About Us

The XLEG is a crutch alternative for persons required to be non-weight-bearing.

This device allows persons to easily and safely perform everyday tasks that have been difficult, painful, and at times not possible with existing crutches or crutch alternatives. There are functional and medical advantages to using the XLEG that provide a vast improvement in the quality of life and reduce the personal cost due to injury.



In January 2015, I was in a car accident that shattered my tibia and fibula. Since the accident, I have been on and off crutches as a result of 13 surgeries including 2 failed bone grafts due to bone infection. I tried every crutch or crutch alternative without finding a device that gave me the mobility and versatility that I wanted. So… I designed and built it.
