title: Technique to detect migration of femoral components of total hip arthroplasties on conventional radiographs.
abstract: Critical to the evaluation of patients with painful total hip arthroplasties and to the assessment of the efficacy of fixation of new prosthetic designs and/or new insertion techniques is the ability to detect migration of the femoral components. The authors present a simple and effective technique using plain radiography that can detect migration of 1 mm with a high degree of accuracy.
