Manufacturer Narrative

The complaint states attune tibial and femoral impactors fractured.The investigation confirmed that the impactors had fractured.Expert opinion indicates that the failures are associated with environmental stress cracking (esc).The attune impactors have 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.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 (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.
