BACKGROUND: Arachnoid cysts of spine are a very rare occurrence. The aetiology still remains unclear, but the most accepted explanation is the existence of areas of weakness in the spinal dura. Symptoms depend on the location in the spine. Magnetic resonance imaging is used for its diagnosis. Management depends of clinical presentation, and the surgery is reserved for patients with neurological impairment. CLINICAL CASE: A case is described of 67 year-old male with myelopathy and radiculopathy symptoms, both diagnosed simultaneously...

The aim of this study was to directly compare the clinical outcomes of posterior lumbar interbody fusion (PLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in three-level lumbar spinal stenosis. This retrospective study involved a total of 60 patients with three-level degenerative lumbar spinal stenosis who underwent MIS-TLIF or PLIF from January 2010 to February 2012. Back and leg visual analog scale (VAS), Oswestry Disability Index (ODI), and Short Form-36 (SF-36) scale were used to assess the pain, disability, and health status before surgery and postoperatively...

Lumbar spinal stenosis is the most common reason for spinal surgery in Denmark. Lumbar spinal stenosis is a clinical syndrome of pain in the buttocks or lower extremities, with or without back pain. It is associated with reduced space available for the neural and vascular elements of the lumbar spine. The condition is often exacerbated by standing, walking or lumbar extension and relieved by forward flexion. The options for non-surgical management include drugs and physiotherapy. Treatment outcomes seem to be better for surgical neural decompression than for non-operative treatment...

OBJECTIVE Prior studies have shown obesity to be associated with higher complication rates but equivalent clinical outcomes following lumbar spine surgery. These findings have been reproducible across lumbar spine surgery in general and for lumbar fusion specifically. Nevertheless, surgeons seem inclined to limit the extent of surgery, perhaps opting for decompression alone rather than decompression plus fusion, in obese patients. The purpose of this study was to ascertain any difference in clinical improvement or complication rates between obese and nonobese patients following decompression alone compared with decompression plus fusion for lumbar spinal stenosis (LSS)...

BACKGROUND: Late-onset idiopathic aqueductal stenosis may present with clinical features indistinct from idiopathic normal-pressure hydrocephalus (NPH). Moreover, aqueductal stenosis (AS) is not always detected by conventional magnetic resonance imaging (MRI). The aim of this study was to compare the hydrodynamic pattern among NPH patients according to the patency of the aqueduct. METHODS: Fifty-six consecutive lumbar infusion tests were performed in patients with NPH syndrome...

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others...

BACKGROUND: The condition of paraspinal muscles is known to be associated with some variables such as age, gender, and low back pain. It is generally agreed that these muscles play an important role in the stability and functional movements of the lumbar vertebral column. Although spinal instability has been shown to play an essential role in degenerative lumbar spinal stenosis (DLSS), the role of paraspinal muscles remains elusive. The main purpose of this study was to shed light on the relationship between the condition of paraspinal muscles and symptomatic DLSS...

BACKGROUND: Minimal longitudinal data exist regarding the role of lumbar musculature in predicting back pain and function. In cross sectional study designs, there is often atrophy of the segmental multifidus muscle in subjects with low back pain compared with matched controls. However, the cross sectional design of these studies prevents drawing conclusions regarding whether lumbar muscle characteristics predict or modify future back pain or function. OBJECTIVE: The primary objective is to determine if the cross sectional area (CSA) of lumbar muscles predicts functional status or back pain at 6- or 12-month follow-up in older adults with spinal degeneration...

BACKGROUND: Percutaneous epidural neuroplasty with a Racz catheter is widely used to treat radicular pain caused by spinal stenosis or a herniated intervertebral disc. The breakage or shearing of an epidural catheter, particularly a percutaneous epidural neuroplasty catheter, is reported as a rare complication. There has been a controversy over whether surgical removal of a shorn epidural catheter is needed. Until now, only three cases related to sheared Racz neuroplasty catheters have been reported...

BACKGROUND: Intraforaminal disc herniations at the L5-S1 level are extremely surgically challenging lesions. Intracanal approaches frequently require partial or total facetectomy, which may lead to instability. Solely extraforaminal approaches may offer limited visualization of the more medial superiorly exiting and inferiorly exiting nerve roots; this approach is also more complicated at L5-S1 due to the often large L5 transverse process and the iliac wing. METHODS: Nine patients with intraforaminal L5-S1 disc herniations, foraminal stenosis, or synovial cysts underwent contralateral interlaminar approaches for lesion resection...

BACKGROUND AND PURPOSE: Slice-Encoding Metal Artifact Correction (SEMAC) sequence is one of the metal artifact reduction techniques of anatomical structure, but there has been no report about evaluation of post-operative complications. The purpose of this article is to compare the anatomical visibility between fast spin echo (FSE) and FSE-SEMAC and to evaluate the additional value of FSE-SEMAC in diagnostic confidence of the complications. MATERIALS AND METHODS: We conducted a retrospective study with 54 patients who received lumbar spinal surgery and MR images including FSE-SEMAC...

Spinal stenosis and low-grade spondylolisthesis produce symptoms of neural compression that can be treated with extreme lateral lumbar interbody fusion (XLIF) via indirect decompression. This study aimed to investigate whether the restoration of disc dimensions would relieve symptoms of radiculopathy, claudication and back pain. In this retrospective study, patients undergoing XLIF surgery for relief of radicular symptoms or degenerative disc disease were included. Radiologically proven changes were used to assess the modes of degeneration...

BACKGROUND: Interspinous spacers are used in selected patients for the treatment of lumbar spinal stenosis. The uses of interspinous devices are still debated, with reports of significantly higher reoperation rates and unfavourable cost-effectiveness compared to traditional decompression techniques. METHODS: Six electronic databases were searched from their date of inception to December 2015. Relevant studies were identified using specific eligibility criteria and data was extracted and analyzed based on predefined primary and secondary endpoints...
