The surgeon reported a larger vbr should have been selected.Radiographs were not received.The implant was not returned for evaluation.Review of manufacturing records indicates no non-conformances with respect to material type, material treatments or dimensions.The patient's bone integrity and/or size selection may have contributed to the event.The reported event was not confirmed and no root cause can be determined at this time.Review of labeling notes: potential adverse events and complications: "potential risk identified with the use of this system, which may require additional surgery, include: bending, fracture or loosening of implant component(s), loss fixation, nonunion or delayed union, fracture of the vertebra, implant subsidence".Warnings, cautions and precautions: "correct selection of the implant is extremely important.The potential for success is increased by the selection of the proper size of the implant.While proper selection can minimize risks, the size and shape of human bones present limitations on the size and strength of implants.Metallic and internal fixation devices cannot withstand the activity levels and/or loads equal to those placed on normal, healthy bone.These devices are not designed to withstand the unsupported stress of full weight or load bearing alone.".
