Plain-English summary
A group of eight-month-old Labrador retrievers underwent different tests to check for hip dysplasia, a common joint problem in dogs. The researchers compared two distraction techniques and a standard hip score method to see which was best at predicting hip issues by the time the dogs turned one year old. The PennHip method was found to be the most accurate, correctly identifying all dogs without hip dysplasia, while the other methods were also useful but less reliable. This study suggests that using the FCI hip score is the best way to assess hip health in young dogs.

Abstract
Two radiographic distraction techniques (one employing a wooden lath and, the other, a PennHip distractor), an ultrasonographic distraction method and conventional radiographic Fédération Cynologique Internationale (FCI) hip score were evaluated in eight‐month‐old Labrador retrievers to determine the most reliable method for predicting radiographic FCI hip score at the age of one year. With reference to the FCI hip score, sensitivity and specificity of the PennHip method were 100 per cent and 54 per cent; sensitivity and specificity of the lath technique were 85 per cent and 71 per cent; whereas they were 62 per cent and 67 per cent for the ultrasonographic method. For all distraction methods, the positive predictive value (PPV) was moderate and the negative predictive value (NPV) was high. Sensitivity, specificity, PPV and NPV were 100 per cent for the FCI hip score. It is concluded that, at the age of eight months, FCI hip score is the most reliable method for predicting FCI hip score at the age of one year in the colony of dogs investigated. Both the PennHip and lath method were also clinically reliable techniques in predicting true negatives. The ultrasonographic distraction method was moderately reliable.
