Simple Summary: Metastatic spinal cord compression (MSCC) is characterised by the compression of the spinal cord due to direct or metastatic spread to the vertebrae, potentially leading to neurological deficits. This condition constitutes an urgent situation in oncology, demanding swift diagnosis and immediate intervention due to the considerable risk of spinal cord damage and irreversible neurological repercussions. Spinal tumours resulting from the metastasis of lung cancer are particularly connected with an unfavourable prognosis, often displaying rapid advancement and limited survival. Treatment approaches encompass a combination of radiotherapy and potential surgery, which are tailored to each patient's situation. Within this retrospective study, our goal was to pinpoint prognostic elements that impact the survival rates of lung cancer patients experiencing MSCC. Identifying such prognostic factors associated with shorter or longer survival subsequent to MSCC could contribute to tailoring distinct, more or less intensive therapeutic strategies for these individuals. Purpose: Metastatic spinal cord compression (MSCC) is a severe complication of cancer that can lead to irreversible neurological impairment, necessitating prompt recognition and intervention. This retrospective, single-centre study aimed to determine the prognostic factors and survival rates among patients presenting with MSCC secondary to lung cancer. Methods and Materials: We identified 74 patients with epidural metastases-related spinal cord compression and a history of lung cancer through the electronic database of Medway Maritime Hospital in the United Kingdom (UK), spanning the period from April 2016 to September 2021. Among them, 39 were below 55 years old, while 35 were aged 55 years or older; 24 patients were diagnosed with small cell lung cancer (SCLC), and 50 patients had non-small cell lung cancer (NSCLC). Results: The median overall survival (OS) was 5.5 months, with 52 out of 74 patients dying within 6 months of diagnosis with MSCC. For the entire cohort, the statistically significant variables on multi-variate analysis were cancer type (NSCLC had improved OS), the number of involved vertebrae (one to two vertebrae involvement had improved OS), and the time taken to develop motor deficits (≤10 days to develop motor deficits had worsened OS). For the NSCLC cohort, the statistically significant variables on multivariate analysis were molecular alterations (patients with epidermal growth factor receptor (EGFR) mutation), pre-treatment ambulatory status, Eastern Cooperative Oncology Group (ECOG) performance status, and the time taken to develop motor deficits. Conclusions: Within the entire cohort, patients diagnosed with NSCLC and spinal metastases affecting one to two vertebrae exhibited enhanced OS. Within the NSCLC subgroup, those with EGFR mutations who were ambulatory and possessed an ECOG performance status of 1–2 demonstrated improved OS. In both the entire cohort and the NSCLC subgroup, the development of motor deficits within a period of ≤10 days was associated with poor OS. [ABSTRACT FROM AUTHOR]

To report efficacy and safety of percutaneous electrochemotherapy (ECT) in patients with radiotherapy-resistant metastatic epidural spinal cord compression (MESCC). This retrospective study analyzed all consecutive patients treated with bleomycin-based ECT between February-2020 and September-2022 in a single tertiary referral cancer center. Changes in pain were evaluated with the Numerical Rating Score (NRS), in neurological deficit with the Neurological Deficit Scale, and changes in epidural spinal cord compression were evaluated with the epidural spinal cord compression scale (ESCCS) using an MRI. Forty consecutive solid tumour patients with previously radiated MESCC and no effective systemic treatment options were eligible. With a median follow-up of 5.1 months [1–19.1], toxicities were temporary acute radicular pain (25%), prolonged radicular hypoesthesia (10%), and paraplegia (7.5%). At 1 month, pain was significantly improved over baseline (median NRS: 1.0 [0–8] versus 7.0 [1.0–10], P <.001) and neurological benefits were considered as marked (28%), moderate (28%), stable (38%), or worse (8%). Three-month follow-up (21 patients) confirmed improved over baseline (median NRS: 2.0 [0–8] versus 6.0 [1.0–10], P <.001) and neurological benefits were considered as marked (38%), moderate (19%), stable (33.5%), and worse (9.5%). One-month post-treatment MRI (35 patients) demonstrated complete response in 46% of patients by ESCCS, partial response in 31%, stable disease in 23%, and no patients with progressive disease. Three-month post-treatment MRI (21 patients) demonstrated complete response in 28.5%, partial response in 38%, stable disease in 24%, and progressive disease in 9.5%. This study provides the first evidence that ECT can rescue radiotherapy-resistant MESCC. • Radiotherapy-resistant metastatic spinal cord compression is an unmet medical need. • Electrochemotherapy (ECT) improves neurological in this advanced cancer setting. • ECT also results in significant pain decrease at 1-month and 3-months. • At MRI, 77% of patients had an objective response at 1 month and 66.5% at 3 months. • Complications were overall minor, with the exception of paraplegia in 7.5% of patients.

Simple Summary: Most Spanish specialists involved in the clinical management of spinal cord compression are familiar with the scoring systems for spine instability and spinal compression as well as with the NICE guideline recommendations. However, many do not apply them in routine practice. Scores on the scales used to evaluate spine instability in neoplastic diseases were interpreted correctly by 57.5–70.0% of the practitioners while scores of the spinal cord compression grading system were interpreted correctly by 30.0–37.5%. There is room for improvement in the management of SMD in routine practice. (1) Background: Whether clinical management of spinal metastatic disease (SMD) matches evidence-based recommendations is largely unknown. (2) Patients and Methods: A questionnaire was distributed through Spanish Medical Societies, exploring routine practice, interpretation of the SINS and ESCC scores and agreement with items in the Tokuhashi and SINS scales, and NICE guideline recommendations. Questionnaires were completed voluntarily and anonymously, without compensation. (3) Results: Eighty specialists participated in the study. A protocol for patients with SMD existed in 33.7% of the hospitals, a specific multidisciplinary board in 33.7%, 40% of radiological reports included the ESCC score, and a prognostic scoring method was used in 73.7%. While 77.5% of the participants were familiar with SINS, only 60% used it. The different SINS and ESCC scores were interpreted correctly by 57.5–70.0% and 30.0–37.5% of the participants, respectively. Over 70% agreed with the items included in the SINS and Tokuhashi scores and with the recommendations from the NICE guideline. Differences were found across private/public sectors, hospital complexity, number of years of experience, number of patients with SMD seen annually and especially across specialties. (4) Conclusions: Most specialists know and agree with features defining the gold standard treatment for patients with SCC, but many do not apply them. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lumbar intervertebral disc height loss has been associated with spinal height change (SHC) and low back pain (LBP), including stenosis. Non-invasive methods to improve disc height loss require forms of lying down, which are unconducive to computer work. OBJECTIVE: Intermittent vertical traction (VT) integrated with seated computer work may provide ergonomic alternatives for increasing SHC to promote LBP relief. The primary aim was to develop and introduce a safe VT prototype and dosage to induce and measure SHC. Prototype comfort and LBP ratings were exploratory secondary aims. METHODS: Forty-one participants were stadiometry-measured for pre- and post-intervention SHC from seated VT at 35% body weight removed, supine lying (SL), and sitting at a computer (SIT) without VT. Pain ratings were recorded for those self-reporting LBP. VT prototype evaluations were compiled from a 3-question, 7-point Likert-style survey. RESULTS: SHC increased by 3.9 ± 3.4 mm in VT, 1.7 ± 3.4 mm in SIT, and 4.3 ± 3.1 mm in SL (P < 0.000). Post hoc findings were significant between VT and SIT (P < 0.000), and SL and SIT (P < 0.000). VT and SL LBP ratings both decreased, but not SIT. CONCLUSION: Intermittent seated VT is a promising alternative for postural relief during seated computer work, producing SHC similar to lying down without compromising workflow.

