fracture

 [frak´chur]
1. the breaking of a part, especially a bone.
2. a break in continuity of bone; it may be caused by trauma, twisting due to muscle spasm or indirect loss of leverage, or by disease that results in osteopenia. See illustration.
Types of fractures.
Treatment. Immediate first aid consists of splinting the bone with no attempt to reduce the fracture; it should be splinted “as it lies,” which means supporting it in such a way that the injured part will remain steady and will resist jarring if the victim is moved. Later it will be treated by reduction, which means that the broken ends are pulled into alignment and the continuity of the bone is established so that healing can take place. Fracture healing is truly a process of regeneration. Fractures heal with normal bone, not with scar tissue. Closed reduction is performed by manual manipulation of the fractured bone so that the fragments are brought into proper alignment; no surgical incision is made. Open fractures are highly contaminated and must be débrided and copiously irrigated in the operating room. A fracture may also require internal fixation with pins, nails, metal plates, or screws to stabilize the alignment. Once closed reduction is accomplished, the bone is immobilized by application of a cast or by an apparatus exerting traction on the distal end of the bone.

TRACTION APPLIED TO A FRACTURE OF THE LOWER EXTREMITY
2. A break of a bone. See: illustration

Causes

Fractures may be due to pathology, direct violence, indirect violence, or muscular contraction. In a pathological fracture, bones break, spontaneously and without trauma, due to certain diseases and conditions like cancer, osteomalacia, syphilis, and osteomyelitis, In a fracture due to direct violence, the bone breaks at the spot where the force was applied, as in fracture of a crushed tibia. In a fracture due to indirect violence, the bone is fractured by a force applied at a distance from the site of fracture and transmitted to the fractured bone, as a fracture of the clavicle by a fall on an outstretched hand. In a fracture due to muscular contraction, the bone breaks from a sudden, violent contraction of the muscles.

Signs

Signs include loss of the power of movement, pain with acute tenderness over the site of fracture, swelling and bruising, deformity and possible shortening, unnatural mobility, and crepitus or grating heard when the ends of the bone rub together.

Treatment

Immediate first aid includes splinting of the fracture site and joints above and below it to limit further movement and displacement. Applying a cold pack to the fracture site and elevating it above the level of the heart may limit pain and swelling. Radiography should be used to identify the fracture and the exact position of the bone fragments.

The physician reduces the fracture. The bone is kept in position by a cast or splint until union has taken place. Afterwards the limb is restored to complete function by physical therapy and exercise.

In open or compound fractures, bleeding must be arrested before the fracture is treated. Initially, the open fracture should be covered with a clean or sterile dressing and the fracture site immobilized. Open reduction may be required. The wound is then washed and cleaned with sterile saline. If the area is grossly contaminated, mild soap solution may be used provided it is thoroughly washed away with generous amounts of sterile saline. When the wound is clean, a sterile dressing is secured by a bandage. The bone may then be immobilized by external fixation until the wound heals.

Skeletal traction may be used instead of a cast or external fixator for certain fractures, such as femoral shaft fractures. Pins are placed in the bone, and the bone ends are held in place by pulleys and weights until union occurs.

If the bone does not heal, a weak electric current applied to the bone ends (bone stimulation) may promote healing. Hip fractures require gentle handling and immobilization to prevent displacement of the fracture, aggravation of bleeding, or disruption of a pelvic hematoma. Open reduction with internal fixation may be required and is performed when the patient is judged to be hemodynamically stable.

CAUTION!

First aid for fractures of the spine requires extreme care in moving the patient. Unnecessary or improper movement may injure or even transect the spinal cord. Stabilizing the patient on a rigid board, with full spinal protection, is necessary until x-ray studies reveal the spine is stable.

Patient care

Vascular and neurological status of the limb distal to the fracture site are monitored before and after immobilization with traction, casting, or fixation devices. Pain is assessed and managed with prescribed analgesics and noninvasive measures. All procedures and related sensations are explained, and reassurance given.

