Flashcards in Musculoskeletal Trauma Deck (19):
1

Self-Healing of Bones

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

2

Cartilage

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

3

Tendons

bands of connective tissue that bind the muscles to bones
allow for the power of movement across the joints

4

Ligaments

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

5

MTB

muscle-tendon-bone

6

BLB

bone-ligament-bone

7

Traction splint

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

8

Anticipated blood loss

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

9

Fracture

any break in a bone

10

comminuted fracture

fracture in which a bone is broken in several places

11

Greenstick Fracture

an incomplete fracture (crack)

12

Angulated fracture

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

13

Dislocation

disruption or "coming apart" of a joint

14

Sprain

stretching and tearing of ligaments

15

strain

muscle injury resulting from overstretching or overexertion of the muscle

16

Compartment Syndrome

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

17

Crepitus

grating sensation or sound made when fractured bone ends rub together

18

Splinting

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

19

Manual traction

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