Summary

The Veteran population is prone to foot and ankle maladies from common injuries such as sprains, and diseases such as ankle osteoarthritis (cartilage damage). More specific to Veterans are prior service injuries of the foot and ankle, which historically account for nearly a quarter of injuries received. These injuries include bone fractures and ligament damage. Some of these injuries may lead to poor ankle joint alignment, which over time could lead to osteoarthritis due to abnormal wear on a day to day basis. The goal of this proposal is to use a novel technology - biplane fluoroscopy, to study the movement of ankles which are misaligned in subjects with ankle osteoarthritis. This proposal will also benefit current diagnostic methods with additional information. Last, this proposal will test the effectiveness of a conservative treatment (modified shoe insoles) to correct or reduce the misalignment in ankles. This proposal will create evidence about: the nature of ankle osteoarthritis, the accuracy of diagnosing alignment, and conservative treatment for patients with ankle OA.

Conditions

  • Ankle Osteoarthritis

Interventions

OTHER

Dynamic 3D bone motion capture

Two x-ray systems will image the subjects ankle while they walk, allowing us to calculate ankle joint angle and alignment

DEVICE

wedged insole

medial or lateral wedge (appropriate for varus or valgus misalignment) will be applied during 1 data collection session to evaluate effect of wedging on misalignment
