Utilization of Augmented Reality Head-Mounted Display for the Surgical Management of Thoracolumbar Spinal Trauma.

Background and Objectives: Augmented reality head-mounted display (AR-HMD) is a novel technology that provides surgeons with a real-time CT-guided 3-dimensional recapitulation of a patient's spinal anatomy. In this case series, we explore the use of AR-HMD alongside more traditional robotic assistance in surgical spine trauma cases to determine their effect on operative costs and perioperative outcomes. Materials and Methods: We retrospectively reviewed trauma patients who underwent pedicle screw placement surgery guided by AR-HMD or robotic-assisted platforms at an academic tertiary care center between 1 January 2021 and 31 December 2022. Outcome distributions were compared using the Mann-Whitney U test. Results: The AR cohort (n = 9) had a mean age of 66 years, BMI of 29.4 kg/m2, Charlson Comorbidity Index (CCI) of 4.1, and Surgical Invasiveness Index (SII) of 8.8. In total, 77 pedicle screws were placed in this cohort. Intra-operatively, there was a mean blood loss of 378 mL, 0.78 units transfused, 398 min spent in the operating room, and a 20-day LOS. The robotic cohort (n = 13) had a mean age of 56 years, BMI of 27.1 kg/m2, CCI of 3.8, and SII of 14.2. In total, 128 pedicle screws were placed in this cohort. Intra-operatively, there was a mean blood loss of 432 mL, 0.46 units transfused units used, 331 min spent in the operating room, and a 10.4-day LOS. No significant difference was found between the two cohorts in any outcome metrics. Conclusions: Although the need to address urgent spinal conditions poses a significant challenge to the implementation of innovative technologies in spine surgery, this study represents an initial effort to show that AR-HMD can yield comparable outcomes to traditional robotic surgical techniques. Moreover, it highlights the potential for AR-HMD to be readily integrated into Level 1 trauma centers without requiring extensive modifications or adjustments.

Assessing The Effectiveness and Complications of Lateral Mass Screw Fixation in Cervical Spine Trauma: A Clinical Review

Assessing The Effectiveness and Complications of Lateral Mass Screw Fixation in Cervical Spine Trauma: A Clinical Review

Interobserver Reliability in the Classification of Thoracolumbar Fractures Using the AO Spine TL Injury Classification System Among 22 Clinical Experts in Spine Trauma Care.

Reliability study utilizing 183 injury CT scans by 22 spine trauma experts with assessment of radiographic features, classification of injuries and treatment recommendations. To assess the reliability of the AOSpine TL Injury Classification System (TLICS) including the categories within the classification and the M1 modifier. Kappa and Intraclass correlation coefficients were produced. Associations of various imaging characteristics (comminution, PLC status) and treatment recommendations were analyzed through regression analysis. Multivariable logistic regression modeling was used for making predictive algorithms. Reliability of the AO Spine TLICS at differentiating A3 and A4 injuries (N = 71) (K = .466; 95% CI .458 - .474; P < .001) demonstrated moderate agreement. Similarly, the average intraclass correlation coefficient (ICC) amongst A3 and A4 injuries was excellent (ICC = .934; 95% CI .919 - .947; P < .001) and the ICC between individual measures was moderate (ICC = .403; 95% CI .351 - .461; P < .001). The overall agreement on the utilization of the M1 modifier amongst A3 and A4 injuries was fair (K = .161; 95% CI .151 - .171; P < .001). The ICC for PLC status in A3 and A4 injuries averaged across all measures was excellent (ICC = .936; 95% CI .922 - .949; P < .001). The M1 modifier suggests respondents are nearly 40% more confident that the PLC is injured amongst all injuries. The M1 modifier was employed at a higher frequency as injuries were classified higher in the classification system. The reliability of surgeons differentiating between A3 and A4 injuries in the AOSpine TLICS is substantial and the utilization of the M1 modifier occurs more frequently with higher grades in the system.

TomoRay: Generating Synthetic Computed Tomography of the Spine From Biplanar Radiographs.

