For many years we breeders have been assuming that there regularly were differences in observable
hip joint laxity between films made in or near estrus and those made in complete anestrus (not close to a heat cycle).
So, the conclusion of the estrus - laxity question is (again) that true laxity does not hide from the distraction procedure, that it very well might be hidden in the leg - extended view, and that the role of hormones in canine
hip joint laxity (whatever it might be in other species and anatomical locations) is not present, or is immeasurable.

the hip joint laxity characteristic of hip dysplasia or the progression of the degenerative joint changes.

hip joint laxity and joint degeneration, is a multifactorial disease arising from a combination of genetic and environmental factors.

hip joint laxity in dogs with a predisposition to CHD.»
