Study These Flashcards
A

Pathologic fracture

25
A fracture that remains contained and does not break the skin.
Simple fracture
26
A fracture twisting around the shaft of the bone.
Spiral fracture
27
A fracture that is straight across the bone.
Transverse fracture
28
What is a common clinical manifestation of a fracture?
* Pain * Loss of function * Deformity * Shortening * Crepitus * Swelling & discoloration
29
Restoration of the fragments into anatomic alignment and rotation.
Reduction
30
Holding fragments in correct anatomical alignment until union and bone healing occurs.
Immobilization
31
What are some nursing management strategies for patients with fractures?
* Encourage exercises of unaffected extremities * Teach safe use of assistive devices * Monitor for complications * Encourage high-protein, high vitamin diet
32
What complications can arise from fractures?
* Shock * Fat Embolism Syndrome * Compartment Syndrome * Deep Vein Thrombosis * Pulmonary Emboli * Delayed Union * Non-Union * Avascular Necrosis of the Bone * Reflex Sympathetic Dystrophy Syndrome * Heterotrophic Ossification
33
What is the purpose of a cast?
To immobilize a reduced fracture, correct a deformity, and stabilize weakened joints.
34
What are the contraindications for using a cast?
* Pregnancy * Skin disease * Swelling/edema * Open wound * Infection
35
What is the role of splints?
Used for conditions that do not require rigid immobilization and for those that require special skin care.
36
What are braces used for?
To provide support, control movement, and prevent additional injury.
37
What are external fixators used for?
To manage open fractures with soft tissue damage.
38
The application of a pulling force to a part of the body to reduce or maintain alignment of bone fragments.
Traction
39
What types of traction are there?
* Skin Traction * Buck's Extension Traction * Russell's Traction * Dunlop's Traction * Skeletal Traction
40
What are the goals of traction?
* Reduce anxiety * Achieve comfort * Encourage mobility * Prevent complications
41
May be hypovolemic or traumatic, which results from hemorrhage.
Shock
42
Due to that fat ❖ globules near the site of the injury that may move into the blood stream, combining with platelets to form an emboli.
Fat Embolism Syndrome
43
A complication that ❖ develops when tissue perfusion in the muscles is less than that required tissue viability.
Compartment Syndrome
44
Occurs when healing does not advance at a normal rate for the location and ❖ type of fracture.
Delayed Union
45
Results from failure of the ends of the fractured bone to unite.
Non-Union
46
Occurs when the bone loses its blood supply and dies. It may follow fracture with a disruption of the blood supply.
Avascular Necrosis of the Bone
47
Indicated by pain and decreased function, experienced after the fixators removed; other responses include allergic response, local inflammation.
Reaction to Internal Fixation Devices
48
An uncommon, painful sympathetic nervous system problem. Often seen more in women, occurring in an extremity after trauma.
Reflex Sympathetic Dystrophy Syndrome
49
(Myositis Ossification): the abnormal formation of bone near bones or in muscle in response to soft tissue trauma after an injury.
Heterothrophic Ossification
