CPPD DEPOSITION DISEASE

From NeuroRehab.wiki

SUMMARY

1. Most idiopathic CPPD deposition occurs in patients > 65 years of age and who have underlying joint damage from OA or trauma.

2. When in a patient < 50 years of age, consider: primary hyperparathyroidism, hypomagnesemia, hypophosphatemia, haemochromatosis, hypothyroidism.

3. Presentation ranges from asymptomatic deposition to pseudogout.

4. Chondrocalcinosis is calcification of cartilaginous tissue and is a hint to underlying CPPD.

5. CPPD arthropathy usually affects the knee. Others include wrists, 2nd& 3rd MCPJ, shoulders, elbows, and ankles.

6. Look out for the patient with wrist arthritis with Bouchard (PIP) and Heberden (DIP) nodes: screen for hemochromatosis, hyperparathyroidism, and hypothyroidism in patients < 50 years.
