Osteitis Deformans is a bone disorder that is also known as Paget's disease. Paget's disease is characterized by abnormal bone growth and remodeling. There are several synonyms for Osteitis Deformans, including osteodystrophy, osteogenic hyperplasia, and hyperostosis. While these terms may sound complex, they all refer to the same condition of abnormal bone growth. Osteitis Deformans primarily affects older adults, and it is often asymptomatic. However, when symptoms do occur, they can include bone pain, deformity, fractures, and arthritis. While there is no known cure for Osteitis Deformans, treatment can help manage symptoms and prevent complications.
