Surgical and Medical Management of Pediatric Spine Trauma.

Pediatric spine trauma is rare but presents unique challenges to clinical management. Special considerations include but are not limited to the need to minimize ionizing radiation in this patient population, anatomic immaturity, physiologic variants, and injuries seen only in the pediatric population. Here we review the epidemiology of pediatric spine trauma, presentation, diagnosis, and treatment of the most common injuries and discuss specific medical and surgical strategies for treatment.

Hybrid-3D robotic suite in spine and trauma surgery - experiences in 210 patients.

BACKGROUND: In modern Hybrid ORs, the synergies of navigation and robotics are assumed to contribute to the optimisation of the treatment in trauma, orthopaedic and spine surgery. Despite promising evidence in the area of navigation and robotics, previous publications have not definitively proven the potential benefits. Therefore, the aim of this retrospective study was to evaluate the potential benefit and clinical outcome of patients treated in a fully equipped 3D-Navigation Hybrid OR. METHODS: Prospective data was collected (March 2022- March 2024) after implementation of a fully equipped 3D-Navigation Hybrid OR ("Robotic Suite") in the authors level 1 trauma centre. The OR includes a navigation unit, a cone beam CT (CBCT), a robotic arm and mixed reality glasses. Surgeries with different indications of the spine, the pelvis (pelvic ring and acetabulum) and the extremities were performed. Spinal and non-spinal screws were inserted. The collected data was analysed retrospectively. Pedicle screw accuracy was graded according to the Gertzbein and Robbins (GR) classification. RESULTS: A total of n = 210 patients (118 m:92f) were treated in our 3D-Navigation Hybrid OR, with 1171 screws inserted. Among these patients, 23 patients (11.0%) arrived at the hospital via the trauma room with an average Injury Severity Score (ISS) of 25.7. There were 1035 (88.4%) spinal screws inserted at an accuracy rate of 98.7% (CI95%: 98.1-99.4%; 911 GR-A & 111 GR-B screws). The number of non-spinal screws were 136 (11.6%) with an accuracy rate of 99.3% (CI95%: 97.8-100.0%; 135 correctly placed screws). This resulted in an overall accuracy rate of 98.8% (CI95%: 98.2-99.4%). The robotic arm was used in 152 cases (72.4%), minimally invasive surgery (MIS) was performed in 139 cases (66.2%) and wound infection occurred in 4 cases (1,9%). Overall, no revisions were needed. CONCLUSION: By extending the scope of application, this study showed that interventions in a fully equipped 3D-Navigation Hybrid OR can be successfully performed not only on the spine, but also on the pelvis and extremities. In trauma, orthopaedics and spinal surgery, navigation and robotics can be used to perform operations with a high degree of precision, increased safety, reduced radiation exposure for the OR-team and a very low complication rate.

Clinical Effectiveness of Minimally Invasive Surgery on Spinal Trauma.

AIM: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

[Cervical Spine Injuries]. / Verletzungen der oberen Halswirbelsäule.

Around a third of all cervical spine injuries occur in the upper cervical spine in the area between the occiput and the second cervical vertebra. The latter being the most common location of the injury with around 70%. But also atlas fractures, occipital condyle fractures, traumatic spondylolisthesis of C2, atypical fractures in the corpus area as well as atlantooccipital and atlantoaxial ligamentous lesions should be mentioned in connection with injuries in this area. In many cases, conservative therapy regimen is possible. In unstable or displaced injuries, however, surgical intervention is required, with various surgical procedures being used. The frequency, diagnostics, classification, and standard therapy of the individual entities are presented in detail in this continuing medical education article.

Functional outcomes in unstable complete subaxial cervical spinal injuries with respiratory paralysis and/or hemodynamic instability.