Objective: Patients presenting with neurological deficit secondary to metastatic epidural spinal cord compression (MESCC) are often treated with surgery in combination with high-dose corticosteroids. Despite steroids being commonly used, the evidence regarding the effect of corticosteroids on patient outcomes is limited. The objective of this study was to describe the effect of corticosteroid use on preoperative neurological function in patients with MESCC. Methods: Patients who underwent surgery between August 2013 and February 2017 for the treatment of spinal metastases and received steroids to prevent neurologic deficits were included. Data regarding demographics, diagnosis, treatment, neurological function, adverse events, health-related quality of life, and survival were extracted from an international multicenter prospective cohort. Results: A total of 30 patients treated surgically and receiving steroids at baseline were identified. Patients had a mean age of 58.2 years (standard deviation, 11.2 years) at time of surgery. Preoperatively, 50% of the patients experienced deterioration of neurological function, while in 30% neurological function was stable and 20% improved in neurological function. Lengthier steroid use did not correlate with improved or stabilized neurological function. Postoperative adverse events were observed in 18 patients (60%). Patients that stabilized or improved neurologically after steroid use showed a trend towards improved survival at 3- and 24-month postsurgery. Conclusion: This study described the effect of steroids on preoperative neurological function in patients with MESCC. Stabilization or improvement of preoperative neurological function occurred in 50% of the patients. [ABSTRACT FROM AUTHOR]

PURPOSE To determine if a quality improvement (QI) initiative could enhance multidisciplinary management of acute malignant extradural spinal cord compression (ESCC) at our institution. METHODS The medical records of all 40 patients who received palliative radiotherapy for malignant ESCC from 2015 to 2017 were reviewed to determine the time course of key National Comprehensive Cancer Network guideline–supported workup and management steps. On the basis of the findings, a multidisciplinary group of physician stakeholders developed a clinical pathway to facilitate expedited care. The efficacy of this clinical pathway and the educational content provided to all relevant departments were then evaluated by comparing outcomes with data from a similarly reviewed follow-up cohort of 25 patients from 2018 to 2019. RESULTS Patients treated for malignant ESCC after our QI intervention were more likely to undergo magnetic resonance imaging (MRI) of the entire spine (64% v 44%; P = .013) and have a radiation oncology (RO) consultation before surgery (100% v 27%; P = .002). Median time from MRI to RO consultation decreased from 3 to 1 days (P = .03). On subgroup analysis, initial trends toward delays in RO consultation for patients planning for surgery (median, 3 days) or for lack of prior cancer diagnosis (median, 4 days) were reduced to delays of 0 and 1 day, respectively, after the QI intervention. No significant differences were observed in time to surgical consultation or surgery itself. CONCLUSION This QI study was able to stimulate better use of diagnostic imaging and earlier involvement of RO in multidisciplinary decision making, suggesting an effective approach to improving multidisciplinary care in other scenarios as well.

Degenerative cervical myelopathy (DCM) is the leading cause of spinal cord dysfunction in adults worldwide. DCM encompasses various acquired (age-related) and congenital pathologies related to degeneration of the cervical spinal column, including hypertrophy and/or calcification of the ligaments, intervertebral discs and osseous tissues. These pathologies narrow the spinal canal, leading to chronic spinal cord compression and disability. Owing to the ageing population, rates of DCM are increasing. Expeditious diagnosis and treatment of DCM are needed to avoid permanent disability. Over the past 10 years, advances in basic science and in translational and clinical research have improved our understanding of the pathophysiology of DCM and helped delineate evidence-based practices for diagnosis and treatment. Surgical decompression is recommended for moderate and severe DCM; the best strategy for mild myelopathy remains unclear. Next-generation quantitative microstructural MRI and neurophysiological recordings promise to enable quantification of spinal cord tissue damage and help predict clinical outcomes. Here, we provide a comprehensive, evidence-based review of DCM, including its definition, epidemiology, pathophysiology, clinical presentation, diagnosis and differential diagnosis, and non-operative and operative management. With this Review, we aim to equip physicians across broad disciplines with the knowledge necessary to make a timely diagnosis of DCM, recognize the clinical features that influence management and identify when urgent surgical intervention is warranted.

Cancer emergencies comprise a group of medical conditions presented by patients with an underlying malignant neoplasm and demands high clinical suspicion. Proper management depends on a fast and precise diagnosis, and the outcomes may impact patient survival and quality of life. In countries where early detection programs are not adequately implemented, a significant proportion of patients present with emergency symptoms as their first sign of disease. This chapter will give an overview of diagnosis and treatment of hypercalcemia, tumor lysis syndrome, cardiac tamponade, metastatic spinal cord compression and superior vena cava syndrome.

Background: metastatic spinal cord compression (MSCC) is an oncology emergency. Prevalence is increasing. Treatment and care are complex and those diagnosed may be faced with life-changing challenges. Aims: to review the impact and management of MSCC in patients with cancer, in order to analyse nursing considerations for supporting patients. Methods: a literature review and thematic analysis of five primary research papers, published between 2009 and 2014. Findings: two themes of prognosis/survival time and independence versus dependence were discovered. Conclusions: the onset of MSCC may result in paralysis and associated loss of independence, impacting on a patient's quality of life. Understanding individuals' prognosis and treatment/care preferences is fundamental for the sensitive, individualised support of patients with MSCC. The findings reinforce the nurses' role in health education, in order to raise awareness of MSCC and promote early diagnosis so that patients maintain function and independence as long as possible. The findings support the need for nurses to be equipped with appropriate communication skills to initiate and engage in sensitive, difficult and proactive conversations with patients and their families, supporting the delivery of humanised care.

Study Design: A multicenter retrospective study of patients who underwent unilateral and bilateral balloon kyphoplasty.Objective: The aim of this study was to compare the radiographic and clinical results of unilateral and bilateral balloon kyphoplasty to treat osteoporotic vertebral compression fractures.Summary Of Background Data: Percutaneous kyphoplasty has long been used as a successful method in the treatment of osteoporotic vertebral compression fractures. Although the bilateral approach is considered to be the mainstay application of percutaneous kyphoplasty, the unilateral approach has also been shown to be sufficient and even more effective in some cases.Methods: A total of 87 patients who underwent percutaneous kyphoplasty due to osteoporotic vertebral compression fractures between 2009 and 2016 were retrospectively evaluated and divided into two groups as patients who underwent unilateral or bilateral percutaneous kyphoplasty. Unilateral percutaneous kyphoplasty was performed in 36 and bilateral percutaneous kyphoplasty in 51 patients. The groups were compared in terms of clinical outcomes, radiological findings, and complications. Clinical outcomes were evaluated using Visual Analogue Scale and Oswestry Disability Index and the radiological findings were evaluated by comparing the preoperative and postoperative day 1 and year 1 values of anterior, middle, and posterior vertebral heights and kyphosis angle.Results: Clinical improvement occurred in both groups but no significant difference was observed. In radiological workup, no significant difference was found between the groups in terms of improvements in vertebral heights and kyphosis angle. Operative time and the amount of cement used for the surgery were significantly lower in the patients that underwent unilateral kyphoplasty.Conclusion: Unilateral percutaneous kyphoplasty is as effective as bilateral percutaneous kyphoplasty both radiologically and clinically. Operative time and the amount of cement used for the surgery are significantly lower in unilateral kyphoplasty, which may play a role in decreasing complication rates.Level Of Evidence: 3.

BETA-Thalassemia , *EXTRAMEDULLARY hematopoiesis ,TREATMENT of spinal cord compression - Abstract
Extramedullary hematopoiesis (EMH) in individuals with thalassemia is often the result of undertreated severe anemia. Radiation or surgery is often the chosen approach to handle spinal cord compression due to these paraspinal EMH elements. Our patient is a 28-year-old male with E-beta-thalassemia who presented with both upper thoracic and lower extremity symptoms of spinal cord compression and was successfully managed with the combination of transfusion and hydroxyurea. Given the variation in symptoms as a result of the sporadic location as well as the extent of these EMH elements along the spinal canal, the hematological communities will continue to benefit from case reports that offer treatment therapy.

