Abstract
Introduction The diameter of the quadrupled Hamstring graft plays a significant role in the incidence of graft failures for ACL reconstruction. The ability to predict the graft size pre-operatively can prepare the surgeon for alternatives in the event of an inadequate graft diameter. Materials and methods We retrospectively measured the diameter of the Semitendinosus tendon (ST) on the MRI in all patients who underwent arthroscopic ACL reconstruction using quadrupled Semitendinosus as their graft. We also estimated any correlation between various anthropometric data with pre-operative MRI based Cross Sectional Area (CSA) of the Hamstring tendon and final graft diameter in the South Asian population. The patients were included from Jan 2018 - Dec 2020. Results The minimum CSA of ST to predict an eventual graft diameter of 7.5mm was 10.7mm2. The MRI based cross-sectional area measurement showed moderate correlation with the intra-operative graft diameter obtained. (r=0.62, p<0.001). The intra-class correlation coefficient between the radiologist and the surgeon was 0.82, 95% CI (0.57, 0.92) and a p-value <0.001. Conclusion Pre-operative MRI can be a useful tool to predict the graft diameter. This coupled with the anthropometric data of the patient can be used as an adjunct to estimate the probable graft diameter. Thus, the surgeon can be better prepared for the surgery and can seek alternate graft options if the graft size is deemed inadequate pre-operatively.

Mathew A, Panwar J, Shanmugasundaram D, Thomas BP. Will preoperative combined MRI and high-resolution ultrasonography redefine brachial plexus imaging? A comparative study of preoperative MRI versus combined MRI and high-resolution ultrasonography in assessing usable C5, C6 root-stumps for intra-plexal nerve grafting.

Abstract
AIM To compare the intraoperative findings with the preoperative imaging in detecting usable root stumps using magnetic resonance imaging (MRI) alone versus MRI combined with high-resolution ultrasonography (HRUS) in adults undergoing post-traumatic brachial plexus (BP) surgery. Further, when root stumps were present, the reliability of their measurements using both imaging methods was compared to their intraoperative length. MATERIALS AND METHODS A consecutive group of adults who were planned for post-traumatic BP surgery between July 2015 and April 2016 were evaluated prospectively. They underwent preoperative MRI and HRUS and the agreement (kappa value) between these imaging methods and their intraoperative findings in categorising roots were then compared. When stumps were present, the reliability of the extraforaminal measurements by each method were compared to their corresponding intraoperative stump length using intraclass correlation coefficients (ICC), and Bland-Altman plots. RESULTS Of the initial 60 patients, 48 patients with 82 roots were included in the study. Greater agreement was observed between HRUS and intraoperative findings in categorising BP root stumps (kappa value 0.70, SE 0.07) versus MRI and intraoperative findings (kappa value 0.42, SE 0.07). Similarly, there was a higher correlation between HRUS and intraoperative findings (ICC: 0.94, p<0.001) than that of MRI and intraoperative findings (ICC: 0.53, p<0.001) regarding stump length measurements. CONCLUSION Combining HRUS with MRI in the preoperative imaging of the adult BP injury can better predict the presence of usable nerve root stumps for intra-plexal nerve grafting. HRUS also gave reliable preoperative stump length measurements, and it was determined that a stump should be at least 1.3 cm to be deemed usable for nerve grafting.

Abstract
Magnetic resonance imaging (MRI) is an increasingly important tool for identifying involvement of the sacroiliac joints (SIJ) in juvenile idiopathic arthritis (JIA). The key feature for diagnosing active sacroiliitis is bone marrow edema (BME), but other features of active arthritis such as joint space inflammation, inflammation in an erosion cavity, capsulitis and enthesitis can be seen as well. Structural changes may also be seen. Systematic MRI assessment of inflammation and structural damage may aid in monitoring the disease course, choice of therapeutics and evaluating treatment response. In this pictorial essay, we illustrate normal MRI findings and growth-related changes of the SIJ in the pediatric population, as well as the different MRI features of SIJ inflammation. This atlas demonstrates fundamental MRI disease features of active inflammation in a format that can serve as a reference for assessing SIJ arthritis according to the updated preliminary JAMRIS (Juvenile Idiopathic Arthritis MRI Score) scoring system proposed by the MRI in JIA working group of Outcome Measures in Rheumatology and Clinical Trials (OMERACT). The atlas is intended to be read in conjunction with its companion Part 2, Structural Lesions.

Abstract
OBJECTIVE The aim of the study was to determine if frequency of tooth cleaning varies with social group, family size, bedtime and other personal hygiene habits among school children. METHODS Target population comprised schoolchildren aged 8-16 years of Udaipur district attending public schools. A two stage cluster random sampling procedure was executed to collect the representative sample, consequently final sample size accounted to 852 children. Data were collected by means of structured questionnaires which consisted of questions related to oral hygiene habits including a few general hygiene habits, bed time, family size, family income and dental visiting habits. RESULTS The results show that 30.5% of the total sample cleaned their teeth twice or more daily and there was no significant difference between the genders for tooth cleaning frequency. Logistic regression analysis revealed that older children and those having less than two siblings were more likely to clean their teeth twice a day than the younger ones and children with more than two siblings. Furthermore, frequency of tooth cleaning was significantly lower among children of parents with low level of education and less annual income as compared with those of high education and more annual income. In addition, tooth cleaning habits were more regular in children using tooth paste and regularly visiting to the dentist. CONCLUSIONS This study observed that tooth cleaning is not an isolated behaviour, but is a part of multifarious pattern of various social and behavioural factors.
