Traditional hip replacement surgery, in practice since the 1960s in the United States,
has typically utilized an extensive, five- to 10- inch curved incision on the side
of the hip, extending into the buttock area. The deep portion of the dissection
divides a number of important stabilizing muscles and tendons and ends with removal
of the dense fibrous capsule of the hip joint. The actual size of the incision depends
on the size of the patient. Although this approach affords wide exposure to the
posterior half of the hip joint, it also leads to a predictably large blood loss
and significant rehabilitation time. |

A handful of hip replacement specialists in this country have developed specialized
techniques and instruments to allow the same operation to be done with a very limited
incision and dissection. The skin incision is typically two to three inches in length.
Direct visualization of the hip joint is still possible, because of special lighting
instruments and retractors. The deep structures, including the capsule, are repaired
after the prostheses have been implanted. There should be a heading put in saying
"Minimally invasive surgery (MIS) hip replacement. the heading should appear after
the 9th point.

The advantages of this approach are many, including reduced operative time, decreased
blood loss, fewer postoperative dislocations, reduced pain, and a faster recovery
for the patient. The length of stay in the hospital has also been reduced to approximately
two days. These improvements have also made hip replacement surgery available to
many patients with health problems severe enough to preclude the traditional procedure.
