The pelvic distraction-stress radiographs of 50 clinically normal Korean Jindo which confirmed to have non-dysplastic hip joints on the ventrodorsal extension view, were investigated to evaluate the passive coxofemoral joint laxity as quantified by the distraction index. The synovial fluid cavitation of the unilateral coxofemoral joint was detected in 8 dogs, and distraction index was not measured in theses cavitated joints. The distraction index measured minimally 0.20, and maximally 0.74. The medial distraction index for the dog examined was 0.42, and 75th percentile distraction index was below 0.50.
