Finger Extensor Tendon Injury: Comprehensive Care at Palms Physiotherapy & Allied Health

Understanding Finger Extensor Tendon Injuries

The extensor tendons are located on the back of your hand and fingers, extending from the forearm to the tips of the fingers. These tendons are vital for finger extension and precise hand movements.

Types of Finger Extensor Tendon Injuries

1. Partial Tear: The tendon is partially damaged but still intact.

2. Complete Rupture: The tendon is fully severed, often resulting in loss of finger extension.

3. Laceration: A cut or injury that severs the tendon.

4. Mallet Finger: An injury where the tendon at the fingertip is ruptured or stretched.

5. Boutonnière Deformity: A specific injury affecting the central slip of the extensor tendon.

Causes of Finger Extensor Tendon Injuries

• Trauma:

  • Direct impact or sharp objects can sever or damage the tendons.

• Overuse:

  • Repeated stress or strain on the extensor tendons, especially in activities requiring repetitive hand motions, can lead to injury.

• Sports Injuries:

  • High-impact sports or accidents during activities like cricket, basketball, or climbing often cause extensor tendon injuries.

• Degenerative Conditions:

  • Arthritis or other joint conditions can weaken the tendons, increasing susceptibility to injury.

Symptoms of Finger Extensor Tendon Injuries

• Loss of Movement: Inability to fully straighten one or more fingers.

• Pain and Swelling: Along the back of the hand or fingers.

• Visible Deformity: Fingers may appear bent or drooped.

• Tenderness: Over the affected tendon or joint.

• Wounds or Cuts: If the injury involves a laceration.

Diagnosing Finger Extensor Tendon Injuries

At Palms Physiotherapy & Allied Health, we use a thorough diagnostic approach:

1. Clinical Examination

• Assessment of finger movement, grip strength, and tendon functionality.

• Specific tests to identify tendon ruptures or malfunctions.

2. Imaging Tests

• Ultrasound or MRI: To assess the severity of tendon damage and associated injuries.

• X-Rays: To detect fractures or mallet finger deformities.

Treatment for Finger Extensor Tendon Injuries

Non-Surgical Treatment

For minor injuries or partial tears:

• Splinting: Immobilizing the affected finger to allow the tendon to heal.

• Pain Management: NSAIDs or other medications to reduce swelling and discomfort.

• Physiotherapy: Rehabilitation to restore tendon glide and finger extension.

Surgical Treatment

For severe injuries, including complete ruptures:

• Tendon Repair Surgery: Reattaching the ends of a torn tendon.

• Tendon Grafting: Using a graft if the tendon is extensively damaged.

Rehabilitation at Palms Physiotherapy & Allied Health

1. Immobilization Phase (0-4 Weeks)

• The injured finger is immobilized in a splint to facilitate healing.

• Adjacent joints are mobilized to prevent stiffness.

2. Early Motion Phase (4-8 Weeks)

• Guided exercises to improve tendon glide and flexibility.

• Gentle active and passive range-of-motion exercises.

3. Strengthening Phase (8-12 Weeks)

• Gradual strengthening exercises for grip and fine motor skills.

• Tailored programs for work or sport-specific tasks.

4. Functional Restoration (12 Weeks and Beyond)

• Advanced exercises to improve coordination and dexterity.

• Clearance for full return to activities based on recovery progress.

Complications to Monitor

• Tendon Adhesions: Scar tissue formation can restrict movement.

• Re-Rupture: Overuse or stress during the early healing stages.

• Joint Stiffness: Prolonged immobilization may lead to limited mobility.
