Initial Management of Carpal Tunnel Syndrome
For patients with mild to moderate carpal tunnel syndrome, begin with nighttime wrist splinting in neutral position as first-line therapy, which should be attempted for 4-6 months before considering surgical intervention. 1
Conservative Management Algorithm
First-Line Treatment (Weeks 0-4)
- Wrist splinting in neutral position for nocturnal wear is the cornerstone of initial conservative management 1, 2
- Discontinue ineffective over-the-counter NSAIDs (acetaminophen, ibuprofen) as they do not address median nerve compression and have limited efficacy for nerve entrapment 1, 3
- Implement activity modification including avoidance of sustained gripping activities and awkward wrist positions 4
- Consider nerve-gliding exercises as an adjunct to splinting 4
Second-Line Treatment (If No Improvement at 2-7 Weeks)
- Local corticosteroid injection provides superior relief compared to oral steroids and can delay surgery for more than one year 1, 2, 5
- Oral corticosteroids are an option for short-term management (2-4 weeks) but are less effective than local injection 5, 3
- Therapeutic ultrasound may be considered as an adjunctive option 2, 5
- Yoga has shown some benefit and can be incorporated 4, 2
Critical Pitfalls to Avoid
- Do not proceed directly to surgery in patients with very mild electrodiagnostic findings without attempting conservative treatment, as 48-63% will respond to conservative measures 1
- Avoid injecting corticosteroids within 3 months of planned surgery if conservative treatment fails, as this increases infection risk 1
- Do not rely on NSAIDs, diuretics, or vitamin B6 as these are no more effective than placebo 1, 3
- Avoid excessive or prolonged immobilization as it can lead to muscle deconditioning and potentially worsen symptoms 1
When to Proceed to Surgery
Surgical decompression should be offered when:
- Symptoms persist after 4-6 months of conservative management 1, 2
- Moderate-to-severe carpal tunnel syndrome is present at diagnosis 1
- Clinical evidence of median nerve denervation exists 5
- Patient preference after informed discussion of options 5
Surgical Considerations
- Both open and endoscopic carpal tunnel release are equally effective for symptom relief 1
- Endoscopic repair allows patients to return to work approximately one week earlier than open technique 1, 2
- Obtain electrodiagnostic studies before surgery to determine severity and surgical prognosis 1, 2
Diagnostic Confirmation
While typical cases can be diagnosed clinically, consider:
- Electrodiagnostic studies when clinical examination is positive and surgical management is being considered 1
- Ultrasound to measure median nerve cross-sectional area in atypical presentations 1
- Laboratory testing (HbA1c, TSH) only when atypical features suggest systemic disease—routine testing generates more false positives than true positives 1
