Biomechanical and Morphological Characterization of PTTD

X-rays of the ankle; anterior-posterior, lateral, Mortise view and hindfoot alignment view. Standard weight bearing x-rays of the foot; anterior-posterior, lateral and oblique view.

Ultrasound of the posterior tibial tendon to see if there is an irritation, elongation or rupture.

MRI when ultrasound is not conclusive to identify an irritation, elongation or rupture of the posterior tibial tendon.

CT-scan to identify arthritis of the tibial-talar, subtalar and/or Chopart joints.

This lab is equipped with a 10-meter walkway surrounded by a passive optoelectronic motion analysis system consisting of 10 cameras to track the motion of markers. In the middle of the walkway, a force plate is integrated, with a pressure plate placed on top.
