Intramedullary Spinal Cord Metastases and Radiation Therapy: A Case Report

Intramedullary spinal cord metastases (ISCM) are a clinically rare, although devastating, complication of disseminated cancer. These lesions have been reported to originate from many types of solid tumors, although primary lung carcinoma, particularly small cell, is the most common etiology. These metastases, which can occur anywhere along the spinal cord, often represent the end-stage of the disease process with limited survival outcomes. Patients with ISCM may develop a variety of neurological deficits with treatment goals aimed at palliation. Different modalities of treatment have been found to preserve or restore ambulation and neurological function. The options for therapeutic intervention include surgical, chemotherapeutic, and radiation therapy. We describe a case of ISCM in a patient with disseminated small cell lung cancer with magnetic resonance imaging that illustrates a complete tumor response to radiation therap

Whiplash: diagnosis, treatment, and associated injuries

Study design Focused review of the current literature. Objective To identify and synthesize the most current data pertaining to the diagnosis and treatment of whiplash and whiplash-associated disorders (WAD), and to report on whiplash-related injuries. Methods A search of OVID Medline (1996–January 2007) and the Cochrane database of systematic reviews was performed using the keywords whiplash and WAD. Articles under subheadings for pathology, diagnosis, treatment, and epidemiology were chosen for review after identification by the authors. Results A total of 485 articles in the English language literature were identified. Thirty-six articles pertained to the diagnosis, treatment, epidemiology of whiplash, and WAD, and were eligible for focused review. From these, 21 primary and 15 secondary sources were identified for full review. In addition, five articles were found that focused on whiplash associated cervical injuries. These five articles were also primary sources. Conclusions Whiplash is a common injury associated most often with motor vehicle accidents. It may present with a variety of clinical manifestations, collectively termed WAD. Whiplash is an important cause of chronic disability. Many controversies exist regarding the diagnosis and treatment of whiplash injuries. The multifactorial etiology, believed to underly whiplash injuries, make management highly variable between patients. Radiographic evidence of injury often cannot be identified in the acute phase. Recent studies suggest early mobilization may lead to improved outcomes. Ligamentous and bony injuries may go undetected at initial presentation leading to delayed diagnosis and inappropriate therapies

Return to Play after Cervical Spine Injuries: A Consensus of Opinion

Study Design: Survey. Objective: Sports-related spinal cord injury (SCI) represents a growing proportion of total SCIs but lacks evidence or guidelines to guide clinical decision-making on return to play (RTP). Our objective is to offer the treating physician a consensus analysis of expert opinion regarding RTP that can be incorporated with the unique factors of a case for clinical decision-making. Methods: Ten common clinical scenarios involving neurapraxia and stenosis, atlantoaxial injury, subaxial injury, and general cervical spine injury were presented to 25 spine surgeons from level 1 trauma centers for whom spine trauma is a significant component of their practice. We evaluated responses to questions about patient RTP, level of contact, imaging required for a clinical decision, and time to return for each scenario. The chi-square test was used for statistical analysis, with p \u3c 0.05 considered significant. Results: Evaluation of the surgeons’ responses to these cases showed significant consensus regarding return to high-contact sports in cases of cervical cord neurapraxia without symptoms or stenosis, surgically repaired herniated disks, and nonoperatively healed C1 ring or C2 hangman’s fractures. Greater variability was found in recommendations for patients showing persistent clinical symptomatology. Conclusion: This survey suggests a consensus among surgeons for allowing patients with relatively normal imaging and resolution of symptoms to return to high-contact activities; however, patients with cervical stenosis or clinical symptoms continue to be a challenge for management. This survey may serve as a basis for future clinical trials and consensus guidelines

Presentation and Outcomes After Medical and Surgical Treatment Versus Medical Treatment Alone of Spontaneous Infectious Spondylodiscitis: A Systematic Literature Review and Meta-Analysis.

Study Design: Systematic literature review. Objectives: The aims of this study were to (1) describe the clinical features, disabilities, and incidence of neurologic deficits of pyogenic spondylodiscitis prior to treatment and (2) compare the functional outcomes between patients who underwent medical treatment alone or in combination with surgery for pyogenic spondylodiscitis. Methods: A systematic literature review was performed using PubMed according to PRISMA guidelines. No year restriction was put in place. Statistical analysis of pooled data, when documented in the original report (ie, number of patients with desired variable and number of patients evaluated), was conducted to determine the most common presenting symptoms, incidence of pre- and postoperative neurologic deficits, associated comorbidities, infectious pathogens, approach for surgery when performed, and duration of hospitalization. Outcomes data, including return to work status, resolution of back pain, and functional recovery were also pooled among all studies and surgery-specific studies alone. Meta-analysis of studies with subgroup analysis of pain-free outcome in surgical and medical patients was performed. Results: Fifty of 1286 studies were included, comprising 4173 patients undergoing either medical treatment alone or in combination with surgery. Back pain was the most common presenting symptom, reported in 91% of patients. Neurologic deficit was noted in 31% of patients. Conclusion: Medical management remains first-line treatment of infectious pyogenic spondylodiscitis. Surgery may be indicated for progressive pain, persistent infection on imaging, deformity or neurologic deficits. If surgery is required, reported literature shows potential for significant pain reduction, improved neurologic function and a high number of patients returning to a normal functional/work status

