We have experienced four cases where the distal locking screw of the stryker supracondylar nail (scn) system disengages from the bone and nail.In all four cases the screws have backed out to the point that they were prominent and painful thereby necessitating surgical removal.Patient 1 - left distal femur fracture s/p retrograde intramedullary nailing using stryker scn last year.Prominent screw removal 5 months later.Patient 2 - left distal femur fracture s/p multiple surgeries with retrograde intramedullary nailing of nonunion using stryker scn last year.Prominent screw removal one month later.Patient 3 - right distal femur fracture s/p retrograde intramedullary nailing using stryker scn earlier this year.Prominent screw removal 5 months later.Patient 4 - left distal femur fracture intramedullary nailing using stryker scn earlier this year.Prominent screw removal 4 months later.Manufacturer response for supracondylar nail, stryker supracondylar nail (scn) system (per site reporter).
