The check of the dhr of the cutting guide involved did not show any anomaly on the 41 cutting jigs manufactured with the same lot # (2015aa037).From additional information, the pin involved is an allegra (competitor) pin.The involved smr reverse resection jig and the pin were returned to limacorporate.The competitor's pin was extracted from the resection jig.By a visual analysis, the pin surface is worn and damaged, probably due to its repeated use; this has probably contributed to the malfunction reported.The jig underwent a dimensional check: no dimensional anomaly was detected on the pin surface and on the diameter of the seven (7) holes of the resection jig; one of the holes has a diameter very close to the minimum allowed, this could have contributed to the malfunction reported.Nevertheless, the analysis performed shows that the device involved was released on the market in compliance to specifications.According to limacorporate post-market surveillance data, a total of six (6) similar complaint were received on a total of 1088 smr reverse resection jig manufactured (model # 9013.52.302-304-305).In two (2) out of six (6) cases, pins from other manufacturers were used in combination with limacorporate resection jigs; limacorporate ifu report that "the components forming original limacorporate systems must be rigorously coupled following the given indications.The use of single components, or components belonging to other systems, are subject to the approval by limacorporate.The manufacturer and the dealer are not liable for possible coupling incompatibility." in may 2016 the technical drawing of the smr reverse resection jig was modified in order to slightly increase the holes diameter and reduce the risk of intra-op seizure of the pin into the holes.The resection jigs involved in all six (6) complaints registered were manufactured before this improvement.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.
