Abstract
Introduction Clinicians encounter challenges in promptly diagnosing thoracolumbar injuries (TLIs) and fractures (VFs), motivating the exploration of Artificial Intelligence (AI) and Machine Learning (ML) and Deep Learning (DL) technologies to enhance diagnostic capabilities. Despite varying evidence, the noteworthy transformative potential of AI in healthcare, leveraging insights from daily healthcare data, persists. Research question This review investigates the utilization of ML and DL in TLIs causing VFs. Materials and methods Employing Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) methodology, a systematic review was conducted in PubMed and Scopus databases, identifying 793 studies. Seventeen were included in the systematic review, and 11 in the meta-analysis. Variables considered encompassed publication years, geographical location, study design, total participants (14,524), gender distribution, ML or DL methods, specific pathology, diagnostic modality, test analysis variables, validation details, and key study conclusions. Meta-analysis assessed specificity, sensitivity, and conducted hierarchical summary receiver operating characteristic curve (HSROC) analysis. Results Predominantly conducted in China (29.41%), the studies involved 14,524 participants. In the analysis, 11.76% (N = 2) focused on ML, while 88.24% (N = 15) were dedicated to deep DL. Meta-analysis revealed a sensitivity of 0.91 (95% CI = 0.86-0.95), consistent specificity of 0.90 (95% CI = 0.86-0.93), with a false positive rate of 0.097 (95% CI = 0.068-0.137). Conclusion The study underscores consistent specificity and sensitivity estimates, affirming the diagnostic test's robustness. However, the broader context of ML applications in TLIs emphasizes the critical need for standardization in methodologies to enhance clinical utility.

Abstract
OBJECTIVE The primary objective of this investigation is to systematically scrutinize extant surgical studies delineating Four-Level Anterior Cervical Discectomy and Fusion (4L ACDF), with a specific emphasis on elucidating reported surgical indications, clinical and radiological outcomes, fusion rates, lordosis correction, and the spectrum of complication rates. METHODS The literature review was conducted in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, employing the MEDLINE (PubMed), Embase, and Scopus databases. This analysis encompasses studies implementing the 4L ACDF procedure, with detailed extraction of pertinent data pertaining to surgical methodologies, types of employed interbody cages, clinical and radiological endpoints, rates of fusion, and the incidence of complications. RESULTS Among the 15 studies satisfying inclusion criteria, a marginal increment in the year 2022 (21.4%) was discerned, with a preponderance of study representation emanating from China (35.7%) and the United States (28.6%). 50% of the studies were single-surgeon studies. Concerning follow-up, studies exhibited variability, with 42.9% concentrating on periods of five years or less, and an equivalent proportion extending beyond this timeframe. Across the amalgamated cohort of 2457 patients, males constituted 51.6%, manifesting a mean age range of 52.2-61.3 years. Indications for surgery included radiculopathy (26.9%) and myelopathy (46.9%), with a predilection for involvement at C3-7 (24.9%). Meta-analysis yielded an overall complication rate of 16.258% (CI 95%: 14.823%-17.772%). Dysphagia (4.563%), haematoma (1.525%), hoarseness (0.205%), C5 palsy (0.176%) were the most prevalent complications of 4L ACDF. Fusion rates ranging from 41.3% to 94% were documented. CONCLUSION The 4L ACDF is commonly performed to address mylopathy and radiculopathy. While the surgery carries a complication rate of around 16%, its effectiveness in achieving bone fusion can vary considerably.

Abstract
Background and Objectives: To investigate the role of augmented reality (AR) in skull base (SB) neurosurgery. Materials and Methods: Utilizing PRISMA methodology, PubMed and Scopus databases were explored to extract data related to AR integration in SB surgery. Results: The majority of 19 included studies (42.1%) were conducted in the United States, with a focus on the last five years (77.8%). Categorization included phantom skull models (31.2%, n = 6), human cadavers (15.8%, n = 3), or human patients (52.6%, n = 10). Microscopic surgery was the predominant modality in 10 studies (52.6%). Of the 19 studies, surgical modality was specified in 18, with microscopic surgery being predominant (52.6%). Most studies used only CT as the data source (n = 9; 47.4%), and optical tracking was the prevalent tracking modality (n = 9; 47.3%). The Target Registration Error (TRE) spanned from 0.55 to 10.62 mm. Conclusion: Despite variations in Target Registration Error (TRE) values, the studies highlighted successful outcomes and minimal complications. Challenges, such as device practicality and data security, were acknowledged, but the application of low-cost AR devices suggests broader feasibility.

