Growth and remodeling of the hip joint and proximal femur in adolescent dogs. A scintimetric investigation with special reference to hip dysplasia and estradiol induced changes.
The uptake of 85Sr was shown to be higher in dysplastic hip joints than in normal joints of adolescent dogs. This was interpreted as a sign of increased remodeling. In contrast, the uptake of 85Sr in the growth plate and metaphysis of the proximal femur was lower in dogs with hip dysplasia than in dogs with normal hip joints. This was interpreted as a sign of retarded growth of the proximal femur (more advanced skeletal maturation). Greyhounds of bitches, which were injected with estradiol during pregnancy, also showed retarded growth of the proximal femur. This was interpreted as a late effect of estradiol.
