Understanding Amputation: What, Why, and How

Amputation is a surgical procedure that involves the removal of an extremity, such as a limb, to save the rest of the body from harm. This drastic measure is usually taken when the affected limb poses a threat to the person’s life due to trauma, prolonged constriction, or a medical condition

Reasons for Amputation

The most common reason for amputation is poor circulation due to narrowed arteries, which can damage muscles and tissues in the limb. Other causes include:

– Severe injury or trauma
– Cancerous tumors in muscles or bones
– Blocked or decreased blood supply due to constricted blood vessels
– Chronic leg ulcers and septicemia
– Serious infections that don’t respond to treatment
– Neuroma, a condition where nerve tissue thickens
– Frostbite, which can constrict blood vessels

The Amputation Procedure

Amputation surgery is typically performed under general anesthesia, although spinal anesthesia may be recommended for lower limb amputations. The surgeon:

– Removes damaged tissue, retaining as much healthy tissue as possible
– Uses various methods to determine the extent of tissue removal, such as pulse proximity, skin temperature, and sensitivity to touch
– Removes affected tissues and crushed bones
– Smoothens uneven areas of the affected bone
– Seals nerves and blood vessels
– Shapes and seals the muscles of the remaining limb for prosthesis attachment

Post-Amputation Surgery

Recovery from amputation surgery depends on the extent of the problem, procedure, and anesthesia used. Hospital staff will:

– Change dressings and monitor wound healing
– Administer medications for pain and infection prevention
– Provide counseling to address emotional trauma
The healing process typically takes four to eight weeks. Patients may experience phantom limb pain, a condition where they feel pain in the amputated limb.

Rehabilitation and Recovery

Physical therapy begins soon after surgery, focusing on simple exercises and stretching. The process of fitting an artificial limb starts 10-14 days after surgery. Rehabilitation considers:

– Improving muscle control and strength
– Learning new techniques for daily activities
– Using and controlling artificial limbs and assistive devices
– Providing counseling and emotional support throughout the rehabilitation process

Diagnosis

AMD is diagnosed through a comprehensive eye exam, including:

– Dilating eye drops to widen the pupil
– Fluorescein angiography to detect abnormal blood vessels
– Optical coherence tomography (OCT) to scan the retina and macula
– Optical coherence tomography angiography (OCTA) to detect abnormal blood vessels without dye

Treatment

While AMD is not curable, some management options are available:

– Anti-angiogenic drugs to stop new blood vessel growth and block leaking
– Laser therapy to destroy actively growing new blood vessels
– Vitamin supplements like vitamins C and E, beta-carotene, and minerals like zinc and copper
– Eating a balanced diet rich in fruits, vegetables, and omega-3 fatty acids
