Check of the dhr: by checking the dhr of the lot #14aa458, no pre-existing anomaly was detected on 56 smr-reverse resection jigs manufactured.Therefore, all the items were up to specifications.Instrument analysis: the instruments involved in the intra-operative incident (resection jig and pin) were not returned to limacorporate for technical investigation.Picture of the instrument shows the pin jammed into the resection jig.However, based on the provided picture, it is not possible to do any spaculation on the root cause of the event.Based on the few information received, we cannot investigate the root cause of the incident.However, considering that the instrument was 5 years old when the incident occurred and considering the presence of similar complaints on the same instrument code, we can hypothesize that the event was due to a combination of wear due to usage, design factor and surgical factor.Corrective action has already been implemented on family of code 9013.52.304/305.After receiving previous similar complaints, in may 2016 the technical drawing of the smr reverse resection jig was adjusted to slightly increase the holes diameter of the jig and therefore further reduce the intra-operative risk of seizure of the pin into the jig holes.Pms data: according to our pms data and considering the resection jigs code 9013.50.304 and 9013.52.304-305 manufactured prior drawing improvement, (b)(4).Since the new design has been introduced, (b)(4).Both these occurrence rates are overestimated because they do not consider the reuse of the instrument.Most of these issues happened after several uses of the resection jigs or of the pins.None of these cases caused serious consequences on the patient or prolonged surgical time.Limacorporate will continue to monitor the market to promptly detect the possible recurrence of this issue and assess the effectiveness of the corrective action performed.
