    TECH SHOWCASE: Component Positioning in Total Hip Arthroplasty

    Editor’s Note: A session at ICJR’s 13th Annual Winter Hip & Knee Course was billed as a Technology Showcase, featuring 8 presentations on aspects of technology and techniques intended to help surgeons improve outcomes of hip and knee arthroplasty. We are highlighting those presentations on ICJR.net this week.

    In its earliest days, total hip arthroplasty (THA) was performed with the patient in a supine position.

    Joel M. Matta, MD – one of the leaders in the anterior approach to THA in this country – posits that surgeons’ adoption of the posterior approach, which necessitates placing the patient in a lateral position, has contributed to many of the issues with THA today, including dislocation, leg length discrepancy, and inconsistent cup position.

    With that in mind, he told attendees at ICJR’s 13th Annual Winter Hip & Knee Course that his formula for maximum accuracy of component positioning in THA includes:

    • Operating with the patient in the supine position and on a radiolucent table
    • Intraoperatively confirming cup position, leg length, and offset with the C-arm and assistive software

    Click the image above to hear more from Dr. Matta about component positioning in THA, including how he uses intraoperative radiographs to make decisions about leg length and offset.
