WHS guidelines for the treatment of pressure ulcers-2023 update.

The major populations at risk for developing pressure ulcers are older adults who have multiple risk factors that increase their vulnerability, people who are critically ill and those with spinal cord injury/disease. The reported prevalence of pressure ulcers in the United States is 2.5 million.

The Surgical Management of Holospinal Epidural Abscess: A Case Report and Review on Catheter-Based Irrigation Techniques.

Holospinal epidural abscess (HEA) is an extremely rare spinal infection involving the entire spine and is infrequently reported in the literature. Cases with evidence of spinal cord compression and consequent neurological deficit are typically managed with prompt surgical drainage and broad-spectrum antibiotics. Surgical intervention is often challenging because this condition is inherently associated with poor prognosis and serious complications, including death.

Congenital Agenesis of the C6 Pedicle Leading to Misdiagnosis of a Traumatically Jumped Facet: A Case Report.

This case report discusses the rare issue of an atrophic cervical pedicle at the C6 level in a patient found unconscious with a jumped facet and an unknown mechanism of injury. A means to discern between traumatic jumped facets versus congenital anomalies is addressed, including missing pedicles, which is encountered at the C6 level in this case. A literature review revealed that the most common level where this occurs is at the C6 level.

Association Between Allogeneic Blood Transfusion and Postoperative Infection in Major Spine Surgery.

Study Design: Retrospective cohort study.

Objective: The objective of this study is to compare the incidence of infection in patients who do and do not receive blood transfusions in major deformity surgery (>8 levels).

Summary Of Background Data: Postoperative infections increase morbidity and mortality rates in spine surgery and generate additional costs for the health care system.

Subdural Thoracolumbar Spine Hematoma after Spinal Anesthesia: A Rare Occurrence and Literature Review of Spinal Hematomas after Spinal Anesthesia.

Spinal hematomas are a rare but serious complication of spinal epidural anesthesia and are typically seen in the epidural space; however, they have been documented in the subdural space. Spinal subdural hematomas likely exist within a traumatically induced space within the dural border cell layer, rather than an anatomical subdural space. Spinal subdural hematomas present a dangerous clinical situation as they have the potential to cause significant compression of neural elements and can be easily mistaken for spinal epidural hematomas.

Posterior arch C-1 screw technique: a cadaveric comparison study.

OBJECTIVE Posterior atlantoaxial stabilization and fusion using C-1 lateral mass screw fixation has become commonly used in the treatment of instability and for reconstructive indications since its introduction by Goel and Laheri in 1994 and modification by Harms in 2001. Placement of such lateral mass screws can be challenging because of the proximity to the spinal cord, vertebral artery, an extensive venous plexus, and the C-2 nerve root, which overlies the designated starting point on the posterior center of the lateral mass. An alternative posterior access point starting on the posterior arch of C-1 could provide a C-2 nerve root-sparing starting point for screw placement, with the potential benefit of greater directional control and simpler trajectory.

Anatomical complications of epidural anesthesia: A comprehensive review.

Epidural anesthesia is a versatile technique widely used in treating lumbar spinal pain syndromes. Complications during these procedures can arise either from needle placement or from administration of medication. Potential risks include infection, hematoma, intravascular or subdural injections of medication, direct nerve trauma, air embolism, entry into a disc space, urinary retention, radiation exposure, and hypersensitivity reactions.

Descriptive analysis of unplanned readmission and reoperation rates after intradural spinal tumor resection.

Introduction: Spinal cord tumors (SCT) are relatively uncommon and usually require surgical treatment. Readmission within 30days after discharge is an important indicator of health care quality. The aim of this study was to investigate the rates and causes of unplanned readmissions and reoperations after SCT surgery.

Advancement of Surgical Visualization Methods: Comparison Study Between Traditional Microscopic Surgery and a Novel Robotic Optoelectronic Visualization Tool for Spinal Surgery.

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.

Herpes Simplex Encephalitis of the Parietal Lobe: A Rare Presentation.

A 69-year-old female with a history of breast cancer and hypertension presented with a rare case of herpes simplex encephalitis (HSE) isolated to her left parietal lobe. The patient's first biopsy was negative for herpes simplex virus (HSV) I/II antigens, but less than two weeks later, the patient tested positive on repeat biopsy. This initial failure to detect the virus and the similarities between HSE and symptoms of intracranial hemorrhage (ICH) suggests repeat testing for HSV in the presence of ICH.