The patient is evaluated for fat embolism after long bone fractures, for infection in open fractures, for excessive blood loss and hypovolemic shock, and for delayed union or nonunion during healing and follow-up. The patient should report signs of impaired circulation (skin coldness, numbness, tingling, discoloration, and changes in mobility) and is taught how to care for the cast or splint and the correct use of assistive devices (slings, crutches, walker). ; illustration

TYPES OF FRACTURES AND TERMINOLOGY

avulsion fracture

The pulling away of the bony attachment site of tendons, ligament, joint capsule, or fascia. Avulsion fractures of tendons are usually caused by a forceful contraction of the muscle. Ligamentous avulsions are caused by forcing the joint beyond its normal range of motion and are often associated with sprains or dislocations.
illustration

bend fracture

Plastic deformation of bone.

Bennett fracture

See: Bennett fracture

bimalleolar fracture

A fracture of the medial and lateral malleoli of the ankle joint.

blow-out fracture

See: orbital blow-out fracture

blow-up fracture

A fracture of the bony orbit above the eye. It may result in entrapment of the superior rectus muscle with a consequent inability to gaze downward.

bowing fracture

A bending or curving fracture of a bone (usually of the forearm) due to a traumatic load that compresses the bone along its long axis.

boxer's fracture

A fracture of the distal end of the fourth or fifth metacarpal with posterior displacement of the proximal structures. The injury usually occurs after a punch is thrown with a unprotected fist.

buckle fracture

Torus fracture.

See: compression fracture

chauffeur's fracture

A colloquial term for a fracture of the radial styloid with the carpal joint.

childhood accidental spiral tibial fracture

Abbreviation: CAST
Toddler's fracture.

fracture of clavicle

Physical injury of the clavicle sufficient to fracture it, often as a result of a fall on an outstretched arm (from a ladder or bicycle) or direct impact to the bone. Most clavicular fractures involve the distal one third of the bone.

Symptoms

Symptoms include swelling, pain, and protuberance with a sharp depression over the injured bone. Palpable deformity and crepitus are commonly present.

Treatment

If indicated, an emergency care physician or an orthopedist will reduce the fracture. This usually is done by elevating the arm and lateral fragment so they line up with the medial fragment. The position is maintained by a clavicle strap, spica cast, immobilizing sling, or figure-of-eight wrap between the shoulders and over the back. Healing takes from about 6 to 8 weeks.

First Aid

A ball of cloth or one or two handkerchiefs are tightly rolled and placed under the armpit. An arm sling is applied and the elbow bandaged to the side, with the hand and forearm extending across the chest. Alternatively, the patient may lie on his or her back on the floor with a rolled-up blanket under the shoulders until medical aid arrives. This position keeps the shoulders back and prevents the broken ends of the bone from rubbing.

clay shoveler's fracture

A colloquial term for a fracture of the base of the spinous process of the lower cervical spine associated with sudden flexion of the neck. It may also be caused by direct trauma.

closed fracture

A fracture of the bone with no skin wound.

Colle fracture

See: Colles, Abraham

comminuted fracture

A fracture in which the bone is broken or splintered into pieces.

complete fracture

A fracture in which the bone is completely broken (i.e., neither fragment is connected to the other).

complicated fracture

A fracture in which the bone is broken and has injured some internal organ, such as a broken rib piercing a lung.

compound fracture

A fracture in which fragments of bone protrude through the skin or in which there is a break in the skin or soft tissue at the fracture site. Such a fracture exposes the wound to possible infection. Synonym: open fracture

compression fracture

A fracture of a vertebra by pressure along the long axis of the vertebral column. Such fractures, which may occur traumatically or as a result of osteoporosis, are marked by loss of bone height.

curbstone fracture

dislocation fracture

A fracture near a dislocated joint. See: dislocation

double fracture

Two fractures of the same bone.

