Bilateral pedicular stress fractures after successful posterior spinal fusion for adult idiopathic scoliosis.

A patient with adult idiopathic scoliosis who was successfully treated with posterior spinal fusion with segmental instrumentation from T3 to L4 is presented. One year after surgery fractures of both L4 pedicles developed, which were managed nonoperatively. Clinical union was achieved in 2 months and the patient was followed with serial computed tomographic scans to confirm union. A review of the current literature is also presented.
