exertional compartment syndrome is often confused with MTSS...how is MTSS different?
MTSS has tenderness to posterior medial tibia, not common in compartment syndrome
no pain with vibratory testing so what condition has a positive sign of this?
management of overuse injuries (acute)
anti-inflam (ice, iontophoresis)
RIE do not use compression
control of biomechanic faults
management of overuse injuries (once symptoms have evolved)
stretching of involved musculature
sub-max, multi-angle isometrics, progressed to isotonic
gradual return to activity
describe subtalar neutral
not pronated or supinated
point of positon that the head of the talus cannot be palpated or is felt to extend equally at the medial and lateral borders of the talonavicular joint
closed chain PRONATION of the subtalar joint
talus rotates down and in
IR of tibia
closed chain SUPINATION of the subtalar joint
talus rotates up and out
ER of tibia
7 criteria for normal foot function during latter part of the mid stance gait
- 1-metatarsals lie in the transverse plane
- 2-plantar surface of the calcaneus is in the transvere plain
- 3-subtalar joint is neutral
- 4-midtarsal joint is locked in its maximum position of pronation
- 5-subtalar joint, ankle joint and knee joint lie in transverse plane
- 6-significant rotational or torsional influences are present
- 7-distal 1/3 of the leg is in sagittal plane
during rearfoot varus what happens?
during forefoot varus what happens?
big toe in air, talus, navicular twisted, pronate late and over pronate
during rearfoot varus and forefoot varus what happens?
flat feet, look like they walk on medial malleolus
during forefoot valgus (rigid)/ rigid plantarflexed 1st ray what happens?
big toe down, really high arch, forces into supination
arch was NOT meant to be a weightbearing structure
generally post 40-60% of the deformity
rigid to semi-rigid
4-6d varus deformity norm
