STRYKER V40 HIP RECALL!
Stryker issued a hazard alert for LFIT Anatomic CoCr V40 hips in conjunction with the Therapeutic Goods Administration (TGA), Australia’s equivalent of the U.S. FDA. At the time of this writing, no such action has been taken by the FDA.
The product, manufactured by Stryker Orthopaedics, is actually the femoral head, a part used in total hip replacements. The heads are surgically attached to the top of the femur (the longest bone in the leg) and fit into an acetabular shell, which then fits into the patients’ hip sockets. The hazard alert was issued when Stryker became aware that some of the LFIT Anatomic CoCr V40 femoral heads were more likely to have taper lock failures. The taper lock connects the heads to the femoral neck. The neck is the section connecting the head to the femur.
If the taper lock fails, patients could find themselves, literally, in a world of hurt. The possible results of taper lock failure include:
- loss of mobility
- adverse local tissue reaction
- joint instability
- broken bones around the components
- leg length discrepancy
- need for revision surgery
Currently, Stryker has determined that there are four products with this issue, but included three others that are similar in design just to be safe. The item numbers, head diameters and offsets are listed below:
Specifics to watch for include:
- disassociation of the femoral head from the hip stem
- fractured hip stem trunnion
- increased metallic debris
- insufficient range of movement
- insufficient soft tissue tension
- loss of implant
- bone fixation strength
- increased wear debris (polymetric)
- implant construct with a shortened neck length.
If you are concerned that you may have one of these implants, please contact Frank Rodriguez at (201) 876-8930 or firstname.lastname@example.org.
