It was reported there were two (2) device malfunctions that occurred during a subtrochanteric femur fracture repair using a trochanteric fixation nail advanced (tfna) on (b)(6) 2016.During the reaming process the tip of the reamer (drill bit) broke into two (2) pieces towards in distal end in the patient's femoral neck.It was reported the patient had hard bone in the femoral head and necrosis.The fragment was removed successfully with a 15 minute delay reported in retrieving the fragment.A back up reamer set was available, however, the surgeon decided to use a screw set cannulated reamer to finish reaming the bone.A 2.8mm guide wire was placed in and during the drilling the drill head caught the guide wire and caused the guide wire to break.Approximately 3 cm was left in the bone and was not retrievable.The surgeon then went back to utilize the back-up reamer set and completed the reaming process.A short nail was implanted and the lag screw was able to be implanted.No additional surgical/medical intervention was required.The procedure was completed successfully and the patient is reported to be stable.A combined total of 30 minutes was noted as surgical delay.(b)(4).
