What Causes Ankylosis?

Ankylosis is a term that describes stiffness in a joint. In most cases, the condition occurs because the joint has become fused. Rather than being a diagnosis of its own, ankylosis is often considered a symptom of a larger illness. Ankylosis is characterized by the joint's bones having abnormal rigidity and adhesion, restricting movement and can cause pain. The severity of the condition varies from case to case. For some patients, the joint's rigidity is complete, and they lose all ability to move said joint. For others, the rigidity is only partial.
