Question | Answer |
---|---|
illiofemoral ligament | O:a.i.i.s. I:itertrochanter A: limits hyperextension |
pubofemoral ligamnet | O: medial part of acetabulum I: neck of the femur A: limits hyperextension, and abduction |
ischial femoral ligament | O: ischial portion of the acetabulum I: femoral neck A: limits hyperextension and medial rotation. |
ligamentum teres (intracapsular ligament) | O: proximal acetabulum I:distally in femoral head A: tight during adduction and lateral rotation |
Iguinal ligament | O: a.s.i.s. I: pubic tubercle |
Rectus femoris | O:a.i.i.s. I: tibial tuberosity N:femoral A: hip flexion knee extension |
IT band | O: anterior illac crest I: tibia, runs into tensor fascia late and gluteux maximus N:femoral nerve A: hip flexion |
Sartorius | O: a.s.i.s. I:proximal medial side of the tibia (pessanserine) N:femoral A: hip flexion, knee extension, adbuction, lateral rotation |
semitendinosus | O: ischial tuberosity I: anteromedial surface of proximal tibia (pess) N: sciatic A: extend hip and flex knee |
semimembranous | O: ischial tuberosity I:posterior surface of the medial condyle of tibia N: sciatic A: extends hip and flexes knee |
pectineus | O: superior ramus of the pubis I: pectineal line N: femoral A:hip flexion and adduction |
gracilis | O:pubis I:anterior medial surface of proxmial tibia (pess) N: obturator A: hip adduction |
adductor brevis | O: pubis I: pectineal line and proximal linea aspera N: obturatot A: hip adduction |
adductor longus | O: pubis I: mid third of linea aspera N: obturator A: hip adduction |
adductor magnus | O: ischium and pubis I: entire linea aspera and adductor tubercle N: obturator and sciatic nerve A: hip adduction |
gluteus maximus | O:posterior surfave of illium and post. infer. surface of sacrum and coccyx I: posterior femur distal to greater trochanter N: inferior gluteal A: hip extension, hyperextension, lateral rotation |
gluteus medius | O: outer surface of ilium I: lateral surface of greater trochanter N: superior gluteal nerve A: hip abduction |
gluteus mini | O: lateral ilium I: anterior surface of greater trochanter N: superior gluteal A: hip abduction and medial rotation. |
illiopsoas (illiacus + psoas major) | o: illiac fossa, anterior lat. of t12-l5 I:lesser trochanter A: prime hip flexion N: femoral |
hip pointer | contusion to a.s.i.s. , p.s.i.s, iliac crest |
avulsion Fx: | a.s.i.s. (sartorious a.i.i.s. (rectus femorus) ischial tuberosity (hammy) |
stress Fx(periosteitis) | the bone covering becomes inflamed |
osteopubitis | inflammation of pubic synthesis. chronic pain often long distance runners |
Adolescent problems | Osgood schlatter and legg calves perthes |
Osgood schlatter | apophesitis of tibial tuberosity |
legg claves perthes | avascular necrosis of the femoral head |
slipped femoral capitis | head of femur breaks. the head remains in acetabulum and femur slips out |
Bursaes | Greater trochanter, and ischial |
piriformis syndrome | causes ridiculopathy from pinched siatic nerve |
angle of torsion | occurs in transverse plane: retroversion(duck foot) antiversion (pigeon toed) |
angle of inclination | occurs in frontal plane: coxa vara (femoral head up) coxa valga(femoral head down) |
degree of hip flexion | 125 |
degree of hip extension | 10-15 |
degree of internal rotation/external rotation | 45 |
degree of abduction | 45 |
degree of adduction | 40 |
Muscles that o: ischial tuberosity | semimembranous, semitendinous |
Muscles that o: pubis | gracilis, adductor brevis, adductor longus, adductor magnus, pectineus |
