Design and Development of Fixture for Flexural Testing of Lumbar Spine
Degenerative lumbar spinal stenosis is the most common reason for lumbar surgery in patients. The standard surgical management is decompression of the spinal canal by laminectomy and bilateral laminotomy. In this paper, the effect of this surgical procedures & its mechanical behaviour is determined by using a specially designed fixture for flexural testing of animal's lumber spine. By using this fixture, a constant moment generated through the axial movement of the UTM actuator is applied to the spine specimen to achieve the various degree of motions. The sliding base of this specially design fixture allows us to fix the base block and the bone at any location on the lower base plate. The bone can be fastened at any location on the plate by sliding the upper block and bottom base together. A variety of moments can be created by altering the position of the bone. The techniques for specimen preparation, fixture manufacture, testing, and result evaluation are outlined. Under diverse surgical settings, several porcine specimens have been successfully tested. Finally, the designed fixture's efficacy is assessed by comparing the outcomes obtained under various surgical situations.
