“…The availability of a 3D printed model can also be a fundamental aid in the placement of screws or surgical plates, mainly thanks to the possibility of testing in advance of the procedure; examples include pedicle screw placement in a clinical case of severe congenital scoliosis 23 or, more in general, applications to spinal surgery 24, 25 with the aim of designing PS surgical guides.…”

Advances in image processing have led to the clinical use of 3D printing technology, giving the surgeon a realistic physical model of the anatomy upon which he or she will operate.Relying on CT images, the surgeon creates a virtual 3D model of the target anatomy from a series of bi-dimensional images, translating the information contained in CT images into a more usable format.3D printed models can play a central role in surgical planning and in the training of novice surgeons, as well as reducing the rate of re-operation.Cite this article: Auricchio F, Marconi S. 3D printing: clinical applications in orthopaedics and traumatology.

“…There is a limited but growing body of work concerning innovative uses within orthopaedics and trauma surgery, for example, for preoperative planning [27], particularly in spinal surgery where placement of screws requires extreme accuracy [28]. Custom fabrication of orthopaedic jigs using RP techniques has now become a commercially viable option for arthroplasty of the knee as introduced by Biomet with the Signature knee system in collaboration with Materialise.…”

Rapid prototyping (RP) is applicable to orthopaedic problems involving three dimensions, particularly fractures, deformities, and reconstruction. In the past, RP has been hampered by cost and difficulties accessing the appropriate expertise. Here we outline the history of rapid prototyping and furthermore a process using open-source software to produce a high fidelity physical model from CT data. This greatly mitigates the expense associated with the technique, allowing surgeons to produce precise models for preoperative planning and procedure rehearsal. We describe the method with an illustrative case.

“…In the studies reviewed, time taken to create the models ranged from 5 hours to 2 days, with extra costs anywhere between $300 and >$1,000 (10,11,13,18,20,22,26,27). Izatt et al (14) stated that these additional costs were offset in 59% of cases by the more Figure 1 Flow chart of literature search performed using PRISMA methodology (9).…”

“…A full-scale, stereoscopic understanding of the pathology allows for more detailed planning and simulation of the procedure (10)(11)(12)(13)(14)(15)(16)(17)(18)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(50)(51)(52). Assessing complex pathologies on a model overcomes many of the issues associated with traditional 3D imaging, such as the lack of realistic anatomical representation and the associated complexity of computer-related skills and techniques (10,12).…”

“…The main reasons given for reduced operation time included a more evolved understanding of the pathology, such as location and surgical approach, and the facilitation of pre-operative instrumentation decisions (14,16,(18)(19)(20)(21)24,27,28,50). Other clinical benefits such as improved diagnosis, reduction in fluoroscopy time, better communication within the surgical team and lower rates of screw misplacement have been reported when compared with the use of conventional imaging in pre-operative planning (11,14,20,26,30). Izatt et al (14) found that the use of a 3DP biomodel improved surgical outcomes in 78% of cases, though this is contradicted by Li et al (23) who reported no change in complication rates or clinical outcomes.…”

Systematic review of 3D printing in spinal surgery: the current state of play

et al. 2017

View full text Add to dashboard Cite

Three-dimensional printing (3DP), also known as "Additive Manufacturing", is a rapidly growing industry, particularly in the area of spinal surgery. Given the complex anatomy of the spine and delicate nature of surrounding structures, 3DP has the potential to aid surgical planning and procedural accuracy. We perform a systematic review of current literature on the applications of 3DP in spinal surgery. Six electronic databases were searched for original published studies reporting cases or outcomes for 3DP surgical models, guides or implants for spinal surgery. The findings of these studies were synthesized and summarized. These searches returned a combined 2,411 articles. Of these, 54 were included in this review. 3DP is currently used for surgical planning, intra-operative surgical guides, customised prostheses as well as "Off-the-Shelf" implants. The technology has the potential for enhanced implant properties, as well as decreased surgical time and better patient outcomes. The majority of the data thus far is from low-quality studies with inherent biases linked with the excitement of a new field. As the body of literature continues to expand, larger scale studies to evaluate advantages and disadvantages, and longer-term follow up will enhance our knowledge of the effect 3DP has in spinal surgery. In addition, issues such as financial impact, time to design and print, materials selection and bio-printing will evolve as this rapidly expanding field matures.
