- Tx: Ice, US, Rest, Reposition toes w/ braces/tape
38
Hallux Valgus
Deformity of the 1st metatarsal jt caused by vlagus (lat) mov't of the big toe
-normally causes bunions to from
39
Turf Toe
1st MP jt. sprain
- hyperextension of the great toe
- Causes: Turf (hard), improperly fitting shoes, shoes too flexible (not enough support)
- Tx: Ice, tape toe in neutral position, better shoes to prevent hyper extension.
40
Arch Conditions
painful arches usually result from:
- improper fitting shoes
- overweight
- excessive activities on hard surfaces
- overuse
- faulty posture
- fatigue
41
Ant. Meta Tarsal arch condition
when supporting lig/muscles lose their ability to retain the metatarsal heads in a dome- like shape, placing pressure on nerves/vessels and added stress on meta tarsals
-Tx. Ice, rest, whirl pool exercises, metatarsal pads, reposition arch and set muscles at ease, orthotics, properly fitted shoes.
42
Inner longitudinal arch condition
when supporting muscles/ ligs lose their ability to retain the meta tarsal heads in a dome like shapeplacing pressure on nerves/vessels and added stress on meta tarsals
- Tx. Ice, rest, whirl pool exercises, metatarsal pads, reposition arch and set muscles at ease, orthotics, properly fitted shoes
* longitudinal arch tape support and strengthen foot flexors*

- sprain delt lig
- avulsion of med. malleolus b/c lig may be stronger than bone
47

51
Ankle Side to Side mov't of Talus (Lig stability test)
tests for weakening of the mortise
- move calcaneus and talus from side to side a 1
- if mortise is widened, the talus will be able to move sideways making a thud as it hits the fib
52
Ankle Ant. Drawer test
- Good test
- Ankle in slight planter flex
- Pull calcaneus forward out of "chest"
- excessive fwd mov't indicates ATF damage
53
Talac Tilt/ Inversion Test
attempt to tilt talus into inversion
- pure inversion: tests CF
- Plantar flex and invert: tests ATF
54

- more painful than mild when in stress
- Abnormal ROM
- 2 to 4 week recovery
56
Severe Grade 3 Ankle Sprain
- Complete loss of fcn
- spasms restricts ROM
- cannot bear weight
- abnormal motion in at least one ROM

72
O'Donaghue's Triad
1. MCL

74
Mechanisms of injury to the ACL
1. IR of lower leg, ER of femur and upper body
2. Er of lower leg and IR of femur
3. Deceleration
4. Hyperextension

75
Mechanisms of injury to the PCL
1. Forced is appplied to ant. tibia while knee is flexed at 90, tibia is forced back.
76
Knee Dislocation
- patella dislocates laterally
- true knee dislocation is b/t femur and tibia
- arteries and nerves at risk for being impinged/compressed, potential amputation risk
77
Meniscal Injuries (tears)
- if meniscus is repaired by being sown back up, must wait to bear weight
- if torn meniscus is just cut out, can weight bear as soon as comfortable
78
Chondromalacia Patella
softening of articular cartilage on the post aspect of the patella
79
Patella Femoral Pain Syndrome
-patella does not stay in groove, has tendency to ride over lat condyle of the femur due to contracting quad muscles.
80
IT Band Friction Syndrome
- during flexion and ext. IT band maybe irritated by the lat. femoral condyle and cause:
1. extreme pain
2. loss of stabilization
- irritated by snapping over the lat condyle
81
Osgood Schlatter's disease
- disorder to tibial tubr.
- pain/swelling/pt. tenderness
- caused by kneeling/jumping/ running/ direct trauma
- TX: decrese activity/ice/rest/grad return
