Studies Question Advantages of Two-Incision Hip Replacement

Traditional hip replacement surgery is done through an incision that is usually about 5 to 8 inches in length. Some surgeons perform hip replacement through a smaller incision, called a "minimal" incision hip replacement. This incision is about 4 inches in length.

New techniques have been developed that allow the surgeon to perform the same surgery, hip replacement, through two small incisions and with even less muscle dissection. Some people call this a "mini-hip replacement" or a "two-incision hip replacement."

Two studies presented at a late 2007 meeting of the American Association of Hip and Knee Surgeons question if two-incision hip replacement, a new technique, is as good as a minimal incision hip replacement.

Background

Hip replacement is one of the most successful orthopedic procedures in terms of reducing pain and improving function. New techniques are being developed to refine this surgery to further improve the experience for patients. Unfortunately, many "new developments" have not stood the test of time, and many surgeons question if the new two-incision technique is an advantage or disadvantage for patients.
