Exam 4: Chapter 42: Management of Patients with Musculoskeletal Trauma Flashcards
What is a contusion?
A soft tissue injury produced by blunt force, such as a blow, kick, or fall, causing small blood vessels to rupture and bleed into soft tissues
What develops at the site where a contusion occured?
A hematoma, leaving a characteristic “Black and Blue” appearance
Local symptoms of Contusion include
Pain, Swelling, and Discoloration; Ecchymosis
Contusions are managed with what acronym?
PRICE
Protection, Rest, Ice, Compression, and Elevation
Most contusions resolve in
1-2 weeks
What is a strain?
Injury to a muscle or tendon from overuse, overstretching, or excessive stress
Strains can be categorized as
acute or chronic
What is a first-degree stain?
Mild stretching of a muscle or tendon with no loss of range of motion
Signs of symptoms of first-degree strain?
GRadual onset of palpation-induced tenderness and mild muscle spasm
What is a second-degree strain?
Involves moderate stretching and/or partial tearing of the muscle or tendom
signs and symptoms of second-degree strain?
Acute pain during the precipitating event, followed by tenderness at the site with increased pain with ROM, edema, significant muscle spasm, and ecchymosis
What is a third-degree strain?
Severe muscle or tendon stretching with rupturing and tearing of the involved tissue
Signs and symptoms of third-degree strain?
Immediate pain described as tearing, snapping, or burning, muscle spasm, ecchymosis, edema, and loss of function
What test should be performed to test for third-degree strain?
X rays to rule out bone injury.
MRI and Ultrasound can identify tendon injury
What is a sprain?
An injury to the ligaments and tendons that surround a joint. Caused by a twisting motion or hypererxtension of a joint
Disability and Pain increase during first 2-3 hours
Ligaments connect
bone to bone
Tendons connect
muscle to bone
Function of a ligfament is to
stabilize a joint while permititng mobility
First-Degree/Mild Grade Sprain results from
tears in some fibers of the ligament and mild, localized hematoma formation
First-Degree/Mild Grade Sprain Manifestations include
Mild pain, edema, and local tenderness
Second-Degree/Moderate Grade Sprain involves
partial tearing of the ligament
Second-Degree/Moderate Grade Sprain manifestations include
increased edema, tenderness pain with motion, joint instability, and partial loss of normal joint function
Third-Degree/Severe Grade Sprain occurs when
a ligament is completely torn or ruptured. May also cause avulsion of the bone
Third-Degree/Severe Grade Sprain symptoms
severe pain, increased edema, and abnormal joint motion
How is (P)RICE accomplished?
Through support of the affected area and/or splinting
How is P(R)ICE accomplished?
Rest prevents additional injury and promotes healing
How is PR(I)CE accomplished?
Intermittent application of cold packcs during the first 24-72 hours after injury produces vasoconstriction, which decreases discomfort
Ice packs should not be placed for longer than 20 minutes
How is PRI(C)E accomplished?
Elastic compression bandage controls bleeding, reduces edema, and provides support for ithe injured tissues
How is PRIC(E) accomplished?
Elevation at or just above the level of the heart controls teh swelling
What is a dislocation?
Dislocation of a joint is a condition in which the articular surfaces of the distal and proximal bones that form the joint are no longer in anatomic alignment
What is a subluxation?
A partial dislocation that does not cause as much deformity as a complete dislocation
A sprian is what type of injury?
Tissue injury. You get swelling and you get bleeding into the tissue. That is where the bruising comes from
What is a traumatic dislocation?
An emergency with pain change in contour, axis, and length of the limb and loss of mobility
If a dislocation or subluxation is not reduced immediately, what may develop?
Avascular Necrosis (AVN).
AVN of bone is caused by ischemia, which leads to necrosis or death of the boen cells
Signs and Symptoms of a traumatic dislocation include
acute pain, change in or awkward positioning of the joint, and decreased ROM.
XRays conform the diagnosis and reveal any associated fracture
Dislocation: What is used to facilitate closed reduction?
Analgesia, muscle relaxants, and possibly anesthesia
Dislocation: The joint is immobilized by
splints , casts, or traction and is maintained in a stbale position
Dislocation: Neurovaascular status is assessed at a minimum of
every 15 minutes until stable
Dislocation: Danger Signs and Symptoms to look out for include
increasing pain, numbness or tingling, and increased edema in the extremity.
Where does a DVT occur?
In the actual vessel itself. DVT will be on bed rest for a day ro two and will be given a anticoagulant in order to break it down
For All Knee Ligaments, TEndons, and Menisci, what should you do?
PRICE.
What should you do when you sprain a knee?
Place it in a brace. No matter what is injured, you want to place it in a brace
What can you teach a patient to assess for neurovascular wise?
Wiggle fingers, Feel numbness? Warm? Feel Pain? Check for Pulse. Assess Capillary Refillq
Every joint has
tendons
What is a fracture?
A complete or incomplete disruption in the continuity of boen structure and is defined according to its type and extent
Fractures occur when
the bone is subjected to sress greater than it can absorb
Fractures may be caused by
direct blows, crushing forces, sudden twisting motions, and extreme muscle contractions
When the bone is broken, adjacent structres are also affected which may result in
soft tissue edema, hemorrhage into the muscles and joints, joint dislocations, reuptured tendons, severed nerves, adn damaged blood vessels
What is a closed (simple) fracture?
It is one that does not cause a brek in the skin
What is an open fracture (compound, or complex)
One in whicht he skin or mucous membrane would extends to the fractured bone
What is a Type I open wound?
Clean wound less than 1 cm long
What is a Type II open wound?
Larger wound without extensive soft tissue damage or avulsions
What is a Type III open wound?
Highly contaminated and has extensive soft tissue damage. May be accompanied by traumatic amputation and is the most severe
What is a intra-articular fracture?
Extends into the joint surface of a bone.
CLinical signs and symptoms of a fracture include
acute pin, loss of function, deformity, shortening of the extemity, crepitus, and localized edema and ecchymosis
Fractures: PAin is continuous and icnreases in severity until the boen fragments are
immobilized
Fractures: Immediately after a fracture, injured area becomes
numb and the surrounding muscles flaccid
Fractures: Muscle spasms that accompany a fracture begin
shortly thereafter, whthin a few to 30 minutes and result in more intesne pain
Fractures: sometimes muscle spasms can cause the distal and proximal site of the fracture to
overlap , causing the extremity to shorten
What is crepitus?
A crumbling sensation that can be felt or may be heart. It is caused by the rubbing of bone fragments against each other
Fractures: Localized edema and ecchymosis occur after a fracture as a result of
trauma and bleeding into the itissues. The signs may not develop for several hours
What is a Avulsion Fractures:
A fracture in which a fragment of bone has been pulled away by a tendon and its attaachment
What is a Comminuted Fractures:
A fracture in which bone has splintered into several fragments
What is a COmpression Fractures:
A fracture in which bone has been compressed (seen in vertebral fractures)
What is a Depressed Fractures:
A fracture in which fragments are drive inward (seen frequently in fractures of skull and facial bones)
What is Epiphyseal Fractures:
A fractures through the epiphysis
What is a Greenstick Fractures:
A fracture in which one side of a boen is broken and the other side is bent
What is a Impacted Fractures:
A fracture in which a bone fragment is driven into another bone fragment
What is a Oblique Fractures:
A fracture occuring at an angle across the bone (lesss stabele than a transverse fracture
