Manufacturer Narrative
A device history record (dhr) review was performed for part no. : 03. 037. 010, lot no. : 9872028, manufacturing location: (b)(4), release to warehouse date: 27. Apr. 2016: no non-conformance reports (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. A product investigation was performed. One percutaneous radiolucent insertion handle (03. 037. 112, 9609762) was returned, but had no alleged complaint, and did not exhibit damage which could have contributed to the complaint conditions. No unknown locking screws were returned. The returned parts are included in the trochanteric fixation nail- advanced (tfn-a) system and used for intramedullary fixation of proximal femoral fractures. The returned cannulated connecting screw (03. 037. 010, 9872028) was received with superficial marks near its threading and minor deformations which could have contributed to the complaint condition. Although there was no damage significant enough to make the screw unusable, as a conservative measure the minor damage which was noticed will be used to confirm the complaint condition, and made its replication inapplicable. The returned cannulated connecting screw (03. 037. 010, 9872028) was manufactured on 27apr16 and relevant drawings were reviewed and determined to be suitable for the intended design, application, and dimensional conformity when used and handled as recommended. Review of device history record(s) showed that there were no issues during the manufacture of the product(s), which would contribute to the complaint condition. The material, material properties, and hardness of the returned part(s) were determined to be conforming at the time of manufacture and based on review of the associated/available dhr(s) and based on the details of the complaint and investigation of the returned part(s), additional material/hardness testing is not required. During the investigation no unidentified product design issues or discrepancies were observed that may have contributed to the complaint condition. Based on the available information it is not possible to determine a definitive root cause for the complaint condition. The relevant diameter of the returned screw was measured and found to be within specification. The returned screw was received in decent condition, but it did exhibit minor superficial marks near its threading, and minor deformations which could have contributed to the complaint condition. If the screw was not aligned properly during insertion into a nail, it could have caused the corresponding threads to cross thread, which could have contributed to the complaint condition. 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.

Event Description
It was reported that an original surgery to treat a right femur fracture using trochanteric nail fixation- advanced (tfn-a) was performed on (b)(6) 2017. During the surgery, the surgeon was using a 8. 0 mm hexagonal spherical head screwdriver with a t-handle to loosen the connecting screw in order to disassemble the tfna percutaneous handle from an implanted tfna nail. The spherical head screwdriver did not get a strong grasp of the connecting screw and as it was turned counter clock wise, there was a squealing/screeching and multiple pop sounds produced as the connecting screw threads were rubbing against the nail. The surgeon decided to use a ratchet from a different set and was able to successfully remove the connecting screw which caused a 5-minute surgical delay. Also during the same procedure, as the surgeon was inserting an interlocking screw using a t25 hexagonal stardrive interlocking screwdriver, the tip of the screwdriver disengaged from the screw head multiple times. Surgeon proceeded to successfully complete insertion of the interlocking screw using slight pressure. It was noted at the back table that the tip of the t25 hexagonal stardrive interlocking screwdriver was distorted. The patient was reported to be in stable condition. Concomitant devices reported: percutaneous radiolucent insertion handle (part# 03. 037. 112, lot# 9609762, quantity 1); 10 mm/ 130 degree titanium trochanteric nail fixation- advanced (tfn-a) 360 mm/ right ¿ sterile (part# 04. 037. 056s, lot# h394436, quantity 1). This report is for one (1) cannulated connecting screw. (b)(4).