Dupuytren fracture

See: Dupuytren, Baron Guillaume

Duverney fracture

See: Duverney, Joseph G.

fissured fracture

A narrow split in the bone that does not go through to the other side of the bone.

flexion-teardrop fracture

An unstable fracture of the cervical spine in which a small fragment of the anteroinferior corner of a vertebral body avulses from the rest of the vertebra due to massive flexion applied to the cervical spine. Patients with this fracture have sustained injuries to all the spinal ligaments and usually severe spinal cord injury and quadriplegia.

fragility fracture

A fracture that occurs in a bone weakened by osteoporosis.

greenstick fracture

A fracture in which the bone is partially bent and partially broken, as when a green stick breaks. It occurs in children, esp. those with rickets. There is a compression fracture on the concave side of the bend and a tension fracture on the convex side.

hairline fracture

A minor fracture in which all the portions of the bone are in perfect alignment. The fracture is seen on a radiograph as a very thin line lying between the two segments and not extending through the bone.

hangman's fracture

A bipedicular fracture of the second cervical vertebra, often with a concomitant dislocation of the vertebra. The term originates from properly performed judicial hangings. At the moment when the dropped criminal fully extends the rope, the hangman's knot causes fracture dislocation of the upper cervical spine and transection of the spinal cord or medulla. If the knot is not made or applied properly, death is usually due to asphyxia. Contemporary hangman's fractures occur mostly in automobile accidents or athletic competitions.

hip fracture

A fracture of the proximal portion of the femur, i.e., of either the head, neck, intertrochanteric or subtrochanteric regions of the hip. Hip fracture occurs each year in approximately 225,000 Americans over 50. It is more common in women than in men due to osteoporosis and is esp. common in slender, elderly women. Mortality rates after hip fracture are influenced by the patient's age, general physical health, and the type of fracture.

Etiology

Osteoporosis predisposes an elderly person to hip fracture.

Symptoms

Pain in the knee or groin is the classic presenting sign of a hip fracture. If the femur is displaced, shortening and rotation of the leg may be present.

Treatment

Preoperatively, Buck's traction may be used in the short term to alleviate muscle spasms. An open reduction is the preferred surgical treatment. A femoral prosthesis may be used for femoral neck or head fractures. The bone takes 6 to 12 weeks to heal in an elderly patient.

Patient care

During hospitalization, general patient care concerns apply. The patient is prepared physically and emotionally for surgery according to the orthopedic surgeon's protocol, and postsurgical care and pain control (epidural or intravenous patient-controlled analgesia [PCA]) is discussed. Neurovascular status of the affected limb is assessed according to protocol and compared to the unaffected limb. The patient is referred for physical and occupational therapy and uses a walker until the bone is completely healed. Prevention and relief of pain and monitoring of postoperative complications, including infection, hip dislocation, and deep venous thrombosis or pulmonary embolism, are primary concerns. Use of an incentive spirometer is encouraged to prevent atelectasis and respiratory complications. Prophylactic antibiotics and anticoagulants are administered as prescribed, and hip precautions are implemented to prevent dislocation. These precautions include having the patient avoid hip adduction (usually by an abductor wedge), rotation, and flexion greater than 90° during transfer and ambulation activities, and by using a raised toilet seat and semi-reclining chair. The patient is typically hospitalized for 2 to 4 days and then discharged to a nursing home, subacute unit, transitional care unit, rehabilitation center, or home for rehabilitation for several weeks.

A fracture in which the pubic symphysis is broken apart, e.g., in a high-speed, front-end automobile crash. The pelvis can separate in the front even though it remains held in place posteriorly by the spine or posterior ligaments.

overriding fracture

Overriding.

pathological fracture

A fracture of a diseased or weakened bone caused by a force that would not have fractured a healthy bone. The underlying disease may be a metastasized cancer, primary cancer of the bone, or osteoporosis.

