VerSys® Hip System Porous Hip Prostheses
For physicians who favor a porous philosophy for implanting hip prostheses
without bone cement, Zimmer offers several options, each designed to help the
surgeon achieve appropriate joint stability. In this approach, a rasp is used
to create the shape of the implant within the femoral canal. The rasped shape
is slightly smaller than the implant itself. When the implant is inserted, a
"press-fit" is achieved. The porous surface allows natural bone then to grow
into the implant to provide secure fixation. Fiber metal mesh or beads are two
porous surface options that are strategically placed on the implant to allow
for fixation at key areas-top, mid-stem, or overall fixation.
The VerSys MidCoat Hip implants, with fiber metal mesh or beads, provide
fixation at the top of the prosthesis and use cutting splines for rotational
stability at the bottom. The VerSys FullCoat Plus implants, with beads,
provide fixation from top to bottom. The physician (with the patient) will
decide whether overall fixation or fixation at the top of the hip prosthesis
is appropriate for each patient's individual situation.
