Basic Science Symposium II: MEMS Technology.

Abstract

Introduction For a long time surgeons and basic scientists have been working together in developing instrumentation to restore function across a diseased human joint. In the quest to achieve their objectives during this long journey, they have developed analytical and experimental methods to quantify various parameters across a normal and a diseased joint, like the hip joint. For example, back in the late 80s and early 90s, 1-3 using crude (from today's perspective) sensor technology, a number of researchers quantified the forces across the hip after total hip arthroplasty. The findings helped the joint replacement industry in several ways including validating the analytical models, contributing to the design of implants that will last longer (hopefully for the life span of the patient), and establishing guidelines for exercise in the immediate postoperative time period. All these results have led to hip arthroplasty improvements to the point that it has become the gold standard for all other joint replacement systems. It is not a surprise that spine surgeons and engineers, with the exponential growth of the bioMEMS technology in the last 5 years, are looking into ways this technology can be used in the area of spine. Dr. Lisa Ferrara, co-organizer of this symposium, has posed questions ranging from the basic definition of bioMEMS to future/potential applications of the technology in the area of spine. The eminent panel members have provided thought-provoking responses reflecting their experiences in the area. We are fortunate that they agreed to take part in this initiative, and we thank them for their participation. I hope you will enjoy this symposium. We look forward to your comments and submission of your full length manuscripts for the coming issues of the journal.
