Trauma Patients Flashcards
Bones
Hard, but flexible, living structures that provide support for the body and protection for vital organs
Axial Skeleton
Skull, sternum, ribs, spine
Appendicular Skeleton
Bones in the upper extremities (clavicles, scapula, arms, wrist, hands) & lower extremities (pelvis, thighs, legs, ankles, feet)
Periosteum
Strong, white, fibrous substance that covers bones
Mechanisms of musculoskeletal injury
Direct force, indirect force, or twisting/rotational force
Traction splint
A splint that applies constant pull along a lower extremity to help stabilized the fractured bone and reduce muscle spasm of the limbs
Comminuted fracture
A fracture where the bone is broken in several places
Greenstick fracture
An incomplete fracture
Angulated fracture
Fracture in which the bone segments are at an angle with each other
Dislocation
Disruption or “coming apart” of a joint (ligaments are stretched and torn beyond normal range of motion)
Sprain
Stretching & tearing of ligaments
Strain
Injury caused by overstretching and/or overexertion of the muscle
Closed extremity injury vs. Open extremity injury
Skin is not broken in closed extremity injury, skin is broken in open extremity injury (by injured bone or penetrating object)
Compartment Syndrome
Treatment & Stages
Injury caused when tissues such as blood vessels & nerves are constricted within a space as from swelling or tight dressing or cast. Treatment includes cold application and elevation of extremity after splinting.
Stages:
- Fracture or injury causes bleeding and swelling within extremity
- Pressure and swelling caused by the bleeding within the muscle compartment becomes so great that the body can no longer perfuse against the pressure
- Cellular damage causes additional swelling
- Blood flow to the area is lost. If not relieved, limb may be amputated
Crepitus
A grating sensation or sound when fractured bone ends rub together
The “Six Ps,” Indicating Musculoskeletal Injury
- Pain or tenderness
- Pallor (Pale skin, poor cap refill)
- Paresthesia (Pins & needles sensation)
- Pulses diminished or absent (at injured extremity)
- Paralysis
- Pressure
Emergency Care for Musculoskeletal Injuries
- Standard Precautions
- Primary Assessment (Don’t be distracted by gross injury)
- Secondary Assessment (Trauma), Apply C-spine collar if injury suspected.
- After life threatening conditions have been addressed, injured extremities can be realligned (when necessary) & splinted.
- Stable patient: Splint before transport
- Unstable patient: Immobilize on long spine board & splint specific injuries en route
- If appropriate, cover open wounds with sterile dressing, elevate affected extremity, apply cold pack
Manual traction
The process of applying tension to straighten and realign a fractured limb before splinting. Should only be applied when limb is cyanotic and distal pulse is not present.
Anterior hip dislocation
The patient’s entire limb is rotated outward and the hip is usually flexed
Posterior hip dislocation
Most common type; Patient’s leg is rotated inward, the hip is flexed, and the knee is bent. Foot hangs loose, unable to flex. Often lack of sensation in limb is present, indicates nerve damage.
Hip fracture vs. Pelvic fracture
Hip fracture is a fracture of the proximal femur, pelvic fracture is a fracture of the pelvis
Kinetic Energy=
[Mass * (Velocity)^2]/2
Knee dislocation vs. Patella dislocation
Knee dislocation occurs when the tibia is forced anteriorly or posteriorly in relation to the femur. A patella dislocation occurs when lower leg and knee are dislocated.
Multiple trauma verus Multisystem trauma
Multiple trauma= more than one serious injury
Multisystem trauma= more than one injury that affects more than one body system
