Background: Adjacent segment disease (ASD) is a notable complication following lumbar fusion. Clinicians use various surgical techniques to correct progression of spine deterioration and reduce the risk of continued ASD. The aim of this retrospective case series is to describe patient outcomes following posterior lumbar interbody fusion (PLIF) using the VariLift® standalone expandable interbody...

BACKGROUND This prospective study analyzes the perioperative outcomes and long-term fusion success of 100 consecutive lumbar degenerative cases. The cases were managed using a non-threaded locking screw system, in conjunction with polyetheretherketone (PEEK) cages, for posterior lumbar interbody fusion (PLIF) procedures. These 100 cases were compared to another prospective study treating patien...

INTRODUCTION The goal of lumbar spinal fusion is to limit pain by decompression and removal of soft tissues, followed by the formation of a rigid bony union between adjacent vertebrae. The general consensus for a rigid fusion construct requires careful preparation of the intervertebral space and the creation of a rigid fusion construct. Anterior lumbar interbody fusion (ALIF) provides good acce...

BACKGROUND CONTEXT Stand-alone nonbiologic interbody fusion devices for the lumbar spine have been used for interbody fusion since the early 1990s. However, most devices lack the stability found in clinically successful circumferential fusion constructs. Stability results from cage geometry and device/vertebral endplate interface integrity. To date, there has not been a published comparative bi...

simple. dependable. proven. Abstract: The treatment of adjacent level disease subsequent to lumbar fusion often involves a particularly complex and invasive surgical procedure. This case report demonstrates that the stand-alone VariLift-L Expandable Interbody Fusion Device can provide a straight-forward and clinically successful solution for these patients. Treatment of Adjacent Level Disease w...

BACKGROUND Selecting an interbody cage with appropriate height is one of the key steps in lumbar interbody fusion, and has an important impact on clinical efficacy. How to choose the appropriate height of the cage becomes one of the core problems of lumbar interbody fusion for spine surgeons. However, studies about objective selection criteria on interbody cage height was rare. METHODS One hu...

The aim of this study was to compare the clinical efficacy between transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF) in treatment of lumbar spondylolisthesis. A total of 62 patients with lumbar spondylolisthesis were treated at our hospital from 2010 to 2013. These patients were divided into a TLIF group that included 36 patients (mean age: 60 years) and...

Study Design A retrospective clinical case series. Purpose To determine the strength of association between cage retropulsion and its related factors. Overview of Literature Lumbar interbody fusion with cage can obtain a firm union and can restore the disc height with normal sagittal and coronal alignment. Although lumbar interbody fusion procedures have satisfactory clinical outcomes, peri...

Spinal fusion historically has been used extensively, and, recently, the lateral transpsoas approach to the thoracic and lumbar spine has become an increasingly common method to achieve fusion. Recent literature on this approach has elucidated its advantage over more traditional anterior and posterior approaches, which include a smaller tissue dissection, potentially lower blood loss, no need f...

BACKGROUND Historically, iliac crest bone graft has been used as the graft of choice for lumbar spine fusion procedures. Because fusion techniques have become less invasive, the demand for minimally disruptive grafting options has increased. This prospective study was performed to assess clinical and radiographic outcomes of patients treated with an iliac crest bone graft alternative and latera...
