Abstract
This study provides evidence that the base-facet foraminoplasty of L5 superior facet provided a higher segmental stability compared with the tip-facet foraminoplasty in flexion and axial rotation. Meanwhile, it also shows the two types of foraminoplasty make few differences to the L4/5 segmental biomechanics. Besides, it does not appear to impact the stability of L3 /L4 in six states of forward flexion, backward extension, left lateral bending, right lateral bending, left axial rotation and right axial rotation when superior facet of L5 was partially removed. These findings might be useful in understanding biomechanics of the lumbar spine after foraminoplasty performed on different portions of the facet, thus providing endoscopic surgeons a better reference for operational approach to maintain the function and mobility of the spine.
