Anterior Approaches in Hip Surgery

The Smith-Petersen anterior approach and the Watson-Jones anterolateral approach are the two most renowned anterior approaches for hip surgery. The anterior approach offers several advantages, including a reduced dislocation risk as compared with that associated with the posterior approach. The post-operative dislocation rate after total hip arthroplasty is known to be 2~3 times lower than that of the posterior approach. However, a more extensive skin incision and poor anatomical visualization are some of the disadvantages of the anterior approach. Nevertheless, since this approach preserves the circulation to the femoral head, the ability to perform the anterior approach is imperative for hip surgeons.
