What is a Transhumeral prosthesis?

A transhumeral prosthesis helps to replace the function of a missing anatomical segment(s) from below the shoulder to (and including) the hand. How it is powered. Type of control system for these prostheses are dependent on the needs, functions, and goals of each patient.

How do transhumeral prosthesis work?

Transhumeral prostheses are usually operated by two distinctly separate control cables (Fig 6B-18.). One cable serves both to flex the prosthetic elbow joint and to operate the terminal device. A second cable permits the amputee to lock and unlock the prosthetic elbow.

What is transradial amputation?

A transradial amputation is a surgical procedure in which the radius and ulna (bones of the lower arm) are cut, and the lower portion of these bones and the hand are removed from the body.

How does a myoelectric hand work?

A “myoelectric” arm is operated when electrodes pick up muscle (myo is from the Greek word for muscle) impulses from the residual limb. These muscle impulses (signals) are then translated into electrical signals that are sent to the electric hand to open or close it. A battery in the prosthesis provides the power.

How much does it cost for a prosthetic arm?

How much does a prosthetic arm or hand cost? Without insurance, you can expect to pay around $5,000 for a cosmetic prosthetic, up to $10,000 for a functional prosthetic with a hook, and between $20,000 to $100,000 for the latest myoelectric arm technology.

What are advantages of doing an elbow disarticulation instead of Transhumeral?

In children, transhumeral amputation results in a high incidence of bony overgrowth. An elbow disarticulation preserves the epiphysis, prevents bony overgrowth, and maintains growth potential; therefore, elbow disarticulation is the level of choice.

What is Transhumeral amputation?

Amputation through the arm, or transhumeral amputation, is defined as amputation at any level from the supracondylar region of the humerus distally to the level of the axillary fold proximally.

How long can you wear a prosthetic arm?

How often will I have to get my prosthesis replaced? That depends on your activity level and how well you take care of your prosthesis. A rule of thumb is from two to four years.
