Term
What are the four soft tissue injuries that are commonly caused by trauma?
Definition
Sprains, strains, dislocations, subluxations.
Term
What are the two most common types of injury affecting the musculoskeletal system? Where do they tend to occur?
Definition
Sprains and Strains, tend to occur around joints and in spinal musculature.
Term
What is a sprain?
Definition
A sprain is an injury to the ligamentous structures surrounding a joint, usually caused by a wrenching or twisting motion (usually in ankle or knee joints).
Term
What is a strain?
Definition
A strain is an excessive stretching of a muscle, its fascial sheath, or a tendon that usually occur in the large muscle groups (low back, calf, hamstrings).
Term
What are the clinical manifestations of sprains and strains?
Definition
Pain (aggravated by continued use), edema, decrease in function, and contusion.
Term
True or False? Mild sprains and strains are usually self-limiting, with full function returning within 3 to 6 weeks.
Definition
True. Need to do x-rays and RICE.
Term
True or False? Severe strains may require surgical repair of the muscle, tendon, or surrounding fascia.
Definition
True
Term
What is the acute intervention for sprains and strains?
Definition
RICE (rest, ice, compression, elevation) has been found to decrease local inflammation and pain for most musculoskeletal injuries.
Term
When should ice be applied after a musculoskeletal injury and how long should ice application last?
Definition
Cold is most useful when applied immediately after the injury has occurred. Ice applications should not exceed 20 to 30 minutes per application, and ice should not be applied directly to the skin.
Term
Why is compression important in the treatment of a sprain or strain?
Definition
Compression helps limit swelling, which, if left uncontrolled, could lengthen healing time.
Term
When would warm, moist heat be used for a sprain or strain? How long should each application occur?
Definition
After the acute phase (usually 24 to 48 hours), warm, moist heat may be applied to the affected part to reduce swelling and provide comfort. Heat applications should not exceed 20 to 30 minutes allowing a “cool-down” time between applications.
Term
What is a dislocation?
Definition
A dislocation is a severe injury of the ligamentous structures that surround a joint. Dislocation results in the complete displacement or separation of the articular surfaces of the joint.
Term
What is subluxation?
Definition
A subluxation is a partial or incomplete displacement of the joint surface.
Term
What is the most common manifestation of a dislocation?
Definition
Deformity
Term
Besides deformity, what are some other manifestations of a dislocation?
Definition

Local pain

Tenderness

Loss of function of the injured part

Swelling of the soft tissues in the region of the joint

Term
What two diagnostic studies are done with a dislocation?
Definition
  • X-ray - determine extent of displacement of structures
  • Joint Aspiration - determine presence of hemarthrosis or fat cells. Fat cells in aspirate indicate a probable intraarticular fracture.

 

Term
True or False? A dislocation is considered an orthopedic emergency.
Definition
True. The longer the joint remains unreduced, the greater the possibility of avascular necrosis (bone cell death as a result of inadequate blood supply).
Term
What is the first goal of dislocation management?
Definition

The first goal of management is to realign dislocated portion of joint in its original anatomic position.

This can be accomplished by a closed reduction, which may be performed under local or general anesthesia or intravenous (IV) conscious sedation. Open reduction via surgery is needed in some cases.

Term
Why would general anesthesia be used in a closed reduction of a dislocation?
Definition
Anesthesia is often necessary to produce muscle relaxation so the bones can be manipulated.
Term
Besides realignment of the joint, what are three other important Nursing Indications for treatment of a dislocation?
Definition
  • Pain control
  • Immobilization of joint
  • Gentle ROM as ordered
Term
What medication is commonly used for conscious sedation during a closed reduction?
Definition
Versed
Term
What are some manifestations of a rotator cuff injury?
Definition

 

  • Shoulder weakness
  • Pain - especially when arm is abducted between 60 and 120 degrees (the painful arc)
  • Decreased ROM
  • Drop Arm Test - arm falls suddenyl when patient's arm is abducted 90 degrees and asked to lower arm slowly
Term
True or False? If a patient has a complete tear in the rotator cuff, surgical repair may be necessary.
Definition
True
Term
A sling, or more commonly, a shoulder immobilizer may be used immediately after surgery of a torn rotator cuff to limit shoulder movement. Why is it important to limit the time the shoulder is immobilized?
Definition

The shoulder should not be immobilized for too long because “frozen” shoulder or arthrofibrosis may occur.

 

Pendulum exercises and physical therapy begin the first postoperative day.

