ankle pathologies Flashcards
1
Q
what is a primary consequency of hallux valgus?
A
hypermobility of the 1st MT
2
Q
what is the main cause of hallux valgus?
A
hyperpronation during propulsive phases of gait
shoes too narrow which compress the feet
3
Q
what can hallux valgus be identified clinically?

1st MT is adducted on medial cuneiform relative to midline
1st phalynx is abducted on MT relative to midline
4
Q
how can hallux valgus be treated

correct for the hyperpronation w/ strenghtening of the intrinsic muscles and posture or orthosis
taping for temporary pain relief
5
Q
what is plantar fasciopathy?

histological degeneration and deterioration of collagen fibers, increased secretion of ground substance proteins and fibroblast in areas of proliferation
6
Q
what clientele is affected by plantar fasciopathy?
A
- very active people
- people w/ a shigh standing workload
7
Q
what causes plantar fasciopathy?
A
degenerative causes due to excessive and repeated loading
low arches: increase the stress in order to stabilize the arch
high arches: inability to pronate foot and thus decreased shock absorption and thus increase stress on foot
-poor MTP extension = poor windlass mechanism = increased stress on plantar fascia
-tightness of myofascial structure = increased pronation or increased tension on fascia
8
Q
what is the most common MOI(s) for plantar fasciopathy?
A
overuse injury (insidious)
WB activivity s/a running
activities w/ excessive mvmt, foot pronation or stressing/stretching of plantar fascia (MTP in full extension, foot hyperpronated or foot hypersupinated)
9
Q
what is the pain site for plantar fasciopathy?

pain worse in am or post activity in WB
if more severe: pain w/ NWB

11
Q
hwta can be noticed in gait in a foot w/ plantar fasciopathy?

hypersupination or hyperpronation
12
Q
what is the effect of having a foot hypersupinated
