Who Needs Artificial Arms?
Every year, thousands of people face life-changing limb loss due to accidents or medical conditions. Prosthetic arms restore functionality, whether from trauma, disease, or birth differences. The right solution depends on the cause and level of amputation.
Common Causes of Arm Amputation
In India, 67% of amputations result from trauma, like industrial accidents (38%) or vehicular crashes (29%)6. Vascular diseases, such as diabetes, account for 22% of cases7. Congenital conditions like ulnar clubhand (1 in 10,000 births) also require prosthetic support7.
Levels of Upper Limb Amputation
Prosthetics are customized to the amputation level:
- Transradial: Below the elbow, preserving some forearm movement7.
- Transhumeral: Above the elbow, needing advanced socket designs (e.g., PrimeCare’s rotator cuff integration)6.
- Shoulder disarticulation or forequarter: Entire shoulder removal, requiring specialized prosthetics7.
“Surgical preservation of muscle sites enables better myoelectric control, critical for high-functioning prosthetics.”
Surgeons now prioritize nerve preservation during amputation, enhancing future prosthetic adaptability. This progress ensures users regain precision in daily tasks6.
