pelvis, hip and femur

Question 1

label the anatomy of an ap pelvis

Question 2

name the different parts of the illium

Answer 2

the iliac crests, the iliac fossa, sarco iliac joints, the anterior superior iliac spine, and the anterior inferior iliac spine

Question 3

name the different parts of the pubis

Answer 3

pubic rami, pubic arch, symphisis pubis

Question 4

name the different parts of the ischium

Answer 4

the ischial tuberosity and the ischial rami

Question 5

what is the triradiate cartilage

Answer 5

the triradiate cartilage the y shaped epiphyseal olate that separates the ischium, pubis and ilium

Question 6

describe the patient posistioning collimation and centring for an ap pelvis

Answer 6

patient is supine with legs raised of a pilow with legs extended. the asis should be equidistant from the table top with legs internally rotated to ensure that the femoral necks are parralel to the table

centering should be at the midpoint, midway between the upper border of the symphisis pubis and the asis

collimation should include the illiac crests, the greater and lesser tochanters, the proximal third of the femora

Question 7

what i s the imaging criteria for an AP pelvis

Answer 7

is all relevant anatomy demonstarated
are the obturator foramina symetrical
are the sarcoiliac joints well penetrated
any artefacts

Question 8

list the main parts of the hip joint

Answer 8

the femoral head, femoral neck, the lesser and greater trochanters, intertrochanteric line

Question 9

how would you take an AP hip

Answer 9

patient supine with legs extened. asis should be equidistant from the table and the femoral necks should be paraller to the table by internal rotation of the affected leg

centring at the femoral head 2.5 cm below the lesser trochanter with collimation including the femoral neck the acetabulum and the posterior and anterior soft tissue margins

Question 10

lateral hip

Answer 10

patient laying down suffected leg raised until the knee is flexed and the theigh is vertical
centring at the groun pine with legs extended nd msp perpendicuar to the trolly

unffaffeced leg should be rasied until the thigh is verticaland the knee should be flexed
centring at the groing
collimationto include the proximal 3rd of femur acetabullum the greater an lesser trochanter

Question 11

ap Femur

Answer 11

patient laying supine with posterior aspect of the femur in contct with the image receptor
leg internally rotated 15 degrees to esnure that the femur is in the true AP position

centring middway of the femur with collimation including the knee joint and 2 thirds of the distal femur.
