| Summary: | Introduction: Low back pain is the second most common
complaint encountered by primary care physicians.
Magnetic Resonance Imaging (MRI) is the modality of
choice for evaluation of low backache due to its superior
soft tissue contrast and safety. During last decade there
have been considerable developments in the techniques of
surgical treatment of spine for which detailed knowledge
of spine morphometry is required. The available lumbar
morphometric normograms are of few parameters which
are based on cadaver or radiographs which cannot be
directly applied on MRI to diagnose spinal stenosis or to plan
surgical treatment. Very few studies of MR morphometry
are available in world literature. Normal values for various
dimensions by MRI in Indian Population are lacking.
Aim: Develop a database of Bony Spinal Canal Area (BSCA),
Available Spinal Canal Area (ASCA), Pedical Length (PL)
and Neural Foraminal (NF) area on MRI in Indian subjects
and to determine difference between males and females
for these measurements.
Materials and Methods: In this cross-sectional study
lumbosacral was MRI performed on 50 volunteers in age
group of 18-30 years with no history of any spinal injury/
pathology/surgery. BSCA and ASCA, pedicle length and NF
area were measured and tabulated. The data obtained was
analysed by calculating mean, standard deviation and 95%
confidence limit. The gender relationship was analysed by
unpaired Student’s ‘t’-test. A two tail p-value of <0.05 was
taken as statistically significant.
Results: Normative morphological data for BSCA, ASCA,
pedicle length and NF area were prepared for lumbar
vertebra in a sample population of India. There was
statistically significant difference in bony and ASCA at L1
and L2 level. There was no statistically significant difference
on right and left side in either males or females for PL and
neural foramina area.
Conclusion: A database of clinically relevant measurements
of lumbar spine has been prepared and MRI can be used for
these parameters without radiation risk |
