Background: Robotic surgery (RS) may offer benefits compared with freehand/conventional surgery (FS) in the treatment of patients with spinal disease. The aim of this study was to evaluate the efficacy and safety of RS versus FS in spinal fusion.
Methods: A systematic review and meta-analysis was performed. Data analysis and risk of bias assessment were analysed using REVMAN V5.3.
Results: We found 11 randomised clinical trials involving 817 patients (FS: 408, RS: 409). The main diagnosis was degenerative spine disease. SpineAssist, Renaissance (Mazor Robotics), Tianji Robot and TiRobot robots (TINAVI Medical Technologies) were used. Pedicle screw placement within the safety zone (grades A + B according to the Gertzbein and Robbins scale) ranged from 93% to 100% in FS versus 85-100% in RS (relative risk 1.01, 95% CI 1.00-1.03, p = 0.14). Regarding intervention time, the meta-analysis showed a mean difference (MD) of 6.45 min (95% CI -13.59 to 26.49, p = 0.53). Mean hospital stay was MD of -0.36 days (95% CI -1.03 to 0.31, p = 0.30) with no differences between groups. Contradictory results were found regarding fluoroscopy time, although there seems to be a lower radiation dose in RS versus FS (p < 0.05). Regarding safety, the studies included surgical revision frequency.
Conclusions: No conclusive results were found suggesting that there are benefits in using RS over FS for spinal fusion. Further research with adequate patient selection, robot type and quality-of-life variables is needed.
Level Of Evidence: level 1.

Objective: The potential of robot-assisted (RA) single-position (SP) lateral lumbar interbody fusion (LLIF) warrants further investigation. This study aimed to assess the efficacy of RA-SP-LLIF in improving both clinical and radiographic outcomes in patients undergoing lumbar spinal fusion surgery.
Methods: A total of 59 patients underwent either RA-SP-LLIF (n = 31 cases) or traditional LLIF (n = 28 cases).

Objective: This study aimed to introduce and evaluate a novel software-based system, BioTrace, designed for real-time monitoring of thermal ablation tissue damage during image-guided radiofrequency ablation for hepatocellular carcinoma (HCC).
Methods: BioTrace utilizes a proprietary algorithm to analyze the temporo-spatial behavior of thermal gas bubble activity during ablation, as seen in conventional B-mode ultrasound imaging. Its predictive accuracy was assessed by comparing the ablation zones it predicted with those annotated by radiologists using contrast-enhanced computed tomography (CECT) 24 hours post-treatment, considered the gold standard.

Objective: Hypertension, a common chronic disease, often leads to serious complications. While conventional management relies on antihypertensive drugs, which can cause side effects and adherence issues, alternative treatments like herbal medicine are gaining attention. This study examines the efficacy and safety of modified Saengmaeksan, an East Asian herbal remedy, in treating hypertension.

Objective: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social communication differences and restricted interests. One proposed biologic mechanism underlying ASD is oxidative stress, leading to the clinical use of glutathione based on anecdotal reports of improved behavior in autistic children. In this pilot study, we tested this observation using a randomized clinical trial format to collect preliminary data on glutathione safety and efficacy.
