Braddom - Lower Limb Orthotics Flashcards
device attached or applied to the external surface of the body to improve function, restrict or enforce motion, or support a body segment
Orthosis
Lower limb orthoses are indicated to
assist gait, reduce pain, decrease weight-bearing, control movement, and minimize progression of a deformity.

should be pliable so as not to interfere with the normal biomechanics of the foot.
Pliable
durable, allow ventilation, and mold to the feet with time.
Leather shoes
Tongue part is part of the vamp in
Blucher shoe
The quarters overlap the vamp.
Blucher
recommended for patients requiring an orthosis because there is more room to don and doff the shoe and the orthosis because of the open throat
Blucher
quarters meet at the throat.

Foot orthoses
affect the ground reactive forces acting on the joints of the lower limb.
Foot orthoses
most commonly used in over-the-counter orthoses.

Orthotists usually provide this type of foot orthoses
Semirigid

Still shock absorbing
Rigid
indicated only for a problem that requires aggressive bracing to control a deformity.
Rigid orthosis
To make a custom foot orthosis, the_____ should be placed in a neutral position before casting.
subtalar joint
ankle rotation, such as hyperpronation, and it is also the position in which the foot functions best
Neutral position subtalar joint
used to treat conditions associated with hyperpronation including pes planus, patellofemoral pain.
Subtalar neutral position
also used for difficult orthotic cases where the fiberglass casting itself can be used as a temporary orthosis to determine whether the mold properly controls the deformity.
Fiberglass casting
Pes planus
Flat foot
Pes planus
Symptomatic relief of pain is obtained by
controlling excess pronation of the foot.
can be defined as a rotation of the foot in the longitudinal axis resulting in a lowering of the medial aspect of the foot.
Pronation of the foot
involves pronation at the subtalar joint, dorsiflexion at the ankle joint, and abduction of the forefoot at the tarsometatarsal joints.
Eversion
The key to controlling excess pronation (of flat foot) is controlling the
calcaneus to keep the subtalar joint in a neutral position.
Pes planus can be due to abnormalities such as
excessive internal torsion of the tibia (which results in pronation of the foot) or
malalignment of the calcaneus.
It is the i action between the tibia and the foot at the subtalar joint that allows pathology outside the foot to cause inrolling of the foot
Pes planus
prevents rotational deformities associated with excessive pronation or supination from occurring
Subtalar neutral postion
Elevation of the anteromedial calcaneus exerts an upward thrust against the sustentaculum tali to help prevent
inrolling.
The orthosis should extend beyond the _____ to provide better leverage for control of the deformity.
metatarsal heads
due to abnormalities such as excessive internal torsion of the tibia (which results in pronation of the foot) or malalignment of the calcaneus.
Pes planus
custom-made foot o sis designed to prevent hyperpronation is also referred to as
UCBL orthosis (or UCB)
two common mistakes noted in custom foot orthoses.
Some Not made by orthotists
some custom foot orthoses do not cup the calcaneus but rather merely serve as a platform to stand on.
Some cases of pes planus are due to ligamentous laxity within the foot.
Mgt
medial longitudinal arch support
term for increased medial length to heel) can also offer medial support, particularly for heavier individuals.
Thomas heel extension
Runners with pes planus
Mgt
purchase a pair of running shoes with a firm medial heel counter as well as shoes with a wide last at the shank
High arched foot
Pes cavus
typical complication of pes cavus
excess pressure along the heel and metatarsal head areas, which can lead to pain
Pain pes cavus prevented by
making the height of the longitudinal support just high enough to fill in the space between the shank of the shoe and the arch of the foot to distribute weight more effectively.
Weight should also be evenly distributed over the metatarsal heads.
Pes cavus
High point
Talonavicular joint
Pes cavus
If the tibia is externally rotated (see Figure 15-2), this can give the appearance of an elevated arch as the foot supinates and the lateral aspect of the foot assumes additional weight-bearing responsibility. In these cases a foot orthosis is custom molded with the subtalar joint in a neutral position to prevent excess supination from occurring.
In these cases a foot orthosis is custom molded with the subtalar joint in a neutral position to prevent excess supination from occurring.
Metatarsalgia
Forefoot Pain
Relief of pain in the forefoot is accomplished by
distributing the weight-bearing forces to an area proximal to the metatarsal heads
Forefoot pain
Placed
inside the shoe just proximal to the second, third, and fourth metatarsal heads. It should also be just proximal to the lateral aspect of the first metatarsal head and medial to the fifth metatarsal head
recommended for cases in which the foot is too sensitive to tolerate a pad inside the shoe.
metatarsal bar
typically 1 ⁄4-inch thick and tapers d tally.
Metatarsal bar
The metatarsal bar is typically 1 ⁄4-inch thick and tapers distally. The distal edge should be proximal to
the metatarsal heads.
can also be used for forefoot pain a ciated with pes cavus.
metatarsal bar
can also be used for metatarsalgia to decrease the force on the metatarsal pad region at push off.

Prevention of forefoot pain should also be emphasized to patients. Patients should avoid shoes with
high heels or pointed toes, which place excess stress on the metatarsal heads.
Heel Pain
The painful area can be alleviated by using
an orthosis to help distribute weight

Heel pain
Rubber heel pads
recommended for cases in which the foot is too sensitive to tolerate a pad inside the shoe and the heel pain is associated with a chronic condition
calcaneal bar
Spring - heel set on anterior calcaneus
The calcaneal bar is placed
distal to the painful area to prevent the calcaneus from assuming full weight-bearing status.
application of a _____ can also be used to help initiate heel strike anterior and the ground reaction force anterior to the painful calcaneus

A common cause of heel pain along the anteromedial calcaneus
plantar fasciitis.
common cause of heel pain along the anteromedial calcaneus is plantar fasciitis. Pain occurs at the
attachment site of the fascia along the medial aspect of the heel.
