Manufacturer Narrative

Additional narrative: the complaint states during implanting the attune tibial component with the attune tibia rp impactor, the impactor broke down to two pieces.The investigation confirmed that the impactor had broken as reported.Expert opinion indicates that the failures are associated with environmental stress cracking (esc).The attune rp tibial impactor has been annealed to reduce residual stresses.Lab tests indicate significant reduction in residual stresses of annealed samples in comparison to un-annealed samples however a complete reduction in stresses is not achievable.This device is from an annealed batch.A field safety notice was issued in nov 2014 stating to reduce the possibility of leaving fragments in patients, the company suggests adhering to the instructions for use (ifu), which include inspecting the impactor¿s to ensure that no instruments or pieces of instruments are left in the surgical site prior to closure.It should be noted that capa-(b)(4) has been initiated and can be referenced for further details.The complaint shall be closed with a justified conclusion; it will be entered into the complaint database and monitored through trend analysis.
