    THIS FOLLOW-UP REPORT IS BEING SUBMITTED TO RELAY ADDITIONAL INFORMATION. NO PRODUCT WAS RETURNED, OR PICTURES PROVIDED; VISUAL AND DIMENSIONAL EVALUATIONS COULD NOT BE PERFORMED. A REVIEW OF THE DEVICE MANUFACTURING RECORDS CONFIRMED NO ABNORMALITIES OR DEVIATIONS THAT COULD BE RELATED TO THE REPORTED EVENT. DEVICES ARE USED FOR TREATMENT. THE REPORTED PRODUCTS WERE REVIEWED FOR COMPATIBILITY WITH NO ISSUES NOTED. SURGICAL TECHNIQUE SAP: REVIEW SURGICAL TECHNIQUE: THE CORRECT IMPLANTATION AND INSERTION (TLS PLACEMENT AND SET SCREW LOCKING) IS DESCRIBED IN THE SURGICAL TECHNIQUE. PLEASE ALSO NOTE THE FOLLOWING SECTION REGARDING "SET SCREW LOCKING": AFTER THE TLS IS PLACED, THE PRE-ASSEMBLED SETSCREW IN THE NAIL MUST BE TIGHTENED WITH THE TORQUE LIMITING HANDLE OFFERED WITH THE SYSTEM, TO PREVENT THE TLS SLEEVE FROM MOVING POST-OPERATIVELY. AN ANTERIOR SUPPORT SCREW CAN BE PLACED IN ADDITION TO THE TLS TO PROVIDE ROTATIONAL STABILITY AND SUPPORT THE TREATMENT OF UNSTABLE INTERTROCHANTERIC FRACTURES WITH LARGE POSTEROMEDIAL (LESSER TROCHANTER) AND POSTEROLATERAL (GREATER TROCHANTER) FRAGMENTS, PREVENTING EXCESSIVE LAG SCREW SLIDING POST-OPERATION. REVIEW OF COMPLAINT HISTORIES FOUND NO ADDITIONAL RELATED ISSUES FOR THESE ITEMS AND THE REPORTED PART AND LOT COMBINATIONS. SEVERAL X-RAYS WERE RECEIVED AND REVIEWED BY A RADIOLOGIST.

SURGICAL REPORTS WERE NOT PROVIDED. BASED ON THE AVAILABLE INFORMATION, IT IS NOT POSSIBLE TO DETERMINE THE ROOT CAUSE FOR THIS ISSUE. A FURTHER AND MORE COMPREHENSIVE INVESTIGATION WAS CARRIED OUT AS PART OF A CA, WHICH DETERMINED THAT NO POTENTIAL CORRECTIVE AND/OR PREVENTIVE ACTIONS ARE REQUIRED.