INTRODUCTION: Subaxial cervical spine injuries (SCSI) can lead to disastrous consequences such as quadriplegia, with/without respiratory paralysis (RP) and hemodynamic instability (HDI). Till date, there is no literature available for reporting outcomes of SCSI patients specifically pertaining to those presenting with RP/HDI and ours is the first study to document the same. METHODS: Retrospective 6-year study from a tertiary trauma centre database including patients >/= 18 years of operated SCSI. Only patients with ASIA A grade with admission RP/HDI and unstable injuries (fractures, subluxations) were included. Patients with ASIA grade B and above, patients with non-osseous injuries (such as disc herniation, central cord syndrome etc.) were excluded. RESULTS: 24 cases were analysed. C5 and C6 levels were the commonest. Vertebral listhesis/subluxation was the predominant radiological finding. The mean age was 47.4 years (22-79 years) and all, except one were males. Fall from height and road traffic accident (RTA) were the most common mechanisms of injury. The most common surgery was anterior discectomy and fusion followed by corpectomy. The overall mortality rate was 22/24 (92)%. Cord edema and hemorrhage had significant association with survival. None of the grade A survivors with HDI/RP showed improvement. The mean FU duration was 18.5 months (range, 16.5-20.5 months). CONCLUSIONS: Subaxial ASIA A cervical spine injuries with pre-operative RP/HDI is an indicator for non-improvement. This is the first study documenting outcome in such patients. The mortality rate in these patients is very high and is an extremely poor prognostic factor for recovery. Hence, surgery in such patients need to be decided judiciously, especially in developing countries that has a significant financial impact on the family members.

Safety of anterior cervical corpectomy and fusion (ACCF) for the treatment of subaxial cervical spine injuries, a single center comparative matched analysis.

INTRODUCTION: Anterior Cervical Discectomy and Fusion (ACDF) and Anterior Cervical Corpectomy and Fusion (ACCF) are both common surgical procedures in the management of pathologies of the subaxial cervical spine. While recent reviews have demonstrated ACCF to provide better decompression results compared to ACDF, the procedure has been associated with increased surgical risks. Nonetheless, the use of ACCF in a traumatic context has been poorly described. The aim of this study was to assess the safety of ACCF as compared to the more commonly performed ACDF. METHODS: All patients undergoing ACCF or ACDF for subaxial cervical spine injuries spanning over 2 disc-spaces and 3 vertebral-levels, between 2006 and 2018, at the study center, were eligible for inclusion. Patients were matched based on age and preoperative ASIA score. RESULTS: After matching, 60 patients were included in the matched analysis, where 30 underwent ACDF and ACCF, respectively. Vertebral body injury was significantly more common in the ACCF group (p = 0.002), while traumatic disc rupture was more frequent in the ACDF group (p = 0.032). There were no statistically significant differences in the rates of surgical complications, including implant failure, wound infection, dysphagia, CSF leakage between the groups (p ≥ 0.05). The rates of revision surgeries (p > 0.999), mortality (p = 0.222), and long-term ASIA scores (p = 0.081) were also similar. CONCLUSION: Results of both unmatched and matched analyses indicate that ACCF has comparable outcomes and no additional risks compared to ACDF. It is thus a safe approach and should be considered for patients with extensive anterior column injury.

[Vertebral artery dissection during traumatic injury of the cervical spine, two case reports]. / Nyaki gerinc traumás sérülése során jelentkezo arteria vertebralis dissectio, két esetbemutatás.

If severe cervical spinal cord injury or severe cervical vertebral fracture, subluxation or luxation is confirmed, 20-40% of the cases have vertebral artery dissection or occlusion. These can be asymptomatic, but can cause additional neurological damage in addition to cervical myelon and cervical nerve root symptoms. Vertebral artery dissection can be caused by direct injuries, stab wounds or gunshot wounds. Indirect vertebral artery dissection can occur at the same time as subluxation, luxation, or complex fractures of the cervical vertebra. CTA is the examination procedure of choice. In many cases, digital subtaction angiography examination and, if necessary, neurointerventional treatment must precede open neurosurgery. In our report, in the first patient, complete luxation of the C.VI vertebra caused unilateral vertebral artery 2-segment dissection-occlusion, while in our second patient, a stab injury caused direct vertebral artery compression and dissection. The occlusion of the vertebral artery did not cause neurological symptoms in any of the cases. In both of our cases, parent vessel occlusion was performed at the level of the vertebral artery injury before the neurosurgical operation.

