General Questions

How long will the prosthesis/orthosis last due to growth of a child?

Children grow at very different rates.  When we design a pediatric prosthesis/orthosis for example, we keep in mind that our patient is actively growing.  It is our goal to design the device to last as long as possible, while not compromising it’s function. We recommend that children come in for regular visits if they are experiencing increased growth or noticing the device is getting tight or causing discomfort.

What do I do with an old prosthesis or orthosis?

United States federal regulations restrict the reuse of braces and prostheses regardless of condition because they are medical devices. However, we are pleased to accept donations for use in humanitarian trips we regularly take out of the country to provides these much needed used adaptive devices to individuals in developing nations.  If you would like to learn more please ask, we can discuss where we have been recently, plans for the near future, and how you can help.

Is the cost of my prosthesis/orthosis covered by insurance?

This depends on the type of insurance you have. As a free service to you our office staff will contact your insurer to help you determine what your policy covers, and explore other funding sources as needed.  In most cases the majority if not all of the cost of a prosthesis/orthosis is covered through traditional insurers.

What kind of warranty or guarantee does the prosthesis/orthosis have?

We warranty each new device against defects, workmanship and materials for a full 90 days from the day you receive your device. Any non-warranty claims will be evaluated on a case by case basis, and we provide a repair estimate prior to performing any repairs. Keep in mind that physical changes of a patient are not covered under this warranty (i.e., swelling, weight fluctuations) since we have no control over such matters.  Any non-warranty claims or physical changes can however be billed through insurance in most cases.



Below you will see some links to websites we believe are excellent resources for individuals who use a prosthesis or orthosis. Links are categorized according to their focus. They cover a wide range of topics from competitive sports to support services for people who have recently begun using a prosthesis/orthosis, or are having a difficult time with their adjustment.

Be sure to let us know if there are other sites you believe would benefit our patients. We are always on the lookout for great new resources.
