Rib Cage Stabilisation With 3D-Printed Polyethylene Sternal Prosthesis Post-Sternotomy Mediastinitis

Three-dimensional technologies in chest wall resection and reconstruction

Resection and reconstruction of the chest wall can pose unique challenges given its vital role in the protection of the thoracic viscera and the dynamic part it plays in respiration. A number of new three-dimensional (3D) technologies may be invaluable in tackling these challenges. Herein we review the use of 3D technologies in preoperative imaging with virtual 3D models, printing of 3D models for preoperative planning, and printing of 3D prostheses when approaching complex chest wall reconstruction.

Attachment Issues: A Case Report of a Promising Sternal Implantation with 3D-printed Polyethylene

Sternal reconstruction is beneficial for chest wall stability, respiratory function, and cosmetics, with no superior prosthesis or method thus far identified. We present a case of sternal reconstruction in a patient 6 years post sternal removal using a 3D-printed, patient-specific, polyethylene prosthesis with reasonable short-term outcomes. We believe a polyethylene prosthesis shows advantages over other materials and is worth further investigation, providing a technique for attaching said prosthesis to the native tissues is established.

Establishing Quality and Safety in Hospital-based 3D Printing Programs: Patient-first Approach

The adoption of three-dimensional (3D) printing is rapidly spreading across hospitals, and the complexity of 3D-printed models and devices is growing. While exciting, the rapid growth and increasing complexity also put patients at increased risk for potential errors and decreased quality of the final product. More than ever, a strong quality management system (QMS) must be in place to identify potential errors, mitigate those errors, and continually enhance the quality of the product that is delivered to patients. The continuous repetition of the traditional processes of care, without insight into the positive or negative impact, is ultimately detrimental to the delivery of patient care. Repetitive tasks within a process can be measured, refined, and improved and translate into high levels of quality, and the same is true within the 3D printing process. The authors share their own experiences and growing pains in building a QMS into their 3D printing processes. They highlight errors encountered along the way, how they were addressed, and how they have strived to improve consistency, facilitate communication, and replicate successes. They also describe the vital intersection of health care providers, regulatory groups, and traditional manufacturers, who contribute essential elements to a common goal of providing quality and safety to patients. ©RSNA, 2021.
