ICD-10: M90.671

Osteitis deformans, commonly known as Paget's disease of bone, is a chronic disorder characterized by the abnormal breakdown and formation of bone tissue, leading to enlarged and weakened bones. The ICD-10 code M90.671 specifically refers to osteitis deformans occurring in the context of neoplastic diseases, localized to the right ankle and foot.

Clinical Description

Overview of Osteitis Deformans

Osteitis deformans is primarily a disorder of bone remodeling, where the normal cycle of bone resorption and formation is disrupted. This results in bones that are structurally abnormal, often leading to pain, deformity, and an increased risk of fractures. The condition can affect any bone in the body but is most commonly seen in the pelvis, skull, spine, and long bones of the legs.

Association with Neoplastic Diseases

The designation of M90.671 indicates that the osteitis deformans is associated with neoplastic diseases, which may include various types of tumors, either benign or malignant. This association can complicate the clinical picture, as the presence of a neoplasm may influence the progression and symptoms of osteitis deformans.

Symptoms

Patients with osteitis deformans may experience:
- Bone Pain: Often localized to the affected area, such as the right ankle and foot in this case.
- Deformity: The affected bones may become enlarged and misshapen.
- Fractures: Weakened bones are more susceptible to fractures, which can occur with minimal trauma.
- Joint Issues: The abnormal bone structure can lead to joint pain and arthritis.

Diagnosis

Diagnosis typically involves:
- Imaging Studies: X-rays, MRI, or CT scans can reveal changes in bone structure characteristic of osteitis deformans.
- Bone Scans: These may be used to assess the extent of the disease.
- Laboratory Tests: Blood tests may show elevated alkaline phosphatase levels, indicating increased bone turnover.

Treatment

Management of osteitis deformans, particularly when associated with neoplastic diseases, may include:
- Medications: Bisphosphonates are commonly used to help regulate bone remodeling.
