Management of an unstable lumbar fracture with a laminar split.

This is a case report describing the injury sustained by a 36-year-old man injured in a motorcycle crash who sustained a fracture dislocation of L2 upon L3, associated with a split in the lamina of L3. His neurologic lesion was T12 ASIA B: with a motor score of 52 but with preservation of sensory function (sensory score 96) in most parts of his lower extremities. He also suffered a lower extremity fracture. Imaging of the spine is presented showing a multiplanar fracture associated with translation and with a defect in the lamina that may be seen in certain AO type B or type C fractures, that may entrap the lumbar spinal nerve roots. Discussants of this case comment on the classification and clinical significance of this fracture pattern. and present their operative approaches, both for management of this particular fracture pattern and for any associated dural tear. The issues of steroid use and the place of rehabilitation are also discussed.