Computed tomography (CT) imaging is a cornerstone in the assessment of patients with spinal trauma and in the planning of spinal interventions. However, CT studies are associated with logistical problems, acquisition costs, and radiation exposure. In this proof-of-concept study, the feasibility of generating synthetic spinal CT images using biplanar radiographs was explored. This could expand the potential applications of x-ray machines pre-, post-, and even intraoperatively. A cohort of 209 patients who underwent spinal CT imaging from the VerSe2020 dataset was used to train the algorithm. The model was subsequently evaluated using an internal and external validation set containing 55 from the VerSe2020 dataset and a subset of 56 images from the CTSpine1K dataset, respectively. Digitally reconstructed radiographs served as input for training and evaluation of the 2-dimensional (2D)-to-3-dimentional (3D) generative adversarial model. Model performance was assessed using peak signal to noise ratio (PSNR), structural similarity index (SSIM), and cosine similarity (CS). At external validation, the developed model achieved a PSNR of 21.139 ± 1.018 dB (mean ± standard deviation). The SSIM and CS amounted to 0.947 ± 0.010 and 0.671 ± 0.691, respectively. Generating an artificial 3D output from 2D imaging is challenging, especially for spinal imaging, where x-rays are known to deliver insufficient information frequently. Although the synthetic CT scans derived from our model do not perfectly match their ground truth CT, our proof-of-concept study warrants further exploration of the potential of this technology.

DWI of the Spine: A Review and Update

The utility of DWI in the spine has been established and continues to grow in clinical practice. DWI raises the MR imaging sensitivity of lesion detection and improves the conspicuity of many spinal pathologies. Applications include evaluation of spinal cord infarction, bone marrow lesions, infection, degenerative disease, trauma, osteoporosis, malignancy, and response to therapy. In this article, we provide a case-based review to illustrate and discuss these uses. We also highlight DWI acquisition techniques and challenges. We provide protocol optimization tips that help to overcome these challenges and permit incorporation of DWI into the workflow.Learning Objective: To emphasize the role of DWI in the spine and discuss technical tips and considerations for protocol optimization

Chronic Treatment with Serotonin Selective Reuptake Inhibitors Does Not Affect Regrowth of Serotonin Axons Following Amphetamine Injury in the Mouse Forebrain.

A current hypothesis to explain the limited recovery following brain and spinal cord trauma stems from the dogma that neurons in the mammalian central nervous system lack the ability to regenerate their axons after injury. Serotonin (5-HT) neurons in the adult brain are a notable exception in that they can slowly regrow their axons following chemical or mechanical lesions. This process of regrowth occurs without intervention over several months and results in anatomical recovery that approximates the preinjured state. During development, serotonin is a trophic factor, playing a role in both cell survival and axon growth. Additionally, some studies have shown that stroke patients treated after injury with serotonin selective reuptake inhibitors (SSRIs) appeared to have improved recovery. To test the hypothesis that serotonin can influence the regrowth of 5-HT axons, mice received a high dose of para-chloroamphetamine (PCA) to induce widespread retrograde degeneration of 5-HT axons. Then, after a short rest period to avoid any interaction with the acute injury phase, SSRIs were administered daily for 6 or 10 weeks. Using immunohistochemistry in 5-HT transporter-GFP BAC transgenic mice, we determined that while PCA led to a rapid initial decrease in total 5-HT axon length in the somatosensory cortex, visual cortex, or area CA1 of the hippocampus, treatment with either fluoxetine or sertraline (two different SSRIs) did not affect the recovery of axon length. These results suggest that chronic SSRI treatment does not affect the regrowth of 5-HT axons and argue against SSRIs as a potential therapy following brain injury.

Understanding Decision Making as It Influences Treatment in Thoracolumbar Burst Fractures Without Neurological Deficit: Conceptual Framework and Methodology.

