Pseudogout Etiology / Epidemiology / Natural History
- Caused by calcium pyrophosphate deposition in joints.
- May lead to scapholunate advanced collapse in the wrist.
- Chondrocalcinosis = calcification of the articular cartilage or meniscus. Usually occurs in the periphery. More common in women. Incidence increases with age.
- May affect any joint: 50% occurs in the knees. Generally occurs in larger joints. sternoclavicular joints etc.
Pseudogout Clinical Evaluation
- Acute severe pain in a single joint without antecedent trauma.
- Pain, warmth, tenderness, erythema of affected joint.
Pseudogout Xray / Diagnositc Tests
- Xrays: demonstrate chondrocalcinosis of the menisci or articular cartilage.
- Joint aspiration: Fluid sent for cell count, gram stain and cultures. Calcium pyrophosphate crystals are weakly positive birefringent rhomboid-shaped crystals.
Pseudogout Classification / Treatment
- Consider NSAIDs and corticosteroid injections.
- Exercise, weight loss and canes may be beneficial
Pseudogout Associated Injuries / Differential Diagnosis
- Associated with: hyperparathyroidism, hemochromatosis, hypophosphatasia and hypothyroidism
- Rheumatoid arthritis
- Charcot arthropathy
- Septic Joint
- Lyme disease
- Generally managed by PCP/rheumatologist long-term.
