MIS Posterior Approach
Minimally Invasive Posterior Approach for Total Hip Replacement
The posterior approach to total hip replacement has been the most commonly done, standard hip approach since the beginning of hip replacement. This approach has undergone significant changes as it has evolved into a minimally invasive approach. In the MIS version, most if not all of the important muscle attachments are left in place (Figure 1), and the incision is down-sized (Figure 2).
Other investigators have corroborated the results of our study. Patients who have MIS posterior approaches have shorter hospital stays, less postoperative pain, shorter rehabilitation, and smaller incisions.
The primary benefits of the mini-incision procedure were derived in the early perioperative period as no significant clinical differences were observed during subsequent follow-up assessments.
