Abstract
PURPOSE This study compared the recovery of motor function and the safety of early and delayed surgical intervention in patients with central cord syndrome (CCS). METHODS PubMed, Embase, Cochrane Library, and Web of Science were employed to retrieve the targeted studies published from inception to February 19, 2023. Comparative studies of early versus delayed surgical decompression in CCS based on American Spinal Injury Association motor score (AMS) recovery, complication rates, and mortality were selected. The statistical analyses were performed using STATA 16.0 and RevMan 5.4. RESULTS Our meta-analysis included 13 studies comprising 8424 patients. Results revealed that early surgery improved AMS scores significantly compared with delayed surgery, with an increase in MDs by 7.22 points (95% CI 1.98-12.45; P = 0.007). Additionally, early surgery reduced the complication rates than delayed surgery (OR 0.53, 95% CI 0.42-0.67, P < 0.00001). However, no significant difference was observed in mortality between the two groups (OR 0.97; 95% CI 0.75-1.26; P = 0.84). CONCLUSIONS Early surgical decompression for CCS can improve motor function and reduce the incidence of complications without affecting the mortality rate in patients. Future research should focus on investigating and analyzing the optimal window period for early CCS surgery. Additionally, the timing of surgery should be determined based on the patient's condition and available medical resources.

Abstract
Acute traumatic spinal cord injury (tSCI) is a devastating occurrence that significantly contributes to global morbidity and mortality. Surgical decompression with stabilization is the most effective way to minimize the damaging sequelae that follow acute tSCI. In recent years, strong evidence has emerged that supports the rationale that early surgical intervention, within 24 h following the initial injury, is associated with a better prognosis and functional outcomes. In this review, we have summarized the evidence and elaborated on the nuances of this concept. Additionally, we have reviewed further concepts that stem from "time is spine," including earlier cutoffs less than 24 h and the challenging entity of central cord syndrome, as well as the emerging concept of adequate surgical decompression. Lastly, we identify barriers to early surgical care for acute tSCI, a key aspect of spine care that needs to be globally addressed via research and policy on an urgent basis.

Abstract
Importance The optimal clinical management of central cord syndrome (CCS) remains unclear; yet this is becoming an increasingly relevant public health problem in the face of an aging population. Objective To provide a head-to-head comparison of the neurologic and functional outcomes of early (<24 hours) vs late (≥24 hours) surgical decompression for CCS. Design, Setting, and Participants Patients who underwent surgery for CCS (lower extremity motor score [LEMS] - upper extremity motor score [UEMS] ≥ 5) were included in this propensity score-matched cohort study. Data were collected from December 1991 to March 2017, and the analysis was performed from March 2020 to January 2021. This study identified patients with CCS from 3 international multicenter studies with data on the timing of surgical decompression in spinal cord injury. Participants were included if they had a documented baseline neurologic examination performed within 14 days of injury. Participants were eligible if they underwent surgical decompression for CCS. Exposures Early surgery was compared with late surgery. Main Outcomes and Measures Propensity scores were calculated as the probability of undergoing early compared with late surgery using the logit method and adjusting for relevant confounders. Propensity score matching was performed in a 1:1 ratio by an optimal-matching technique. The primary end point was motor recovery (UEMS, LEMS, American Spinal Injury Association [ASIA] motor score [AMS]) at 1 year. Secondary end points were Functional Independence Measure (FIM) motor score and complete independence in each FIM motor domain at 1 year. Results The final study cohort consisted of 186 patients with CCS. The early-surgery group included 93 patients (mean [SD] age, 47.8 [16.8] years; 66 male [71.0%]), and the late-surgery group included 93 patients (mean [SD] age, 48.0 [15.5] years; 75 male [80.6%]). Early surgical decompression resulted in significantly improved recovery in upper limb (mean difference [MD], 2.3; 95% CI, 0-4.5; P = .047), but not lower limb (MD, 1.1; 95% CI, -0.8 to 3.0; P = .30), motor function. In an a priori-planned subgroup analysis, outcomes were comparable with early or late decompressive surgery in patients with ASIA Impairment Scale (AIS) grade D injury. However, in patients with AIS grade C injury, early surgery resulted in significantly greater recovery in overall motor score (MD, 9.5; 95% CI, 0.5-18.4; P = .04), owing to gains in both upper and lower limb motor function. Conclusions and Relevance This cohort study found early surgical decompression to be associated with improved recovery in upper limb motor function at 1 year in patients with CCS. Treatment paradigms for CCS should be redefined to encompass early surgical decompression as a neuroprotective therapy.

