The Hip: Preservation, Replacement and Revision

Initial Exposure for THR:

    - positioning and prepping   
    - posterolateral skin incision 
    - incise thru iliotibial band 
    - split gluteus maximus 

    - peel back the trochanteric bursa:
          - divide trochanteric bursa and sweep it posteriorly to expose vastus lateralis, short external rotators and posterior border of gluteus medius;
          - this step should be performed carefully so that the surgeon can cleanly dissect the external rotators off their insertion on the greater trochanter;
          - once the bursa has been swept posteriorly, the surgeon will have the proper plane to identify the sciatic nerve, and also the interval between the piriformis and medius;
    - identify the sciatic nerve
    - charnley retractors:
          - insert Charnely retractor at the superior border of the greater trochanter;
          - retract maximus posteriorly & tensor fascia anteriorly;
          - ensure that the Charnely retractor has not been placed directly over the sciatic nerve;
    - elevate minimus off the superior acetabular roof;
          - this is facilitated by inserting a homan retractor underneath the medius and then retracting it anteriorly;
          - subsequently a periosteal elevator is used to elevate the minimus;
    - measure leg lengths:
    - dissect the external rotators and the posterior capsule off proximal femur:
