Introduction[edit | edit source]
The biceps brachii muscle has two heads, one originating from the coracoid process (short head) and the other from the supraglenoid tubercle of the scapula and superior labrum (long head biceps). The long head (LHB) contributes to the stability of the glenohumeral joint. The majority of biceps rupture involves the LH. Rupture of the LHB tendon can be treated conservatively. Patients generally recover successfully if they receive a timely diagnosis and treatment
Chronic LHB rupture is defined as a tendon tear for more than 4 weeks. Chronic rupture may be due to missed diagnosis or failure of conservative treatment. MRI helps differentiate partial and complete tears of the biceps tendon.
Pathophysiology[edit | edit source]
The LH originates at the supraglenoid tubercle and is attached to the dorsal aspect of the radial tuburosity. It runs intra-articularly over the humeral head and follows the bicipital groove distal to the glenohumeral joint. It functions as dynamic stabilizer of the glenohumeral joint, as well as a depressor of the humeral head.
- Age, overuse, smoking, and corticosteroid use contribute to tendon degeneration and, later, tendinopathy.
- The proximal tendon rupture in most cases occurs at the tendon-labral junction or the bony attachment.

Epidemiology[edit | edit source]
- Biceps tendon rupture mainly occurs in individuals between 40 and 60 years who already have a history of shoulder problems.
- It mostly affects the dominant arm.
- A biceps tendon tear can also occur in younger individuals, but usually after a traumatic fall on an outstretched arm, heavy weightlifting or consistently sport activities such as snowboarding and soccer.
Etiology[edit | edit source]
- LHB rupture is generally not due to a unique mechanism of injury but is highly correlated with rotator cuff disease.
- Risk factors include age, smoking, obesity, use of corticosteroids, and overuse. Rare causes include the use of quinolones, diabetes, lupus, and chronic kidney disease.
Characteristics/Clinical presentation[edit | edit source]
Patients with a long head biceps rupture report a wide variety of symptoms.
- Audible pop
- Sharp anterior shoulder pain with or without snapping sensation
Associated pathologies that may lead to rupture of long head of biceps:
- Popeye deformity
Diagnostic procedures[edit | edit source]
Physical examination[edit | edit source]
- Assessment of the shoulder and arm contour:
- Muscle power: Shoulder and elbow
- Range of motion (ROM): Shoulder and elbow
- Special tests:

Outcome measures[edit | edit source]
Conservative Management[edit | edit source]
Anti-inflammatory medications can be used to reduce the underlying inflammatory process that may predispose tendons to rupture. When tendons are stressed or partially disrupted, anti-inflammatory medications can be used as analgesia.
Non-operative management is considered appropriate for older patients or patients who do not require a high level of supination strength. This is also considered for subacute or chronic biceps tendon tears.
Conservative management: Physiotherapy[edit | edit source]
Conservative management of long head of biceps rupture take 4-6 weeks on average. The treatment takes 4-6 weeks, 2-3 times in a week. Treatment consists of:
- Mobilization and flexibility exercises to improve the shoulder ROM. Followed by strength and stretching exercises. The muscle will also be static trained.
- At home there will be home exercises. The exercises are extension and flexion and supination and pronation exercises.
Most people go back to work after 2-3 weeks but the work is adapted. After 8 weeks the ROM and the strength is back to normal. Normally there aren’t anymore restrictions more but the popeye malformation remains. 
Phase 1: Acute phase[edit | edit source]
- Clinical modalities as needed
- Glenohumeral ROM:
- Joint mobilization to restrict capsular tissue
- Stretching as indicated
- Home exercise programme:
- ross-arm stretch
- Sleeper stretch
- Early scapular strengthening
- Scapular stabilization with instruction in lower trapezius facilitation
Phase 2: Subacute phase, early strengthening[edit | edit source]
- Continue with modalities and ROM.
- Begin rotator cuff strengthening with theraband:
- Internal/external rotation in 30° abduction
- Low rows (prone, scapular plane abduction (<90°), ceilling punch, biceps and triceps)
Phase 3: Advanced strengthening[edit | edit source]
- Continue with strengthening:
- Resisted PNF patterns
- Theraband exercises:
- Bear hug
- Reverse fly
- Internal/external roation at 90° abduction for neuromuscular re-education
- Push-up progression
- Begin with plyometric exercises with both arms, progressing to one arm
- Weight training
Phase 4: Return to activities[edit | edit source]
- Continue with program
- Re-evaluation with physician and therapist
- Advance to return-to-sport program, as motion and strength allow
Surgery[edit | edit source]
Non-surgical treatment is usually sufficient for proximal tendon rupture as it is more common in elderly patients. However, residual cosmetic deformity and some intermittent biceps muscle cramping may persist. Younger patients and female patients who are unwilling to accept cosmetic deformity and athletic patients with frequent cramping may opt for surgical intervention in the form of biceps tenodesis. The presence of associated rotator cuff pathology can also influence surgical management. Subpectoral tenodesis is the preferred approach for biceps tenodesis, where the tendon is attached to the bone in the bicipital groove. Sometimes this procedure is done concurrently with arthroscopic rotator cuff pathology treatment. Newer implants like interference screws and bio-absorbable suture anchors can be placed either through the open or arthroscopic approach to secure the tendon in the subpectoral space. All the approaches mentioned above are reported to achieve good clinical outcomes. However, there is limited data to show the superiority of the surgical intervention to the non-surgical approach
Post-operative rehabilitation: Physiotherapy management[edit | edit source]
Patients have to wear a mastersling for the first 10-14 days after surgery. Only passive range of motion is allowed in that time. Light exercises is done from week 2 to 6, where after it is progressed to functional exercises between week 6 and 8, and progressed to resistance. After this, moderate loading may be tolerated but heavy loading is prohibited for the first few months.
Phase 1: Passive (Week 0-2)[edit | edit source]
- Warm up with pendulum exercises
- Passive ROM
- Full passive elbow flexion/extension ROM
- Full passive forearm supination/pronation ROM
- Full passive shoulder ROM
- Seated scapular retractions
Phase 2: Active (Week 2-6)[edit | edit source]
- Warm up with pendulum exercises
- Active ROM, with terminal stretch to prescribed limits
- Full active shoulder ROM, lawn chair progression
- Full active elbow flexion/extension ROM
- Full active forearm supination/pronation ROM
Phase 3: Resisted (Week 6-8)[edit | edit source]
- Warm up with pendulum exercises
- Theraband exercises:
- Shoulder internal/external rotation at 30° abduction
- Standing forward punch
- Low rows
- Bear hugs
- Prone I,T,Y,W.
- Biceps curls
- Resisted supination/pronation
Phase 4: Weight training (Week 8+)[edit | edit source]
- Keep hands within eyesight, keep elbows bent, minimize overhead activities
- Return to normal activities:

Clinical Bottom Line[edit | edit source]
Long head of biceps ruptures commonly occur in the population between 40 and 60 with predisposing shoulder problems. It can also occur in the younger, active population. It is characterized by a Popeye sign at the biceps. Conservative management consisting of analgesia and physiotherapy is the treatment of choice for the older population, and for patients that does not need full supination strength, as an up to 20% loss with biceps ruptures are normally present. Surgery consisting of a tenotomy and re-attachment of the tendon are mostly reserved for the younger, more active population; patients who cannot aesthetically accept the Popeye appearance; as well as patients needing full supination strength (mostly for manual labour). Physiotherapy plays a massive role in both the conservative, as well as post-surgical management of a long head of biceps rupture.
