Abstract
Introduction:The lumbar vertebrae are affected in conditions such as congenital defects, degenerative diseases, accidents, and cancer metastasis. A thorough knowledge of the morphometry of typical and atypical lumbar vertebrae in adults of South Indian population is needed for lumbar spine surgeries. MaterialsandMethods: Adescriptive study was done on 200 dry lumbar vertebrae, of which 100 were typical and 100 were atypical lumbar vertebrae. The following dimensions of both typical and atypical lumbar vertebrae were measured with digital vernier calipers: anteroposterior and transverse diameters of the body; anterior and posterior body heights; anteroposterior and transverse diameters of vertebral foramen; height, breadth, and width of the laminae; length, height, and width of the pedicles; transverse processes and spinous process; distance between the two superior articular processes; and the distance between the two inferior articular processes. All the measurements were tabulated. The mean and standard deviation were calculated for each of the parameters and the results were statistically analyzed. Results: The anteroposterior and transverse diameters of the body, the height of the laminae on both sides, the length and height of the spinous process, and the distance between the superior articular facets were significantly longer in atypical lumbar vertebrae than that of typical lumbar vertebrae (P < 0.05). There was no significant difference in measurements between both sides. Conclusion: The dimensions of vertebral foramen, transverse processes, spinous processes, and distance between articular processes were different from the dimensions of previous studies. The morphometric data obtained will be useful for orthopedic procedures on the lumbar vertebrae in South Indian population