Preoperative Opioid Use Increases Postoperative Opioid Demand, but Not Length of Stay After Spine Trauma Surgery.

BACKGROUND: Preoperative opioid use has been well-studied in elective spinal surgery and correlated with numerous postoperative complications including increases in immediate postoperative opioid demand (POD), continued opioid use postoperatively, prolonged length of stay (LOS), readmissions, and disability. There is a paucity of data available on the use of preoperative opioids in surgery for spine trauma, possibly because there are minimal options for opioid reduction prior to emergent spinal surgery. Nevertheless, patients with traumatic spinal injuries are at a high risk for adverse postoperative outcomes. This study investigated the effects of preoperative opioid use on POD and LOS in spine trauma patients. METHODS: 130 patients were grouped into two groups for primary comparison: Group 1 (preoperative opioid use, N = 16) and Group 2 (no opioid use, N = 114). Two subgroups of Group 2 were used for secondary analysis against Group 1: Group 3 (no substance abuse, N = 95) and Group 4 (other substance abuse, N = 19). Multivariable analysis was used to determine if there were significant differences in POD and LOS. RESULTS: Primary analysis demonstrated that preoperative opioid users required an estimated 97.5 mg/day more opioid medications compared to non-opioid users (P < 0.001). Neither primary nor secondary analysis showed a difference in LOS in any of the comparisons. CONCLUSIONS: Preoperative opioid users had increased POD compared to non-opioid users and patients abusing other substances, but there was no difference in LOS. We theorize the lack of difference in LOS may be due to the enhanced perioperative recovery protocol used, which has been demonstrated to reduce LOS.

Long-term outcomes after surgery for subaxial cervical spine injuries in octogenarians, a matched population-based cohort study.

PURPOSE: We aimed to investigate surgical outcomes in octogenarians with subaxial cervical spine injuries and determine the predictors of complications and mortality. METHODS: Eligible for inclusion were all patients surgically treated between 2006 and 2018, with either anterior or posterior fixation for subaxial spine injuries. A cohort of octogenarians was identified and matched 1:1 to a corresponding cohort of younger adults. Primary outcomes were perioperative complications and mortality. RESULTS: Fifty-four patients were included in each of the octogenarian and younger groups (median age: 84.0 vs. 38.5). While the risks for surgical complications, including dural tears and wound infections, were similar between groups, the risks of postoperative medical complications, including respiratory or urinary tract infections, were significantly higher among the elderly (p < 0.05). Additionally, there were no differences in operative time (p = 0.625) or estimated blood loss (p = 0.403) between groups. The 30 and 90-day mortality rates were significantly higher among the elderly (p = 0.004 and p < 0.001). These differences were due to comorbidities in the octogenarian cohort as they were revoked when propensity score matching was performed to account for the differences in American Society of Anesthesiology (ASA) grade. Multivariable logistic regression revealed age and ASA score to be independent predictors of complications and the 90-day mortality, respectively. CONCLUSIONS: Octogenarians with comorbidities were more susceptible to postoperative complications, explaining the increased short-term mortality in this group. However, octogenarians without comorbidities had similar outcomes compared to the younger patients, indicating that overall health, including comorbidities, rather than chronological age should be considered in surgical decision-making.

Neurosurgical Injuries Associated with Recreational Horseback Riding: A 6-year Retrospective Analysis.

