Paget’s disease is a metabolic bone disorder in which the normal repair and renewal process within bone is disrupted.

Paget’s disease often causes no symptoms and may be found by chance. For those with symptoms these may include pain, deformity and fracture. Occurring more commonly with advancing age, Paget’s disease rarely occurs in those under 50. In the UK, it presents in approximately 8% of men and 5% of women, by the age of 80 years. Either single or multiple bones may be affected with common sites being the spine, skull, pelvis and thigh (femur).
