Initial Evaluation and Management of Wrist Pain
Begin with plain radiographs (posterior-anterior, lateral, and oblique views) as the first-line imaging study for any patient presenting with wrist pain, as this establishes a specific diagnosis in the majority of cases and guides all subsequent management decisions. 1, 2
Clinical History - Key Elements to Elicit
A detailed history alone leads to a specific diagnosis in approximately 70% of wrist pain cases 3:
- Mechanism of injury: Spontaneous onset, distant trauma history, or repetitive loading activities suggest carpal bone nonunion or avascular necrosis 3
- Pain location: Radial-sided (De Quervain tenosynovitis), ulnar-sided (distal radioulnar joint subluxation, TFCC injury), or central (ganglion cysts, Kienböck disease) 2
- Pain pattern: Worsening with movement suggests mechanical pathology; rest pain suggests inflammatory or infectious etiology 2
- Associated symptoms: Numbness suggests nerve compression (carpal tunnel syndrome); swelling suggests inflammatory arthritis or infection 2, 4
Physical Examination - Specific Maneuvers
Palpate systematically to localize tenderness to specific anatomic structures 3:
- Finkelstein's test: De Quervain tenosynovitis 3
- Scaphoid tubercle tenderness: Scaphoid fracture or nonunion 3
- Lunotriquetral shear test: TFCC or lunotriquetral ligament injury 3
- Watson's test (scaphoid shift): Scapholunate ligament instability 3
- Grind test: First carpometacarpal arthritis 3
Initial Imaging Algorithm
Standard Radiographs (Always First)
Obtain posterior-anterior and lateral views in neutral position, supplemented by oblique views 1, 2:
- Lateral view demonstrates malalignments and soft-tissue swelling 2
- Stress positions can elicit dynamic instability not visible on standard views 2
- Radiographs identify fractures, arthritis, bone tumors, impaction syndromes, and static wrist instability 2
When Radiographs Are Normal or Equivocal
MRI without IV contrast is the next appropriate study for persistent symptoms with unclear diagnosis 1, 2:
- MRI accurately depicts bones, bone marrow, articular cartilage, ligaments, TFCC, synovium, tendons, and neurovascular structures 2, 4
- For radial-sided pain: MRI without IV contrast 1
- For ulnar-sided pain: Either MRI without IV contrast or MR arthrogram 1
- For suspected occult fractures or stress fractures: Either MRI or CT without contrast 1
Location-Specific Advanced Imaging
Ultrasound is preferred for extra-articular pathology 2, 5:
- Ganglion cysts: Ultrasound confirms fluid-filled nature with accuracy similar to MRI 5
- Tendon pathology: Ultrasound effectively diagnoses flexor and extensor tendon abnormalities 2
- Carpal tunnel syndrome: Ultrasound measures median nerve cross-sectional area 2, 4
CT scanning is preferred for distal radioulnar joint subluxation, obtaining images of both wrists in supination and pronation 2
When to Suspect Inflammatory Arthritis
Order MRI with or without IV contrast if inflammatory arthritis is suspected and guidance for management is needed 1:
- MRI with contrast identifies active synovitis, inflammatory tenosynovitis, and bone marrow edema (osteitis) 2
- Bone marrow edema on MRI is the best predictor of future rheumatoid arthritis progression 2
Obtain laboratory testing when inflammatory conditions are suspected 2:
- ESR and CRP for diagnosis and prognosis of undifferentiated peripheral inflammatory arthritis 2
- Rheumatoid Factor (RF) and Anti-Citrullinated Protein Antibodies (ACPA) are predictive of rheumatoid arthritis 2
- ANA testing if connective tissue disease is suspected 2
- HLA-B27 for suspected spondyloarthropathies 2
When to Suspect Infection
Patients with suspected wrist infection should undergo joint aspiration immediately 1:
- Joint aspiration and synovial fluid analysis should be performed when joint effusion is present 2
Initial Management Based on Diagnosis
For osteoarthritis: Acetaminophen, NSAIDs, physical activity, and exercise; consider orthotics if pain impedes functioning 2
For inflammatory arthritis: Pharmacological treatment per rheumatology guidelines, physical activity, and exercise 2
For ganglion cysts with severe pain: Surgical excision is most effective for preventing recurrence (7-39% recurrence rate) 5
For suspected Kienböck disease without radiographic confirmation: MRI without IV contrast 1
For carpal tunnel syndrome: Clinical evaluation combined with electrophysiologic studies; imaging usually not needed, but ultrasound or MRI without contrast may be appropriate in selected circumstances 1, 4
Common Pitfalls to Avoid
- Do not skip radiographs: Even when clinical suspicion is high for soft tissue pathology, radiographs may reveal unexpected bony abnormalities 1, 2
- Do not use IV contrast routinely: It adds no benefit for most wrist pathology except suspected inflammatory arthritis 1
- Do not order bone scans, arthrography, or CT arthrography: These are not routinely used in modern wrist pain evaluation 1
- Refer to specialist if diagnosis remains unclear after appropriate imaging: Consider cineroentgenography, diagnostic arthrography, or arthroscopy 3, 6
