Elbow Disarticulation Prosthesis
For amputation through the elbow joint, preserving full humeral length.
Elbow Disarticulation Prosthesis
An elbow disarticulation prosthesis is used when the amputation passes through the elbow joint rather than above or below it, leaving the full length of the upper arm bone intact. This preserves a longer lever arm and stronger rotational control at the shoulder than a higher transhumeral amputation, which can be an advantage for socket stability and control.
Because there is no natural elbow remaining, the prosthesis still needs a mechanical or externally powered elbow, but the longer, broader residual limb often allows for a more secure, self-suspending socket design.
This solution is often discussed for:
- Amputation directly through the elbow joint
- A residual limb with the full upper arm length preserved
- A need for stronger socket stability due to the longer residual limb
- Consideration of body-powered or externally powered elbow components

Socket design given the broader, longer residual limb shape
Elbow component choice — mechanical, hydraulic or myoelectric
Suspension approach, which can sometimes rely more on limb shape than harnessing
Coordinating elbow and terminal device function
Comfort and skin tolerance around the elbow region during extended wear
Common questions about elbow disarticulation prosthesis.
Yes, generally. A longer residual limb typically provides better leverage and rotational control, and can sometimes support a self-suspending socket that needs less external harnessing.
Yes — although the natural elbow joint is gone, the prosthesis still requires a mechanical or powered elbow component to bend and position the forearm and hand.
