Qing Yue, Tyson Hale, Aaron Knecht, Jennifer Laidacker
BACKGROUND: Foot drop secondary to L5 root injury is a rare complication associated with lumbar surgery. To date, it is still not clear whether intraoperative neuromonitoring can detect such an injury. CASE DESCRIPTION: A 54-year-old man who had had bilateral chronic L5 radiculopathy underwent L4-S1 lumbosacral decompression and fusion. During the surgery, the patient lose transcranial electrical motor evoked potential (tceMEPs) from left tibialis anterior (TA) at the time of L5-S1 intervertebral cage placement...

OF BACKGROUND DATA: Degenerative changes including Modic Changes (MCs) are commonly observed in patients with chronic low back pain. Although intervertebral disc (IVD) cytokine expression has been shown to be associated with low back pain, the cytokine profile for degenerative IVD with and without MC has not been compared. PURPOSE: To evaluate the potential association between intervertebral disc cytokine expression and MCs. STUDY DESIGN: Laboratory Study METHODS: The IVD from ten patients with Type II MCs and ten patients without MCs who underwent an anterior lumbar interbody and fusion for significant low back pain were collected...

BACKGROUND: Low back pain and degeneration of the intervertebral disc are an integrated malady that affects millions of Americans. Cage devices used in association with posterior lumbar interbody fusion (PLIF) have been shown to be an effective approach in the treatment of a number of lower spine disorders attributed to degenerative disc disease (DDD). OBJECTIVE: This study was undertaken as part of a U.S. Food and Drug Administration (FDA) Investigational Device Exemption (IDE) study and compares the effectiveness of the Asfora Bullet Cage System (ABCS) to successfully fuse vertebra at one or two levels between L2 and S1 in patients with DDD to an FDA approved comparison device, the Medtronic-Sofamor Danek Inter Fix Threaded Fusion Device (MSDIFD)...

BACKGROUND CONTEXT: A variety of surgical approaches have been used for cage insertion in lumbar interbody fusion surgery. The direct anterior approach requires mobilization of the great vessels to access the intervertebral disc spaces cranial to L5/S1. With the lateral retroperitoneal transpsoas approach, it is difficult to access the L4/L5 intervertebral disc space due to the lumbar plexus and iliac crest, and L5/S1 is inaccessible. We describe a new anterolateral retroperitoneal approach, which is safe and reproducible to access the disc spaces from L1 to S1 inclusive, obviating the need for a separate direct anterior approach to access L5/S1...

OBJECTIVE: Anterior lumbar interbody fusion (ALIF) is a common procedure used to treat various lumbar degenerative pathologies. The purpose of this study is to describe 30-day postoperative outcomes following ALIF on a national scale. METHODS: The American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) was searched for ALIF patients between 2005 and 2011. The top preoperative diagnoses were determined using ICD-9 codes. All available 30-day complications were grouped as overall composite morbidity and were compared between preoperative diagnosis groups by univariable and multivariable analyses...

This study investigated the biomechanical response of porous cages and lumbar spine segments immediately after surgery and after bone fusion, in addition to the long-term effects of various posterior lumbar interbody fusion (PLIF) techniques, by using the finite element method. Lumbar L3-L4 models based on three PLIF techniques (a single cage at the center of the intervertebral space, a single cage half-anterior to the intervertebral space, and two cages bilateral to the intervertebral space) with and without bone ingrowth were used to determine the biomechanical response of porous cages and lumbar segments instrumented with porous titanium cages (cage porosity=50%, pore diameter=1mm)...

INTRODUCTION: The modern literature is producing a rapidly growing number of articles which highlight the relationship between infection and lumbar disc degeneration. However, the means by which samples are collected is questionable. Posterior approach surgery is not free from skin contamination. The possibility of intraoperative contamination of disc biopsies cannot be excluded. OBJECTIVE: The objective of this study was to determine if an association existed between lumbar disc degeneration and chronic infection of the intervertebral disc...

Update on pathologies of adult spinal deformity (ASD): With advancement of aging society, ASD has become one of the most notable topics of spinal disorders owing to its significant impact on health related quality of life. Treatment for ASD is challenging due to complex nature of deformity and high prevalence of comorbidities. Spino-pelvic harmony that is evaluated by pelvic incidence (PI) minus lumbar lordosis (LL) is the most important concept, which allows us to understand pathology of ASD more deeply. Proposed optimum "PI minus LL" is within ±10°...

The lateral lumbar interbody fusion (LLIF) is a relatively new technique that allows the surgeon to access the intervertebral space from a direct lateral approach either anterior to or through the psoas muscle. This approach provides an alternative to anterior lumbar interbody fusion with instrumentation, posterior lumbar interbody fusion, and transforaminal lumbar interbody fusion for anterior column support. LLIF is minimally invasive, safe, better structural support from the apophyseal ring, potential for coronal plane deformity correction, and indirect decompression, which have has made this technique popular...
