| Summary: | Background: Spinal instrumentation has been increasingly used to treat degenerative spinal disorders. Adequate
anatomical knowledge of vertebral pedicles is necessary for proper instrumentation.
Objectives: This study aimed at typical lumbar vertebrae to understand various measurements of pedicle.
Materials and Methods: This study was conducted on 45 dry typical lumbar vertebrae obtained from Department of
Anatomy Shyam Shah Medical College, Rewa, Madhya Pradesh. Pedicle vertical height (h) and width (w) were taken with
the help of a sliding vernier caliper.
Results: It was found that the height of the typical lumbar pedicle varied between 10 and 16.1 mm whereas the width
varied between 4 and 19.6 mm.
Conclusion: Steffee pedicle screw of 4 mm size is safe in typical lumbar vertebrae for spinal instrumentation. |
