Capitola, Calif., June 7, 2012 – As minimally invasive surgery for hip replacement steadily increases in the U.S., physician successes and patient demand is driving the adoption of a new method where no muscle is cut, according to experts at Santa Cruz Orthopaedic Institute.
At the recent American Academy of Hip and Knee Surgeons (AAHKS) annual meeting in Las Vegas, studies presented show that as many as 16 percent of members are performing ASI or direct anterior hip arthroplasty – up from 8 percent in last year’s annual meeting.
“Many AAHKS members report patients are doing their own research and asking for the ASI approach by name,” said Dr. Nicholas Abidi, who founded Santa Cruz Orthopaedic Institute in 2002. “One member, a surgeon in Kentucky, presented his data noting that he went from doing 20 hip replacements per year to over 250 after adopting the ASI replacement approach a few years ago.”
“ASI hip replacement spares the muscles and tendons and provides immediate stability in the hip replacement, so there’s no need for dislocation precautions,” said Abidi. “If patients are comfortable, they can be fully ambulatory on day one – getting up and walking, going up and down stairs and crossing their legs.”
Abidi added that he has even been able to discharge some patients on the day of surgery. In many cases, they are able to go home the next day or by two days after surgery. A number of these patients have undergone previous standard approach replacement on their opposite hip and comment on how much less pain and dysfunction is experienced with the ASI approach.
In the anterior approach – ASI hip arthroplasty – the incision is made over the front of the hip, allowing the surgeon to separate and go between the muscles instead of cut through them. This approach decreases hip dislocation issues, speeds recovery and eases pain.
Dislocation continues to be the major complicationof the standard posterior and anterior-lateral approaches to hip replacement. Since the muscles are weakened, there is more pain, patients typically have a longer hospital stay, and physical therapy must be cautious.
With ASI hip approach, surgeons use an OSI HANA radiolucent operating room table to assist in patient positioning. The X-ray intensification during the implant placement allows the surgeon to confirm positioning of the acetabular (cup) and femoral (thigh) components. Ideal component placement can result in decreased dislocation rates as well as improved longevity of the hip replacement parts by decreasing abnormal stresses on the metal and plastic hip components.
