Clinical Causes: Genetic predisposition, often involving mutations in genes regulating bone remodeling (e.g., SQSTM1 gene). Age-related changes, with a higher prevalence in individuals over 55. Environmental factors that may influence bone turnover, though specific triggers are not fully understood.

Key Symptoms: Bone pain, which may be persistent or intermittent. Bone deformities, such as bowing or enlargement of the thigh. Muscle weakness or difficulty moving the affected limb. Increased warmth or a buzzing sensation over the affected area due to increased blood flow. Fractures, especially with minor trauma, due to weakened bone structure. In some cases, no symptoms are present, and the condition is identified through imaging for other reasons.

Diagnosis Path: Physical examination to assess deformities, tenderness, and function of the thigh. Radiographic imaging (X-rays) revealing characteristic changes such as enlarged, bowed bones with patchy areas of sclerosis and lytic lesions. Bone scans to identify areas of increased metabolic activity indicative of active disease. Blood tests measuring levels of alkaline phosphatase, which are typically elevated in active Paget's disease. Optional genetic testing for mutations associated with the condition, especially in familial cases.

Treatment Protocols: Medications such as bisphosphonates to reduce abnormal bone turnover and control symptoms. Pain management through analgesics and anti-inflammatory drugs. Physical therapy aimed at improving mobility, muscle strength, and function. Surgical interventions, if necessary, for severe deformities or fractures, including corrective osteotomies or joint replacements. Regular monitoring to assess disease activity and prevent complications like fractures or secondary osteoarthritis. Lifestyle adjustments, including weight management and avoiding excessive strain on affected bones, may support overall bone health.
