  1. Role of 3D Printing in Scoliosis Correction Surgery Scoliosis is a medical condition in which a person's spine has a sideways curve. The curve is usually "S" or "C" shaped. Scoliosis occurs most often during the growth spurt just before puberty. In some cases, the person suffering from the disease can be left unable to stand up straight, to walk, or even, in the most severe cases, to breathe properly. In the most severe scoliosis cases, however, surgery is the only option. Back surgery is never a minor procedure, and scoliosis surgery is especially tricky, as it requires screws or wires to be placed throughout multiple vertebrae and then connected to stabilize the back Fig: Scoliosis Example 3D printing has done quite a bit to make scoliosis treatment less agonizing for even severe cases. Here is an over view of how 3D Printing is a complete package in diagnosing, treatment and rehabilitation for scoliosis patients. · 3D Printed Patient Specific Models for Pre-Surgical Planning Recognition of complex anatomical structures in scoliosis can sometimes be difficult to attain from simple 2D radio-graphic views. 3D models of patients’ anatomy facilitate this task and allow doctors to familiarize themselves with a specific patient. This approach proved to reduce drastically OT time, especially in complex scoliosis cases. Getting to know patients’ anatomy before entering an OT allows to plan the exact approach, helps to predict bottlenecks and even test procedures beforehand. Fig: Scoliosis Pre operative model to be 3D Printed. No standard models nor 2D images can replace 3D printing as the first do not represent the specific case in debate and the latter may hide important details, especially in the spatial relationship between structures. 3D prints may be as well used by a doctor to explain to a patient his or her condition. Offering a patient possibility to understand his case and procedure may be reassuring and produce better treatment outcome by reducing stress and insecurity. · 3D Printed Patient Specific Surgical Guides in Scoliosis Another recent advancement in the 3D Printing applications for spine surgeries are the 3D-printed Patient specific pedicle screw guides, realized in a customized manner with 3D printers. Their aim is to orient and guide in a precise fashion the placement of the screw in the pedicle. In complex scoliosis cases and revision surgeries it is very difficult to find the pedicle and the entry point for the screw guides. 3D Printing addresses this challenge and proves to be accurate, this level of accuracy is absolutely useful for patients with scoliosis, whose common anatomical landmarks can be in an abnormal position or might be not easily recognizable. Fig: Patient specific 3D printed guides. The guides involve surgical planning and software assisting surgical placement of pedicle screws designed specifically for a patients' unique anatomy. It is essentially a 3D printed surgical tool that fits the patient's unique anatomy. The 3D Printed surgical guides are printed in SLS and are bio compatible to be used on the patient's body. It is easy to see how these new customizable tools can greatly improve Scoliosis Surgery outcomes. These enhanced tools promise to improve patient satisfaction and physician performance, using the tailor-made patient-specific guides for the spine vertebrae utilizing proprietary CT scan algorithms and sophisticated 3-D medical printing technology. · 3D Printed Patient Specific Braces for Scoliosis Moderately severe scoliosis (30-45 degrees) in a child who is still growing may require bracing. The main goal of 3D Printed scoliosis brace is to combine fashion, design, and technology to create a brace far more appealing to patients, and, as a result, far more effective medically. Fig: 3D Printed scoliosis Brace. The 3D Printed patient specific brace represents a meaningful innovation in scoliosis treatment. Using advanced 3D scanning and printing technology, the Scoliosis Brace addresses the most common objections to traditional bracing. The 3D Printed braces are usually printed in SLS (Selective Laser Sintering) for its strength durability and aesthetic features along with bio compatibility. This is what happens when Design innovation meets Medical Innovation. To conclude the use of three dimensional printing in scoliosis surgeries has a wide range of applications from pre operative models to patient specific guides and orthotics proving to be a complete package in aiding Scoliosis surgeries and treatment.

