Hip Stuff
hip stuff from notes i got out the book
| Question | Answer |
|---|---|
| Angle of inclination | femur shaft conncevted to the head of femor by femoral neck, about 125 in frontal plane change during growth, it is decreased in women |
| Coxa Valga | increase in the angle of inclination |
| Coxa Vara | decrease in the angle of inclination |
| angle of torsion | in the transverse plaine relationship between femoral had and shaft, usually about 15* |
| Anteversion | increase in the angle of torsion |
| retroversion | decrease in angle of torsion |
| Iliofemoral ligament | y shaped ligament of bigelow-O:ant inf illia spine, I:distal aspect ant intertrocanteric line &prox ant intertrocanteric line/fem. neck, reinforces ant joint cap, sup fibers limit ABD, inf fibers limit ADD, allows to stand up right w/ minimal muscularwork |
| Pubofemoral ligament | enforces ant capsule, O:pubic ramus, I:ant aspect of intertrocanteric fossa, limits ABD and hyper extension |
| ischiofemoral ligament | supports post joint capsule, O:post acetabulum rim w. upward spiraling fibers attaching to the joint capsule & inner surface of greater trocanter, limits hip ext |
| Ligamentum teres | "ligament of the head of the femur" conduit for med/lat circuflex ateries, little function in hip stabalizing |
| Inguinal ligament | O:ASIS, I:pubic symphysis, superior boarder of the femoral triangle |
| Anterior Musculature | rectus femoris-hip/knee flex, sartorius-knee/hip flex ABD ER, Iliopsoas-psoas major/minor, iliacus, primary hip flexor when knee is flexed, all rotate pelvis ant on sacrum as they contract, tightness of them can cause SI stress causing ant rot of pelvis |
| Medial Musculature | mainly ADD & IR hip, Adductor group: ADD longus, magnus, brevis, aided by pectineus & gracillis |
| Lateral Musculature | most superficial-flute med&TFL, TFL-ABD&IR Deep 6-6intrinsic muscles-piriformis, quadratis femoris, obdurator internis, obdurator externis, gemellis sup/inf-ER hip |
| Posterior Musculature | glute max-mass of butt-hip ext especially w/ knee flex, hamstring muscle group-hip ext/knee flex, responsible for decelerating knee ext/hip felx during dec. in running, if tight can cause post rot of pelvis |
| Femoral Triangle | superior boarder inguinal ligament, lateral bor satorius, medial border ADD longus, contains femoral art/nerve/vein, lymph nodes, palpate femoral pulse here |
| Bursae | trochanteric bursa, gluteofemoral bursa, ischial bursa |
| Trochanteric Bursa | lubricates spot where glute max passess over greater trochanter |
| Gluteofemoral bursa | seperates glute mad from bastis lateralis at their origins |
| Ischial Bursa | weight bearing structure when seated, cushipons ischial tuberosity under glute max |
