Impact of Porosity on Interbody Cage Implants: PEEK and Titanium

Abstract

Lippincott Continuing Medical Education Institute, Inc., is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. Lippincott Continuing Medical Education Institute, Inc., designates this enduring material for a maximum of 1.5 AMA PRA Category 1 CreditsTM. Physicians should claim only the credit commensurate with the extent of their participation in the activity. To earn CME credit, you must read the CME article and complete the quiz and evaluation assessment survey on the enclosed form, answering at least 70% of the quiz questions correctly. This activity expires on October 31, 2023. LEARNING OBJECTIVES: After participating in this CME activity, the spine surgeon should be better able to: 1. Assess the limitations of solid polyetheretherketone (PEEK)/titanium (Ti) in interbody cage design. 2. Describe the effects of introducing porosity into PEEK/Ti interbody cages and the effect of biocompatibility and mechanical properties. 3. Interpret preclinical study results of porous PEEK/Ti interbody cages.
