Tendon Lacerations: Causes, Diagnosis, Surgical Repair, and Recovery

Tendon lacerations are types of injuries which are quite common and can disrupt daily life, limit mobility, and cause long-term complications if not treated properly. The tendons in our body are fibrous tissues that connect muscles to bones and play a crucial role in movement. However, when a tendon is cut or torn, it can lead to pain, weakness, and loss of function. This article provides detailed information about tendon lacerations, their causes, diagnosis, surgical repair, and recovery process.

What Are Tendon Lacerations?

Tendon lacerations occur when a tendon is partially or completely severed, often due to trauma or injury. Tendon lacerations commonly occur in the tendons of the hands, fingers, wrists, and the Achilles tendon.

Common Causes

The most common causes of tendon lacerations include:

• Accidents: Cuts from knives, glass, or machinery.
• Sports Injuries: Sudden impacts, overuse, or improper technique while playing different types of sports.
• Animal Bites: Bites from dogs or cats can cause deep punctures in the skin and tendons leading to lacerations.
• Degenerative Conditions: Ageing, diabetes, or rheumatoid arthritis can cause weakened tendons that can result in lacerations.

Types of Tendon Injuries

• Partial Tears: The tendon is damaged but not completely severed.
• Complete Tears: The tendon is fully cut, requiring surgical repair.
• Avulsion Injuries: The tendon is torn away from the bone.

Symptoms of a Tendon Laceration

Recognising the signs of a tendon laceration is crucial for timely intervention and treatment. Tendon laceration symptoms include:

• Inability to Move: Difficulty or inability to move the affected joint or limb.
• Pain and Swelling: Sharp pain at the injury site, often accompanied by swelling or bruising.
• Visible Wound: A deep cut or gap in the skin where the tendon is located.
• Popping Sensation: A "popping" or snapping feeling at the time of injury.

If you experience any of these symptoms, it is important to seek medical attention immediately so that the injury can be treated and to prevent any further damage.

Diagnosis of Tendon Lacerations

A proper diagnosis of the tendon laceration by an orthopaedic specialist is crucial to determining the extent of the injury and the corresponding course of treatment. Diagnosis typically involves the following:

Physical Examination

The doctor carries out a physical exam as the first step to assess the range of motion, strength, and function of the affected area. He may ask you to perform specific movements to identify the damaged tendon.

Imaging Tests

The doctor may also order an imaging test to get a clear picture of the exact location and extent of damage. The imaging tests can include:

• X-rays: These are ordered to rule out bone fractures or dislocations.
• MRI: An MRI scan helps to visualise soft tissues like tendons and gives a clear image of the severity of the injury.
• Ultrasound: An ultrasound helps evaluate tendon movement and integrity in real time.

Treatment for Tendon Lacerations in Singapore

There are different tendon laceration treatments in Singapore. The effective treatment plan depends on factors such as the severity of the injury, the location of the tendon, and the patient’s overall health.

Non-Surgical Treatment

For partial tendon tears or minor injuries, doctors may take the conservative route that includes non-surgical options such as:

• Immobilisation: Using a splint or cast to keep the tendon in place while it heals.
• Physical Therapy: Gentle exercises to restore strength and flexibility in the affected joint and area.
• Medications: Anti-inflammatory drugs to reduce pain and swelling.

Surgery for Tendon Lacerations

The surgical treatment for tendon lacerations in Singapore is often recommended when the tendon tears are complete tears or severe lacerations. 

Tendon Repair Surgery: A Step-by-Step Guide

Before Surgery

• Consultation: Your doctor will explain the procedure, its related risks, and expected outcomes.
• Pre-Surgery Instructions: You may need to stop taking certain medications (e.g., blood thinners) and fast for several hours before the surgery.
• Anaesthesia: The surgery is typically performed under local, regional, or general anaesthesia. Your doctor will guide you regarding the type of anaesthesia according to your injury.

During Surgery

• Incision: The first step of the surgery is to make an incision to access the damaged tendon.
• Repair: The surgeon then stitches the torn ends of the tendon together using sutures. In some cases, a tendon graft may be needed if the tendon is severely damaged. The surgeon will take a healthy tendon from some other part of your body and replace the damaged tendon with a healthy one.
• Closure: Once the affected tendon has been repaired or replaced, the incision is closed with stitches or staples, and a bandage is applied.

After Surgery

• Immobilisation: After the surgical procedure, the affected area is immobilised with a splint or cast to protect the repaired tendon.
• Pain Management: Pain and swelling can be managed with medications and ice packs.
• Follow-Up Appointments: Your doctor will schedule regular check-ups to monitor healing and progress.

Recovery and Rehabilitation After Tendon Surgery

Recovery from tendon surgery is a gradual process that requires patience and dedication. You will need to take some immediate post-operative measures followed by physical therapy for long-term recovery and prevention.

Immediate Post-Surgery Care

• Wound Care: Keep the surgical site clean and dry to prevent infection.
• Rest: Avoid using the affected limb to allow the tendon to heal.
• Elevation: Elevate the injured area to reduce swelling.

Physical Therapy

• Early Mobilisation: Carry out gentle exercises to prevent stiffness and scarring.
• Strengthening Exercises: Gradually increase exercise intensity to restore strength and flexibility.
• Range of Motion: Incorporate stretching exercises into your regimen to improve mobility.

Long-Term Recovery

• Timeline: Full recovery can take 3–6 months or longer, depending on the severity of the injury.
• Lifestyle Adjustments: Avoid overusing the affected area to prevent re-injury.
• Follow-Up: Schedule regular visits to your doctor to monitor progress.

Potential Complications of Tendon Surgery

While tendon repair surgery is generally safe, there could be some potential complications, including:

• Infection: Redness or swelling at the surgical site, that may or may not be accompanied by a fever.
• Scarring: Adhesions that limit movement.
• Re-Rupture: The tendon tears again, often due to overuse or improper healing.
• Stiffness: Reduced range of motion in the affected joint.

If you notice any signs of complications, contact your doctor immediately.

Preventing Tendon Lacerations

While not all tendon injuries can be prevented, you can reduce your risk by:

• Wearing Protective Gear: Use gloves, pads, or braces during sports or high-risk activities.
• Using Proper Techniques: Handle sharp objects carefully and follow safety protocols at work.
• Strengthening Tendons: Keep doing regular exercises and stretching to improve tendon health.

Conclusion

Tendon lacerations are serious injuries that require prompt medical attention and often surgical intervention. With proper treatment and rehabilitation, most patients can regain full function and return to their daily activities. If you suspect a tendon injury, don’t delay—seek medical attention right away.