Term
Although there is no significant edema with a torn meniscus because the cartilage is avascular, what manifestations WOULD you see?
Definition
  • Localized tenderness
  • Pain with flexion, internal rotation, & extension of knee
  • Effusion
  • "click", "pop", "lock", "give way"
Term
What is the acute care of a meniscus injury?
Definition
  • Must be examined within 24 hours
  • Application of ice
  • Immobilization - knee brace/immobilizer first few days
  • Weight bearing as tolerated with crutches

 

Term
What do patients commonly report when explaining an ACL injury?
Definition
Patients often report coming down on the knee, twisting, and hearing a pop, followed by acute knee pain and swelling.
Term
What is conservative treatment of an intact ACL injury?
Definition
  • Rest
  • Ice
  • NSAIDs
  • Elevation
  • Ambulation as tolerated with crutches
  • If there is a tight, painful effusion, it may be aspirated
  • Knee immobilizer or hinged knee brace for support of knee
  • Physical Therapy

 

Term
How long is the return to the patient's prior level of functioning after reconstructive surgery of a severe ACL injury?
Definition
6-8 months
Term
What is Bursitis?
Definition

Inflammation of the bursa from repeated or excessive trauma or friction, gout, rheumatoid arthritis, or infection.

 

Note: Bursae are closed sacs that contain a small amount of synovial fluid and are located at sites of friction, such as between tendons and bones and near the joints.

Term
What are the four primary manifestations of bursitis?
Definition
  • Warmth
  • Pain
  • Swelling
  • Limited ROM in the affected part
Term
True or False? Rest is often the only treatment needed for bursitis.
Definition

True.

 

Note: may also use ice/NSAIDs to decrease pain/inflammation, compression dressing or splint to immoblize, corticosteroid injection, aspiration of bursal fluid, surgery if septic bursae or wall has become thickened

Term
What is a fracture?
Definition
A break or disruption in the continuity of a bone
Term
Explain these terms related to fractures: open, closed, complete, incomplete, displaced, and nondisplaced.
Definition
  • Open/Compound - through skin/bone & soft tissue exposed
  • Closed/Simple - not through skin/intact skin
  • Complete - break is completely through bone
  • Incomplete - bone in one piece/break across shaft
  • Displaced - two ends of a broken bone are separated and out of their normal positions
  • Nondisplaced - periosteum intact and bone still in alignment
Term
Explain a transverse fracture.
Definition
Transverse fracture is a fracture in which the line of the fracture extends across the bone shaft at a right angle to the longitudinal axis (straight across horizontally).
Term
Explain a spiral fracture.
Definition
Spiral fracture is a fracture in which the line of the fracture extends in a spiral direction along the shaft of the bone.
Term
Explain a greenstick fracture.
Definition
Greenstick fracture is an incomplete fracture with one side splintered and the other side bent.
Term
Explain a comminuted fracture.
Definition
Comminuted fracture is a fracture with more than two fragments. The smaller fragments appear to be floating.
Term
Explain an oblique fracture.
Definition
Oblique fracture is a fracture in which the line of the fracture extends in an oblique direction (diagonal).
Term
Explain a pathologic fracture.
Definition
Pathologic fracture is a spontaneous fracture at the site of a bone disease.
Term
Explain a stress fracture.
Definition
Stress fracture is a fracture that occurs in normal or abnormal bone that is subject to sudden force or repeated stress, such as from jogging or running.
Term
What are the common manifestations of a fracture?
Definition
  • Edema and swelling
  • Pain and tenderness
  • Muscle spasm
  • Deformity - may not be obvious
  • Echymosis or contusion
  • Loss of function
  • Crepitation
  • Patient guarding extremity
Term
What should be done immediately if a fracture is suspected?
Definition
Immoblize extremity to decrease risk of further soft tissue damage that would convert a closed fracture to an open fracture.
Term
How do you diagnose most fractures?
Definition
Simple x-ray
Term
How would you diagnose fractures in more complex structures like hip, pelvis, or spine?
Definition
CT Scan
Term
How would you diagnose small bone fractures or fractures from stress or disease?
Definition

Bone Scan

(shows inflammatory process as well)

Term
What are the six stages of bone healing?
Definition
  • Fracture Hematoma - bleeding creates a hematoma  within 72 hours
  • Granulation Tissue - phagocytosis absorbs products of necrosis and produces basis for new bone (3-14 days)
  • Callus Formation - forms initial bone matrix, made of cartilage, osteoblasts, calcium, phosphorous, magnesium (verified by x-ray)
  • Ossification of callus - 3 weeks to 6 months (cast may be removed with limited mobility allowed)
  • Consolidation - distance between bone fragments reduces as callus continues (up to 1 year)
  • Remodeling - union is complete

 

Term
Why is unchecked bleeding, swelling, and edema so dangerous after a fracture?
Definition
Could occlude circulation and damage nerves (risk of compartment syndrome).
Term
True or False? Ecchymosis may appear immediately after fracture and may appear distal to injury. 

