AbstractIntroduction: Strong and large paired lumbar pedicles arise posterolaterally from each body near its upper border.The pedicles important role in transferring weight from neural arch to the vertebral columns. Because of sedentary lifestyle, road site accident and degenerative disorders of spine in old age leads to lumbar instability. So there needs open surgical intervention or sometimes percutaneous pedicle screw fixation may be done to stabilize the vertebrae. So morphometric study of lumbar pedicle helps surgeon for transpedicle screw fixation. The study aimed at measuring the various dimensions of pedicles in lumbar vertebrae and to compare present study with the previous one and discuss its clinical significance.
Material and Methods: This anatomical study was conducted on 60 lumbar vertebras of undecided sex and age for morphological study. The vertebral columns are collected from anatomy departments of various Medical Colleges of North Gujarat.
Results: The average width of pedicle at L5 level were most (16.45±2.31mm) and least at L1 level (7.67±2.20mm). The average height of pedicle at L1 level were most (14.80±1.43mm) and least at L5 level (13.83±1.54mm). The average cord length of pedicle at L4 level were most (46.67±4.21mm) and least at L5 level (44.12±3.90mm).
Conclusion: Morphometric knowledge of pedicles is vital and important for an orthopedic surgeons, anatomist, anthropologists, radiologists and forensic researchers.
