RESUMEN
INTRODUCTION: Clinical implications of screening for blunt cerebrovascular injury (BCVI) after low-energy mechanisms of injury (LEMI) remain unclear. We assessed BCVI incidence and outcomes in LEMI versus high-energy mechanisms of injury (HEMI) patients. METHODS: In this retrospective cohort study, blunt trauma adults admitted between July 2015 and June 2021 with cervical spine fractures, excluding single spinous process, osteophyte, and chronic fractures were included. Demographics, comorbidities, injuries, screening and treatment data, iatrogenic complications, and mortality were collected. Our primary end point was to compare BCVI rates between LEMI and HEMI patients. RESULTS: Eight hundred sixty patients (78%) were screened for BCVI; 120 were positive for BCVI. LEMI and HEMI groups presented similar BCVI rates (12.6% versus 14.4%; P = 0.640). Compared to HEMI patients (n = 95), LEMI patients (n = 25) were significantly older (79 ± 14.9 versus 54.3 ± 17.4, P < 0.001), more likely to be on anticoagulants before admission (64% versus 23.2%, P < 0.001), and less severely injured (LEMI injury severity score 10.9 ± 6.6 versus HEMI injury severity score 18.7 ± 11.4, P = 0.001). All but one LEMI and 90.5% of the HEMI patients had vertebral artery injuries with no significant difference in BCVI grades. One HEMI patient developed acute kidney injury because of BCVI screening. Eleven HEMI patients developed BCVI-related stroke with two related mortalities. One LEMI patient died of a BCVI-related stroke. CONCLUSIONS: BCVI rates were similar between HEMI and LEMI groups when screening based on cervical spine fractures. The LEMI group exhibited no screening or treatment complications, suggesting that benefits may outweigh the risks of screening and potential bleeding complications from treatment.

Objective: The study aimed to assess and investigate cervical spine fracture in diffuse idiopathic skeletal hyperostosis and to identify research trends in cervical spine fracture in diffuse idiopathic skeletal hyperostosis in countries around the world using bibliometric analysis. Method: We examined bibliometric data obtained from the Scopus database collection for the periods 1 January 2000 and 1 January 2022. Authors, institutions, nations, publications, keywords, and references were noted and analyzed. The total number of research articles published on the subject of diffuse idiopathic skeletal hyperostosis was used to calculate the amount of research on that subject undertaken in the study period. A sample of the publication data collected from the Scopus database was then analyzed using the Bibliometric program and used to develop a relationship chart using the Bibliometrix and VOSviewer programs. Results: The number of citations was assumed to be a qualitative measure of the publication. We estimated the impact of the research using several metrics, including the H-index, in the bibliometric analysis of authors, geographic areas, institutes, and references. A total of 52 studies related to cervical spine fractures in diffuse idiopathic skeletal hyperostosis were identified. Only 5.12% of those studies were cited in other publications, for a total of 1410 citations in publications by 342 authors, of whom only two authors had published a single study. Co-authorships occurred at 7.273%. Diseases common in elderly males were often studied retrospectively, and "Diffuse Idiopathic Skeletal Hyperostosis" was a frequently mentioned keyword. Conclusion: The findings of this study provide insights into authors, institutions, key publications, and research trends related to diffuse idiopathic skeletal hyperostosis and can potentially serve as a guide for further studies in the field. The bibliometric analysis of cervical spine fractures in patients with diffuse idiopathic skeletal hyperostosis highlights important contributors, influential papers, geographical trends, and study characteristics in this area of research.
RESUMEN
(1) Background: In elderly patients with type II odontoid fractures, accompanying severe atlantoaxial instability (AAI) is discussed as a marker possibly warranting more aggressive surgical therapy. This study aimed to characterize adverse events as well as the radiological and functional outcomes of surgical vs. conservative therapy in patients with odontoid fracture and AAI. (2) Methods: Patients aged 65 years and older with type II odontoid fracture and AAI treated were included. AAI was assumed if the mean subluxation across both atlantoaxial facet joints in the sagittal plane was greater than 50%. Data on demographics, comorbidities, treatment, adverse events, radiological, and functional outcomes were analyzed. (3) Results: Thirty-nine patients were included. Hospitalization time was significantly shorter in conservatively treated patients compared to patients with ventral or dorsal surgery. Adverse events occurred in 11 patients (28.2%), affecting 10 surgically treated patients (35.7%), and 1 conservatively treated patient (9.1%). Moreover, 25 patients were followed-up (64.1%). One secondary dislocation occurred in the conservative group (11.1%) and three in the surgical group (18.8%). (4) Conclusions: Despite the potential for instability in this injury, conservative treatment does not seem to lead to unfavorable short-term results, less adverse events, and a shorter hospital stay and should thus be considered and discussed with patients as a treatment option, even in the presence of severe AAI.
