What is Forefoot Vatral position and varus?
|
a structural abnormality in which the foot is inverted relative to the rearfoot, when the STJ is in its neutral position and the MTJ is locked at both its axes
|
|
|
What is Forefoot Supinatus
|
a fixed supinated position of the LA of the MTJ which is secondary to STJ pronation when the calcaneus is everted. It is a 2 degrees positional deformity resulting from tissue adaptation
|

What is the Aetiology of Forefoot varus?
|
- Theorised to be failure of the normal development of valgus torsion in the head and neck of the talus
- Pf of the cubiod resulting in pf 4th and 5th met - Pf 5th met |
|
|
What is the difference between Forefoot Varus and Forefoot supinatus?
|
In the assessment position (STJ neutrall and MTJ locked), if an inverted forefoot if present and there is a spongey resistance to eversion ofthe LA of the MTJ, Ffoot supinatus is present, often concoitant with a varus
|
|
|
How can forefoot supinatus be reduced?
|
It may be reduced with orthotic therapy, and so should be recognised and or casted out in negative casting.
|
|
|
What are the pathomechanics of Ffoot varus and supinatus?
|
- Ffoot is inverted with forefoot loading
- Increase ground reaction forces lateral to STJ axis - STJ pronation until Ffoot contacts or STJ ROM is used up |