This paper presents a description of a conceptual framework and methodology that is applicable to the manuscripts that comprise this focus issue. Our goal is to present a conceptual framework which is relied upon to better understand the processes through which surgeons make therapeutic decisions around how to treat thoracolumbar burst fractures (TL) fractures. We will describe the methodology used in the AO Spine TL A3/4 Study prospective observational study and how the radiographs collected for this study were utilized to study the relationships between various variables that factor into surgeon decision making. With 22 expert spine trauma surgeons analyzing the acute CT scans of 183 patients with TL fractures we were able to perform pairwise analyses, look at reliability and correlations between responses and develop frequency tables, and regression models to assess the relationships and interactions between variables. We also used machine learning to develop decision trees. This paper outlines the overall methodological elements that are common to the subsequent papers in this focus issue.

A Novel Radiological Scoring System for Anterior Longitudinal Ligament Injuries.

Cervical hyperextension injury is very frequent with anterior longitudinal ligament (ALL) injury, and the ligament damage has a remarkable effect on whether and what type of operation should be performed. This study aims to establish a new scoring system for the accurate diagnosis of ALL damage. The imaging data of the consecutive patients was measured and scored by four radiologists. Intraoperative exploration was performed by three surgeons. The crude and adjusted odds ratios (cOR and aOR) and receiver operating characteristic curve (ROC) were constructed to assess the diagnostic accuracy of the scoring system. A total of 255 patients with cervical spine trauma were included in this study. There was no statistical difference in the relationship between demographics and ALL injuries (P > 0.05). Thickness of prevertebral soft tissue (aOR = 11.922, P = 0.004), intervertebral disk angle (aOR = 13.21, P = 0.002), avulsion fracture of the anterior edge of the vertebral body (aOR = 13.844, P = 0.029), ALL disrupted in T1-weighted sequence (aOR = 18.349, P < 0.001), and high signal area in T2-weighted sequence (aOR = 20.898, P = 0.002) had significantly higher diagnostic accuracy. The scoring system's sensitivity and specificity were 94.0% and 88.1%, respectively, and the accuracy was 90.8%. The study established a new scoring system for ALL injuries based on the analysis of a series of clinical data and statistics. A total of five scoring items, a total score of 7 points, and an ALL injury may be diagnosed when the score is not less than 3 points. This scoring system enables an efficient and accurate diagnosis of all injuries.

The Influence of Comminution and Posterior Ligamentous Complex Integrity on Treatment Decision Making in Thoracolumbar Burst Fractures Without Neurologic Deficit?

A prospective study. to evaluate the impact of vertebral body comminution and Posterior Ligamentous Complex (PLC) integrity on the treatment recommendations of thoracolumbar fractures among an expert panel of 22 spine surgeons. A review of 183 prospectively collected thoracolumbar burst fracture computed tomography (CT) scans by an expert panel of 22 trauma spine surgeons to assess vertebral body comminution and PLC integrity. This study is a sub-study of a prospective observational study of thoracolumbar burst fractures (Spine TL A3/A4). Each expert was asked to grade the degree of comminution and certainty about the PLC disruption from 0 to 100, with 0 representing the intact vertebral body or intact PLC and 100 representing complete comminution or complete PLC disruption, respectively. ≥45% comminution had a 74% chance of having surgery recommended, while <25% comminution had an 86.3% chance of non-surgical treatment. A comminution from 25 to 45% had a 57% chance of non-surgical management. ≥55% PLC injury certainity had a 97% chance of having surgery, and ≥45-55% PLC injury certainty had a 65%. <20% PLC injury had a 64% chance of having non-operative treatment. A 20 to 45% PLC injury certainity had a 56% chance of non-surgical management. There was fair inter-rater agreement on the degree of comminution (ICC .57 [95% CI 0.52-.63]) and the PLC integrity (ICC .42 [95% CI 0.37-.48]). The study concludes that vetebral comminution and PLC integrity are major dterminant in decision making of thoracolumbar fractures without neurological deficit. However, more objective, reliable, and accurate methods of assessment of these variables are warranted.

