About

To study flexor tendon excursion in the hand after surgery by dynamic MRI

Full description

The study of the movement of the digital flexor tendon operated on MRI could lead to a better understanding of the biomechanics of this tendon after surgery, to objectively assess the repair of the tendon and the recovery of its mobility. The visualization of the aspect and the movement of this operated tendon would make it possible to adapt the rehabilitation for each patient and to prevent the occurrence of complications which limit functional recovery and source of handicap.

The analysis of the imaging in patients evolving would establish useful criteria the surgeon to judge the evolution of the operated tendon.

The first step consists in evaluating the feasibility of the acquisition of dynamic sequences in MRI and the possibility of observing the movement of the flexor tendon operated during the mobilization of the finger, and comparing the biomechanical data obtained with those of the nonoperated tendons and experimental models.
