Hip
Resurfacing or Surface Replacement Arthroplasty is
a bone-conserving alternative to conventional Total
Hip Replacement (THR). Unlike THR, hip Resurfacing
does not involve the removal of the femoral head and
neck nor removal of bone from the femur. Rather, the
head, neck and femur bone is preserved in an effort
to facilitate future surgery should it be necessary
and to enable the patient to take advantage of newer
technology or treatments in the future. The current
generation of hip Resurfacing devices utilize a metal
bearings have demonstrated a much higher level of
wear resistance as well as reduced bone loss and inflammatory
tissue reaction about the hip joint as compared to
metal-polyethylene bearings.
Hip Resurfacing is anatomically and biomechanically
more similar to the natural hip joint resulting in
increased stability, flexibility and range of motion.
Further, dislocation risk is virtually eliminated.
Higher activity levels are typically achieved with
less risk. These benefits are realized because the
head diameter that results from Resurfacing is very
similar to the patient's normal head diameter and
these larger head sizes are typically much larger
than the femoral balls utilized in conventional THR.
