A new method of dynamic ultrasonographic evaluation of passive coxofemoral joint laxity was used to examine a total of 30 greyhound (n = 13) and nongreyhound (n = 17) puppies. Puppies were evaluated sonographically at four, six, eight, 12, 16, and 26 weeks of age. The coxofemoral joints were distracted manually, and the femoral head displacements were measured during distraction. The greyhounds had significantly smaller (p less than 0.01) maximum distraction distance (mean +/- standard deviation [SD], 0.11 +/- 0.04 cm) than nongreyhound puppies (mean +/- SD, 0.26 +/- 0.10 cm). In six- to eight-week-old puppies, the maximum distraction distance was correlated significantly (p of 0.0001, adjusted correlation coefficient [r2] of 0.27) with stress radiographic indices. Coxofemoral joints interpreted as being abnormal on hip-extended radiographs taken at one year of age were associated significantly (p of 0.0001) with higher maximum distraction distances in six- to eight-week-old puppies.
一种用于动态超声评估被动性股髋关节松弛度的新方法，被用于检查总共30只灵缇犬（n = 13）和非灵缇犬（n = 17）幼犬。在幼犬4周、6周、8周、12周、16周和26周龄时对其进行超声检查。手动牵开股髋关节，并在牵开过程中测量股骨头位移。灵缇犬的最大牵开距离（均值±标准差[SD]，0.11±0.04 cm）显著小于非灵缇犬幼犬（均值±SD，0.26±0.10 cm）（p < 0.01）。在6至8周龄的幼犬中，最大牵开距离与应力放射学指标显著相关（p = 0.0001，调整相关系数[r2] = 0.27）。在1岁时拍摄的髋关节伸展位X线片上被判定为异常的股髋关节，与6至8周龄幼犬更高的最大牵开距离显著相关（p = 0.0001）。
