Abstract
The optimal timing of surgery for cervical spinal cord injuries (SCI) and its impact on neurological recovery continue to be subjects of debate. This systematic review and meta-analysis aims to consolidate and assess the existing evidence regarding the efficacy of ultra-early decompression surgery in improving clinical outcomes after cervical SCI. A search was conducted in PubMed, Embase, Cochrane, and CINAHL databases from inception until September 18, 2023, focusing on human studies. The groups were categorized into ultra-early decompression (decompression surgery ≤ 5 hours post-injury) and a control group (decompression surgery between 5-24 hours post-injury). A random effects meta-analysis was performed on all studies using R Studio. Outcomes were reported as effect size (OR, treatment effect, and 95% CI. Of the 140 patients, 63 (45%) underwent decompression ≤ 5 hours, while 77 (55%) underwent decompression > 5 hours post-injury. Analysis using the OR model showed no statistically significant difference in the odds of neurological improvement between the ultra-early group and the early group (OR = 1.33, 95% CI: 0.22-8.18, p = 0.761). This study did not observe significant neurological improvement among cervical SCI patients who underwent decompression within five hours. Due to the scarcity of literature on the ultra-early decompression of cervical SCI, this study underscores the necessity for additional investigation into the potential benefits of earlier interventions for cervical SCI to enhance patient outcomes.

Abstract
CONTEXT Compared with younger traumatic spinal cord injury (TSCI) patients, the elderly had longer delays in admission to surgery, higher proportion of incomplete injury, and longer hospital stays. However, in China, the country with the largest number of TSCI patients, there have been no large-scale reports on their age differences. OBJECTIVES To explore the age-based differences among TSCI inpatients, focusing on the demographic and clinical characteristics, treatment status, and economic burden. METHODS We collected the medical records of 13,334 inpatients with TSCI in the 30 hospitals of China, from January 1, 2013 to December 31, 2018. Trends are expressed as annual percentage changes (APCs) and 95% confidence intervals (CIs). RESULTS A total of 13,334 inpatients were included. Both the number and proportion of the elderly showed an increasing trend. The APC of the number and proportion in patients ≥85 years were 39.5% (95% CI, 14.3 to 70.3; P < 0.01) and 30.5% (95% CI, 8.6 to 56.9; P < 0.01), respectively. Younger patients were more likely to undergo decompression surgery, and older patients were more likely to receive high-dose methylprednisolone sodium succinate/methylprednisolone (MPSS/MP). Of the patients ≥85 years, none underwent decompression surgery within 8 h, and only 1.4% received a high dose of MPSS/MP within 8 h after injury. Elderly patients had lower hospitalization costs than younger. The total and daily medical costs during hospitalization of patients ≥85 years were 8.06 ± 18.80 (IQR: 5.79) and 0.61 ± 0.73 (IQR: 0.55) thousands dollars, respectively. CONCLUSIONS As the first study to focus on age differences of TSCI patients in China, this study found many differences, in demographic and clinical characteristics, treatment status, and economic costs, between older and younger TSCI patients. The number and proportion of elderly patients increased, and the rate of early surgery for elderly patients is low.

Abstract
Early surgical decompression within 24 hours for traumatic spinal cord injury (SCI) is associated with improved neurological recovery. However, the ideal timing of decompression is still up for debate. The objective of this study was to utilize our retrospective single-institution series of ultra-early (<5 hours) decompression to determine if ultra-early decompression led to improved neurological outcomes and was a feasible target over previously defined early decompression targets. Retrospective data on patients with SCI who underwent ultra-early (<5 hours) decompression at a level one metropolitan trauma center were extracted and collected from 2015-2018. American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade improvement was the primary outcome, with ASIA Motor score improvement and complication rate as secondary outcomes. Four individuals met the criteria for inclusion in this case series. All four suffered thoracolumbar SCI. All patients improved neurologically by AIS grade, and there were no complications directly related to ultra-early surgery. Given the small sample size, there was no statistically significant difference in outcomes compared to a control group who underwent early (5-24 hour) decompression in the same period. Ultra-early decompression is a feasible and safe target for thoracolumbar SCI and may lead to improved neurological outcomes without increased risk of complications. This case series can help create the foundation for future, larger studies that may definitively show the benefit of ultra-early decompression.

