Foot Windlass Mechanism was first described by Hicks in 1954

Windlass Mechanics in the PreClinical Clubfoot Deformity[]

PCFD Wt Bearing

PreClinical Clubfoot Deformity Standing

Above midstance photo is taken from a patient having the PreClinical Clubfoot Deformity.  Note, that when weight is applied to this foot structure, the inner longitudinal arch collapses.

PreClinical Clubfoot Deformity, weight on forefoot at heel lift

Above heel lift photo is taken from the same patient.  Note, that when the toes are flexed (e.g., at heel lift), the inner longitudinal arch is reestablished.  This is the direct result of Windlass Mechanics acting on the foot.  

When analyzing treadmill videos of patients having the PreClinical Clubfoot Deformity, one will observe the Windlass Mechanics.
