Enthesophytes (less commonly, enthesiophytes) are bony proliferations (spurs) that develop at an enthesis, that is at the attachment of a ligament, tendon or articular capsule onto bone. They are oriented along the direction of pull and develop in response to repetitive mechanical stress or a more generalized inflammatory condition.
They may be mistaken for osteophytes and are seen more commonly in patients that have many or large osteophytes (bone-formers) .
- enthesophytes are associated with enthesopathy and enthesitis
- enthesophytes can fracture causing pain
- seronegative spondyloarthritides
- diabetes mellitus
- diffuse idiopathic skeletal hyperostosis (DISH)
