In simple words: Paget's disease of bone is a condition where your bones break down and regrow abnormally. The new bone grows too fast, making it weaker and more likely to break. It can also cause pain, deformities, and other problems.

Osteitis deformans, also known as Paget’s disease of bone, is a chronic metabolic bone disease characterized by abnormal bone remodeling with excessive resorption and formation, resulting in weakened, enlarged, and deformed bones. This can lead to pain, fractures, arthritis, and other complications.

Example 1: A 65-year-old male presents with persistent bone pain and bowing of the legs. Imaging reveals enlarged and deformed bones in the legs and pelvis, consistent with Paget's disease., An 80-year-old female experiences a hip fracture after a minor fall. X-rays reveal characteristic changes of Paget's disease in the hip bone., A 70-year-old male is found to have elevated alkaline phosphatase levels during routine blood work. Further investigation with bone scan confirms the diagnosis of Paget's disease.

Documentation should include patient history, physical exam findings, imaging results (X-rays, CT, MRI, bone scan), DXA scan results, laboratory findings (alkaline phosphatase, bone markers), and details of treatment provided.

** Although the etiology of Paget's disease is unknown, genetic and environmental factors may play a role. The disease is more common in people over 50 and those of Northern European descent.
