Per the device evaluation, the following were updated: contact office, phone number, date received by mfr, if follow up, what type?, device evaluated by mfr?, evaluation codes.The warnings in the package insert state this type of event can occur.The broken device was returned for evaluation.According to the evaluation, the complaint that the outer plate of the lactosorb rapid flap clamp detached in situ was confirmed.The most likely underlying cause was determined to be the surgeon did not follow the instructions for use (ifu).According to the evaluation, there are two instructions that were not followed for the possible underlying cause: the first possible underlying cause is due to the surgeon only using 2 lactosorb rapid flap clamps instead of 3 lactosorb rapid flap clamps as stated in the ifu.The ifu states, ¿before replacing the bone flap, position a minimum of three (3) lactosorb rapidflap ls clamps around the craniotomy line in order to achieve optimum stability.Note: the clamps should be placed equidistant from each other around the flap.Therefore, if using three clamps, they should be positioned 120º apart.If using four clamps, they should be positioned 90º apart.¿ the second possible underlying cause is due to not enough post being melted onto the outer plate.The ifu states, ¿flatten the approximate 2mm of post remaining above the upper disc using the contouring tip of the lactosorb heat/contouring pen.Do not heat this device by any other means.¿ there are no indications of a manufacturing defect.
