Wrist Pain: Workup and Treatment
Start with plain radiographs (PA and lateral views) as your initial imaging, then proceed to ultrasound or MRI without contrast based on clinical suspicion, with ultrasound being particularly useful for tendon and soft tissue pathology while MRI is reserved for suspected ligamentous, cartilage, or bone pathology that will change management.
Initial Clinical Assessment
Focus your history on these key elements that drive diagnosis:
- Onset pattern: Spontaneous or vague/distant trauma suggests carpal bone nonunion or avascular necrosis 1
- Pain location: Radial-sided versus ulnar-sided versus dorsal central narrows your differential significantly 2, 3
- Mechanism: Repetitive loading activities point toward overuse tendinopathies or stress injuries 1
- Functional limitations: Grip strength loss, specific activity restrictions
Physical examination should localize tenderness to specific anatomic structures and include targeted provocative tests:
- Anatomic snuffbox tenderness: Scaphoid pathology
- First CMC joint grinding test: Thumb carpometacarpal osteoarthritis
- Finkelstein's test: De Quervain tenosynovitis
- Watson's test: Scapholunate instability
- Lunotriquetral shear test: TFCC or lunotriquetral ligament injury 2, 1
Imaging Algorithm
First-Line: Plain Radiographs
Obtain PA and lateral views to evaluate:
- Bony architecture and alignment
- Joint space width and symmetry
- Soft tissue abnormalities
- Old fractures or arthritic changes 4, 1
Critical caveat: Do not let negative radiographs override clinical suspicion—history and physical examination lead to diagnosis in 70% of cases even before imaging 1.
Second-Line Imaging (Based on Clinical Suspicion)
Ultrasound is your next step when suspecting:
- Tendinopathy or tenosynovitis (de Quervain, ECU tendinopathy)
- Tendon tears or pulley injuries
- Ganglion cysts
- Carpal tunnel syndrome
- Joint effusions or synovitis
The ACR supports ultrasound for metacarpophalangeal/interphalangeal joint pain and tendon/soft tissue pathology, with studies showing it contributes to clinical assessment in 76% of hand/wrist cases 4. Ultrasound has the advantage of being readily available, cost-effective, and can be performed dynamically.
MRI without contrast when suspecting:
- Ligamentous injuries (scapholunate, lunotriquetral, TFCC)
- Occult fractures or bone stress injuries
- Avascular necrosis
- Cartilage pathology
- When diagnosis remains unclear after radiographs and ultrasound
MRI changed clinical management in 69.5% of referred cases and was particularly valuable in reassuring patients that no further follow-up was needed in 70% of cases 4. However, reserve MRI for cases where it will actually change management—don't order it as a fishing expedition 2.
Advanced imaging (CT, MR arthrography, CT arthrography):
- Generally best ordered by hand surgeons when clarifying diagnosis before surgical intervention 2
- CT arthrography has 94-100% sensitivity/specificity for articular cartilage injury in post-traumatic osteoarthritis 4
Imaging to Avoid
- Bone scan: No supporting literature for chronic wrist pain workup 4
- MRI with contrast: No routine indication; adds cost without benefit 4
- CT with IV contrast: Not performed in clinical practice 4
Treatment Approach
Conservative Management (First-Line for Most Conditions)
Immobilization and rehabilitation:
- For acute peri-scapholunate ligament injuries causing dorsal central wrist pain, a structured 16-week home-based program including immobilization and scapholunate-stabilizing muscle strengthening significantly reduces pain (5.1 cm improvement on VAS) and improves function 5
- Trial of immobilization for 3 weeks is cost-effective for verifying that pain originates from bone/joint abnormality before considering surgery 6
Condition-specific treatments:
- De Quervain tenosynovitis: Splinting, NSAIDs, corticosteroid injection
- Thumb CMC osteoarthritis: Splinting, NSAIDs, intra-articular injection
- Carpal tunnel syndrome: Wrist splinting, activity modification, corticosteroid injection
- Ganglion cysts: Observation (many resolve spontaneously), aspiration, or excision if symptomatic
When to Refer
Refer to hand surgery when:
- Diagnosis remains unclear after systematic workup 7
- Conservative management fails after appropriate trial
- Suspected scaphoid nonunion (risk of diffuse wrist osteoarthritis with delayed treatment) 2
- Ligamentous instability requiring surgical stabilization
- Advanced imaging is needed to guide surgical planning 2
Critical Pitfalls to Avoid
Don't perform surgery based solely on positive imaging findings without clinical correlation—bone scans and arthrography frequently show abnormalities without pathologic significance 6
Don't delay diagnosis of scaphoid fracture nonunion—this can progress to diffuse wrist osteoarthritis with poor outcomes 2
Don't order MRI reflexively—it should only be obtained when results will change management, ideally coordinated with hand surgery referral 2
Don't ignore clinical suspicion when imaging is negative—a systematic approach with history and physical examination establishes diagnosis in 78% of cases using only basic imaging 7
