Abstract

The pedicle is the strongest part of the vertebra and Pedicle screws are used to anchor other surgical devices used in a variety of surgical procedures relating to the spine. The concept of using pedicle screw to help arthrodesis was first described by King in 1944. In 1970, Roy-Camille first applied the pedicle screw plating system for the lumbar spine. Many systems are used that incorporate plates, hook and rod system (Harrington and Moe) and external pins to obtain secure purchase of the vertebrae. A descriptive cross-sectional study was conducted in the Department of Orthopaedics and data was collected from the Department of Radio-Diagnosis, S. Nijalingappa Medical College and Hanagal Shri Kumareshwar Hospital and Research Centre Bagalkot, by using CT scan images of the patients undergoing CT KUB for unrelated disease. A total of 30 adult individuals (15 males and 15 females) were included for the study. In our study, it was reported that the pedicle height was gradually decreasing from L1 to L5 on both sides in both genders. The average height in this plane was reported to mean range from 11.82 mm in the L1 vertebra to 8.03 mm in the L5 vertebra.