INTRODUCTION: Horseback riding can cause severe brain and spinal injuries. This study aimed to identify the spectrum of neurosurgical injuries related to recreational horseback riding. METHODS: A retrospective study was performed utilizing the University of Puerto Rico neurosurgery database to identify patients who were consulted to the neurosurgery service between 2018 and 2023 after a horse fall during recreational activities. The outcome upon discharge using the modified Rankin scale (mRS) was documented. Descriptive statistics were used to report frequency and median values. RESULTS: The neurosurgery service evaluated and managed 112 patients with a horseback riding fall-related injury during 6 years. Ninety-eight (87.5%) patients were male. The patients' median age was 31.5 (IQR 22-40). There were 89 head injuries (79.5%), 19 spinal injuries (17%), and 4 combined head/spine injuries (3.5%). Forty percent of the patients were admitted to inpatient care with a median length of stay of 7 days (IQR 3-17). Twenty-four patients (21%) required surgery. Upon discharge, 86.6% of the patients had an mRS grade of 0-2, 3.6% had a grade of 3, 1.8% had a grade of 4, and 1.8% had a grade of 5. Seven patients (6%) died (mRS grade 6). CONCLUSIONS: Most neurologic injuries involve isolated trauma to the head. Fifteen percent of the riders' falls were caused after the horse was impacted by a motor vehicle. Forty percent of the patients require admission and 21% undergo surgery. Ten percent of the patients had a poor mRS grade of 4- to 6 when discharged.

Multi-institutional review of characteristics and management of gunshot wounds to the spine.

BACKGROUND CONTEXT: Gunshot wounds (GSWs) to the vertebral column represent an important cause of morbidity and mortality in the United States, constituting approximately 20% of all spinal injuries. The management of these injuries is an understudied and controversial topic, given its heterogeneity and lack of follow-up data. PURPOSE: To characterize the management and follow-up of GSWs to the spine. STUDY DESIGN/SETTING: A multi-institutional retrospective review of the experience of two urban Level 1 trauma centers. PATIENT SAMPLE: Patients with GSWs to the spine between 2010-2021. OUTCOME MEASURES: Measures included work status, follow-up healthcare utilization, and pain management were collected. METHODS: Charts were reviewed for demographics, injury characteristics, surgery and medical management, and follow-up. Statistical analysis included T-tests and ANOVA for comparisons of continuous variables and chi-square testing for categorical variables. All statistics were performed on SPSS v24 (IBM, Armonk, NY). RESULTS: A total of 271 patients were included for analysis. The average age was 28 years old, 82.7% of patients were black, 90% were male, and 76.4% had Medicare/Medicaid. The thoracic spine (35%) was most commonly injured followed by lumbar (33.9%) and cervical (25.6%). Cervical GSW was associated with higher mortality (p<.001); 8.7% of patients developed subsequent osteomyelitis/discitis, 71.3% received prophylactic antibiotics, and 56.1% of cervical GSW had a confirmed vertebral or carotid artery injury. ASIA scores at presentation were most commonly A (26.9%), D (20.7%), or E (19.6%), followed by C (7.4%) and B (6.6%). 18.8% of patients were unable to be assessed at presentation. ASIA score declined in only 2 patients, while 15.5% improved over their hospital stay. Those who improved were more likely to have ASIA B injury (p<.001). Overall, 9.2% of patients underwent spinal surgery. Of these, 33% presented as ASIA A, 21% as ASIA B, 29% as ASIA C, and 13% as ASIA D. Surgery was not associated with an improvement in ASIA score. CONCLUSIONS: Given the ubiquitous and heterogeneous experience with GSWs to the spine, rigorous attempts should be made to define this population and its clinical and surgical outcomes. Here, we present an analysis of 11 years of patients presenting to two large trauma centers to elucidate patterns in presentation, management, and follow-up. We highlight that GSWs to the cervical spine are most often seen in young black male patients. They were associated with high mortality and high rates of injury to vertebral arteries and that surgical intervention did not alter rates of discitis/osteomyelitis or propensity for neurologic recovery; moreover, there was no incidence of delayed spinal instability in the study population.

Comparison of iCT-based navigation and fluoroscopic-guidance for atlantoaxial screw placement in 78 patients with traumatic cervical spine injuries.

