Understanding Prosthetic Arms
Prosthetic arms are artificial limbs for those missing upper limbs. They help restore function and improve life quality. There are many types, each for different needs and amputation levels.
The level of amputation is key in choosing the right prosthetic arm. There are several levels of upper limb amputation:
| Amputation Level | Description |
|---|---|
| Partial Hand | Amputation of one or more fingers, but not the entire hand |
| Wrist Disarticulation | Amputation through the wrist joint |
| Transradial | Amputation below the elbow joint |
| Elbow Disarticulation | Amputation through the elbow joint |
| Transhumeral | Amputation above the elbow joint |
| Shoulder Disarticulation | Amputation through the shoulder joint |
| Forequarter | Amputation of the entire arm, including the shoulder blade and collarbone |
Modern prosthetic arms use advanced tech for better function and feel. Myoelectric prostheses control the arm with muscle signals. Microprocessor prosthetics adjust to movements and the environment.
A prosthetic arm has several parts. The socket fits over the limb, and the suspension system keeps it in place. The control system lets the user move the arm, and the terminal device is the hand or hook.
