Posterior Approach for MIS with Image-Free Computer-Assisted Navigation

Abstract

This chapter will describe the technique of the posterior mini-incision of average 8 cm length. Sixty percent or more of total hip replacements in the United States are performed through the posterior approach. Therefore, it only makes sense that the majority of surgeons will need to initially learn to perform MIS THR through a posterior approach. Most will not go beyond this approach to an intermuscular one because the posterior mini-incision operation satisfies the needs of most patients. Gait studies have always shown better function post-operatively, at least in the first 6 months, in patients with a posterior rather than an anterior approach [1].
