Management of Hand Osteoarthritis

Non-Pharmacological Interventions

• The European League Against Rheumatism recommends first CMC joint neoprene or rigid orthoses for first CMC joint OA, with long-term use (at least 3 months) advocated for optimal symptom relief 1, 2
• Custom-made orthoses are preferred to ensure proper fit and improve patient compliance, as suggested by the Annals of the Rheumatic Diseases 2
• Orthoses for other hand joints are conditionally recommended as the disease progresses to involve additional joints, according to Arthritis care & research 3
• Exercise regimens involving both range of motion and strengthening exercises should be considered for all patients, as recommended by the Annals of the Rheumatic Diseases 4, 2
• Exercises should specifically aim at improving joint mobility, muscle strength, and thumb base stability, as suggested by the Annals of the Rheumatic Diseases 2
• Joint protection education to minimize stress on affected joints is essential, according to the Annals of the Rheumatic Diseases 2
• Local application of heat (e.g., paraffin wax, hot packs), especially before exercise, can provide symptomatic relief, as recommended by the Annals of the Rheumatic Diseases 4, 5
• Heat therapy has stronger evidence of benefit (77% recommendation strength) compared to ultrasound (25% recommendation strength), according to the Annals of the Rheumatic Diseases 4, 5

Pharmacological Interventions

• Topical treatments are preferred over systemic treatments due to safety considerations, especially for mild to moderate pain and when only a few joints are affected, as recommended by the Annals of the Rheumatic Diseases 4, 5
• Topical NSAIDs are the first-line pharmacological treatment for hand OA, according to the Annals of the Rheumatic Diseases 2
• Paracetamol (acetaminophen) up to 4g/day is the oral analgesic of first choice due to its efficacy and safety profile, as recommended by the Annals of the Rheumatic Diseases 4, 5
• Oral NSAIDs should be used at the lowest effective dose and for the shortest duration in patients who respond inadequately to paracetamol, according to the Annals of the Rheumatic Diseases 4, 5
• In persons age ≥75 years, topical rather than oral NSAIDs are recommended due to safety concerns, as suggested by Arthritis and Rheumatology 6
• For patients with increased gastrointestinal risk, non-selective NSAIDs plus a gastroprotective agent or a selective COX-2 inhibitor should be used, according to the Annals of the Rheumatic Diseases 4, 5
• Intra-articular injection of long-acting corticosteroid is effective for painful flares of OA, especially for the trapeziometacarpal joint, as recommended by the Annals of the Rheumatic Diseases 4, 5

Surgical Interventions

• For severe thumb base OA, surgical options (e.g., interposition arthroplasty, osteotomy, or arthrodesis) should be considered in patients with marked pain and/or disability when conservative treatments have failed, according to the Annals of the Rheumatic Diseases 4, 5

Treatment Algorithm

• First-line management includes first CMC joint orthosis/splint (custom-made if possible), joint protection education and exercise program, topical NSAIDs, and heat therapy before exercises, as recommended by Arthritis and Rheumatology 1, 2 and the Annals of the Rheumatic Diseases 4, 5
• Second-line management includes adding acetaminophen (up to 4g/day), according to the Annals of the Rheumatic Diseases 4, 5
• Third-line management includes short-term oral NSAIDs at lowest effective dose and considering intra-articular corticosteroid injection for painful flares, especially in the CMC joint, as recommended by the Annals of the Rheumatic Diseases 4, 5

Common Pitfalls and Caveats

• Splinting is most effective when used consistently for at least 3 months; shorter periods may not show significant benefit, as suggested by the Annals of the Rheumatic Diseases 2
• Exercise regimens for the first CMC joint differ from those for interphalangeal joints and should be tailored accordingly, according to the Annals of the Rheumatic Diseases 2

Initial Treatment for Osteoarthritis of the Hands

Non-pharmacological Interventions

• The European League Against Rheumatism recommends that all patients with hand osteoarthritis should be offered information on the nature and course of hand OA, as well as education on self-management principles and treatment options 7
• Self-efficacy and self-management programs are strongly recommended as they help patients understand their condition and actively participate in their care, according to the American College of Rheumatology 8
• Instruction in joint protection techniques should be provided to every patient to minimize stress on affected joints, as suggested by the European League Against Rheumatism 7, 9
• Evaluation of the patient's ability to perform activities of daily living (ADLs) is essential, according to the American College of Rheumatology 9
• Assistive devices should be provided as needed to help patients perform ADLs more comfortably, as recommended by the European League Against Rheumatism 7, 9
• Exercises to improve function and muscle strength, as well as to reduce pain, should be considered for every patient, according to the European League Against Rheumatism 7
• Splints are strongly recommended for patients with thumb base (trapeziometacarpal joint) OA, as suggested by the American College of Rheumatology 7, 10
• Long-term use of orthoses is advocated for symptom relief, according to the European League Against Rheumatism 7
• For joints other than the first carpometacarpal joint, orthoses may be considered but with a lower level of recommendation, as suggested by the American College of Rheumatology 8
• Patients should be instructed in the use of thermal modalities (heat and cold) for pain relief, according to the American College of Rheumatology 9
• Local application of heat (e.g., paraffin wax, hot packs), especially before exercise, can provide symptomatic relief, as recommended by the European League Against Rheumatism 11

