Technology aids in Minimally Invasive Anterior Hip Replacement Procedure

With the high-tech hana Table, orthopedic surgeons at Community Hospital are taking a minimally invasive approach to total hip replacement.

Orthopedic surgeons on staff at Community Hospital in Munster are offering a minimally invasive anterior total hip replacement using the high-tech hana® Hip and Knee Arthoplasty Table.

Anterior total hip replacement, performed with the assistance of the Hana Hip and Knee Arthoplasty Table is a minimally-invasive approach as opposed to a posterior total hip replacement surgery. With its unique capability to stabilize, position, and rotate the leg, the HANA table enables the surgeon to replace the hip through a single, small incision at a natural interval among the muscle groups surrounding the hip. This space or interval allows replacement of the hip without cutting through muscles or tendons, a requirement in all other hip joint procedures.

“Using this anterior or frontal approach, we’re able to open the hip with a small 3-1/2 to 4 inch incision, part the muscles like a curtain, and replace all the hip components,” according to Gregory McComis, M.D., orthopedic surgeon at Community Hospital. “During a traditional hip replacement these muscles would be cut apart and take much longer to heal.”

The specially designed table features leg supports that give the surgeon the ability to direct adjustments on the operative leg during surgery with exact control and precision. The table is made from carbon fiber (like a golf club shaft) that allows the surgeon to x-ray and take images during the procedure. Imaging in real-time helps to ensure correct positioning, sizing and fit of the artificial hip components, as well as correct leg length.

“We can get the perfect custom fit with the right size implant in the right spot, every time,” McComis said. “Theoretically there’s less wear and tear on the hip joint, making it last longer.”

Additional benefits include less muscle trauma, less post-operative pain and a more rapid return to normal activities.

Whereas traditional total hip replacement surgery requires limited hip motion for six to eight weeks, after the anterior approach, patients can immediately bend and bear full weight at the hip. With supervised inpatient physical therapy, patients go up and down stairs before going home from the hospital. Most are able to walk without a walker or cane two weeks following surgery.

“My patients can go back and do whatever they want much sooner,” said McComis. “Today, people in their 60s are still very active and working, but may be suffering from osteoarthritis of the hip. They may be candidates for the anterior hip replacement procedure. One of the greatest advantages is that our patients are able to get up and about much more quickly.”
