Dear Eve, dear All, My first impression was a nicely healed but dislocated greenstick fracture based on the rather acute angle in the bone. Modern Dachshunds represent an extreme curvatures of limb bones (esp. in the zygopodia) due to inherited chondrodysplasia (fibroblast growth factor fgf4). But even those look milder. The femur is actually very stout and basically straight. See this picture: https://zooarchaeology.ning.com/photo/dachshund?context=user [https://api.ning.com/icons/appatar/3457517?default=3457517&width=90&height=90]<https://zooarchaeology.ning.com/photo/dachshund?context=user> ZooBook<https://zooarchaeology.ning.com/photo/dachshund?context=user> zooarchaeology.ning.com A network for zooarchaeologists to share information I agree that metabolic conditions such as rickets, would also produce relatively mild curvatures, unless the bone reaches a critical point and "collapses" into an angle as shown in the original photo/x-ray. But I am not aware of such clinical cases. More ideas are welcome.

I've seen (much) milder degrees of bowing while this seems to be an extreme case (if it is that). Cheers, Angelos H.

"Among the material was the right femur of a dog which had a conspicuous dished bend towards the front of the bone. Because of the extreme curve it was thought it to be the result of a pathological transformation, maybe a healed fracture. But we couldn't identify any traces of a bone fracture. I had a vet take a look at the bone, who even radiographed it but also couldn't find any signs for a pathological alteration." I've uploaded the two pictures here in Google Drive<https://drive.google.com/drive/folders/1_LpM04c6QA1NDzgmn9UNt-4dmGpP7pnk?usp=sharing>. Please let me know if you think of any reason for this anomaly, so I could forward this discussion to Stefan. Thank you!
