The use of technology in the treatment of degenerative spinal diseases has undergone rapid clinical and scientific development. It has been extensively studied in combination with various techniques for spinal stabilization from both the anterior and posterior approach. Minimally invasive and instrumental approach via posterior fixation is increasingly being used for the treatment of adult degenerative disc disease, stenosis, and deformity of the lumbar vertebrae. Posterior access to the lumbar disc spaces for posterolateral fusion scan has been technically challenging, frequently requiring the use of an approach surgery for adequate exposure. For successful surgery and suitable instrumental design, adequate anatomical knowledge of the lumbar vertebra is also needed. Anatomic features of lumbar vertebrae are of importance for posterior screw fixation technique. The morphometry of L1-L5 has been studied to facilitate the safe application of pedicle screws. Thus, we aimed to evaluate the morphometric landmarks of lumbar vertebrae such as pedicle, vertebral body, vertebral foramen, intervertebral space height and volume for safe surgical intervention using a posterior fixation approach to offer anatomical supports for lumbar discectomy, stenosis and cases of deformity. The features of the L1-L5 vertebral body, the detailed morphometric parameters of lumbar vertebrae and the intervertebral space were analyzed using computerized tomography scan, magnetic resonance imaging and also dry lumbar vertebrae. Additionally, intervertebral space volumes were measured using stereological methods to ensure safe surgical intervention. (C) 2011 Elsevier GmbH. All rights reserved.
