> the complaint states: ¿at the moment of the placement of biostop plug number 12 after having correctly prepared the medullary canal, the surgeon introduces the cap with the corresponding setter.It is caught in the canal, but in an attempt by the surgeon to remove the plug from the cap, it decapitated.When this situation occurred, another biostop number 14 plug was opened, since the previous one had broken, but when placing this new implant, the same issue happened.¿ the hospital has supplied photographs to aid investigation of this complaint (see attachment ¿(b)(4) photos.Pdf¿).The top ¿fin¿ has separated from the rest of the unit.The photographs confirm the complaint description.The complaint description states that 2 different sizes of restrictor (customer describes as ¿plug¿) were used, and this indicates that the sizing trial step may not have been completed correctly.Biostop restrictors are made to take compression load, but from the information available, it appears that when the surgeon was attempting to retract the introducer rod and restrictor holder (customer describes as ¿cap¿), torsional stress was applied and caused the biostop restrictor to break.The ifu for both the restrictor and the instrumentation set advise that they are designed for use with hand pressure only, and that excessive torsional stress should be avoided (see attachment ¿(b)(4) ¿ en ifu extracts.Pdf¿).Based on the information available, the root cause for this complaint is user error.No information received with this individual complaint indicated that a broader investigation or corrective action was necessary the number of complaints received for this failure mode will continue to be monitored and product updates/ recommendations will be implemented at the post market surveillance review dependent upon occurrence ratings.Depuy synthes considers the investigation closed at this time.Should additional information be received, the information will be reviewed and the investigation may be re-opened as required.Device history lot
