UCBL Flashcards
The primary joint being controlled in a UCBL foot orthosis is the
Subtalar
A major requirement for successful application of the UCBL foot orthosis is that?
Deformity must be flexible
To achieve additional valgus control with the UCBL foot orthosis
Add a medial flare to the heel and forefoot
The effectiveness of a UCBL foot orthosis in controlling stance phase floor reaction forces is dependent upon the?
Intimacy of foot in shoe and orthosis
The main advantage of the UCBL foot orthosis over conventional shoe modifications is that the?
Corrective forces are applied directly to the foot
In selecting a shoe to be used with a UCBL for orthosis, a major requirement is that the?
Shoe must provide a stable base of support
The UCBL provides
Inversion and eversion stability
The UCBL foot orthosis applies corrective forces to?
Hind foot, mid foot and plantar surface
With proper design the UCBL foot orthosis can
Addict and abduct either the forefoot and or the mid foot
The longitudinal arch of the foot can be depressed by
Abducting the forefoot
An impression for a UCBL foot orthosis is taken with the patient.
In partial weight bearing with corrective forces applied
Footboards used for taking an impression for a UCBL foot orthosis generally come in three heel heights?
3/8, 1/2, and 5/8 inch
The anterior distal trim line for the UCBL for orthosis is drawn
6mm proximal to the metatarso_phalangeal crease
When applying corrective forces as an impression is being taken for a UCBL foot orthosis,the orthotist must
Maintain ankle and forefoot correction
While taking an impression for a UCBL foot orthosis, internally rotating the tibia will
Depress the longitudinal arch
While taking an impression for a UCBL foot orthosis, externally rotating the tibia will
Elevate the longitudinal arch
The plantar surfaces of the forefoot And hind foot should be kept
Parallel
Prior to taking an impression for a UCBL foot orthosis, the following landmarks should be marked
Malleoli, navicular, anterior/medial calcaneal tuberosity, base of 5th MT, and distal trim line
In modifying a cast for a UCBL, the malleoli would more likely be
Built up 3 mm
The area of the Achilles’ tendon on the cast for a UCBL foot orthosis should be
Shaved 1.5 mm laterally
In order to create a tighter grip of the hind foot, the cast for a UCBL foot orthosis should be?
Shaved on the sides of the Achilles’ tendon
The cast for a UCBL foot orthosis should be modified so that the?
The plantar surface at the MT heads is parallel to the plantar surface of the calcaneus
When the navicular is included in a UCBL foot orthosis, that area of the cast should be
Built up 3mm
To increase the amount of medial support of a UCBL foot orthosis plaster should be
Removed in the area of the sustentaculum talk
To achieve the maximum medial support the sustentaculum tali modification should be
Merged with that of the medial heel grasp modification
It is best to evaluate a UCBL foot orthosis on the patient?
Prior to, during, and after ambulation
Corrections to a UCBL foot orthosis must be made if skin redness due to excessive pressure persists for more than?
15 minutes
The proximal trimlines in the area of a UCBL foot orthosis should be
6mm distal to the shoe
Pressure on the metatarsal heads can be relieved by incorporating a pad
Proximal to the MT heads
When the patients foot is positioned At 90 degrees in a UCBL foot orthosis, the gap at the Achilles’ tendon should be
No more than 4mm
Bony prominences within the UCBL foot orthosis should be evaluated
To ensure excessive pressure does not exist
Two biomechanical treatment objectives of a UCBL foot orthosis during weight bearing are
Keep subtalar joint in neutral and Achilles’ tendon straight
During ambulation with a UCBL foot orthosis the heel area should
Not move excessively within the orthosis and cause skin irritation
If areas on a UCBL foot orthosis cause excessive pressure
Reliefs should be formed by localized heating of the plastic
In order to control excessive motion of the subtalar joint, the UCBL foot orthosis should be made from a
Flexible plastic such as polypropylene or laminated polyester
Before being applied to the patient the edges of the UCBL foot orthosis should be
Rounded and smooth
The distal edge of a UCBL foot orthosis should be
Tapered
The advantage of fabricating a UCBL foot orthosis from thermoplastic is that it
Can be easily reshaped
When removing the UCBL foot orthosis for the cast
The plastic should be cut outside the trim lines so that the definitive trim lines can be established subsequently.
If the UCBL foot orthosis is removed too soon from the cast
The heel diameter may increase causing a loose fit.
The primary bone being stabilized in a UCBL foot orthosis is the
Calcaneus
