On an x-ray, what would you see in a patient with neurotrophic arthropathy?
|
In weight bearing joints:
- hypertrophic changes ---the 6D's ---Distension ---Density(subchondral) ---Debris ---Dislocation ---Destruction ---Disorganization In non weight bearing joints (upper extremities): - atrophic changes |
