RESUMEN
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
RESUMEN
Introduction: The cervical region of vertebral column being the most common site of expression of stress in theform of pain in neck, cervical disc prolapse and cervical neuropraxia. Cervical vertebral column is influenced bymechanical, environmental, genetic, metabolic and hormonal factor and has to react to the forces of every day.Accurate anatomical descriptions of the pedicle, lamina and vertebral foramen are necessary for developmentand use of implantable devices and for spinal instrumentation that ranges from ‘transpedicular screw fixation’to ‘vertebroplasty’.Aim: To study the morphometric database of pedicles, laminae and vertebral foramina of subaxial cervicalvertebrae.Materials and Methods: Fifty-seven dry macerated sets of adult human cervical vertebral columns of unknownsex and age in the Department of Anatomy in Bharati Vidyapeeth University Medical College Pune and Smt.Kashibai Navale Medical College and General Hospital, Pune in Maharashtra. The length, thickness and heightof pedicles and laminae and anteroposterior and transverse length of vertebral foramina were measured withdigital Vernier caliperObservation: The pedicle length and thickness was found to increase uniformly from C3 to C7. Thickness oflamina was found to be maximum at C7 vertebra. Maximum anteroposterior length of vertebral foramen wasobserved at C3 and the maximum transverse length at C6.Conclusion: The result of this study will help in designing implants and instruments related to the cervicalvertebral column. It can also help in the management of traumatic and pathological fractures of cervical vertebralcolumn.