Abstract
The therapeutic significance of timing of decompression in acute traumatic central cord syndrome (ATCCS) caused by spinal stenosis remains unsettled. We retrospectively examined a homogenous cohort of patients with ATCCS and magnetic resonance imaging (MRI) evidence of post-treatment spinal cord decompression to determine whether timing of decompression played a significant role in American Spinal Injury Association (ASIA) motor score (AMS) 6 months following trauma. We used the t test, analysis of variance, Pearson correlation coefficient, and multiple regression for statistical analysis. During a 19-year period, 101 patients with ATCCS, admission ASIA Impairment Scale (AIS) grades C and D, and an admission AMS of ≤95 were surgically decompressed. Twenty-four of 101 patients had an AIS grade C injury. Eighty-two patients were males, the mean age of patients was 57.9 years, and 69 patients had had a fall. AMS at admission was 68.3 (standard deviation [SD] 23.4); upper extremities (UE) 28.6 (SD 14.7), and lower extremities (LE) 41.0 (SD 12.7). AMS at the latest follow-up was 93.1 (SD 12.8), UE 45.4 (SD 7.6), and LE 47.9 (SD 6.6). Mean number of stenotic segments was 2.8, mean canal compromise was 38.6% (SD 8.7%), and mean intramedullary lesion length (IMLL) was 23 mm (SD 11). Thirty-six of 101 patients had decompression within 24 h, 38 patients had decompression between 25 and 72 h, and 27 patients had decompression >72 h after injury. Demographics, etiology, AMS, AIS grade, morphometry, lesion length, surgical technique, steroid protocol, and follow-up AMS were not statistically different between groups treated at different times. We analyzed the effect size of timing of decompression categorically and in a continuous fashion. There was no significant effect of the timing of decompression on follow-up AMS. Only AMS at admission determined AMS at follow-up (coefficient = 0.31; 95% confidence interval [CI]:0.21; p = 0.001). We conclude that timing of decompression in ATCCS caused by spinal stenosis has little bearing on ultimate AMS at follow-up.

Abstract
STUDY DESIGN Narrative review. OBJECTIVE There is a strong biological rationale to perform early decompression after traumatic spinal cord injury (SCI). With an enlarging clinical evidence base, most spine surgeons internationally now favor early decompression for the majority of SCI patients; however, a number of pertinent questions remain surrounding this therapy. METHODS A narrative review evaluating the status of early surgery for SCI. In particular, we addressed the following questions: (1) Which patients stand to benefit most from early surgery? 2) What is the most appropriate time threshold defining early surgery? RESULTS Although heterogeneity exists, the evidence generally seems to support early surgery. While the best evidence exists for cervical SCI, there is insufficient data to support a differential effect for early surgery depending on neurological level or injury severity. When comparing thresholds to define early versus late surgery-including a later threshold (48-72 hours), an earlier threshold (24 hours), and an ultra-early threshold (8-12 hours)-the 2 earlier time points seem to be associated with the greatest potential for improved outcomes. However, existing prehospital and hospital logistics pose barriers to early surgery in a significant proportion of patients. An overview of recommendations from the recent AOSpine guidelines is provided. CONCLUSION In spite of increasing acceptance of early surgery post SCI, further research is needed to (1) identify subgroups of patients who stand to derive particular benefit-in particular to develop more evidence-based approaches for central cord syndrome and (2) investigate the efficacy and feasibility of ultra-early surgery targeting more aggressive timelines.

Abstract
Decompression is the major therapeutic strategy for acute spinal cord injury, but there is some debate about the time window for decompression following spinal cord injury. An important goal and challenge in the treatment of spinal cord injury is inhibiting or reversing secondary injury. Governor Vessel electroacupuncture can improve symptoms of spinal cord injury by inhibiting cell apoptosis and improving the microenvironment of the injured spinal cord. In this study, Governor Vessel electroacupuncture combined with decompression at different time points was used to treat acute spinal cord injury. The rat models were established by inserting a balloon catheter into the atlanto-occipital space. The upper cervical spinal cord was compressed for 12 or 48 hours prior to decompression. Electroacupuncture was conducted at the acupoints Dazhui (GV14) and Baihui (GV 20) (2 Hz, 15 minutes) once a day for 14 consecutive days. Compared with decompression alone, hind limb motor function recovery was superior after decompression for 12 and 48 hours combined with electroacupuncture. However, the recovery of motor function was not significantly different at 14 days after treatment in rats receiving decompression for 12 hours. Platelet-activating factor levels and caspase-9 protein expression were significantly reduced in rats receiving electroacupuncture compared with decompression alone. These findings indicate that compared with decompression alone, Governor Vessel electroacupuncture combined with delayed decompression (48 hours) is more effective in the treatment of upper cervical spinal cord injury. Governor Vessel electroacupuncture combined with early decompression (12 hours) can accelerate the recovery of nerve movement in rats with upper cervical spinal cord injury. Nevertheless, further studies are necessary to confirm whether it is possible to obtain additional benefit compared with early decompression alone.

