Paget’s disease of bone


Paget’s disease of bone, also referred to as osteitis deformans, is a chronic and uncommon bone condition characterized by abnormal and disproportionate bone remodeling, involving both excessive bone resorption and formation. With time, the bones affected by Paget’s disease can become misshapen and weakened, leading to increased susceptibility to fractures. The bones that are typically impacted include the pelvis, skull, spine, and legs, among others.

Paget’s disease accelerates the process of bone regeneration beyond normal rates, resulting in the formation of new bone tissue that is less structured and more fragile than healthy bone. This can cause bone pain, deformities, and a higher risk of fractures. If Paget’s disease affects a joint, it can result in the development of arthritis in that area.

Age and the family history of the condition both increases the likelihood of Paget’s disease of the bones. However, the disease has been less common over the past few years and less severe when it develops. Broken bones, hearing loss, and spinal nerve compression are examples of complications.

The primary therapy involves bisphosphonates, which are drugs used to rebuild bones that have been weakened by osteoporosis. In the event of complications, surgery can be required.


Many people are unaware that they have Paget’s disease of the bones, which can be asymptomatic or present with mild symptoms. When symptoms do occur, bone pain is the most common complaint. Symptoms of Paget’s disease can resemble those of other bone conditions, such as arthritis.

The symptoms of Paget’s disease of the bone vary based on which bones are affected, and if left untreated, Paget’s disease often worsens gradually over time. Bone Paget’s disease symptoms and warning indicators might include:

  • Skull: Hearing loss or headaches can be brought on by an excessive development of bone in the skull.
  • Spine: Compressed nerve roots can occur if the spine is affected. An arm or leg may experience discomfort, tingling, or numbness as a result. In advanced cases of Paget’s disease of the bones, various types of bone deformities can occur.
  • Pelvis: Hip pain may be brought on by Paget’s disease of the pelvic bone.
  • Leg: The patient may become bowlegged as the bones deteriorate and perhaps bend. Osteoarthritis in the knee or hip may result from the legs’ enlarged and deformed bones, which can increase the stress on the surrounding joints.

It is important to seek medical attention if you experience any bone or joint pain, tingling or weakness in your extremities, bone deformities, hearing loss, or headaches, as these could be symptoms of Paget’s disease of the bones.


The cause of Paget’s disease of the bones is currently unknown, although researchers suggest that a combination of genetic and environmental factors may play a role in its development. Several genes have been linked to the condition. Additionally, there are some hypotheses that propose the possibility of Paget’s disease of the bones being caused by a viral infection in the bone cells.

Risk factors

Factors that can increase your risk of Paget’s disease of bone include:

  • Age: The condition most frequently affect people over 50.
  • Family history: Individuals with a family history of Paget’s disease of the bones may have a higher risk of developing the condition.
  • Gender: Males are affected more frequently than women.
  • Race: England, Scotland, central Europe, Greece, and countries where European immigrants have settled, Paget’s disease of the bone is more prevalent.
