hip

hip

head of femur joins acetabulum of pelvis

ligaments of hip, pelvis, and thigh

iliofemoral, ischiofemoral, pubofemoral

hamstring muscles

semimembranosus, semitendinosus, bicepfemoris

action of hamstrings

knee flexion and hip extension

gluteal muscles

gluteus maximus, gluteus medius, gluteus minimus

gluteus maximus movement

hip extension, external rotation

gluteus medius & minimus movement

hip abduction, internal rotation

groin muscles

gracilis, adductor magnus, adductor longus, pectineus

goin muscle movement

adducts and internal rotation of thigh

quadriceps muscles

rectus femoris, vastus lateralis, vastus medialis, vastus intermedius

quadriceps movement

knee extension

hip flexor muscles

rectus femoris, sartorius, iliopsoas

which muscle responsible for knee extension and hip flexion

rectus femoris

muscle that abducts hip

tensor fascia latae

IT Band

tight connective tissue, connects hip muscles to lower leg

IT Band syndrome

tight IT band pulls where tendon attaches to bone, pain in lateral knee

avulsion fractures

forceful muscle contraction pulls bone away

growth plate fractures

capital femoral epiphysis, head of femur slips off neck, pain in groin hip knee,

stress fractures

running oriented athletes, caused by repetitive stress, pounding force of lower extremity while running

femur fractures

internal bleeding, swelling, tearing of muscle tendon nerve or arteries

hip dislocations

leg often internally rotated

hip pointer

contusion to iliac crest of pelvis, caused by direct blow to side of hip/pelvis

thigh contusion

common especially in collision sports, can cause tissue tearing and extensive bleeding

develops when contusion is not managed properly, formation of bone tissue w/in muscle

myositis ossificans

disruption of blood flow to head of femur causing tissue to die head of femur collapse and become flat

legg-calve perthes disease

labral tears

clicking locking hip/groin pain

positive test: involved leg raises off the table and lower leg moves into extension

thomas test

implications: tightness in hip flexors

thomas test

positive test: athlete does not attempt to lift leg and examiner does not sense pressure from the uninvolved leg pressing down on hand

hoover's test

implications: athlete not attempting to perform test (faking the injury)

hoover’s test

positive test: pain arising from the SI joints

SI Compression and distraction test

implications: sacroiliac pathology

SI compression and distraction test

positive test: pelvis lowers on the non weight bearing side

trendelenburg's test

implications: weak gluteus medius muscles

trendelenburg’s test

positive test: pain in the SI joint or hip

faber’s test

implication: hip and SI joint pathology

faber’s test

what are they massaging?

IT band

what injury is this?

hip dislocation

what injury is this

legg-calve perthes disease
