Paget's sickness of bone (normally known as Paget's disease or, generally, osteitis deformans) is a condition including cell renovating and distortion of at least one bones. The influenced bones give indications of dysregulated bone redesigning at the infinitesimal level, explicitly over the top bone breakdown and ensuing disordered new bone development. These underlying changes cause the issue that remains to be worked out, which may bring about deformation, agony, crack, or joint inflammation of related joints [1].

The specific reason is unknown, although leading theories indicate both genetic and acquired factors (see causes). Paget's disease may influence any one or various bones of the body (most usually pelvis, tibia, femur, lumbar vertebrae, and skull), yet never the whole skeleton, and does not spread from bone to bone. Infrequently, a bone influenced by Paget's disease can change into a threatening bone malignancy.

As the disease frequently influences individuals in an unexpected way, therapies of Paget's disease can vary. Although there is no cure for Paget's disease, prescriptions (bisphosphonates and calcitonin) can assist with disorder and lessen pain and other symptoms. Medications are frequently fruitful in controlling the disorder, particularly when begun before difficulties start [2,3].

Paget’s disease of bone is a chronic (long-lasting) disorder that causes bones to grow larger and become weaker than normal. The disease usually affects just one or a few bones. The bones most affected by Paget’s disease include Pelvis; Skull; Spine; Femur and tibia (leg bones).

Many people with Paget’s disease do not experience symptoms specific to the disease. However, the bone changes can cause Bone pain, Misshapen bones, Broken bones (fractures), Inflammation and arthritis in the joints close to the affected bones.

With treatment, many people can manage their symptoms, improve pain, and control the effects of the disease.

Throughout your lifetime, the body constantly removes old bone and adds new bone to the skeleton. As we age, it is normal for this process to happen at a slower pace. As the disease starts, the body loses much more bone than it makes. As Paget’s disease progresses, new bone forms at a faster rate than the rate at which old bone is removed. However, the new bone does not form correctly, leading to larger bones that are misshapen, weaker, and softer than normal bone.

You may not know you have Paget’s disease because many people with the disease do not have symptoms. However, fractures or misshapen bones can develop and cause pain. Sometimes, this bone pain, which is the most common symptom of the disease, is mistaken for arthritis or other disorders. Generally, symptoms develop slowly, and the disease does not spread to normal bones.

Paget’s disease can affect any bone, but usually occurs in Spine, Pelvis, Femur and Tibia (leg bones), Skull.

In addition, some people with advanced disease may have misshapen bones and other bone changes, which may include Increase in head size, Bow shape of a limb, Curvature of the spine.

Other symptoms can develop, depending on the bone affected and can include Headaches and hearing loss when Paget’s disease affects the skull, Tingling and numbness in arms and legs when enlarged vertebrae put pressure on the nerves in the spine, Hip pain, which may occur when Paget’s disease affects the pelvis or thigh bone [4].

Depending on the bone or bones affected by Paget’s disease, other medical problems can develop, such as Damage to joint cartilage can lead to arthritis. Changes in the bones of the skull and ear can lead to hearing loss. For some people who have heart disease already and severe Paget’s disease, the extra workload of pumping blood throughout the body can lead to heart failure. Enlarged bones in the skull and spine can lead to pressure on the brain, spinal cord, or nerves and reduced blood flow to the brain and spinal cord. When Paget’s disease affects the facial bones, the teeth may loosen. This may make chewing more difficult. Rarely, people with Paget’s disease can develop bone cancer [5].
