Are there free medical clinics in your area? That might be the place to start. They might not be able to use the specifically orthopedic hardware but who knows?
In Winston-Salem there is a free clinic that does have orthopedists. There may well be one in the Dallas area.
The other potential destination would be a mission hospital. The problem would be getting the heavy stuff shipped overseas. It is possible that the manufacturer of some of the hardware would be willing to take care of that process for you.
You might also see if an organization like "Mercy Ships", "Samaritan's Purse" or "MAP International" or "Doctors Without Borders" could put the equipment to good use in their overseas work. MAP International primarily focuses on supplying medication to overseas mission groups but they may be able to use hardware. I'd probably start with Mercy Ships since their ships serve as mobile operating facilities and they could possibly use a good bit of stuff. However, I do not know if they do orthopedic procedures on the ships.
Dad was an orthopedic surgeon. I know you're more in the medical end of things, but I thought maybe you could direct me someone who would put to good use some hardware I've been storing.
