Musculoskeletal Flashcards
Trendelenburg Gait
The Trendelenburg gait pattern is an abnormal gait (as with walking) caused by weakness of the abductor muscles of the lower limb, gluteus medius and gluteus minimus.
Osteotomy
Cutting of and removal of bone to improve bone function
Arthrotomy
Cutting into a joint to expose its interior
Hematogenously
Involving, spread by, or by arising in the blood
When does fusing and maturing of epiphyseal region occur?
Adolescence
Why do infants have bowed legs?
From the positioning in utero. Resolves in 2-3 years with weight bearing
Casting
Immobilizes a bone that has been injured or a diseased joint, holds a bone in reduction when a fracture has occurred, and prevents/corrects deformities
What are casts usually made of?
Plaster or fiberglass - drying time varies.
** Be careful to not make indentations during drying time
How do you make a cast waterproof?
Gore-Tex lining
Neurovascular Assessment for Casts
- Pulse
- Paresthesias
- Pallor
- Paralysis
- Pain
What do you monitor for to prevent compartment syndrome?
- Increased pain
- Increased edema
- Cyanosis or pallor
- Coolness of skin
- Numbness or tingling
- Prolonged cap refill
- Decreased or absence of pulse
When can you use ice for patient with a cast?
Only in the first 24-48 hours
What should you teach your patient about cast care?
- Wiggle fingers or toes hourly
- Itching technique
- Protect from wetness
- When to call HCP
How to alleviate an itch under a cast
- Never insert anything into the cast
- Blow cool air on hair dryers lowest setting
- No lotions or powder
How can a parent check for skin irritation of their child that has a cast?
- Press the skin back around the edges of the cast
- Use a flashlight to look for reddened or irritated areas
- Feel for blisters or sores
When to call HCP for a patient with a cast?
- Cool extremities (or color change)
- If the child can’t move the fingers or toes
- Severe pain when moving fingers or toes
- Persistent numbness or tingling
- Drainage or foul odor
- Severe itching
- Fever greater than 101.5 for longer than 24 hours
- Skin edges are red and swollen or exhibit breakdown
- The cast gets wet and does not dry or is cracked, split, or softened
Skin Care After Cast Removal
- Brown, flaky skin is normal and occurs as dead skin and secretions accumulate under the cast
- New skin may be tender
- Soak with warm water daily
- Wash with warm soapy water, avoiding excessive rubbing, which may traumatize the skin
- Discourage the child from scratching the dry skin
- Apply moisturizing lotion to relieve dry skin
- Encourage activity to regain strength and motion of extremity
Traction
Application of weights to provide pulling force on an extremity or body part for reducing fractures, realigning injured extremities, decreasing muscle spasms, and correcting deformities
Skeletal Traction
- Apply weights via ropes attached to skeletal pins
- Protect exposed ends of pins to avoid injury
Skin Traction
- Apply weights via ropes to bandage or foam boot
- Apply traction over intact skin only
Nursing Consideration for Traction
- Ensure ropes move freely and weights do not touch floor.
- Constant and even traction should be maintained.
