How should I evaluate and treat a patient with a one-month history of bilateral wrist pain, initially right wrist then left, constant moderate pain (6/10), thumb weakness, and no current medications?

Evaluation and Treatment Approach

Start with bilateral wrist radiographs (posteroanterior, lateral, and oblique views) and initiate naproxen for symptomatic relief while pursuing a focused workup for inflammatory arthritis, carpal tunnel syndrome, or De Quervain tenosynovitis given the bilateral presentation and thumb weakness. 1

Initial Imaging

Radiography is the appropriate first imaging study for chronic wrist pain 1. The standard three-view series (posteroanterior, lateral, oblique) allows assessment of:

• Joint space narrowing suggesting arthritis
• Ulnar variance and alignment abnormalities
• Occult or nonunited fractures
• Soft tissue swelling or mineralization
• Erosive changes

Do not order MRI, CT, or bone scan as initial imaging - these are not supported as first-line studies and should be reserved for specialist-directed evaluation if radiographs are unrevealing 1.

Critical Laboratory Workup

Given the bilateral, progressive nature with thumb weakness, order:

• Rheumatoid factor and anti-CCP antibodies - bilateral wrist involvement raises concern for inflammatory arthritis
• ESR and CRP - to assess for inflammatory process
• Complete metabolic panel - baseline before NSAID therapy

The bilateral progression from right to left over one month is a red flag pattern that warrants inflammatory arthritis evaluation 2.

Key Physical Examination Findings to Document

Focus your examination on:

• Thenar muscle bulk and strength - thumb weakness suggests either carpal tunnel syndrome or CMC joint arthritis
• Tinel's and Phalen's signs - carpal tunnel syndrome commonly presents with thumb weakness
• Finkelstein's test - De Quervain tenosynovitis can cause radial-sided pain with thumb weakness
• CMC grind test - thumb carpometacarpal osteoarthritis is common and causes thumb weakness
• Palpation of anatomic snuffbox - scaphoid pathology
• Assessment for synovitis - boggy, warm joints suggest inflammatory process

Treatment Initiation

Naproxen 500 mg twice daily with food is appropriate for symptomatic management while awaiting workup results. This provides anti-inflammatory coverage for both mechanical and inflammatory etiologies.

Common Pitfalls to Avoid

• Do not dismiss bilateral presentation as simple overuse - the progression from unilateral to bilateral over weeks suggests systemic process 2
• Do not delay inflammatory workup - conditions like rheumatoid arthritis have better outcomes with early diagnosis and treatment 2, 3
• Do not attribute thumb weakness solely to pain - this finding narrows your differential significantly and warrants nerve conduction studies if carpal tunnel is suspected
• Do not order advanced imaging without plain films first - this violates established imaging algorithms and wastes resources 1

Referral Thresholds

Refer to hand surgery or rheumatology if:

• Radiographs show erosive changes, scaphoid nonunion, or significant arthritis
• Laboratory studies suggest inflammatory arthritis
• No improvement after 4-6 weeks of conservative management
• Progressive weakness or functional decline

The one-month duration with constant moderate pain and bilateral involvement makes this a subacute presentation requiring systematic evaluation rather than simple reassurance 2, 3.
