gradual
31

- Groin and possibly anteromedial thigh P! and to the knee - Intermittent but worsening with gradually and unknown - Even occurring at rest due to ischemia
33
What will we observe with osteonecrosis?
antalgic and asymmetrical gait
34
What will we find with ROM of those with osteonecrosis?
ROM- limited IR, abduction, and flexion due to greater bony contact
35
What other condition S&S will be present with osteonecrosis?
Age-related Joint Change S&S
36
What is the referral of osteonecrosis if gradual onset??
Urgent referral to MD if gradual onset
37
If patient with osteonecrosis is referred to PT how do we proceed?
if referred for PT proceed with caution
38
What kind of PT measures can we do with those with osteonecrosis?
- Gait training with an assistive device is often necessary to protect the femur - PT directed primarily at protection motion, improving circulation, and for bone and cartilage integrity; like age-related joint change Rx
39
What may happen with those with osteonecrosis?
May end up having a Hemi-arthroplasty or possibly a THA
40
What is Legg-Calve-Perthes?
- aka as coxa plana or flat hip - AVN of the femoral head in children
41
What is the etiology of Legg-Calve-Perthes?
- Trauma - Exposure to 2nd hand smoke - Prenatal factors, i.e., genetics, endocrine, nutritional, or socioeconomic conditions - Developmental dysfunction of bone or vasculature
42
What population is Legg-Calve-Perthes MOST common in?
MOST common in 5-8 yr. old Caucasian biological boys
43
What is the pathogenesis of Legg-Calve-Perthes?
impaired vascular supply to epiphyses (med/lat circumflex aa) that changes shape of the femoral head and acetabulum
44
What are PT clinical manifestations of Legg-Calve-Pethes?
- Vary in magnitude - Gradual and unknown onset primarily - If P!ful, groin and possibly anteromedial thigh P! and to the knee - Increased with activity - Decreased with rest
45
Is Legg-Calve-Perthes gradual or sudden onset?
gradual and unknown
46
What will we observe with Legg-Calve-Perthes?
- Antalgic and asymmetrical gait - Muscle atrophy if long standing
47
What will we find in ROM with Legg-Calve-Perthes?
limited IR and aBd due to greater bony contact
48
What is the referral with Legg-Calve-Perthes?
A long-term problem - Urgent referral to MD if gradual - Emergency referral to MD if trauma - If referred for PT proceed with caution
49
How can we treat Legg-Calve-Perthes with PT?
- PT directed primarily at protected motion, improving circulation, and for bone and cartilage integrity - Periodically, splinted, braced, or casted in slight abducted position - Better femoral head contact with acetabulum - Maintain and help better form femoral head in acetabulum as healing can occur
50
Why can we do gait training with Legg-Calve-Perthes?
Gait training with an assistive device is often necessary to protect the femoral neck
51
What is a complication with Legg-Calve-Perthes?
Complication: prone to contractures
52
What should we know about Legg-Calve-Pethes and Age related Joint changes?
Possible age-related joint change in early adulthood and 50% will develop age related joint disease before 50 yrs. of age
53
What will MOST with Legg-Calve-Perthes need? What can happen earlier due to gait dysfunction?
MOST will need corrective surgery and/or early total hip arthroplasty - Earlier LB and knee P! development in life due to gait dysfunction - Kids tend to keep moving - Adults tend to reduce activity
54
What is slipped capital epiphysis?
Anterior displacement of femoral neck on femoral head - aka adolescent coxa vara - MOST significant epiphyseal plate disorder of the LE
55
What is the etiology of slipped capital epiphysis?
- Mostly idiopathic - Association with endocrine and renal disorders and Down Syndrome - Hypothyroidism is MOST common
56
What do the risk factors for slipped capital epiphysis?
- create increased shear forces across epiphyseal plate - Single MOST significant risk factor is obesity - Biological male, rapid growth, radiation therapy, and femoral torsion
57
What is the incidence/prevalence of slipped capital epiphysis?
create increased shear forces across epiphyseal plate - Single MOST significant risk factor is obesity - Biological male, rapid growth, radiation therapy, and femoral torsion
58
What is the pathogenesis of slipped capital epiphysis?
- progressive displacement of femoral neck relative to the head through the growth plate due to shear forces and/or weakened epiphyseal plate
59
How does slipped capital epiphysis come on?
- more likely gradual and unknown onset than trauma, but may seem benign like rolling in bed
60
What is the main complaint with slipped capital epiphysis?
groin and possibly anterolateral thigh pain and to the knee
61
What will we observe with slipped capital epiphysis?
- antalgic and asymmetrical - externally rotated hip - muscle atrophy if long standing
62
What will we find in ROM with slipped capital epiphysis?
- limited IR, abduction and flexion - obligatory ER during flexion
63
What else can come along with slipped capital epiphysis? (other condition)
Possible sign of the buttock
64
When should a slipped capital epiphysis always be considered?
in peri-adolescent with atraumatic hip pain, particularly if associated with antalgic gait
65
What kind of referral is slipped capital epiphysis?
urgent referral to MD
66
What should we do if a patient with slipped capital epiphysis is referred to pt?
proceed with caution
67
How big can the slip be with a slipped capital epiphysis to still be referred to PT?
< 1 cm
68
What will the patient be doing when non WB when referred to PT with slipped capital epiphysis?
splinted in an abducted position with non-WB
69
What can we do with a patient referred to PT with slipped capital epiphysis do post -splinting?
- gait training with an AD is often necessary to protect the femoral neck - PT directed primarily at protected motion, improving circulation and for bone and cartilage integrity
70
When is surgery required with a slipped capital epiphysis?
if slip > 1 cm
71
Why do we need surgery with a larger slipped capital epiphysis?
to avoid AVN or chrondrolysis (rapid loss of articular cartilage)
72
What are S&S of vascular insufficiency?
- coldness - pale, blueish discoloration - diminished pulses - impaired capillary refill with nail bed recovery - shiny skin - hair loss
73
What are PT implications of a vascular insufficiency? How is it different with different types of onset?
- urgent referral with gradual onset - emergency referral with acute onset