Lateral Thoracic Osteoplastic Rib-Sparing Technique Used for Lateral Spine Surgery: Technical Note.

Of patients who have undergone lateral approaches to the thoracic spine, surgical site postoperative pain appears to be greater among those who have undergone transection and removal of a rib segment than those who have not. Therefore, techniques that conserve anatomical position and minimize tissue disruption would theoretically result in less pain and a quicker recovery. Herein, we describe a rib-sparing osteoplastic technique used when rib segments need to be displaced in order to create an unobscured corridor to the operative target.

Venous air embolus during prone cervical spine fusion: case report.

Venous air embolism (VAE) is a known neurosurgical complication classically and most frequently occurring in patients undergoing posterior cranial fossa or cervical spine surgery in a sitting or semi-sitting position. The authors present a case of VAE that occurred during posterior cervical spine surgery in a patient in the prone position, a rare intraoperative complication. The patient was a 65-year-old man who was undergoing a C1-2 fusion for a nonunion of a Type II dens fracture and developed a VAE.

Unilateral Laminotomy with Bilateral Spinal Canal Decompression for Lumbar Stenosis: A Technical Note.

Lumbar stenosis has become one of the most common spinal pathologies and one that results in neurogenic claudication, back and leg pain, and disability. The standard procedure is still an open laminectomy, which involves wide muscle retraction and extensive removal of the posterior spinal structures. This can lead to instability and the need for additional spinal fusion.

Dural-Based Cavernoma of the Posterior Cranial Fossa Mimicking a Meningioma: A Case Report.

Cavernous angiomas usually occur in the parenchyma of both the supra and infratentorial compartments. At times, they can both clinically and radiologically mimic other dural-based lesions. We present a case of a patient with chronic occipital headaches, initially thought to have a meningioma, but proven to be a cavernoma with histological analysis.

Lumbar Epidural Hematoma Following Interlaminar Fluoroscopically Guided Epidural Steroid Injection.

Objective: Spinal epidural steroid injections are generally considered a safe, effective treatment for radicular pain in a variety of spinal conditions. Complications secondary to these injections, although rare, can result in devastating neurologic symptoms. Patients with preexisting moderate-to-severe spinal stenosis and recent use of chronic anticoagulation pose a challenging dilemma when making treatment decisions, as a history of both can increase the risk of complications.

Training Medical Novices in Spinal Microsurgery: Does the Modality Matter? A Pilot Study Comparing Traditional Microscopic Surgery and a Novel Robotic Optoelectronic Visualization Tool.

The operative microscope has been a staple instrument in the neurosurgical operating room over the last 50 years. With advances in optoelectronics, options such as robotically controlled high magnification have become available. Such robotically controlled optoelectronic systems may offer new opportunities in surgical technique and teaching.

Bullet Fragment of the Lumbar Spine: The Decision Is More Important Than the Incision.

Study Design Case report. Objective Treatment of gunshot wounds to the spine is a topic of continued discussion and controversy. The following case study provides a description of a patient with a gunshot wound to the lumbar spine with a retained bullet in the intrathecal space.

Technical Note - Lateral Approach to the Lumbar Spine for the Removal of Interbody Cages.

Revision surgery to address the migration or fracture of a lumbar interbody cage can be technically challenging. Scar tissue and fibrosis, among other anatomic barriers, can make removal of the cage a complicated procedure, potentially increasing postoperative pain as well as the probability of neurologic deficits. Use of the lateral surgical technique for removal of the cage can avoid these potential complications.

Nonalcoholic fatty liver disease: the hepatic metabolic syndrome.

Purpose: To examine a case of nonalcoholic fatty liver disease (NAFLD) and review the incidence, pathophysiology, appropriate diagnostic procedures and imaging, clinical considerations, and treatment options.

Data Sources: Findings from the history, physical examination, and diagnostic testing of a 39-year-old man with elevated liver enzymes presenting to the hepatology clinic; a search of evidence-based literature in the PubMed and CINAHL database with the terms "fatty liver,""nonalcoholic fatty liver disease," and "nonalcoholic steatohepatitis."

Conclusions: NAFLD is the deposition of fat in the liver that can progress to nonalcoholic steatohepatitis, resulting in fibrosis and cirrhosis.
