What is the recommended management plan for a patient with left shoulder pain and restricted movement, diagnosed with osteoarthritis (OA) and calcification, based on X-ray findings?

Management of Left Shoulder Osteoarthritis with Calcification

Begin with a structured non-pharmacological approach centered on exercise and physical therapy, followed by topical NSAIDs as first-line pharmacological treatment, reserving intra-articular corticosteroid injections for refractory cases. 1, 2

Initial Non-Pharmacological Management

Exercise and Physical Therapy (Strongly Recommended)

• Exercise therapy is the cornerstone of OA management and should be initiated immediately 1, 2
• Physical therapy targets three specific goals for glenohumeral OA: (1) decrease pain, (2) increase shoulder range of motion, and (3) protect the glenohumeral joint through rotator cuff strengthening 2
• Supervised exercise programs are more effective than home-based programs alone, ideally delivered by physical therapists 1
• Physical therapy is most effective for motion-related pain rather than rest pain in shoulder OA 2
• Identify specific soft tissues responsible for ROM loss and target them for intervention 2
• Rotator cuff strengthening exercises are essential to protect the glenohumeral joint from further degeneration 2

Self-Management Programs (Strongly Recommended)

• Self-efficacy and self-management programs combining skill-building, education, and exercise goals should be incorporated 1
• These multidisciplinary group-based programs include goal-setting, problem-solving, joint protection measures, and medication education 1
• Sessions can be led by health educators, nurses, physical therapists, or physicians, either in-person or online 1

Mind-Body Interventions (Strongly Recommended)

• Tai chi is strongly recommended for OA patients, combining meditation with slow movements, deep breathing, and relaxation 1
• This holistic practice impacts strength, balance, fall prevention, depression, and self-efficacy 1

Pharmacological Management

First-Line: Topical Therapy

• Topical NSAIDs should be the initial pharmacological treatment due to effectiveness with minimal systemic exposure 1, 3, 4
• This approach prioritizes treatments with the least systemic toxicity 1

Second-Line: Oral Medications

• Acetaminophen is recommended for mild to moderate pain when topical therapy is insufficient 4, 5, 6
• Oral NSAIDs at the lowest effective dose for the shortest duration should be considered if acetaminophen and topical NSAIDs are inadequate 1, 4, 6
• NSAIDs are more effective than acetaminophen for moderate-to-severe pain but carry increased gastrointestinal and cardiovascular risks 6
• Consider gastroprotection with a proton pump inhibitor if at high gastrointestinal bleeding risk 1

Intra-Articular Injections

• Corticosteroid injections provide longer-term pain relief for advanced cases refractory to oral medications 4, 5
• These injections are appropriate for disease flares and provide short-term pain relief 5
• Hyaluronic acid injections have mixed evidence for efficacy in shoulder OA 2

Management of Calcification

Addressing the Greater Tuberosity Calcification

• The calcification noted in soft tissues near the greater tuberosity likely represents calcific tendinopathy 2
• Physical therapy remains the primary treatment, focusing on ROM restoration and rotator cuff strengthening 2
• If calcific deposits cause significant symptoms refractory to conservative management, consider referral for potential arthroscopic debridement 4

Assessment of Treatment Response

Pain Characteristics Matter

• Determine whether pain occurs at rest or during motion, as physical therapy is more effective for motion-related pain 2
• Assess for abnormal scapular motion, which commonly develops as adaptation to restricted glenohumeral motion 2

Monitoring Disease Progression

• Regular follow-up is necessary to assess treatment effectiveness and adjust the management plan 3
• The degree of arthritis visible on radiography combined with symptom severity determines treatment escalation 4

Common Pitfalls and Caveats

Medication Safety

• Avoid prolonged use of oral NSAIDs due to gastrointestinal, cardiovascular, and renal risks 1, 6
• Assess for hypertension, cardiovascular disease, heart failure, gastrointestinal bleeding risk, and chronic kidney disease before finalizing pharmacological treatment 1
• COX-2 specific inhibitors have better gastrointestinal safety profiles than traditional NSAIDs but similar efficacy 6

Realistic Expectations

• Pain relief does not alter the underlying disease progression 5
• Biologics (platelet-rich plasma, bone marrow aspirate concentrate, mesenchymal stem cells) may decrease pain but neither stop progression nor improve OA 2

When to Consider Surgical Referral

Indications for Surgery

• Surgical options should be considered if symptoms substantially affect quality of life despite comprehensive conservative treatment 3, 4
• Surgical options include arthroscopic debridement, arthroscopic capsular release, hemiarthroplasty, or total shoulder arthroplasty for severe cases 4
• Joint replacement generally provides excellent results for advanced disease 5

Adjunctive Considerations

Nutritional Supplementation

• Supplementation with oral vitamin C and vitamin D may help slow cartilage degeneration 2
• Glucosamine sulfate and chondroitin sulfate have slower, less pronounced symptomatic effects than NSAIDs, with some evidence for structural benefits 6

Activity Modification

• Combined approach of activity modification and physical therapy can be effective 2
• Patient education about joint protection techniques is essential 3