Background Context: Surgical decompression and stabilization followed by radiosurgery represents an effective method for local tumor control and neurologic preservation for patients with metastatic epidural spinal cord compression (MESCC). We have previously demonstrated improvement in health-related quality of life (HrQOL) after this combined modality treatment ("hybrid therapy").Purpose: The current analysis focuses on delineation of patient-specific prognostic factors predictive of HrQOL change after combined surgery-stereotactic radiosurgery (SRS) treatment of MESCC.Study Design: This is a prospective, single-center, cohort study.Patient Sample: One hundred and eleven patients with MESCC who underwent separation surgery followed by SRS were included.Outcome Measures: Prognostic factors associated with improved patient-reported outcome (PRO) measures.Methods: Patient-reported outcome tools, that is, Brief Pain Inventory (BPI) and MD Anderson Symptom Inventory-Spine Tumor (MDASI-SP), both validated in the cancer population, were prospectively collected. Numeric prognostic factors were correlated with PRO measures using the Spearman rank correlation coefficient. Categorical prognostic factors were correlated with PRO measures using the Wilcoxon two-sample test (for two categories) or the Kruskal-Wallis test (for three or more categories). All statistical tests were two-sided with a level of significance <.05 for correlation of prognostic factors with PRO constructs and a level of significance <.0014 for correlation of prognostic factors with PRO items. Statistical analyses were done in SAS (version 9.4, Cary, NC, USA).Results: One hundred and eleven patients were included in this analysis. Patients with lower preoperative Medical Research Council (MRC) motor scores experienced a greater decrease in symptom interference (BPI interference construct (p=.03) and individual functional measures including general activity (p=.001), walking (p=.001), and normal work (p=.006)). Lumbar location was associated with better outcomes than cervical or thoracic as noted on the BPI pain experience construct (p=.03) and MDASI-SP interference (p=.01) and core symptom (p=.002) constructs. Patients with American Spinal Injury Association (ASIA) scores of C or D benefit more than those with ASIA E on BPI interference construct (p=.04). Patients with higher Eastern Cooperative Oncology Group (ECOG) scores at presentation benefit more than those with low ECOG scores on MDASI-SP interference construct (p=.03). Women benefit more than men on BPI interference (p=.03) and pain experience (p=.04) constructs. Patients with prior spinal surgery at the current level of interest benefit less than those who are naïve surgical patients in MDASI-SP interference construct (p=.04).Conclusions: Delineation of patient characteristics associated with HrQOL improvement provides crucial information for patient selection, patient education, and setting treatment expectations. For patients with MESCC treated with hybrid therapy using surgery and radiosurgery, the presence of neurologic deficits and diminished performance status, lumbar tumor level, and female gender were associated with greater PRO improvement.

Background and Context: Metastatic epidural spinal cord compression (MESCC) is a disabling consequence of disease progression. Surgery can restore or preserve physical function, improving access to treatments that increase duration of survival; however, advanced patient age may deter oncologists and surgeons from considering surgical management.Purpose: Evaluate the duration of ambulation and survival in elderly patients following surgical decompression of MESCC.Study Design/setting: Retrospective file review of a prospective database, under institutional review board (IRB) waiver of informed consent, of consecutive patients treated in an academic tertiary care medical center from August 2008 to March 2015.Patient Sample: Patients ≥65 years presenting neurological and/or radiological signs of cord compression because of metastatic disease, who underwent surgical decompression.Outcome Measures: Duration of ambulation and survival.Methods: Patients underwent urgent multidisciplinary evaluation and surgery. Ambulation and survival were compared with age, pre-, and postoperative neurological (American Spinal Injury Association [ASIA] Impairment Scale [AIS]) and performance status (Karnofsky Performance Status [KPS]), and Tokuhashi Score using Kruskal-Wallis and Wilcoxon signed rank tests, Pearson correlation coefficient, Cox regression model, log-rank analysis, and Kaplan-Meier analysis.Results: Forty patients were included (21 male, 54%; mean age 74 years, range 65-87). Surgery was performed a mean 3.8 days after onset of motor symptoms. Mean duration of ambulation and survival were 474 (range 0-1662) and 525 days (range 11-1662), respectively; 53% of patients (21 of 40) survived and 43% (17 of 40) retained ambulation for ≥1 year. There was no significant relationship between survival and ambulation for patients aged 65-69, 70-79, or 80-89 years, although Kaplan-Meier analysis suggested stratification. There was a significant relationship between duration of ambulation and pre- and postoperative AIS (p=.0342, p=.0358, respectively) and postoperative KPS (p=.0221). Tokuhashi score was not significantly related to duration of survival or ambulation, and greatly underestimated life expectancy in 22 of 37 (59%) patients with scores 0-11.Conclusions: Decompressive surgery led to marked improvement in neurological function and performance status. More than 50% of patients survived for >1 year, some for 3 years or more after surgery. [ABSTRACT FROM AUTHOR]- Published

Study Design: A retrospective multicenter study.Objective: To identify the incidence of anterior arch fracture (AAF) of the atlas following C1 (first cervical vertebra) laminectomy without fusion, and its risk factors.Summary Of Background Data: C1 laminectomy without fusion is a widely accepted surgical procedure performed to decompress the spinal cord that is compromised at the C1/C2 level, but without instability. Several case series have reported spontaneous AAF following this procedure. However, the incidence of post-laminectomy AAF and its risk factors have not been studied.Methods: This retrospective study included patients who underwent C1 laminectomy without fusion in any of the four participating institutions between April 2002 and March 2016. The incidence of AAF following C1 laminectomy was determined, and the included patients were grouped into those who developed AAF (AAF group) and those who did not (non-AAF group). Patient demographics and radiographic parameters including subaxial cervical balance on x-ray (C2-7 sagittal vertical axis, C2-7 lordosis, C2-7 coronal cobb angle, and T1-slope), and morphology of the atlas on computed tomography (CT) scan were compared with the AAF and non-AAF groups.Results: Seventy patients who underwent C1 laminectomy without fusion were included in the study. The incidence of AAF was 14.2% (10/70). Multivariate analysis revealed that a large inferior facet angle (IFA, defined as the coronal inclination angle of the C1/2 facet as measured on CT) and the presence of subaxial ankylosis (bony ankylosis below C2 on CT) were independent risk factors for AAF. There were no significant differences in the subaxial cervical balance as measured on x-ray between the AAF and non-AAF groups (P > 0.05).Conclusion: The incidence of AAF after C1 laminectomy without fusion is not uncommon. Preoperative assessment using CT may identify patients at high risk of AAF.Level Of Evidence: 4. [ABSTRACT FROM AUTHOR]- Published

Study Design: Biomechanical investigation using cadaver spines.Objective: The aim of the present study was to assess the magnitude of the deflation effect after balloon kyphoplasty (BKP) or use of minimally invasive vertebral body stent (MIVBS) in in vitro biomechanical condition.Summary Of Background Data: BKP is a well-established minimally invasive treatment option for osteoporotic vertebral compression fractures. However, this technique can lead to a secondary height loss-known as the "deflation effect"-causing intrasegmental kyphosis and an overall alignment failure.Methods: The study was conducted on 24 human cadaveric vertebral bodies (T12-L5). After creating a compression fracture model, the fractured vertebral bodies were reduced by BKP (n = 12) or by MIVBS (n = 12) and then augmented with polymethyl methacrylate bone cement. Each step of the procedure was performed under fluoroscopic guidance and the results were analyzed quantitatively. Finally, the strength and stiffness of augmented vertebral bodies were measured by biomechanical tests.Results: Complete initial reduction of the fractured vertebral body height was achieved by both systems. Secondary loss of reduction after balloon deflation was significantly greater in the BKP group (2.36 ± 0.63 mm vs. 0.34 ± 0.43 mm in the MIVBS group; P < 0.05). Height gain was significantly higher in the MIVBS group (77.68% ± 11.46% vs. 34.87% ± 13.16% in the BKP group; P < 0.05). Increase in the kyphotic angle gain (relative to the preoperative kyphotic angle) was significantly more in the MIVBS group (95.60% ± 6.12% vs. 77.0% ± 4.94% in the BKP group; P < 0.05). Failure load was significantly higher in the MIVBS group (189% ± 16% vs. 146% ± 14%; P < 0.05). However, stiffness was not significantly different between the two groups.Conclusion: The deflation effect after BKP can be significantly decreased with the use of the MIVBS technique.Level Of Evidence: N/A.

