Ruptured Biceps: Symptoms, Treatment and Recovery

01Anatomy

The biceps tendons

The biceps brachii has two heads at the shoulder (long and short) and a single distal tendon at the elbow. It flexes the elbow and, importantly, rotates the forearm palm-up (supination). Rupture can occur at the shoulder end (proximal long head, the most common, about 90–95% of biceps ruptures) or at the elbow end (distal, less common but functionally more significant).

02Symptoms

Symptoms

• A sudden pop or snap, sometimes a tearing sensation, during lifting.
• Immediate sharp pain, which often settles within days.
• Bruising spreading down the arm.
• A bulge in the upper arm (“Popeye muscle”) when the muscle retracts toward the elbow in proximal tears, or a bulge higher in the arm and a gap near the elbow crease in distal tears.
• Weakness bending the elbow and, in distal tears, turning the palm up (supination).
• Cramping with repetitive use.

03Causes

Causes and risk factors

• Heavy lifting with a sudden eccentric load (the muscle contracting while being stretched).
• Age over 40–50: tendons degenerate; many proximal tears occur with minimal force.
• Chronic rotator cuff disease or biceps tendinopathy.
• Smoking, corticosteroid use and anabolic steroids.
• Repetitive overhead activity.
• Distal tears: men aged 30–50 and weightlifters.
• See biceps tendonitis for the earlier irritation stage.

04Diagnosis

Diagnosis

The clinician examines the arm, tests the strength of elbow flexion and forearm supination and uses manoeuvres such as the hook test (for distal tears). Ultrasound or MRI confirms the rupture, shows whether it is partial or complete and checks for associated rotator cuff tears. X-rays rule out fractures.

05Proximal

Proximal (shoulder) rupture: treatment

• Non-surgical treatment is usual: rest, ice, pain relief, then physical therapy for shoulder and elbow strength and mobility.
• Most people retain about 80–90% of elbow strength and function; a cosmetic deformity may remain.
• Surgery (tenodesis) may be considered for younger active people, manual workers, athletes who need maximal strength, or when there is a painful cramping or cosmetic concern.
• Pain typically resolves within weeks; recovery of strength takes 3–6 months.

06Distal

Distal (elbow) rupture: treatment

• Surgical repair is usually recommended for active adults, ideally within 2–3 weeks, because the tendon retracts and scars with time.
• Techniques re-attach the tendon to the radius using anchors, buttons or screws.
• Non-surgical treatment may be suitable for older, low-demand patients or those unfit for surgery, accepting loss of supination strength (about 30–40%) and flexion strength (about 20–30%).
• Risks of surgery include nerve irritation, stiffness, re-rupture and heterotopic bone.
• Delayed repair may require tendon grafts.

07Rehab

Rehabilitation

• Weeks 0–6 after surgery: protection in a splint or brace, with early gentle range-of-motion as directed.
• Weeks 6–12: active movement, then light resistance, avoiding heavy lifting.
• Months 3–6: progressive strengthening of biceps, forearm and shoulder, return to heavier activity and sport.
• For non-surgical care: gentle mobility, then progressive biceps, rotator cuff and scapular strengthening over 6–12 weeks.
• Follow your surgeon’s protocol; rushing increases the risk of re-rupture.

08Prevent

Prevention

• Treat biceps and shoulder pain early.
• Warm up properly before lifting.
• Avoid sudden heavy lifting, particularly jerking motions.
• Increase weights gradually and use good technique.
• Stop smoking, and avoid anabolic steroids.
• Strengthen the rotator cuff and scapular muscles. See supraspinatus injury.

10Cases

Three common situations

A 55-year-old feels a pop in the shoulder while lifting a box and notices a bulge: likely proximal long head rupture; rehabilitation is usually effective.

A 38-year-old weightlifter feels a snap at the elbow crease and cannot turn the palm up: suspect distal rupture; see a specialist promptly.

An athlete wanting to maintain maximum strength: discuss surgery and rehabilitation options with an orthopaedic surgeon.

11Daily life

Managing daily life while it heals

Use the other arm for heavy tasks, carry loads close to the body, avoid lifting with the forearm turned upward against resistance and take it easy with jars, screwdrivers and heavy doors. A sling is rarely needed for proximal tears beyond a few days, but after distal repair a brace is worn as directed. Gentle finger, wrist and shoulder movement prevents stiffness. Return to driving and work depends on your job and surgeon’s advice.

12Summary

Key points to remember

Most proximal biceps ruptures heal functionally without surgery, whereas distal ruptures are usually repaired early. Seek assessment after a pop, follow rehabilitation carefully and return to heavy lifting gradually. Our physical therapy team can guide your recovery.
