Abstract
br>In the lumbar spine, the body’s center of gravity falls at or posterior to the vertebral axis. Slight flexion decreases the lordosis and places the axial load force-of-injury vector through the vertebral body.
from a neurological standpoint, the content and size of the neural canal distinguish the lumbar area from other regions. The cauda equina alone occupies the spinal canal at and caudad to the second lumbar level. Additionally the dimensions of the spinal canal are wider here than in any other region
Management of fracture lumbar spine starts with proper diagnosis. History, clinical examination standard X-ray, computerized tomography and magnetic resonance imaging.
- Denis classification of spinal fractures proved to be practical in evaluation in our patients.
- Load sharing classification gives an excellent and simple way to assess the damage done to the anterior column during the fracture.
- Patients were managed operatively with unstable fractures with or without neural affection.
- Operative treatment with posterior approach by fixation in all cases, by:
- Decompression by laminectomy in all cases with neural affection. Indirect reduction (by distraction .Direct reduction by impaction of the fragments anteriorly.
- In most cases decortication and posterolateral bone graft were made in most cases.
