What is a Incomplete fracture? | Bone breaks through only one cortex |
What is a Greenstick fracture? | Incomplete fracture one side of a bone is broken and the other side is bent, primarily occur in children |
What is a Complete fracture? | the fracture line extends entirely through the bone, through both cortices, with periosteum disrupted on both sides of the bone |
What is a Comminuted fracture? | the bone is splintered into three or more small fragments at the fracture site with the bone ends separated and usually misaligned |
What is an Impacted (Buckle) fracture? | One bone fragment is forcibly wedged into another. Common in children. |

What is an Oblique fracture? | a slanted fracture of the shaft along the bone's long axis |
What is a Spiral fracture? | (torsion fracture) break coils around the bone |
What is a Colles Fracture? | fracture- fractures of the distal portion of the radius within 1 inch of the joint of the wrist, commonly occurs from the attempt to break a fall by putting the arms down |
What is a Potts Fracture? | fracture at the distal end of the fibula, chipping off a piece of the medial malleolus with a displacement of the foot outward |
How long after fracture does the callus form? | 6-10 days |
The blood clots and fibrin network that forms between the fractured bone ends changes into what? | Granulation tissue |
What is used to determine presence or absence of pulse in a fracture PT? | Doppler device |
What is closed reduction? | manual manipulations, moving bony fragments into position by applying traction and pressure to distal fragments |
What is an Open reduction with internal fixation (ORIF)? | surgical procedure allowing fracture alignment under direct visualization using various internal fixation devices applied to the bone |
What is maxillomandibular fixation (MMF)? | Wiring of the jaw shut in Tx of fractures |
What is Mandibular Reduction Internal Fixation? | wires and/or screws and plates are placed in the bony segments of the jaw to hold them in their correct relationship |
For a PT who received surgery for a mandibular fracture, what should be taped to the head of the patient’s bed and tied to a string around the patient's neck when they are OOB? | Wire cutters |
What is a Intermedullary rod (kuntscher nail)? | A metel rod that is placed in the (intramedullary shaft) center of the femur bone with wires around the bone for stabilization in Tx of hip fractures |
How should the bed be placed for a PT with a post-operative hip fracture? | HOB is elevated a maximum of 45 degrees to avoid acute flexion of the hip and strain on the fixation device |
Why should a post-op hip fracture PT not cross his/her legs? | crossing the legs can adduct the affected extremity and dislocate the hip |
How often should post-op hip fracture PT be rotated, and how? | Turn patient q 2 hours per MD orders. This can be accomplished by using log rolling procedure with the assistance of two nurses.( A pillow is placed between the legs to maintain abduction while rolling) |
What is a Burst Fracture? | an injury to the spine in which the vertebral body is severely compressed in all directions |
What is a Compression Fracture? | An injury to the spine where the vertibrae is only crush on one side and becomes wedge shaped |
When my pain from a spinal fracture NOT be present? | if fracture has altered the spinal cord |
What is a Halo Brace? | A "halo" metal ring is secured to the skull with pins and to two metal rods attached to a well-fitted plastic jacket |
How long will a PT with a pelvic fracture be on bed rest? | 3 weeks |
How long will a PT with a pelvic fracture require crutches? | 6 weeks |
How long will a PT with a pelvic fracture have to ambulate without weight bearing? | 3 months |
Compartment syndrome be treated with a fasciotomy within how long before nerve and muscle ischemia results in permanent damage? | 12-24 hours |
How often must vital signs be completed with a PT in shock? | q15 min |
Within how long after injury can gas gangrene set in? | 1-14 days |
What bacteria is involved in gas gangrene? | Clostridium bacteria - C. perfringens (anaerobic). |
What are the S/Sx of gas gangrene? | *Pain- sudden/severe *Toxic delerium *Skin gas bubbles *Crepitation *Foul odor |
What is the medical/surgical management of gas gangrene? | *Establish a larger wound to admit air to promote drainage *Antibiotic- PCN, Keflin |
The affected area of a thromboembolus feels how on palpation (Objective and Subjective)? | Affected area become cold, numb and cyanotic |
A Thromboebolus of the lung causes what S/Sx? | *sudden, sharp thoracic or upper abdominal pain *dyspnea *fever *cough *hemoptysis |
What fractures is a thromboembolus a high risk for? | Pelvic and Hip |
What device is used in Tx of Infected fractures and infected unstable joints? | Skeletal pin external fixation |
How often are pins in a Skeletal pin external fixation device cleaned, and with what? | 1 to 2 times daily with hydrogen peroxide or alcohol, using surgical asepsis |
How long should a PT who recieved a cast keep the affected limb elevated to reduce the chances of edema? | 24-48 hours |
A PT who just received a cast tells you that it feels very warm, almost hot. What should you as a nurse do? | Inform the PT that its normal for a cast to feel warm or hot as it dries, and that once dried it will end. |
How long does it take a fiberglass cast to dry? | Dries immediately |
How long does it take a plaster cast to dry? | 24-48 hours |
True or False: The abductor bar is placed in a spica cast to aid in turning and moving of the PT. | False. The abductor bar is placed to keep the extremity in a functional position while healing. Do NOT grasp it. |
How will the skin under the cast appear once the cast is removed? | mottled and it may be covered by a yellow crust composed of exudate, oil, and dead skin |
True or False: When handling a fresh undry cast you are incouraged to use only your fingertips to reduce pressure on the cast. | False. That increases the chances of causing indentations and thus pressure. You must use your palms and/or pillows to reduce the chance of indentation. |
What are the two types of fracture? | Skeletal and skin |
What are the three types of skin traction? | Buck’s, Russell’s, and Bryant’s |
How much traction weight can be safely applied for skin traction, and how long? | Only 5 to 10 lbs of force can safely be applied to the patient's skin for a period of 3 to 4 weeks |
What is Bucks traction? | Straight traction on the leg while the leg is flat on the bed. |
What is Russells traction? | Distal leg elevated parallel to bed with knee flexed and straight traction of foot. |
What is Bryants traction? | Legs raised perpendicular to bed with traction pulling up |
What skin traction is a temporary measure to maintain the reduction of a hip fracture before surgery? | Bucks traction (Bucks extension) |
What is the skin traction used in pediatrics for small children with fractured femurs? | Bryants traction |
What are inserted into the skull and provides traction in cases of fracture of the cervical spine? | Crutchfield tongs |