Pharmacological Interventions

• Topical treatments are preferred over systemic treatments because of safety reasons, according to the European League Against Rheumatism 7
• Topical NSAIDs are the first pharmacological treatment of choice for hand OA, as recommended by the European League Against Rheumatism 7, 9
• Topical capsaicin may be considered as an alternative topical treatment, according to the American College of Rheumatology 9
• Oral NSAIDs, including COX-2 selective inhibitors, should be considered for a limited duration for relief of symptoms when topical treatments are insufficient, as suggested by the European League Against Rheumatism 7, 9
• In persons age ≥75 years, topical rather than oral NSAIDs are recommended due to safety concerns, according to the American College of Rheumatology 9
• Tramadol may be considered for patients with inadequate response to other analgesics, as recommended by the American College of Rheumatology 9

Common Pitfalls and Caveats

• Intra-articular therapies and opioid analgesics are conditionally recommended against in the initial management of hand OA, according to the American College of Rheumatology 9
• Long-term use of oral NSAIDs should be avoided due to potential gastrointestinal, cardiovascular, and renal adverse effects, as suggested by the European League Against Rheumatism 7
• Conventional or biological disease-modifying antirheumatic drugs should not be used in patients with hand OA, according to the European League Against Rheumatism 7
• Surgery should only be considered when other treatment modalities have not been sufficiently effective in relieving pain, as recommended by the European League Against Rheumatism 7

Evidence‑Based Management of Thumb Base Osteoarthritis

Surgical Management

• Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) is the established gold‑standard operation for severe thumb CMC osteoarthritis that has failed conservative therapy, providing reliable pain relief and functional improvement. 12
• Total joint replacement (TJR) may be considered, but comparative evidence with trapeziectomy + interposition arthroplasty is of limited quality (risk ratio = 5.00; 95 % CI 0.26–95.02). 12

Non‑Operative First‑Line Therapy

• Custom‑made rigid or neoprene CMC orthoses worn continuously for at least 3 months are required for clinical benefit; shorter durations are ineffective. 13
• Custom‑fabricated orthoses improve patient compliance compared with prefabricated devices. 13
• Topical non‑steroidal anti‑inflammatory drugs (NSAIDs) are the preferred initial pharmacologic option because they show a moderate effect size (ES = 0.77; 95 % CI 0.32–1.22) and no increased gastrointestinal risk versus placebo (RR = 0.81; 95 % CI 0.43–1.56). 12
• A structured exercise program that targets CMC joint mobility, thumb‑base muscle strength, and stability is essential; these exercises differ from those used for interphalangeal joints. 13
• Joint‑protection education to reduce mechanical stress on the thumb base should be provided to all patients. 13
• Heat therapy (e.g., paraffin wax or hot packs) applied before exercise sessions offers symptomatic relief. 12

Non‑Operative Advanced/Third‑Line Therapy

• Oral NSAIDs should be used at the lowest effective dose for the shortest possible duration when topical agents are insufficient. 13
• In patients aged ≥ 75 years, oral NSAIDs should be avoided; topical NSAIDs remain the preferred option regardless of response. 14
• For individuals at increased gastrointestinal risk, a non‑selective NSAID combined with a gastro‑protective agent or a selective COX‑2 inhibitor is recommended. 12

Indications for Surgical Intervention

• Surgery is indicated when marked pain and/or functional disability persist after ≥ 6 months of comprehensive conservative management—including orthosis use, pharmacologic therapy, and targeted exercise. 13

Critical Clinical Considerations

• Orthosis duration: Splinting must be maintained for a minimum of 3 months; benefits are not observed with shorter wear periods. (Evidence strength: moderate) 13
• Exercise prescription: CMC‑specific exercise protocols are required; generic finger‑joint exercises are inadequate. (Evidence strength: moderate) 13
• NSAID sequencing: Topical NSAIDs should be exhausted before initiating oral NSAIDs due to a more favorable safety profile. (Evidence strength: moderate) [13][12]
• Elderly patients (≥ 75 years): Prefer topical over oral NSAIDs to minimize systemic adverse effects. (Evidence strength: moderate) 14