Patient care

The limbs and joints of at-risk patients are gently and carefully supported when repositioning, exercising, or mobilizing. If such patients fall or are injured, and report limb, pelvic, or back pain or inability to bear weight, the patient and the affected limb should be stabilized and - diagnostic imaging obtained.

pelvic fracture

Fracture of one of more of the bones of the pelvis, i.e. of the ilium, ischium, or pubis. Pelvic fractures occur after falls, esp. in the elderly, in whom the pelvic bones may be weakened by osteoporosis, and after high-impact trauma, e.g., motor vehicle crashes. Some pelvic fractures are accompanied by internal organ damage, esp. to the genitourinary organs. Regaining the ability to walk after pelvic fracture sometimes requires months of rehabilitation.

penile fracture

Sudden trauma to the tunica albuginea of the penis, resulting in a rupture of the corpus cavernosum and sometimes a tearing of the urethra. The injury typically occurs during sexual intercourse (or, less often, during masturbation) and may be accompanied by bleeding into the penis.

ping-pong fracture

A depressed skull fracture in a newborn or very young infant in which the bone bends inward (like a dented ping-pong ball) without breaking. It may occur during strenuous labor and delivery, or in trauma to the pliant skull in the first weeks of life.

Pott fracture

See: Pott, John Percivall

pretrochanteric fracture

A fracture that passes through the greater trochanter of the femur.

Rolando fracture

See: Rolando fracture

simple fracture

A fracture without rupture of ligaments and skin.

fracture of skull

, fractured skull
Loss of the integrity of one or more bones of the cranium. A fracture is classified according to whether it is in the vault or the base but, from the point of view of treatment, a more useful classification is differentiating between a simple fracture (uncommon) and a compound fracture. When a compound fracture occurs in the vault of the skull, the bone is depressed and driven inward, possibly damaging the brain. Treatment is operative. See: fracture

sleeve fracture

An avulsion fracture of the patella that typically occurs as a result of a sudden strong contraction of the quadriceps muscle group.

Smith fracture

See: Smith fracture

snowboarder's fracture

A fracture of the lateral border of the talus caused by inversion and rotation of the talus within the mortise. Signs and symptoms often mimic those of an inversion (lateral) ankle sprain.

fracture of the spine

Fracture of a vertebral body or its bony prominences. Synonym: vertebral fracture See: burst fracture; compression fracture; hangman's fracture; Jefferson fracture

Treatment

The patient is carefully assessed for evidence of neuromuscular compromise and other internal injuries. To prevent complications and promote healing, vests, casts, or halo devices may be used, depending on the location of the fracture. A program of supervised physical therapy may be needed during recovery.

Prognosis

Prognosis depends on the type of spinal fracture and associated spinal cord involvement.

spiral fracture

A fracture that follows a helical line along and around the course of a long bone.

sprain fracture

The separation of a ligament from its insertion, taking with it a piece of the bone.
See: avulsion fracture

stellate fracture

A fracture with numerous fissures radiating from the central point of injury.

straddle fracture

A traumatic fracture of all four pubic rami, often associated with injury to the urethra.

stress fracture

A microfracture that appears without evidence of a single traumatic onset. This type of fracture is difficult to diagnose by standard radiography and may not become visible until 3 to 4 weeks after the onset of symptoms. Scintigraphy, CT, and/or MRI may lead to earlier identification of the fracture lines. Stress fractures occur from repetitive microtraumas (from running, aerobic dancing, or marching or other cyclical actions), from improper shoes on hard surfaces, or from inadequate healing time after stress. Stress fractures are classified as fatigue fractures or insufficiency fractures based on their etiology. Undiagnosed and untreated stress fractures may progress to frank fractures. Synonym: fatigue fracture See: insufficiency fracture

T fracture

Wagstaffe fracture

See: Wagstaffe fractureillustration

fracture

A break, usually of a bone. This occurs when excessive force is applied to a healthy bone or when lesser force is applied to a bone generally weakened by a disease such as OSTEOPOROSIS, or locally weakened by a tumour or cyst. Such a fracture is called a pathological fracture. Fractures may be transverse, oblique or spiral, or the bone may be shattered into pieces (comminuted). Young bone, subjected to bending stress, often fractures on one side but bends on the other. This is called a ‘greenstick’ fracture. In simple fractures the overlying soft tissue is intact. In compound fractures, the fractured bone is exposed and infected. In complicated fractures there is also injury to other nearby structures such as major blood vessels and nerves. Fracture-dislocations pass across a joint and the normal relationship of the joint surfaces to one another is altered.