Abstract
Aim To investigate the correlations between tumour characteristics, symptoms, intraoperative findings, and outcomes in patient with meningioma. Methods A retrospective study was conducted on 86 surgically treated patients at Department of Neurosurgery of Cantonal Hospital Zenica from 2010 to 2020. Patients with intracranial meningiomas underwent neurological evaluation and MRI scans to analyse tumour characteristics, including volume (TV), peritumoral brain oedema (PTBE) and oedema index (EI). Surgical treatment was performed, followed by postoperative MRI and outcome assessment. Intraoperatively, the tumour's relationship with cortex, pial membrane, skull bones, and sinuses was evaluated, and the extent of tumour resection was graded. Meningioma samples underwent histopathological analysis to assess the grade and regularity of borders, and Ki-67 labelling index was determined using immunohistochemistry. Results Significant correlations were found between PTBE and Ki67 expression (p<0.001), PTBE and vomiting/nausea (p=0.002), cognitive impairment (p=0.047), venous compression (p=0.001), cortical, pial and dural invasion (p<0.05), and the postoperative presence of oedema (p=0.002). Venous compression, cortical, pial, dural and bone invasion positively correlated with Ki-67 expression (p<0.001). Grade and tumour border positively correlated with Ki-67 expression (p<0.001). Oedema persistence postoperatively showed a positive correlation with Ki-67 expression (p<0.001). Conclusion The study revealed significant correlations between Ki-67 expression and PTBE, with notable associations with clinical symptoms, tumour characteristics, and postoperative oedema presence.

Abstract
Aim To investigate the correlation of body mass index (BMI) with severity of intervertebral disc degeneration. Methods The study enrolled patients who had undergone surgical intervention for a herniated disc at the Department of Neurosurgery of the Cantonal Hospital Zenica. Patients underwent thorough preoperative evaluation, including medical history, neurological and physical assessments, and radiological analysis. The surgical intervention consisted of a posterior lumbar discectomy, and the excised disc material was preserved and subjected to histopathological analysis based on Histopathologic Degeneration Score (HDS). Patients were divided in two groups according to Body Mass Index (BMI): study group with BMI≥25 and control group with BMI<25. Results Among 69 patients with herniated IVD, 26 (37.7%) were with BMI≥25 (study group), and 43 (62.3%) were with BMI<25 (controls). The study group displayed substantial increase in height, 1.80±0.06 m compared to controls, 1.74±0.06 m (p=0.001). Weight and BMI were significantly higher in the study group of patients (weight: 91.60±10.22 vs. 67.37±9.20 kg, BMI: 28±2 vs. 22±2; p<0.001). Differences were confirmed in HDS values in the study group comparing to the control group (p<0.001). The study group exhibited significant differences in chondrocyte proliferation, tears and clefts, granular changes, and mucous degeneration (p<0.05), and positive correlations were found between BMI and these alterations found in the herniated discs (p<0.05). Therefore, HDS showed positive correlations with BMI (R=0.599; p<0.001) and weight (R=0.696; p<0.001). Conclusion The study's findings confirmed that BMI has a significant impact on intervertebral disc degeneration, emphasizing the importance of weight management in preventing disc degeneration.

