Table 1 Brief comparative overview of the most important DAA and SuperPATH operation points
DAA | SuperPATH | |
|---|---|---|
Position | supine on a regular operating room table or on a TT | lateral decubitus position on a regular operating room table |
Skin incision | 2–4 cm distal and lateral to the ASIS to a point two finger widths anterior to the greater trochanter | from the tip of the greater trochanter in line with the femoral axis |
Deeper preparation | incision of the fascia over the TFL | incision of the fascia of the gluteus maximus muscle |
Approach to capsule | Muscle-sparing approach to the capsule through the Hueter interval between the TFL and the rectus femoris | muscle-sparing approach to the capsule through the space between the piriformis posterior and the gluteus minimus and medius muscle anterior |
Further steps | • capsulotomy with a flap for later repair • placing acetabular retractors in anterosuperior, anteroinferior and posterior location • osteotomy the femoral neck and femoral head removal • acetabular reaming, cup impaction and implantation of the inlay • broaching proximal femur medullary canal with the reamer and implanting the prosthesis stem • reposition and wound closure | • broaching proximal femur medullary canal with the reamer and implanting the prosthesis stem • osteotomy the femoral neck and femoral head removal • capsulotomy • additional distal small incision for the reamer drive shaft and connecting it with the acetabular basket reamer through the main incision • acetabular reaming, cup impaction and implantation of the inlay • reposition and wound closure |
