title: Metastasis of lung carcinoma to proximal femur after hip implant.
abstract: Adenocarcinoma of the lung metastasized to the site of hemiarthroplasty for a femoral neck fracture in a 73-year-old woman who had no evidence of preexisting primary or metastatic tumor. The mechanism of the metastasis in this patient remains a question, but it seems likely that metastatic tumor seeding occurred as the result of surgical trauma after the prosthetic implantation.
