Mayo Clinic Researchers 3D Printing Models & Surgical Guides for Chest Wall Reconstructive Surgery6/27/2019 Mayo Clinic Researchers 3D Printing Models & Surgical Guides for Chest Wall Reconstructive Surgery https://ift.tt/2FCcF85 In the recently published ‘3D printed modeling contributes to reconstruction of complex chest wall instability,’ researchers from the Mayo Clinic Rochester look into new methods for creating 3D printed models and surgical planning devices for the treatment of complex conditions, pointing toward the example case of a 55-year-old male who underwent resuscitative thoracotomy after developing a pulmonary hernia—a condition usually caused by part of the lung bulging or tearing into the surrounding wall. The researchers 3D printed two different models during the case study, with one demonstrating anterior fractured cartilage, and the right side acting as a mirror for the ‘normal ribs’ to demonstrate misalignment of the other side. The models were used to plan the surgery, involving a thoracotomy incision and more. Chest trauma often requires surgical stabilization of rib fracture (SSRF). 3D printing has been reported as useful during intricate cases in the past for creating chest wall prostheses, but not with reconstruction using standard surgical tools.
The patient studied during this research had actually been stabbed, causing the trauma to his left chest area—also resulting in cardiac arrest. Surgery was performed, but the pulmonary hernia developed later and was repaired in a second procedure. He continued to be in pain, however, especially when laughing or coughing or stretching. As surgeons prepared to restore his chest wall with plates and bicortical screws, they used 3D printed models consisting of:
The models offered a clear perspective for the surgeons regarding areas like the disruption at the costosternal joint which was causing left chest distortion. As they continued to study the 3D printed models, the doctors were able to decide on their surgical approach. The authors point out, however, that reconstruction of the chest wall is a complicated procedure, ‘fraught with difficulties,’ to include:
With 3D modeling, however, surgeons can optimize the entire surgical and possible implantation process too.
As 3D printed models can be printed from the medical facility, all the benefits of 3D printing technology are recognized from affordability in production to speed to customization—and best of all, patient-specific treatment.
3D printing holds a special place in the world of medicine as the technology has made such sweeping changes in the way medical professionals are able to diagnose and treat other medical issues too like brain tumors, examine heart conditions with cardiac patches, and even create devices like 3D printed protheses for children with undeveloped eyes—and countless other issues making life much more tolerable for patients around the world.
