1. Chest Wall Resection Prosthesis Daniel Haberek, University of Rhode Island, BME 281 Sec 1

2. What is Chest Wall Resection? A surgery that requires the removal of ribs and possibly the sternum Depending on the amount of rib cage removed, reconstruction may be required Prostheses are required in the most severe cases

3. Who needs Chest Wall Resection? The most common reasons of resection correlate to cancerous tumors on the ribs/lungs Other causes include breast cancer and trauma http://www.sciencedirect.com.uri.idm.oclc.org/science/article/pii/S0003497502035270

4. Why Chest Wall Resection? In most cases, the surgery is required in order to retain proper function of the lungs The ribcage serves to protect the lungs With trauma, the surgery is required to restore the lost ribs

5. The Tools In the past, grafts were popular Tissue from the body was re-purposed Now, prostheses are used These prostheses are designed by use of pre- operative CT scans http://icvts.oxfordjournals.org.uri.idm.oclc.org/content/18/1/145/F1.expansion.html http://ejcts.oxfordjournals.org.uri.idm.oclc.org/content/48/4/e92/F1.expansion.html

6. The Surgery After building the prosthetic, the resection is performed The prosthetic is then inserted and anchored Mesh is then used to secure the prosthetic and skin tissue is repositioned http://icvts.oxfordjournals.org.uri.idm.oclc.org/content/18/2/234/F2.expansion.html

7. Issues While the procedure has advanced since its 18 th century origins, there are still issues Many patients still experience harmful post-operative side effects http://www.sciencedirect.com.uri.idm.oclc.org/science/article/pii/S0003497502035270?np=y

8. The Future Within three recent cases, patients underwent chest wall resection with good results All three left the hospital within a week, and experienced no surgery-related postoperative issues In the most recent case, a 3D printed prosthetic was used, paving the way for how the prostheses can be manufactured in the future
