A 65-year-old male originally had surgery for spondylolisthesis at L5-S1 in 2008 and then went on to have an L4-5 transforaminal lumbar interbody fusion (TLIF) with pedicle screw fixation from L4 to S1 and interbody graft in 2010. Despite having two surgical procedures, he continued with intractable back pain and was told he had a failed lumbar fusion. When he was evaluated with a computerized tomography (CT) scan from April 2015, it demonstrated an erosive nonunion of the L4-5 interbody fusion without incorporation of the polyetheretherketone (PEEK) cage...

BACKGROUND: Lumbar disc herniation is a major cause of back pain and sciatica. The surgical management of lumbar disc prolapse has evolved from exploratory laminectomy to percutaneous endoscopic discectomy. Percutaneous endoscopic discectomy is the least invasive procedure for lumbar disc prolapse. The aim of this study was to analyze the clinical outcome, quality of life, neurologic function, and complications. MATERIALS AND METHODS: One hundred patients with lumbar disc prolapse who were treated with percutaneous endoscopic discectomy from May 2012 to January 2014 were included in this retrospective study...

BACKGROUND AND PURPOSE: Flat panel catheter angiotomography performed during the selective injection of intersegmental arteries offers a multiplanar assessment of the intraforaminal course of the radicular arteries providing an anterior radiculomedullary artery. Injury of anterior radiculomedullary arteries during transforaminal epidural steroid injections can result in spinal cord damage. Evaluations of the intraforaminal location of these arteries have so far been limited to anteroposterior views or the examination of cadaveric material...

INTRODUCTION: Dural breaches have a diverse etiology, including spontaneous rupture and trauma. Most cases resolve with bedrest, though in refractory cases an epidural blood patch can be placed to obstruct further leakage. Here, we discuss a unique case of a spontaneous ventral durotomy following vaginal delivery managed with injections of autologous blood through bilateral transforaminal needles. CLINICAL PRESENTATION: A previously healthy 36-year-old pregnant female presented to the inpatient maternity ward with positional occipital headaches and neck pain 24 hours following normal spontaneous vaginal delivery...

OBJECTIVE: Postdural puncture headache (PDPH) is an uncommon sequel of lumbar puncture in children. When conservative treatment with bed rest, hydration, and caffeine are ineffective, epidural blood patches are recommended and are generally effective. The purpose of this report was to highlight that when lumbar epidural blood patches fail to eliminate PDPH, diagnostic evaluation should be performed and alternative treatment sought. CASE REPORT: An unusual case is described of an 11-year-old boy with PDPH, which was successfully managed with a ventral (anterior) epidural blood patch and epidural saline infusion after headache and other symptoms failed to resolve after conservative treatment and conventionally performed blood patches...

BACKGROUND: Minimally invasive spine surgery (MISS) has been increasingly advocated during the last decade with new studies being reported every year. Minimally invasive spine procedures, such as minimally invasive transforaminal interbody fusion (MI-TLIF), have been introduced to reduce approach-related muscle trauma, to minimise blood loss, and to achieve faster wound healing, quicker ambulation and earlier patient discharge. METHODS: The aim of this article was to give a comprehensive review of the available English literature comparing open TLIF with MI-TLIF techniques published or available online between 1990 and 2014 as identified by an electronic database search on http://www...

BACKGROUND: Minimally invasive surgery (MIS) technique is becoming the standard tissue sparing approach for decompression of lumbar central and lateral recess stenosis, intervertebral disc herniation, or any situation that would have required extensive open decompression laminectomy. Full-endoscopic or arthroscopic assisted surgery is arguably the "ultra-MIS" approach to lumbar spinal pathology. Age and body mass index (BMI) are significant risk factors to be considered in full-endoscopic assisted ultra-MIS...

BACKGROUND: Patients who experience percutaneous endoscopic lumbar discectomy (PELD) recurrence need to undergo revision surgery when they fail to respond to conservative therapy. Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), microendoscopic discectomy (MED) and PELD are three common minimally invasive surgical approaches for PELD recurrence. However, there have been no studies that have focused on the selection of the minimally invasive surgical method for PELD recurrence...