NORTH AMERICAN SPINE SOCIETY JOURNAL 2023; 16:100285. [PMID: 37942310 PMCID: PMC10628804 DOI: 10.1016/j.xnsj.2023.100285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/29/2023] [Accepted: 10/01/2023] [Indexed: 11/10/2023]
Abstract
Background The impact of the timing of surgery on neurological recovery in thoracolumbar spinal cord injuries (tSCI) is still a subject of discussion. Accumulating evidence is supporting early decompression (<24 hours) following tSCI. However, the potential advantages of earlier decompression remain uncertain. This systematic review and meta-analysis summarize and analyze the current evidence on the effectiveness of ultra-early decompression surgery on clinical outcomes following tSCI. Methods A search was conducted in the electronic databases Medline, Embase, Scopus, and Web of Science from their inception until May 2022 for human studies. Groups were stratified into ultra-early (surgery within 8 hours of injury) vs control group operated >8 hours of injury. The authors included the study data from their institutional case series of thoracolumbar spinal cord injury from 2015 to 2018. An arm-based meta-analysis was performed on all studies using the R Studio. For studies that qualified, a contrast-based meta-analysis was also performed with a standardized mean difference (SMD). Outcomes were reported as effect size, treatment effect, and effect difference, all with 95% confidence intervals (CI). Results Of the 133 patients, 74.4% patients were male. 76 (57.1%) underwent decompression ≤8 hours, while 57 (42.9%) underwent decompression >8 hours from injury. Quantitative analysis using the SMD model showed a significant difference in mean AIS improvement in the ultra-early group (Effect size 1.15 [0.62-1.67], p<.0001). On arm-based meta-analysis, a statistically significant treatment effect was found for the ultra-early arm (1.25 [0.91-1.67]), while > 8-hour arm did not show significance (0.30 [-0.08-0.71]). There was a statistically significant effect difference between the two arms (0.96 [0.49-1.48]). Conclusions This study observed a significant improvement in the mean AIS score in patients undergoing decompression within 8 hours of tSCI. Given the scant literature regarding ultra-early decompression of tSCI, this study solidifies the need to further explore the role of early interventions for tSCIs to improve patient outcomes.

Abstract
Debate regarding timing of surgical decompression after spinal cord injury continues. Recent evidence indicates that early decompression improves neurological outcomes. However, little investigation has been performed regarding how it affects one's hospitalization in a geriatric cohort. 8,999 cases of traumatic SCI who underwent surgical decompression (2002-2011, age 65 + years) within the Nationwide Inpatient Sample were included in univariate and multivariate analyses. Univariate analysis shows that early decompression is more cost effective ($88,564.00 vs $107,849.00, p < 0.0005) and is associated with shorter length of stay (LOS) (8.00 ± 16.15 vs 12.00 ± 15.93 days, p < 0.0005) when compared to late decompression. In multivariate analysis, early decompression continued to be associated with a shorter LOS, though cost was no longer statistically different. Early decompression had less odds of surgical site infection, vasopressor use, decubitus ulcers, but higher odds of cardiac complications, acute renal failure, transfusions and hardware complications. Spinal level of SCI did not affect timing of surgery. Vertebral column fracture did not influence cost or length of stay. In summary, the complex mix of results regarding inpatient complications highlight the innumerable variables and complex decision making that involves surgical treatment of SCI, especially within a susceptible geriatric cohort. However, shorter LOS and lower costs associated with early decompression continue to support its uniform implementation after traumatic SCI.

Abstract
Traumatic spinal cord injury (TSCI) is frequent. Timely diagnosis and treatment have reduced the mortality, but the long-term recovery of neurologic functions remains ominous. After TSCI, tissue bleeding, edema, and adhesions lead to an increase in the intraspinal pressure, further causing the pathophysiologic processes of ischemia and hypoxia and eventually accelerating the cascade of secondary spinal cord injury. Timely surgery with appropriate decompression strategies can reduce that secondary injury. However, disagreement about the safety and effectiveness of decompression surgery and the timing of surgery still exists. The level and severity of spinal cord injury do have an impact on the timing of surgery; therefore, TSCI subpopulations may benefit from early surgery. Early surgery perhaps has little effect on recovery from complete TSCI but might be of benefit in patients with incomplete injury. Early decompression should be considered in patients with incomplete cervical TSCI. Patient age should not be used as an exclusion criterion for early surgery. The best time point for early surgery is although influenced by the shortest duration to thoroughly examine the patient's condition and stabilize the patient's state. After the patient's condition is fully evaluated, we can perform the surgical modality of emergency myelotomy and decompression. Therefore, a number of conditions should be considered, such as standardized decompression methods, indications and operation timing to ensure the effectiveness and safety of early surgical intervention, and promotion of the functional recovery of residual nerve tissue.

