Lumbar spondylolysis is commonly recognized at a single-level of the lumbar spine and frequently affects the L5 pars interarticularis unilaterally or bilaterally. Some reports have described multiple-level spondylolysis, most cases of which occur at consecutive lumbar segments. We herein present a rare case of lumbar spondylolysis involving nonconsecutive multiple-level segments; only eight such cases have been reported previously. Read More

Department of Pharmacology, Jessenius Faculty of Medicine, Comenius University, Martin, Slovakia.

Objective: In lumbar degenerative spondylolisthesis (DSL), the criteria and extent of surgical treatment have not been strictly defined owing to the adjacent segment disease theory and unclear molecular pathogenesis. The present study analyzed the clinical and radiographic findings of patients after lower lumbar fusion surgery with single and 2-level DSL and explored the inflammatory mediator's role in DSL evolution and symptoms.

Methods: The prospective follow-up of patients with DSL, stratified by the stabilization extent (L4-L5, L5-S1, and L4-S1), included the Back Illness Pain and Disability 9-item questionnaire and native and dynamic radiographs to evaluate the intervertebral disc height and adjacent segments' angular motion.

Midline lumbar inter-body fusion (MIDLF) surgery with cortical bone trajectory (CBT) screw insertion is a modern fusion technique for spinal surgery. The difference in entry point of this trajectory from conventional pedicle screw surgery offers the potential benefits of less soft tissue dissection and reduced blood loss, post-operative wound pain, and infection risks. Because this is a newly developed technique first announced by Santoni in 2009, most surgeons perform this surgery in a mini-open fashion and require more intra-operative fluoroscopy and ionizing radiation exposure during screw placement.

High-grade dysplastic spondylolisthesis (HGDS) is a subset of L5-S1 spondylolisthesis that occurs due to dysmorphic anatomy at the lumbosacral junction, often resulting in sagittal imbalance. Enhanced understanding of global sagittal alignment has led many to preferentially treat HGDS with reduction and fusion to restore sagittal balance. The purpose of this article is to review published surgical techniques for obtaining sagittal correction in HGDS and to evaluate the current evidence regarding the associated surgical complications.

Alignment of the lumbar spine has an important impact on the segmental motion, degenerative pathology, and health-related quality of life. The relationship between lumbar lordosis and pelvic incidence is predictive in the pathogenesis of spinal disorders, including disk degeneration, spondylolisthesis, and adjacent segment degeneration. This article reviews the relationship between lumbar and pelvic alignment with pathology of the lumbar spine, provides goals for appropriate alignment in reconstructive surgery, and discusses strategies for effective realignment of the spine.

Long-construct fixations can be complicated by proximal junctional kyphosis. In elderly, high-risk patients with numerous comorbidities, lengthy surgical times and increased blood loss associated with revision osteotomies and extension of fusions are not often tolerated and pose serious life-threatening risks. We present a salvage technique used in a patient with proximal junctional failure and demonstrate its role in improving symptoms and functionality in those not deemed fit for major surgery.

Background: Spondylolytic (or lytic) spondylolisthesis is often associated with disc degeneration at the index-level; however, it is not clear if disc degeneration is the cause or the consequence of lytic spondylolisthesis. The main objective of this computed tomography based finite element modelling study was to examine the role of different grades of disc degeneration in the progression of a bilateral L5-lytic defect to spondylolisthesis.

Methods: High-resolution computed tomography data of the lumbosacral spine from an anonymised healthy male subject (26 years old) were segmented to build a 3D-computational model of an INTACT L1-S1 spine. Read More

Acquired spondylolysis represents an uncommon complication of spine surgery, of an unknown incidence and etiology. We studied patients presenting this rare entity, with the purpose to investigate the incidence, imaging findings, patients' clinical characteristics, as well as to provide an interpretation of the mechanisms that may lead to this phenomenon. The presented working hypothesis, regarding etiology, suggests that there is a relation between variations in spinopelvic sagittal alignment and acquired spondylolysis. Read More
