Question 1

disorders of skeletal system

Answer 1

Fractures, Dislocations, Sprains/Strains, osteoporosis, Rickets/Osteomalacia, Paget Disease, Joint Disorders , Bone Tumors

Question 2

fractures

Answer 2

-Breaks in the rigid structure of the bone
-Most common traumatic musculoskeletal disorder
-Causes: falls, motor vehicle accidents, sports-related injuries, and conditions that weaken the bone (e.g., osteoporosis, Paget’s disease, and bone cancer)
-Can be Complete (broken into pieces) or Incomplete (partially broken)

Question 3

open fracture

Answer 3

-skin is broken & bone may protrude out of the skin
-Causes more damage to soft tissue and increases risk for infection

Question 4

closed fracture

Answer 4

skin is intact

Question 5

simple fracture

Answer 5

a single break with bone ends maintaining their alignment and position

Question 6

comminuted fracture

Answer 6

multiple fracture lines and bone pieces

Question 7

greenstick fracture

Answer 7

-an incomplete break in which the bone is bent and only the outer curve of the bend is broken
-Commonly occurs in children because of minimal calcification, and often heals quickly

Question 8

compression fracture

Answer 8

bone is crushed or collapses into small pieces

Question 9

stress fracture

Answer 9

-occurs from repeated excessive stress
-Common in the tibia, femur, and metatarsals

Question 10

fracture complications

Answer 10

-Delayed union, malunion, or nonunion may occur due to poor nutrition, inadequate blood supply, and premature weight bearing

Question 11

compartment syndrome (fracture complication)

Answer 11

-a serious condition that results from increased pressure in a compartment
-Pressure impinges on the nerves and blood vessels present within the compartment, potentially compromising the distal extremity
-Manifestations: excruciating pain that is beyond what would be expected given the injury