Abstract
BACKGROUND CONTEXT Emergent surgery for patients with a traumatic spinal cord injury (SCI) is seen as the gold standard in acute management. However, optimal treatment for those with the clinical diagnosis of central cord syndrome (CCS) is less clear, and classic definitions of CCS do not identify a unique population of patients. PURPOSE The study aimed to test the authors' hypothesis that spine stability can identify a unique group of patients with regard to demographics, management, and outcomes, which classic CCS definitions do not. STUDY DESIGN/SETTING This is a prospective observational study. PATIENT SAMPLE The sample included participants with cervical SCI included in a prospective Canadian registry. OUTCOME MEASURES The outcome measures were initial hospitalization length of stay, change in total motor score from admission to discharge, and in-hospital mortality. METHODS Patients with cervical SCI from a prospective Canadian SCI registry were grouped into stable and unstable spine cohorts. Bivariate analyses were used to identify differences in demographic, injury, management, and outcomes. Multivariate analysis was used to better understand the impact of spine stability on motor score improvement. No conflicts of interest were identified. RESULTS Compared with those with an unstable spine, patients with cervical SCI and a stable spine were older (58.8 vs. 44.1 years, p<.0001), more likely male (86.4% vs. 76.1%, p=.0059), and have more medical comorbidities. Patients with stable spine cervical SCI were more likely to have sustained their injury by a fall (67.4% vs. 34.9%, p<.0001), and have high cervical (C1-C4; 58.5% vs. 43.3%, p=.0009) and less severe neurologic injuries (ASIA Impairment Scale C or D; 81.3% vs. 47.5%, p<.0001). Those with stable spine injuries were less likely to have surgery (67.6% vs. 92.6%, p<.0001), had shorter in-hospital lengths of stay (median 84.0 vs. 100.5 days, p=.0062), and higher total motor score change (20.7 vs. 19.4 points, p=.0014). Multivariate modeling revealed that neurologic severity of injury and spine stability were significantly related to motor score improvement; patients with stable spine injuries had more motor score improvement. CONCLUSIONS We propose that classification of stable cervical SCI is more clinically relevant than classic CCS classification as this group was found to be unique with regard to demographics, neurologic injury, management, and outcome, whereas classic CCS classifications do not . This classification can be used to assess optimal management in patients where it is less clear if and when surgery should be performed.

Abstract
BACKGROUND Cervical spondylotic myelopathy (CSM) is a common disease of aging that leads to gait instability resulting from loss of leg sensory and motor functions. The results of surgical intervention have been studied using a variety of methods, but no test has been reported that objectively measures integrative leg motor sensory functions in CSM patients. OBJECTIVE To determine the feasibility of using a novel single leg squat (SLS) test to measure integrative motor sensory functions in patients with CSM before and after surgery. METHODS Fifteen patients with CSM were enrolled in this prospective study. Clinical data and scores from standard outcomes questionnaires were obtained before and after surgery. Patients also participated in experimental test protocols consisting of standard kinematic gait testing, the Purdue pegboard test, and the novel SLS test. RESULTS The SLS test protocol was well tolerated by CSM patients and generated objective performance data over short test periods. In patients who participated in postoperative testing, the group measures of mean SLS errors decreased following surgery. Gait velocity measures followed a similar pattern of group improvement postoperatively. Practical barriers to implementing this extensive battery of tests resulted in subject attrition over time. Compared with kinematic gait testing, the SLS protocol required less space and could be effectively implemented more efficiently. CONCLUSIONS The SLS test provides a practical means of obtaining objective measures of leg motor sensory functions in patients with CSM. Additional testing with a larger cohort of patients is required to use SLS data to rigorously examine group treatment effects.

