BACKGROUND: Almost every surgical approach carries the risk to cause some degree of spinal instability, especially in case of excessive resection of the lamina and facet joint. This study describes the endoscopic intralaminar approach (ILA) for the treatment of cranially and caudally migrated lumbar disc herniation. METHODS: Thirty-one patients who underwent endoscopic ILA for 26 caudally and 5 cranially migrated lumbar disc herniation were identified from a prospectively database...

BACKGROUND: Decompression without fusion is a treatment option in patients with lumbar spinal stenosis (LSS) associated with stable low-grade degenerative spondylolisthesis (DS). A minimally invasive unilateral laminotomy (MIL) for "over the top" decompression might be a less destabilizing alternative to traditional open laminectomy (OL). OBJECTIVE: To review secondary fusion rates after open vs minimally invasive decompression surgery. METHODS: We performed a literature search in Pubmed/MEDLINE using the keywords "lumbar spondylolisthesis" and "decompression surgery...

Ha Son Nguyen, Sean Lew
INTRODUCTION: Laminectomy is the traditional approach for posterior exposure of the spinal canal for tumor resection. Another technique is split laminotomy, which entails the division and retraction of the spinous processes and laminae to access the thecal sac. This technique has been employed for small-segment exposures, but not extensively explored for long-segment exposures. CASE: A 2-month-old male presented with progressive right-leg plegia. MRI of the spine revealed a large, intramedullary spinal-cord lipoma extending from C6 to L5...

BACKGROUND: There are several posterior decompression techniques for lumbar spinal stenosis (LSS). There is a trend towards performing less invasive surgical procedures, but no multicentre randomized controlled trials have evaluated the relative efficacy of these techniques at short and long-term. METHOD/DESIGN: A multicentre randomized controlled trial [the Spinal Stenosis Trial (SST) (part of the NORDSTEN study)] including 465 patients aged 18-80 years with neurogenic claudication or radiating pain and MRI findings indicating lumbar spinal stenosis without spondylolisthesis is performed to compare three posterior decompression techniques: unilateral laminotomy with crossover, bilateral laminotomy and spinous process osteotomy...

STUDY DESIGN: A retrospective comparative series study. OBJECTIVE: The aim of the study was to describe a new angled chisel (NAC) that facilitates the osteotomy in microendoscopic decompressive laminotomy (MEDL), and to analyze the clinical and radiologic outcomes using the tool. SUMMARY OF BACKGROUND DATA: MEDL for lumbar spinal stenosis is a minimally invasive surgery. The paraspinous unilateral approach for bilateral decompression can preserve the posterior structure better than other methods...

OBJECTIVE Since the entity limited dorsal myeloschisis (LDM) was proposed, numerous confusing clinical cases have been renamed according to the embryopathogenesis. However, clinical application of this label appears to require some clarification with regard to pathology. There have been cases in which all criteria for the diagnosis of LDM were met except for the presence of a neural component in the stalk, an entity the authors call "probable" LDM. The present study was performed to meticulously review these cases and suggest that a modified surgical strategy using limited laminectomy is sufficient to achieve the surgical goal of untethering...

BACKGROUND: Several surgical variables and patient characteristics play an influential role in the prognosis of lumbar disc herniation following laminotomy with discectomy. This paper seeks to evaluate the perioperative predictor variables for the outcome of lumbar disc herniation. PATIENTS AND METHODS: From October 2013 to July 2016, 166 surgical patients were evaluated using prospectively collected data. Patients' preoperative independent variables (age, sex, body mass index, level of disc herniation, pain duration, and American Society of Anesthesiologists Physical Score) were correlated with functional outcome measures such as primary outcome measures (length of hospital stay; postoperative visual analog scale, VAS; Oswestry disability index, ODI) and secondary outcome measures (operation room time; estimated intraoperative blood loss, EBL; complications; readmission) as dependent variables...

