chapter 13 Flashcards
what is the main shaft in the bone known as?
diaphysis
which of the following fractures is caused by axial compression, bending, and torsion?
oblique fracture
which of the following fractures is characterized by a bone fragment that has been pulled away from the bone?
avulsion fracture
which of the following mechanisms causes a transverse fracture?
bending
what degree classification of a ligament sprain involves total tearing of tissue?
third degree
which of the following complications is a result of repeated blows to the same area?
myositis ossificans
How long does treatment of a hamstring commonly take?
6-8 weeks
Which of the following conditions occurs 12 hours after injury and is most intense after 24 to 48 hours?
DOMS
Which of the following is the key to treating tendonitis?
resting the injured area by eliminating the irritation activity
What type of fracture is characterized by an incomplete break in a bone that has not completely ossified?
greenstick fracture
which of the following is the most common site for osteoarthritis?
all of the above
During which phase of the healing process do phagocytic cells clean up the area?
inflammatory
which of the phases may take several years to complete?
maturation
which of the phases involves scar formation and repair?
fibroblastic
which cells lay down new bone tissue?
osteoblasts
which of the following would be considered an acute injury?
shoulder subluxation
which of the following conditions is characterized by pain and discomfort during and immediately following exercise?
acute onset muscle soreness
what type of injury occurs when a bone comes partially out of its normal articulation then goes right back into place?
subluxation
fractures occur as a result of extreme stresses and strains that are placed on bones.
T
In the periosteum, osteoblasts provide nutrients to the bone; blood vessels provide cells for bone growth.
F
A stress fracture resulting from repeated micro-trauma commonly occurs in weight bearing bones.
T
A first time dislocation should be considered and treated as a fracture.
T
A strain involves damage to a ligament, and a sprain involves damage to a muscle
F
Increased muscle tension through strengthening can help stabilize the joint sufficiently to compensate for the loss of stability in a third degree sprain
T
The two most commonly contused muscle are the quadriceps and the biceps group
T
Tenosynovitis is the inflammation of the tendon sheath causing the sliding tendon to adhere to the synovial sheath
T
Any process that changes the mechanics of a joint can eventually lead to osteoarthritis
T
During the fibroblastic phase, injured cells will release chemicals that facilitate the healing process
F
Bending strain occurs parallel to the length of the bone where compressive and tensile force are present
T
A trigger point is a tight band of muscle occurring in the neck and upper back