Fracture

A break or crack in a bone.

fracture

breach in continuity of a bone as a result of injury. Known as a closed fracture when there is no break in the skin or open (compound) when there is a wound linking the broken bone to the outside of the body; comminuted when a bone is broken into several pieces, splintered or crushed; complicated when there is injury to surrounding organs and structures; depressed when the broken bone presses on an underlying structure, e.g. brain or lung; impacted when one part of the broken bone is driven into the other; incomplete when the bone is only cracked or fissured, called a greenstick fracture in children. A pathological fracture can occur in abnormal bone (e.g. with a cancerous deposit) as a result of force which would not break a normal bone; also known as a spontaneous fracture when there is no appreciable violence.

fracture

breakage of bone or cartilage; all fractures are treated by the same principles of rest and immobilization (e.g. internal fixation and/or casting) and pain control (e.g. non-steroidal anti-inflammatory drugs) Table 1
  • avulsion fracture due to joint capsule, ligament or muscle pulling away from bone, e.g. as in sprain, dislocation or excess muscle contraction; pathological traction of involved soft tissues causes separation of a small area (flake or fleck) of cortical bone

  • closed fracture bone ends do not penetrate through overlying soft tissues or skin

  • Colles fracture fracture and dorsal displacement of distal radius

  • comminuted fracture bone is broken into more than two pieces

  • compound fracture open fracture

  • fatigue fracture march fracture

  • flake fracture avulsion fracture

  • fleck fracture avulsion fracture

  • greenstick fracture bending rather than bone breakage, with minimal fracture on outer curve of the bone; typical of a young bone

  • hairline fracture a very fine fracture line, without fragment separation

  • longitudinal fracture line of fracture is parallel to long axis of bone

  • march fracture; stress fracture fracture due to repeated low-grade trauma, classically affecting shaft of second, third or fourth metatarsal; usually begins as a hairline fracture from medial aspect of bone shaft, at a point one-third from head and two-thirds from base of affected metatarsal; tendency to stress fracture is exacerbated by existing bone pathology (e.g. Paget's disease) and/or osteopenia/osteoporosis (i.e. osteopenia of disuse, menopausal osteoporosis, Charcot neuropathy), unaccustomed or strenuous exercise, or subsequent to revascularization of an ischaemic limb (see stress; stress fracture hypothesis; stress fracture symptoms)

  • neuropathic fracture feature of foot with profound sensory neuropathy and loss of pain response; autonomic dysfunction causes opening of arteriovenous anastomoses (shunts) leading to osteopenia, and imbalance of osteoblast/osteoclast function; presents as a hairline, march/stress fracture; contributes to Charcot joint formation

  • open fracture bone ends perforate through overlying tissues and skin, creating an open wound, and almost certain subsequent osteomyelitis

  • osteoporotic fracture fracture of osteoporotic or osteopenic bone

  • simple fracture closed fracture without bone displacement

  • spiral fracture fracture line follows a spiral track across bone shaft; caused by longitudinal twist to bone

