Paget's disease of bone (Siris and Roodman 2003) is a chronic bone remodelling illness that most usually affects the spine, pelvis, legs, or head (although any bone can be affected). Its impact can be reduced if detected early. Due to an increased number of hyperactive osteoclasts, people with this illness see an increase in bone loss at the afflicted region. While bone development rises to compensate for the loss, the quick synthesis of new bone causes the structure to become disordered. The resulting bone expands in size, which is linked to increased blood vessel and connective tissue production in the bone marrow. Despite the fact that Paget's disease is the second most popular bone disease after osteoporosis, many concerns about its pathophysiology remain unanswered. Paget's illness has a strong familial propensity, although no single genetic flaw has been identified that can account for all instances. Paget's disease can be passed down through generations in an affected family; 15–40% of patients have a relative who has the condition (Morales-Piga et al. 1995). Paget's illness can manifest itself in a variety of ways because it affects bones all over the body. An example scenario might be a man in his 60s who visits his doctor with hip pain. The doctor may diagnose him with arthritis and prescribe ibuprofen or acetaminophen (Tylenol). A normal screening may reveal a high alkaline phosphatase level several years later. This test would subsequently lead to the use of a bone scan and radiography, which would reveal Paget's femur and pelvic bone disease.