  3. Difference Between 3D Medical Printing and Bioprinting The first three-dimensional (3D) printer was invented by Charles Hull in 1984. In the next 30 years, the technology advanced rapidly and evolved into a $3.07 billion industry by the end of 2013. The 2014 Wohler’s report expects this number to grow to $12.8 billion by 2018 and exceed $21 billion by 2020. Unlike the past, the use of 3D printing technology is not limited to prototyping and development of traditional consumer products such as cars and electronics. The technology has also revolutionized the field of medicine as scientists and healthcare professionals are using 3D printing to print everything from prosthetics and surgical instruments to medications and biological tissues. The goal is to develop highly specific therapeutics to manage complex illnesses and injuries. What is 3D Medical Printing? A variety of 3D printers are available in the market today. While some versions are highly versatile, others have been specifically designed to create a particular type of product. Traditional 3D medical printers use inorganic compounds such as polymer resins, metal, plastic, ceramic and rubber among other things. The printer will deposit the desired materials on a substrate in a specific pattern that is based on the texture and the dimensions of the target object. Users often rely on scanned images of the target to obtain accurate measurements. Research labs, surgeons and corporations have used this technology to create surgical instruments, implants and models of various tissues and organs. How is Bioprinting Different? Traditional 3D medical printing and bioprinting are obviously inter-related and somewhat similar to each other. In fact, many people use the terms interchangeably. While both printers use the same basic additive printing technology, bioprinting and 3D printing differ significantly at the implementation level mainly because of the type of raw materials they use. Bioprinters have been designed to deposit biological materials such as organic molecules, bone particles, cells and other extracellular matrices on a desired substrate. Unlike traditional 3D medical printing, this process involves complex designing and extensive scaffolding as it aims to generate multicellular structures that mimic the real tissue in structure and function. In most cases, the printer should be maintained within a controlled environment to retain the viability of the product. Organovo is a leading company in the field of bioprinting. Currently, bioprinting technology is being used to print tissue fragments, dental and bone implants, medications, and prosthetics. The products can be customized as per the specific needs of the patient or the research study. Many pharmaceutical companies are using bioprinted tissue fragments to understand the actual impact of medications and other therapeutics at the cellular level. Surgeons are also hopeful that the highly compatible bioprinted implants and tissues will increase the success rates of transplantation surgeries. In fact, many products are already undergoing clinical trials. As per TechNavio, a leading market research company, the bioprinting industry will grow at the rate of 14.52 percent between 2013 and 2018. Along with 3D medical printing, it is helping surgeons and other healthcare professionals understand the human body in great detail. The two technologies are complementing each other and are evolving together to change medicine forever. Sources:

    Double aortic arch is a relatively rare congenital cardiovascular malformation. Double aortic arch is an anomaly of the aortic arch in which two aortic arches form a complete vascular ring that can compress the trachea and/or esophagus. Embryologically, the aorta's right sided 4th arch failed to regress which resulted in this double aortic arch and vascular ring. Depending on how tight the ring is, symptoms in infancy are related to respiratory compression, compared to a later presentation in childhood or adulthood of swallowing difficulty. Please see the related STL file for 3D printing double aortic arch blood pool model. There are 3 separate files so the heart can be printed in slices. A fourth STL files is for 3D printing the whole heart model. The three part model has holes for magnets, which can be used to connect and separate the pieces. A US quarter is shown for scale in the images below.

  5. SME is holding an inaugural conference in about a week and a half, titled “Building Evidence for 3D Printing Applications in Medicine.” It’s sponsored by Materialize, a company that develops software for 3D printing and produces 3D-printed projects for researchers, clinicians, and consumers. This is a crucial topic for doctors, patients, and the medical 3D printing industry. 3D printing will not be widely accepted in the clinic without compelling, systematic evidence that it is better than existing technologies and improves outcomes for patients. This type of evidence is also needed to gain reimbursement approval from insurance companies. According to a blog post on the Materialize website for hospitals, the goal of the conference is to “work on a common set of guidelines regarding methodologies and assessment methods” for gathering clinical evidence of outcomes of the use of 3D printing in medicine. Because each device manufactured by 3D printing is different, and the planning stage has a great impact on the outcome, the problem of developing standardized guidelines for collecting clinical evidence is challenging. As we’ve seen here at, the promise of 3D printing to help a great number of patients makes this problem worth pursuing. One of the speakers in the following video, Andy Christensen, a business strategist for medical devices, 3D printing, and medical imaging, gets into the specifics of what types of evidence will be needed, “In medicine, the evidence 3D printing technologies should focus on gathering, will include things like overall patient outcomes, the invasiveness of the procedure, the total cost of the procedure, and things like revision rates for surgeries or other procedures. Now, while some of these are fairly easy, some of these may be fairly difficult to gather, and I think that’s a good reason a collaborative effort to gather information will be best.” Developing a collaborative effort to gather information is the goal of the conference. Over two days, the conference will feature the clinical, engineering, and economic perspectives on the major thrusts of medical 3D printing: 3D printed anatomical models, 3D printed instruments and surgical guides, and 3D printed patient-specific implants. There will be many opportunities for discussion. Representatives from government agencies, the FDA and NIH, will join industry and clinical professionals to share their thoughts. This initiative is part of the SME Medical Manufacturing Innovations Program (MMI) and the group will organize ongoing discussions online. The conference will be co-located with RAPID, the annual SME 3D-printing conference, so that people can conveniently attend both. RAPID will of course also have many sessions on 3D printing for medical applications. There’s still time to register to attend the RAPID conference held at the Orange County Convention Center in Orlando, Florida, on May 16-19. The “Building Evidence for 3D Printing Applications in Medicine” conference was only open to supporters and people significantly involved in 3D printing with relevant perspectives, through an application process. will continue to follow the outcomes of this highly relevant conference.
