Ankle Disarticulation (Syme's) Prosthesis
Ankle disarticulation prosthetics preserving full lower-leg length.
Ankle Disarticulation (Syme's) Prosthesis
A Syme's (ankle disarticulation) prosthesis is used when the amputation occurs through the ankle joint, preserving the full length of the tibia and fibula. This longer residual limb offers a good weight-bearing surface and strong leverage, which can be an advantage for balance and control compared with a higher below-knee amputation.
Because the leg length is close to natural, prosthetic sockets and foot components need to be designed carefully to restore equal leg length while accommodating the shape of the residual limb near the ankle.
This solution is often discussed for:
- Amputation through the ankle joint with the tibia and fibula preserved
- A desire for strong end-weight-bearing capability
- A residual limb suited to a bulb-shaped or expandable socket design
- Interest in maintaining a leg length close to the sound side
Start with the person's needs, goals, existing situation and practical requirements.

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

Matching prosthetic leg length to the remaining sound limb
Socket design to accommodate the distal limb shape for weight-bearing
Foot and ankle component selection for the intended activity level
Skin tolerance at the weight-bearing end of the residual limb
Footwear and cosmetic shell considerations for a natural appearance
Common questions about ankle disarticulation (syme's) prosthesis.
Often yes — this level is known for good end-weight-bearing capacity, which some people find comfortable for standing and short-distance walking without a shoe on the prosthetic side. This is confirmed individually during assessment.
The socket can be slightly bulkier around the ankle area to accommodate the distal limb shape, though component and shell design can help keep the overall profile as streamlined as possible.