Utility of brain imaging in pediatric patients with a suspected accidental spinal injury but no brain injury-related symptoms

PurposeImaging is the gold standard in diagnosing traumatic brain injury, but unnecessary scans should be avoided, especially in children and adolescents. Clinical decision-making rules often help to distinguish the patients who need imaging, but if spinal trauma is suspected, concomitant brain imaging is often conducted. Whether the co-occurrence of brain and spine injuries is high enough to justify head imaging in patients without symptoms suggesting brain injury is unknown.ObjectiveThis study aims to assess the diagnostic yield of brain MRI in pediatric patients with suspected or confirmed accidental spinal trauma but no potential brain injury symptoms.MethodsWe retrospectively reviewed the medical and imaging data of pediatric patients (under 18 years old) who have undergone concomitant MRI of the brain and spine because of acute spinal trauma in our emergency radiology department over a period of 8 years. We compared the brain MRI findings in patients with and without symptoms suggesting brain injury and contrasted spine and brain MRI findings.ResultsOf 179 patients (mean age 11.7 years, range 0–17), 137 had symptoms or clinical findings suggesting brain injury, and 42 did not. None of the patients without potential brain injury symptoms had traumatic findings in brain MRI. This finding also applied to patients with high-energy trauma (n = 47) and was unrelated to spinal MRI findings.ConclusionPediatric accidental trauma patients with suspected or confirmed spine trauma but no symptoms or clinical findings suggesting brain injury seem not to benefit from brain imaging.

Non-Neurogenic ‘Christmas Tree’ Urinary Bladder in A 30-Year-Old Man with Urethral Stricture: A Case Report

condition the urinary bladder appears elongated and pointed with a thickened, trabeculated wall likened to a Christmas tree. It is most commonly the result of neurogenic bladder from detrusor hyperreflexia which most commonly occurs after spinal trauma. Christmas tree bladder also may rarely be seen in cases of bladder neck obstruction of non- neurogenic cause. A 30-year-old male presented with two weeks history of leakage of urine par the perineum. There was prior history of urethral discharge, poor urinary stream, urine dribbling and dysuria. No history of genital trauma, urethral instrumentation or catheterization in past. Attempt at passage of urethral catheter failed. He subsequently had open supra pubic cystostomy. Ultrasonography shows multiple internal echoes in the urine with thickened irregular bladder wall. The upper urinary tract was normal. Combine RUG and VCUG demonstrate short segments strictures at the bulbar and membranous urethra. A track of contrast column was noted from the region of the bulbar stricture to the exterior consistent with urethro-cutaneous fistula. The urinary bladder appears large, elongated superiorly with irregular outline resembling ‘Christmas tree’ configuration.

Our experience with the surgical management of lower cervical spine fractures: fifty case series.

Trauma to the lower cervical spine is a serious lesion due to its neurological consequences which jeopardize the vital and functional prognosis. They constitute a public health problem due to their frequency and seriousness requiring rapid and adequate treatment. The aim of our study is to (1) describe the epidemiological, clinical, and radiological characteristics of lower cervical spine trauma patients; (2) support the therapeutic management of these patients and show our experience in surgery for lower cervical spine trauma; and (3) analyze the anatomical and functional results and discuss them with literature data. This is a retrospective descriptive study of 50 patients with lower cervical spine trauma treated surgically over a period of five years from January 1, 2016, to December 2020. The average age of our patients was 34.5 years, with a sex ratio of 1.7. The etiologies are dominated by accidents on public roads (58%). They show neurological disorders such as spinal cord damage in 30% of cases and root damage in 20% of cases. The radiological assessment revealed eight tear drops, ten comminuted fractures, 12 severe sprains, 12 biarticular dislocations, six uniarticular dislocations, and two herniated discs. Treatment was surgical in all patients with an anterolateral approach and anterior arthrodesis. The evolution was favourable in 21 patients and stationary in 29 patients. Our study concluded that dislocations and fracture dislocations were the predominant type of injury in cases of AVP. Tetraplegia was mainly observed with uni- and biarticular dislocations. The variation in consolidation time was not correlated with trauma-to-surgery time. Better neurological recovery was observed with mild initial neurological damage than with initially severe damage. The appearance of an adjacent syndrome is less frequent with monosegmental arthrodesis than with multisegmental arthrodesis. Cage arthrodesis was an alternative to iliac harvesting with similar results.

