Morphometric Study of Pedicles of Dried Adult Human Lumbar Vertebrae in Udaipur Zone

Abstract

It has been suggested that reduced inter-pedicular distance is one of the cause of primary narrowing of the spinal canal may lead to low back pain.Transpedicular approaches are being widely used in many surgeries such as bone biopsy, bone grafting, Pedicle screw fixation, vertebroplasty and kyphoplasty. The morphometric data of lumbar vertebra from Udaipur district i.e. in southern Rajasthan is to the best of our knowledge, virtually unexplored so we under took this study.Aims and objectives: The present study aims at determining the morphometric norms of Pedicle of the lumbar vertebra in Udaipur zone measured in dried bone. In this study the following measurements on Pedicle of lumbar vertebra are taken i.e. pedicle height, pedicle width and Interpedicular distance. Materials and methods:The present study was done on the 110 dry adult human lumbar vertebrae from various medical colleges of Udaipur. The morphometrical data of the Pedicle of human lumbar vertebrae were measured and analysed. Digital vernier calliper was used to measure the morphometric data.Result and discussion: The pedicle height of Pedicle decreased from L1 to L5 except in L2 and width of Pedicle increased from L1 to L5. Interpedicular distanced gradually increased from L1 to L5.

A morphometric analysis of pedicles of lumbar vertebrae by using computed tomography scan

“…A study revealed that the mean pedicle breadth gradually decreases from L1 to L5 vertebrae 23 which is consistent with the present study. However, a study amongst Saudi Arabian population had found a gradual increasing pattern of pedicle breadth from L1 to L5 in both genders 8 .…”

“…In a study on lumbar vertebrae, the mean pedicle breadth was noticed to have insignificant differences between right and left sides 10 which is consistent with the present study except at L2 and L4. These results are also supported by a study in which the breadth was not found to have significant differences between right and left pedicles 23 which is also consistent with this study. A study also observed that mean pedicle breadth values were found to have significant differences between males and females 8 which is different to this study except at L1.…”

“…Another study also reported that the breadth of the pedicle gradually increases from L1 to L3 vertebrae and again decreases at L4 and L5 25 . Another study also observed that the breadth of pedicles decreases gradually from L1 to L5 except at L2 where it increased (maximum at L2) 23 . A study in Nepal, observed that the breadth of pedicles increases from L1 to L2 and decreases from L2 to L5 26 .…”

“…A study done in Mangalore, Karnataka, South India revealed that the breadth of both the pedicles increases from L1 to L2, then decreases from L2 to L3 and again increases from L3 to L5 27 . But a study claimed that the breadth of pedicles decreased from L1 to L5 except at L2 where it was maximum increased at L2 23 .…”

Morphometric Study of Lumbar Vertebrae in South Indian Population

“…low back pain is a musculoskeletal condition affecting the adults (Vinaya Swetha, yuvaraj babu and Mohanraj, 2018). It is one of the main health problems all over the world and around 75% of the population is estimated to have experienced it at least at some point of their life (Choubisa andbabel, 2018) (banik et al, 2019). lumbar spinal stenosis is the common cause in older age group which is narrowing of the spinal canal in which the antero-posterior and lateral measurements of the canal are less than the normal value for the particular age and sex.…”
