Foot Orthosis Flashcards
Types of foot orthoses
- Internal Modification (Inserts and Fixed)
- External Modification
These are used to relieve pain and activity limitation associated with pes cavus.
Insert Orthoses
Type of foot orthosis that reduces load on painful heel.
HEEL-SPUR INSERT ORTHOSIS
It has a concave relief to minimize pressure on the
tender area and helpful for patient who have plantar fasciitis.
Heel-Spur Insert Orthosis
This foot orthosis/support is positioned at the medial longitudinal arch which prevents depression and pronation of subtalar joint. Also, prevent flattening of the arch.
Longitudinal Arch Support
This foot support/orthosis has a minimum support which positioned at the medial border of the insole with the apex between the sustentaculum tali and navicular tuberosity. Also ,support medial longitudinal arch.
Scaphoid Pad
○ corrects flexible flat foot (MLA)
○ controls hindfoot valgus
○ limits subtalar motion (pronation)
○ the insert encompasses the heel and midfoot
UNIVERSITY OF CALIFORNIA BIOMECHANICS LABORATORY (UCBL) INSERT
Type of insert orthoses are used with pes cavus or clubfoot deformity that transfers weight from metatarsal head to the metatarsal shaft.
Metatarsal Pad
A convex component that may be incorporated in an insert or may be
a resilient domed piece glued to the inner sole so that its apex is under the metatarsal
shafts.
Metatarsal Pad
Indications for Metatarsal Pad.
Diabetic Neuropathy- the pad transfers stress from the metatarsal heads to the metatarsal shafts effective in
reducing plantar pressure.
Effective in reducing plantar pressure particularly in patients with diabetic neuropathy.
External Modification
Type of External Modification:
○ alters alignment of the rearfoot
○ medial or lateral heel wedge (depends on the deformity)
Heel Wedge or Heel Post
Type of External Modification:
○ named based on the desired motion
■ e.g., varus or valgus posting
○ rearfoot and forefoot posting
Posting
Medial Heel Wedge Indications:
To correct flexibility:
1. Pronation
2. Eversion
3. Pes Valgus
4. Pes Varus
5. Flat foot
To accommodate rigidity:
1. Supination
2. Inversion
3. Pes Varus
4. Pes Cavus
5. Clubfoot
Lateral Heel Wedge Indications
To correct flexibility:
1. Supination
2. Inversion
3. Pes Varus
4. Pes Cavus
5. Clubfoot
To accommodate rigidity:
1. Pronation
2. Eversion
3. Pes Valgus
4. Pes Varus
5. Flat foot
This type of external modification is indicated for flexible pes valgus which can be attached at the anterior border of medial side and extended forward.
Thomas heel
Type of External modification:
○ placed posterior to metatarsal heads
○ transfers stress from MTP joints to metatarsal shafts during late stance
○ Indications: metatarsalgia
Metatarsal Bar
Type of External Modification:
○ convex transverse band affixed to the sole proximal to the
metatarsal heads
○ reduces the distance the wearer must travel during stance
phase
○ improves late stance
○ shifts load from MTP joints to MTP shafts
○ Indication: patients with difficulty in push-off (rocker)
Rocker Bar or Rocker Bottom
Type of external modification:
○ should be made from non-compressible material
○ raises one foot in order to shift balance
○ Indication: leg length discrepancy that is beyond half an
inch