Is it true that treatment in patients with Subaxial Cervical Spine Injury Classification System (SLICS) 4 is the surgeon's choice?

The Subaxial Cervical Spine Injury Classification System (SLICS) is a commonly used algorithm for diagnosing and managing subaxial cervical spine trauma. A SLIC score 4 suggests either surgery or non-surgically treatment depending on the surgeon's experience and patient's conditions. Prognosis and treatment results were analyzed in patients with SLIC score 4. The patients with SLIC score 4 were retrospectively reviewed from 2012 to 2019. Forty-one patients were included and divided into two groups: non-surgically treated and surgically treated. Demographic data and radiographs were analyzed. Statistical analysis was performed to determine the difference between the two clinical groups. Twenty-two patients were non-surgically treated, and nineteen patients were surgically treated. There was no neurological deterioration in both groups. However, there was no statistically significant difference in the last follow-up AISA and Nurick grade (p> 0.05). There was no significant difference in the number of patients who showed improvement when comparing the initial and the last follow-up neurological status (p> 0.05). Regardless of the treatment method, the spinal cord injury patients with SLICS point 4 showed a relatively good prognosis. Patients with SLIC score 4 could be treated non-surgically or surgically based on the surgeon's experience and factors associated with the patient's acute health status and chronic comorbidities.

Cardiac risk stratification and adverse outcomes in surgically managed patients with isolated traumatic spine injuries

IntroductionAs the incidence of traumatic spine injuries has been steadily increasing, especially in the elderly, the ability to categorize patients based on their underlying risk for the adverse outcomes could be of great value in clinical decision making. This study aimed to investigate the association between the Revised Cardiac Risk Index (RCRI) and adverse outcomes in patients who have undergone surgery for traumatic spine injuries.MethodsAll adult patients (18 years or older) in the 2013–2019 TQIP database with isolated spine injuries resulting from blunt force trauma, who underwent spinal surgery, were eligible for inclusion in the study. The association between the RCRI and in-hospital mortality, cardiopulmonary complications, and failure-to-rescue (FTR) was determined using Poisson regression models with robust standard errors to adjust for potential confounding.ResultsA total of 39,391 patients were included for further analysis. In the regression model, an RCRI ≥ 3 was associated with a threefold risk of in-hospital mortality [adjusted IRR (95% CI): 3.19 (2.30–4.43), p < 0.001] and cardiopulmonary complications [adjusted IRR (95% CI): 3.27 (2.46–4.34), p < 0.001], as well as a fourfold risk of FTR [adjusted IRR (95% CI): 4.27 (2.59–7.02), p < 0.001], compared to RCRI 0. The risk of all adverse outcomes increased stepwise along with each RCRI score.ConclusionThe RCRI may be a useful tool for identifying patients with traumatic spine injuries who are at an increased risk of in-hospital mortality, cardiopulmonary complications, and failure-to-rescue after surgery.

Clinical Effectiveness of Minimally Invasive Surgery on Spinal Trauma.

