Frequently Asked Questions

Q: What is a prosthetic limb?
A: A prosthetic limb is an artificial device that replaces a missing arm or leg to restore function and improve mobility.

Q: How soon after amputation can I get a prosthetic?
A: Typically, you can be fitted 8–12 weeks after surgery, once the wound has healed and swelling is reduced, but timelines vary based on individual recovery.

Q: Will I be able to walk normally with a prosthetic leg?
A: Many people walk well with a prosthesis after physical therapy and training, though the gait may differ slightly from natural walking.

Q: Do prosthetics hurt to wear?
A: A properly fitted prosthesis should not hurt. Initial discomfort is common, but ongoing pain may indicate a poor fit or skin issue and should be addressed.

Q: How much do prosthetics cost?
A: Costs vary widely depending on the type and technology involved—basic limbs may cost $5,000–$10,000, while high-tech or custom prosthetics can exceed $50,000.

Q: Are prosthetics covered by insurance?
A: Many health insurance plans (including Medicare) cover prosthetic limbs partially or fully, though policies differ; always check with your provider.

Q: How long does a prosthetic last?
A: Most prosthetic limbs last 3–5 years, but the socket (the part that fits the residual limb) may need adjustments or replacements sooner.

Q: Can I do sports or swim with a prosthetic?
A: Yes—there are specialized prosthetics designed for running, swimming, biking, and more. Talk to your provider about activity-specific options.

Q: How do I care for my prosthetic limb?
A: Daily cleaning of the socket, checking for wear, and storing it in a dry place are essential. Regular follow-up with your prosthetist ensures it stays functional and comfortable.

Q: What’s the difference between a prosthetist and an orthotist?
A: A prosthetist specializes in designing and fitting artificial limbs, while an orthotist creates braces and supports for existing limbs.

Q: What are prosthetic socks, liners, and sleeves?

A:

Socks: Worn over the residual limb to manage volume changes and improve prosthetic fit.

Liners: A soft cushioning layer worn next to the skin, often made of silicone, gel, or polyurethane, to reduce friction and protect the limb.

Sleeves: Worn over the top of the prosthesis and thigh to create a suction seal or vacuum suspension system.

Q: How do I know when to add or remove prosthetic socks?

A: If the prosthesis feels too loose, add a sock ply; if it’s too tight, reduce sock ply. Limb volume changes throughout the day, so frequent adjustments are normal.

Q: What are “sock ply” levels?

A: Sock “ply” refers to thickness—common plies are 1, 3, and 5. You can layer multiple socks to achieve the desired fit.

Q: How often should I change my liner or sleeve?

A: Most liners and sleeves last 3 to 6 months with daily use, but this varies with activity level and hygiene. Signs of wear like tears or loss of suction mean it’s time to replace them.

Q: How do I clean prosthetic liners and sleeves?

A: Wash daily with mild soap and warm water, then air dry. Avoid hot water, strong detergents, or direct sunlight.

Q: Can I wear a sock under a gel or silicone liner?

A: Usually no—liners are designed to go directly against the skin. However, some users with skin sensitivities may be prescribed specialty interface socks.

Q: What if I develop skin irritation under my liner or sleeve?

A: This could be due to sweat, friction, or improper fit. Clean the area, let it breathe, and contact your prosthetist for adjustments if irritation persists.

Q: What types of prosthetic liners are available?

A:

Silicone: Durable, offers firm suspension

Gel (TPE): Softer and more cushioned

Urethane: Conforms well to limb shape, good for bony limbs

Q: What’s the role of a sleeve in a suction or vacuum system?

A: It helps seal the prosthetic socket to the limb, maintaining suspension and preventing air leaks in elevated vacuum systems.

Q: Can I wear regular socks instead of prosthetic socks?

A: No—prosthetic socks are made of specific materials (like CoolMax, wool, or Lycra blends) and designed for breathability, stretch, and uniform thickness.