  • stress fracture see march fracture

  • transverse fracture fracture line is at right angles to longitudinal bone axis

Table 1: Categorization of bone fractures
Fracture typeDescription
SimpleThe affected bone is broken into two (or occasionally more) segments by transverse breaks, e.g. metatarsal fracture
SpiralThe fracture line follows a spiral across the bone shaft, e.g. of the distal fibula, in association with a severe inversion injury of the ankle
ComminutedThe affected bone is broken into several/many irregular segments, e.g. the calcaneum after a fall from a height
ImpactedThe bone at the fracture site is compressed together by the jamming force of the impact, e.g. the neck of the fibula after a fall from a height
Open/compoundThe bone at the fracture site is so displaced as to penetrate through the overlying soft tissue and skin, so that the end of the bone is exposed
ComplicatedDeep soft tissues/nerves/blood vessels are traumatized by the sharp end of the fractured bone
AvulsionThe traumatic force causes local soft-tissue structures (muscle origins, tendon insertions, ligaments, joint capsule) to pull off a section of the cortex to which they are attached, e.g. avulsion fracture of the tuberosity of the fifth metatarsal
Stress/overuseThe repeated application of low-level trauma causes eventual fracture of cortical bone, e.g. march fracture of the metatarsal (stress fractures may also affect the sesamoids, styloid process of the fifth metatarsal, calcaneum or tibia)
PathologicalThe bone fractures due to an underlying pathology, e.g. Ewing's sarcoma, Paget's disease or von Recklinghausen's disease affecting the tibia
GreenstickIncomplete fracture through the affected bone; commonly affecting children

fracture

1. the breaking of a part, especially a bone.
2. a break in the continuity of bone. Fractures may be caused by trauma, by twisting due to muscle spasm, or indirect loss of leverage or by disease that results in decalcification of the bone.

capillary fracture
one that appears on a radiograph as a fine, hairlike line, the segments of bone not being separated; sometimes seen in fractures of the skull.
closed fracture
one that does not produce an open wound.
comminuted fracture
one in which the bone is splintered or crushed.
complete fracture
one involving the entire cross-section of the bone.
compound fracture
see open fracture (below).

open fracture
one in which a wound through the adjacent or overlying soft tissues communicates with the site of the break; called also compound fracture. A classification system has been used which is based on the mechanism of injury and the extent of tissue damage. In type I, a bone fragment was briefly forced through the skin leaving a communicating wound; type II fractures are caused by impact and there is damage to overlying tissues and exposure of the bone; in type III, there is extensive damage and loss of overlying tissues, including shearing and degloving wounds, with loss of vascular supply.

transverse fracture
one at right angles to the axis of the bone.
trophic fracture
one due to a nutritional (trophic) disturbance.

Patient discussion about fracture

Q. what exactly is a tooth fracture?A broken tooth? there is a tremendous amount of pain with this tooth.

A. I had a temp that stayed on for a month because I couldn't mek it back to the dentist for a awhile. I used to have a Obsession with Jaw Breaker candy but with 2 crowns learned my lesson.

Q. Has anyone fractured their pelvic bone?...and if so how long did it take until you could walk on side injured

A. my cousin fractured his pelvic bone in two places while skiing last winter (my brother pictured the helicopter coming for the rescue, a very good picture..). it took him a month until he could start walking with a cane, and about 2 months later he could walk properly.
if you want i'll send you the picture, you can say it's you :)

Q. I had sugery on a fractured heel what is the recovery process? Wanting to meet people who are going thru this now or have already recovered from this injury. What should I expect?

A. Hey doyen_98, I was wondering how the recovery was coming along. How long ago have you had the surgery?

Hydraulic fracturing or hydraulic fracking is a technique of well stimulation in which a fluid at a high pressure (typically water mixed with sand and chemicals) is injected into an oil well to create minor fractures in the deep rock foundations to allow natural gas, petroleum, and brine to move toward the well from deep reserves.
As companies pursue unconventional sources, horizontal drilling and formation fracturing will become commonplace.
Geotec's gas fracturing technology has been demonstrated in the USA and reported in several publications.
Hydraulic fracturing fluids are used to initiate and/or expand fractures, as well as to transport proppant into fractures in coalbed formations.
Preliminary results show that patient-reported loss in quality-adjusted life years (QALYs) at one year after fracturing was 0.
