Q 
Tx of congenital hip dislocation
First 6 weeks
6 months - 6 years
7-10
After 11
A

For the first 6 weeks of life - positioning the hip in abduction, ER, and flexion through a double diaper or Pavlik Harness
From 6 months - 6 years - closed or open reduction is necessary and LE is immobilized
7-10 = if bilateral patient may be functionally OK or else surgical tx occurs
After 11 not surgical tx occurs unless they have degenerative changes

Q

Impact of legg calve perthes

A

Avasular necrosis of the femoral head occurs secondary to a subchondral fracture or occluded blood supply
Eventually the necrotic ossification tissue is replaced by normal disuse but the shape of the femoral head is not correct

Q

Tx for avascular necrosis

A

Conservative tx is NWB for 2-3 yrs in young patients
Most patients opt for surgical internal fixation of femoral head and grafts to revascularize the bone
Total hip arthroplasty is an option too

25
All patients with avascular necrosis develop - | Tests to diagnose
OA Radiographs
26
Septic Hip/Arthritis
Medical emergency and needs immediate treatment | Can occur at any age but usually occurs in adults
27
If not treated for septic hip...
hip joint will be destroyed - pathogens include | Gonorrhea, H influenza, Staphylococcus, Steptococcus
28
Septic hip is divided into
gonococcal arthritis and non-gonococcal arthritis | Most common non- gonoccoal pathogens are H influenza, Stph and Strep
29
Degenerative Joint Disease
Breakdown of cartilage on the femur or acetabulum Can be idiopathic or in response to injury or disease Females > Males Over age of 40
30
Subjective Complaints with DJD
Groin or trochanteric pain | Morning stiffness less than 30 min
31
Objective findings with DJD
``` Antalgic gait Loss of hip motion Weak abductors Crepitus Muscle spasm ```
32
Dx is confirmed with (DJD)
radiographs
33
Treatment for DJD
Conservative tx is symptom relief and stress control via medications, joint mobilization and stretching, assistive and adaptive equipment, and hip strneghtening
34
Surgical tx for DJD
Birminghman procedure for younger patients and total hip arthroplasty
35
Prognosis for DJD
Pain will increase as degeneration continues
36
Hip Pointers or Iliac Crest Contusion
Contusion of the iliac crest, ASIS, or both Caused by trauma and can cause soft tissue damage to surrounding mm (RF, Sart, TFL, E/IO) Avulsion needs to be ruled out
37
Tx for Hip pointer or iliac crest contusion | Prognosis
initial rest with gradual return to function | Prognosis is full recovery
38
Hip fractures
1. Avulsion 2. Subcapital 3. Femoral neck 4. Intertrochanteric 5. Subtrochanteric 6. Stress
39
Stress fracture
Insidious and often happen in individuals with osteoporosis, runners, elderly, patients with cancer, individuals with compromised nutrition
40
When do stress fractures occur
When osteoclastic activity outweights osteoblastic activity
41
Patient will complain of (stress fracture)
pain with weightbearing
42
Tx for stress fracture
rest but if fracture is through a major weight bearing area, ORIF might be necessary
43
Prognosis for stress fracture
good for return to activity but not if nutrition and training do not change
44
Subtrochanteric Fracture
Occur with major trauma primarily in elderly from falls and from other traumas in young people Fractures are classified by degree of displacement and number of fragments of bone
45
Subejctive info Subtrochanteric Fracture
pt will show an acute onset of pain, inability to weightbear and a shortened and externally rotated LE
46
Tx for subtrochanteric fracture
ORIF
47
Prognosis for subtrochanteric fracture
poor for elderly to get to full function | mortality up to 80% within 2 years of the fracture
48
Intertrochanteric Fracture
Caused by falls and trauma | Classified by degree of displacement and location
49
Tx of Intertrochanteric fracture
ORIF
50
Prognosis of intertrochanteric fracture
Poor prognosis for return to function in elderly
51
Femoral neck (subcapital) fracture
More likley to have a sequelae of avascular necrosis secondary to the femoral circumflex artery
52
Classification of fractures (femoral neck)
Grade 1 = Incomplete Grade 2 = Nondisplaced Grade 3 = Partial Displacement Grade 4 = Total displacement
53
Tx for femoral neck fracture
Most hip fractures are treated with ORIF but type of fixation depends on kind of fracture and its classification Weightbearing status also depends on type of fracture, classification, and bone integrity
