Osteitis Deformans





Paget’s disease of the bone, initially referred to medically as osteitisdeformans, is a chronic condition of the bones that is characterized by enlarged and deformed bones of the body. This disease is said to be caused by a breakdown of bone material (referred to as bone remodeling), which then causes the affected bones to become weakened, misshapen, painful, and prone to fractures and injuries. Despite the seriousness of this condition, it does not generally affect the skeletal system; instead, it only limited to a few specific bones in the body.

This condition is named after Sir James Paget, an English surgeon and medical pathologist. The incidence rate of osteitisdeformans is placed at 3-5 cases per 10,000 persons. This condition usually affects the mature skeletal bones of adults, which then leads to the estimate that approximately 1-2% of the adults over the age of 55 in the United States have it. Yet, although osteitisdeformans commonly occurs in adults, there is a rare version of this disease that afflicts children, aptly named as juvenile Paget’s disease.



As with a number of other conditions, the cause for osteitiesdeformans or Paget’s disease of the bone is not yet known. With this, numerous theories have come up, in the hopes of explaining the underlying reason for this disease. Recent studies have suggested that family history and genetics may possibly play a role in the presence of this condition. This genetic factor is said to be triggered by systemic viral infections.

Environmental factors are also pointed out as possible causes for the occurrence of osteitisdeformans. Mechanical stress is high on the list of underlying reasons for this condition.


Signs and Symptoms

If the condition is a mild one, the person experiencing it usually does not notice any symptoms. Other people even go to the extent of confusing the disease as something else like arthritis or some other musculoskeletal ailment.

When symptoms do occur, osteitisdeformans may manifest the following:

  • Pain on the bones (specifically on the affected area);
  • Deformities in the bone (due to bone growth that is abnormal);
  • Bone fractures (because of bone remodeling, bones become more brittle and are more susceptible to injuries);
  • Loss of or decreased ability to hear (occurs only when the affected bone is in the skull); and
  • Varied levels of calcium and phosphate in the body.



Although a person with osteitisdeformans can survive without having the need for a cure, a treatment regimen may be advised by a doctor to lower the risk of having future complications and to control the pain experienced by the patient.

Orthotic aids can be utilized by individuals who have difficulty in walking or mobilization. Drug therapy is introduced to relieve pain and inflammation, and supplementation of calcium, vitamin D, and phosphate may also be called for. If the condition is really bad, then surgery might be in store for the patient.
