The publication on “Patient-Specific Computed Tomography-Based Three-Dimensional Spine Trauma Models for Preoperative Planning in Virtual Reality and 3D Printing: An EANS Young Neurosurgeons' Network Study”[1] is interesting. This study shows how open-source software can be used to create patient-specific three-dimensional (3D) models from preoperative computed tomography (CT) data. It can also be used in conjunction with virtual reality (VR) and 3D printing to design and train spinal surgery procedures. To evaluate its appropriateness and broad applicability, a number of constraints should be taken into account.

The first significant drawback is that, despite being practical and reproducible, the segmentation process—which mostly uses intensity-based segmentation—may not be accurate in distinguishing intricate structures like tiny fracture fragments, articular surfaces, or areas with artifacts from severe injury. Additionally, user experience plays a major role in model refinement in 3D modeling software, which may limit database uniformity and cause interoperator variability.

Second, the sample size is still small and does not include a wide variety of injury types, such as combined injuries or patients with preexisting spinal abnormalities, even though 37 models were created across multiple levels of the spine and categorized using the AO Spine Injury Classification System. Furthermore, the developed collection of 3D patient-specific models can serve as a preoperative planning tool and a “clinical communication platform” between institutions, according to a new interpretation.

A collaborative VR environment is used to illustrate case conversations, highlighting the creative role that 3D models play in overcoming geographical limitations and enhancing shared understanding among interdisciplinary teams. This is particularly true in circumstances involving complicated spines where conventional two-dimensional (2D) images might not be sufficient. They failed to rigorously compare the models' geometric accuracy to the original CT scans.

According to a fresh interpretation, the created library of 3D patient-specific models can be used as a “clinical communication platform” between institutions as well as a preoperative planning tool. The innovative role of 3D models in overcoming geographic constraints and improving shared understanding among multidisciplinary teams is highlighted by demonstrating case discussions through a collaborative VR environment. This is especially true in complex spinal cases where traditional 2D imagery may not be adequate.

A quantitative assessment of this database's therapeutic and educational utility is advised for future research directions. This involves researching how it affects the precision of surgical planning when utilizing VR or 3D printing, treatment decision-making, and the comprehension of fracture morphology. Additionally, incorporating cutting-edge segmentation methods like artificial intelligence-assisted or semi-automated segmentation could decrease human variability and increase accuracy. Lastly, the development of uniform guidelines for the production and classification of models will be essential to the expansion of this database for future multicenter study and international application.
