摘要: Low back pain is one of today's most common health problems. Fusion surgery may be considered when pain persists and conservative treatments fail to provide relief in a patient with degenerative disc disease [1]. One of the most successful fusion approaches, with success rates up to 97%, is the anterior lumbar interbody fusion (ALIF)[2]. After removal of the affected intervertebral disc, an angle and height variable cage is placed between the cranial and caudal vertebral bodies. The global lumbar lordosis (LL) is patient-specific and affected by the cage lordosis (CL) choice. To reduce the probability of progress of adjacent segment diseases, the reconstruction of a physiological LL is essential in this regard [3]. In the light of customary discrete CL decisions of stand-alone ALIF, this simulative study investigates biomechanical effects of L4-L5 CL variances on adjacent spinal structures.
