ICD-10: M89.579

Osteolysis, as classified under ICD-10 code M89.579, refers to the pathological process characterized by the progressive loss of bone tissue. This condition can occur in various anatomical locations, including the ankle and foot, and is categorized as "unspecified" when the exact cause or type of osteolysis is not clearly defined.

Clinical Description of Osteolysis

Definition and Pathophysiology

Osteolysis involves the resorption of bone, which can lead to weakened structural integrity and potential fractures. The process is typically mediated by osteoclasts, the cells responsible for bone resorption. Factors contributing to osteolysis can include:

• Infection: Osteomyelitis or other infections can lead to localized bone loss.
• Tumors: Malignant or benign tumors may induce osteolytic changes.
• Metabolic Disorders: Conditions such as hyperparathyroidism can result in increased osteoclastic activity.
• Trauma: Previous injuries may lead to localized osteolysis as part of the healing process or due to stress on the bone.

Symptoms

Patients with osteolysis in the ankle and foot may present with a variety of symptoms, including:

• Pain: Localized pain in the affected area, which may worsen with activity.
• Swelling: Inflammation and swelling around the ankle or foot.
