Summary: This study aimed to compare the radiation exposure and time demand between robotics and navigation in minimally invasive lumbar fusion surgery. The results showed that robotics significantly reduced radiation exposure in terms of fluoroscopy time, radiation dose, and radiation percentage compared to navigation. Additionally, robotics reduced the setup and image capture time but increased the operative time, with no significant difference in the total operating room time.

Summary: Spinal surgery is shifting towards a minimally invasive paradigm, driven by various factors. Advancements in intraoperative imaging and navigation technologies have enabled the increasing use of minimally invasive surgical techniques. However, patient-specific factors may render minimally invasive approaches unfeasible, prompting researchers to optimize patient selection for optimal outcomes in minimally invasive spinal surgery.

Summary: This study reviewed 187 patients who underwent degenerative lumbar spinal surgery using minimally invasive spinal fusions techniques and found that the rate of ADTs was 11.764%. ADTs were more frequent in cases of previous surgery. The study suggests that MAST provides a certain level of protection in reducing ADTs.

Summary: The study investigated the technical aspects of microscope-assisted anterior decompression fusion and introduced a spreader system suitable for minimally invasive anterior lumbar interbody fusion (Mini-ALIF). The study included 42 patients who underwent microscope-assisted Mini-ALIF surgery and found that the technique provided good intraoperative disc exposure and improved postoperative foramen and disc height.

Summary: The study compared the effects of Traditional Open Spine Surgery and Minimally Invasive Spine Surgery on muscles and tendons, revealing differences in muscle loads and joint reaction forces between the two approaches. Individuals with fused joints should be particularly cautious during lifting, as both surgical methods have varying impacts on muscle loads and joint reactions.

Summary: This study retrospectively reviewed data from patients who underwent minimally invasive lumbar spine surgery and provided answers to frequently asked questions regarding surgical outcomes, postoperative recovery, and complications. The results showed that most patients experienced significant pain relief and functional improvement after surgery, and the majority of patients were able to be discharged and return to normal activities within a short period. These findings can be used as a reference for physicians in surgical counseling and patient education.

Summary: Hippocampal sclerosis with gray-white matter blurring in the anterior temporal lobe is associated with prolonged T1 relaxation and axonal loss. Patients without GMB in the temporal poles showed less reduction in axonal fraction on imaging compared to normal controls. Contralateral values did not differ significantly between patients and normal controls, but reduced axonal density and diameter were confirmed in the GMB-affected temporopolar white matter compared to temporal poles without GMB.

Summary: This prospective study evaluated a protocol for radiation-sparing kyphoplasty by assessing dosemetrically recorded radiation exposures to both patient and surgeon. The results showed that the implementation of a strict intraoperative radiation protection protocol allows for safely performed kyphoplasty with ultra-low radiation exposure for the patient and surgeon without exceeding the annual occupational dose limits.

Summary: Patients undergoing neurosurgical cranial approaches often experience postoperative pain, reduced mouth opening, and masticatory problems due to manipulation of the temporal muscle. A study using the Oral Health Impact Profile (OHIP14) questionnaire found that postoperative oral health-related quality of life scores increase significantly after 3 months, decrease after 15 months, and do not return to preoperative levels. Postoperative impairment in mouth opening and masticatory pain can cause feedback from patients and their dentists.

Summary: The manual measurement technique of spinal sagittal alignment on X-rays is susceptible to rater-dependent variability. This study found that different raters had different significance levels when evaluating the pre- to postoperative change of lumbar lordosis in patients receiving lumbar spondylodesis. Therefore, it is important to describe the evaluation process and validate the consistency of results through multiple raters in every publication.

Summary: This study evaluated the prognostic factors influencing the progression-free survival rates of patients with petroclival meningioma. The extent of surgical resection and postoperative radiotherapy were found to be significantly associated with improved PFS. In cases of extended petroclival meningioma with infiltration of the cavernous sinus, near total resection and additional radiotherapy also showed positive effects. Surgical resection remains the most important prognostic factor, but neurological morbidity should be considered.
