RADT316 Unit #3
| Question | Answer |
|---|---|
| Our _________ serves as a base for our trunk and a girdle for the attachment of our lower limbs. | pelvis |
| The pelvis contains what four bones: | two hip bones (innominate bones), and the sacrum, and coccyx |
| The pelvis is divided into 2 portions by a boundary line called the brim of the pelvis. Above the brim is called the: | False (greater) pelvis |
| The pelvis is divided into 2 portions by a boundary line called the brim of the pelvis. Below the brim is called the: | True (lesser) pelvis |
| The female pelvis is shaped for childbearing and delivery so it is ___________ compare to the male pelvis. | wider & shallower |
| T/F: The female pelvis’s inlet is larger and more oval or rounded shaped. | True |
| For an AP Pelvis, medially rotate both feet ________ degrees. | 15-20 |
| For an AP Pelvis, the CR should be centered to: | midway between ASIS and pubic symphysis (this is about 2” inferior to ASIS) |
| For an AP Pelvis Bilateral Frog-Leg "Modified Cleaves" the CR should be centered: | 1-inch superior to the pubic symphysis (3 inches below ASIS) |
| For an AP Outlet view, the CR angle should be __________ degree for a male and _________ degree for a female. | Males: Angle 20-35 cephalad Females: Angle 30-45 cephalad |
| For an AP Outlet view, the CR should be centered to: | 1-2 inches distal to the upper border of the pubic symphysis |
| For an AP Inlet view, the CR should be ______ degrees _______. | 40 degrees caudal |
| For an AP Inlet view, the CR should enter at the: | midline at level of ASIS |
| For an AP Oblique Pelvis (Acetabulum): Judet Method: LPO & RPO, the patient should be positioned __________ degrees oblique. | 45 |
| In the Judet view, the posterior oblique position (LPO and RPO) demonstrates the __________ (downside/upside) acetabulum and more specifically the __________ (anterior/posterior) rim of the acetabulum. | downside, anterior (ants go down in the ground) |
| In the Judet view, the anterior oblique position (LAO and RAO) demonstrates the __________ (downside/upside) acetabulum and more specifically the __________ (anterior/posterior) rim of the acetabulum. | upside, posterior (posts go up) |
| If the anterior acetabulum is of interest in the Judet view, the CR should be directed: | 2 inches distal and 2 inches medial to downside ASIS (ants go marching 2 by 2) |
| If the posterior acetabulum is of interest in the Judet view, the CR should be directed: | 2 inches distal to upside ASIS |
| The hip bone consists of what 3 bones: | Ilium, pubis, ischium (they are fused together to make up the acetabulum ) |
| The acetabulum fuses during the middle _________ years. | teenage |
| The Hip joint is a ____________ type of joint. | Synovial (synovial fluid), Diarthrodial (freely moveable), Ball and socket |
| T/F: The obturator foramen is the largest foramen in the skeletal system. | True |
| The pubic symphysis joint is classified as: | Cartilaginous joint, Amphiarthrodial (limited movement) |
| SI Joints is classified as a: | Synovial joint Amphiarhtrodial (little movement) |
| SI Joints go at a __________ degree angle from MSP. | 25-30 |
| For a unilateral AP hip, the CR should be centered: | CR 1-2 medial & 3-4 inches distal to ASIS |
| For a unilateral AP hip, the leg should be rotated internally ___________ degrees. | 15-20 |
| The femoral neck can be found by going ______ inches medial to the ASIS and ______ inches distal. | 1-2 inches medial from ASIS and 3-4 inches distal |
| In a unilateral Frog Leg radiograph, you should be able to visualize: | the acetabulum, femoral head, and the femoral neck |
| For a x-table lateral hip (Danelius-Miller Method), the IR should be __________ (parallel/perpendicular) to the femoral neck, and the CR should be _________ (paralle/perpendicular) to the femoral neck and IR. | parallel, perpendicular |
| For a Clements-Nakayama view, the grid is tilted ______ degrees from vertical and parallel with the femoral neck, and you should angle the CR mediolaterally, _______ degrees from horizontal and centered to femoral neck. | 15, 15 |
| When a patient has bilateral hip fractures or limitation of movement of the unaffected leg, the ______________ can be used to obtain a lateral view. | Clements-Nakayama |
| The Female sacrum/coccyx curve more ____________ (anteriorly/posteriorly) than males. | posteriorly |
| For AP Axial SI Joints, the CR should be centered: | 2 inches below ASIS |
| For AP Axial SI Joints, a _______ degrees cephalad for males _______ degrees cephalad for females. | 30 degrees cephalad for males, 35 degrees cephalad for females |
| For a posterior oblique SI joint (LPO or RPO), we are looking at the _____________ (upside/downside) SI joint. | upside |
| For a posterior oblique SI joint (LPO or RPO), we should elevate side of interest ___________ degrees. | 25-30 |
| For a posterior oblique SI joint (LPO or RPO), the CR should enter: | 1-inch medial to upside ASIS |
| For a anterior oblique SI joint (LAO or RAO), we are looking at the __________ (upside/downside) SI joint. | downside, “eyes down, side down” |
| For a anterior oblique SI joint (LAO or RAO), we should rotate the side of interest to table _________ degrees. | 25-30 |
| For a anterior oblique SI joint (LAO or RAO), the CR should enter: | 1-inch medial to the ASIS closest to the IR |
| The proximal femur consists of what four essential parts: | the head, neck, the greater and the lesser trochanters |
| For an AP femur Mid/Proximal, we should rotate the femur ____________ degrees medially. | 15-20 |
| if we are doing a dedicated distal AP femur, we should rotate the leg internally about _________ degrees to open the knee joint more. | 5 |
| Pathology - describe Ankylosis: | Calcification of anterior longitudinal ligament, fusion of the spine and SI joints, bamboo spine appearance (from bony outgrowths), males most affected |
| Pathology - describe Legg-Calve-Perthes Disease: | Limp is the first clinical sign, aseptic/ ischemic necrosis, flattened shape of the head of the femur, most common: 5-10 year old boys |
| Pathology - describe Chondrosarcoma: | Malignant tumor of cartilage, found in Pelvis and long bones. Treatment includes surgery, radiation/chemotherapy. Most common: Men older than 45 years |
| Lytic lesions are _____________ (radiopaque/radiolucent). | radiolucent |
| Sclerotic lesions are ___________ (radiopaque/radiolucent). | radiopaque |
| Pelvic ring fractures usually occur from: | High-force trauma (motorcycle accidents or a fall from 20 or more feet) |
| T/F: Pelvic ring fractures usually have a matching fracture at the opposite point. | True |
| Pathology - describe Avulsion Fracture: | Small pieces of bone are broken from its insertion point. It is from a sudden force of tendon or ligament being pulled forcefully |
| Tendons attach: | muscle to bone |
| Ligaments attach: | bone to bone |
