What is the appropriate management for a 38-year-old male presenting with acute right biceps pain and swelling after hearing an audible pop while performing biceps curls?

Acute Biceps Tendon Rupture Management

This patient has sustained an acute proximal biceps tendon rupture and should receive immediate ice therapy, relative rest with activity modification, NSAIDs for pain control, and urgent orthopedic referral within 1-2 weeks to determine if surgical repair is indicated, as acute ruptures in young active individuals often benefit from early surgical intervention to restore strength and function.

Immediate Management (First 24-72 Hours)

Cryotherapy Protocol

• Apply ice therapy immediately using melting ice water through a wet towel for 10-minute intervals to reduce pain and swelling 1
• Repeat ice applications every 20 minutes during the acute phase, as intermittent 10-minute cooling is as effective as continuous 20-minute applications 1
• Continue ice therapy for the first 48-72 hours, as cold application is superior to heat in early reduction of edema 1
• The target is to reduce tissue temperature by 10-15°C, which is most effectively achieved with repeated rather than continuous applications 2

Activity Modification and Protection

• Implement relative rest immediately to prevent further tendon damage and promote healing 3, 4
• Avoid complete immobilization to prevent muscle atrophy and deconditioning 5
• Restrict biceps-loading activities including lifting, pulling, and overhead movements 3
• Consider a supportive sling for comfort during the first few days, but encourage gentle range of motion of the elbow and shoulder to prevent stiffness 1

Pain Management

• Prescribe NSAIDs for short-term pain relief and inflammation control 5, 6
• NSAIDs provide symptomatic relief but do not alter long-term outcomes 5
• If pain is the only symptom, analgesics alone may be sufficient 6

Diagnostic Confirmation and Referral

Clinical Assessment

• The audible "pop" with immediate pain and swelling above the AC joint (likely proximal biceps attachment) strongly suggests acute tendon rupture 4
• Physical examination should reveal a visible "Popeye deformity" (bunching of the biceps muscle belly distally) if this is a proximal long head biceps rupture
• Assess for weakness with elbow flexion and forearm supination, though pain may limit initial strength testing 4

Urgent Orthopedic Referral

• Refer to orthopedic surgery within 1-2 weeks for evaluation and consideration of surgical repair 3
• In a 38-year-old active male, surgical repair is often indicated to restore optimal strength and function, particularly for proximal biceps ruptures
• Delayed surgical intervention beyond 3-4 weeks significantly compromises outcomes due to tendon retraction and muscle atrophy

Common Pitfalls to Avoid

• Do not delay orthopedic referral beyond 2 weeks, as early surgical intervention (within 3-4 weeks) provides the best functional outcomes for acute ruptures in young active patients 3
• Avoid excessive ice application beyond 20 minutes continuously, as this can cause tissue damage without additional benefit 1
• Do not apply heat in the acute phase, as cold is superior for reducing early edema 1
• Avoid premature return to aggravating activities before adequate healing, which can lead to recurrence or incomplete recovery 5
• Do not misdiagnose this as chronic tendinopathy requiring conservative management—the acute presentation with audible pop indicates rupture requiring different management 3, 4

Expected Recovery Timeline

• With appropriate acute management and timely surgical evaluation, most patients can expect significant improvement within 3-6 months 3, 4
• Surgical repair typically requires 4-6 months of rehabilitation before return to full activity
• Non-operative management (if chosen for distal biceps or in older/less active patients) may result in 20-30% loss of supination strength and 10-15% loss of flexion strength
