colitis and Crohn's disease), and such rare disorders as acne-associated arthritis, celiac disease, and Whipple disease. Enthesopathy is also seen as a complication of avulsion fractures and tendon tears (rarely).
When these inflammatory diseases develop, an enthesis can become irritated and painful, resulting in enthesopathy. The affected enthesis is found most commonly in peripheral joints such as foot joints, elbow and shoulder joints, or hip joints. Enthesopathy is not typically associated with traumatic injuries.
Risk: Enthesopathy is associated with the presence of inflammatory diseases and risk is highest in individuals diagnosed with rheumatic or non-rheumatic inflammatory conditions. Males and females are equally affected.
Incidence and Prevalence: Exact incidence cannot be estimated because of the broad range of inflammatory conditions that may result in enthesopathy and because the disorder may not be recorded as a separate diagnosis in patient records.