54
Avulsion Fracture
Caused by a strong muscle contraction resulting in pulling the muscle attachment and small amount of bone off a larger bone Most common in athletes who still have open epiphyseal plates Pain is localized to the muscle attachment and action with swelling, redness, and bruising
55
Diagnosis avulsion fracture
Radiographs are diagnositc choice to differentially diagnose an avulsion fracture versus muscle or tendon strain
56
Tx goals for avulsion fracture
Focus on proper healing with initial rest and gradual return to activity
57
Prognosis for avulsion fracture
Excellent for return to function and better than someone who had sustained a tendon tear or muscle tear
58
Hip dislocations - Anterior or Posterior
Can be ant or post depending on force direction Considered a medical emergency secondary to structures that may be damaged by the force needed to dislocate Not very common because of stability of hip but can occur with large trauma like MVA
59
Hip dislocations almost always damage
the labrum | Complications can occur like avascular necrosis or nerve damage
60
Posterior hip dislocation can impact the | Anterior can impact the
sciatic nerve Femoral nerve
61
Tx for hip dislocation
Closed reduction under anesthesia if no fracture has occured and ORIF if fractures occur
62
Prognosis for hip dislocation
Full recovery is good if avascular necrosis does not occur
63
Femoral Acetabular Impingement
Syndrome of painful hip motion (usually flexion, adduction) that results from underlying bony abnormalities in the hip joint Labral tears, DJD my be a result
64
2 deformities with femoral acetabular impingmeent
Cam Impingement = femoral head/neck protrusion Pincer Impingement = acetabular coverage on the femoral head When hip is flexed and adducted like when cross legs, acetabulum may pinch the bone and joint capsule and labrum causing pain FAI can also be caused by muscle imbalances and capsular tightness
65
FAI is leading cause of
labral tears
66
Labral Tears
Usually caused by microtrauma or FAI, capsular laxity or hip dysplasia Occur in highly active people ages 20-40
67
Subjective complaints
Generalized ant groin pain or clicking, locking or giving way
68
Diagnosis labral tear
No clincial exams with high validity | Radiographs, MRI, bone scan, intraarticular injectiosn might be used to rule out other problems
69
Tx for labral tear
Intraarticular injections to dec inflammation, PT for hip mobiliztaion, muscle balancing, lifestyle changes, and arthroscopic repair
70
If untreated, labral tears are thoguht to lead to
DJD
71
Hip bursitis
Inflammation of the bursa usually the greather troch, iliopectineal, or ischiogluteal F > M
72
GT bursitis occurs most frequently in
30-40 y/o and is most common cause of hip pain
73
Subjective findings with hip bursitis
Tenderness is usually achy and diffuse in GT area with radiation to groin, glutes or thigh Pain occurs with resisted abduction With IP, IG, pain is at the site and area of bursa
74
Objective findings with hip bursitis
Gait is antalgic
75
Tx for hip bursitis
Rest, stress reduction, normalizing movement or postures, stretching and strnegthing are PT txs Medical tx = injections and NSAIDS (non steroidal anti inflammatory drugs)
76
Greater Trochanteric Bursitis
Fairly common | May be caused by trauma, weak abductors, forceful adduction
77
ischial gluteal bursitis
Can be caused by over use of hamstrings, onto ischial tub, prolonged sitting
78
Iliopectineal bursitsi
can be caused by tight iliopsoas rubbing against bursa, an abnormal hip joint from RA or OA that causes irritation to bursa
79
Hip tendinopathy
Usually occurs in the tendons of greater troch or proximal hamstring Cause = usually overuse Pelvic obliquities and leg length discrepency can irritate GT tendons
80
Diagnosis of tendinopathy
Via palpaton and resisted contraction with occasional MRI
81
TX of tendinopathy
Depends on if it is tendonitits but usually always includes eccentric exercise
82
Muscle Strain
Tearing of a muscle Usually ecchymosis occurs Palpation to muscle would be painful
83
Common hip muscles to strain
Adductors, RF, Hamstrings | Two joint muscles are strained more commonly
84
Mechanism of muscle strain
Mechanism is usually forceful contraction as the muscle is lengthening or trauma
85
Inflammatory problem - best tx
Ice, STM, Painfree AROM, gait training