Abstract
The drawbacks of stem cell (SC) therapies have led to investigations of SC conditioned medium (CM) instead of SC transplantation in the repair of spinal cord injury (SCI). However, the effectiveness of CM in comparison with cell transplantation in SCI models remain an open and intriguing question. The focus of this review was to survey existing publications addressing this comparison. The review included articles from electronic databases Medline, Embase, Scopus, and Web of Science that included comparisons of the effects of CM versus SC transplantation and versus controls on locomotion after SCI. The search yielded 5 studies and 6 experiments. The results indicated that there was insufficient evidence to conclude that treatment with CM and source cells were equally effective (SMD = 0.12; 95% CI = -0.36 to 0.59; p = 0.07). Regarding investigations of separate effects of SCs versus CM, there currently is limited evidence on efficacy in SCI models. This highlights a notable concern affecting this field. Thus, we identified critical knowledge gaps concerning comparisons of the efficacy of therapeutic application of SC and their derived CM on functional recovery following SCI.

Abstract
Cervical spinal cord injury (SCI) usually results in severe, long-term disability. Early therapeutic hypothermia (33-34°C) has been used to improve outcomes in preclinical studies, but previous clinical studies have commenced cooling after arrival at hospital. The objective of the study is to determine the feasibility and safety of early therapeutic hypothermia initiated by paramedics and maintained for up to 24 hours in hospital in patients with SCI. This is a pilot clinical study. The study was undertaken at Ambulance Victoria and The Alfred Hospital, Victoria, Australia. A total of 17 consecutive patients with suspected acute traumatic cervical SCI were enrolled. Patients with suspected cervical SCI were administered a bolus (up to 20 mL/kg) intravenous (IV) cold (4°C) normal saline in the prehospital phase of care. After hospital admission and spinal imaging, further cooling used IV catheter temperature control or surface cooling. Major complications and long-term outcomes were compared with historical controls admitted to the same center before the study. A decrease in core temperature of 1.1°C was achieved during prehospital care and the target temperature was achieved in 6 hours with mechanical temperature management devices in the hospital. There were no major safety concerns. Patients with motor complete SCI who underwent early decompressive surgery had a favorable rate of partial spinal cord recovery compared with historical controls. Therapeutic hypothermia induced using bolus, large-volume, ice-cold saline prehospital and maintained for 24 hours using mechanical devices appears to be feasible and safe in patients with SCI. Larger trials need to be undertaken to determine whether prehospital cooling combined with early decompressive surgery improves outcomes in patients with complete cervical SCI.

Abstract
Spinal cord injury (SCI) remains an important public health problem which often causes permanent loss of muscle strength, sensation, and function below the site of the injury, generating physical, psychological, and social impacts throughout the lives of the affected individuals, since there are no effective treatments available. The use of stem cells has been investigated as a therapeutic approach for the treatment of SCI. Although a significant number of studies have been conducted in pre-clinical and clinical settings, so far there is no established cell therapy for the treatment of SCI. One aspect that makes it difficult to evaluate the efficacy is the heterogeneity of experimental designs in the clinical trials that have been published. Cell transplantation methods vary widely among the trials, and there are still no standardized protocols or recommendations for the therapeutic use of stem cells in SCI. Among the different cell types, mesenchymal stem/stromal cells (MSCs) are the most frequently tested in clinical trials for SCI treatment. This study reviews the clinical applications of MSCs for SCI, focusing on the critical analysis of 17 clinical trials published thus far, with emphasis on their design and quality. Moreover, it highlights the need for more evidence-based studies designed as randomized controlled trials and potential challenges to be addressed in context of stem cell therapies for SCI.

Abstract
There has been a shift in the management of the polytrauma patients from early total care to damage control orthopaedics (DCO), whereby patients with borderline hemodynamic stability may be temporized with the use of external fixators, traction, or splinting with delayed osteosynthesis of fractures. Recently, there has been an increasing trend toward a middle ground approach of Early Appropriate Care for polytrauma patients. The concepts of DCO for the spine are less clear, and the management of trauma patients with combined pelvic ring and spinal fractures or patients with noncontiguous spinal injuries present unique challenges to the surgeon in prioritization of patient needs. This review outlines the concept of DCO and Early Appropriate Care in the spine, prioritizing patient needs from the emergency department to the operating room. Concepts include the timing of surgery, minimally invasive versus open techniques, and the prioritization of spinal injuries in the setting of other orthopaedic and nonorthopaedic injuries. Contiguous and noncontiguous spinal injuries are considered in construct planning, and the principles are discussed.
