Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 11
Abstract
The use of intralaminar screws (ILS), laminectomy and laminotomies are increasingly popular among spinal surgeons. A successful lamina surgery will require, sufficient understanding of the morphology and morphometry of the lamina. To our knowledge, there is little in the existing literature reporting on the morphometry of the lumbar spine lamina. 50 dry lumbar vertebrae were selected for the study and the morphometry of the lamina were recorded. The maximum mean height was recorded at L3 on the left and L2 on the right and gradually decreased towards L5.The width of the lamina showed a gradual increase from L1 to L5.The thickness was measured at 3 different levels, extending from upper to lower border of lamina. The mean thickness increased from upper border to the middle and then decreased towards the lower border in all the vertebrae from L1 to L5. In the present study the morphometry of the lamina of the lumbar vertebrae from L1 to L5 were recorded and presented. This may benefit the Spine Surgeons in the Decompression Surgeries like laminectomy done for the treatment of Spinal nerve Compression and also in the posterior spinal instrumentation using intralaminar screws and laminar hooks.
