Early Fusion Status after Posterior Lumbar Interbody Fusion with Cortical Bone Trajectory Screw Fixation: A Comparison of Titanium-Coated Polyetheretherketone Cages and Carbon Polyetheretherketone Cages.

Asian Spine J 2018 Nov 29. Epub 2018 Nov 29.

Department of Orthopaedic Surgery, Kansai Rosai Hospital, Amagasaki, Japan.

Study Design: Retrospective cohort study.

Purpose: We recently reported that when compared to posterior lumbar interbody fusion (PLIF) using traditional pedicle screw fixation, PLIF with cortical bone trajectory screw fixation (CBT-PLIF) provided favorable clinical outcomes and reduced the incidence of symptomatic adjacent segment pathology, but resulted in relatively lower fusion rates. Since titanium-coated polyetheretherketone (PEEK) cages (TP) could improve and accelerate fusion status after CBT-PLIF, early fusion status was compared between CBT-PLIF using TP and carbon PEEK cages (CP).

A novel technique for stabilization of high-grade spondylolisthesis with transvertebral fusion without reduction.

J Clin Neurosci 2018 Nov 20. Epub 2018 Nov 20.

University of Miami Hospital, Department of Orthopaedic Surgery, 1400 N.W. 12th Ave, Miami, FL 33136, United States.

Surgical treatment of high-grade spondylolisthesis and spondyloptosis is recommended in symptomatic patients, yet there exists much debate regarding the optimal surgical approach and the need for reduction. Similar to the Bohlman technique in that fixation is achieved across two vertebral endplates, we discuss a novel technique with the advantage of using bilateral threaded pedicle screws of large diameter and length instead of a single fibula allograft. Patients underwent posterior instrumented fusion without spondylolisthesis reduction using a novel technique placing pedicle screws with a transvertebral trajectory through the two end plates involved in the spondylolisthesis.

High Sacral Endplate Inclination Vector Forces Are Associated with Pars Fracture-Mediated Lumbosacral Spondylolisthesis.

World Neurosurg 2018 Nov 1. Epub 2018 Nov 1.

Department of Neurosurgery, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Objective: Lumbar spondylolisthesis can be related to facet arthropathy and disc degeneration or to a fracture of the pars interarticularis, but the mechanistic underpinnings of spondylolisthesis remain unclear. We posit that high sacral slope and body weight increase sacral inclination vector forces, which leads to pars fractures and exacerbates risk for spondylolisthesis.

Methods: To investigate this hypothesis, we measured the sacral slope, body weight, and S1 endplate vector forces for patients who underwent L5-S1 fusion for grade I spondylolisthesis. Read More

Simultaneous lateral interbody fusion and pedicle screws (SLIPS) with CT-guided navigation.

Clin Neurol Neurosurg 2018 Dec 23;175:91-97. Epub 2018 Oct 23.

Department of Neurosurgery, Baylor College of Medicine, Houston, Texas, USA. Electronic address:

Objectives: The advent of minimally invasive, percutaneous techniques for the placement of pedicle screws has led to the evolution of a popular treatment paradigm: anterior or lateral interbody fusions followed by posterior percutaneous pedicle screw placement. We present the operative technique for anterior-to-psoas lateral interbody fusion (ATP-LIF) with simultaneous posterior lumbar percutaneous pedicle screw fixation using intraoperative CT-guided navigation.

Patients And Methods: This technique capitalizes both on the more oblique approach used in the ATP-LIF procedure, as well as the anatomic clarity gleaned from intraoperative CT-guided navigation, to allow for simultaneous placement of pedicle screws in the lateral position without the need for guiding fluoroscopy.

Background: When conservative treatments fail to alleviate the discomfort of abnormal motion, spinal fusion has been shown to provide symptomatic treatment for spinal instability, stenosis, spondylolisthesis, and symptomatic degenerative disc disease. The trend and rates of fusion over the past few years have been dramatic in the United States. Accompanying that higher incidence has been the shifting from traditional open surgery to minimally invasive techniques to reduce scar tissue formation, extent of muscle stripping, and muscle retraction which all have been shown to adversely affect outcomes.

Spinal Stenosis in the Absence of Spondylolisthesis: Can Interlaminar Stabilization at Single and Multi-levels Provide Sustainable Relief?

Int J Spine Surg 2018 Jan 30;12(1):64-69. Epub 2018 Mar 30.

Hospital for Special Surgery, New York, NY, USA.

Background: In the absence of spondylolisthesis, fusion procedures are generally not recommended. However, decompression alone often does not provide long-term clinical success of intractable leg and back pain. Decompression with interlaminar stabilization (ILS) offers a new option within the clinical continuum of care by providing a nonfusion surgical alternative. Read More

Degenerative Lumbar Spondylolisthesis: Biochemical Aspects and Evaluation of Stabilization Surgery Extent in Terms of Adjacent Segment Disease Theory.

World Neurosurg 2018 Sep 29. Epub 2018 Sep 29.

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.

Transforaminal Endoscopic Decompression of the Lumbar Spine for Stable Isthmic Spondylolisthesis as the Least Invasive Surgical Treatment Using the YESS Surgery Technique.

Int J Spine Surg 2018 Jun 15;12(3):408-414. Epub 2018 Aug 15.

Spine Unit, Orthopedic Department, Queen Savang Vadhana Memorial Hospital, Sri Racha, Chonburi, Thailand.

The first author's series has reported and published his 5- to 10-year results in a preliminary review of endoscopic transforaminal decompression for degenerative and isthmic spondylolisthesis causing sciatica and back pain. This study was initiated due to favorable results in relieving both back and leg pain after a spine surgeon with isthmic spondylolisthesis who wanted to avoid fusion requested consideration for an endoscopic procedure for his own isthmic spondylolisthesis condition. After listening to the first author's podium presentation on selective endoscopic discectomy and foraminal decompression under local anesthesia in 1995, he requested consideration for transforaminal endoscopic decompression for recent onset of progressive sciatica from his isthmic spondylolisthesis.

Long-Term Experience With Reduction Technique in High-Grade Spondylolisthesis in the Young.

Int J Spine Surg 2018 Jun 15;12(3):399-407. Epub 2018 Aug 15.

Apollo Hospitals, Chennai, India.

Background: Surgical management of high-grade spondylolisthesis in the young is not only challenging but also controversial, from in-situ fusion to complete reduction. It is fraught with dangers such as neurological injury, pseudoarthrosis, and progressive deformity with subsequent global sagittal imbalance. We describe our experience of progressive reduction technique and restoration of lumbosacral alignment. Read More

Anterior Lumbar Interbody Fusion With Cement Augmentation Without Posterior Fixation to Treat Isthmic Spondylolisthesis in an Osteopenic Patient-A Surgical Technique.

Int J Spine Surg 2018 Jun 15;12(3):322-327. Epub 2018 Aug 15.

Washington Spine and Scoliosis Clinic, OrthoBethesda, Bethesda, Maryland.

Background: Anterior lumbar interbody fusion (ALIF) has been well established as an effective surgical intervention for chronic back pain due to osteoporotic vertebral collapse. Historically, ALIF has consisted of an anterior approach to disc height restoration with a subsequent posterior pedicle screw fixation. Although the applications of cement augmentation with posterior fixation have been previously reported, treatment of patients with both isthmic spondylolisthesis and decreased bone mineral density using a stand-alone ALIF is controversial because of concerns for decreased fusion rates and increased subsidence risk, respectively.
