Chronic Thumb/Wrist Pain After Orthopedic Surgery

Step 1 - Identify the Cause

Step 2 - Workup

• Detailed history: onset, character, location, aggravating factors
• Examination: grind test, Finkelstein test, neurovascular exam, skin temperature/color
• Imaging: X-ray to check hardware, joint space, and alignment; MRI if soft tissue or tendon pathology suspected
• Bone scan or three-phase scan if CRPS suspected

Step 3 - Treatment by Cause

A. CRPS (Complex Regional Pain Syndrome)

• Physical/occupational therapy is the cornerstone - desensitization, mirror therapy, graded motor imagery
• Pharmacologic: gabapentin or pregabalin (first-line for neuropathic component); low-dose tricyclics (amitriptyline); NSAIDs; short-course oral corticosteroids in early stages
• Interventional: stellate ganglion block can reduce sympathetically maintained pain and facilitates physiotherapy; continuous peripheral nerve blocks (e.g. brachial plexus catheter) for refractory cases
• Bisphosphonates (e.g. alendronate) have evidence for bone pain in CRPS
• Per Miller's Anesthesia: regional techniques including stellate ganglion blockade and continuous peripheral nerve blocks reduce pain scores and enable functional rehabilitation in CRPS

B. Persistent Thumb CMC / Basal Joint Pain

• Conservative (first-line post-op): thumb spica splint to rest the joint; topical diclofenac gel (Voltaren); oral NSAIDs (ibuprofen, naproxen, celecoxib); corticosteroid injection into the CMC joint
• Hand therapy: strengthening of intrinsic muscles, thumb opposition exercises, ergonomic modification
• If surgery failed or disease progressed: options include:
  • Trapezectomy (removal of trapezium)
  • Ligament reconstruction and tendon interposition (LRTI)
  • Joint arthroplasty
  • Arthrodesis (joint fusion) - best for younger, high-demand patients; eliminates pain but sacrifices mobility
  • Per Campbell's Operative Orthopaedics (2026): outcomes after simple trapezectomy vs. LRTI are similar, with good results in ~78% of patients

C. Hardware-Related Pain

• Symptomatic hardware (particularly prominent volar plate screws) should be removed once fracture is healed (typically 12-18 months post-op)
• Per Miller's Review of Orthopaedics: patients with ORIF should be monitored for symptomatic hardware that may require removal to prevent tendon rupture

D. Neuropathic / Nerve Pain

• Gabapentinoids (gabapentin 300-1200 mg/day or pregabalin 75-300 mg/day)
• Tricyclic antidepressants (amitriptyline 10-50 mg at night)
• Topical lidocaine patches over the area
• If neuroma: ultrasound-guided corticosteroid injection around the neuroma; surgical excision if refractory

E. General / Multimodal Pain Management

• NSAIDs / COX-2 inhibitors (e.g. celecoxib, ibuprofen) for inflammatory pain
• Acetaminophen as baseline analgesic (scheduled, not PRN)
• Gabapentinoids for neuropathic component
• Opioids only if above insufficient - use lowest effective dose and taper; avoid long-term opioid monotherapy
• Topical agents: diclofenac gel, capsaicin cream (useful for localized pain)
• Corticosteroid injection for local inflammatory flares

Step 4 - Rehabilitation

• Scar management and desensitization - massage, silicone gel sheets
• Range-of-motion exercises: gentle thumb abduction/opposition, wrist flexion/extension, forearm rotation
• Edema control: elevation, compression wrapping
• Progressive strengthening: grip exercises, pinch strengthening, soft-ball squeezes
• Ergonomic education: avoid repetitive pinch-grip motions; use adaptive equipment; lift objects with palm rather than thumb pinch

When to Re-refer

• Pain is worsening despite 6-8 weeks of conservative treatment
• Suspected hardware complication (tendon rupture risk)
• Signs of CRPS not responding to initial management
• New or progressive neurological symptoms
