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: 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...

Ryanodine receptors (RyRs) are highly conductive intracellular Ca(2+) release channels and are widely expressed in many tissues, including the central nervous system. RyRs have been implicated in intracellular Ca(2+) overload which can drive secondary damage following traumatic injury to the spinal cord (SCI), but the spatiotemporal expression of the three isoforms of RyRs (RyR1-3) after SCI remains unknown. Here, we analyzed the gene and protein expression of RyR isoforms in the murine lumbar dorsal root ganglion (DRG) and the spinal cord lesion site at 1, 2 and 7 d after a mild contusion SCI...

STUDY DESIGN: An experimental biomechanical study. PURPOSE: This study aims to investigate the behavior of a lamina injury in lumbar burst fractures during reduction maneuvers. OVERVIEW OF LITERATURE: Lumbar burst fractures are frequently accompanied by a lamina fracture. Many researchers concluded that any reduction maneuver will close the fractured lamina edges and possibly crush the entrapped neural elements. This conclusion did not rely on solid biomechanical trials and was based primarily on clinical experience...

BACKGROUND: Spinal surgery is classified as a moderate risk for DVT. The occurrence of DVT after various spinal surgical procedures was reviewed retrospectively, and the perioperative risk factors in the high-risk group were identified. In addition, the administration of the factor Xa inhibitor to DVT subjects with unstable thrombosis was evaluated to reveal its effectiveness in the prevention of PTE and postoperative complications. METHODS: This study included 588 subjects who underwent lumbar spine surgery...

BACKGROUND: Patients with marked osteoporosis and/or obesity/morbid obesity and severe multilevel lumbar stenosis and other pathology often undergo multilevel laminectomies with non instrumented posterolateral fusions (PLF). The other pathology may include combinations of degenerative spondylolisthesis/lysis, foraminal/far lateral discs, and/or synovial cysts requiring more extensive facet resections. Presently, spine surgeons often use bone graft expanders to supplement the lamina autograft harvested in the course of laminectomy/decompressions for the PLF mass...

Electrospun fibrous membranes provide suitable physical anti-adhesion barriers for reducing tissue anti-adhesion following surgery. However, often during the biodegradation process, these barriers trigger inflammation and cause a foreign body reaction with subsequent decrease in anti-adhesion efficacy. Here, a facile strategy comprising the incorporation of ibuprofen (IBU) into implantable membranes and its sustained release was proposed in order to improve anti-adhesion effects and neurological outcomes, namely to prevent failed back surgery syndrome (FBSS)...

STUDY DESIGN: Multicenter retrospective study. BACKGROUND: Postoperative surgical site infection is one of the most serious complications following spine surgery. Previous studies do not appear to have investigated pyogenic discitis following lumbar laminectomy without discectomy. This study aimed to identify risk factors for postoperative pyogenic discitis following lumbar decompression surgery. METHODS: We examined data from 2721 patients undergoing lumbar laminectomy without discectomy in five hospitals from April 2007 to March 2012...

Cauda equina syndrome (CES) resulting from acute lumbar disc herniation due to spinal massage is extremely rare. We present a case of CES caused by the acute worsening of a lumbar disc herniation after a vigorous back massage that included spinal manipulation. After vigorous back massage with spinal manipulation performed by a massage therapist, a 38-yr-old male patient experienced CES with severe numbness in both lower limbs, inability to walk due to weakness of bilateral lower limbs, and incontinence of urine and feces...

RATIONALE: Gout in the spine is very rare. The clinical symptoms of the spinal gout are various and lack of specificity. The authors report a case of spinal gout causing lumbar stenosis. We never find such wide-invasive spinal gouty lesion in the published studies. PATIENT CONCERNS: A 68-year-old male had low back pain radiating to bilateral lower limbs, accompanying with intermittent claudication that lasted for 3 months and aggravated 5 days ago. DIAGNOSES: Spinal gout, lumbar stenosis...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is a disorder that can cause neurologic deterioration. Studies on paraspinal muscular atrophy (PMA) in the lumbar spine have shown these changes are caused by several perioperative factors. It is possible that PMA in the cervical spine could behave similarly. In this retrospective study, we compared the degree of PMA after laminoplasty versus laminectomy and fusion (LF) using a standard posterior approach to the cervical spine. METHODS: 18 laminoplasty and 43 LF patients were included in this study...

BACKGROUND: The lumbar spine includes 5 lumbar vertebral bodies, L1, L2, L3, L4, and L5. At each level, there is a disc space defined by the two bones (vertebral bodies) in the back; for example, there is a disc space at the L5-S1 level etc. The normal front to back (anterior to posterior or AP diameter) measurement of the spinal canal is typically 18-20 mm, but some patients have narrowing called spinal stenosis. METHODS: Lumbar stenosis is defined by two major types...

INTRODUCTION: Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. METHODS: Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina...

OBJECTIVES: Xenograft bone plate-screws (XBPSs) can be alternative tools in lumbar transpedicular stabilization (TS). The aim of this study was to show biomechanical and histopathological contribution of the XBPSs system in lumbar TS. MATERIALS AND METHODS: Fifteen (n = 15) hybrid dog and ten (n = 10) L2-4 cadaveric specimens were included in the study. The dogs were separated according to surgical techniques: L3 laminectomy and bilateral facetectomy (LBF) in Group I (experimental group [EG I] (n = 5), L3 LBF plus TS with metal plate-screws (MPSs) in Group II (EG II) (n = 5), and L3 LBF plus TS with XBPSs in Group III (EG III) (n = 5)...

BACKGROUND: At our centre, laminectomies have been traditionally performed as inpatient surgery. A gradual change in practice occurred between 2010 and 2013 to try to do these procedures as outpatient or overnight stay surgery. METHODS: We conducted a retrospective cohort study of consecutive patients having laminectomies over 2 18-month periods: before the change in practice and after full implementation of the outpatient/overnight stay protocol. We collected information on patient characteristics (age, sex, American Society of Anesthesiologists [ASA] classification, home address, number of laminectomy levels, estimated blood loss) and patient outcome (complications, hospital length of stay, 30-day readmissions)...

Surgical correction of fixed thoracolumbar deformity is usually achieved by estimating the preoperatively planned correction angles during surgery and is therefore prone to inaccuracy. This is particularly problematic in biplanar deformities. To overcome these difficulties, 3D model for planning, preparation, and simulation of an asymmetric pedicle subtraction osteotomy (aPSO) was printed and used to realign coronal and sagittal balance in case of rigid degenerative kyphoscoliosis. A 59-year-old woman presented with severe back pain and spinal claudication and was diagnosed with a rigid kyphoscoliosis with multilevel spinal stenosis...

Mobile Schwannoma is a very rare entity and is reported sparsely in literature, with most of them occurring in lumbar spine region. We present a case of seventy-year-old male patient who had pain in lower back radiating to ipsilateral thigh. A diagnosis of migratory tumour was made based on findings of plain and contrast MRI preoperatively. We did a two level laminectomy and tumour excision. In this report, we intend to discuss various likely causes of tumour migration and various diagnostic methods to tackle this surgical dilemma, we have also attempted to review the sparse literature available till date on migratory lumber schwannoma...