RESUMEN
INTRODUCTION: Traumatic subaxial fractures account for more than half of all cervical spine injuries. The optimal surgical approach is a matter of debate and may include anterior, posterior or a combined anteroposterior (360º) approach. Analyzing a cohort of patients initially treated with anterior cervical discectomy and fusion (ACDF) for traumatic subaxial injuries, the study aimed to identify predictors for treatment failure and the subsequent need for supplementary posterior fusion (PF). METHODS: A retrospective, single center, consecutive cohort study of all adult patients undergoing primary ACDF for traumatic subaxial cervical spine fractures between 2006 and 2018 was undertaken and 341 patients were included. Baseline clinical and radiological data for all included patients were analyzed and 11 cases of supplementary posterior fixation were identified. RESULTS: Patients were operated at a median of 2.0 days from the trauma, undergoing 1-level (78%), 2-levels (16%) and ≥ 3-levels (6.2%) ACDF. A delayed supplementary PF was performed in 11 cases, due to ACDF failure. On univariable regression analysis, older age (p = 0.017), shorter stature (p = 0.031), posterior longitudinal ligament (PLL) injury (p = 0.004), injury to ligamentum flavum (p = 0.005), bilateral facet joint dislocation (p < 0.001) and traumatic cervical spondylolisthesis (p = 0.003) predicted ACDF failure. On the multivariable regression model, older age (p = 0.015), PLL injury (p = 0.048), and bilateral facet joint dislocation (p = 0.010) remained as independent predictors of ACDF failure. CONCLUSIONS: ACDF is safe and effective for the treatment of subaxial cervical spine fractures. High age, bilateral facet joint dislocation and traumatic PLL disruption are independent predictors of failure. We suggest increased vigilance regarding these cases.

Blunt vertebral artery injuries (BVAI) associated with cervical spine fractures are often problematic due to symptoms of occlusion. Denver grade V cases, in which the vertebral artery is transected, are rare but often fatal, and treatment has rarely been reported. We encountered a case of hemorrhagic shock due to an injury to a branch of the vertebral artery associated with an upper cervical spine fracture. Transcatheter arterial embolization was performed successfully to achieve hemostasis, requiring superselective arterial embolization to preserve the main trunk of the vertebral artery. It is important to be aware that vascular injuries to the branch vessels as well as the main trunk can cause complications.
RESUMEN
INTRODUCTION: This study analyzed the incidence of secondary dislocations (sDLs) after surgical stabilization of AO Spine type B and C injuries of the subaxial cervical spine (sCS). MATERIALS AND METHODS: Patients treated for injuries of the sCS from 2010 to 2020 were retrospectively analyzed for the incidence of sDL within 60 days after first surgery. A univariate analysis of variables potentially influencing the risk of sDL was performed. Patients with solitary anterior stabilization underwent subgroup analysis. The treatment of sDLs was described. RESULTS: A total of 275 patients were included. sDLs occurred in 4.0% of patients (n = 11) in the total sample, most frequently after solitary anterior stabilization with 8.0% (n = 10, p = 0.010). Only one sDL occurred after combined stabilization and no sDLs after posterior stabilization. In the total sample and the anterior subgroup, variables significantly associated with sDL were older age (p = 0.001) and concomitant unstable facet joint injury (p = 0.020). No neurological deterioration occurred due to sDL and most patients were treated with added posterior stabilization. sDL is frequent after solitary anterior stabilization and rare after posterior or combined stabilization. DISCUSSION: Patients of higher age and with unstable facet joint injuries should be followed up diligently to detect sDLs in time. Neurological deterioration does not regularly occur due to sDL, and most patients can be treated with added posterior stabilization.
RESUMEN
STUDY DESIGN: Systematic review. OBJECTIVE: To compare the efficacy of the posterior approach and combined anterior-posterior approach in the treatment of ankylosing spondylitis (AS) with cervical spine fracture by meta-analysis. METHODS: The databases PubMed, Web of Science, Embase, and Cochrane Library were searched for studies on the comparison of the posterior approach group and the combined anterior-posterior approach group in the treatment of ankylosing spondylitis combined with cervical spine fracture from database establishment to August 2023. The procedure time, intraoperative blood loss, the rates of neurological improvement, mean change in the postoperative neurological function, complication rates, rates of revised surgery, and mortality were extracted. Meta-analysis was performed using RevMan 5.4 software provided by Cochrane Library. RESULTS: A total of 11 retrospective cohort studies with a total of 215 patients were included in this study. The posterior approach group had lower intraoperative blood loss than the combined anterior-posterior approach group [Mean difference (MD) = -146.05, 95%CI(-187.40,-104.69), P < .00001]; the operation time was significantly less in the posterior approach group than in the combined anterior-posterior approach group [MD = -95.34, 95%CI(-113.13,-77.55), P < .00001]. There were no statistically significant differences in the neurological improvement rates, mean changes in postoperative neurological function, complication rates, modified surgery rates, and mortality rates. CONCLUSION: Both the posterior approach and combined anterior and posterior approach can achieve good results. Clinicians should develop an individualized approach based on the patient's fracture type, degree of spinal cord injury, fracture stability, fracture dislocation, general condition, and underlying disease.
