Findings Help Predict Longevity of Hip Implants
LOS ANGELES, Calif. (February 1, 2012) â€“ Pivotal research into age-related wear of total hip replacement implants, performed by a research team at the Joint Replacement Institute, has won The Hip Societyâ€™s prestigious Frank Stinchfield Award.
The study was led by medical student Andrew Battenberg during his rotation at the Joint Replacement Institute (JRI) last year, under the direction of preceptor Thomas P. Schmalzried, MD, medical director of the JRI. Research findings were gathered by affixing computerized two-dimensional accelerometers on the ankles of hip replacement patients to measure their walking mechanics. Like a highly evolved pedometer, the accelerometers measure movement remotely, based on the principle popularized by the cardiology holter monitor.
The award for the research paper, â€śCross-linked Polyethylene: Life Tested 13 Years and 37 Million Cycles,â€ť will be presented at the American Academy of Orthopaedic Surgeons (AAOS) conference in San Francisco on Feb. 11. Lead author Battenberg, his preceptor Dr. Schmalzried, and co-authors Jeffrey S. Hopkins, MD and Andrew D. Kupiec will be invited to receive the Stinchfield research award.
Dr. Schmalzried described Andrew Battenberg as â€śgoldâ€ť among medical students who apply for rotations at the JRI every year. Andrew performed a thorough, time-intensive study of hip replacement patients, measuring both patientsâ€™ movement with the accelerometers and analyzing X-ray images of their implants. Findings indicate that, as people age, their level of activity decreases and, proportionally, so too does the wear on their implants.
â€śLike a set of tires on a car, we would suspect that mileage declines year over year and so does the wear on the tread,â€ť said Dr. Schmalzried.
The JRI groupâ€™s study manuscript will now be processed by Clinical Orthopaedic and Related Research and readied for publication in about a year.
