In 1999, Kocher et al introduced four clinical predictors which were highly predictive (99.6%) of septic arthritis. These included fever (temperature \u2265 38.5\u00b0C), inability to bear weight, white blood-cell count &gt; 12.0 \u00d7 10<jats:sup>9<\/jats:sup> cells\/L and ESR \u2265 40 mm\/hr; CRP \u2265 20 mg\/L was later added as a fifth predictor. We retrospectively evaluated these predictors to differentiate septic arthritis from transient synovitis of the hip in children over a four-year period in a primary referral general hospital. When all five were positive, the predicted probability of septic arthritis in this study was only 59.9%, with fever being the best predictor. When applied to low-prevalence diseases, even highly specific tests yield a high number of false positives and the predictive value is thereby diminished. <\/jats:p><jats:p> Clinical predictors should be applied with caution when assessing a child with an irritable hip, and a high index of suspicion, and close observation of patients at risk should be maintained. <\/jats:p>","DOI":"10.1302\/0301-620x.92b9.24286","type":"journal-article","created":{"date-parts":[[2010,8,26]],"date-time":"2010-08-26T23:28:13Z","timestamp":1282865293000},"page":"1289-1293","source":"Crossref","is-referenced-by-count":96,"title":["Septic arthritis or transient synovitis of the hip in children"],"prefix":"10.1302","volume":"92-B","author":[{"given":"J.","family":"Sultan","sequence":"first","affiliation":[{"name":"Blackpool Victoria Hospital, Whinney Heys Road, Blackpool, Lancashire, FY3 8NR, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.
