ORTHOPEDIC SURGEONS AT MAURY REGIONAL THE FIRST IN TENNESSEE TO USE ZIMMER® PATIENT SPECIFIC INSTRUMENTS
COLUMBIA, Tenn. – Dr. James Wiesman and Dr. Fredrick Wade, orthopedic surgeons on the medical staff at Maury Regional Medical Center (MRMC), are the first in Tennessee to utilize Zimmer® patient specific instruments (PSI) for knee replacement. Dr. Wiesman conducted the first procedure with this technology on June 9.
Zimmer® PSIs utilize MRI technology and pre-operative planning tools to create customized cutting guides that are tailored to each patient’s unique anatomy. These guides are compatible with Zimmer® implants, including the gender-specific knee designed especially for women, and ensure accurate placement of the knee.
“In order to develop the customized surgical tools, we obtain MRI images of the hip, knee and ankle to determine the mechanical axis alignment of the patient’s leg. These images are then loaded into a software program that provides the surgeon with precise three dimensional computer imagery of the knee used to create custom pin cutting guides for the specific anatomy of the patient,” said Wiesman.
Anita Hamby of Columbia was the first patient to benefit from the use of Zimmer® PSIs and elected to have the gender-specific knee implant that is designed to address the difference in shape and tracking for a woman’s knee.
“Before my surgery, I couldn’t walk or enjoy shopping. I was miserable,” said Hamby. “I trusted my surgeon and his recommendation. I’ve known others who had knee replacement and feel like I was up and moving more quickly. Why would anyone want to choose anything different when these products are made specifically to fit you?”
This technology has only been available in the past few months and Drs. Wiesman and Wade are the first in Tennessee to use the Zimmer® product.
Dr. Fredrick Wade stated, “New technology such as patient specific instrumentation gives surgeons options on choosing the right implant and technology based on the needs of the individual patient. The orthopedic surgeons on the medical staff at Maury Regional stay abreast of the latest techniques. We have more options for patients than ever before and work with them to plan a course of treatment that best suits their needs,” said Wade.
