The Morphometric Study Of Intervertebral Foramen Of Lumbosacral (l1-s1) Region In Human Cadavers

ABSTRACT

Background and objective: The dimensions of intervertebral foramen can be altered by various factors. Theobjective of the present study was to measure the dimensions of L1-S1 intervertebral foramen and compare themon both sides and in both sexes.Methodology: The present study was conducted on 10 human cadavers (100 intervertebral foramina), collectedfrom the department of Anatomy, Mysore medical college and research institute, Mysore. Descriptive statistics,ANOVA (Analysis of Variance) and Independent t- test were used appropriately.Results: It was observed that the foramen height was more than foramen length (antero-posterior length) at alllevels. The foraminal height and length at the lower lumbar levels were significantly smaller than those at theupper levels. The difference observed in the morphometry of foramen on right and left side; and with respect togender was statistically not significant.Conclusions: The present study describes the normal parameters of intervertebral foramen.
