TRAUMATIC INJURIES
4 classifications of fractures
open (compound)
closed (simple)
complete / incomplete (greenstick)
comminuted and compressed (spinal)
TRAUMATIC INJURIES
A fracture where bone breaks through the skin and can be seen outside the leg.
Open (compound)
TRAUMATIC INJURIES
A fracture where there is no opening in the skin but there is a break in the continuity of the bone inside.
Closed (simple)
TRAUMATIC INJURIES
A fracture where there is a complete break of the bone
Complete
TRAUMATIC INJURIES
A fracture where a bone bends and breaks but does not separate into two separate pieces; Only one part of the bone is damaged, not completely broken
Incomplete (greenstick)
TRAUMATIC INJURIES
A fracture where it is very common in elderly because of osteoporosis, sudden movement generates a break in the bone and compression in the nerves
Compressed (spinal)
TRAUMATIC INJURIES
horizontal break in the bone
Transverse
TRAUMATIC INJURIES
angle break in the bone
Oblique
TRAUMATIC INJURIES
spiral/break in the bone that turns around
Spiral
TRAUMATIC INJURIES
divides bone into two large pieces
Segmental
TRAUMATIC INJURIES
one part of the bone attached to the tendon and because of too much
pressure, a part of the bone is removed due to the force of the tendon
Avulsed
TRAUMATIC INJURIES
there’s also a break but because of too much pressure, instead of separating, from the bone, it was pushed further
Impacted
TRAUMATIC INJURIES
very fine fracture, also known as buckle fractures, are incomplete fractures of the shaft of a long bone that is characterized by bulging of the cortex as it heals (belt-shaped)
Torus
Musculoskeletal Care Modalities:
Used to immobilize a reduced fracture; Correct deformity/support and stabilize weakened joints

can be defined as having two splits, in such a way as to leave a resting gutter for the injured limb.
bivalved surgical cast
Musculoskeletal Care Modalities:
Contoured splints of plaster or pliable thermoplastic materials may be used for conditions that do not require rigid immobilization, for those in which swelling may be anticipated, and for those that require special skin care.
Splinting

Do nurses perform closed reduction?
No
Musculoskeletal Care Modalities:
BOARD EXAM QUESTION:
Interventions for applying cast include:
-Support extremity or body part to be casted.
-Support cast during hardening/drying with palms of
hands
-Leave cast uncovered and exposed to air (casts are
usually air dried)
-Encourage passive ROM exercise of joints not
casted (finger exercises) to maintain joint flexibility,
prevent contractures, and prevent muscle atrophy
-Observe for signs of infection
-Monitor circulation, motion, sensation

Tractions
Musculoskeletal Care Modalities | Tractions
Uses only bandages; Not an invasive procedure
Skin Traction
Musculoskeletal Care Modalities | Tractions
It is often used when continuous traction is desired to immobilize, position, and align a fracture of the femur, tibia, and cervical spine; Invasive procedure because it requires an incision of the skin (uses pins such as Steinmann pins), screws, or wires) longer-term traction requiring heavier weights.
Skeletal Traction
Musculoskeletal Care Modalities | Tractions
an external appliance that provides support, prevents or corrects joint deformities, and improves function; reduces the effects of weight-bearing on the body, or prevent movement of a joint or limb in a given
direction.
Orthopedic Brace
Musculoskeletal Care Modalities | Tractions
involves passing a metal pin or wire through the bone under local
anesthesia, avoiding nerves, blood vessels, muscles, tendons, and joints.
Skeletal Tractions

prescribed for short-term use to stabilize a fractured leg, control muscle spasms, and immobilize an area before surgery.

exposure of the fracture
Open Reduction
Musculoskeletal Care Modalities
Stabilization of the reduced fracture by the use of metal screws, plates, wires, nails, and pins
Internal fixation
Musculoskeletal Care Modalities
Replacement of all or part of the joint surface just like damages in ligaments or cartilage - uses titanium to lessen the reject of the body from the for ring material.
Arthroplasty
Musculoskeletal Care Modalities
immobilizing fusion of a joint where fracture cannot work as an
individual bone so this procedure will fuse it all together, movement will be affected (cannot be bent anymore) but can be the best way to save the case.
Arthrodesis
Musculoskeletal Care Modalities
incision and diversion of the muscle fascia, if there’s the possibility of
compartment syndrome where too much inflammation decreases the blood supply/circulation in that area or distal to the injury, ______will be done.
Fasciotomy
