 Good morning, everyone. I'm Dr. Raul Thawar, junior resident in radio diagnosis in PJMS Rautabh. I'm presenting my oral paper on spinal pelvic alignment on MRI in young adults with spondylolystasis. Low back pain is one of the most common causes of medical visits globally. The prevalence of low back pain in adults has been recorded as high as 60% to 90%. Low back pain is a very frequent disease that most of the people experience at some point of their lives. One year incidence of first episode of low back pain is between 6.3% and 15.4%, whereas incidence of any episode of low back pain is between 1.5% and 36%. Normal spinal pelvic parameters leads to societal imbalance and contributes to multiple spinal conditions including isthmic spondylolysis, degenerative spondylolystasis, deformity and influence the outcome after spine correction surgery. Therefore restoration and maintenance of normal societal alignment is crucial for better outcomes of spine surgery. There is a great variation in societal spinal pelvic alignment in normal population with wide range of normal parameter. So an ideal societal alignment is one in which an individual is able to maintain a stable standing posture with minimum energy expenditure. There are a lot of parameters and angles in Lambo's sacro pelvic curvature that have been measured in many studies. Its effect on societal imbalance and disc regeneration has been done and these studies have different conclusions. Some of them use magnetic resonance imaging and x-rays while others used only x-rays. The purpose of our study is to evaluate spinal pelvic alignment on MRI in young Indian adults presenting with low back ache. To evaluate coronal and societal curvature of spine and its associated with spondylolystasis. To correlate between disc degeneration and patients with spondylolystasis. Materials and methods. 100 young Indian patients presenting to department of radio diagnosis with low back ache were studied by MRI. Whole body MRI was performed in relation to evaluation of the Lambo spine. These were then divided into following two groups. Degenerative spondylolystasis for the three of them and Degenerative disc disease and no spondylolystasis group that is NDLS 57. Inclusion criteria. All patients younger than and equal to 40 years with suspected disc degeneration presenting with back pain. Exclusion criteria. Patients greater than 40 years. Patient with recent and past age of significant trauma. Patients with clinical diagnosis of any inflammation or infection. Patients with suspected or diagnosed tumor. Patient with any congenital malformation except congenital lumbar spina stenosis. Patients with systemic disease. Patients with contraindications to MRI. Details of the imaging technique used. Patients with suspected spondylolystasis using MRI. Three Tesla MRI examination used following protocol. Whole spine T2 weighted societal imaging. Whole spine T1 weighted coronal imaging. Societal and axial images of the lumbar spine. Parameters used by societal vertical axis. Sacral angle. Sacral inclination. Sacrospinal angle. Sacral table angle. Vertical angle of the sacral curvature. Horacic kyphosis. Coronal imbalance. Sacral slope. Lumbar lordosis. Cobb angle. Cobb angle it is an angle between line drawn at the top of the superior. Tilted vertebra and the bottom of the inferior. Tilted vertebra. Statistical analysis. All the values are expressed as the mean. Standard deviation. Data is analyzed using the statistical package for the social sciences version. The comparison between parameters are performed using analysis of variance. For example, T test. One way T test was used for quantitative variables and level of sequence was set at 0.05. Results. Age. Age group of DLS Rubish 29.69 plus minus 5.26 years. Age group of NDLS Rubish 29.52 plus minus 6.57 years. Male ratio female of DLS Rubish 21 is to 22. Male ratio female of NDLS Rubish 28 is to 29. These are the following readings of the, these are the parameters. Then it's the DLS group. Then it's the details of this and DLS. Then it's the readings. All the readings are there. According to gender there being recorded and presented in the tabular form. This is for the female gender. All the parameters are mentioned here. No statistically significant correlation was found with respect to any of these parameters. Statistically significant difference was found between the two genders. That is male ratio female is 49 to 51 with respect to SVA, LL, SIN, VASC. However, only cobs angle was statistically different between the two groups when the genders were taken separately. There was positive SVN8 patients. That is 18.6% of the DLS group and of five patients. That is 8.8% of NDLS group. No significant correlation was found between SV of the two groups. Conclusion. This angle was significantly higher in the young Indian females while it was significantly lower in the males with DLS. Authors could not find any study on the Indian population. They also could not find a study with similar findings. However, most studies have been performed on parameters taken on X's and patients of all groups.
