“…The emerging and increasingly popular field of additive manufacturing, also known as 3D printing, has been introduced to the medical community in many forms, including medical models for surgical training 13 and medical implants. 9 Recently, a patient-specific 3D-printed titanium implant was used to treat traumatic distal tibia bone loss.…”

“…Synthetic materials that have now been described to approach the physical properties of heart tissue include silicone 5 and polyvinyl alcohol. 6 Both of these materials can currently not be directly 3D printed but rather require the 3D printing of a mold, which is used to reproduce the required anatomical structure. These techniques may not be ideal for printing an entire anatomically accurate heart but rather for the component parts separately.…”

“…To ensure that the heart myocardium remained relatively flexible, the inner myocardium was hollowed out, thus maintaining the anatomical geometry while also allowing a degree of flexibility of the material. We chose TPU because as compared to silicone or polyvinyl alcohol, materials closer to the hearts own physical properties, 5,6 it is tougher and in preliminary testing allowed for multiple needle stitches and retraction without tearing easily.…”

Objective The right anterior lateral thoracotomy (RALT) approach for aortic valve replacement provides excellent outcomes in expert hands while avoiding sternal disruption. It, however, remains a technically demanding niche operation. Instrument trajectories via this access are influenced by patient anatomy, the intercostal space chosen, and surgical retraction maneuvers. Methods To simulate the typical surgical maneuvers, on an anatomically accurate model, and to measure the instrument trajectories, we generated a 3-dimensional (3D) printed model of the heart and chest cavity. A simulated approach to the base of the right coronary sinus via the medial-second intercostal, the lateral-second intercostal, or third intercostal space was made. Keeping the instrument in place, 3D scans of the models and geometrical measurements of the instrument trajectories were performed. Results The 3D scans of the 3D printed model showed a high fidelity when compared to the original computed tomographic scan image geometry (mean deviation of 1.26 ± 1.27mm). The instrument intrathoracic distance was 75 mm via the medial-second, 115 mm via the lateral-second, and 80 mm via the third intercostal space. The 3D angulation of the instrument to the incision was 33.77o, 55.93o, and 38.4o respectively. The distance of the instrument to the lateral margin was 12, 26, and 5 mm respectively. The cranial margin of the incision was always a limiting margin for the instrument. Conclusions Three-dimensional printing and 3D scanning facilitated a realistic simulation of the instrument trajectory during RALT approach. The lateral-second intercostal approach showed the most favorable approach angle and distance from the lateral margin, although it also had the longest intrathoracic distance.

“…This is especially important in MISS training where there is a steep learning curve associated with limited exposure around delicate structures [20]. Other MIS fields have shown the utility 3DP of biomodels including cardiothoracic surgery [21], cranial neurosurgery [22], and otolaryngology [23]. Additionally, surgical simulation with biomodels provides a venue for testing new materials and techniques.…”

Purpose of Review To summarize the recent advances in 3D printing technology as it relates to spine surgery and how it can be applied to minimally invasive spine surgery. Recent Findings Most early literature about 3D printing in spine surgery was focused on reconstructing biomodels based on patient imaging. These biomodels were used to simulate complex pathology preoperatively. The focus has shifted to guides, templates, and implants that can be used during surgery and are specific to patient anatomy. However, there continues to be a lack of long-term outcomes or cost-effectiveness analyses. 3D printing also has the potential to revolutionize tissue engineering applications in the search for the optimal scaffold material and structure to improve bone regeneration without the use of other grafting materials. Summary 3D printing has many potential applications to minimally invasive spine surgery requiring more data for widespread adoption.
