COMPENSATIONS Flashcards
the compensations affect what parts of the foot for pes cavus?
equines rearfoot 1st ray LMTJ OMTJ Ankle Limb
what is this compensation?
the forefoot is plantar flexed on the rearfoot, called pseudo equines
creates a high medial arch
forefoot equines
what is this compensation?
plantarflexion of the forefoot can also be at the level of the midfoot
more commonly seen in neurologically caused cavus deformity
midfoot equines
what is this compensation?
in cavus foot you have an increased calcaneal inclination angle
talipes calcaneus affecting the rearfoot
what is this compensation?
plantar flexed in cavus foot
so at contact, the 1st ray wants to dorsiflex but with rigid condition, it can’t dorsiflex much or at all and causes the entire foot to invert behind the 1st ray, supinating the STJ
1st ray
what is this compensation?
in cavus foot, the forefoot is everted at the LMTJ on the rearfoot and so during contact, the forefoot wants to invert at the LMTJ or supinate
but the deformity is rigid and so the forefoot cannot supinate at the LMTJ and so this results in STJ supination
LMTJ
what is this compensation?
in cavus foot, the forefoot is plantar flexed and therefore adducted on the rearfoot at the OMTJ and during contact and midstance, the forefoot wants to pronate at the OMTJ
rigid cavus foot, pronation at OMTJ not possible helping the STJ remain supinated
OMTJ
what is this compensation?
in cavus foot, we see an increased calcaneal inclination angle and a decreased talar declination angle
ankle
what is this compensation?
in cavus foot, there is rearfoot varus and also decreased frontal plane motion at the STJ
limb
