Chapter 134 - Pediatric Foot Conditions Flashcards
four deformities of clubfoot
cavus
adductus
varus
equinus
hindfoot deformity in clubfoot results from?
adduction and inversion of the calcaneus under the talus
forefoot deformity in club foot resutls from what?
medial and plantar subluxation of the navicular as it relates to the talar head
initial clubfoot cast does what?
supinates the forefoot (makes the kid look worse) to correct the cavus
where is the navicular dislocated in congenital dislocation of the talus?
dorsolateral
additional deformities in congenital dislocation of the talus?
eversion of the calcaneus
contracture of the dorsolateral muscles and achilles
attenuation of the spring ligament
clinical exam of congenital dislocation of the talus?
rocker bottom feet
treatment for congenital vertical talus?
reverse ponsetti casting
- foot is stretched into plantar flexion and inversion
- correction gets pinned at the end to hold it with a TAL
how to differentiate congenital vertical talus and congenital oblique talus?
on the forced plantar flexion lateral view
- congenital vertical talus will not reduce
- congenital oblique talus will reduce
calcaneovalgus foot
more common in first born females
no bony issue - all soft tissue/packaging
- must be passively correctable for this diagnosis
- resolves without intervention
metatarsus adductus
packaging disorder
kidney bean shaped foot
neutral hindfoot
must be distinguished against metatarsus primus varus which has isolated varus of the first ray (rigid)
most common tarsal coalition
calcaneonavicular
present younger - 8-12 yo
second most common tarsal coalition
talonavicular
older age at presentation 12-15
middle facet most common
multiple coalitions are foun commonly in
fibular deficiency or apert syndrome
