Osteogenesis imperfecta

Case contributed by: Dr Frank Gaillard

Patient Data:

Age: Child

Bilateral long leg view

Modality: X-ray

Anterior view of both legs from hip to ankle demonstrates a number of features. Firstly there is evidence of a currently healing fracture of the proximal shaft of right femur, with two medullary pins. There is a degree of varus angulation. An old remodelled fracture of the left femur is also visible, with a minor degree of residual deformity. 

The long bones are gracile in shape with bowing most marked of the right tibia, but seen in all bones. Multiple somewhat evenly spaced sclerotic bands are seen in the distal metaphyses of the femurs, and proximal and distal metaphyses of the tibias and fibulas. 

Case Discussion:

This case demonstrates typical appearances of osteogenesis imperfecta in a patient receiving cyclical bisphosphonate therapy, e.g. pamidronate.