Definition
True
Term
True or False? Fracture healing time decreases with age.
Definition
False, fracture healing time increases with age.

Term
List 8 factors that affect fracture healing.
Definition
  • Age
  • Displacement of fracture
  • Site of fracture
  • Blood supply to area
  • Immoblization
  • Implants
  • Infection
  • Hormones
Term
What is closed reduction?
Definition

Closed reduction is a nonsurgical, manual realignment of bone fragments to their previous anatomic position.

 

After reduction, traction, casting, external fixation, splints, or orthoses (braces) immobilize the injured part to maintain alignment until healing occurs.

Definition

15 minutes

(not strong enough for weight bearing until 24-72 hours)

Term
True or False? You should use the tips of your fingers when handling a newly molded cast.
Definition
False, you should use an open palm to avoid denting the cast.
Term
Immobilization of an acute fracture or soft tissue injury of the upper extremity is often accomplished by use of (1) the sugar-tong splint, (2) posterior splint, (3) the short arm cast, and (4) the long arm cast. Explain what each of these is used for.
Definition
  • Sugar-tong splint - acute wrist injuries or injuries that result in swelling (wrapped with elastic or stockinette)
  • Posterior splint - accommodates swelling
  • Short arm cast - stable wrist or metacarpal fractures (immobilization with unrestricted elbow motion)
  • Long arm cast - stable forearm or elbow fractures and unstable wrist fractures (restricts elbow and wrist movement)

Term
What is cast syndrome?
Definition
Body cast is applied too tightly and patient complains of abdominal pain, abdominal pressure, nausea, and vomiting.
Term
What must we assess if a patient has a body jacket cast?
Definition

Must assess for decreased bowel sounds, respiratory status, bowel and bladder function, and areas of pressure over the bony prominences, especially the iliac crest

 

 

Term
How is cast syndrome treated?
Definition
Treatment includes gastric decompression with a nasogastric (NG) tube and suction. The cast may need to be removed or split.
Term

Term
What is the short leg cast primarily used for?
Definition
Stable ankle and foot injuries.
Term
What is a cylinder cast used for?
Definition
Knee injuries or fractures. The cast extends from the groin to the malleoli of the ankle.
Term
True or False? A Jones dressing is composed of bulky padding materials (absorption dressing and cotton sheet wadding), splints, and an elastic wrap or bias-cut stockinette.
Definition
True
Term
How long should a lower extremity be elevated above the level of the heart after having a cast or dressing put on?
Definition

For the first 24 hours

 

Note:

Term
True or False? It is ok to place acasted lower extremity in a dependent position after the initial phase.
Definition
False. After the initial phase, the casted extremity should not be placed in a dependent position because of the possibility of excessive edema.
Term
What is an external fixator?
Definition
An external fixator is a metallic device composed of metal pins that are inserted into the bone and attached to external rods to stabilize the fracture while it heals.
Term
Why is Internal fixation preferred for older adults?
Definition

It allows early mobilization

 

Term
What is extremely important to monitor for and teach your patient with external fixation?
Definition
Monitor for infection and teach patient prevention measures to avoid infection at home including meticulous skin care.
Term
What can you do for a patient with external fixation in order to allow them to comfortably ambulate early?
Definition
Give pain medication.
Term
Are nurses allowed to change the weight on traction?
Definition
No, the physician/NP must do it
Term
True or False? It is important to make sure the traction weights do not hit the floor.
Definition
True
Term
What kinds of activities, if allowed by physician, should a patient in traction be performing several times a day to offset problems associated with immobility?
Definition
  • Frequent position changes
  • ROM exercises of unaffected joints (preferred activity)
  • Deep-breathing exercises
  • Isometric (resistance) exercises of uninvolved extremities
  • Use of the trapeze bar (if permitted) to raise the body off the bed for linen changes and use of the bedpan

 

Term
What is the difference between skin and skeletal traction?
Definition
  • Skin traction - uses light weights (5-10 lb), short term, tape boots or splints
  • Skeletal traction - heavier weights (5-45 lb), used longer, pins or wires inserted into bone
Term
What is countertraction?
Definition
The force pulling in opposition of the traction to prevent patient from sliding to end or side of bed. Usually supplied by patient's body weight or raising foot of bed.
Term
