Our Care

Surveys show that many of our patients wear their prosthesis at least eight hours per day -- about four times longer than the prosthetic industry average. This is a direct result of our holistic approach to prosthetic rehabilitation, which looks beyond the physical realm of limb loss to address the emotional, social and occupational aspects of a person’s life. Our high rate of successful prosthetic outcomes enables our patients to thrive!

Prosthetic Options

There are six prosthetic options available for people with an upper limb amputation or congenital limb difference. Since every person with upper limb loss presents a unique residual limb and has their own specific goals, we discuss and show all of these options to each patient, and then recommend the most appropriate choice.
