Event Description

It was reported that on (b)(6) 2018, anterior lumbar interbody fusion (alif) was performed at l4-s1 with synthes synfix evolution.There were difficulties placing one of the s1 screws on the l5-s1 level.After inserting the spacer at l5-s1, the awl was placed through the aiming device to cannulate s1.It was very difficult to fully advance the awl into the "sclerotic" bone that the patient had at s1.The awl appeared to be 15mm in length but the screws being used were 25mm.This left 10mm of bone not prepped for a screw.This was confirmed by viewing the ct scan on the imaging in the room - the bone was dense and sclerotic.After advancing the awl by malleting and twisting, a fine tip screw was placed into the hole of s1.After advancing the screw about 2/3 of the way through that plate on the spacer, the screw would not advance anymore.The screw was taken out.The surgeon wanted to drill into recannulated hole deeper into s1 so he could allow the screw to advance.With no drill option, the aiming device was elected to be taken off and the awl "freehand" was used which is not suggested in the technique guide.The screw was placed without the aiming device attached to the spacer.Using the standard screwdriver, the surgeon could only get the screw to advance about 2/3 of the way through the plate.Then, the straight screwdriver was used to get more axial pressure to advance the screw.And surgeon had to mallet occasionally to get the screw to advance, which ended up getting the screw to advance and lock into the plate.There were no issues with the remaining screws advancing using the awl through the aiming device.The procedure was completed successfully.There was a surgical delay of 10 minutes.Patient status is unknown.This complaint is for one (1) synfix® evolution fine tip screw/25mm - sterile.Concomitant device reported: unknown plate (part # unknown, lot # unknown, quantity 1).This complaint involves three (3) devices.This report is 2 of 3 for (b)(4).