BACKGROUND CONTEXT: Studies have shown biomechanical superiority of cervical pedicle screw placement over other techniques. However, accurate placement is challenging due to the inherent risk of neurovascular complications. Navigation technology based on intraoperative 3D imaging allows highly accurate screw placement, yet studies specifically investigating screw placement in patients with traumatic atlantoaxial injuries are scarce. The aim of this study was to compare atlantoaxial screw placement as treatment of traumatic instabilities using iCT-based navigation or fluoroscopic-guidance with intraoperative 3D control scans. METHODS: This was a retrospective review of patients with traumatic atlantoaxial injuries treated operatively with dorsal stabilization of C1 and C2. Patients were either assigned to the intraoperative navigation or fluoroscopic-guidance group. Screw accuracy, procedure time, and revisions were compared. RESULTS: Seventy-eight patients were included in this study with 51 patients in the navigation group and 27 patients in the fluoroscopic-guidance group. In total, 312 screws were placed in C1 and C2. Screw accuracy was high in both groups; however, pedicle perforations > 1 mm occurred significantly more often in the fluoroscopic-guidance group (P = 0.02). Procedure time was on average 23 min shorter in the navigation group (P = 0.02). CONCLUSIONS: This study contributes to the available data showing that navigated atlantoaxial screw placement proves to be feasible as well as highly accurate compared to the fluoroscopic-guidance technique without prolonging the time needed for surgery. When comparing these data with other studies, the application of different classification systems for assessment of screw accuracy should be considered.

Contemporary Outcomes and Patterns of Injury Associated With Parachuting Accidents.

BACKGROUND: Skydiving is an increasingly popular recreational activity in the United States and worldwide. While it is considered a high-risk sport, the United States Parachute Association reported a fatality of .28 per 100 000 jumps in 2022. Although mortality rates are low, the true rate of survivable injuries is unknown. Injuries requiring hospitalization are not uncommon and may be underreported in the literature. Anticipating these injuries and analyzing short-term outcomes following parachuting accidents would be useful for the development of mitigation strategies and to increase the safety of jumpers. METHODS: A retrospective cohort review of 126 consecutive patients presenting to a Level II Trauma Center after skydiving accidents between 2016 and 2023. Patient baseline characteristics, patterns of injury, surgical procedures, and in-hospital outcomes were reviewed. RESULTS: A total of 126 patients were included. One hundred and seventeen patients (93%) presented immediately following the accident, 65 (51.6%) were trauma activations, and 14 (11.1%) patients experienced loss of consciousness. Fractures of the lower extremity occurred in 57 (45%), fractures of the spine 48 (38%), upper extremity 13 (10%), pelvis 11 (9%). Of the spinal injuries, 10 injuries occurred in the cervical spine, 16 thoracic, 22 lumbar, 5 sacral, and 3 coccygeal spine. Eleven patients (9%) suffered multilevel spine injuries. Mean injury severity score was 7 (range 0-75). A third of patients required at least 1 surgical procedure (n = 43, 34%). Median length stay was 2 days (IQR 1, 5). Of patients who survived to our trauma center, there were two mortalities, both due to catastrophic intracranial hemorrhage. DISCUSSION: Although the 30-day mortality rate for patient who presented to our trauma center is low, it can bear significant risks including major injury. The most common injuries were lower extremity and spinal in origin with a third of patients overall requiring at least one operation.

Is Routine Use of External Spinal Orthoses Necessary After Operative Stabilization of Cervical Spine Injuries?

