Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Calcitriol Supplementation
Active vitamin D metabolite (1,25-dihydroxyvitamin D3) administered to enhance intestinal calcium absorption and reduce bone density abnormalities. Requires monitoring of serum calcium levels to prevent hypercalcemia.
Targeted drug therapy with dose adjustment
Active treatment with regular monitoring by a healthcare provider is recommended.
Surgical Decompression
Neurosurgical intervention to relieve optic nerve compression or address spinal cord impingement caused by abnormally dense bone. Early intervention may prevent irreversible vision loss.
Additional treatment options
Hematopoietic Stem Cell Transplantation
Curative treatment approach replacing defective bone marrow cells with healthy donor stem cells. Restores normal osteoclast function and can halt disease progression when performed early.
procedureMobility and Strength Training
Specialized physical therapy program addressing skeletal deformities, joint stiffness, and muscle weakness. Focuses on maintaining functional mobility and preventing contractures.
physical_therapyMultisystem Surveillance Protocol
Comprehensive monitoring including annual ophthalmologic exams, hearing assessments, endocrine evaluation, and skeletal imaging. Early detection of complications allows timely intervention.
monitoringWhen to seek medical help
