Biceps tendon rupture causes symptoms and treatment

A biceps tendon rupture may seem like a sudden injury, but in many cases it develops as a result of accumulated strain or excessive stress placed on the arm over time. This condition directly affects arm strength and daily movement, making it an injury that should not be ignored.The severity of the tear varies from one case to another. It may be a mild tear that can be managed with conservative treatment, or a complete rupture that requires precise medical intervention. This highlights the importance of understanding its causes and symptoms, as well as knowing the chances of recovery, in order to deal with the condition properly and avoid complications that may affect arm function and mobility later on.

What Is a Biceps Tendon Tear?

A biceps tendon tear is an injury that occurs in the tendon connecting the biceps muscle to the bones. The tear may be partial or complete, and it most commonly happens in the shoulder or elbow area due to a sudden movement or unexpectedly lifting a heavy object.

This injury usually causes noticeable symptoms such as:

Sudden sharp pain
A “popping” sound at the moment of injury
Swelling in the affected area
Bruising

Mild cases may be treated with rest, cold compresses, and conservative therapy, while complete tears often require surgery to reconnect the tendon to the bone, followed by a recovery period that may last several weeks.

⏱️ How Long Does Biceps Tendon Surgery Take?

Biceps tendon repair surgery usually takes about one to two hours, depending on the severity of the tear and the patient’s overall health condition.

During the procedure, the surgeon reattaches the torn tendon to the bone to restore normal arm function and stability.

❓ Can a Torn Biceps Tendon Heal on Its Own?

A completely torn tendon does not heal back to normal on its own without medical treatment.

However, a partial tear may improve with rest and physical therapy, as the body can gradually compensate for part of the lost function. Still, this does not always mean the tendon returns fully to its original condition.

❓ What Is the Difference Between a Shoulder Tear and an Elbow Tear?

Shoulder Tendon Tear

Usually less severe
May sometimes be treated without surgery

Elbow Tendon Tear

More serious
Significantly affects arm strength and rotation
Often requires surgical repair

❓ Does Pain Continue After a Biceps Tear?

In the early stages, the pain is usually severe and sudden, but it may gradually decrease over time. However, untreated or complete tears may later lead to:

Weakness in the arm
Changes in muscle shape

❓ Does the Shape of the Arm Change After a Biceps Tendon Tear?

Yes, especially in complete tears. When the tendon separates, the muscle may retract, causing visible changes such as:

A noticeable bulge or “ball-like” appearance in the upper arm
Mild asymmetry between both arms
Loss of the muscle’s normal contour

The degree of change varies depending on the severity and location of the tear and how quickly treatment is started.

Types of Biceps Tendon Tears

Biceps tendon tears are classified in different ways to help determine the most suitable treatment.

First: Based on the Location of the Tear

1️⃣ Shoulder Tear (Proximal Tendon Tear)

This is the most common type and occurs where the tendon attaches to the shoulder joint.

Often linked to aging or repetitive strain
May not always require surgery

2️⃣ Elbow Tear (Distal Tendon Tear)

Less common but more serious.

Significantly affects arm strength and movement
Usually requires surgery to restore normal function

Second: Based on Severity

1️⃣ Partial Tear

Only part of the tendon is damaged
Symptoms are usually milder
May be treated with rest and physical therapy

2️⃣ Complete Tear

The tendon is fully detached
Causes severe weakness and visible muscle deformity
Often requires surgery, especially if located near the elbow

Third: Based on How the Injury Occurs

1️⃣ Acute (Sudden) Tear

Happens suddenly
Usually caused by lifting heavy objects or violent movement
Often accompanied by severe pain and a popping sound

2️⃣ Chronic (Gradual) Tear

Develops gradually over time
Caused by repetitive stress or overuse
Starts with mild pain that worsens over time and may progress to a complete tear if ignored

Causes of a Biceps Tendon Tear

A biceps tendon tear usually occurs due to factors that weaken the tendon or place sudden excessive stress on it.

⚡ 1. Sudden Exertion or Heavy Lifting

One of the most common causes, especially when the load exceeds the muscle’s capacity.

Examples include:

Suddenly lifting heavy weights
Pulling a heavy object forcefully
Trying to stop a heavy object from falling

These movements place direct stress on the tendon and may cause it to tear instantly.

⚡ 2. Incorrect Exercise Technique

Poor exercise form increases the risk of injury.

Examples:

Using weights heavier than one’s ability
Skipping warm-up exercises
Excessive repetitive training without rest

Over time, this can strain and weaken the tendon.

⚡ 3. Age-Related Tendon Weakness

As people age, tendons naturally lose flexibility and strength.

This makes them:

Less able to tolerate stress
More prone to tearing, even with minor effort

⚡ 4. Repetitive Stress

Repeated use of the arm in the same motions can gradually wear down the tendon.

Examples:

Repeated pulling or lifting
Heavy manual labor
Intense daily workouts

This wear and tear may eventually result in a partial or complete rupture.

⚡ 5. Direct Injuries

The tendon may tear due to sudden trauma to the arm.

Examples:

Falling on the arm
Receiving a strong blow to the shoulder or elbow

⚡ 6. Certain Medical Conditions and Medications

Some health conditions and medications can weaken tendons and increase the risk of tearing.

Examples:

Chronic tendon inflammation
Long-term corticosteroid use
Diabetes mellitus

Seventh: Smoking

Smoking negatively affects tissue nutrition and healing.

It:

Reduces blood flow to the tendons
Weakens the tendons’ ability to heal
Increases the risk of tendon tears

Where Does a Biceps Tendon Tear Occur?

A biceps tendon tear can occur in more than one location in the arm because the biceps muscle is connected to bones through tendons in two main areas: the shoulder and the elbow. The severity and impact of the injury vary depending on the location of the tear.

First: At the Shoulder (Upper Part)

This is the most common site for a biceps tendon tear.

It occurs in the tendon connecting the muscle to the shoulder joint
It most commonly affects the long head tendon

Main Causes:

Repetitive stress on the shoulder
Aging and tendon degeneration
Chronic shoulder inflammation

Important Note:

In many cases, especially with partial tears, this type of injury can be managed without surgery using conservative treatment.

Second: At the Elbow (Lower Part)

This type is less common but usually more serious than shoulder tears.

It occurs in the tendon connecting the muscle to the forearm bone
It directly affects arm strength and rotational movement

Main Causes:

Suddenly lifting heavy objects
Forceful pulling or violent arm movement

⚠️ Important Note:
This type often causes significant weakness in the arm and commonly requires surgery to repair the tendon.

Symptoms of a Biceps Tendon Tear

Symptoms of a biceps tendon tear often appear suddenly and clearly, although their severity depends on whether the tear is partial or complete and where it occurs.

First: Sudden Sharp Pain

Sudden pain is usually the first and most important symptom.

It occurs quickly during movement or heavy lifting
Pain appears in:
- The shoulder if the upper tendon is torn
- The elbow if the lower tendon is torn

The pain may also feel as if something “snapped” inside the arm.

Second: A Popping Sound

In some cases, especially complete tears:

The patient may hear or feel a noticeable “pop”
This is a common sign of tendon rupture

Third: Weakness in the Arm

Soon after the injury:

Difficulty bending the arm
Weak grip or lifting ability
Difficulty rotating the forearm or opening doors

Weakness is usually more noticeable in severe or complete tears.

Fourth: Swelling and Bruising

Shortly after the injury:

Swelling may appear around the shoulder or elbow
Blue or purple bruising may develop

This happens because of bleeding into the surrounding tissues after the tendon tears.

Fifth: Change in Muscle Shape

This is an important sign of a complete tear.

A visible bulge or “ball-like” appearance may form in the arm
This occurs because the muscle retracts after the tendon disconnects

Sixth: Gradual Loss of Function

In partial tears:

Pain may be milder
But persistent weakness remains
Discomfort appears during arm use

Seventh: Difficulty Moving the Arm

Reduced range of motion
Feeling of stiffness or muscle tightness
Difficulty performing normal daily activities

⚠️ When Should You See a Doctor Immediately?

You should seek medical attention urgently if you experience:

Sudden severe pain
A popping sound during injury
Significant arm weakness
Visible change in muscle shape
Difficulty using the arm normally

Diagnosis of a Biceps Tendon Tear

Diagnosing a biceps tendon tear depends on combining a clinical examination with imaging tests to determine the exact location and severity of the injury.

First: Clinical Examination (Main Step)

The doctor begins by taking a detailed medical history, including questions about:

Symptoms such as:

Sudden arm pain
Hearing a “pop” during the injury
Weakness in the arm

Cause of the injury:

Lifting heavy weights
Sudden or forceful movement

During the Physical Examination

The doctor will:

Examine the shape of the muscle for bulging or deformity
Assess muscle strength and arm movement
Check the range of motion in the shoulder or elbow

In complete tears, diagnosis may sometimes be obvious from the physical exam alone.

Functional Tests for the Biceps

The doctor may also perform special tests, such as:

Resisted elbow flexion test
Forearm rotation test (Supination test)

Severe pain or marked weakness during these tests may indicate a tendon tear.

Second: Imaging Tests

1. Ultrasound

Directly shows the condition of the tendon
Helps determine whether the tear is partial or complete
Quick, simple, and cost-effective

2. Magnetic Resonance Imaging (MRI)

MRI is considered the most accurate diagnostic tool.

It clearly shows:

The exact location of the tear
The severity of the injury
Any additional shoulder or elbow injuries

It is commonly used in unclear cases or before surgery.

3. X-ray

An X-ray does not show the tendon tear itself, but it helps rule out:

Bone fractures
Associated bone problems

⚠️ When Should Medical Tests Be Done Immediately?

You should see a doctor and undergo medical evaluation immediately if you experience:

Sudden and severe pain
A popping sound during the injury
Noticeable weakness in the arm
A visible change in the shape of the muscle
Difficulty using the arm normally

⚠️ Complications of a Biceps Tendon Tear

The complications of a biceps tendon tear vary depending on the severity and location of the injury, as well as how quickly it is diagnosed and treated. If the condition is neglected or treatment is delayed, it can significantly affect the strength and function of the arm.

First: Permanent Weakness in Arm Strength

This is one of the most common complications, especially in complete tears.

It may cause:

Difficulty bending the arm
Weakness when lifting or carrying objects
Reduced ability to rotate the forearm (such as opening doors or using tools)

This weakness is usually more noticeable in distal biceps tendon tears near the elbow.

Second: Partial Loss of Muscle Function

Even after treatment, the muscle may not fully regain its original performance in some cases, especially:

Complete tears
Delayed treatment

This may lead to a permanent reduction in strength.

Third: Muscle Deformity (Popeye Deformity)

A condition known as “Popeye deformity” may occur.

It includes:

A noticeable bulge in the muscle
Change in the normal shape of the arm
Retraction of the muscle upward in the arm

This is most commonly seen in complete tears near the shoulder.

Fourth: Chronic Pain

Pain may continue for a long time after the injury.

Shoulder or elbow pain
Pain that worsens with movement or physical effort

Fifth: Joint Stiffness and Limited Movement

Difficulty fully straightening or bending the arm
Reduced normal range of motion
Feeling of tightness or stiffness

Sixth: Increased Risk of Other Injuries

Weakness in the injured muscle may lead to:

Extra stress on nearby muscles and joints
Increased risk of additional shoulder or arm injuries

Seventh: Failure of Conservative Treatment or Need for Surgery

In some cases:

Physical therapy alone may not be enough
Surgery may not completely restore normal function

Eighth: Post-Surgical Complications

After surgery, some complications may occur, such as:

Surgical site infection
Joint stiffness
Persistent weakness
Problems with tendon healing

Surgical Treatment of Biceps Tendon Tears and Procedure Types

The surgical treatment of a biceps tendon tear depends on:

The location of the tear (shoulder or elbow)
The severity of the injury
The patient’s age and activity level

Below are the main surgical procedures and how they are performed.

First: Surgical Procedures for Shoulder Biceps Tendon Tears

1. Tenotomy

Tenotomy is one of the simplest surgical procedures used to treat biceps tendon tears in the shoulder.

Procedure:

Usually performed arthroscopically
Small instruments are inserted through tiny incisions in the shoulder
The damaged tendon is cut and left without reattachment

Advantages:

Simple and quick procedure
Short recovery period
Suitable for older adults or non-athletes

⚠️ Disadvantages:

Mild change in muscle appearance may occur
Slight loss of arm strength in some cases

2. Tenodesis

This is considered the preferred option for younger and athletic patients.

Procedure:

Can be performed arthroscopically or through open surgery
The damaged portion of the tendon is removed
The healthy end is reattached to the humerus bone using:
- Surgical screws
- Or special fixation devices

Advantages:

Preserves the normal appearance of the muscle
Better strength preservation compared to tenotomy

⏱️ Recovery:
Recovery takes longer than tenotomy, but long-term functional outcomes are usually better.

Second: Surgery for Distal Biceps Tendon Tears at the Elbow

3. Distal Biceps Repair

This is the main and most precise surgical procedure used for complete tears near the elbow.

Procedure:

Usually performed as open surgery
A small incision is made near the elbow
The torn tendon is identified
The tendon is pulled back to its normal position
It is reattached to the forearm bone using:
- Surgical screws
- Or modern fixation devices

Advantages:

Significant restoration of strength
Clear improvement in arm function

⚠️ Disadvantages:

Requires a longer rehabilitation period
More delicate and technically challenging than shoulder surgeries

Third: The Difference Between Arthroscopic Surgery and Open Surgery

Arthroscopic Surgery

Very small surgical incisions
Less pain after surgery
Faster recovery

This technique is most commonly used for shoulder injuries.

Open Surgery

A relatively larger surgical incision
Gives the surgeon a clearer view during tendon repair

This method is most commonly used for distal biceps tendon tears near the elbow.

Fourth: Stages After Surgery

First Stage

The arm is immobilized using a sling or brace
Arm movement is greatly restricted

Second Stage

Physical therapy begins gradually
Gentle joint movement is restored

Third Stage

Muscle strengthening exercises
Gradual return to normal activities

⚠️ When Is Surgery Recommended?

Surgery is usually recommended in the following situations:

Complete biceps tendon tear (especially near the elbow)
Severe weakness in arm strength
Need to fully restore arm function (such as in athletes)
Failure of conservative treatment (medications and physical therapy)

Treatment of Biceps Tendon Tears with Exercises

Exercise therapy is an essential part of recovery in cases of biceps tendon tears, especially in partial tears or after surgery. The goal is to gradually restore movement and strength without overloading the injured tendon.

First Stage: Gentle Exercises (Weeks 1–2)

Range of Motion Exercises

1. Gentle Elbow Movement

Slowly bend and straighten the elbow
Without resistance
Repeat 10–15 times daily

2. Forearm Rotation

Rotate the hand inward and outward (palm up and down)
Move slowly and without pain

Goal of This Stage

To prevent joint stiffness and maintain flexibility.

Second Stage: Light Exercises (Weeks 2–6)

Isometric Exercises

1. Contracting the Biceps Without Movement

Bend the elbow at a 90-degree angle
Tighten the muscle for 5–10 seconds
Repeat 10 times

2. Gentle Wall Press

Place the hand against a wall and press without movement
Hold for 5 seconds

Goal

To activate the muscle without placing excessive stress on the tendon.

Third Stage: Light Strengthening Exercises (Weeks 6–12)

1. Lifting Very Light Weights

Use a light dumbbell (0.5–1 kg)
Slowly bend the elbow with control
Perform 10–15 repetitions

2. Resistance Band Exercises

Use a light resistance band
Perform movements slowly and steadily

Goal

To gradually restore strength without straining the tendon.

Fourth Stage: Advanced Strengthening (After About 3 Months)

Gradual Return to Normal Activity

1. Biceps Curl Exercise

Gradually increase the weight
Maintain full control during movement

2. Light Pulling Exercises

Using gym machines
Start with low and progressive weights

Goal

To safely regain normal strength.

⚠️ Very Important Notes

Stop immediately if sharp pain occurs
Do not rush to increase weights
Gradual progression is the key to successful recovery
Exercises should preferably be performed under the supervision of a physical therapist
