Shoulder Disarticulation Prosthesis
For amputation at the shoulder, requiring a full replacement of arm function.
Shoulder Disarticulation Prosthesis
A shoulder disarticulation prosthesis is fitted when the entire arm has been removed at the shoulder joint, with no upper arm bone remaining. This is one of the more complex upper-limb prosthetic levels, since the device needs to replace shoulder, elbow, wrist and hand function without any natural joint to build on.
Solutions at this level typically rely on a supportive shoulder-cap or chest-wall socket, and may combine passive positioning joints with body-powered or externally powered components, prioritised according to which functions matter most for the individual's daily activities.
This solution is often discussed for:
- Amputation at the shoulder joint with no remaining upper arm
- A need for a socket that anchors around the shoulder and chest wall
- Interest in prioritising specific functions (reach, grip, positioning) rather than full replication
- Consideration of lighter passive designs versus heavier powered systems

Fitting, training, adjustments and follow-up can be discussed as part of the individual pathway.

Common questions about shoulder disarticulation prosthesis.
Not entirely — at this level, most solutions prioritise specific useful functions (such as stabilising an object, or positioning a hand) rather than replicating the full range of natural arm movement. Goals are discussed individually to set realistic expectations.
It can be, since it replaces the most joints of any upper-limb level. Component choice, and sometimes a lighter passive design, can help balance function against comfortable, sustainable wear.