Spinal schwannomas are commonly intradural extramedullary in location. As Schwann cells are not common in the central nervous system, intramedullary schwannomas are a rare entity. In adults, an estimated sixty cases have been reported in English literature. They are rarer in children (less than ten cases), and preoperative diagnosis becomes a prerogative in achieving total excision. Cervical cord is a common location and less commonly they occur in the conus. We report a rare case of calcified conus intramedullary schwannoma in a child without neurofibromatosis, who presented with conus-cauda syndrome of 1-year duration...

INTRODUCTION: The operating microscope (OM) has become instrumental in aiding surgeons during key microdissection with greater safety and detail. An exoscope offers similar detail with improved functionality and greater implications for live teaching and improved operating room flow. METHODS: Eleven senior neurosurgery residents and fellows performed unilateral, single-level laminotomies on fresh cadavers using an OM and exoscope. Three attending spine surgeons blinded for the visualization technique used then reviewed and graded each decompression...

Barrett S Boody, Jason W Savage
Lumbar facet cysts are a rare but increasingly common cause of symptomatic nerve root compression and can lead to radiculopathy, neurogenic claudication, and cauda equina syndrome. The cysts arise from the zygapophyseal joints of the lumbar spine and commonly demonstrate synovial herniation with mucinous degeneration of the facet joint capsule. Lumbar facet cysts are most common at the L4-L5 level and often are associated with spondylosis and degenerative spondylolisthesis. Advanced imaging studies have increased diagnosis of the cysts; however, optimal treatment of the cysts remains controversial...

Lumbar disk herniation (LDH) is a degenerative pathology. Although LDH generally occurs without migration of the fragment to the levels above or below, in 10% of the cases, this circumstance might happen. In these cases, the standard interlaminar approach, described by Caspar cannot be performed without laminotomies, interlaminectomies, or partial or total facetectomies. The translaminar approach is the only "tissue-sparing" technique viable in cases of cranially migrated LDH encroaching on the exiting nerve root in the preforaminal zones, for the levels above L2-L3, and in the preforaminal and foraminal zones, for the levels below L3-L4 (L5-S1 included, if a total microdiscectomy is unnecessary)...

BACKGROUND: Lumbar synovial cysts can result from spondylosis of facet joints. These cysts can encroach on adjacent nerve roots, causing symptoms of radiculopathy. Currently the only definitive treatment for these symptoms is surgery, which may involve laminectomy or laminotomy, with or without spinal fusion. Surgery has been reported to successfully relieve radicular pain in 83.5% of patients by Zhenbo et al. Little information is available concerning the efficacy and outcome of percutaneous fluoroscopic synovial cyst rupture for treatment of facet joint synovial cysts...

BACKGROUND: The basic necessities for surgical procedures are illumination, exposure, and magnification. These have undergone transformation in par with technology. One of the recent developments is the compact magnifying exoscope system. In this report, we describe the application of this system for surgical operations and discuss its advantages and pitfalls. METHODS: We used the ViTOM exoscope mounted on the mechanical holding arm. The following surgical procedures were conducted: lumbar and cervical spinal canal decompression (n = 5); laminotomy and removal of lumbar migrated disk herniations (n = 4); anterior cervical diskectomy and fusion (n = 1); removal of intraneural schwannomas (n = 2); removal of an acute cerebellar hemorrhage (n = 1); removal of a parafalcine atypical cerebral hematoma caused by a dural arteriovenous fistula (n = 1); and microsutures and anastomoses of a nerve (n = 1), an artery (n = 1), and veins (n = 2)...

BACKGROUND: Angiogliomas are rare low-grade glial tumors with significant vascular components. These tumors are usually seen in the brain, and spinal cord angiogliomas have not been reported in the literature until now. CASE DESCRIPTION: We report the case of a 15-year-old boy with an angioglioma of the medulla and cervicodorsal spine, which was completely excised through a combined suboccipital craniotomy and cervicodorsal laminotomy. The patient experienced excellent clinical recovery after the surgery, and follow-up contrast magnetic resonance imaging showed complete excision of the tumor...
