Less scaring, fewer complications than traditional hip replacement procedure
You may have heard about orthopedic patients in
traction for days or weeks during recovery from surgery, but now traction during
some hip replacement procedures is allowing for faster recoveries.
Banner Good Samaritan Medical Center recently obtained the PROfx Hip
Arthroplasty table from Mizuho OSI – a surgical table designed exclusively for
hip joint surgery, including total joint replacement, acetabular fractures and
orthopedic pelvic reconstruction procedures. The table allows surgeons to
position a patient's hip and leg in traction for easier access, including an
anterior approach (from the front of the hip) as opposed to the lateral (side),
or the posterior (back) approach.
"What makes this approach unique is that the surgeon does not have to cut or
split any of the muscle fibers, thereby avoiding permanent muscle damage;
without the table it's very difficult to do this," said David Ott, M.D., an
orthopedic surgeon with Arizona Orthopaedic Associates. "Since the procedure is
done with a fluoroscope (real-time X-ray imaging), we are able to better match
the leg lengths and get a better 'fit-and-fill' of the implants into the bone.
"Through this approach, the patient's recovery is dramatically improved. Many
patients can go home the following day or two and we have seen patients return
to work within eight to 10 days," Dr. Ott added. "A typical procedure would
require a lengthier hospital stay, more time where the patient is restricted
from certain positions, and an extended rehabilitation."
Dr. Ott and his colleagues Dr. Michael Wilmink, Dr. Robert Berghoff and Dr.
Douglas Hartzler have performed more than 40 anterior approach procedures at
Banner Good Samaritan since the hospital acquired the surgical table in June
2007.
With its unique capability to position the leg, the PROfx table enables the
surgeon to replace the hip through a single small incision – typically 3-4
inches compared to 10-12 inches in a lateral approach – without detachment of
muscle from the pelvis or femur, and the surgeon can simply work through the
natural interval between the muscle groups. The table allows the surgeon to
position and rotate the hip and leg to aid with the placement of the orthopedic
component – an option not possible with conventional surgical tables. The lack
of disturbance to the lateral and posterior soft tissues provides immediate
stability of the hip after surgery.
"After the replacement the stability of the implant is much better than through
a lateral approach, it's very difficult to dislocate the new joint, and it's
easier for the nurses to care for the patient because there is much less pain
and they are more mobile," Dr. Ott said.
Dr. Ott adds that the anterior approach with the PROfx table provides additional
benefits for the patient, including a muscle-sparing dissection, smaller
incision, reduced blood loss, reduced tissue healing required and a more rapid
return to normal activities.
