BACKGROUNDThree-dimensional (3D) printing is currently being explored in various medical fields with promising results, and customized surgical instrument prototyping and production seems to be one of the promising approaches, particularly in pediatric surgery. This study aimed to test the possibility of desktop 3D printing of surgical instruments for use in pediatric surgery. MATERIAL and METHODSRoux retractor and infant laparoscopic trocar were designed using Solidworks 3D CAD software (Dassault Systemes, FR). Mechanical durability simulation tests were performed using Solidworks Simulation software. The instruments were printed in Ultimaker 2+ Extended 3D printer (Ultimaker, NL) using 2.85-mm polylactic acid filaments. RESULTSRoux retractor was designed in 15 min and printed in 90 min. Laparoscopic trocar was designed in 2 h and printed in 2 h. Application of 5-kilogram force (kgf) resulted only in 0.84-mm displacement in infant laparoscopic trocar. The 5 kgf applied to the Roux retractor's curved face caused 9.22-mm displacement. The laparoscopic trocars weighed 7.40±0.07 g, and Roux retractors weighed 12.50±0.04 g. The interior chamber of the 3D-printed laparoscopic trocars withstood a mean of 10±1.5 mmHg pressure without any obvious air leakage. Poststerilization culture results of all prototypes were proven to be sterile. CONCLUSION3D printing of surgical instruments is a promising field in pediatric surgery as it offers a great versatility regarding both design and production.

“…As 3DP technology continues to become cheaper, faster and more accurate, its use in the setting of spinal surgery is likely to become routine, and in a greater number of procedures (1)(2)(3)(4)6,42,44,65). Lower cost desktop 3D printers for everyday use could soon be a reality, aiding real-time model and implant creation for more personalised surgical care (46,48).…”

“…A variety of techniques can be used to print physical models from three-dimensional renderings based on CAD software, and STL design files. Whilst the use of this technology in medicine is still in its infancy, 3DP offers the possibility of revolutionising healthcare with its ability to rapidly create customized shapes from a wide range of materials (1)(2)(3)(4)(5)(6).…”

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

et al. 2017

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.

“…Having gained much interest in recent years, 3DP has found applications in many surgical and medical fields, with variations in printing solutions permitting various options in the architecture of the final structure across a wide range orthopaedic and facial or plastics procedures (1,2). The application of 3DP in orthopaedics is only recent, with positive early results demonstrating the potential to alter future orthopaedic practice (3,4). Custom 3DP of prosthesis for spinal surgery has a potential significant impact due to customisation of complex shapes and materials to manage complex pathologies (5)(6)(7).…”

The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for C1/ C2 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including degenerative disc and facet disease when conservative methods are unsuccessful.However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology.3DP refers to a process where three-dimensional objects are created through successive layering of material, so called 'additive manufacturing'. Although this technology enables accurate fabrication of patient-specific orthopaedic and spinal implants, literature on its utilization in this regard is rare. A 65-year-old female, with severe facet arthropathy at the C1/C2 level, osteophyte formation and impingement of the exiting C2 nerve root underwent a C1/C2 posterior fusion and rhizolysis of the C2 nerve roots. A custom posterior fixation implant was designed and on-laid over the C2 spinous process and lamina, with screw holes made to a depth and angulation that was pre-calculated based on the preoperative CT based 3D modelling. The patient had an uneventful recovery and reported a significant reduction in occipital neuralgia and sub-occipital pain and 2-month follow-up. We report the first case of a customized 3DP spinal prosthesis for posterior C1/ C2 fusion. The implant added significant value reducing the overall time of the procedure, and safety with a reduced risk of neurovascular compromise.
