Event Description

It was reported that during the plating portion of an orif proximal tibia procedure on (b)(6) 2018 the surgeon was having trouble connecting neutral guide to the aiming arm.After attempting several common troubleshooting techniques to try solving the connecting issue, the scrub tech noticed that the neutral guides were bent, causing them not to function properly.This connecting issue between the devices caused an estimated surgical delay of 10 minutes and caused the surgeon to have to make more incisions than originally intended.These additional incisions were needed to locate the exact placement of the screw holes, because the aiming arm was unable to be used.The sizes of the incisions were longer in length than the original ones created.The surgery was successfully completed using one of the damaged guides that appeared still functional.The patient outcome was reported as fine following the procedure.Concomitant devices reported: plate (part number unknown, lot number unknown, quantity 1).This report is for one (1) locking/neutral guide for 3.5mm va lcp proximal tibia aiming arm.This is report 1 of 3 for (b)(4).

Manufacturer Narrative

Dhr review was completed.Part no.: 03.127.010 lot no.: 8251050 manufacturing location: (b)(4) release to warehouse date: 19.Apr.2013 no ncrs were generated during production.Review of the device history record(s) showed that there were no issues during the manufacture of the product that would contribute to this complaint condition.Customer quality conducted an investigation of the returned devices.Three locking/neutral guides were returned with part # 03.127.010 and lot # 8251050.The distal ends of the devices were all found to be bent/deformed.The tabs on one of the devices appeared to be visually deformed, therefore the distance between the tabs was measured for all three devices.The devices measured 21.08mm, 22.14mm and 23.50mm.Measured using mitutoyo caliper.The first two devices were within specification; however, the third was not within the specification of 21.4mm +/- 1.0 per drawing.The third device was the one which visually exhibited deformation.The complaint was confirmed.The drawings were reviewed during investigation replication of the complaint condition is not possible as the aiming arm was not returned.Based on review of the dhr records there is no indication that any issues with material or material properties contributed to the complaint condition.No definitive root cause could be determined.It is likely that the devices experienced rough handling over 4+ years of use.There were no issues during the manufacture of this product that would contribute to this complaint condition.During the investigation, no product design issues or discrepancies were observed that may have contributed to the complaint condition.Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed.Based on the contents of the associated dcrm the complaint condition is adequately addressed and the calculated occurrence rate does not exceed established limits.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