STUDY DESIGN: Retrospective Review. OBJECTIVE: The purpose of this study is to evaluate the efficacy of postoperative cervical orthoses to prevent fixation failure and loss of reduction after operative treatment of cervical spine fractures. SUMMARY OF BACKGROUND DATA: While cervical orthoses are most times tolerated in trauma patients, it is not clear that postoperative bracing is effective at reducing the rate of fixation failure or nonunion in this patient population. Cervical collars may delay rehabilitation, increase the risk of dysphagia and aspiration, and can contribute to skin breakdown. METHODS: All patients who underwent operative stabilization for cervical spine injuries at a single institution between January 2015 and August 2019 were identified through the institutional Research Electronic Data Capture (REDcap) database. Patient data, including cervical spine injury, surgery, post-operative orthosis use, and secondary surgeries for loss of reduction or infection, were recorded for all patients meeting the inclusion criteria. The primary outcome was the loss of reduction or failure of fixation, requiring revision surgery. Statistical analysis was performed using Jamovi (Version 1.1) statistical software. RESULTS: In all, 201 patients meeting inclusion and exclusion criteria were identified within the study period. Overall, 133 (66.2%) patients were treated with a cervical orthosis postoperatively and 68 (33.8%) patients were allowed to mobilize as tolerated without a cervical orthosis. Fixation failure and loss of reduction occurred in 4 (1.99%) patients. Of these 4, three patients were treated with a cervical orthosis postoperatively. There was no significant difference in the risk of instrumentation failure between patients in the postoperative orthosis and no orthosis groups ( P =0.706). CONCLUSION: The use of cervical orthoses after operative stabilization of cervical spine injuries remains controversial. There was no statistically significant difference in hardware failure or loss of fixation between patients treated in cervical orthoses postoperatively and those who were not.

The sensitivity of limited-sequence magnetic resonance imaging in identifying pediatric cervical spine injury: A Western Pediatric Surgery Research Consortium multicenter retrospective cohort study.

INTRODUCTION: Clinical clearance of a child's cervical spine after trauma is often challenging because of impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) is the criterion standard for excluding ligamentous injury in children but is constrained by long image acquisition times and frequent need for anesthesia. Limited-sequence magnetic resonance imaging (LSMRI) is used in evaluating the evolution of traumatic brain injury and may also be useful for cervical spine clearance while potentially avoiding the need for anesthesia. The purpose of this study was to assess the sensitivity and negative predictive value of LSMRI as compared with criterion standard full-sequence MRI as a screening tool to rule out clinically significant ligamentous cervical spine injury. METHODS: We conducted a 10-center, 5-year retrospective cohort study (2017-2021) of all children (0-18 years) with a cervical spine MRI after blunt trauma. Magnetic resonance imaging images were rereviewed by a study pediatric radiologist at each site to determine if the presence of an injury could be identified on limited sequences alone. Unstable cervical spine injury was determined by study neurosurgeon review at each site. RESULTS: We identified 2,663 children younger than 18 years who underwent an MRI of the cervical spine with 1,008 injuries detected on full-sequence studies. The sensitivity and negative predictive value of LSMRI were both >99% for detecting any injury and 100% for detecting any unstable injury. Young children (younger than 5 years) were more likely to be electively intubated or sedated for cervical spine MRI. CONCLUSION: Limited-sequence magnetic resonance imaging is reliably detects clinically significant ligamentous injury in children after blunt trauma. To decrease anesthesia use and minimize MRI time, trauma centers should develop LSMRI screening protocols for children without a reliable neurologic examination. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

Penetrating head and spine injuries due to artisanal Sahelian metal arrows: experience from a tertiary hospital in Niger.

