Amputation and Prosthesis Levels

The first factor in planning a prosthesis is the level of amputation. Even at the same level, residual limb length, skin and muscle condition, age and activity level can call for different solutions.

Lower limb levels

• Partial foot: Silicone prostheses or custom insoles for toe or forefoot loss.
• Below-knee (transtibial): The most common level. Because the natural knee is preserved, walking is usually easier to learn.
• Knee disarticulation: Offers a long residual limb and end-bearing capability. Requires dedicated knee systems.
• Above-knee (transfemoral): The choice of prosthetic knee is critical for safe walking.
• Hip disarticulation: The hip, knee and ankle joints are all replaced by the prosthesis.

Upper limb levels

• Finger and partial hand: Natural appearance is usually achieved with silicone prostheses.
• Wrist and forearm (transradial): Cosmetic, mechanical and myoelectric options can all be applied.
• Elbow and upper arm (transhumeral): Requires an elbow unit and a more extensive control system.
• Shoulder level: Requires a custom design and detailed planning.

To learn which options suit your level, bring your medical report to a consultation.