Abstract
RATIONALE This report describes interdisciplinary rehabilitation for a 51-year-old male recovering from incomplete cervical spinal cord injury (SCI) and multiple comorbidities following an automobile accident. PATIENT CONCERNS The patient was admitted to a rehabilitation specialty hospital approximately 2 months post SCI and 2 separate surgical fusion procedures (C3-C6). DIAGNOSES Clinical presentation at the rehabilitation hospital included moderate to severe motor strength loss in both upper and lower extremities, a percutaneous endoscopic gastronomy tube (PEG), dysphagia, bowel/bladder incontinence, dependence on a mechanical lift and tilting wheelchair due to severe orthostatic hypotension, and pre-existing shoulder pain from bilateral joint degeneration. INTERVENTIONS The interdisciplinary team formally coordinated rehabilitative care from multiple disciplines. Internal medicine managed medications, determined PEG removal, monitored co-morbid conditions, and overall progress. Chiropractic care focused on alleviating shoulder and thoracic pain and improving spinal and extremity mobility. Physical therapy addressed upright tolerance, transfer, gait, and strength training. Occupational therapy focused on hand coordination and feeding/dressing activities. Psychology assisted with coping strategies. Nursing ensured medication adherence, nutrient intake, wound prevention, and incontinence management, whereas physiatry addressed abnormal muscle tone. OUTCOMES Eleven months post-admission the patient's progress allowed discharge to a long-term care facility. At this time he was without dysphagia or need for a PEG. Orthostatic hypotension and bilateral shoulder pain symptoms were also resolved while bowel/bladder incontinence and upper and lower extremity motor strength loss remained. He was largely independent in transferring from bed to wheelchair and in upper body dressing. Lower body dressing/bathing required maximal assistance. Gait with a 2-wheeled walker was possible up to 150 feet with verbal cues and occasional stabilizing assistance. LESSONS Several specialties functioning within an interdisciplinary team fulfilled complementary roles to support rehabilitation for a patient with SCI.

Abstract
BACKGROUND This study aimed to investigate the medical expenses and outcomes of central cord syndrome (CCS), comparing patients who received surgical and non-surgical management. METHODS Using a 14-year nationwide database in Taiwan, this study followed-up all patients of CCS at least 5 years. The incidence rates, medical expenses, permanently disabled spinal cord injury (SCI), and mortality rates were compared for patients who underwent surgery and those who were managed conservatively. All CCS patients were further stratified by the level of injury (C1-4 vs. C5-7) in the cost analysis. RESULTS A total of 1,753 patients with CCS were followed and the incidence of CCS was the highest among males aged between 60 and 70 years, at 42.4 per 1,000,000 person-years. The total medical expenses were higher in the surgery than the non-surgery group (46,586.9 vs. 28,472.4, P<0.001) because of rehabilitation. The surgery group had a significantly lower rate of mortality (Odds Ratio= 0.34, P<0.05) and lower rates of permanently disabled SCI (OR= 4.92, all P<0.001). CONCLUSIONS The highest incidence rates of CCS were observed among males aged between 60 and 70 years. The expenses were higher but the mortality rate was lower for surgically managed patients. Further investigation is required to correlate the neurological outcomes to the management of CCS.

Abstract
STUDY DESIGN A systematic review of the literature for clinical and preclinical evidence related to timing of decompression following spinal cord injury (SCI). OBJECTIVE A review of the literature in search of consensus on what constitutes the ideal time frame for surgical management of SCI. SUMMARY OF BACKGROUND DATA Optimal timing for surgical management of SCI remains poorly defined. Despite multiple preclinical and clinical studies, there is still lack of consensus on the optimal time for surgery in SCI. METHODS We systematically reviewed the literature for clinical and preclinical evidence related to timing of decompression following SCI. For clinical studies, our review included papers published in English after January 1, 1990. For preclinical studies, we limited our review to papers published after January 2001. The OVID-Medline and Web of Science databases were reviewed for preclinical studies, and the OVID-Medline, Cochrane, and Embase databases were reviewed for clinical studies. RESULTS A total of 8792 preclinical articles were identified. Of those, only 14 met our inclusion criteria and were included in the analysis. A total of 25,190 clinical articles were identified. Of those, only 30 studies met our inclusion criteria and were included for analysis. Clinical studies reported on a total of 5236 patients, of whom 1665 underwent early decompression and 3571 underwent late decompression. There was significant variability in the definition of early and late decompression in both clinical and preclinical studies. Preclinical data were in favor of early decompression. From a clinical standpoint, there was only level II evidence proving safety and feasibility of early decompression with no definite evidence of improved outcome for any of the two groups. CONCLUSION There is growing evidence in favor of early decompression following SCI. Early decompression was proven to be clinically safe and feasible, but there is still no definite proof that early decompression leads to improved outcomes. LEVEL OF EVIDENCE 5.