Purpose: Balloon kyphoplasty (BK) has emerged as a popular method for treating osteoporosis vertebral compression fractures (OVCFs). In response to several shortcomings of BK, alternative methods have been introduced, among which is radiofrequency kyphoplasty (RFK). Biomechanical comparisons of BK and RFK are very sparse. The purpose of this study was to perform a biomechanical study in which BK and RFK are compared.Methods: Each of the two study groups comprised six specimens prepared from two functional spinal units (FSUs) cut from fresh-frozen cadaveric spines (3 of T9-T11 and 3 of T12-L2). VCFs (A1.2 type) were created in the middle VB of each of the FSUs, with a height loss of 30% of the VB. After that, the specimens were subjected to cyclic compression-compression loading. The following parameters were determined: range of motion (ROM), height of the middle VB, augmentation time, cement interdigitation and cement distribution. Also, the cement layer, the trabecular bone in the augmented VB and the bone-cement interface were examined for cracks. All of these parameters were determined at various stages, namely in the intact middle VB and after its fracture, cement augmentation and subject to the cyclic loading protocol.Results: Fractures caused a significant increase in median ROM and a significant reduction in the height of fractured VB. Cement augmentation significantly stabilized the fractures and led to partial height restoration. ROM and vertebral height, however, were not restored to the intact levels. Cyclic loading led to a further significant increase in ROM and a significant height reduction. There were no significant differences between BK and RFK in terms of any of these parameters.Conclusions: BK and RFK achieved similar results for fracture stabilization and restoration of the height of the fractured VB. RFK involved shorter cement augmentation time and less damage to the trabecular bone. [ABSTRACT FROM AUTHOR]- Published

Background Context: Bioresorbable calcium phosphate cement (CPC) may be suitable for vertebroplasty/kyphoplasty of osteoporotic vertebral fractures. However, additional targeted delivery of osteoinductive bone morphogenetic proteins (BMPs) in the CPC may be required to counteract the augmented local bone catabolism and support complete bone regeneration.Purpose: This study aimed at testing an injectable, poly (l-lactide-co-glycolide) acid (PLGA) fiber-reinforced, brushite-forming cement (CPC) containing low-dose bone morphogenetic protein BMP-2 in a sheep lumbar osteopenia model.Study Design/ Setting: This is a prospective experimental animal study.Methods: Bone defects (diameter 5 mm) were generated in aged, osteopenic female sheep and filled with fiber-reinforced CPC alone (L4; CPC+fibers) or with CPC containing different dosages of BMP-2 (L5; CPC+fibers+BMP-2; 1, 5, 100, and 500 µg BMP-2; n=5 or 6 each). The results were compared with those of untouched controls (L1). Three and 9 months after the operation, structural and functional effects of the CPC (±BMP-2) were analyzed ex vivo by measuring (1) bone mineral density (BMD); (2) bone structure, that is, bone volume/total volume (assessed by micro-computed tomography [micro-CT] and histomorphometry), trabecular thickness, and trabecular number; (3) bone formation, that is, osteoid volume/bone volume, osteoid surface/bone surface, osteoid thickness, mineralizing surface/bone surface, mineral apposition rate, and bone formation rate/bone surface; (4) bone resorption, that is, eroded surface/bone surface; and (5) compressive strength.Results: Compared with untouched controls (L1), CPC+fibers (L4) and/or CPC+fibers+BMP-2 (L5) significantly improved all parameters of bone formation, bone resorption, and bone structure. These effects were observed at 3 and 9 months, but were less pronounced for some parameters at 9 months. Compared with CPC without BMP-2, additional significant effects of BMP-2 were demonstrated for bone structure (bone volume/total volume, trabecular thickness, trabecular number) and formation (osteoid surface/bone surface and mineralizing surface/bone surface), as well as for the compressive strength. The BMP-2 effects on bone formation at 3 and 9 months were dose-dependent, with 5-100 µg as the optimal dosage.Conclusions: BMP-2 significantly enhanced the bone formation induced by a PLGA fiber-reinforced CPC in sheep lumbar osteopenia. A single local dose as low as ≤100 µg BMP-2 was sufficient to augment middle to long-term bone formation. The novel CPC+BMP-2 may thus represent an alternative to the bioinert, supraphysiologically stiff polymethylmethacrylate cement presently used to treat osteoporotic vertebral fractures by vertebroplasty/kyphoplasty.

Introduction:Symptomatic metastatic spinal disease is on the increase. Minimally invasive spinal surgery has been associated with a lower complication profile when compared to traditional open methods; however there is paucity of literature evaluating the place of percutaneous pedicle screw fixation (PPSF) in the management of spinal metastases. The purpose of the study is to assess the efficacy of Minimally Invasive Spine Surgery (MISS) using PPSF with or without mini-decompression in the management of symptomatic spinal metastases. Material and Methods:This is a single institution prospective study of 51 consecutive patients with metastatic spinal disease treated with PPSF. Patients presenting with pathological compression fractures and mechanical instability had PPSF, and those with radiological and/or clinical metastatic spinal cord compression (MSCC) underwent an additional mini-decompression. Data collected included patient demographics, Karnofsky’s performance status (KPS), pain scores and neurology. Other data included number and location of involved levels, number of instrumented levels, blood loss, accuracy of screw placement and complications. Results:Of the 51 patients, 49 could be successfully treated with MISS (26 females and 23 males). 26 patients (55%) required a mini-decompression. 27 patients (55%) had improvement in KPS by at least 10 points (p < 0.0005). Only 2 patients (4%) had a worsening of KPS, due to other coexisting problems. Six of the 13 patients improved their neurology by one Frankel grade following surgery and 95% reported improvement in pain. Mean blood loss was 92mls for the fixation only group and 222mls for those requiring mini-decompression, with no other differences between these two surgical groups. Screw positioning was excellent in 91%, with 98% having uncompromised bony hold. Only two patients required revision surgery for aseptic loosening. Conclusion:MISS using PPSF is a safe and reproducible technique that maintains or improves functional outcome in the vast majority of patients presenting with spinal metastases.

There are many causes of acute myelopathy including multiple sclerosis, systemic disease, and acute spinal cord compression (SCC). SCC should be among the first potential causes considered given the significant permanent loss of neurologic function commonly associated with SCC. This impairment can occur over a short period of time, and may be avoided through rapid and acute surgical intervention. Patients with SCC typically present with a combination of motor and sensory dysfunction that has a distribution referable to a spinal level. Bowel and bladder dysfunction and neck or back pain may also be part of the clinical presentation, but are not uniformly present. Because interventions are critically time-sensitive, the recognition and treatment of SCC was chosen as an ENLS protocol. [ABSTRACT FROM AUTHOR]

Cancer metastasis is a key event in tumor progression associated not only with mortality but also significant morbidity. Metastatic disease can promote end-organ dysfunction and even failure through mass effect compression of various vital organs including the spinal cord. In such cases, prompt medical attention is needed to restore neurological function, relieve pain, and prevent permanent damage. The three therapeutic approaches to managing metastatic spinal cord compression include corticosteroids, surgery, and radiation therapy. Although each may improve patients' symptoms, their combination has yielded the best outcome. In cancer patients with clinical suspicion of spinal cord compression, dexamethasone should be initiated followed by surgical decompression, when possible, and radiation. The latter becomes the preferred treatment in patients with inoperable disease. [ABSTRACT FROM AUTHOR]

