Intravenous bisphosphonate therapy for children who have a traumatic fracture neck of femur and osteonecrosis: a case report.

Intravenous bisphosphonate is an expecting medication to reduce femoral head resorption and to prevent femoral head collapse after traumatic osteonecrosis. This mechanism will reduce development of osteoarthritis and disability in the future.
