BACKGROUND: There are various techniques and approaches for lumbar interbody fusion differing in access, cage type and type of supplemental posterior instrumentation. While a transforaminal access usually includes a hemifacetectomy, the facet joint can be preserved with a more lateral extraforaminal access. The supplemental posterior instrumentation required for both fusion techniques is still debated. The purpose of the present study was to compare primary stability of the two accesses for two different cage types with none, unilateral and bilateral supplemental posterior instrumentation...

Posttraumatic deformities after vertebral fractures are challenging for orthopedic surgeons in the non-operative and operative field. Especially osteoporotic fractures may cause a hyperkyphosis resulting in segmental or global sagittal imbalance and chronic back pain. Different vertebral osteotomies are potent to restore sagittal profile but show a very high perioperative risk including neurological and soft tissue complications. In addition, some of these extensive operations require a two-step procedure including posterior and anterior approaches...

BACKGROUND: Transforaminal endoscopic lumbar discectomy (TELD), a minimally invasive spinal technique, has advantages over open discectomy. Unilateral TELD for disc herniation causing bilateral symptoms is challenging. In this study, we describe a percutaneous endoscopic herniotomy technique by using a unilateral approach for lumbar disc herniation with bilateral obvious symptoms. METHODS: From June 2014 to October 2015, 26 patients who had back as well as bilateral leg pain and/or weakness due to lumbar disc herniation were treated by transforaminal endoscopic lumbar discectomy (TELD) with a unilateral approach...

OBJECTIVE: The purpose of this study was to assess the feasibility of minimally invasive transforaminal lumbar interbody fusion (TLIF) and bilateral decompression via a unilateral approach that was performed with a novel working retractor with an endoscopic system for degenerative lumbar spondylolisthesis associated with spinal stenosis, to minimize surgical trauma without compromising the quality of the treatment outcome. METHODS: In this case series, the procedure was performed in 17 patients...

BACKGROUND: Spinal brucellosis is a less commonly reported infectious spinal pathology. There are few reports regarding the surgical treatment of spinal brucellosis in existing literature. This retrospective study was conducted to determine the effectiveness of single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation for lumbosacral spinal brucellosis. METHODS: From February 2012 to April 2015, 32 consecutive patients (19 males and 13 females, mean age 53...

Symptomatic spondylolisthesis patients may benefit from surgical decompression and stabilization. The standard (S) technique is a transforaminal lumbar interbody fusion (TLIF). Newer, minimally invasive (MI) techniques seem to provide similar results with less morbidity. We enrolled patients with at least 6 months of symptoms and image-confirmed low-grade spondylolisthesis, at a single academic institution, between 2011 and 2015. The patients were randomized to either S or MI TLIF. The primary outcome measure was the Oswestry Disability Index (ODI) improvement at 1 year...

BACKGROUND: Sagittal rebalancing of a fixated lumbar hypolordosis (kyphosis) is very important to gain satisfactory results. To correct a misalignment vertebral column resection or pedicle subtraction osteotomies are favored, disregarding the relatively high complication rates. The aim of this study was to evaluate the efficiency and safety of a new modified transforaminal lumbar fusion technique as an alternative. METHODS: We conducted a retrospective review (06/2011-06/2015 ) of a prospective database at an University hospital...

OBJECTIVE: To explore the effect of percutaneous transforaminal endoscopic discectomy under different anesthesia on pain and immunity of patients with lumbar disc herniation. PATIENTS AND METHODS: 92 cases of patients with lumbar disc herniation in the Affiliated Hospital of Qingdao University from February 2015 to January 2016 were collected. These patients were randomly divided into control group and observation group (n = 46). Patients in the control group underwent percutaneous transforaminal endoscopic discectomy with the use of local anesthesia, while patients in the observation group used continuous epidural anesthesia...

BACKGROUND: Studies have shown that a significant learning curve may be associated with adopting minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) with bilateral pedicle screw fixation (BPSF). Accordingly, several hybrid TLIF techniques have been proposed as surrogates to the accepted BPSF technique, asserting that less/fewer fixation(s) or less disruptive fixation may decrease the learning curve while still maintaining the minimally disruptive benefits. TLIF with interspinous process fixation (ISPF) is one such surrogate procedure...

INTRODUCTION: Lumbar interbody fusions have been widely used to treat degenerative lumbar disease that fails to respond to conservative treatment. This procedure is divided according to its approach: anterior lumbar interbody fusion (ALIF), posterior lumbar interbody fusion (PLIF), transforaminal lumbar interbody fusion (TLIF) and lateral lumbar interbody fusion (LLIF). Each approach has its own theoretical advantages and disadvantages; however, there have been no studies that compared these...

METHODS: This study is a retrospective analysis of 76 patients who underwent MI-TLIF between April 2012 and June 2016. Group A consisted of 35 patients (< 65 years) while Group B consisted of 41 patients (≥ 65 years). Intraoperative data were recorded. The evaluation of clinical outcomes was based on the Visual Analog Scale for back and leg pain and the Oswestry Disability Index...

BACKGROUND: Retinal artery occlusion (RAO) is a rare but devastating complication of spinal fusion surgery. We aimed to determine its incidence and associated risk factors. METHODS: Hospitalizations involving spinal fusion surgery were identified by searching the National Inpatient Sample, a database of hospital discharges, from 1998 to 2013. RAO cases were identified using ICD-9-CM codes. Using the STROBE guidelines, postulated risk factors were chosen based on literature review and identified using ICD-9-CM codes...

Transforaminal epidural steroid injection (TFESI) is a minimally invasive modality used to treat patients with lumbosacral radiculopathy secondary to prolapsed intervertebral disc or spinal canal stenosis. In this case report, we describe the management of a patient with chronic lumbosacral radiculopathy secondary to intervertebral disc herniation which was seen as a right paracentral disc protrusion at levels L4-L5, L5-S1 causing thecal sac indentation, effacement of the right lateral recess and right exiting nerve root impingement as was seen on the magnetic resonance image...

AIMS: Minimally invasive transforaminal lumbar interbody fusion (MITLIF) has been well validated in overweight and obese patients who are consequently subject to a higher radiation exposure. This prospective multicentre study aimed to investigate the efficacy of a novel lumbar localisation system for MITLIF in overweight patients. PATIENTS AND METHODS: The initial study group consisted of 175 patients. After excluding 49 patients for various reasons, 126 patients were divided into two groups...

Image-guided approaches to spinal instrumentation and interbody fusion have been widely popularized in the last decade [1-5]. Navigated pedicle screws are significantly less likely to breach [2, 3, 5, 6]. Navigation otherwise remains a point reference tool because the projection is off-axis to the surgeon's inline loupe or microscope view. The Synaptive robotic brightmatter drive videoexoscope monitor system represents a new paradigm for off-axis high-definition (HD) surgical visualization. It has many advantages over the traditional microscope and loupes, which have already been demonstrated in a cadaveric study [7]...

Typical sources for graft material utilized in minimally invasive transforaminal lumbar interbody fusion include both autograft and allograft. Autograft is frequently utilized due to its theorized benefits in promoting fusion. During minimally invasive transforaminal lumbar interbody fusion, autograft is often obtained locally during the laminectomy and facetectomy. However, this locally obtained bone graft has exhibited questionable osteoconductive properties, often necessitating the addition of biologics to improve fusion rates...
