Event Description
Device report from synthes (b)(4) reports an event in (b)(6) as follows: it was reported that a patient underwent a revision procedure to have previously implanted trochanteric fixation nail advanced (tfna) hardware removed. During removal of the implants, one of the 5. 0mm locking screws (bolt) snapped into two (2) pieces. As a result, the far end of the screw fragment remained lodged in the far cortex of the bone, partially engaging the screw hole of the nail. All of the other screws were successfully removed without incident. Then, the surgeon decided to attempt extraction of the nail with the screw fragment still in situ. During this attempt to remove the tfna nail from the medullary canal, however, the screw fragment retained purchase in the patient's bone, causing a fracture in the distal femur. Initially, the plan was to remove the tfna hardware and revise the patient to a total hip replacement. However, this plan was abandoned as a result of the distal femur fracture. The patient was instead plated with a less invasive stabilization system (liss) locking compression distal femur (lcp-df) plating system. The new hardware had to be borrowed from a geographically separate hospital site, which created a ninety (90) minute surgical delay. Additional information pertaining to patient outcome is unknown. The reason for the hardware removal is unknown. This report is for one (1) unknown tfna nail. This report is 2 of 2 for (b)(4).