Abstract
OBJECT
The optimal mean arterial pressure (MAP) for spinal cord perfusion after trauma remains unclear. Although there are published data on MAP goals after spinal cord injury (SCI), the specific blood pressure management for acute traumatic central cord syndrome (ATCCS) and the implications of these interventions have yet to be elucidated. Additionally, the complications of specific vasopressors have not been fully explored in this injury condition.
METHODS
The present study is a retrospective cohort analysis of 34 patients with ATCCS who received any vasopressor to maintain blood pressure above predetermined MAP goals at a single Level 1 trauma center. The collected variables were American Spinal Injury Association (ASIA) grades at admission and discharge, administered vasopressor and associated complications, other interventions and complications, and timing of surgery. The relationship between the 2 most common vasopressors—dopamine and phenylephrine—and complications within the cohort as a whole were explored, and again after stratification by age.
RESULTS
The mean age of the ATCCS patients was 62 years. Dopamine was the most commonly used primary vasopressor (91% of patients), followed by phenylephrine (65%). Vasopressors were administered to maintain MAP goals fora mean of 101 hours. Neurological status improved by a median of 1 ASIA grade in all patients, regardless of the choice of vasopressor. Sixty-four percent of surgical patients underwent decompression within 24 hours. There was no observed relationship between the timing of surgical intervention and the complication rate. Cardiogenic complications associated with vasopressor usage were notable in 68% of patients who received dopamine and 46% of patients who received phenylephrine. These differences were not statistically significant (OR with dopamine 2.50 [95% CI 0.82–7.78], p = 0.105). However, in the subgroup of patients > 55 years, dopamine produced statistically significant increases in the complication rates when compared with phenylephrine (83% vs 50% for dopamine and phenylephrine, respectively; OR with dopamine 5.0 [95% CI 0.99–25.34], p = 0.044).
CONCLUSIONS
Vasopressor usage in ATCCS patients is associated with complication rates that are similar to the reported literature for SCI. Dopamine was associated with a higher risk of complications in patients > 55 years. Given the increased incidence of ATCCS in older populations, determination of MAP goals and vasopressor administration should be carefully considered in these patients. While a randomized control trial on this topic may not be practical, a multiinstitutional prospective study for SCI that includes ATCCS patients as a subpopulation would be useful for examining MAP goals in this population.

Abstract
STUDY DESIGN A retrospective study of surgically treated patients with cervical spinal cord injury (SCI) from the National Trauma Data Bank Research Data Set. OBJECTIVE To determine how time to surgery differs between SCI subtypes, where delays before surgery occur, and what factors are associated with delays. SUMMARY OF BACKGROUND DATA Studies have shown that patients with cervical SCI undergoing surgery within 24 hours after injury have superior neurological outcomes to patients undergoing later surgery, with most evidence coming from the incomplete SCI subpopulation. METHODS Surgically treated patients with cervical SCI from 2011 and 2012 were identified in National Trauma Data Bank Research Data Set and divided into subpopulations of complete, central, and other incomplete SCIs. Relationships between surgical timing and patient and injury characteristics were analyzed using multivariate regression. RESULTS A total of 2636 patients with cervical SCI were identified: 803 with complete SCI, 950 with incomplete SCI, and 883 with central SCI. The average time to surgery was 51.1 hours for patients with complete SCI, 55.3 hours for patients with incomplete SCI, and 83.1 hours for patients with central SCI. Only 44% of patients with SCI underwent surgery within the first 24 hours after injury, including only 49% of patients with incomplete SCI.The vast majority of time between injury and surgery was after admission, rather than in the emergency department or in the field. Upper cervical SCIs and greater Charlson Comorbidity Index were associated with later surgery in all 3 SCI subpopulations. CONCLUSION The majority of patients with SCI do not undergo surgery within the first 24 hours after injury, and the majority of delays occur after inpatient admission. Factors associated with these delays highlight areas of focus for expediting care in these patient populations. LEVEL OF EVIDENCE 4.
