Anthropometric analysis of hip joint using Computed Tomography in a tertiary care centre in North India

Abstract

Background: Hip joint has a significant functional modification on erect bipedal posture. The geometry of the hip joint is determined by genetic and environmental factors such as age, race, sex, and lifestyle. Anthropometric dimensions described for hip joint in Westerners might be quite different from those encountered among Indians. So this study was aimed to do anthropometric study of Hip joint by CT scan. Material and Methods: The study was conducted on a CT pelvis of normal patients who underwent CT pelvis for some other reason and having both hip joints radiologically normal. This study was conducted in Department of Orthopedics, BPS Govt. Medical College, Khanpur Kalan, Sonepat, Haryana. Anthropometric measurements of 162 hips were carried out by CT scan of patient who underwent CT scan of pelvis for some other reason and have normal radiological hip with the age group between 20 years to 70 years. Total 8 parameter HD, NW, NSA, HO, VO, AA, CD_LT, AV of each hip joint were measured and compared between males and females and as per the side of the joint. Results: We found in our study that there is statistically significant difference between males and females in parameters like HD, NW, NSA, HO, VO, AA, CD_LT, AV. The mentioned parameter has lesser values in females than the males. We also found that there is no statistically significant difference as per the side of the joint in any parameter we studied. At the end of the study, we did a anthropometric study of the various parameter of the hip joint which may help for the better designing of the implants which are being used for hip surgeries and replacement surgeries. Conclusion: However, our study population was small up to 162 hips and large multicentric study may require supporting this finding.
