Flat Feet

Brief summary

Morphological weight bearing computed tomography parameters and gait analysis can implement the evaluation of the flat foot. Weight bearing CT is useful to verify the severity of the 3D deformities typical of flat foot, while kinematic and kinetic variables of gait is able to quantify the functional improvements of the foot after surgery.

Interventions

PROCEDUREmorphological and functional evaluation of adult flat foot

Evaluations are realized by weight bearing computed tomography and by Gait analysis in the pre-operative phase and at a 6-months follow-up from the surgery with Grice technique
