The aim of this study was to evaluate our experience with a high-definition 3-dimensional (3D) exoscope (EX) for cervical spine surgery versus a binocular operating microscope (OM). ⋯ Overall, our study showed that the EX appears to be a safe alternative for common ACDF with the unique advantage of excellent comfort and also serves a useful educational tool for the surgical team. However, our investigation revealed several important limitations of this system, including slightly inferior visualization and illumination quality compared with the OM.

To perform measurements in normal brain imaging studies from the free edge of the falx cerebri to the genu and the body of the corpus callosum and perform a statistical analysis based on age, type of study, and sex highlighting potential surgical implication of these measurements. ⋯ There is a distance from the free edge of the falx cerebri to the genu and body of the corpus callosum of at least 1 cm in both CT and magnetic resonance imaging studies of normal brains. Statistically significant differences were found in the measurements in relation to the type of study and in relation to age in the measurements made in CT studies. These measurements could be important in determining the extent of bone resection in certain types of decompressive craniectomies.

Patient-tailored 3D-printing models in the subspecialty training of spinal tumors: A comparative study and questionnaire survey.
Training in the subspecialty of spinal tumors is challenging and less researched. The anatomic variations and complex relationship with paraspinal structures tend to be the main obstacle for the trainees in this field. Three-dimensional (3D)-printing technique has the advantage of individual customization and high fidelity, and can produce case-tailored models as auxiliary tools in medical training. ⋯ The 3D-printing model is a valuable tool in the training of new residents and fellows in the subspecialty of spinal tumors. It can facilitate the trainees' understanding of tumor anatomy, surgical readiness, and confidence as well.

The UK neurosurgical community has a track record of delivering high-quality, practice-changing clinical research studies, facilitated by a robust clinical research infrastructure and close collaborations between neurosurgical centers. More recently, these large-scale studies have been conceived, developed, and delivered by neurosurgical trainees, working under the umbrella of the British Neurosurgical Trainee Research Collaborative (BNTRC). ⋯ Importantly, we focus on our experience of trainee-led studies, including the development of the network, current challenges, and future directions. We believe that a similar model can be applied in different settings and countries, which will drive up the quality of neurosurgical research, ultimately benefiting future neurosurgical patients.

This study aimed to evaluate the biomechanical effects of different cage positions with stand-alone (SA) methods and bilateral pedicle screw fixation (BPSF) in the osteoporotic lumbar spine after oblique lumbar interbody fusion (OLIF). ⋯ Placing the cage in the middle third of the L5 SEP for OLIF could reduce the maximum stresses of the L5 SEP, the cage, and the fixation, which may reduce the risk of postoperative cage subsidence, endplate collapse, and fixation fracture in the osteoporotic lumbar spine. Compared with SA OLIF, BPSF could provide sufficient stability for the surgical segment and may reduce the incidence of the aforementioned complications.
