Abstract

The effectiveness of ultrasound in depicting the normal anatomy of the coxofemoral joint in puppies was evaluated. Ultrasound images were obtained from twenty Springer Spaniel puppies ranging from one day to twelve weeks of age. The anatomy of the hip joint could be identified up to eight weeks of age. By twelve weeks of age the degree of ossification prevented complete hip joint evaluation. Three different views were utilized. The longitudinal and dorsolateral views were the most useful. Motion of the femoral head within the acetabulum could be observed. Measurements of the acetabulum, femoral head and joint space could be obtained however these measurements were inconsistent. The technique appears to be useful for depicting the anatomy of the neonatal coxofemoral joint however, additional studies utilizing both normal and dysplastic puppies are recommended to determine if this examination will be useful in discriminating between normal and dysplastic puppies.
