Official Title: Evaluation and Treatment to Improve Bone Quality and Prevent Fractures by the Percutaneous Replacement of Diseased Tissue in Polyostotic Fibrous Dysplasia and McCune-Albri
Brief Summary:
This study will evaluate the effectiveness of a new bone injection technique for treating bone disease in patients with polyostotic fibrous dysplasia or McCune-Albright syndrome. In these patients, some bones develop areas with much less mineral, making the bones more prone to fracture or deformity and causing pain. This new treatment is intended to reduce the risk of fracture, minimize deformities and improve overall function in these patients.
Patients 4 years of age and older with bone lesions that are highly likely to cause significant pain and illness may be eligible for this 2-year study. Participants must be simultaneously enrolled in NIDCR's research protocol 98-D-0145 (Screening and Natural History of Patients with Polyostotic Fibrous Dysplasia and McCune-Albright Syndrome) or 98-D-0146 (A Randomized, Placebo-Controlled Trial of Alendronate in the Treatment of Polyostotic Fibrous Dysplasia and McCune-Albright Syndrome).
Within 14 days of the bone injection procedure, patients will have a medical history, routine blood tests, urinalysis and check of vital signs (blood pressure, pulse and temperature) and will complete a 30-minute quality-of-life questionnaire. Women of child-bearing potential will have a pregnancy test. Patients who do not have recent X-rays and bone density scans available for review will have new ones taken. When these studies are completed, patients will undergo the bone injection procedure, followed immediately by bone densitometry and coned-down X-rays, as follows:
