Tendon Injuries

Tendon injuries can affect the hand, wrist, forearm, elbow, ankle, and other areas where muscles transmit force to bones. Depending on the injury, a tendon may be irritated, partially torn, completely ruptured, cut by a sharp object, or pulled away from its attachment.

Tendon injuries can cause pain, weakness, loss of movement, swelling, or inability to actively bend or straighten a joint. Accurate diagnosis is important because treatment differs greatly between overuse injuries, partial tears, complete ruptures, and open tendon lacerations.

What Is a Tendon?

A tendon is a strong band of connective tissue that connects muscle to bone.

When a muscle contracts, force is transmitted through the tendon to create movement at a joint.

Tendons must tolerate repeated loading while also gliding smoothly through surrounding tissues.

What Is a Tendon Injury?

A tendon injury can range from irritation and degeneration to partial tearing or complete disruption.

In the hand, tendons can also be completely divided by glass, knives, machinery, or other sharp objects.

The treatment depends on the tendon involved, the amount of damage, the mechanism of injury, and whether other structures such as nerves, blood vessels, joints, or bones are also injured.

What Types of Tendon Injuries Occur?

Common categories include:

• Tendinopathy
• Tenosynovitis
• Partial tendon tear
• Complete tendon rupture
• Open tendon laceration
• Avulsion injury
• Insertional tendon injury
• Chronic tendon degeneration

What Is Tendinopathy?

Tendinopathy is a broad term for a painful tendon condition usually related to repeated loading and structural changes within the tendon.

Chronic tendon problems are not always caused by active inflammation alone.

Progressive loading and rehabilitation are therefore often important parts of treatment.

What Is Tenosynovitis?

Tenosynovitis involves irritation or inflammation of the sheath surrounding a tendon.

Conditions such as De Quervain's tenosynovitis and some forms of trigger finger involve tendon sheath problems rather than a complete tendon rupture.

What Is a Partial Tendon Tear?

A partial tear means that some tendon fibers remain intact.

Patients may retain movement but experience pain, weakness, or reduced function.

Treatment depends on how much of the tendon is injured, whether the remaining tendon is stable, and which tendon is involved.

What Is a Complete Tendon Rupture?

A complete rupture occurs when the tendon is fully disrupted and can no longer effectively transmit muscle force.

The patient may suddenly lose a specific movement or notice a major decrease in strength.

Some complete ruptures require surgical repair, while others may occasionally be treated non-surgically depending on the tendon, patient, and functional demands.

What Is a Tendon Avulsion?

A tendon avulsion occurs when the tendon is pulled away from its attachment to bone.

Sometimes a small piece of bone is pulled away with the tendon.

Examples include mallet finger and jersey finger injuries.

What Causes Tendon Injuries?

Tendon injuries can occur because of:

• Sharp cuts
• Sports injuries
• Sudden forceful muscle contraction
• Direct trauma
• Falls
• Crush injuries
• Repetitive overuse
• Long-term tendon degeneration
• Previous tendon disease

Can a Tendon Rupture Without a Major Injury?

Yes. A tendon that has developed chronic degeneration can sometimes rupture during an ordinary movement or relatively minor load.

Age, previous tendon disease, systemic conditions, and certain medications can influence tendon quality.

What Are the Symptoms of a Tendon Injury?

Symptoms may include:

• Sudden or gradual pain
• Swelling
• Bruising
• Weakness
• Loss of active movement
• Difficulty gripping
• Difficulty bending or straightening a finger
• A snapping or popping sensation
• A visible change in tendon contour
• Loss of normal hand or limb function

Does Pain Always Mean the Tendon Is Torn?

No.

Tendon pain may come from overuse, tendinopathy, tendon sheath irritation, partial injury, or surrounding soft tissues.

A complete tendon rupture is more strongly suspected when there is sudden loss of active movement or marked weakness.

Can You Still Move With a Partial Tendon Tear?

Yes. Partial tears can preserve some movement because part of the tendon remains intact.

However, strength may be reduced and movement may be painful.

Continued ability to move does not completely exclude a meaningful tendon injury.

What Are Flexor Tendon Injuries?

Flexor tendons run along the palm side of the hand and fingers and allow the fingers and thumb to bend.

A deep cut across the palm or finger can partially or completely divide these tendons.

Significant injury may make it impossible to actively bend one or more finger joints.

What Are Extensor Tendon Injuries?

Extensor tendons run mainly along the back of the hand and fingers and allow the fingers and thumb to straighten.

Cuts, direct blows, and forced bending can injure these tendons.

Mallet finger is one example of a terminal extensor tendon injury.

Flexor Tendon Injury vs Extensor Tendon Injury

What Is Jersey Finger?

Jersey finger is an avulsion injury of the flexor digitorum profundus tendon.

It commonly occurs when an actively flexed finger is forcefully pulled straight, such as when grabbing an opponent's clothing during sport.

The patient may be unable to actively bend the fingertip.

What Is Mallet Finger?

Mallet finger involves injury to the terminal extensor tendon at the distal interphalangeal joint.

The fingertip droops and cannot be actively straightened.

The injury may be purely tendinous or may include a small avulsion fracture.

Can Tendon Injuries Occur With Nerve Damage?

Yes. Deep cuts in the hand and wrist can injure tendons, nerves, and blood vessels at the same time.

Numbness or altered sensation after a laceration may indicate an associated nerve injury.

Complex injuries require assessment of all structures rather than focusing only on the tendon.

Can Tendon Injuries Affect Blood Vessels?

The tendon itself does not normally cause vascular injury, but the same trauma can damage nearby arteries or veins.

A pale, cold, poorly perfused finger or persistent severe bleeding requires urgent assessment.

How Are Tendon Injuries Diagnosed?

Diagnosis begins with the mechanism of injury and a detailed physical examination.

The examination may assess:

• Active joint movement
• Passive joint movement
• Strength
• Tendon continuity
• Wound location
• Sensation
• Blood circulation
• Joint stability
• Associated fracture or ligament injury

Why Is Individual Tendon Testing Important?

Different tendons control different joints and movements.

In the fingers, each flexor and extensor component may need to be tested separately to determine which structure has been injured.

Simply asking the patient to open and close the hand may miss a partial or isolated tendon injury.

Can Ultrasound Diagnose Tendon Injuries?

Ultrasound can be useful for evaluating tendon continuity, partial tears, tendon movement, fluid, and some chronic tendon conditions.

Dynamic ultrasound can be especially helpful because the tendon can be observed during movement.

Is MRI Used for Tendon Injuries?

MRI can provide detailed information about tendon structure and surrounding tissues.

It may be useful for partial tears, chronic tendon problems, retracted ruptures, or complex injuries when the diagnosis is not clear clinically.

MRI is not required for every obvious open tendon laceration.

Are X-Rays Useful?

X-rays do not show most tendon tissue directly, but they can identify associated fractures, avulsion fragments, joint injuries, foreign bodies, and bony abnormalities.

They are particularly useful after trauma.

Does Every Tendon Injury Need Surgery?

No.

Tendinopathy, many partial tears, and selected closed injuries can often be treated non-surgically.

Complete lacerations, certain tendon avulsions, and functionally significant complete ruptures may require surgical repair.

Non-Surgical Treatment for Tendon Injuries

Should Tendon Injuries Be Completely Rested?

Not always.

Some acute repairs require strict protection, but prolonged unnecessary immobilization can contribute to stiffness and weakness.

The balance between protection and controlled movement depends on the tendon and injury pattern.

Are Exercises Helpful for Tendon Injuries?

Yes, but the timing and type of exercise matter.

Tendinopathy may benefit from progressive loading, while a newly repaired tendon requires a carefully controlled rehabilitation protocol.

Exercises that are appropriate for one tendon injury may be unsafe for another.

What Is Tendon Gliding?

Tendon-gliding exercises are designed to help tendons move relative to surrounding tissues.

They are commonly used during rehabilitation after selected hand tendon injuries and repairs.

The exercises must be timed carefully so that movement improves without placing excessive stress on the healing tendon.

What Is Early Controlled Motion?

Early controlled motion refers to carefully prescribed movement introduced during the healing period after selected tendon repairs.

The goal is to reduce adhesions and stiffness while protecting the repair from excessive force.

This is different from unrestricted normal use of the hand.

When Is Tendon Surgery Considered?

Surgery may be considered for:

• Complete tendon lacerations
• Selected complete ruptures
• Jersey finger
• Selected unstable avulsion injuries
• Retracted tendon injuries
• Open injuries with loss of tendon continuity
• Chronic tendon dysfunction causing significant functional loss
• Failed appropriate non-surgical treatment in selected conditions

How Is a Tendon Repaired?

Tendon repair involves identifying the damaged tendon ends and restoring continuity with specialized suturing techniques.

The repair must be strong enough to tolerate the planned rehabilitation while minimizing unnecessary bulk that could impair tendon gliding.

The exact technique depends on tendon size, location, injury type, and tissue quality.

Can a Tendon Be Repaired Directly?

Many recent tendon lacerations can be repaired directly when the tendon ends are healthy and can be brought together appropriately.

Chronic injuries or injuries with tissue loss may require more complex reconstruction.

What Is a Tendon Graft?

A tendon graft uses tendon tissue to bridge a gap when direct repair is not possible.

It may be considered in chronic injuries, large defects, or situations where the original tendon is no longer suitable for direct repair.

What Is a Tendon Transfer?

A tendon transfer redirects a functioning muscle-tendon unit to restore a movement that has been lost.

It may be considered when the original tendon cannot be reconstructed successfully or when muscle function has been lost because of nerve injury.

Tendon transfer redistributes existing strength rather than creating new muscle power.

What Is Tenolysis?

Tenolysis is a secondary procedure used to release scar tissue that prevents a healed tendon from gliding normally.

It is considered only after the tendon has healed sufficiently and when passive joint movement is better than active movement because of adhesions.

Why Do Tendon Adhesions Occur?

Tendons heal by forming scar tissue.

In some cases, the tendon becomes attached to surrounding tissues and cannot glide freely.

The risk is particularly relevant after complex hand trauma, crush injuries, fractures, infection, and prolonged immobilization.

Can a Repaired Tendon Rupture Again?

Yes.

A healing tendon is weaker than a normal tendon for a period of time.

Excessive force, premature unrestricted activity, poor tissue quality, infection, or severe original trauma can contribute to re-rupture.

What Are the Risks of Tendon Surgery?

Possible complications include:

• Infection
• Wound-healing problems
• Tendon adhesions
• Joint stiffness
• Re-rupture
• Persistent weakness
• Loss of motion
• Scar sensitivity
• Nerve injury
• Need for secondary surgery

Why Is Hand Therapy Important After Tendon Repair?

Hand therapy helps protect the repair while gradually restoring tendon glide, joint motion, strength, and function.

Too little movement can increase stiffness and adhesions, while too much force too early can damage the repair.

For this reason, rehabilitation should follow the specific surgical protocol.

How Long Does Tendon Healing Take?

Tendon healing occurs gradually over weeks and continues to remodel for months.

The time required before stronger loading is allowed depends on the tendon, repair technique, tissue quality, and associated injuries.

Skin healing does not mean that the tendon has regained normal strength.

When Can You Return to Work After a Tendon Injury?

Return to work depends on the tendon involved and occupational demands.

Light desk work may be possible earlier than heavy manual work involving forceful gripping, lifting, machinery, or repetitive hand use.

A fixed timetable is not appropriate for every tendon injury.

When Can You Return to Sports?

Return to sport should be based on healing, strength, range of motion, tendon function, and the risk of repeat injury.

Rehabilitation after a repaired tendon is typically more cautious than after a mild overuse injury.

Can Tendon Injuries Become Chronic?

Yes. Untreated partial tears, persistent tendinopathy, tendon adhesions, missed ruptures, and delayed diagnosis can lead to long-term weakness or loss of motion.

Chronic injuries may require more complex reconstruction than recent injuries.

Can an Old Tendon Injury Still Be Treated?

Yes.

Treatment options may still be available, but direct repair may become more difficult as the tendon retracts, scars, or degenerates.

Tendon grafting, tendon transfer, tenolysis, or joint procedures may be considered depending on the remaining function.

When Does a Tendon Injury Require Urgent Evaluation?

Prompt assessment is especially important when there is:

• A deep cut over the hand, wrist, or finger
• Sudden loss of active finger movement
• Inability to bend or straighten a joint
• An open wound with visible tendon
• Severe bleeding
• Numbness after a laceration
• A pale or cold finger
• Partial or complete amputation
• Open fracture
• Significant contamination

What Should You Do After a Deep Hand Cut?

A deep hand or finger cut should not be judged only by its size.

Even a relatively small wound can completely divide a tendon or nerve beneath the skin.

If movement, sensation, or circulation has changed, the injury should be assessed promptly.

Tendon Injury Treatment in Antalya

Tendon injury treatment should begin with determining whether the problem is an overuse condition, partial tear, complete rupture, open laceration, or avulsion injury.

Many overuse conditions and selected partial injuries can be treated with activity modification, splinting, rehabilitation, and progressive tendon loading. Complete tendon lacerations and selected ruptures may require surgical repair.

Complex hand injuries may involve tendons together with nerves, blood vessels, fractures, and joints. In these cases, treatment planning should address the entire injury rather than the tendon alone.

Frequently Asked Questions About Tendon Injuries

What is a tendon injury?

A tendon injury can involve irritation, degeneration, partial tearing, complete rupture, laceration, or avulsion from bone.

How do I know if a tendon is completely cut?

Sudden inability to actively perform the movement controlled by that tendon strongly suggests a major injury, but examination is required to confirm the diagnosis.

Can a partially torn tendon heal without surgery?

Some partial tendon injuries can heal with appropriate protection and rehabilitation, depending on the tendon, tear size, stability, and functional demands.

Does every tendon rupture need surgery?

No. Treatment varies by tendon and patient. Some ruptures are treated non-surgically, while others have better functional indications for repair.

What is the difference between a flexor and extensor tendon injury?

Flexor tendon injuries usually impair bending, while extensor tendon injuries usually impair straightening.

Can a small cut damage a tendon?

Yes. A small skin wound can still extend deeply enough to partially or completely divide a tendon.

Why is rehabilitation important after tendon repair?

Rehabilitation helps restore tendon gliding and joint motion while protecting the healing repair from excessive force.

Can a repaired tendon rupture again?

Yes. Re-rupture is possible, particularly if excessive force is applied before sufficient healing has occurred.

What are tendon adhesions?

Tendon adhesions are scar connections between the tendon and surrounding tissues that restrict normal gliding and active movement.

Can an old tendon injury still be reconstructed?

Yes. Chronic injuries may still be treated with tendon grafting, tendon transfer, tenolysis, or other reconstructive procedures depending on the remaining anatomy and function.
