HIP Flashcards
HIP - ROM
- Flexion - 80-90 (straight leg)
- Flexion - 120 (bent leg)
- Extension - 30
- Internal rotation - 40
- External rotation - 50
- Abduction - 50
- Adduction - 30
HIP - MYOTOMES
- Hip flexion - L1, L2, L3 - femoral nerve
- Knee extension - L3, L4 - femoral nerve
- Knee flexion - L4, L5, S1, S2 - sciatic nerve
- Ankle dorsiflexion - L4, L5 - deep peroneal nerve
- Ankle inversion - L4, L5 - tibial nerve, deep peroneal nerve
- Ankle eversion - L5, S1 - superior peroneal nerve
- Big toe extension - L5, S1 - deep peroneal nerve
- Big toe flexion - L5, S1 - tibial nerve
HIP - ORTHO TESTS - SCREENING
- SCREENING - Heel walk, toe walk, Trendelenburg’s sign
HIP - ORTHO TEST - INSTABILITY
- INSTABILITY - hip telescoping
HIP - ORTHO TEST - HIP DJD
- HIP DJD - Scour, FABERE
HIP - ORTHO TEST - LUMBAR RADICULOPATHY
- LUMBAR RADICULOPATHY - SLR, Braggard’s test
HIP - ORTHO TEST - HIP FLEXOR LENGTH
- HIP FLEXOR LENGTH - Thomas test, Gaenslen’s test, Rectus femoris contracture test
HIP - ORTHO TEST - PIRIFORMIS SYNDROME
- PIRIFORMIS SYNDROME - Sign of the buttock
HIP - JOINT TYPE
Synovial
- Symphysis - pubic symphysis
- Ball and socket - acetabulofemoral
HIP - ARTICULAR SURFACES
- Acetabulofemoral - convex (head of femur) on concave (acetabulofemoral)
HIP - MAIN MUSCLE ACTIONS - FLEXION
- FLEXION - iliopsoas, rectus femoris, sartorius
HIP - MAIN MUSCLE ACTIONS - EXTENSION
- EXTENSION - gluteus maximus, hamstrings
HIP - MAIN MUSCLE ACTIONS - ABDUCTION
- ABDUCTION - gluteus medius, gluteus minimus, tensor fasciae latae
HIP - MAIN MUSCLE ACTIONS - ADDUCTION
- ADDUCTION - adductor Magnus, gracilis, adductor longus and brevis
HIP - MAIN MUSCLE ACTIONS - INTERNAL ROTATION
- INTERNAL ROTATION - gluteus medius, gluteus minimus, tensor fasciae latae
HIP - MAIN MUSCLE ACTIONS - EXTERNAL ROTATION
- EXTERNAL ROTATION - piriformis, quadrates femoris, superior and inferior gemellus, obturator internus and externus
HIP - RESTING POSITION
Acetabulofemoral: 30 abduction, 30 flexion, and slight external rotation
HIP - CLOSED PACKED POSITION
Acetabulofemoral: full extension, abduction and internal rotation
HIP - NORMAL END FEEL
FLEXION & ADDUCTION- elastic or tissue approximation
EXTENSION & ABDUCTION - elastic/firm
STRAIGHT LEG RAISE - elastic
INTERNAL/EXTERNAL ROTATION - elastic/firm
HIP - ABNORMAL END FEEL
- Bony = osteoarthritis
- Late myospasm = instability
HIP - HIP JOINT FORCES
- Standing - 0.3x body weight
- Standing on one leg - 2.5x body weight
- Walking - 3x body weight
- Running - >4.5x body weight
HIP - CONDITIONS - AVASCULAR NECROSIS
Hx - repetitive hip trauma, corticosteroids, alcohol, diabetes, sickle cell anaemia, atherosclerosis
S&S - pain/stiffness in hip joint, pain persists with rest, antalgic limp, limited ROM
DDx - osteoarthritis, osteoporosis, hip dislocation, femoral neck fracture
HIP - CONDITIONS - ACETABULAR LABRAL TEAR
Hx - prior trauma, deep hip/groin pain, worse with full hip flexion, possible locking
S&S - audible click with motion, pain with full passive hip flexion (bent knee)
DDx - internal or external snapping hip, DJD
HIP - CONDITIONS - HERNIA (INGUINAL OR FEMORAL)
Hx - M>F (9:1); prior heavy lifting with valsalva causes more pain
S&S - palpable protrusion worse with valsalva - Red flags: nausea, fever, vomiting, discolouration indicative of a strnagulated hernia = medical emergance
DDx - groin strain, testicular torsion
