Randomized, Prospective and Multicenter Clinical Study for the Clinical Evaluation and Cost-effectiveness Analysis of 3D Digital Surgery in Traumatology and Orthopedic Surgery
Randomized, Prospective and Multicenter Clinical Study for the Clinical Evaluation and Cost-effectiveness Analysis of 3D Digital Surgery in Traumatology and Orthopedic Surgery
Digital surgery, in combination with patient specific instrumentation (PSI) is being used more and more in traumatology due to its proven benefits and applications. Nowadays, medical case planning and an optimal preparation before surgery are still a challenge for surgeons. This lack of preparation is translated into longer surgical procedures, potential complications, unnecessary sterilization of materials and a high number of fluoroscopies. 2D techniques such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) and X-rays remain essential for medical planning, however, in many cases, a 3D visualization is needed to achieve better results, especially in complex cases.The use of personalized medical instruments such as surgical guides has proven to increase clinical accuracy, assuring a better correction of bone deformities, and allowing a more precise location of implants and screw positioning. Furthermore, the use of 3D-printed patient-specific prosthesis can lead to better clinical outcomes as they reduce the number of complications as well as they present a longer lifespan compared to conventional generic implants.Despite the potential of 3D technology in the medical field, there is still a lack of robust studies that compares clinical benefits between digital surgery and conventional 2D surgery, and its economic impact is still unknown. Thus, the investigators propose this randomized, prospective and multi-center clinical study to evaluate the use of 3D technology in traumatology. The aim of this project is to prove that digital surgery is a cost-effective methodology and therefore it should be adopted by the public health system as a gold standard procedure.
3D technology is increasingly being used, especially in orthopaedic surgery and traumatology as it allows to define specific objects and to understand structures and system dynamics. From patient TC images and using a biomedical engineering software, an exact 3D virtual model of the anatomical region can be created, enabling visualization, planning and simulation of the entire surgery. Besides, this software allows to design custom-made surgical guides (that precisely define cutting zones and screw positioning) as well as personalized implants that perfectly fit the patient's anatomy. After that, Patient-Specific Instrumentation can be manufactured using 3D printers and biocompatible materials and they can be sterilized to be used in the operating room.
While personalized surgical guides increase surgical precision and surgeon satisfaction, personalized implants have shown to generate better clinical outcomes, both short and long term. Despite of the benefits that 3D technology can generate in the medical field, most surgeons still opt for conventional 2D planning techniques, free-hand surgeries and generic implants use. This results in a non-standardized and variable procedure that heavily depends on the surgeon´s experience and in many cases, the obtained results deviate from the initial goals. Scientific evidence shows that a lack of precision is strictly related to clinical complications. Poor alignment of the implants can cause damage to internal structures, increases chances of dislocations, fractures and osteolysis as well as reduces the prosthetic component lifespan. That translates into patient suffering from chronic pain, reduced functionality and an increased number of reinterventions.
Regardless of the potential and several applications of 3D technology, there´s still a lack of clinical evidence, and the economic impact is still unknown. This methodology is increasingly being used as a routine medical process in many institutions but still raises concerns regarding costs, specially when considering its use in the public health system. Although digital surgery has a wide variety of associated expenses such as hardware and software cost, equipment maintenance and 3D-specialised engineers, the cost of 3D technology has significantly decreased in the past few years and it can potentially generate economic benefits compared to the standard methodology due to the optimization of the surgical process; shorter surgeries, reduced number of unnecessary sterilized materials, reduced number of fluoroscopies during surgery and less medical complications and revisions.
Thus, a large-scale study is still needed to demonstrate: 1) clinical benefits that 3D technology can generate compared to conventional surgery and 2) thoroughly analyse its economic impact to determine if it's a cost-effective methodology. For this reason, a multi-centre, randomized and prospective study is proposed to evaluate digital surgery's clinical results and to perform a cost-effectiveness analysis in order to obtain enough scientific evidence to be able to escalate the use of 3D technology in all public health institutions.
This clinical trial is a pragmatic study that will evaluate the efficacy and effectiveness of 3D technology in 3 different surgical procedures; distal radius osteotomy, acetabular arthroplasty and spinal arthrodesis.
Inclusion Criteria:
