REARFOOT VARUS TERMS Flashcards
normal structural shape of the calcaneus in early uterine development and so the child should outgrow this torsion by the time they walk or shortly after
retain in this position places calcaneus in Paris relative to the ground
ankle joint and STJ unaffected
general varus torsion of calcaneus
a structural variation which is suspected clinically but has yet to be confirmed through research
talus is thicker
this tilts the talus and calcaneus into varus when placed in neutral
theoretical STJ deformity
unequal growth of the distal tibial epiphysis
lateral side is thicker than the medial side
growth abnormality as opposed to a developmental or congenital deformity
tibial epiphyseal varus
NCSP is neutral STJ + frontal plane leg deviation (FPLD with patient in angle and base of gait
occurs in four main areas
- curvature of the whole tibia
- genu varum
- curvature of the distal 1/3 of tibial shaft
- blounts disease (lateral slippage of the proximal tibial epiphysis )
tibial varum
result of all of the potential causes of the rearfoot varus being an inverted rearfoot
in order to compensate for this varus, rearfoot must evert
rearfoot attempts to even GRFs across the plantar calcaneus
compensatory eversion
what is this compensation?
evert the rear foot with STJ pronation until vertical bisection of the calcaneus is perpendicular to the ground
normal compensation
what is this compensation?
patient is able to evert rearfoot from varus position in NCSP to vertical or beyond in RCSP
most common
fully compensated rearfoot varus (most common)
what is this compensation?
patient is able to every their rearfoot form a varus position in NCSP to a less varus position in RCSP?
partially compensated rearfoot varus
what is this compensation?
patient can’t evert at all from varus NCSP
least common
uncompensated rearfoot varus
