Carry out an update and systematic review on the use of three-dimensional printing (3DP) in spinal surgery. ⋯ 3DP is one of the most-used tools in spine surgeries, but there are still randomized articles available on the subject. Using this technology seems to have a positive effect on patient education regarding their disease and surgical planning.

Deep brain stimulation (DBS) is a well-established treatment for motor circuit disorders such as Parkinson disease, dystonia, and essential tremor, particularly when pharmacological interventions are insufficient.1-3 The increase in DBS-related publications and the growing number of patients receiving DBS highlight the acceptance and refinement of the procedure.3,4 Despite its widespread use, comprehensive anatomical knowledge of deep brain nuclei remains critical for enhancing clinical efficacy. Accurate targeting of the complex three-dimensional anatomy of the target nuclei is crucial for maximizing therapeutic effects and minimizing adverse side effects. However, existing anatomical guides often lack depth perception.5,6 We dissected specimens prepared using the Klingler method,7 proceeding sequentially from lateral to medial, medial to lateral, and superior to inferior. ⋯ Our models were evaluated via augmented reality within a real-world context, and radiological models of these nuclei generated through segmentation were analyzed. Thus, our models and videos offer a novel method for visualizing the complex anatomy of deep brain nuclei, which could help enhance the precision of DBS procedures and may improve patient outcomes. This advanced understanding of spatial anatomical relationships may be beneficial for the continued development and success of DBS therapy.

Radiographic methods for evaluating skeletal maturity traditionally include the Risser sign and the hand-wrist maturation method. While the cervical vertebral maturation (CVM) stage is widely recognized in orthodontics, its application in assessing spinal growth, particularly in adolescent idiopathic scoliosis (AIS), has been less explored. This study explores the correlation between CVM, chronological age, and the Risser sign to evaluate the feasibility of CVM in assessing skeletal development in adolescents. ⋯ The CVM stage, which shows a strong correlation with Risser sign grading, could serve as a reliable alternative for assessing skeletal maturity in adolescent subjects, particularly in clinical scenarios where minimizing radiation exposure is a priority.

The middle meningeal artery (MMA) is a major dural vessel that plays a significant role in developing chronic subdural hematomas (cSDHs). Understanding its variable anatomy is essential for the effective management of cSDH and the prevention of complications. ⋯ The most common configuration of MMA was Adachi-type IC. The MMA most often originated from the maxillary artery. The posterior branch of the MMA was typically dominant and most frequently originated from the distal segment. There was no significant impact of Adachi type on treatment results or fluoroscopy time.

Radiographic adjacent segment disease (ASD) ranges from 10% to 84%, depending on technique. Occurrence of symptomatic ASD is lower, with a range of 1.9% to 13%. ASD can be very debilitating and necessitate further procedures, leading to high morbidity. Herein, we explore the occurrence of adjacent segment disease when performing anterior column release in lateral interbody fusion. ⋯ Higher PI-LL mismatch after lumbar interbody fusion, and performance of an ACR during LLIF increased the likelihood of developing symptomatic ASD in our patients. Considering ACR to achieve the goal of correcting spinopelvic parameters should be carefully evaluated when undertaking a lateral approach.
