The
Minimally Invasive Total Hip replacement was developed to minimize patient
morbidity and shorten recovery time. This technique is not a "small
incision-large dissection" technique like some other minimally invasive
techniques (commonly referred to as "mobile window" techniques).
The deep dissection with this technique extends no further than the length
of the incision. This minimally invasive technique differs from the traditional total hip replacement procedure not only due to an incision 2/5 the traditional length, but also due to less deep dissection. The gluteus maximus tendon is not released. Only 4 of the 6 external rotators are detached; the piriformis and quadratus femoris tendons are left intact. The anterior and superior capsules are left intact, and the posterior capsule is retained for anatomic repair at the end of the case. The development of new instrumentation and better surgical technique provides excellent visualization, minimal skin retraction problems, and accurate component placement. To date surgeons have performed over 3,000 minimal incision procedures and have found the technique to be accurate, reproducible, and advantageous to both patient and surgeon. This technique can be used with cemented or cementless fixation. |
