Retrograde intramedullary supracondylar nails have been added to the orthopedic armamentarium for treatment of distal femoral fractures. Major complications of this new technique have not been noted. We report a case of a femoral fracture at the proximal end of a retrograde intramedullary supracondylar nail. We hypothesize that this complication may be due to the proximal end of the nail acting as a stress riser, with the cortical holes drilled for the interlocking screws compounding this effect.
