Q

What are the different types of Osteogenesis Imperfecta?

A

Type I: mildest form, frequency of fractures decreases after puberty
Type II: most SEVERE, child dies in utero or early childhood
Type III: severe, greater ossification of the skull, growth retardation, ongoing fractures, significant funcitonal limitations
Type IV: mild to moderate fragility (greater than type I), will have bowing of long bones

Q

What is most commonly seen with motion of the patella in patellofemoral syndrome?

A

The patella is pulled too far laterally, so medial patellar glides may be useful

Q

What foot posture can exacerbate patellofemoral syndrome?

A

Pronated feet

20
Q

Piriforomis syndrome causes compression or iritation of what?

A

the sciatic nerve

21
Q

What exacerbates symptoms of piriformis syndrome?

A

prolonged sitting and activities combing internal rotation and adduction

22
Q

What position will reproduce pain in piriformis syndrome?

A

Flexion, adduction, and internal rotation

23
Q

Piriformis syndrome has a near identical presentation to what?

A

L5-S1 radiculopathy

24
Q

Where is pain located with plantar fasciitis?

A

the origin at the medial tubercle of the calcaneous

25
What are some factors that can lead to the development of plantar fasciitis?
Excessive pronation with gait, tightness of foot and calf musculature, obesity, and a hihg arch
26
Why is the most severe plantar fascia pain in the morning?
the fascia is contracted, stiff, and cold
27
What bony hypertrophy may occur with plantar fasciitis?
Heel spur
28
What stretching should a patient with plantar fasciitis do in the morning?
a plantar fascia and gastrocnemius stretch
29
What orthotic is often prescribed with plantar fasciitis?
a heel cup
30
How long does it take for patients to get to a more functional level with plantar fasciitis? How long does it take for complete resolution of symptoms?
1. 8 weeks | 2. 1 year
31
What is the path of PCL?
POSTERIOR intercondylar area of the tibia to the lateral aspect of the medial femoral condyle in the intercondylar notch
32
What are the two most common causes of a PCL tear?
1. landing on the tibia with a flexed knee | 2. Hitting a dashboard in a MVA with a flexed knee
33
What strengthening exercises should be avoided to allow a PCL to heel?
Exercises that place a posterior shear force on the knee --> open chain hamstring exercises Posterior shear, like sliding the TIBIA POSTERIOR (lag sign). Hamstrings are attached posteriorly so it'll pull posterior since hamstrings aren't counteracting.
34
What disease is a chronic inflammatory reaction in the synovial tissues of a joint that results in erosion of cartilage and supporting structures within the capsule?
Rehumatoid Arthritis
35
What are swan neck and boutonniere demority?
Swan neck: DIP flexion, PIP hyperextension --> need to hyperextend to make a long neck Boutonniere: DIP extension, PIP flexion
36
80% of individuals with RA show what blood factor?
Rheumatoid Factor (RF)
37
What is one example of a DMARD that may be used to treat RA?
methotrexate
38
During the acute stage or exacerbation of RA what should be avoided in PT?
resisitive exercise, deep heating, and any form of active stretching
39
During the chronic stage or remission stage of RA what should be avoided in PT?
aggressive stretching
40
What systemic symptom is common with RA?
low grade fever
41
After a rotator cuff tear a patients arm is typically positioned in?
Internal rotation and adduction
42
How long will patients be immobilized after a large rotator cuff repair? how long does it take for patients to return to dynamic overhead motions? How long for functional return?
1. 4-6 weeks 2. 9-12 months 3. 4-6 months
43
What is are the most commonly torn rotator cuff tendons?
Supraspinatus but also infraspinatus and subscapularis with more severe or traumatic etiologies
44
Which type of rotator cuff tear causes the most pain and why?
Partial tearing due to increased tension on remaining muscle fibers and associated neural tissue
45
Failure to adequately treat a rotator cuff can result in what happening to the tendon?
Since the tendon does not heal, it forms scar tissue and there will be an increased risk of rupture or an increase in size of original tear
