Dear Marco and Laszlo,
I feel obliged to add some additional considerations. Of course the term "arthritis" denominates acute inflammatory processes of the joint, but these comprise also diseases like rheumatoid arthritis, quite common in dogs and characterized by severe, mostly symmetric deformations of the afflicted joints and definitely discernible in the bare bone. And there are more acute syndroms that cause deformation or even destruction of skeletal/joint elements, like tuberculosis.
Additionally, not every osteogenetic reaction that causes new bone tissue formations must designate a permanent inflammation in terms of an "arthrosis". According to Pauwels' concept of functional adaptation the healthy bone tissue reacts on tensile forces with incremental growth, on loading pressures with involution. So, the theme is even a bit more complex, I suppose.
Best,
Gerhard

Dear Marco,
Thank you for the exact clarification. This is why I reacted in the first place, since arthritis is a term widely used (I may say conventional) in animal palaeopathology for age- or work-related inflammations that are chronic. But differentiation is important.
Best wishes, Laszlo

Dear Patricia,
I would like insert my opinion about your question.
There are many differences between arthritis and arthrosis that both occur in animals. Here I try to explicate this.
The term "arthritis" (or osteoarthritis) refers to a acute pathology present in temporary way and depends on a transitory inflammation. This pathology provokes a reaction in the periostium without new bone tissue formation.
The term "arthrosis" (or osteoarthrosis) refers to a chronic pathology present in definitive way and depends on a permanent inflammation. This provokes an intense reaction in the periostium with new bone tissue formations.
On account of these considerations, we can undoubthably affirm that in zooarchaeological materials there are only cases of osteoarthrosis when we could see osteofitic formations.
In my opinion, in facts, the lesions due to arthritis can not be recognized in ancient bone materials.
Thanks and
Best regards
Marco

Dear ZOOARCHS,
I'm presently working on a project of comparative osteoarthritis in humans and cattle. Being an anthropologist by training, I am a bit lost where to start looking for the pertinent literature on animals. I do have Bartosiewicz et al's seminal monograph on draught cattle but I'm sure there must be loads of veterinary and archaeozoological papers that would prove fruitful in my pursuit. For that reason, I'd be most grateful if some of you could point these out to me.
I would also like to place the following questions to the list:
1-Even though size is not the only factor involved, gravity is definitively an issue to contend with in osteoarthritis, and for this reason I ask you: does anyone know whether osteoarthritis is (or should theoretically be!) more frequent on large mammals or in smaller ones?
2-Any idea about the smallest and biggest mammal species on which osteoarthritis has been thus far reported?
3-In the case of quadrupeds, should one expect more osteoarthritis to occur in the forelimb or the hindlimb?
Thanks a million!
