ABSTRACT
Introduction: It has been suggested that reduced inter-pedicular distance is one of the cause of primary narrowingof the spinal canal may lead to low back pain.Transpedicular approaches are being widely used in many surgeriessuch as bone biopsy, bone grafting, Pedicle screw fixation, vertebroplasty and kyphoplasty. The morphometricdata of lumbar vertebra from Udaipur district i.e. in southern Rajasthan is to the best of our knowledge, virtuallyunexplored so we under took this study.Aims and objectives: The present study aims at determining the morphometric norms of Pedicle of the lumbarvertebra in Udaipur zone measured in dried bone. In this study the following measurements on Pedicle of lumbarvertebra 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 variousmedical colleges of Udaipur. The morphometrical data of the Pedicle of human lumbar vertebrae were measuredand 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 Pedicleincreased from L1 to L5. Interpedicular distanced gradually increased from L1 to L5.