Opinion Statement: Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established. Consultation with medical oncology, radiation oncology, and neurosurgery is imperative in order to facilitate a multidisciplinary approach. Although spine surgery is the most effective method for relief of cord compression and is necessary if there is spinal instability, surgery is only used in selected patients because most patients have a poor overall condition and short life expectancy. Radiation therapy, therefore, is the most commonly used therapy for patients with MESCC after surgical decompression or in patients who are not surgical candidates. Conventional fractionated radiation alone can achieve modest neurologic outcomes in selected radiosensitive tumors. Radiosurgery techniques which deliver intense focal irradiation to a delimited area with imaging guidance and contoured radiation delivery to the shape of the tumor have recently emerged as increasing effective treatments in MESCC, especially in radioresistant tumors. Stereotactic radiosurgery and different radiation technologies have been studied in recent clinical trials. [ABSTRACT FROM AUTHOR]- Published

Objectives: To evaluate the feasibility, safety, clinical, and radiologic outcomes of a minimally invasive direct lateral-approach corpectomy (MIDLaC) for decompression and stabilization of symptomatic metastatic spinal cord compression (MSCC). Methods: A retrospective study on a prospective cohort was conducted. Nineteen patients were consecutively treated with MIDLaC and posterior pedicle screw fixation between May 2012 and July 2014. Demographic information and radiologic outcomes including sagittal deformity correction and vertebral body height were recorded. Operative variables (operative duration, blood loss) and clinical variables (Tokuhashi score, mortality, complication rate, pain visual analogue scale [VAS], opioid usage, and Frankel grade) were recorded and analyzed. Results: All nineteen patients (mean age: 67.6 ± 12.7 years) successfully underwent MIDLaC with excellent neural decompression. Operative duration was 188.4 ± 30.3 minutes for single-level MIDLaC and 327.2 ± 71.9 minutes for multilevel surgery (p < 0.0001). Mean blood loss per spinal level was 390.8 mL with a decrease to 102.3mL excluding renal cellMSCC. A total of 47.4% of patients had a Tokuhashi score of 0 to 8. There was one approach-related complication and one perioperative mortality. The overall complication rate was 15.8% (n = 3) with no postoperative wound infections. Kaplan-Meier survival estimates at 6 months were 0.50. Overall, 31.6% of patients improved by one or more Frankel grades, and no patients demonstrated worsening neurology postoperatively. VAS was significantly improved postoperatively (p < 0.05). Vertebral body height was significantly increased (þ7.6 ± 8.1 mm; p = 0.002), with improvements in lumbar lordosis (8.3 ± 7.3 degrees) and thoracic kyphosis (2.4 ± 7.1 degrees) postoperatively. Conclusion: MIDLaC is a safe and feasible palliative approach in the management of MSCC with encouraging early clinical outcomes. Further prospective studies are required to define the role of MIDLaC in the management of MSCC vis-à-vis other mini-open or minimally invasive techniques. [ABSTRACT FROM AUTHOR]

Transcripts were analysed using a framework approach.Results: Time emerged as an overarching theme within the framework of four time points: past, present, near future and distant future. Themes included getting home, challenges at home, community support, getting back to normal, in limbo, long-term goals and coping strategies.Conclusion: Getting to a level of coping at home after discharge following MSCC can take time. Services need to address this so that patients can live well within the limitations they face. [ABSTRACT FROM AUTHOR]- Published

Introduction: Radiotherapy alone still is the most commonly delivered treatment modality for metastatic spinal cord compression (MSCC). MSCC is an emergency situation, which requires treatment as soon as possible. When radiotherapy is performed with the most commonly used approach 10 × 3 Gy (30 Gy in 10 fractions) over 2 weeks, the question has been asked whether an overall treatment time (OTT) of 14-15 days including two weekends without irradiation leads to worse outcomes than OTT of 12 days (beginning of radiotherapy on a Monday resulting in only one weekend break)?Methods: A total of 412 patients with MSCC were included in this retrospective study. Ninety-two patients receiving 10 × 3 Gy over 12 days were compared to 320 patients with an OTT of 14-15 days. Ten additional factors were investigated.Results: On multivariate analysis, functional outcome was associated with tumour type (P < 0.001), time developing motor deficits (P < 0.001), ambulatory status (P = 0.018) and performance score (P < 0.001); OTT had no significant impact (P = 0.40). On univariate analysis of local control of MSCC (freedom from recurrence in irradiated spinal parts), no factor was significant including OTT (P = 0.66). On multivariate analysis, visceral metastases (P < 0.001), tumour type (P < 0.001), time developing motor deficits (P < 0.001), ambulatory status (P < 0.001) and performance score (P < 0.001) were associated with survival, OTT not even on univariate analysis (P = 0.55).Conclusions: Since an OTT of 14-15 days had no negative impact on outcomes compared to 12 days, compensation in form of an additional radiation fraction or continuation of radiotherapy during weekends is not required, if radiotherapy cannot be started on a Monday.

Design: Retrospective cohort.Purpose: The aim of this study is to evaluate the effectiveness of percutaneous short fixation (PSFx) plus kyphoplasty (BP) for thoracolumbar fractures.Methods: Thirty-six consecutive selected patients, aged 59 ± 17 years, with fresh single thoracolumbar A2, A3, and B2 AO-type fracture, received PSFx plus BP. The primary outcomes pain, and vertebral body deformity; and the secondary outcomes screw malposition, facet violation, PMMA leakage, adjacent segment degeneration (ASD) and loss of correction were evaluated. The f/up was 31 ± 7 months.Results: Pain and kyphosis decreased and vertebral body heights increased significantly postoperation. PMMA leakage occurred in five cases; 6 (4 %) screws were grades III malpositioned in relation to pedicle; facet violation occurred in 8 (5.5 %) facets; loss of kyphosis correction was 3.68°; ASD occurred in two cases; interfacet fusion in ten (28 %) patients; Three patients were reoperated for different reasons.Conclusions: PSFx plus BP for thoracolumbar fractures reduces significantly spinal deformity and pain with few complications.

Objective Spinal arachnoid webs are a rare variant of spinal arachnoid cysts where 1 or multiple focal membranes of arachnoid tissue obstruct the subarachnoid space. Only 11 prior cases of arachnoid webs have been reported in the literature. We present a series of 3 consecutive cases of arachnoid webs from our institution and review the literature on this rare condition to provide recommendations for its management. Methods Retrospective chart review was performed for 3 consecutive cases of intradural arachnoid webs causing spinal cord compression at our institution, with inconclusive preoperative imaging, treatment with surgical decompression, and resection. There were no external sources of funding. Results Our cases occurred dorsally in the thoracic spine and were associated with syringomyelia. Preoperative magnetic resonance imaging, computed tomography myelography, and cine magnetic resonance imaging were inconclusive, and the definitive diagnosis was made with intraoperative ultrasound. Patients underwent laminectomies and resection of arachnoid webs. Unique from prior reports of arachnoid webs, the webs in the present cases were composed of multiple septated longitudinal membranes rather than a transverse band. All patients had improvement of presenting symptoms postoperatively. Conclusions Intradural arachnoid webs causing spinal cord compression are rare. Preoperative imaging may be inconclusive. Because of the septated longitudinal nature of the visualized membranes, we propose a 1-way valve mechanism of cerebrospinal fluid obstruction causing gradual cord compression and resultant syringomyelia.

