Current concepts key points Flashcards
what would heel/ toe walking tell you?
Heel walking- gross screen of deep peroneal nerve
toe walking- superficial peroneal nerve
What ligament secures L5 to ilium?
Iliolumbar ligament
How would you differentiate between a groin strain and Obturator nerve entrapment?
Obturator nerve would be aggravated by stretching into abduction and slight extension
groin strain would be painful with resisted adduction
How could you test for femoral nerve entrapment
Modified Thomas test
What is the most common LE nerve entrapment
Common peroneal nerve
Describe the difference between form and force closure
Form- fit between sacrum and innominates (how bones fit together
Force- muscles and ligaments fit together to maintain stability
Describe the difference between nutation and counternutation
Nutation- anterior tilt of sacral base in relation to ilium (posterior iliac tilt) AKA SACRAL FLEXION
Counter nutation- posterior tilt of sacral base relative to ilium (anterior iliac tilt) AKA SACRAL EXTENSION
Describe common MOI for SIJ dysfunction
Extreme loading in one leg
Activities involving torsional movement
What is the Sacroiiliits clinical prediction rule (Laslett’s cluster)
Thigh thrust, compression, distraction, sacral thrust, gaenslen- if 3/5 tests + can rule in
What is the clinical prediction rule for sacroillitis (Vanderworth cluster)
Distraction/ gapping, compression, FABER/ Patricks sign, thigh thrust, Gaenslen- 3/5 + tests
Describe the Fortin Finger test
Pointing with 1 finger close to the PSIS - indicates SIJ involvement
What muscle weakness might indicate SIJ pathology
hip adductors
What is the clinical prediction rule for lumbar stenosis
Bilateral symptoms, leg pain worse than back pain, pain with standing, relief with sitting, age > 45 years- > 3+ is highly specific
