title: Three-level bilateral pediculolysis following osteoporotic lumbar compression fracture.
abstract: BACKGROUND
  Osteoporotic compression fractures frequently occur at the thoracolumbar junction as a result of anterior column failure. Fractures of the pedicles are much less common and are not known to be associated with a prior compression fracture. Bilateral pedicle fractures over several consecutive lumbar levels in an osteoporotic elderly patient have not been previously reported.
  
  
  OBJECTIVE
  To draw attention to this unusual case and to review the relevant literature.
  
  
  METHODS
  A clinical case report of bilateral fractures of the pedicles from L3 through L5 in an 83-year-old male 2 years after an osteoporotic L3 compression fracture presenting with low back pain.
  
  
  METHODS
  An 83-year-old male presented with low back pain two years after sustaining osteoporotic compression fracture at L3 due to a fall. He had another minor fall and his radiographic workup revealed bilateral fractures of the pedicles of the L3, L4, and L5 vertebrae. The patient was treated nonoperatively.
  
  
  RESULTS
  The patient's symptoms improved without surgical intervention. Subsequent radiographic evaluation with plain films, computed tomography, and bone scan demonstrated union of the fractured pedicles.
  
  
  CONCLUSIONS
  In this uncommon case of bilateral lumbar pedicle fractures over three consecutive levels, isolated failure of the posterior rather than the anterior column occurred. This unusual fracture pattern may have been precipitated by the previous vertebral compression fracture. Nonsurgical management may result in acceptable clinical outcome.
