Amputation/Phantom Pains

What Are Amputation and Phantom Pains?

Amputation refers to the surgical removal of a limb or part of a limb due to trauma, infection, cancer, or other medical conditions. While the procedure itself addresses the underlying condition, many individuals experience phantom pain, a phenomenon where pain or discomfort is felt in the part of the limb that has been removed. Phantom pain is not imaginary, it is a real sensation caused by complex interactions in the nervous system, including the brain and spinal cord.

Types of Amputation and Phantom Pains

Amputation and phantom pain experiences vary depending on the type of amputation and the individual’s circumstances. Common types include:

Amputations: Amputations can be classified based on the affected limb or the level of removal:

• Upper Limb Amputation: Includes removal of fingers, hands, or arms. Phantom sensations in these cases may involve tingling, itching, or pain in the missing limb.

• Lower Limb Amputation: Commonly involves removal of toes, feet, or legs. Phantom pain often manifests as cramping, burning, or shooting sensations in the missing limb.

• Partial Amputation: Involves the removal of a portion of a limb, such as part of a foot or hand. Phantom pain may still occur in the part that was removed.

Phantom Pain Types: Phantom pain can differ in intensity and type. Common forms include:

• Phantom Limb Pain: Painful sensations that feel like they are coming from the missing limb.

• Phantom Sensations: Non-painful feelings, such as tingling, warmth, or cold, in the missing limb.

• Residual Limb Pain: Pain felt in the remaining part of the amputated limb, often caused by scar tissue, nerve irritation, or poorly fitting prosthetics.

Causes and Symptoms of Phantom Pains

Causes: Phantom pain is believed to result from changes in the nervous system following amputation. Possible mechanisms include:

• Neurological Reorganisation: The brain’s sensory map adapts to the loss of the limb, which can sometimes result in misinterpreted pain signals.

• Nerve Damage: Nerves severed during the amputation may become overactive, sending pain signals to the brain.

• Psychological Factors: Emotional stress or trauma associated with the amputation may exacerbate phantom pain.

Symptoms: Symptoms of phantom pain vary but commonly include:

• Burning, stabbing, or shooting pain in the area of the missing limb.

• Cramping or aching sensations.

• Tingling, pins-and-needles feelings, or numbness.

• Pain that worsens with stress, weather changes, or certain movements.

Diagnosis and Treatment Options

Diagnosis: Diagnosing phantom pain involves a thorough evaluation to rule out other conditions, such as residual limb pain or infections. Diagnostic steps may include:

• Medical History and Physical Examination: To assess symptoms and identify any contributing factors.

• Imaging Studies: X-rays or MRI may be used to check for residual limb issues, such as infections or nerve damage.

• Nerve Function Tests: Electromyography (EMG) may help evaluate nerve activity in the remaining limb.

Treatment: Treating phantom pain typically involves a combination of approaches tailored to the individual. Options include:

• Medications:

  • Pain relievers, such as paracetamol or ibuprofen.

  • Antidepressants or anticonvulsants to address nerve pain.

  • Local anaesthetics or nerve-blocking injections for severe cases.

• Therapies and Interventions:

  • Mirror Therapy: Using a mirror to create the illusion of the missing limb, helping retrain the brain and reduce pain.

  • Desensitisation Techniques: Massaging or applying different textures to the residual limb to reduce nerve sensitivity.

  • Transcutaneous Electrical Nerve Stimulation (TENS): Electrical stimulation applied to the residual limb to block pain signals.

  • Physical Therapy: Exercises to strengthen the residual limb and improve mobility with prosthetics.

• Surgical Options:

  • Targeted Muscle Reinnervation (TMR): A procedure that reroutes severed nerves to remaining muscles, reducing pain.

  • Revision Surgery: In cases of severe residual limb pain, surgery may help address scar tissue or neuroma (nerve growths).

• Alternative Therapies:

  • Acupuncture or biofeedback to manage pain and stress.

  • Mindfulness-based stress reduction or cognitive behavioural therapy (CBT) to address the psychological impact of phantom pain.