BACKGROUND AND OBJECTIVE: Metal arrows are medieval weapons typically used for hunting and war. The incidence of metal arrow wounds has declined considerably since the 16th century. Different metal arrowheads exist, and the traditional Sahelian arrowhead is barbed. Extraction of this type of metal arrow is challenging because of the risk of extensive damage to surrounding structures. To the best of our knowledge, there are no guidelines in the literature for intracranial and spinal penetrating Sahelian arrow injuries and their surgical extraction. Most authors referred to the principles of common trauma injury. In this study, we aimed to share our experience with the surgical extraction of intracranial and spinal artisanal Sahelian arrows leading to penetrating injuries, and to propose some guidelines for such lesions. METHODS: We present a consecutive case series of 8 patients admitted to the Department of Neurosurgery of the National Hospital of Zinder for metal arrow injuries of the head and spine between November 2015 and June 2023. RESULTS: Eight patients with penetrating head and spine barbed-arrow injuries were admitted to our department. Mean age was 19.37 years (range, 15 to 25 years). Patients were all male, from a rural area. Trauma circumstances involved fighting between farmers and herders. All patients received antibiotics, analgesics and tetanus prophylaxis at admission before undergoing surgical extraction under general anesthesia. Successful extraction was achieved in all cases. CONCLUSION: Extraction of intracranial or spinal artisanal Sahelian arrows is a challenge, particularly in limited facility structures. The proposed guidelines may lead to good extraction outcomes.

Development of a Novel Risk Stratification Score to Predict 30-Day Mortality in Cervical Trauma Patients: CLAAD Score.

STUDY DESIGN: Case control. OBJECTIVE: Traumatic cervical spine injuries are associated with a substantial risk of mortality. The aim of this study is to develop a novel mortality prediction model for patients with cervical trauma who require operative treatment. SUMMARY OF BACKGROUND DATA: Patients with cervical spine trauma have a high risk of postoperative complications and mortality. There are few reliable systems that can accurately predict mortality after surgery for cervical spine trauma, and those that do exist are typically not specific to cervical trauma. MATERIALS AND METHODS: The National Surgical Quality Improvement Program (NSQIP) database was used to identify patients undergoing surgery for cervical spine trauma. Univariate analyses were performed to identify variables associated with mortality. Variables that were found to be significant in the univariate models were compiled into a multivariable model. The final model was compared with the American Society of Anesthesiologists (ASA), a modified Charlson comorbidity index (mCCI), and the 5-factor modified frailty index (mFI-5) in respect to predicting 30-day mortality after cervical trauma. The score was then externally validated using the Nationwide Inpatient Sample (NIS) database. RESULTS: Fifty-five (6.7%) of 822 patients did not survive 30 days after surgery. The final multivariable logistic regression model consisted of the following variables: circumferential fusion "C." long "L" fusion (more than 4 levels), anemia "A," age over 60 "A," and dialysis "D." The risk of mortality increased with increasing CLAAD score, with mortality rates of 0.9%, 3.1%, 7.4%, 22.7%, and 14.3% for scores of 0, 1, 2, 3, and 4, respectively. The CLAAD model had an AUC of 0.73 for predicting mortality after cervical trauma. CONCLUSIONS: The CLAAD score is a simple and effective system that can help identify patients at risk of increased mortality within 30 days of cervical trauma. LEVEL OF EVIDENCE: Level III.

Analysis of Neurosurgical Injuries and The Lessons Learned After the Catastrophic Double Earthquakes in Turkey.

AIM: To identify the patterns and types of neuorosurgical injuries sustained by victims of the double earthquakes affected ten cities with a population of 15 million in southern and central Türkiye. MATERIAL AND METHODS: In this descriptive observational study, we retrospectively analyzed the medical records of a university hospital located in one of the ten cities affected by the earthquake. RESULTS: A total of 1,612 patients with earthquake-related injuries were admitted during the study period, of which 139 (8.6%) had neurosurgical injuries. The mean age of the patients was 42.4 ± 21.1 years (median, 42 years), and 53.2% of them were female. Of the 139 patients with neurosurgical injuries, 41 (29.5%) had craniocerebral injuries, 95 (68.3%) had spinal injuries, and three (2.2%) had both craniocerebral and spinal injuries. A total of 31 surgeries were performed (22.3%) (five [3.6%] for craniocerebral injuries and 26 [18.7 %] for spinal injuries). Ninety-eight patients (70.5%) had concomitant systemic traumas. The overall mortality rate was 5.75%, with crush syndrome (n=4, 50%), being the leading cause of death, followed by neurosurgical pathologies (n=3, 37.5%) and pneumonia with septic shock (n=1, 12.5%). CONCLUSION: Neurosurgical injury is an important cause of post-earthquake mortality and morbidity. To ensure efficient medical rescue and judicious resource allocation, it is essential to recognize the characteristics of earthquake-related neurosurgical injuries. This study provides valuable information regarding the incidence, characteristics, and outcomes of neurosurgical injuries in earthquake-affected patients. Our findings highlight the need for prompt diagnosis and management of such injuries, particularly in those with concomitant systemic trauma.

