The direct superior muscle-sparing surgical approach is a total hip arthroplasty surgical technique with proprietary instrumentation, including a tissue-friendly retractor and unique acetabular reamer. This approach is designed for surgeons who prefer the fundamentals and familiarity of the more traditional posterior approach, but want to provide the latest THA muscle-sparing surgical approach techniques for their patients to preserve the iliotibial band, distal external rotators including obturator internus, and abductors.
Direct superior is an iliotibial band and muscle-sparing surgical approach to the hip that offers the potential benefits to the patient of faster recovery,1,2 less pain1,2 and greater satisfaction.3 The direct superior approach and its proprietary instrumentation, including a tissue-friendly retractor and unique acetabular reamer, were designed for surgeons who prefer the fundamentals and familiarity of the more traditional posterior approach, but seek to provide the next evolution in muscle-sparing THA surgical techniques for their patients. This approach was designed to be used with a variety of Stryker’s cementless femoral stem options given the excellent exposure and access to the femoral canal.
The direct superior approach is a true muscle-sparing approach developed to minimize trauma to soft tissue, muscle and tendons that are critical to the functionality of the hip.4 Most noteworthy are the preservation of the iliotibial band, distal external rotators including obturator internus, and abductors. There are potential clinical benefits to the direct superior approach such as enhanced hip stability and postoperative recovery.4,5,6 Additionally, the approach is extensile if necessary, which offers options during surgery in the event of unexpected challenges requiring greater surgical exposure.4 And unlike some other muscle-sparing surgical approaches, the direct superior approach does not require use of a specialized surgical table.
