Reason/Issue |
Stryker has identified a non-conformance due to a trend analysis showing an incidence of taper lock failures higher than the predicted rate (>0.05%) for four LFIT Anatomic CoCr V40 Femoral Heads manufactured prior to 2011. The increased incidence of taper lock failures relates to possible taper lock interface inconsistency. Potential hazards include disassociation of femoral head from hip stem, fractured hip stem trunnion, increased metallic debris, insufficient range of motion, insufficient soft tissue tension, noise, loss of implant, bone fixation strength, increased wear debris (polymeric), implant construct with a shortened neck length. |
