Final answer:
AC arthropathy is assessed through physical examination, reviewing patient history, and radiographic evaluations such as X-rays, MRI, and arthrography which uses a contrast agent to enhance visualization of soft tissues and detect early cartilage degeneration.
Step-by-step explanation:
Clinically assessing a patient for AC arthropathy involves a thorough physical examination and patient history to evaluate symptoms like joint pain, stiffness, and functional limitation.
Radiographic assessment includes obtaining X-rays to ascertain changes in joint space, osteophytes, and subchondral sclerosis.
MRI (Magnetic Resonance Imaging) and arthrography may also be employed. Arthrography, using a contrast agent opaque to X-rays, can reveal detailed images of soft tissues within the joint, helping to identify early degenerative changes in cartilage before bone changes occur.
