Event Description

Device report from synthes reports an event in (b)(6) as follows: it was reported that the patient underwent an unknown procedure for a diaphyseal fracture on (b)(6) 2019.During the procedure, femoral recon nail and two (2) distal screws were inserted.The nail was back slapped to compress the fracture.Upon proximal lock attempt through the recon locking holes, the drill/wire guides passed through the aiming arm did not align with the holes of the nail, as a result, the guide wires were passed anteriorly to the hole and on a number of attempts, completely anterior to the entire nail.The surgeon had to force the gold tissue protectors posteriorly by hand to find the alignment and proceed with drilling and screw insertion.  a larger than usual lateral thigh incision was required.Initially, it was believed that the problem was caused by the insertion handle/ aiming arm, but it was likely the connection between the insertion handle and the possible flex of the narrow proximal end of the nail that encourages misalignment when the nail is rotated in-situ via the aiming arm.The connection between the insertion handle and the nail remained very strong throughout the procedure - no loosening at all was noted. the instruments in question were still used to complete the procedure, but manual pressure over the wire guides to assist in a posterior direction was required, and the surgery was completed successfully after multiple attempts. there was a surgical delay of 30 minutes.There were no adverse effects expected.  concomitant medical products: unknown outer protection sleeve/ wire guide/ trochar assembly (part# unknown, lot# unknown, quantity# 1).Unknown distal screws (part# unknown, lot# unknown, quantity# 2).This complaint involves six (6) devices.This report is for one (1) unk - nails: femoral.This report is 4 of 6 for (b)(4).