Efficacy, Safety, and Timing of Anticoagulant Thromboprophylaxis for the Prevention of Venous Thromboembolism in Patients With Acute Spinal Cord Injury: A Systematic Review

Study Design: Systematic review. Objectives: The objective of this study was to answer 5 key questions: What is the comparative effectiveness and safety of (1a) anticoagulant thromboprophylaxis compared to no prophylaxis, placebo, or another anticoagulant strategy for preventing deep vein thrombosis (DVT) and pulmonary embolism (PE) after acute spinal cord injury (SCI)? (1b) Mechanical prophylaxis strategies alone or in combination with other strategies for preventing DVT and PE after acute SCI? (1c) Prophylactic inferior vena cava filter insertion alone or in combination with other strategies for preventing DVT and PE after acute SCI? (2) What is the optimal timing to initiate and/or discontinue anticoagulant, mechanical, and/or prophylactic inferior vena cava filter following acute SCI? (3) What is the cost-effectiveness of these treatment options? Methods: A systematic literature search was conducted to identify studies published through February 28, 2015. We sought randomized controlled trials evaluating efficacy and safety of antithrombotic strategies. Strength of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Results: Nine studies satisfied inclusion criteria. We found a trend toward lower risk of DVT in patients treated with enoxaparin. There were no significant differences in rates of DVT, PE, bleeding, and mortality between patients treated with different types of low-molecular-weight heparin or between low-molecular-weight heparin and unfractionated heparin. Combined anticoagulant and mechanical prophylaxis initiated within 72 hours of SCI resulted in lower risk of DVT than treatment commenced after 72 hours of injury. Conclusion: Prophylactic treatments can be used to lower the risk of venous thromboembolic events in patients with acute SCI, without significant increase in risk of bleeding and mortality and should be initiated within 72 hours. © 2017, © The Author(s) 2017

Incidence of fracture in adjacent levels in patients treated with balloon kyphoplasty: a review of the literature

The available evidence suggests that the treatment of painful vertebral compression fractures (VCFs) secondary to osteoporosis or multiple myeloma, by cement augmentation with balloon kyphoplasty (BK), is both safe and effective. However, there is uncertainty in the literature concerning the potential of the procedure to influence the risk for adjacent segment fracture. The aim of this article is to review the available peer-reviewed literature, regarding adjacent vertebral body fractures after kyphoplasty augmentation

Cervical spondylotic myelopathy in the young adult: A review of the literature and clinical diagnostic criteria in an uncommon demographic

Background: Cervical spondylotic myelopathy (CSM) is typically encountered in the elderly population. Significant inconsistencies currently exist regarding the definition of the disorder, the true incidence of CSM in younger populations, and the established diagnostic criteria. Objective: To highlight the lack of standardization in the definition and diagnosis of CSM. Methods: A PubMed literature search was conducted spanning the years 2001 to 2011. The search was limited by the following terms: 1) English language, 2) Adults (19-44 years old), and 3) “cervical spondylotic myelopathy.” Each article was reviewed to determine if the presence of the definition of CSM existed in the article. The clinical characteristics used to make the diagnosis of CSM were recorded for each article. Cochran’s Q statistic was used to determine whether some clinical characteristics were more frequently used than others. Results: 93 papers were reviewed in detail and 16 case reports, reviews, and articles concerning less than three patients were excluded, resulting in 77 articles in the final analysis. The most common clinical definitions were gait disturbance (22/77 articles (28.6%)), upper limb paresthesias or sensory disturbance (21/77 (27.3%)), and clumsy hands (15/77 (19.5%)). Hyperreflexia, spasticity, and pathologically increased reflexes were identified as diagnostic criteria in a minority of patients. Conclusion: The literature employs a wide range of neurologic signs and symptoms to make the diagnosis of CSM, with a majority of studies failing to rely on strict diagnostic criteria. The clinician should not discount CSM as an explanation for the aforementioned findings, as it is well-reported in the literature among the ages 18-44

Hemorrhage into an Occult Spinal Ependymoma after Epidural Anesthesia

Summary of Background Data: Five cases of hemorrhage into a spinal neoplasm after spinal or epidural anesthesia are reported in the literature. Presentation ranges from severe low back pain to acute cauda equina syndrome. Methods: A case study of a patient who hemorrhaged into an intradural, extramedullary spinal cord mass was performed. A detailed literature review is also provided. Results: A 27 year old female underwent epidural anesthesia for Cesarean section delivery. She presented with a 3 week history of increasing low back pain with bilateral radiculopathy. Imaging studies revealed a large hemorrhagic intradural mass compressing the lower conus medullaris and cauda equina, which operatively was confirmed to be a myxopapillary ependymoma. Conclusions: We report a case of hemorrhage into a previously unrecognized ependymoma after epidural anesthesia. Underlying tumors may rarely complicate regional anesthesia in the lumbar spine
