STUDY DESIGN: Survey. OBJECTIVE: To define the critical elements of common spine surgeries. SUMMARY OF BACKGROUND DATA: Despite significant relevance to the field of spine surgery, the term "critical element" of surgery has not been clearly defined. Every surgical procedure involves numerous steps, each with its own potential for complications and harm to the patient. Despite its crucial role in surgical training, billing, and the ethicality of concurrent surgery, the term "critical element" of surgery has not been defined...

BACKGROUND: Lumbar spinal stenosis is the most common indication for spine surgery in older adults. Interspinous process decompression (IPD) using a stand-alone spacer that functions as an extension blocker offers a minimally invasive treatment option for intermittent neurogenic claudication associated with spinal stenosis. METHODS: This study evaluated the 5-year clinical outcomes for IPD (Superion(®)) from a randomized controlled US Food and Drug Administration (FDA) noninferiority trial...

BACKGROUND: Parkinson's disease (PD) is a major risk factor during spine surgery, and its frequency is rising as the population ages. The study aim was to examine the influence of PD specifically on lumbar decompression surgery. METHODS: A retrospective review was performed of all patients with PD who underwent elective lumbar decompression surgery at two university hospital departments between December 2003 and July 2016. For each patient, two controls without PD were randomly selected among those who were matched for sex and age and had a similar year of surgery (±3) and comorbidity profile...

OBJECTIVE: Percutaneous endoscopic contralateral interlaminar lumbar foraminotomy (PECILF) for lumbar degenerative spinal stenosis is an established procedure. Better preservation of contralateral facet joint compared to that of the approach side has been demonstrated with uniportal bilateral decompression. The aim of this retrospective case series was to analyze the early clinical and radiological outcomes of standalone contralateral foraminotomy and lateral recess decompression using PECILF...

BACKGROUND: There are no studies about the biomechanical analysis of lumbar decompression surgery in relation to degenerative changes of the lumbar spine. Therefore, the purpose of this study was to compare, by using finite element (FE) analysis, the biomechanical changes of the lumbar spine in terms of annulus stress and nucleus pressure after two different kinds of lumbar decompression surgery in relation to disc degenerative changes. METHODS: The validated intact and degenerated FE models (L2-5) were used in this study...

BACKGROUND: Anterior clinoidal meningiomas (ACM) are traditionally approached through transcranial routes. Due to their tendency to extend laterally and their proximity to vital neurovascular structures, the endoscopic transnasal suprasellar approach is still questionable. We present and describe an ACM case that underwent an endoscopic transnasal suprasellar approach, and provide a review of the literature and operative technique. CASE DESCRIPTION: A 56 year-old lady who presented with chronic left-sided decreased vision...

A 52-year-old Japanese male professional diver was referred to our hospital for decompression illness (DCI). After 1 h of diving operation at 20 m below sea level, he complained of dyspnea, chest pain, and abdominal pain. He dove again, intending to ease the symptoms, but the symptoms were never relieved. He dove for a total of 4 h. No neurological abnormalities were observed. Computed tomography images revealed portal venous gas and mesenteric venous gas, in addition to bubbles in the femoral veins, pelvis, lumbar canal, intracranial sinuses, and joints...

BACKGROUND CONTEXT: The importance of surgeon volume as a quality measure has been defined for a number of surgical specialties. Meaningful procedural volume benchmarks have not been established, however, particularly with respect to lumbar spine surgery. PURPOSE: To establish surgeon volume benchmarks for the performance of four common lumbar spine surgical procedures (discectomy, decompression, lumbar interbody fusion, lumbar posterolateral fusion). STUDY DESIGN: Retrospective review of data in the Florida Statewide Inpatient Dataset (2011-2014)...

Remote cerebellar haemorrhage is a rare but serious complication after spinal surgery. Although the mechanism is not well known, it always occurs after loss of cerebrospinal fluid due to dural tear, not always identified, which produces remote venous bleeding. Prognosis depends largely on the severity of this bleeding. We report a case of 67-year-old female who suffered a cerebellar and subarachnoid haemorrhage and subdural haematoma after elective lumbar fusion surgery and eventually required decompressive craniectomy...

STUDY DESIGN: Retrospective study. PURPOSE: We report the surgical outcomes of small degenerative lumbar scoliosis (DLS) patients treated by a short-segment fusion and followed for a minimum of 5 years. OVERVIEW OF LITERATURE: Several surgical options are available for the treatment of DLS, such as decompression only, decompression plus a short-segment fusion, or decompression with a long segment fusion. Few studies have evaluated the results of a short-segment fusion in patients with DLS over time...

BACKGROUND: Tandem spinal stenosis refers to spinal canal diameter narrowing in at least 2 distinct regions of the spine, most commonly the lumbar and cervical regions. This entity can be an asymptomatic radiographic finding, or it can present with severe myelopathy and lower-extremity symptoms. Tandem spinal stenosis may impact surgeon decision-making when planning either cervical or lumbar spine surgery, and there is currently no consensus in the literature regarding the treatment algorithm for operative intervention...

OBJECTIVE Microsurgical decompression (MD) in patients with lumbar spinal stenosis (LSS) shows good clinical results. Nevertheless, 30%-40% of patients do not have a significant benefit after surgery-probably due to different anatomical preconditions. The sagittal profile types (SPTs 1-4) defined by Roussouly based on different spinopelvic parameters have been shown to influence spinal degeneration and surgical results. The aim of this study was to investigate the influence of the SPT on the clinical outcome in patients with LSS who were treated with MD...

PURPOSE: Lumbar central spinal stenosis (LSS) is one of the most common reasons for spine surgery in the elderly patient. Magnetic resonance imaging (MRI) represents the gold standard for the assessment of LSS and can be used to obtain quantitative measures of the dural sac cross-sectional area (DCSA) or qualitative measures (morphological grades A-D) of the rootlet/cerebrospinal fluid ratio. This study investigated the intercorrelation between these two MRI evaluation methods and explored their respective relationships with the patient baseline clinical status and outcome 12 months after surgery...

We present the case of a patient undergoing lumbar spine decompression for stenosis with a history of Mounier-Kuhn syndrome. The patient presented with axial lumbar spine pain over 6 months with progressive radicular pain to the left L3 dermatome. MRI confirmed spinal stenosis at L3/4 level with associated dural ectasia. The patient had an uneventful spinal decompression with resolution of radicular symptoms and axial spine pain. Dural ectasia poses a significant risk when operating on the lumbosacral spine...
