Abstract

MARRERO RIVERON, Luis O. et al. Value of scintigraphy with Cuban 99mTc-ciprofloxacin in the detection of infected hip prostheses. Rev Cubana Ortop Traumatol [online]. 2006, vol.20, n.1, pp. 0-0. ISSN 1561-3100.

An experimental, analytical cross-sectional study was conducted in 15 patients with suspicion of infectious process that were referred to "Frank País" International Scientific Orthopedic Complex from January 1st, 2003 to December 31st, 2004, aimed at determining the efficacy of the Cuban 99mTc-ciprofloxacin in the evaluation of bacterial infections of the hip prostheses. Bone scintigraphies with 99mTc-methylendiphosphonate and 99mTc-ciprofloxacin were performed at 1, 4 and 24 hours after the injection. The culture/biopsy was used to confirm the criteria. On the visual analysis of the patients, sensitivity was obtained in 100 %, specificity in 75 %, diagnostic accuracy in 93.3 %, positive predictive value in 91.6 %, and negative predictive value in 100 %. The injured/healthy ratio showed significant differences between the patients with and without infection at the diverse hours of acquisition, with a level of significance of a = 0.05. The effectiveness of the Cuban formulation of 99mTc-ciprofloxacin in the evaluation of bacterial infections of the hip prostheses was proved.
