Posterolateral Approach to the Hip

Abstract

The modern posterolateral approach to the hip was developed from the posterior approaches described by Kocher and Langenbeck and from subsequent modifications. It is a utilitarian approach to the proximal femur and acetabulum. This approach has a relatively easy learning curve and can be minimally invasive or extensile. There are many indications for the posterolateral approach, and it remains the most common approach for total hip arthroplasty in the United States. With modern techniques and modifications, the dislocation rate associated with this approach rivals that of other common approaches. There is no true internervous or intramuscular plane. To avoid complications, the key vascular and nervous anatomy must be thoroughly understood and respected.
