I am not POSITIVE, but D definitely makes the most sense to me!

Looks like D to me as well. The degeneration of the articular cartiledge would make ROM difficult for sure. Hope you look it up to be correct. You can google it as well.

D. I would goback to anatomy/physiology book to look for rationale

D. People who has osteoarthritis starts to lose ROM because the loss of cartilage.

Osteoarthritis is also known as DJD...Degenerative Joint Disease. That should lead you in the right direction. :)

I'm working on a case study based on a patient with osteoporosis. I have all the questions answered except one. I've looked in 3 of my text books and used the internet to search but I have yet to find an answer. If anyone can help I would really appreciate it. I have found causes but nothing that says what the primary one is. The question is:

The primary cause of limited range of motion in a joint afflicted with osteoarthritis is/are:

a.Bone spurs

b.Loss of proprioceptive reflexes

c.Formation of new bone

d.Degeneration of articular cartilage

e.Cysts that form in subchondral bone

If anyone could explain what is the primary cause I'd appreciate it. I think it's degeneration of articular cartilage but considering this is a big part of my grade I want to be POSITIVE.

Which one are you focusing on? Very different diagnoses :)