Background: The contribution of preoperative embolization in reducing intraoperative blood loss and its clinical importance are unclear. So, we aimed to compare the perioperative clinical outcomes based on whether preoperative embolization was performed and assess the role and safety of preoperative embolization in metastatic spinal cord compression (MSCC) patients. Methods: We enrolled 52 patients (men, 37; women, 15) who underwent palliative decompression for MSCC. Demographic data, neurologic status, surgery-related data (operation time, estimated blood loss, and transfusion), complications, and survival time were recorded. Patients were categorized based on whether they received preoperative embolization: groups E (embolization) (n = 18) and NE (non-embolization) (n = 34) and the clinical parameters were compared. Subgroup analysis was performed specifically for cases of hypervascular tumors (23/52, 44%). Results: The transfusion degree was greater in the NE group (4.6 pints) than in the E group (2.5 pints, P = 0.025); the other parameters did not differ between the groups. However, massive bleeding (>2000 mL) was more frequent in the NE group (10/34) than in the E group (0/18, P = 0.010). Subgroup analysis indicated that intraoperative blood loss was greater in the NE group (1988 mL) than in the E group (1095 mL, P = 0.042) in hypervascular tumor patients. Although massive bleeding was more frequent among hypervascular tumor patients, 3 patients with non-hypervascularized tumors also exhibited massive bleeding (P = 0.087). Conclusions: Intraoperative blood loss and perioperative transfusion can be reduced by preoperative embolization in MSCC patients. Neurologic recovery, operation time, and complications did not differ according to the application of embolization. As preoperative embolization is relatively safe and effective for controlling intraoperative bleeding without any neurologic deterioration, it is highly recommended for hypervascular tumors. Moreover, it may also be effective for non-hypervascular tumors as massive bleeding may be noted in some cases. [ABSTRACT FROM AUTHOR]

Background: Abscesses in the neck region can result from infection associated with injection of drugs into the neck muscles. To our knowledge, there have been no reports of osteomyelitis of the cervical vertebra and spinal cord compression secondary to an abscess in the neck. This case report describes the findings in a 9.5-month-old heifer with an abscess of the cervical spine secondary to injection site infection. Case presentation: The main clinical findings were swelling on the left side of the neck, proprioceptive deficits in all limbs and generalised ataxia. The ultrasonographic examination of the swelling showed an abscess. Radiographs showed a well-defined lytic lesion in 5th cervical vertebra (C5). Postmortem examination revealed an intramuscular encapsulated abscess on the left side of the neck at the level of C5. The abscess had invaded the vertebral canal and caused marked compression of the spinal cord. Conclusions: Injection technique is critical for the prevention of problems such as those described in this report. Sterile hypodermic needles must be used, and the volume of drug per injection site limited to 10-15 ml in young cattle. [ABSTRACT FROM AUTHOR]

Purpose: Metastatic epidural spinal cord compression (MESCC) often requires anterior-posterior decompression and stabilization. To reduce approach-related complications, single-stage posterolateral vertebrectomy and 360° fusion is often performed. However, a sufficient reduction of kyphotic deformity through this approach has not been reported. The purpose of this study is to investigate the efficacy of kyphotic deformity reduction by this approach in MESCC.Methods: A retrospective analysis and chart review was performed for 14 consecutive patients who underwent a vertebrectomy and decompression from a posterolateral approach. Anterior mesh stabilization of the ventral column is used as hypomochlion for the posterior compression manoeuvre, which leads to reduction of the kyphotic deformity.Results: Pre-operative back pain was 7.2 on a visual analogue scale. Back pain was reduced to 4.4 at discharge and 2.0 at the latest follow-up with a mean follow-up of 12 months (p < 0.001). The Frankel score remains constant or improved from D to E. Radiological segmental kyphosis was corrected from a mean of 16° to 4° (p < 0.001) post-operatively with a loss of 3° at the final follow-up, but still with significant corrections compared with the pre-operative measurements (p < 0.003).Conclusion: Single-stage posterolateral vertebrectomy and reconstruction is a safe and less invasive approach that allows a sufficient reduction of hyperkyphosis and preservation of neurological function in patients with MESCC. This approach is an efficient alternative to anterior-posterior fusion with good pain reduction and improved sagittal profile. [ABSTRACT FROM AUTHOR]- Published

Calcification of the ligamentum flavum (CLF) can cause myelopathy due to spinal cord compression. Only several cases in Caucasian patients have been described. Neurological deterioration can only be stopped by surgical decompression. We report a 63-year-old Caucasian woman presenting with progressive pins-and-needles sensations in both hands, worsened by painful paresthesia in both lower extremities. MRI showed a dorsal compressive mass extending from C2 to Th3 vertebrae with myelopathy at the level of C6. A laminectomy was performed, which improved clinical symptoms. Histological examination showed CLF. Early recognition of CLF and early spinal cord decompression are needed to improve neurological outcome. [ABSTRACT FROM AUTHOR]

Intervertebral disc herniation is a common cause of spinal cord compression, especially for the thoracic and thoracolumbar spinal cord, which has limited buffer space in the spinal canal. Spinal cord compression usually causes decreased sensation and paralysis of limbs below the level of compression, urinary and fecal incontinence, and/or urinary retention, which brings great suffering to the patients and usually requires surgical intervention. Thoracotomy or abdominothoracic surgery is usually performed for the thoracolumbar cord compression caused by hard intervertebral disc herniation. However, there is high risk of trauma and complications with this surgery. To reduce the surgical trauma and obtain good visibility, we designed athoracic endoscopic-assisted mini-open surgery for thoracic and thoracolumbar disc herniation, and performed this procedure on 10 patients who suffered from hard thoracic or thoracolumbar spinal cord compression. During the procedure, the thoracic endoscopy provided clear vision of the surgical field with a good light source. The compression could be fully exposed and completely removed, and no nerve root injury or spinal cord damage occurred. All patients achieved obvious recovery of neurological function after this procedure. This technique possesses the merits of minimal trauma, increased safety, and good clinical results. The aim of this study is to introduce this thoracic endoscopic-assisted mini-open surgery technique, and we believe that this technique will be a good choice for the thoracic and thoracolumbar cord compression caused by hard intervertebral disc herniation.

Purpose: To compare the short- and long-term clinical outcomes, operation times, restoration rate, dosage of polymethylmeth-acrylate (PMMA) injected, complications and X-rays exposure frequency between unilateral and bilateral kyphoplasty approaches for the treatment of OVCF.Study Design: Systematic review and meta-analysis.Methods: Randomized or non-randomized controlled trials published up to April 2015 that compared the unilateral and bilateral PKP for the treatment of OVCF were acquired by a comprehensive search in the Cochrane Controlled Trial Register, PubMed, MEDLINE, EMBASE, Web of Science, OVID. Exclusion criteria were patients with neoplastic etiology (metastasis or myeloma), infection, neural compression syndrome, invasive and degenerative disease, traumatic fracture, re-operation, neurological deficits, significant scoliosis and spinal stenosis. The main end points included: operation times, the short- and long-term postoperative Visual Analogue Scale (VAS) scores, the short-term postoperative Oswestry Disability Index (ODI), restoration rate, dosage of PMMA injected, cement leakage, X-ray exposure frequency and postoperative adjacent-level fractures.Results: A total of 8 studies involving 428 patients were included in the meta-analysis. The mean operative time was shorter in the unilateral groups compared with the bilateral groups [P < 0.05, weighted mean difference (WMD) -19.74 (-30.56, -8.92)]. There was no significant difference in the short-term postoperative VAS scores [P > 0.05, WMD 0.03 (-0.34, 0.40)], the long-term postoperative VAS scores between them [P > 0.05, WMD 0.01 (-0.42, 0.45)] and the short-term postoperative ODI [P > 0.05, WMD -0.33 (-2.36, 1.69)] between the two groups. The unilateral approaches required significantly less dosage of PMMA than the bipedicular approaches did [P < 0.05, WMD -1.56 (-1.59, -1.16)]. The restoration rate in the bilateral groups was higher than the unilateral groups [P < 0.05, WMD -7.82 (-12.23, -3.41)]. There was no significant difference in the risk ratio of cement leakage [P > 0.05, RR 0.86 (0.36, 2.06)] and postoperative adjacent-level fractures [P > 0.05, RR 0.91 (0.25, 3.26)] between the two methods. The mean X-ray exposure frequency in the unilateral groups was greater than the bilateral groups [P < 0.05, WMD -5.69 (-10.67, -0.70)].Conclusions: A definitive verdict could not be reached regarding which approach is better for the treatment of OVCF. Although unilateral PKP was associated with shorter operative time, less X- ray exposure frequency and dosage of PMMA than bilateral PKP. There was no apparent difference in the short- and long-term clinical outcomes and complications between them. However, bilateral PKP approaches were higher than unilateral PKP in term of the restoration rate. But on account of lack of some high-quality evidence, we hold that amounts of high-quality randomized controlled trials should be required and more complications should be analysed to resolve which surgical approach is better for the treatment of OVCF in the future.

