Interest in Using Stem Cells in Spinal Surgery Increasing

“The world of spinal biologics is very exciting, not only because the spine has so many different tissues to regenerate, but also because the conditions that affect the spine are very different. Cost and regulatory issues, as well as efficacy and safety, are among the considerations that must be addressed,” said Wellington K. Hsu, MD, the Clifford C. Raisbeck Distinguished Professor of Orthopaedic Surgery at Northwestern University’s Feinberg School of Medicine.

MoM Biomechanical and Biologic Failure Mechanisms

The resurgence of metal-on-metal (MoM) bearings about 10 years ago was due in part to efforts to avoid the wear-associated complications of metal-on-polyethylene (MoP) bearings. MoM bearings also allowed the use of larger diameter femoral head components, which could theoretically decrease dislocation rates. MoM bearings gained approval from the U.S.

Enhancing EBM with Proprietary Technology

AAOS evidence-based medicine (EBM) products, such as clinical practice guidelines (CPGs) and appropriate use criteria (AUC), are created by and for clinicians of multiple disciplines to summarize the best available evidence for various procedures across multiple orthopaedic disease topics.

HSS Residents Learn the Research Ropes with OREF

For the orthopaedic surgery residents at New York’s Hospital for Special Surgery (HSS), conducting research is not an option. It’s a requirement. “Our mission is to train the next group of orthopaedic leaders, and research is an integral part of that,” explained HSS Orthopaedic Residency Program Director Mathias P.G. Bostrom, MD. A clinician scientist himself, Dr. Bostrom acknowledged that only some of his residents will go on to make research a part of their careers.
