Abstract:
OBJECTIVETo detect the clinical value of the ECT bone scan in evaluating of the situation of infection control after hip knee arthroplasty.
METHODSThe clinical data were retrospectively analyzed in 62 patients, including 34 males and 28 females with an average age of 68.8 years old ranging from 65 to 74 years. The results of ECT bone scan, erythrocyte sedimentation rate, C-reactive protein were used to assess periprosthetic infection. The patients with positive ECT and ESR on CRP were considered to have periprosthetic infection; however, the patients with two or more negative, indexes were considered to have no infection.
RESULTSThe sensitivity, specificity, accurate rate of ECT were 75.0%, 88.9%, 87.1% respectively; ESR 50.0%, 72.2%, 69.4%; CRP 62.5%, 81.4%, 79.0%. The combination of the three methods were 87.5%, 96.3% and 95.2%,
CONCLUSIONCompared with ESR and CRP, ECT is a more effective way in the diagnosis of periprosthetic infection, which has great value and is worth popularizing.
