In Depth Tutorials and Information
Hallux rigidus:
severe limitation of motion at the first MTP joint. The
end result of the osteoarthritis that reduces first MTP joint motion to
produce hallux limitus.
Hallux valgus:
complex deformity of the first MTP joint involving
deviation of the great toe toward the lesser toes. Predominantly a
transverse plane deformity, but the hallux may also rotate in the
frontal plane.
Heel pitch:
viewing the shoe from the side, this is the angle created
by the heel height relative to the front part of the sole. The higher the
heel, the greater the heel pitch.
Hypermobility:
generally, refers to increased flexibility of the joints,
allowing them to bend or move beyond their normal range of motion,
which may be local or generalized; in relation to the foot, can also
refer to functional hypermobility, which describes a lack of functional
stabilization of an anatomical unit. For example, the pronated foot
where the ability of fibularis longus to stabilize the first metatarsal is
compromised. This can result in first MTP joint deformity or
pathology.
Inverted/inversion:
movement in the frontal plane, so the plantar
surface of the foot moves towards the midline of the body and away
from the transverse plane.
Lateral:
denoting a position further from the median plane or midline
of the body or a structure.
Medial:
denoting a position toward the median plane or midline of the
body or a structure.
MTP:
metatarso-phalangeal.
Ontogeny:
the complete developmental history of an individual
organism.
Orthosis (plural: orthoses):
a support, brace or splint used to
support, align, prevent or correct the function of movable parts of the
body. Shoe inserts are orthoses that are intended to correct an
abnormal or irregular walking pattern, by altering the angle at which
the foot strikes, and interacts with, a walking or running surface.
Orthotic:
serving to protect, or to restore or improve function;
pertaining to the use or application of an orthosis (an orthotic device,
an orthotic service).
Osteopenia:
reduction in bone mass, usually caused by a lowered
rate of formation of new bone that is insufficient to keep up with the
rate of bone destruction.
