The Role of Radiostereometric Analysis in the Evaluation of Orthopaedic Implants in the Upper Extremity

Radiostereometric Analysis (RSA) is an accurate method to assess migration of orthopaedic implants. A relation between early migration and long-term implant loosening has been demonstrated in hip and knee arthroplasty. The aim of this thesis was to investigate the potential role of RSA in the upper extremity.