Metastatic spinal cord compression (MSCC) is compression of the spinal cord or caudal equina as a result of the progression of metastatic lesions within the vicinity of the spinal cord. The consequences are very severe with loss of neurological function and severe pain. The standard treatment is surgical intervention followed by radiotherapy or radiotherapy alone in rising life expectancy of cancer patients, prevention of irreversible neurological injury, pain treatment, maintain patients' mobility, function and independence. In RO clinics Interprofessional collaborative practice (IPC) becomes essential in rising life expectancy of cancer patients. Although Interprofessional education (IPE) has been recognized to improve health care delivery and patient outcomes yet IPE and IPCP data in RO of MSCC) are lack and limited. This qualitative study primarily aimed to appraisal of IP practice in radiation oncology of MSCC. A Survey was conducted from July2021 to April 2022 with radiation oncologists professions across two radiation oncology clinics affiliated in Dar –Es salaam. On appointment Interviews were recorded, de-identified, and transcribed verbatim. Resulting transcripts were analyzed using thematic analysis. Seventy interviews were performed with radiation oncologist's professions. Following thematic analysis 4 themes were identified: (1) challenges associated with management of the radiation oncology clinic to the patients with highly needs, (2) potential impact IP in MSCC as special cases (3) current situation of IPE in radiation oncology settings and (4) creating an IPE initiatives in radiation oncology. This study hypothesized that misunderstanding professionals' roles can lead to communication breakdown and less efficient IN RO clinics. This study suggests Well-structured IPE Exposure for radiation oncologists professions can be an opportunities to professions working in palliative care environment. [ABSTRACT FROM AUTHOR]

Study Design. Review article. Objective. The article mainly reviewed the development and current situation of percutaneous kyphoplasty (PKP) in China, aiming to introduce native efforts and progress for PKP procedure on the exploring road. Summary of Background Data. Since PKP was first reported in China in 2002, Chinese orthopedic researchers have performed lots of clinical applications and studies on the treatment of osteoporotic vertebral compression fracture, spinal metastatic tumor, hemangioma, myeloma, vertebral nonunion, and so on. Methods. We reviewed the papers on PKP published by native researchers in English and Chinese via Pubmed, EMBASE, the Scopus database, and a series of Chinese databases including Wanfang Data, China National Knowledge Infrastructure (CNKI), and the China Science and Technology Journal Database. The large sample capacity researches, convictive systematic analysis, and overviews were mainly elected as convictive evidence to describe the overall situation of clinical outcomes, complications, and the various technical aspects used to improve conventional surgical management and clinical applications of PKP in China. Results. Until October 2015, 211 articles in English and 2352 studies in Chinese about PKP were reported by 1443 Chinese institutions from 22 provinces around China. More than 50976 patients reported through published articles have received the treatment of PKP. With the technique gradually improved, including puncture, bone cement infusion, vertebral expander instruments, diagnosis, and treatment of special type of vertebral fractures, PKP is performed with the better efficacy and less complication. Conclusion. With the progression of minimally invasive spinal surgery around the world, PKP in China has been performed with a trend towards a rapid, safe, and effective treatment. Digital, real-time and artificial intelligence are the directions of future development of PKP. [ABSTRACT FROM AUTHOR]

Secondary damage after acute spinal cord compression injury (SCCI) exacerbates initial insult. Nuclear factor kappa-B (NF-κB)-p65 activation is involved in SCCI deleterious effects. Agmatine (Agm) showed neuroprotection against various CNS injuries. However, Agm impact on NF-κB signaling in acute SCCI remains to be investigated. The present study compared the effectiveness of Agm therapy and decompression laminectomy (DL) in functional recovery, oxidative stress, inflammatory and apoptotic responses, and modulation of NF-κB activation in acute SCCI rat model. Rats were either sham-operated or subjected to SCCI at T8–9, using 2-Fr. catheter. SCCI rats were randomly treated with DL at T8–9, intraperitoneal Agm (100 mg/kg/day), combined (DL/Agm) treatment or saline ( n = 16/group). After 28-days of neurological follow-up, spinal cords were either subjected to biochemical measurement of oxidative stress and inflammatory markers or histopathology and immuno-histochemistry for NF-κB-p65 and caspase-3 expression ( n = 8/group). Agm was comparable to DL in facilitating neurological functions recovery, reducing inflammation (TNF-α/interleukin-6), and apoptosis. Agm was distinctive in combating oxidative stress. Agm neuroprotective effects were paralleled with inhibition of NF-κB-p65 nuclear translocation. Combined pharmacological and surgical interventions were proved superior in functional recovery. In conclusion, present research suggested a new mechanism for Agm neuroprotection in rats SCCI through inhibition of NF-κB activation. [ABSTRACT FROM AUTHOR]

Objective Improvements in cancer treatment have resulted in an increased number of patients with metastatic spinal cord compression ( MSCC). Because patients with MSCC often have a limited expected survival time, maintenance of a high functional level and quality of life are important. However, there is limited information about health-related quality of life ( HRQoL) in patients with MSCC. The aim of this study was to examine the feasibility of routine assessment of HRQoL based on the Euroqol-5 dimensions ( EQ-5D) questionnaire in a cohort of patients consecutively admitted for evaluation of acute symptoms of MSCC. Methods From 1 January to 31 December 2011, 544 patients diagnosed with acute symptoms of MSCC were consecutively enrolled in a cohort study. All patients were evaluated through a centralized referral system at one treatment facility. Data were prospectively registered, the variables age, sex, primary oncologic diagnosis, Tokuhashi Revised score, EQ-5D score and treatment modality being recorded on admission. The study patients were treated conservatively with radiotherapy alone or with surgery and subsequent radiotherapy. The EQ-5D questionnaire was administered on admission (baseline) and 6, 12, 26 and 52 weeks after admission. Response rates, completion rates and HRQoL scores were analyzed by relevant subgroups. Response rates were based on all questionnaires returned regardless of whether or not they had been completed, whereas completion rates were based on fully completed questionnaires (i.e., containing responses to all five questions. Results The mean age was 65 years (range, 20-95 years); 57% of the patients were men. The overall response rate to the Euroqol-5 dimensions ( EQ-5D) questionnaires was 84% and the overall completion rate 72%. At baseline, mean EQ-5D scores were significantly lower for patients treated with surgery and subsequent radiotherapy 0.28 (95% CI, 0.19-0.36) than for those treated with radiotherapy alone 0.42 (95% CI, 0.38-0.46). At the one-year follow-up, the mean EQ-5D scores had improved to 0.71 (95% CI, 0.64-0.77) for patients treated with surgery and subsequent radiotherapy and 0.63 (95% CI, 0.56-0.70) for patients treated with radiotherapy alone. Conclusions Measurement of HRQoL in patients consecutively admitted for evaluation of acute symptoms of MSCC is feasible and detects significant changes over time between treatment modalities and different strata of expected survival.

Kyphoplasty is a minimally invasive spine surgical procedure performed to stabilize and treat the pain caused by a spine compression fracture. Complications are rare with kyphoplasty and include cement extrusion into the vertebral canal leading to spinal cord or nerve root compression. Herein, the authors present a case of a 72-year-old woman who presented with symptoms of a right L2 radiculopathy after a kyphoplasty procedure. Computed tomography imaging showed leakage of the kyphoplasty cement into the neural foramen above and medial to the right L2 pedicle. A transforaminal endoscopic surgical approach was used to remove the cement and decompress the L2 nerve. The patient's postoperative clinical course was uneventful. Clinicians should be aware that for the treatment of complications to vertebroplasty and kyphoplasty procedures, minimally invasive transforaminal endoscopic surgery is one option to avoid the destabilizing effects of laminectomy and facetectomy.

