Orthopedics Flashcards
Cast
A rigid external immobilizing device made of fiberglass or plaster of Paris
Short-arm cast
Extends from below the elbow to the palmar crease, secured around the base of the thumb. If the thumb is included, it is known as a thumb spica or gauntlet cast
Long-arm cast
Extends from the axillary fold to the proximal palmar crease; the elbow usually is immobilized at a right angle
Short-leg cast
Extends from below the knee to the base of the toes; the foot is flexed at a right angle in a neutral position
Long-leg cast
Extends from the junction of the upper and middle third of the thigh to the base of the toes; the knee may be slightly flexed
Walking cast
A short or long-leg cast reinforced for strength
Body cast
Encircles the trunk
Shoulder spica cast
A body jacket that encloses the trunk, shoulder and elbow
Hip spica cast
Encloses the trunk and a lower extremity; a double hip spica cast includes both legs; typical 4-6 weeks
Uses of casts
Immobilize reduced fracture
Correct deformity
Apply uniform pressure to soft tissues
Support/stabilize weak joints
Splint
Contoured splints made of plaster or pliable thermoplastic
Uses of splint
Conditions that do NOT require rigid immobilization
Anticipated swelling
Those who require special skin care
Simple & stable fractures
Sprains
Tendon injuries
Soft tissue injuries
Brace
Custom fitted device (i.e. orthoses)
Uses of brace
Provide support
Control movement
Prevent additional injury
Patient care BEFORE application of cast/splint/brace
Assess general health, emotional status
Assess presenting signs and symptoms and condition of area
Give tetanus shot if wound dirty or last boost >5 years ago
Sterile dressing for the wound
Monitor and assess neurovascular status for potential complications
Treat any lacerations and abrasions before application
Explain purpose of treatment to patient
Explain procedure of application (sounds, sights, sensations)
Continual care with cast/splint/brace
Monitor neurovascular status using 6 Ps Q1-4H for first 24 hour
Monitor and treat pain (elevation, ice pack, analgesics)
Apply ice packs over fracture site for 1-2 days
Elevate leg to level of heart for first 24-48 hours
Lower extremity immobilization (patient in recumbent position to promote venous return)
Assess bowel sounds Q4-8H if have a body cast
7 Ps of neurovascular status checks
Pain
Poikilothermia
Pallor
Pulselessness
Paresthesias
Paralysis
Puffiness
Patient education of Cast/splint/brace
Impact of injury on ADLs
Activity, exercise rest
Medications
cast drying techniques
Controlling swelling and pain
Care of minor skin irritation
Cast removal
Date & time of next f/u appt
Conditions to report to provider
Compartment syndrome
Increased pressure in a confined space compromises blood flow that can cause ischemia and irreversible damage within hours
Pressure ulcer
Pressure ulcer occurs due to inappropriately applied case or too tight bandage; can cause tissue anoxia and ulcers and necrosis
Disuse Syndrome
Muscle atrophy and loss of strength
Infection
More common in an open wound and the moist/warm environment of splint/cast can facilitate the infection
S/s of compartment syndrome
1st indication - pain
7 Ps
Increased intra-compartmental pressure
Treatment of compartment syndrome
Notify surgeon
Cast may be removed/loosened
Emergency fasciotomy
Do NOT lift extremity higher than level of heart to maintain arterial perfusion
