Hip Conditions Flashcards
When you have Avascular necrosis what hip ROM is decreased?
Flexion, IR, abd
What are the 3 clinical findings with Avascular necrosis?
- Pain in groin and/or thigh
- Tenderness to palpation at hip joint
- Coxalgic gait
What is the age onset for leg-calve-perthes disease? And is it more in males or females?
2-13 years old
4x more likely in males
What diagnostic tests are used or leg-calve-perthes disease?
MRI, bony crest findings
What are the 4 clinical findings for leg-calve-perthes disease?
- Psoatic limp due to weakness of psoas
- Effected LE moves into ER, flex, add
- Gradual onset of “aching” pain at hip, thigh and kness
- Limited abd and ext
What is the most common hip disorder in adolescents with unknown etiology?
Slipped capital femoral epiphysis
What is the age onset for slipped capital femoral epiphysis?
Males: 10-17
Females: 8-15
Males 2x more likely
What are the clinical findings for slipped capital femoral epiphysis?
- Vague pain at hip, knee, thigh
2. Chronic~trendelenburg gait
What is the degree for excessive femoral anteversion?
25 degrees or greater
What is the angle less than 0 degrees called and why?
Femoral retroversion because the femoral neck is rotated backward inn relation to the femoral condyles
What are the 3 clinical findings for femoral anteversion?
- Squinting patellae
- Toeing in
- Positive Craig’s test
What is the angle for coxa vara?
What is the angle for coxa valga?
> 125 degrees
What can coxa vara often result from?
Defect in ossification of head of femur
What can both coxa vara/valga result from?
Necrosis of femoral head occurring with septic arthritis
What is trochanteric bursitis often comorbid with?
ITB syndrome
What can cause the inflammation of the deep trochanteric bursa?
Trauma, irritation by ITB, bio mechanical stress
What is the etiology of ITB syndrome?
Tight ITB and/or gait abnormality
Where is the pain with ITB syndrome?
Trochanteric bursa and/or lateral epicondyle
What are the clinical findings for ITB syndrome?
- Positive noble compression test
2. Positive ober’s test
What may cause overworked piriformis?
Excessive pronation of the foot, which causes abnormal internal femoral rotation
What may happen with a tightness or spasm of the piriformis muscle?
Compression of the sciatic nerve and/or SI dysfunction
What are the two muscles that may be associated with ITB syndrome?
Glute max and TFL
What are the 5 clinical findings with pririformis syndrome?
- Restriction of IR
- Tenderness to palpation of piriformis
- Referral of pain to posterior thigh
- Weakness in ER
- Positive FAIR test
What is the diagnostic test for piriformis syndrome?
EMG/NCV
What results in an impaired blood supply to the femoral head?
Avascular necrosis
