Where to Send a Patient with Hand Pain and Swelling
Start with plain radiographs (X-rays) of the affected hand/wrist at your local facility, and refer to a hand surgeon or orthopedic specialist for clinical evaluation if imaging is abnormal, symptoms persist, or there are concerning features on physical examination. 1
Initial Evaluation Approach
The ACR Appropriateness Criteria clearly establishes that radiography is the first-line imaging study for chronic hand or wrist pain 1. Standard radiographic evaluation includes three views (posteroanterior, lateral, and oblique) which can assess:
- Joint alignment and ulnar variance
- Joint space narrowing
- Fractures (acute, chronic, or nonunited)
- Erosions and arthritis patterns
- Soft tissue swelling and mineralization
- Impaction syndromes and static instability
In many cases, radiographs alone establish the diagnosis or confirm clinical suspicion, making them sufficient for initial workup 1.
When to Refer to a Specialist
Refer to a hand surgeon or orthopedic hand specialist when:
- Radiographs show fractures, dislocations, or significant arthritis requiring surgical evaluation
- Clinical examination suggests tendon injury, nerve compression, or ligamentous instability
- Suspected infection (flexor tenosynovitis, abscess, septic arthritis) requiring urgent surgical consultation
- Persistent symptoms despite normal radiographs warrant advanced imaging (MRI or ultrasound) and specialist assessment
- Acute trauma with significant mechanism of injury
Setting of Care
Most hand pain and swelling can be initially evaluated in:
- Primary care offices
- Urgent care centers
- Emergency departments with basic radiographic capability
Research demonstrates that 66% of transfers to tertiary trauma centers for hand injuries are inappropriate 2, with many cases manageable at regional hospitals. Inappropriate transfers are more common during off-hours and in underinsured patients 2. This suggests that initial evaluation and basic management should occur locally, with telephonic consultation to hand surgeons when needed 3.
Advanced Imaging Considerations
If radiographs are normal but symptoms persist, ultrasound or MRI without contrast are the next appropriate studies 1:
- Ultrasound is particularly useful for superficial structures (tendons, ligaments, nerves) and allows dynamic assessment and contralateral comparison
- MRI without contrast provides comprehensive soft tissue evaluation including ligaments, cartilage, and occult fractures
- Point-of-care ultrasound in the ED can expedite diagnosis of infections, leading to earlier antibiotics and consultation 4
Common Pitfalls to Avoid
- Do not order CT, bone scans, or contrast-enhanced studies as initial imaging - there is no evidence supporting these as first-line tests 1
- Do not transfer all hand injuries to tertiary centers - establish local protocols with hand surgeon consultation to avoid unnecessary transfers 2, 3
- Do not delay evaluation of suspected infections - flexor tenosynovitis and deep space infections require urgent hand surgery consultation
Special Considerations for Inflammatory Arthritis
If inflammatory arthritis is suspected (symmetric joint involvement, morning stiffness, systemic symptoms), radiographs remain the initial study, but ultrasound or MRI with gadolinium may be needed to detect early synovitis and erosions 5. These patients should be referred to rheumatology in addition to or instead of hand surgery.
