Despite the orthopedics markets in US and EU reaching a plateau, market size countries such as Brazil, Russia, India, China is steadily growing. As result, major orthopedic companies are shifting their focus towards these developing products tailored to needs. However, significant challenge associated with this new opportunity requirement for development of more affordable prostheses compared those sold Europe. With introduction lower-cost models into market, article aims assess performance...
Abstract Background Numerous total knee prosthetic implants are currently available on the orthopedic market, and this variety covers a set of different levels constraint: among various models available, significant role is covered by mobile bearing cruciate-retaining design with an ultra-congruent insert, design, fixed-bearing posterior stabilized prosthesis constrained condylar knee. A biomechanical comparative study them could therefore be helpful for clinical decision-making process....
Over the last several years, impact of Artificial Intelligence on world and society has been undeniable. More specifically, a subfield, known as Machine Learning (ML), is driving innovation in vast variety fields it denotes ability machine to identify relationships between data without explicit criteria, emulating human-like type learning. decade, research efforts have also focused orthopedics order provide help assistance surgeons clinicians their daily tasks. The purpose this paper serve...
To date, studies assessing the safety profile of 3D printing materials for application in cardiac ablation are sparse. Our aim is to evaluate and feasibility two biocompatible materials, investigating their potential use intra-procedural guides navigate surgical arrhythmia ablation. Herein, we printed various prototypes varying thicknesses (0.8 mm–3 mm) using a resin (MED625FLX) thermoplastic polyurethane elastomer (TPU95A). Geometrical testing was performed assess material properties pre-...
Abstract Background In revision total knee arthroplasty, addressing significant bone loss often involves the use of cemented or press-fit stems to ensure implant stability and long-term fixation. A possible alternative stem was recently introduced utilizing custom-made porous metaphyseal cones, designed reconstruct missing tibial femoral geometries. Early clinical radiological assessments have shown promising results. The objective this research biomechanically evaluate performances these...
Patient-specific three-dimensional (3D) printed models have been increasingly used in many medical fields, including cardiac surgery for which they are as planning and communication tools. To locate plan the correct region of interest bypass placement during coronary artery graft (CABG) surgery, surgeons can pre-operatively rely on different images. This article aims to present a workflow production patient-specific 3D-printed surgical guide, from data acquisition image segmentation final...
Adequate fixation is fundamental in revision total knee arthroplasty; consequently, surgeons must determine the correct set-up for each patient, choosing from numerous stem solutions. Several designs are currently available on market, but there no evidence-based quantitative biomechanical guideline yet. Therefore, several stems were designed and analyzed using a previously-validated finite-element model. The following parameters studied: design characteristics (length shape), added features...
Background: In the field of medicine, photogrammetry has played for long time a marginal role due to significant amount work required that made it impractical an extended medical use. Developments in digital occurred recent years, have steadily increased interest and application this technique. The present study aims compare reconstruction heart with computed tomography (CT) as reference. Methods: photogrammetric reconstructions images from ECG imaging derived were performed. particular,...
Abstract Purpose Robotic‐assisted surgery has been recently introduced to improve biomechanical restoration, and thus better clinical functional outcomes, after knee joint arthroplasty operations. uni‐compartmental (UKA) aims indeed surgical bone resection alignment accuracy, optimized component positioning balancing, relying on a series of calibration measurements performed during the surgery. These advantages focus therefore improving reproducibility UKA surgeries, reducing (if not...
The purpose of this study is to analyze the effects TKA under-dimensioning during daily activities. A regular ("control") size and an undersized design same fixed bearing asymmetric PS prosthesis were analyzed walking squat using finite element analysis. two models showed similar internal-external rotations antero-posterior displacements both Slightly higher displacements, wider contact areas lower pressure found in control size. Post-cam engagement angles on sizes. Changes slightly affected...
Background 3D printing technology development in medical fields allows to create models assist preoperative planning and support surgical procedures. Cardiac ischemic scar is clinically associated with malignant arrhythmias. Catheter ablation aimed at eliminating the arrhythmogenic tissue until sinus rhythm restored. The scope of this work describe workflow for a guide able define target catheter ablation. Materials methods For patient-specific heart phantom model realization, both CT scan...
Partial weight bearing is fundamental to rehabilitation in the early stages following lower limb surgery. However, it remains debated as how properly achieve partial while avoiding complications from excessive or premature load. Of devices currently on market, instrumented insoles coupled with force-sensitive resistors (FSRs) are among best options today’s clinical practice. Still, although several of these systems have been developed last few years, only some validated, leaving insufficient...
Background Due to their mechanical properties, the MED625FLX and TPU95A could be appropriate candidates for cardiac 3D surgical guide use during radiofrequency ablation (RFA) treatment. Methods RFA aims destroy heart tissue, which cause arrhythmias, by applying a (RF) energy at critical temperature above +50.0°C, where thermal damage is considered not reversible. This study analyze biomaterials properties with different thicknesses, testing response bipolar unipolar on porcine muscle samples...
Background: The lack of thermally and mechanically performant biomaterials represents the major limit for 3D-printed surgical guides, aimed at facilitating complex surgery ablations. Methods: Cryosurgery is a treatment cardiac arrhythmias. It consists obtaining cryolesions, by freezing target tissue, resulting in selective irreversible damage. MED625FLX TPU95A are two biocompatible materials guides; however, there no data on their response to cryoenergy delivery. study purpose evaluate...
