Manufacturer Narrative

Visual inspection performed by r&d project manager on 20 september 2018 the dual-mobility pe liner shows important material erosion with respect to the original shape.The pe loss seems due to third body wear or to repeated contact and friction with abnormal third body.Few light shining debris are visible inside the scratches in the pe liner, when exposed to bright light.Microscopic analysis reveals black particles on the pe liner outer surface.It might be assumed that these are metal debris.No other debris of other nature were found on the liner.Femoral head shows few metal-transfer signs and huge metal-transfer area.It is not possible to determine failure root cause.At the time of revision surgeon reports no metallosis in the patient and a perfect status of shell and stem.
