Morphometry of Pedicle and Vertebral Body in a Mexican Population by CT and Fluroscopy

It is necessary to have precise anatomical knowledge of lumbar pedicles for the safe placement of screws. There are not reports about the morphometry of lumbar pedicles in a Mexican population exist. A descriptive, observational and cross-sectional study was done in 60 cadavers from the dissection l...

There are not reports about the morphometry of lumbar pedicles in a Mexican population exist. A descriptive, observational and cross-sectional study was done in 60 cadavers from the dissection lab of the Human Anatomy Department of the Medicine School. The aim of the study was to quantify the morphometric characteristics of the pedicles of the lumbar spine in a Mexican population. A total of 60 cadavers were evaluated by fluoroscopy and CT from L1 to L5, in the age range of 40 to 78 years. Each vertebral pedicle was measured in the axial, sagittal and coronal planes. The measurements included the minimum pedicle width, the pedicle angle, the distance to anterior cortex, and anteroposterior and interpedicular spinal canal diameters. CT evaluation showed a progressive and gradual increase in the width of the pedicles from L1 (7.81 ±1.30 mm) to L5 (14.36 ±14.36 mm). A progressive and gradual decrease of pedicle length from L1 (20.92 ±2.62 mm) to L5 (17.23 ±1.35 mm). When fluoroscopy was used there was the same relationship, but the values were higher than those obtained by CT. The values for widths and lengths are slightly higher in males than in females, but do not reveal any significant difference (p<0.05). The data in this study indicates that pedicle screws (5.5-6.5mm) may be used in the lumbar region.info:eu-repo/semantics/openAccessSociedad Chilena de AnatomíaInternational Journal of Morphology v.27 n.4 20092009-12-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-95022009000400052en10.4067/S0717-95022009000400052
