Introduction: The acetabulum is a cup shaped hemispherical depression which is present on the hip bone, contributed by ilium, ischium and pubis. It has a central depressed non-articular part called acetabular fossa, surrounded by a curved lunate articular surface which articulates with the head of femur to form hip joint. The knowledge of acetabular dimensions assists the radiologists in diagnosing acetabular dysplasia and aids the surgeon to determine the correct size of the acetabular cup during total hip arthroplasty and to realign the acetabulum back to normal position. Aim: To measure and analyse the relationship between the depth and diameter of acetabulum and also to study the variations in the morphology of anterior acetabular ridge. Materials and Methods: A cross-sectional study was done on 104 unpaired dry human adult hip bones from February 2017 to September 2019 after obtaining ethical clearance. The diameter and depth of acetabulum was measured using vernier calliper and a metallic strip and correlation between them were analysed using Pearson’s test. Student’s t-test was used to test the significance between the variables. The p-value <0.05 were considered as statistically significant. The different shapes of anterior acetabular ridge were noted. All the recorded data were analysed using Statistical Package for the Social Sciences (SPSS version 16.0). Results: The average measurements of acetabular diameter and depth were 48.98±2.91 mm and 24.12±2.54 mm, respectively. A positive and a significant correlation was found between diameter and depth of the acetabulum (r=0.388, p<0.001). The mean values of diameter and depth of acetabulum in right side were 48.76±2.94 mm and 23.6±2.48 mm, respectively. The average values of diameter and depth in left side were 49.2±2.92 mm and 24.6±2.59 mm, respectively. Though the measurements of acetabular dimensions on left side were slightly greater than right side, they were not statistically significant (p>0.05). Four different shapes of anterior acetabular ridges were noted: angular (23.08%), curved (63.46%), straight (2.88%) and irregular (10.58%). Conclusion: The present study showed weakly positive correlation between diameter and depth of the acetabulum and morphological variations in the shape of anterior acetabular ridge.

Background: The myocardial infarction (MI), the most common manifestation of coronary artery disease remains as a major cause of mortality in both developed and developing countries. The people without known major risk factors can be screened for MI with a simple and cost-effective tool which will be helpful in developing countries to reduce the mortality. Dermatoglyphic patterns in clinical conditions have been studied so far and their relationship is established in the literature. Dermatoglyphics has been considered as a diagnostic tool in many diseases with genetic bases. Hence this study is conducted to analyse the correlation between dermatoglyphic features and MI, so that dermatoglyphics may be used as screening tool for MI. Materials and Methods: We conducted a cross-sectional study of 150 MI patients diagnosed with ECG or coronary angiography who were admitted in the Institute of cardiology, Madras Medical College, Chennai after obtaining clearance from Institutional ethics committee. 150 healthy consented volunteers were included as controls. The finger prints from both groups were taken by ink method and type of fingerprint patterns and total finger ridge count (TFRC) and absolute finger ridge count (AFRC) were studied. The correlation of the findings between cases and controls were analysed with t-test and Chi-square test using SPSS 13.0. Results: The frequency of loop, arch and whorls is 54.9%, 8.3% and 36.8% respectively in MI as compared to 59.4%, 13.2% and 27.4% respectively in controls. The frequency of whorls is increased in thumb, middle finger and little finger of both hands of the MI patients when compared with controls with statistically significant difference (p<0.005). The mean value of TFRC and AFRC is increased in cases than controls and statistically significant difference was observed for AFRC. Conclusion: Thus, our study has indicated the specific fingerprint patterns in MI and we hope this knowledge can be used for screening the people without known risk factors for MI.
