A visual assessment of the returned complaint rongeur showed an instrument with repeated use, as identified by worn laser markings and surface scratches.The two actuating rails of the instrument had wear marks present from use, and the distal cutting surfaces were bent out of alignment.The top cutting surface bent laterally approximately 30°.A functionality assessment was not performed due to the damaged condition of the returned system rongeur, which was removed from distributable inventory.A dhr review was performed for the complaint device lot and there were no manufacturing anomalies identified.The device lot met all required specifications prior to being released to distributable inventory.This lot has been available for distribution since 2/03/2016.A system rongeur may be bent when clamped on a portion of bone if there was excessive force applied to the instrument handle.It may also be possible that the rongeur could be bent when clamped on a portion of bone if the instrument handle was rotated while engaged with patient bone.There have not been any other complaints of similar nature in the past 12 months.The manufacturer will continue to monitor this instrument for complaints from the field.
