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: Augmented reality (AR) in medical imaging is a significant development that overlays digital images onto real-world pictures or videos. This article demonstrates the workflow of a minimally invasive microsurgical tubular resection of an intradural extramedullary spinal tumor using portable intraoperative computed tomography scanner and state-of-the-art total three-dimensional computer navigation and microscope-based AR. The use of AR enhances surgical planning and visualization, resulting in successful treatment outcomes.

Summary: This study evaluated 7 patients with traumatic sacral fractures treated with robotic-assisted minimally invasive spinopelvic fixation, showing a mean blood loss of 85.7 mL and mean operative time of 178.4 minutes. Six patients had no complications postoperatively, while one patient experienced complications but all patients were safely discharged. Robotic-assisted minimally invasive spinopelvic fixation appears to be a safe and feasible treatment option for traumatic sacral fractures.

Summary: This study compared the efficacy of spinal dorsal instrumentation with intraoperative navigation using different imaging technologies. The results showed that navigation coupled with O-arm had significant advantages in accuracy over navigation with 3D C-arm fluoroscopy. Both systems still offer a high level of accuracy in screw placement.

Summary: Endoscopic spine surgery aims to achieve equivalent or better patient outcomes compared to traditional open surgery, while minimizing soft tissue disruption, blood loss, postoperative pain, and recovery time. It is used for both decompression and interbody fusion procedures across the spinal axis, with the potential for combining robotic guidance to further enhance surgical precision and outcomes.

Summary: Transpedicular screw placement is a common spine surgery technique, but misplacement rates are high. With advancing technology, navigation and robotic systems have been developed to improve accuracy and reduce revisions, radiation, and operating time. This article presents a case of using the Cirq robotic arm coupled with intraoperative navigation for accurate transpedicular instrumentation in lumbar fusion surgery.

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.
