Diagnosis of orthopedic prostheses infection with 111In-labelled leucocytes

In this study the value of Indium-111 oxinate leukocyte scintigraphy as a diagnostic means in differentiation between septic or non-septic complications after hip surgery has been evaluated. Thirty-two scintigrams were performed in 31 patients, with different types of operations performed and in three different time intervals postoperatively. The overall accuracy obtained was 50%, the specificity 40% and sensitivity 70%. This low diagnostic accuracy seemed mainly to be inherent to the peculiarities of complications observed after arthroplasties. (Auth.)
