Cadaveric Study of Male Lumbar Intervertebral Foramina Morphometry in Ile-Ife
Background: This study was designed to investigate
the mean lumbar foramina height and length in male
cadaveric specimens in Ile-Ife. Aim and Objectives:
Two hundred and fifty intervertebral foramina derived
from twenty-five male cadaveric specimens were
analyzed, were studied. They were obtained from the
Department of Anatomy, Obafemi Awolowo
University, Ile-Ife, Osun State in Southwestern
Nigeria. The cadavers were positioned prone and a
routine paraspinal approach was employed to gain
exposure to the posterior spinal element following
meticulous soft tissue dissection. An osteotomy of the
iliac crest was performed to adequately expose the fifth
lumbar (L1-S1) foramina.Parameters assessed were;
the foramen height and the foraminal length. The
measurement was performed three times on each side
using vernier calipers. The variations of the different
measurements in the cephalo-caudal direction were
analyzed for statistical differences using the “One way
ANOVA” with post hoc test. Results: The result
showed a gradual increase of the foramina height were
observed on both right and left side from L1-L2 to L3-
L4 and from then on decreased progressively towards
the L5-S1 level. No statistical difference was noted in
the measurements derived (p<0.05). Conclusion: A
good understanding of the lumbar intervertebral
foraminal are essential in surgical planning of suitably
sized cannulas necessary for less invasive spine
surgeries as well as help in diagnosis of pathologies
surrounding this important region following adequate
clinical evaluation and measurements using imaging
