Jj. Dias et al., THE RELIABILITY OF ULTRASONOGRAPHIC ASSESSMENT OF NEONATAL HIPS, Journal of bone and joint surgery. British volume, 75(3), 1993, pp. 479-482
Ultrasound scans were made of the hips of 209 neonates born consecutiv
ely over a two-week period. Of the 418 scans, 62 images were selected
at random and 25 of these were duplicated to give a total of 87 scans.
These static images were then presented to five experienced observers
who each made nine different assessments and measurements. Interobser
ver and intraobserver agreement was calculated and expressed as kappa
values. Our results showed poor reliability on both counts.
