Wrist Disarticulation Prosthesis
For amputation at the wrist joint, preserving forearm rotation.
Wrist Disarticulation Prosthesis
A wrist disarticulation prosthesis is used when the amputation occurs at the wrist joint itself, with the forearm bones left intact. Retaining the full forearm length can preserve natural forearm rotation, which is a meaningful functional advantage compared with a higher-level amputation.
Because the residual limb is longer than in a typical transradial case, socket design and component selection need to account for limited space near the wrist while still accommodating a functional terminal device, whether body-powered, myoelectric or a hybrid system.
This solution is often discussed for:
- Amputation at or very near the wrist joint
- A residual limb with good forearm length and rotation
- A need to preserve natural pronation and supination for daily tasks
- Interest in either body-powered or myoelectric terminal devices

Available space at the wrist for socket and component fitting
How much natural forearm rotation is preserved and used functionally
Terminal device choice — hook, myoelectric hand or task-specific attachment
Socket comfort during repetitive forearm movement
Skin tolerance and sweating in the residual limb, especially with electrode-based systems
Common questions about wrist disarticulation prosthesis.
Even without the hand, an intact wrist and forearm allow natural rotation, which many prosthetic designs try to preserve or accommodate. This can make certain everyday movements feel more intuitive than with a higher-level amputation.
Often, yes, depending on available space and residual muscle signal quality. Whether a myoelectric, body-powered or hybrid option is suitable is assessed individually.