A 14 mo old female neutered Doberman pinscher was evaluated for difficulty in rising, a wide based stance, pelvic limb gait abnormalities, and cervical pain of 2 mo duration. Neurologic examination revealed pelvic limb ataxia and cervical spinal hyperesthesia. Spinal reflexes and cranial nerve examination were normal. The pathology was localized to the C1- C5 or C6-T2 spinal cord segments. Computed tomography (CT) findings indicated bony proliferation of the caudal articular processes of C6 and the cranial articular processes of C7, resulting in bilateral dorsolateral spinal cord compression that was more pronounced on the left side. A limited dorsal laminectomy was performed at C6-C7. Due to progressive neurological deterioration, follow-up CT examination was performed 4 days postoperatively. At the level of the laminectomy defect, a subfacial seroma had developed, entering the spinal canal and causing significant spinal cord compression. Under ultrasonographic guidance a closed-suction wound catheter was placed. Drainage of the seroma successfully relieved its compressive effects on the spinal cord and the patient's neurological status improved. CT was a valuable tool in assessing spinal cord compression as a result of a postoperative subfascial seroma. Minimally invasive application of a wound catheter can be successfully used to manage this condition. [ABSTRACT FROM AUTHOR]

Background Context: A number of studies have reported favorable surgical results for metastatic spinal tumors from various solid tumors. However, there are few data available on metastatic spinal cord compression (MSCC) from lung cancer despite its considerable frequency.Purpose: The study aims to present the functional outcomes, survival time, and complications after surgical treatment for MSCC from non-small cell lung cancer (NSCLC).Study Design/setting: This is a longitudinal observational study.Patient Sample: The study includes 50 patients who had neurologic deficit and underwent surgical treatment for MSCC from NSCLC.Outcome Measures: The Eastern Cooperative Oncology Group performance status (ECOG-PS), ambulatory status, overall survival, factors associated with survival time, and perioperative complications were analyzed.Methods: The postoperative changes of ECOG-PS and ambulatory status were assessed. The factors affecting postoperative ambulatory status were evaluated using logistic regression analysis. Survival time was calculated using the Kaplan-Meier method. To identify the prognostic factors, log-rank test and Cox hazards regression model were used for univariate and multivariate analyses, respectively. Major complications within postoperative 30 days and mortality rate were recorded.Results: The study cohort consisted of 27 males and 23 females with a mean age of 58.0±11.3 years at the time of surgery. An ECOG-PS improvement by at least one grade was observed in 33 of 50 cases (66.0%). Among 39 patients who were not ambulatory before surgery, 23 patients (59.0%) regained ambulatory ability after surgery. Patients who were preoperatively ambulant and those who underwent surgery within 72 hours from neurologic deficit had an increased chance of postoperative ambulation. The median for overall survival after surgery was 5.2 months. Five prognostic factors were identified on univariate analysis: time from neurologic deficit, responsiveness to preoperative chemotherapy, postoperative chemotherapy, postoperative ECOG-PS, and postoperative ambulatory status. Multivariate analysis revealed that time to neurologic deficit (risk ratio [RR]: 2.28, p=.023), postoperative chemotherapy (RR: 6.58, p<.001), and postoperative ECOG-PS (RR: 2.73, p=.040) were independent prognostic factors of survival time. Major complications developed in 34.0% of patients (17 of 50), and the 30-day mortality rate was 10.0% (5 of 50).Conclusions: Functional improvements were observed through surgical treatment even with relatively high complication rates for MSCC from NSCLC. Earlier surgical treatment could act as an adjuvant therapy for prolonging survival by improving functional status. [ABSTRACT FROM AUTHOR]- Published

Current treatment standard for patients with metastatic spinal cord compression (MSCC) is decompressive surgery followed by radiotherapy. Stereotactic radiosurgery (SRS) could be considered a treatment option for MSCC for patients with minor neurologic deficits. If SRS is safely and effectively delivered with equivalent functional outcome, the patients would avoid the risks associated with an invasive procedure. This paper presents the design of a non-inferiority clinical trial evaluating the safety, tolerability and feasibility of SRS vs. current standard treatment for patients with MSCC. Patients fulfilling inclusion criteria will be randomized 1:1 to each arm. The primary endpoint is ability to walk six weeks after treatment. Secondary endpoints are levels of pain, bladder control, quality of life, response rate, toxicity and number of treatment days. 65 patients in each arm are required for the power of 89% to detect a clinically relevant inferior outcome.

Objective: To investigate whether there was parity between treatment fields localized by radiographers and clinicians, by comparing geographical variations and hence determining the feasibility of a radiographer-led service. Methods: 23 patients with metastatic spinal cord compression (MSCC) were prospectively sampled. Four radiographers not involved in the original planning performed localization on each patient. The 92 localizations that they determined were compared with the clinician-approved fields. Agreement was defined as =0.5?cm between field length, width and three isocentre co-ordinates. To be feasible, agreement was required in a minimum of 97% of the cases. The potential time saved with a radiographer-led approach was also recorded. Results: Agreement between clinicians and radiographers was 97.8%. For all field parameters, the average differences were <0.3 cm and were significantly different from the 0.5-cm median (p < 0.0001) that would establish no agreement using Wilcoxon signed-rank test. The average (range) delay awaiting clinician approval was 54 min (4-141 min). Conclusion: Strong agreement between radiographer and clinician localizations was established. It was also highlighted that time could be saved in the patient's pathway by removing the need to wait for clinician approval. We believe this supports a radiographer-led service. Advances in knowledge: This article is novel, as it is the first known comparison between clinicians and radiographers in the localization of MSCC radiotherapy. These data show the feasibility of introducing radiographer-led practice and a methodology that could be potentially transferred to investigate the localization parity for other treatment sites.

Patients with cancer frequently present to hospital as an emergency admission acutely unwell. Patients can suffer from complications of the cancer itself, or significant adverse effects/toxicities related to their cancer therapy . Alternatively, the initial presentation of the malignancy may be through a hospital admission, and the cancer can frequently be widespread and with a poorer prognosis. Patients are often admitted under general physicians, away from their comprehensive cancer care centre or oncologists. Without specialist input or staff adhering to most appropriate pathways, the management of these complicated conditions may be difficult, with patients sometimes having unnecessary and painful investigations and prolonged hospital stays. To address these issues the concept of an acute oncology service has recently evolved. This is a developing sub-specialty that aims to improve the care of cancer patients presenting acutely to hospital at a devastating time in their lives. This article will explore the literature to describe the recent development of the acute oncology model, and consider different methods for the delivery of this service. [ABSTRACT FROM AUTHOR]

Background: Metastatic spinal cord compression is a disastrous consequence of non-small-cell lung cancer (NSCLC). There have been few studies of the outcomes or prognostic factors in patients with metastatic spinal cord compression from NSCLC treated with surgery and adjuvant therapies. Methods: From 2002 to 2013, 116 patients with metastatic spinal cord compression from NSCLC treated with surgery and adjuvant therapies were enrolled in this retrospective analysis. Kaplan-Meier methods and Cox regression analysis were used to estimate overall survival and identify prognostic factors for survival. Results: Multivariate analysis suggested that the Eastern Cooperative Oncology Group performance status (ECOG-PS), preoperative and postoperative Frankel scores, postoperative adjuvant radiation therapy, and target therapy were independent prognostic factors. Ninety patients died at a median of twelve months (range, three to forty-sevenmonths) postoperatively, and twenty-six patients were still alive at the time of final follow-up (at a median of fifteen months [range, five to fifty-four months]). Conclusions: The complete disappearance of deficits in spinal cord function after surgery was the most robust predictor of survival. Adjuvant radiation therapy and target therapy were also associated with a better prognosis. [ABSTRACT FROM AUTHOR]
