The 1-2 punch
for Well Fixed Stems
The Watson Extraction System (WES) is a surgical tool designed to facilitate the removal of well-fixed femoral stems during revision hip arthroplasty (hip replacement surgery), by using a 3D osteotome that closely matches the shape of the implanted stem, effectively cutting around it to disrupt the bone-implant interface and allow for easier extraction; essentially, it helps remove a previously implanted hip stem with minimal bone damage during revision surgery.
Key points about the Watson Extraction System®
Function
It acts like a specialized surgical chisel that precisely fits around the femoral stem, allowing for a circumferential cut to separate the bone from the implant.
Benefit
By mimicking the stem's geometry, the WES minimizes the need for extensive bone removal during stem extraction, potentially preserving more bone stock for the revision implant.
Application
Primarily used in revision hip surgeries where a well-fixed femoral stem needs to be removed.
