An Evaluation Of Healthy Ankle Motion And Morphology

N/ACompletedNCT03619382

Paragon 2819 enrolled

Overview

Determine motion and morphology of the healthy ankle during simulated gait.

Healthy volunteers will undergo weight-bearing, cone beam CT scans of their foot/ankle during 3 phases of simulated gait. Motion and morphology of the foot and ankle will be quantified and analyzed.

Outcomes

Primary Outcomes

Relative rotations of bones

Determine relative tri-axial rotations between bones of the foot and ankle using reconstructed 3-dimensional computer models. All rotations will be measured in degrees (°).

Time frame: 1 day

Secondary Outcomes

Relative translations of bones

Determine relative multi-directional translation between bones of the foot and ankle using reconstructed 3-dimensional computer models. All translations will be measured in mm.

Time frame: 1 day

Morphology - size and shape of the bones of the foot and ankle

Evaluate the size and shape of the bones of the foot and ankle using reconstructed 3-dimensional computer models relative to height, weight, body mass index and gender. All distances will be measured in mm.

Time frame: 1 day
