Chair: Bauback Safa, MD
Instructors: Rudolf F. Buntic, MD; Aida Garcia Gomez, MD; Carlos Augusto Arroyo Sanchez, MD; Nora Barrett, OTR/L, CHT

Advances in Small Joint Arthroplasty
Chair: A. Lee Osterman, MD
Instructors: David A. Kulber, MD; Nina Suh, MD; Micheal Hayton, MD; Sheri B. Feldscher, OT, CHT
MCP and PIP joint arthroplasty have gone through an evolution of materials and designs. There is also some debate, as well as surgeon preference, to surgical approaches for placing these implants; especially when it comes to PIP joint arthroplasty. Outcomes for these patients can be challenging and the primary outcome of pain relief has been fairly reliable with range of motion being much more unpredictable. This course will review the indications and surgical techniques of MCP, PIP and DIP joint arthroplasty, as well as how to optimize outcomes in the small joint arthroplasty patient. Consideration of surface replacement implants, silicone implants and meniscus allograph will be presented. The course will also discuss potential pitfalls and complications, and try to provide pearls for avoiding such situations. The final part of this instructional course lecture will then review what to do when you do run into complications and what salvage options are available. We will discuss the gamut of revision arthroplasty all the way to fusion. Appropriate rehabilitation based on approach and implant will be highlighted.

Moderator: Bauback Safa, MD
Panelists: James P. Higgins, MD; Scott Levin, MD; Amy M. Moore, MD; Pedro Cavadas, MD
Trauma or oncologic resection in the extremities can lead to significant challenges for the reconstructive surgeons, where the ultimate outcome may be suboptimal or result in less function than intended. The panel will highlight the teaching points from mistakes made in extremity reconstruction: how plans can be derailed by unexpected events and how reconstructive surgeons can change the course for patients in these challenging situations. From our failures, we can learn to better help others in the future.