Minimally invasive spinal trauma surgery includes percutaneous pedicle screw fixation and miniature open anterolateral retractor-based approaches, which can improve surgical outcomes by reducing blood loss, operative time, and postoperative pain. Therefore, this study aimed to evaluate the effect of minimally invasive surgery on pain scores, functional recovery, and postoperative complications in patients with spinal trauma. This retrospective study included 100 spinal trauma patients treated in Suzhou Hospital of Integrated Traditional Chinese and Western Medicine between May 2019 and May 2022. Patients who underwent traditional open surgery were included in the traditional group, and those who received percutaneous pedicle screw internal fixation combined with posterior minimally invasive small incision decompression were included in the research group, each comprising 50 patients. The effectiveness of these two surgical approaches was determined by assessing their outcome measures, including surgery-related indices, postoperative pain, spinal morphology, functional recovery, and postoperative complications. Minimally invasive surgery was associated with significantly shorter surgical wounds, length of hospital stay, operative time, and postoperative time-lapse before off-bed activity, and less intraoperative hemorrhage volume and postoperative drainage volume compared to open surgery (p < 0.001). Compared to open surgery, patients with minimally invasive surgery showed significantly lower visual analogue scale (VAS) scores at 3 days, 3 months, and 6 months after surgery and lower Oswestry dysfunction index (ODI) at 7 days and 3 months after surgery (p < 0.05). Furthermore, the difference in the spine morphology between the two arms did not achieve statistical significance (p > 0.05). Additionally, minimally invasive surgery resulted in a significantly lower incidence of postoperative complications than open surgery (p < 0.05). Minimally invasive surgery causes less surgical damage for patients with spinal trauma, improves surgery-related indexes, alleviates postoperative pain, and provides better morphological and functional recovery of the spine.

Investigating Factors Affecting Mortality Due to Spinal Cord Trauma in Patients Admitted to the Intensive Care Unit.

This study was conducted to investigate the factors affecting mortality due to spinal cord trauma in patients admitted to the intensive care unit (ICU). This study was conducted in a group of patients who were admitted to the ICU with a Traumatic Spinal Injuries (TSI) diagnosis. The researcher started sampling by assessing the documents of the patients hospitalized in the ICU, and the diagnosis of TSI was confirmed for them. Besides, utilizing a researcher-made checklist, factors affecting the mortality of patients were identified. The data were analyzed using the SPSS software version 16. P<0.05 was considered statistically significant. About 412 (64.2%) patients were men, about 213 (33.2%) of the patients had GCS between 3-8 grade. There were injuries in the pelvis area. Moreover, there was a significant relationship between GCS score status and the number of injury follow-ups in addition to TSI. Therefore, the mortality rate was higher in patients who had lower GCS (Odds ratio=2.32, p<0.001). There was also a significant relationship between the number of injuries and the mortality rate, and patients who had multiple traumas had a higher mortality rate. Besides, a significant relationship was observed between the complications caused by trauma, including cerebrovascular accident, cardiac arrest, acute respiratory distress syndrome (ARDS), pneumonia, and the mortality of patients hospitalized in the SICU (p<0.05). The patients' mortality was influenced by factors such as their level of consciousness, the number of traumas caused in the spinal cord, and the occurrence of comorbidities such as cerebrovascular accident, cardiac arrest, ARDS, and pneumonia. Therefore, it is necessary to take the essential measures to reduce these complications.

Emergency management of traumatic spinal cord injury: a systematic review

Globally, trauma is a prominent factor contributing to mortality and impairment. Hemorrhage accounts for up to 40% of fatalities resulting from traumatic injuries. Current approaches to improve mortality rates have prioritized the implementation of effective techniques for the early management of bleeding and the treatment of coagulation disorders. This is an updated systematic review of studies that examined the emergency care of traumatic spinal cord injury (SCI) from 2017 to 2023. A literature search was conducted using Google Scholar, Web of Science, Cochrane, and PubMed databases to find relevant research on our issue. The search terms used were &amp;quot;SCI, Spine trauma, Emergency, management, Traumatic cervical SCI&amp;quot; and were employed in different combinations. Furthermore, an assessment was conducted on original research that examines the emergency care of severe SCI. The inclusion criteria were based on full-text publications. Out of the 85 research that were collected, only nine satisfied the inclusion requirements. Out of the total number of studies, seven were conducted retrospectively, one was a case report, and another was a cross-sectional research. The research population consisted of around 159,982 individuals diagnosed with SCI. Respiratory ssues, septicemia, and cardiovascular complications were the leading causes of in-hospital mortality in those with complete acute SCI. Elderly people, physical injuries, paralysis of all four limbs, and reliance on mechanical breathing were all associated with greater death rates. The American Spinal Injury Association grade upon admission was the greatest predictor of morbidity and death. Road traffic accidents were the major cause of CI among Saudi men. Bomb blasts quickly followed falls, gaining second place. Road traffic accidents are the second most common cause of SCI among females, behind falls. Younger people who suffer spinal cord injuries frequently were found to have a better prognosis for recovery than older people.

