Inflammatory Arthritis, Crystal Disease & Systemic Clues
Recognise inflammatory patterns and distinguish them from joint infection and mechanical disease.
Quick revision ↓ Medical Dictionary
01Inflammatory pattern
Prolonged morning stiffness, swelling and a pattern involving several joints can suggest inflammatory arthritis. Ask about skin, eye, bowel and systemic symptoms. The distribution and persistence of synovitis are important; normal inflammatory markers do not automatically exclude clinically significant inflammatory disease.
02Early referral
Persistent synovitis warrants timely rheumatology assessment, particularly when small joints or multiple joints are involved. Do not delay referral solely while awaiting negative or pending blood tests. Early disease-modifying treatment is specialist-led and aims to prevent damage as well as reduce symptoms.
03Crystal arthritis
Gout or calcium pyrophosphate disease can produce an acutely painful swollen joint. Aspiration may help establish the cause and assess infection. A serum urate measurement alone does not establish the diagnosis of every acute attack, and identifying crystals must not end the infection assessment when concern remains.
04Systemic treatment
Anti-inflammatory and disease-modifying treatments have patient-specific risks and monitoring requirements. Review infection risk, organ function, interactions and pregnancy considerations where relevant. Orthopaedic and rheumatology teams should coordinate procedures and medicines rather than abruptly changing long-term therapy without a plan.
05Functional support
Assess hand use, walking, fatigue and participation in daily activities. Physiotherapy, occupational therapy and suitable joint protection can complement medical treatment. New focal severe pain or an acutely hot joint needs reassessment instead of being attributed automatically to an established chronic diagnosis.
High-Yield Revision
- Persistent synovitis can matter despite normal blood markers.
- Do not let tests delay an indicated referral.
- Known arthritis does not explain every new hot joint.
Common Pitfalls
- Diagnosing an acute attack from serum urate alone.
- Changing disease-modifying medicines without coordinated review.