RESUMEN
BACKGROUND: The incidence of cervical spine fractures is increasing every day, causing a huge burden on society. This study aimed to develop and verify a nomogram to predict the in-hospital mortality of patients with cervical spine fractures without spinal cord injury. This could help clinicians understand the clinical outcome of such patients at an early stage and make appropriate decisions to improve their prognosis. METHODS: This study included 394 patients with cervical spine fractures from the Medical Information Mart for Intensive Care III database, and 40 clinical indicators of each patient on the first day of admission to the intensive care unit were collected. The independent risk factors were screened using the Least Absolute Shrinkage and Selection Operator regression analysis method, a multi-factor logistic regression model was established, nomograms were developed, and internal validation was performed. A receiver operating characteristic (ROC) curve was drawn, and the area under the ROC curve (AUC), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were calculated to evaluate the discrimination of the model. Moreover, the consistency between the actual probability and predicted probability was reflected using the calibration curve and Hosmer-Lemeshow (HL) test. A decision curve analysis (DCA) was performed, and the nomogram was compared with the scoring system commonly used in clinical practice to evaluate the clinical net benefit. RESULTS: The nomogram indicators included the systolic blood pressure, oxygen saturation, respiratory rate, bicarbonate, and simplified acute physiology score (SAPS) II. The results showed that our model had satisfactory predictive ability, with an AUC of 0.907 (95% confidence interval [CI] = 0.853-0.961) and 0.856 (95% CI = 0.746-0.967) in the training set and validation set, respectively. Compared with the SAPS-II system, the NRI values of the training and validation sets of our model were 0.543 (95% CI = 0.147-0.940) and 0.784 (95% CI = 0.282-1.286), respectively. The IDI values of the training and validation sets were 0.064 (95% CI = 0.004-0.123; P = 0.037) and 0.103 (95% CI = 0.002-0.203; P = 0.046), respectively. The calibration plot and HL test results confirmed that our model prediction results showed good agreement with the actual results, where the HL test values of the training and validation sets were P = 0.8 and P = 0.95, respectively. The DCA curve revealed that our model had better clinical net benefit than the SAPS-II system. CONCLUSION: We explored the in-hospital mortality of patients with cervical spine fractures without spinal cord injury and constructed a nomogram to predict their prognosis. This could help doctors assess the patient's status and implement interventions to improve prognosis accordingly.

Abstract Female, 85 y.o., weighting 60 kg, multiple trauma patient. After an initial laparotomy, an emergent thoracotomy was performed using a bronchial blocker for lung isolation (initial active suction was applied). During surgery, bronchial cuff was deflated, causing a self-limited tracheal blood flooding. A second lung isolation was attempted but it was not as effective as initially. Probably, a lung collapse with the same bronchial blocker was impaired in the second attempt because of the obstruction of bronchial blocker lumen by intraoperative endobronchial hemorrhage. Bronchial blocker active suction may contribute to obtain or accelerate lung collapse, particularly in patients that do not tolerate ventilator disconnection technique or lung surgical compression. The use of bronchial blockers technology was a valuable alternative to double lumen tubes in this case of emergent thoracotomy in the context of a patient having thoracic, abdominal trauma, severe laceration of tongue and apophysis odontoid fracture associated to massive hemorrhage, despite several pitfalls that could compromise its use. The authors intend to discuss the advantages and disadvantages of bronchial blockers comparing to double-lumen tubes for lung isolation, and the risks of our approach, in this complex multitrauma case.
Resumo Paciente do sexo feminino, 85 anos, 60 kg, com trauma múltiplo. Após uma laparotomia inicial, uma toracotomia de emergência foi feita com um bloqueador brônquico para isolamento pulmonar (sucção inicial ativa foi aplicada). Durante a cirurgia, o balonete brônquico foi desinflado, causou um derrame hemorrágico traqueal autolimitado. Reisolamento foi tentado, mas não foi tão eficaz como inicialmente. Provavelmente, o colapso do pulmão com o mesmo bloqueador brônquico foi prejudicado na segunda tentativa devido à obstrução do lúmen do bloqueador brônquico pela hemorragia endobrônquica intraoperatória. A sucção ativa do bloqueador brônquico pode contribuir para obter ou acelerar o colapso pulmonar, particularmente em pacientes que não toleram a técnica de desconexão do ventilador ou a compressão cirúrgica pulmonar. O uso da tecnologia de bloqueadores brônquicos foi uma opção valiosa para os tubos de duplo lúmen neste caso de toracotomia de emergência em paciente com trauma torácico e abdominal, laceração grave da língua e fratura da apófise odontoide associados a hemorragia maciça, apesar de vários riscos que poderiam comprometer seu uso. Os autores pretendem discutir as vantagens e desvantagens dos bloqueadores brônquicos em comparação com os tubos de duplo lúmen para isolamento pulmonar e quais foram os riscos de nossa abordagem neste complexo caso de múltiplo trauma.