Bone Substitute Options for Spine Fusion in Patients With Spine Trauma-Part II: The Role of rhBMP.

In Part II, we focus on an important aspect of spine fusion in patients with spine trauma: the pivotal role of recombinant human bone morphogenetic protein-2 (rhBMP-2). Despite the influx of diverse techniques facilitated by technological advancements in spinal surgery, spinal fusion surgery remains widely used globally. The persistent challenge of spinal pseudarthrosis has driven extensive efforts to achieve clinically favorable fusion outcomes, with particular emphasis on the evolution of bone graft substitutes. Part II of this review aims to build upon the foundation laid out in Part I by providing a comprehensive summary of commonly utilized bone graft substitutes for spinal fusion in patients with spinal trauma. Additionally, it will delve into the latest advancements and insights regarding the application of rhBMP-2, offering an updated perspective on its role in enhancing the success of spinal fusion procedures.

Is mechanism of injury associated with outcome in spinal trauma? An observational cohort study from Tanzania.

Traumatic spinal injury (TSI) is a disease of significant global health burden, particularly in low and middle-income countries where road traffic-related trauma is increasing. This study compared the demographics, injury patterns, and outcomes of TSI caused by road traffic accidents (RTAs) to non-traffic related TSI. A retrospective analysis was conducted using a neurotrauma registry from the Muhimbili Orthopaedic Institute (MOI) in Tanzania, a national referral center for spinal injuries. Patient sociodemographic characteristics, injury level, and severity were compared across mechanisms of injury. Neurological improvement, neurological deterioration, and mortality were compared between those sustaining TSI through an RTA versus non-RTA, using univariable and multivariable analyses. A total of 626 patients were included, of which 302 (48%) were RTA-related. The median age was 34 years, and 532 (85%) were male. RTAs had a lower male preponderance compared to non-RTA causes (238/302, 79% vs. 294/324, 91%, p<0.001) and a higher proportion of cervical injuries (144/302, 48% vs. 122/324, 38%, p<0.001). No significant differences between RTA and non-RTA mechanisms were found in injury severity, time to admission, length of hospital stay, surgical intervention, neurological outcomes, or in-hospital mortality. Improved neurological outcomes were associated with incomplete injuries (AIS B-D), while higher mortality rates were linked to cervical injuries and complete (AIS A) injuries. Our study in urban Tanzania finds no significant differences in outcomes between spinal injuries from road traffic accidents (RTAs) and non-RTA causes, suggesting the need for equitable resource allocation in spine trauma programs. Highlighting the critical link between cervical injuries and increased mortality, our findings call for targeted interventions across all causes of traumatic spinal injuries (TSI). We advocate for a comprehensive trauma care system that merges efficient pre-hospital care, specialized treatment, and prevention measures, aiming to enhance outcomes and ensure equity in trauma care in low- and middle-income countries.

Reconstruction of Multiple Location Bedsores

Fillet flaps and autografts are reserved as a last resort option of reconstructive surgery and are indicated in extensive, recurrent, or bilateral defects especially caused by spinal trauma, commonly as a result of pressure sores trauma or tumour disease. No early and late-term complications were seen post-operatively that led to improvement in quality of life of the patient. The patient is able to perform a lot of daily routines – replacement of a long urinary catheter, getting dressed, is aware of the health condition, and behaves responsibly. An auto-flap creation with the right leg exarticulation was a reconstructive manipulation to maximise physiology and integrity of the spinal trauma patient. In the evaluated clinical case, fillet flaps and autografts were reserved as a last resort option for reconstructive surgery and were indicated because of extensive, recurrent, bilateral pressure sores caused by immobility. Keywords: reconstruction; bedsores.
