Brief Summary
This study will evaluate the effect of pamidronate a drug that decreases bone resorption (breakdown) on osteogenesis imperfecta. This is a genetic disorder of collagen, the major protein in bone. The abnormal collagen causes weak bones, and children with severe osteogenesis imperfecta sustain many fractures throughout their lives. They also have growth deficiency, curvature of the spine, crumbling teeth, hearing loss, easy bruising and heart and lung problems. The study will compare bone density, quality and strength, final adult height, trunk height, and functional ability in children who receive 1) pamidronate every 3 months, 2) pamidronate every 3 months + growth hormone injections, 3) pamidronate every 6 months, or 4) pamidronate every 6 months + growth hormone injections. Children 2 years of age and older with severe osteogenesis imperfecta (types III and IV) may be eligible for this study. Those enrolled will be randomly assigned to groups according to age; children two to four years of age will be randomly assigned to receive pamidronate every 3 or every 6 months. Children four years of age and older may participate in the growth hormone treatment groups. These children will continue on growth hormone until they reach their adult height or fail to grow as much as would be expected for someone on growth hormone. Patients will be followed in the clinic every 3 months for a history, physical examination, X-rays, blood tests, and measurements (weight, head circumference, and bone lengths). Children will receive a 3 to 4 hour infusion of pamidronate through an intravenous catheter (thin flexible tube placed in a vein) once a day for 3 days each visit. (Once inserted, the catheter is left in place to avoid multiple needle sticks for administering the drug and collecting blood samples.) Children who are taking growth hormone will be given the drug at the first treatment visit. At that time, the accompanying parent will be instructed on how to mix the drug and give injections. The child receives an injection 6 days a week (Sunday off).

Outcome Measures
Primary Outcomes (6)
Change in Bone Mineral Density in Response to Pamidronate
Dual-energy X-ray Absorptiometry (DXA) measurements were obtained using a Hologic QDR 4500 densitometer and low density software package. Measurements have a precision of 0.011 SD. Raw measurements were converted to Z-scores for analysis using the manufacturer's reference standards for age and pubertal status.

Eligibility Criteria
You may qualify if:
- Children enrolled in this study will be limited to those with Sillence types III and IV OI, as determined by clinical and genetic criteria.
- Most of the children who will be included in this study are already enrolled in the protocols Evaluation and Intervention for Ambulation, Growth, and Basilar Invagination in Osteogenesis Imperfecta (97-CH-0064) and Growth Hormone Therapy in Osteogenesis Imperfecta (92-CH-0034).
- Patients are excluded from protocol 92-CH-0034 if they have scoliosis of greater than 40 degrees unless scoliosis has been stable over the past two years, or evidence of severe basilar invagination.
- Patients with previous exposure to bisphosphonates in outside trials will be considered for participation in this trial.
You may not qualify if:
- Pregnancy.
- Patients that have had or will have surgery to place instrumentation in the spine (i.e. result of spine fusion).