- Promote use of trapeze if not contraindicated to involve the child in repositioning and assist with movement
- Encourage deep-breathing exercises to prevent the pulmonary complications of long-term immobilization
Fixation
Surgical reduction of complicated fracture or skeletal deformity with an internal or external pin or device used to immobilize bone while it heals
Pin Care
- Perform pin care weekly after the first 48 to 72 hours. Perform earlier if large amounts of drainage is present, dressing becomes wet, or infection is suspected
- Use chlorhexidine or normal saline
- Use a nonshedding material for cleaning
- Cover pin sites with a nonshedding dressing
- Teach children and their families pin site care along with instructions on the signs and symptoms of infection before discharge
Types of Skin Traction
- Bryant
- Russell
- Buck
- Cervical
- Side Arm 90-90
Bryant Traction
Type of Skin Traction
- Used to reduce femur fracture in children younger than 2 years or with developmental dysplasia of the hip (DDH)
Bryant Traction Nursing Considerations
- The buttocks are slightly elevated and clear of the bed
- Assess bandages and skin every shift
- Ensure ankles and heels are free from pressure
Russell Traction
Type of Skin Traction
- Traction for femur fracture, hip, and specific types of knee injuries or contractures
Russell Traction Nursing Considerations
- Ensure heel is free from bed
- Use a foot support to prevent foot drop
- Assess popliteal region for skin breakdown from the sling
- Mark leg to ensure proper replacement of sling
Buck Traction
Type of Skin Traction
- Skin traction for hip and knee contractures, Legg-Calve-Pethes disease, slipped capital femoral epiphysis
- Used to rest an injured limb or to prevent spasms
Buck Traction Nursing Considerations
Remove traction boot every 8 hours to assess skin
Cervical Skin Traction
Type of Skin Traction
- Traction applied with a skin strap (head halter)
- Used for neck sprains/strains, torticollis, or nerve trauma
Cervical Skin Traction Nursing Considerations
Ensure that head halter or skin strap does not place pressure on ears or throat
Side Arm 90-90
Type of Skin Traction
- Traction for humerus fractures and injuries in or around the shoulder girdle
Side Arm 90-90 Nursing Considerations
- Fingers and hand may feel cool because of elevation
- Child may turn to affected side only
Types of Skeletal Traction
- Dunlop side arm 00-90
- 90-90
- Cervical skeletal tongs
- Halo
- Balanced suspension
Dunlop Side Arm 00-90
Type of Skeletal Traction
- Skeletal traction through an olecranon screw or pin in distal humerus
Dunlop Side Arm 00-90 Nursing Considerations
Provide appropriate pin site care
90-90 Traction
Type of Skeletal Traction
- For femur fracture reduction when skin traction is inadequate
- Skeletal traction with force applied through pin in distal femur
90-90 Traction Nursing Considerations
Provide appropriate pin site care
Cervical Skeletal Tongs
Type of Skeletal Traction
- Tongs attached to skull via pins for fractures or dislocations of cervical or high thoracic vertebrae
- Special bed required
Cervical Skeletal Tongs Nursing Considerations
Assess frequently for increased pain, respiratory distress, and spinal cord, cranial nerve, or brachial plexus injury
Halo Traction
Type of Skeletal Traction
- Metal halo attached to skull via pins for cervical or high thoracic vertebrae fractures or dislocations or postoperative immobilization after cervical fusion
Halo Traction Nursing Considerations
- Tape small wrench to front of brace so that front panel can be quickly removed in an emergency
- May become ambulatory in this type of traction; will be top-heavy so may need assistance with balance
- Assess pin sites and provide pin care as ordered
Balanced Suspension
Used for femur, hip, or tibial fracture
Balanced Suspension Nursing Considerations
Avoid pressure to popliteal area
Pectus Excavatum
Funnel shaped chest, sinks inward at the xiphoid process
- Progresses with growth
Pectus Excavatum Treatment
May require surgery (preferable before puberty if cardiac or pulmonary compression occurs
- SOB
- Exercise intolerance
- Chest pain
Pectus Carinatum
Protuberance of chest wall, pigeon chest
Post Operative Nursing Considerations for Pectus Excavatum
- Do not allow the child to roll in bed, lie on either side, or rotate or flex the spine (these positions may disrupt the bar’s position)
When is the pectus excavatum bar removed?
2-4 years after initial placement
Limb Deficiencies
- Absence of a limb or portion of it, or the deformity of a limb
- Occurs during fetal development
Limb Deficiency Cause
Amniotic bands
Limb Deficiency Treatment
- Provide activities early to improve child’s function and activities that the child can participate in
- PT/OT
- May need prosthesis
Polydactyly
Extra digits
- Assess for presence of bone
- May require surgery or simply tying off with suture (necrosis)
