Finger Extension Contracture

Finger extension contracture is a condition where one or more fingers become bent and difficult to straighten. In this article, we will break down the types, causes, symptoms, diagnostic tests, treatments, and drugs related to finger extension contracture in simple, easy-to-understand language.

Types of Finger Extension Contracture:

Finger extension contracture can be categorized into different types based on its causes:

  1. Traumatic Finger Extension Contracture: Caused by injuries or accidents.
  2. Dupuytren’s Contracture: Develops gradually, often affecting the ring and little fingers.
  3. Volkmann’s Contracture: Results from reduced blood flow to the forearm muscles.
  4. Arthritis-Related Contracture: Occurs in individuals with arthritis, leading to joint deformities.

Causes of Finger Extension Contracture

  1. Injury: A sudden trauma or accident can damage finger tendons.
  2. Scar Tissue: Scarring from surgery or wounds can restrict finger movement.
  3. Genetics: Some people have a genetic predisposition to develop finger contractures.

  12. Tumor Growth: Tumors in the hand can affect finger function.
  13. Tendonitis: Inflammation of finger tendons can restrict movement.
  14. Stroke: Brain injuries from strokes can affect hand function.
  15. Cerebral Palsy: A neurological condition that can lead to contractures.
  16. Muscular Dystrophy: A genetic disorder that weakens muscles.
  17. Spinal Cord Injuries: Damage to the spinal cord can affect hand control.
  18. Inflammatory Diseases: Conditions like lupus can cause joint problems.
  19. Contracture Diseases: Specific conditions, like Dupuytren’s, can lead to contractures.
  20. Medications: Certain drugs may contribute to finger stiffness.

  13. Contracted Palm: In severe cases, the palm may also become affected.
  14. Discomfort during Rest: Fingers may ache even when not in use.
  15. Skin Changes: Skin may become tight and shiny over contracted areas.
  16. Nodules or Lumps: These may form under the skin in some types of contracture.
  17. Cold Sensation: Reduced blood flow can make fingers feel cold.
  18. Finger Instability: The finger(s) may feel unstable.
  19. Limited Dexterity: Difficulty performing precise tasks.
  20. Emotional Impact: Contracture can affect self-esteem and mental well-being.

Diagnostic Tests for Finger Extension Contracture

  1. Physical Examination: A doctor will assess finger mobility and check for deformities.

  9. Arthroscopy: Minimally invasive procedure to view joint interiors.
  10. Biopsy: Removing a small tissue sample for analysis in certain cases.
  11. Nerve Block: A diagnostic tool to assess pain sources.
  12. Doppler Ultrasound: To assess blood flow in cases of Volkmann’s contracture.
  13. Skin Biopsy: Can be used in some forms of contracture.
  14. Joint Aspiration: Removing fluid from a swollen joint for analysis.
  15. Tensile Testing: Measures finger tendon strength.
  16. Grip Strength Test: Evaluates hand strength using a dynamometer.
  17. Cold Sensitivity Test: Assessing finger response to cold stimuli.
  18. Nerve Conduction Velocity Test: Measures nerve signal speed.
