Summary

The most important pivot of the sagittal plane is in the first metatarsophalangeal joint, which is usually restricted or blocked as a result of alterations in the rest of the planes or as the main cause of secondary compensations.

Detailed description

In the propulsion phase, once the hallux touches the ground, it does not move again until the moment of take-off, so when there is a limitation of the plantar flexion of the hallux, the compensation of this is appreciated in other anatomical locations during gait analysis. For the propulsion phase to be effective, the first metatarsophalangeal joint must be maximally dorsiflexed. If any structure or movement is altered, the axis varies. In the hallux, the joint surface on which the movement is performed is reduced and therefore affected at the dorsal level, causing a limitation of the main movement of this joint; dorsiflexion in closed kinetic chain, known as functional hallux limitus. It is for this reason that it is proposed to study the application of plantar supports to favor the movement of dorsiflexion of the first metatarsophalangeal joint and avoid an early establishment of the hallux limitus.

Conditions

• Hallux Limitus

Interventions

Type	Name	Description
OTHER	Orthopaedic treatment	Female and male patients aged between 6 and 12 years are included in the study. Initially, the values of dorsiflexion of the tibio-fibular-talar joint and dorsiflexion of the first metatarsophalangeal joint will be measured to rule out hallux rigidus and ankle equinus, respectively. Those patients who do not present hallux rigidus or equinus ankle, will be included in the study and will have their computerized foot pressures taken.
