Break in bone from direct or indirect trauma | fracture |
fracture that runs along a slant to the length of bone | oblique |
fracture that is splintered into fragments | comminuted |
fracture that breaks coils around the bone | spiral |
fracture that is incomplete fracture, common in children | greenstick |
fracture where one bone fragment is forcibly wedged against another bone fragment | impacted |
fracture that remains contained, does not break the skin | simple |
fracture in which damage also involves the skin or mucus membranes | compound |
fracture in which bone has been compressed as seen in vertebral fractures | compression |
a pulling away of a fragment of bone by a ligament or tendon and its attachments | avulsion |
a fracture in which fragments are driven inward as seen in skull and facial bone fractures | depressed |
fracture that occurs through an area of diseased bone, can occur without trauma or a fall | pathologic |
S/S of fractures: | pain (especially when attempts are made to move or put pressure over the affected area); loss of function (muscle becomes flacid - usually 10-40 min after break); deformity; false motion; crepitus (grating sound); edema; spasm; may be bruising |
Stage 1 of fracture healing: | bleeding occurs immediately after fracture, along with edema; in 48-72 hours a hematoma forms between the two broken ends of bone |
Stage 2 of fracture healing: | Hematoma does not reabsorb. Other cells enter the clot and granulation (healing) tissue forms, gradually becoming firm and making a bridge between the two broken ends |
Stage 3 of fracture healing: | (by the end of the 1st week) granulation tissue turns into callus which is made up from cartilage, osteoblast, calcium and phosphorus; the callus is larger than the diameter of bone and acts as a splint |
Stage 4 of fracture healing: | Within 2-3 weeks, woven bone forms; ends of the broken bone begin to knit |
Stage 5 of fracture healing: | Excess bone is naturally chiseled away by stress to the affected part from motion, exercise and weight bearing; bone takes on its original shape and size |
Bone is back to its original forma after about: | 1 year |
Short term complications of fractures: | shock; fat embolism; deep vein thrombosis; compartment syndrome; risk of excessive blood loss |
Loss of blood after a fracture can cause: | hypovolemic shock |

Fat embolism usually occur: | 24-48 hours after injury |
People at highest risk for fat embolism: | older pt with a hip fracture |

Prevention of DVTs include: | anti-embolism stockings, compression devises, early ambulation |
serious complication that results from internal or external pressure on the affected area | compartment syndrome |
Muscles compartment areas are composed of: | enclosed spaces made up of muscle, bone, nerves and blood vessels wrapped in a fibrous membrane (fascia) |
Internal pressure can be caused by: | bleeding or edema into a compartment |
External pressure can be caused by: | a cast or tight dressing |
When there is bleeding or edema into a compartment, there is _____________. | nowhere for the drainage to go because it is trapped in the space. |
Increased fluid in compartment syndrom puts pressure on the tissues, nerves and blood vessels so that ____________. | blood flow is decreased, resulting in pain and tissue damage. |
Irreversible muscle damage from compartment syndrome can occur within: | 4-6 hours |
Partial paralysis caused by compartment syndrome can occur in: | 24 hours |
Complete paralysis caused by compartment syndrome can occur within: | 24-48 hours |
Primary symptom of compartment syndrome is: | pain, especially with touch or movement, that is not relieved by opioid analgesia; edema; pallor; weak or unequal pulses; cyanosis, tingling numbness and decreased movement |
once bone cells are deprived of oxygen and nutrients, they die and the cells walls collapse. This is called: | avascular necrosis |
S/S of avascular necrosis: | pain, instability, and decreased function in the affected area |
Treatment of avascular necrosis: | relieving the weight bearing and removal of part of the bone. If that fails, joint replacement may be necessary. |
improper alignment of the bone ends resulting in external deformity | malunion |
fracture never heals | nonunion |
failure of the fracture to heal in the expected time | delayed union |
Delayed union can be treated by: | electrical stimulation; bone grafts; synthetic material that stimulates bone growth |
process of bringing the ends of the broken one into proper alignment | reduction |
nonsurgical realignment of the bones that is usually done with some form of anesthesia and a cast is usually applied afterwards | closed reduction |
surgical procedure where the bones are realigned; usually done for commuted or open fractures | open reduction |
an attempt to attach the fragments of the bone together when reduction alone is not feasible because of the type and extent of the break | fixation |
fixation that includes the use of rods, pins, nails, screws, or metal plates to align the bone fragments and keep them in place for healing | internal fixation |
fixation similar to internal fixation but the pins in the bones are attached to an external frame | external fixation |
types of casts: | plaster of paris; fiberglass; thermopastic resins; thermolabile plastic; polyester-cotton knit impregnanted with polyurethane |
