Hello to the group,

Michelsen (JBJS, 1996) published an article titled "Motion of the Ankle in a
Simulated Supination-External Rotation Fracture Model" which utilized a
foot/ankle loading apparatus designed by Experimental Engineering (Little
Rock, AK). I have attempted to find that company but could find no listing
via phone/web. I was wondering if anyone was familiar with the company.
Perhaps they changed names/locales?

I was hoping to purchase an apparatus similar to that utilized by Michelsen
which has 3 mutually orthogonal potentiometers attached to a worm drive
mechanism. The worm drive translates the tibia (foot is upside down) while
an axial load is applied to the plantar surface. Angular motion is then
calculated from the potentiometers. I believe this apparatus was used in a
few studies that came from the Johns Hopkins lab in the mid-1990s.

I apologize for any lack of clarity in this email.

Thanks in advance for your assistance.

Kindest regards,

Andrew
