ABSTRACT
Background: The frequent surgical interventions of thoracic spine are more common due to a wide array oftraumatic, degenerative and neoplastic diseases. For successful surgical management of these conditions, adetailed anatomical knowledge of the thoracic vertebrae is required.Aim: The aim of this study was to present a morphometric reference database for Pedicle morphometry of typicalthoracic vertebrae in Indian population.Material and methods: The study was conducted on 120 dry human typical (T2-T8) thoracic vertebrae selectedfrom the bone bank of the Department of Anatomy, SGT Medical College Hospital and research institute, Gurugram.Linear measurements of the vertebrae were taken with the help of digital Vernier caliper .Statistical Analysis:Mean and standard deviation of the morphometric parameters taken into account were analyzed. The comparisonof morphometric dimensions of the right and left sides was performed using Student’s t-test and p-value wascalculated.Results: The morphometric analysis of the thoracic vertebrae demonstrated that the Pedicle height (PH) was10.35 ± 1.22 mm and Pedicle Width (PW) was 5.65±2.06mm.Conclusion: The results provide a comprehensive database for more accurate modelling and design of vertebralbody implants and instrumentations for Indian population.
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.
