medsibridge review Flashcards
what percentage of the superior aticilar surface of the talus is covered by cartilage
60%
what is Sever’s disease
- calcaneal apophysitis is an inflammation of the growth plate in the heel of growing children - caused by repetitive stress to the heel and is thus particularly common in active children - occurs during the growth spurt of adolescence ages of 8 and 13 for girls and 10 and 15 for boys.
what is a Jone’s fracture
5th met fracture in the shaft
how many bone are in the phalanges
1st - 2, but the rest have 3
what type of hinge best discribes the rearfoot
How does the rearfoot position change in WB and NWB with a pronated foot postures
NWB eversion, abduction and DF
WB eversion, abductio and PF
Descirbe the shape of the chopart joint
“S” shapred with talonavcular convest on cave
What is the reference point for tarsal motion
the second ray
- adduction is motion towards the 2nd tarsal
- abduction is motion away from 2nd tarsal
how with the forefoot compensate for insufficent midfoot motion with rearfoot supination
Pronation twist
- splaying of the forefoot with PF, AbD of the first ray and DF, AbD of 3-5 rays
What are the axis of motion of the transvere tasal joint and what motions occur there
longitudinal - inversion eversion
oblique - PF/DF and AbD/AdD
What do the FPI scores indicate about the foot posture
neagtive score supinated
0 neutral
postive in pronated
what are the 6 observations you make with the FPI
- talar head position
- medial malleolar curves
- calcaneal frontal plane
- talonavicular prominance
- medial arch
- forefoot horizontal plane
what is the scoring criteria for FPI
- 0-5 normal
- 6-9 pronated
- greater than 10 highly pronated
- supinated -1 to -4
- highly supinated greater than -5
Statistical data of FPI
64% ability to predict variation
.81-.91 intratestor reliability (same person)
.83 intertestor (different people)
Describe the treatment direction model of pathology for orthotic presciption
Identify the direction or mechanism of symptoms and develop the orthotic around the symptoms
- influence motion impairment
- influence force management
- protect soft tissues
- alter muscle activity
- knee pain
- manage foot deformities
Research suggest what test for determing orthoic presciption with plantar fasciitisF
Foot taping trial
What variable could separate fat pad atrohpy from PF
fat pad atrophy is more likely to present (B)
Runner’s with PF are more likely to have what type of foot posture
Negative FPI or supinated
How will weight bearing change between the various grades of ankle sprains
grade 1 able to bear wieght without assistive device
grade 2 able to bear wieght with an assistive device
grade 3 unable to bear weight at all
