Posterolateral Approach
摘要
Given the extensive exposure often required in revision total hip arthroplasty, the surgical approach selected should allow flexibility for extension of exposure as needed. The posterolateral approach provides excellent exposure for most acetabular and/or femoral revisions and easy conversion to more extensile approaches. Decreased time of surgery, excellent exposure with minimal muscle damage, and fast rehabilitation make this approach attractive for most revisions in the appropriate patient. Similarly, the direct superior approach, a modification to the posterior approach to the hip, is extensile, soft tissue preserving, and provides exceptional stability. With the direct superior, the piriformis insertion is maintained, the iliotibial band is preserved, and the capsule is repaired in an anatomic side-to-side fashion. This approach can be applied in the revision setting if soft tissues allow, with the benefits of a faster recovery, less operative cost, improved stability of the hip, and better pain and function postoperatively.