Adverse events after surgery for injuries to the subaxial cervical spine: analysis of incidence and risk factors.

PURPOSE: To determine the incidence of severe surgical adverse events (sSAE) after surgery of patients with subaxial cervical spine injury (sCS-Fx) and to identify patient, treatment, and injury-related risk factors. METHODS: Retrospective analysis of clinical and radiological data of sCS-Fx patients treated surgically between 2010 and 2020 at a single national trauma center. Baseline characteristics of demographic data, preexisting conditions, treatment, and injury morphology were extracted. Incidences of sSAEs within 60 days after surgery were analyzed. Univariate analysis and binary logistic regression for the occurrence of one or more sSAEs were performed to identify risk factors. P-values < .05 were considered statistically significant. RESULTS: Two hundred and ninety-two patients were included. At least one sSAE occurred in 49 patients (16.8%). Most frequent were sSAEs of the surgical site (wound healing disorder, infection, etc.) affecting 29 patients (9.9%). Independent potential risk factors in logistic regression were higher age (OR 1.02 [1.003-1.04], p = .022), the presence of one or more modifiers in the AO Spine Subaxial Injury Classification (OR 2.02 [1.03-3.96], p = .041), and potentially unstable or unstable facet injury (OR 2.49 [1.24-4.99], p = .010). Other suspected risk factors were not statistically significant, among these Injury Severity Score, the need for surgery for concomitant injuries, the primary injury type according to AO Spine, and preexisting medical conditions. CONCLUSION: sSAE rates after treatment of sCS-Fx are high. The identified risk factors are not perioperatively modifiable, but their knowledge should guide intra and postoperative care and surgical technique.

Validation of the AO Spine CROST (Clinician Reported Outcome Spine Trauma) in the clinical setting.

PURPOSE: To evaluate feasibility, internal consistency, inter-rater reliability, and prospective validity of AO Spine CROST (Clinician Reported Outcome Spine Trauma) in the clinical setting. METHODS: Patients were included from four trauma centers. Two surgeons with substantial amount of experience in spine trauma care were included from each center. Two separate questionnaires were administered at baseline, 6-months and 1-year: one to surgeons (mainly CROST) and another to patients (AO Spine PROST-Patient Reported Outcome Spine Trauma). Descriptive statistics were used to analyze patient characteristics and feasibility, Cronbach's α for internal consistency. Inter-rater reliability through exact agreement, Kappa statistics and Intraclass Correlation Coefficient (ICC). Prospective analysis, and relationships between CROST and PROST were explored through descriptive statistics and Spearman correlations. RESULTS: In total, 92 patients were included. CROST showed excellent feasibility results. Internal consistency (α = 0.58-0.70) and reliability (ICC = 0.52 and 0.55) were moderate. Mean total scores between surgeons only differed 0.2-0.9 with exact agreement 48.9-57.6%. Exact agreement per CROST item showed good results (73.9-98.9%). Kappa statistics revealed moderate agreement for most CROST items. In the prospective analysis a trend was only seen when no concerns at all were expressed by the surgeon (CROST = 0), and moderate to strong positive Spearman correlations were found between CROST at baseline and the scores at follow-up (rs = 0.41-0.64). Comparing the CROST with PROST showed no specific association, nor any Spearman correlations (rs = -0.33-0.07). CONCLUSIONS: The AO Spine CROST showed moderate validity in a true clinical setting including patients from the daily clinical practice.
