History of Prosthetic Limbs

Prosthetic limbs have been around for 3000 years.

Typically made of iron or wood.Served no real purpose. Insertion was crude.Until recently, prosthetics utilized hooks.

Hook Hands

Hooked prosthetics are controlled manually.

Incorporate a pulling system.

Very limited in function.

National Health Service and built by Touch Bionics™
