154 Study of interpedicular distance in lumbar vertebral canal in western population of Rajasthan Meghna Bhaumik ∗ , Uday Bhaumik, Neelam Bapna Geetanjali Medical College, Udaipur, India Introduction: Lumbar canal stenosis is one among the causative factors producing low back-pain. Stenosis caused by reduced sagittal diameter of spinal canal is the prime factor but the importance of reduction in size of lumbar spinal canal due to reduced interpedicular distance is of similar value. Aim and objective: Therefore the present study was designed and conducted in SMS Medical College, Jaipur, Rajasthan with the objectives to evaluate the normal ranges of inter-pedicular distances in Rajasthani population and also to determine the differences of diameter between both sexes. Material and method: Total number of approximately 1000 patients suffering from low back-pain reported in various OPD at S.M.S. Hospital were taken as subject within age group of 20–60 years and natives of Rajasthan state. The AP radiographs were taken and IPD was measured by digital Vernier calipers. Result: There is a cranio-caudal increase in IPD of L1–L5 vertebrae and values for IPD are higher in males than females at all vertebral level.

Foramen ovale transmits the mandibular nerve, accessory meningeal artery, lesser petrosal nerve, emissary vein and occasionally the anterior trunk of the middle meningeal vein. Foramen spinosum gives passage to middle meningeal vessels and nervous spinosus. Study of anatomical variations of these foramina will add important information useful in skull base injury and helpful for procedures like transfacial fine needle aspiration technique, percutaneous trigeminal rhizotomy for trigeminal neuralgia, etc. Material and method: 60 dry human skulls were obtained from the department of anatomy, Sawai Man Singh Medical College, Jaipur. The length, width and shape of foramen ovale and spinosum were measured by vernier caliper. Mean and range was calculated and tabulated. Results: The mean length of foramen ovale was 7.98 mm and 4.24 mm on right side and 7.14 mm and 3.78 mm on left side. Most common shape observed was ovale (74%). The mean length and width of foramen spinosum was 3.14 mm and 2.68 mm on the right side and3.05 mm and 2.58 mm on left side. The most common shape observed was rounded (58.5%). Conclusion: No significant difference was found between the foramen spinosum of both sides whereas significant difference was observed in the size of foramen ovale. The knowledge of foramina is helpful for the neurosurgeons and radiologists.
N.S.C.B. Medical College, Jabalpur, India Background: The foramen magnum is a large oval opening in the skull base lying in the posterior cranial fossa. The dimensions of foramen magnum are clinically important because many vital structures pass through it, i.e. the lower part of medulla oblongata, the meninges, vertebral arteries, spinal accessory nerve, etc. The dimensions of foramen magnum are also used for sex determination in forensics. The knowledge of foramen magnum diameters is needed to determine some malformations like Arnold Chiari syndrome which shows expansion of transverse diameter. Objectives: To study diameters (longitudinal and transverse) and calculate area of foramen magnum. Materials and methods: 100 dry skulls were studied and the antero-posterior and transverse diameters of foramen magnum were measured using Vernier calipers. The area of foramen magnum was calculated. Result: It was observed that the mean sagittal diameters were greater than the mean transverse diameters and this is also consistent with the shape of the foramen. The mean sagittal diameter in the present study is 3.35 cm and the mean transverse diameter is 2.61 cm. The mean area in the present study is 6.86 cm2 . Discussion: The diameters are in accordance with the shape of foramen magnum and are in agreement with the previous studies.

Kavipriya Chennai Medical College and Research Centre, Trichy, Tamilnadu, India Introduction: Low back pain is a very common complaint occurring between 30 and 60 years of life and about 80% of the world population suffers from it at least once in their life time. The lumbosacral region is the main weight bearing region of the entire vertebral column. Lumbosacral angle (LA) may be affected by conditions such as inflammation, degenerative changes, age, trauma, surgery, race and ethnicity. Previous studies have reported varied values for the normal average lumbosacral angle. And so, this study was done to measure lumbosacral angle in south Tamilnadu population.
