Nancy E Epstein
BACKGROUND: Minimally invasive surgery (MIS) spine procedures were developed to limit operative time, the extent of dissection, and reduce perioperative morbidity. Here, we asked what are the "learning curves" for these MIS spine procedures? METHODS: We reviewed studies in the literature that discussed the "learning curves" attributed to performing different MIS spine surgical procedures. Of interest, the majority were single-surgeon series. RESULTS: Very few articles assessed the learning curves for different MIS spine procedures...

Lumbar fusion is a surgical procedure performed to eliminate painful motion in a spinal segment by joining, or fusing, two or more vertebrae. Although the surgery has a high rate of producing radiographic fusion, many patients report pain, functional disability, an inability to return to work, and prolonged opioid pain reliever use following the procedure. Using the biopsychosocial model of low back pain as a framework, this review of the literature describes the biological, psychological, and social factors that have been associated with these negative outcomes...

BACKGROUND: Both unilateral pedicle screw fixation with posterior lumbar interbody fusion (PLIF) and bilateral pedicle screw fixation with PLIF are used to treat lumbar degenerative diseases (LDD). However, which one is a better treatment for LDD remains considerable controversy. Therefore, the focus of this meta-analysis was to assess the merits and shortcomings of efficacy of these 2 surgical procedures for LDD. METHODS: An extensive search of literature was performed in Pubmed/MEDLINE, Embase, CNKI, and WANFANG databases on unilateral versus bilateral pedicle screw fixation with PLIF fusion for LDD, from January 2007 to January 2017 and language was restricted to Chinese or English...

The conventional location methods for minimally invasive spinal surgery (MISS) were mainly based on repeated fluoroscopy in a trial-and-error manner preoperatively and intraoperatively. Localization system mainly consisted of preoperative applied radiopaque frame and intraoperative guiding device, which has the potential to minimize fluoroscopy repetition in MISS. The study aimed to evaluate the efficacy of a novel lumbar localization system in reducing radiation exposure to patients.Included patients underwent minimally invasive transforaminal lumbar interbody fusion (MISTLIF) or percutaneous transforaminal endoscopic discectomy (PTED)...

BACKGROUND: Our previous study demonstrated that selective nerve root block (SNRB) can influence decision-making in lumbar surgery by guiding the selection of nerve roots targeted for decompression in diagnostic doubt patients (DDPs). However, further studies were needed to determine whether this selective decompression (SD) procedure would result in similar clinical outcomes and reduce the perioperative parameters and postoperative complications as compared to the non-selective decompression (NSD) procedure...

Timothy L T Siu, Kainu Lin
Due to the obstruction of the iliac crest and the retroperitoneal vessels, lateral lumbar interbody fusion (LLIF) is generally considered contraindicated at the lumbosacral junction (LSJ). In particular the 'rise' of the psoas from the vertebral column in the lower lumbar segments has been associated with significant overlap of the lumbar plexus with the vertebral body and exclusion of a safe transpsoas entry. However in selected individuals anatomical variations may help circumvent the difficulties and the anatomical corridor posterior to the lumbar plexus may provide an alternative to the conventional anterior approach...

BACKGROUND: Extreme lateral interbody fusion (ELIF) has gained popularity as minimally invasive technique for indirect decompression. However, graft subsidence potentially threatens the long-term success of ELIF. The aim of the study was to evaluate whether 26mm wide cages can eliminate subsidence and subsequent loss of decompression in ELIF. METHODS: Patients undergoing ELIF surgery using a 26mm wide cage were analyzed retrospectively. Patient demographics and peri-operative data for radiographic and clinical outcomes were recorded...

PURPOSE: To evaluate the influence of a nonrigid fixation system and posterior lumbar interbody fusion on adjacent intervertebral disc degeneration by using MRI analysis of lumbar nucleus pulposus volume for single-level lumbar disc herniation. MATERIALS AND METHODS: We selected 112 patients who underwent nonrigid fixation (17 men and 44 women) or posterior lumbar interbody fusion (13 men and 38 women) for this retrospective study. Based on the T2-weighted magnetic resonance imaging (MRI) scans taken preoperatively, and 6, 12, and 24 months after surgery, the nucleus pulposus in the upper segments of the operated level was considered an ellipsoid, and their volumes were measured respectively and then compared between the two groups...

Pseudogout is a form of acute calcium pyrophosphate deposition (CPPD) disease that typically afflicts the elderly. CPPD commonly involves larger joints, such as the knees, wrists, shoulders, and hips, and has been known to involve the spine. The authors report the case of a 66-year-old woman with a recent history of lumbar laminectomy and fusion who presented 5 weeks postprocedure with a clinical and radiographic picture consistent with multilevel skip lesions involving the cervical and thoracic spine, thoracic discitis, and epidural abscess...

BACKGROUND CONTEXT: Proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) are common problems after long segment (>5 levels) thoracolumbar instrumented fusions in the treatment of adult spinal deformity (ASD). No specific surgical strategy has definitively been shown to lower the risk of PJK as the result of a multifactorial etiology. PURPOSE: To assess the incidence of PJK and PJF in patients treated with prophylactic polymethylmethacrylate(PMMA) cement augmentation at the uppermost instrumented vertebrae(UIV) and rostral adjacent vertebrae(UIV+1)...
