Investigation: the check of the manufacturing charts of the lot # involved (#2014aa458) did not show any anomaly on the 56 smr resection jigs manufactured with this lot #.The smr reverse resection jig and pin were returned to limacorporate.Both instruments underwent a dimensional check.It was not possible to extract the pin tip from the jig, therefore it was not possible to measure the diameter of the hole where the pin got stuck.No dimensional anomaly was detected on the pin surface which, however, resulted in having the maximum diameter allowed.This feature, combined with the pin surface, which is worn, may have contributed to the reported malfunction.Two (2) of the seven (7) holes of the resection jig resulted to be slightly under-dimensioned.Nevertheless, a functional check was performed and the pin could pass through all the holes of the resection jig with no difficulty, with the exception of the hole involved where part of the pin is still stuck and the functional test was not possible.In (b)(6) 2016, after becoming aware of similar complaints involving a pin stuck into the resection jig, the technical drawing of the smr reverse resection jig was modified to slightly increase the holes diameter and thus to reduce the risk of recurrence of similar events.Pms data: according to pms data, we are aware of ten (10) similar complaints on a total of 1088 smr reverse resection jigs manufactured before the corrective action described above (product codes #9013.52.302-304-305).In two (2) out of ten (10) cases, pins from other manufacturers were used in combination with limacorporate resection jigs even if limacorporate ifu advise that this must be avoided.No complaints received on the improved version of the instrument.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.Note: this is a final mdr.Please note that the conclusions and the pms data documented here were valid at the time of closure (2016).This final report was created to address the lack of the closing mdr report.
