Musculoskeletal Trauma

Question 1

Self-Healing of Bones

Answer 1

swelling of soft tissue and the formation of blood clot in the are of the break or fracture
Interruption of the blood supply causes death to the cells at the injury site
cells farther from the fracture remain intact and rapidly divide growing together to form a mass of tissue completely surrounding the fracture site. this may take weeks or months depending on the bone fractured, type of fracture, and health and age

Question 2

Cartilage

Answer 2

connective tissue that covers the outside of the bone end (epiphysis)and acts as a surface for articulation, allowing for smooth movement at joints
less rigid forms and helps to form some of the more flexible structures of the body

Question 3

Tendons

Answer 3

bands of connective tissue that bind the muscles to bones

allow for the power of movement across the joints

Question 4

Ligaments

Answer 4

connect tissues that support joint by attaching the bone ends and allowing for a stable range of motion

Question 5

MTB

Answer 5

muscle-tendon-bone

Question 6

BLB

Answer 6

bone-ligament-bone

Question 7

Traction splint

Answer 7

splint that applies constant pull along the length of a lower extremity to help stabilize the fracture bone and to reduce muscle spasm in the limb
used primarily on femoral shaft fractures

Question 8

Anticipated blood loss

Answer 8

pelvic fracture 3-4 pints
femur fracture 2 pints
tibia-fibula fracture 1 pint

Question 9

Fracture

Answer 9

any break in a bone

Question 10

comminuted fracture

Answer 10

fracture in which a bone is broken in several places

Question 11

Greenstick Fracture

Answer 11

an incomplete fracture (crack)

Question 12

Angulated fracture

Answer 12

fracture in which the broken bone segments are at an angle to each other

Question 13

Dislocation

Answer 13

disruption or “coming apart” of a joint

Question 14

Sprain

Answer 14

stretching and tearing of ligaments

Question 15

strain

Answer 15

muscle injury resulting from overstretching or overexertion of the muscle

Question 16

Compartment Syndrome

Answer 16

injury caused when tissues such as blood vessels and nerves are constructed within a space as from swelling or from a tight dressing or cast

Question 17

Crepitus

Answer 17

grating sensation or sound made when fractured bone ends rub together

Question 18

Splinting

Answer 18

For any splint to be effective, it must immobilize adjacent joints and bone ends

Question 19

Manual traction

Answer 19

the process of applying tension to straighten and realign a fracture limb before splinting