Abstract
This systematic review assesses current molecular targeted therapies for glioblastoma multiforme (GBM), a challenging condition with limited treatment options. Using PRISMA methodology, 166 eligible studies, involving 2526 patients (61.49% male, 38.51% female, with a male-to-female ratio of 1.59/1), were analyzed. In laboratory studies, 52.52% primarily used human glioblastoma cell cultures (HCC), and 43.17% employed animal samples (mainly mice). Clinical participants ranged from 18 to 100 years, with 60.2% using combined therapies and 39.8% monotherapies. Mechanistic categories included Protein Kinase Phosphorylation (41.6%), Cell Cycle-Related Mechanisms (18.1%), Microenvironmental Targets (19.9%), Immunological Targets (4.2%), and Other Mechanisms (16.3%). Key molecular targets included Epidermal Growth Factor Receptor (EGFR) (10.8%), Mammalian Target of Rapamycin (mTOR) (7.2%), Vascular Endothelial Growth Factor (VEGF) (6.6%), and Mitogen-Activated Protein Kinase (MEK) (5.4%). This review provides a comprehensive assessment of molecular therapies for GBM, highlighting their varied efficacy in clinical and laboratory settings, ultimately impacting overall and progression-free survival in GBM management.

Abstract
Advancements in neurosurgical visualization have been made possible by the introduction of the operating microscope (OM) and the emergence of exoscopic technology (EX). Both OMs and EXs provide enhanced magnification and illumination, but they come with their own set of advantages and disadvantages. OMs provide high-quality magnification and illumination and have been used successfully in a variety of surgical procedures. They can be customized to fit the specific needs of the surgeon and are a well-established technology. However, they can be bulky, expensive, and cause discomfort during extended procedures. EXs provide high-definition magnification and illumination, improved depth perception and ergonomics, and can be cost-effective. They can be customized to fit the specific needs of the surgeon and can be made using locally available materials, reducing the need for expensive imports. However, they may require adjustment and have a learning curve for surgeons who are used to operating with OMs. Additionally, they may have limited availability in some healthcare settings. The choice between OMs and EXs will depend on the specific needs of the surgeon and the healthcare setting. The integration of 3D EX systems has revolutionized neurosurgery, offering improved depth perception and ergonomics. EX's cost-effectiveness addresses accessibility concerns, making it an attractive alternative, particularly for low and middle-income healthcare settings. The exoscope seems to be a safe alternative compared to an operative microscope for the most common brain and spinal procedures. The exoscope may help expand access to neurosurgical care and training worldwide. In conclusion, both technologies have their own set of advantages and disadvantages, and the choice between them will depend on the specific needs of the surgeon and the healthcare setting.

Abstract
Aim To investigate morphometric determinants of lumbar canal in patients treated in Cantonal Hospital Zenica, and their variation according to gender. Methods Morphometry of lumbar spinal canal was assessed in 52 patients treated at the Department of Neurosurgery of Cantonal Hospital Zenica in the period between September 2022 and November 2022. Data were collected retrospectively: anteroposterior and transverse diameter of lumbar vertebrae and intervertebral discs, as well as anteroposterior diameter of the spinal canal. Results Gender appeared to be an important morphometric determinant, since it significantly differed when it comes to lumbar vertebral anteroposterior and transverse diameter, being mostly larger in males. Conclusion This study increases anatomical knowledge of the vertebras and spinal canal of the lumbar region. Therefore, the measured dimensions of the lumbar vertebrae and spinal canal could be used as a baseline point for evaluation of patients presenting with low back pain and potential spinal canal stenosis.

Abstract
Aim To examine a correlation of demographic characteristics of patients, preoperative modality of conservative therapy and timing on the postoperative outcome of patients six months after the operation. Methods A retrospective, non-randomized, clinical study involved 48 patients of different age and gender with a verified diagnosis of cauda equina syndrome (CES). The inclusion criteria were patients with CES caused by discus hernia. Observed research variables were age, gender, affected vertebral level, conservative modalities of perioperative therapy (nonsteroidal anti-inflammatory drugs - NSAIDs and physiotherapy), duration of symptoms, and outcome parameters (motor and sensory function, sphincter function of the urinary bladder and bowel). Results A statistically significant negative correlation was found between age and postoperative outcome (p<0.05). The affected vertebral level was positively correlated with the motor and sensory outcome (p<0.05). A positive correlation between the use of NSAIDs and the outcome was found (R=0.570; p<0.001), as well as a negative correlation with perioperative physiotherapy (R=-0.201; p= 0.001). Postponement of surgery was negatively correlated with outcome variables (p<0.001). Conclusion The results of the study bring new conclusions that were not previously observed. Possible new characteristics associated with the outcome of cauda equina syndrome were determined.
