Definition

Bone is the hardest tissue in the human body, but when bones are subjected to forces that exceed their strength, they may break. The likelihood that a bone will break depends on the location of the bone in the body, the thickness of the bone, and the circumstances under which the force was applied. The most commonly broken bones are those in the wrist, hip, and ankle. The terms “break” and “fracture” mean the same thing. Fracture repair is the process of rejoining and realigning the ends of broken bones, usually performed by an orthopedist, general surgeon, or family doctor. In cases of an emergency, first aid measures should be used to provide temporary realignment and immobilization until proper medical help is available.

Purpose

Fracture repair is required when there is a need to restore the normal alignment and function of a broken bone. Throughout the stages of fracture healing, the bones must be held firmly in the correct position. In the event that a fracture is not properly repaired, misalignment of the bone may occur, resulting in possible physical dysfunction of the bone, adjacent joint, or region of the body.

KEY TERMS

Compound fracture— A fracture in which the broken end or ends of the bone have penetrated through the skin; also known as an open fracture.

Staphylococcal infection— An infection caused by any of several pathogenic species of Staphylococcus, commonly characterized by the formation of abscesses in the skin or other organs.

Streptococcal infection— An infection caused by a pathogenic bacterium of one of several species of the genus Streptococcus or their toxins. Almost any organ in the body may be involved.

Demographics

The incidence of fractures that occur in the United States can only be estimated because fractures are not always reported. The average person sustains two to three fractured bones during the course of a lifetime. A reasonable estimate is approximately nine million fractures per year.

Fractures are slightly more common in children and adolescents than in young adults due to the levels and kinds of activities in which they engage. Fractures become more common in adults as they age due to changes in bone structure and generally diminished levels of physical activity.

Description

Fracture repair is accomplished by means of applied traction, surgery, and immobilizing affected bones. The bone fragments are aligned as closely as possible to their normal position without injuring the skin. Metal wires or screws may be needed to align smaller bone fragments. Once the broken ends of the bone are set, the affected area is immobilized for several weeks and kept rigid with a sling, plaster cast, brace, or splint. With the use of traction, muscles pulling on the fracture site are neutralized by weights attached to a series of ropes running over pulleys. Strategically implanted electrical stimulation devices have proven beneficial in healing a fracture site, especially when the fracture is healing poorly and repair by other means is difficult.

Diagnosis/Preparation

Fractures are commonly diagnosed on the basis of history of trauma or the presence of pain. An x ray is usually taken to confirm the diagnosis.

Precautions for fracture repair include any relevant factors in an individual’s medical condition and history. These include allergic reactions to anesthesia and the presence of bleeding disorders that may complicate surgery.

Preparation often begins with emergency splinting to immobilize the body part or parts involved. When fracture repair is necessary, the procedure is often performed in a hospital, but can also be successfully done in an outpatient surgical facility, doctor’s office, or emergency room. Before any surgery for fracture repair, blood and urine studies may be performed. X rays may be obtained. It must be noted, however, that not all fractures are immediately apparent on an initial x-ray examination. In such a case, when a fracture is highly suspected, the extent of the fracture can be properly diagnosed by repeating the x rays 10-14 days later. Depending upon the situation, local or general anesthesia may be used during fracture repair.

Aftercare

Immediately following surgical repair of a fracture, x rays may be again taken through the cast or splint to evaluate whether the rejoined pieces are in a good position for healing. The x ray can be performed either before the application of the splint or at least before an individual is awakened from the general anesthesia. Persons need to exercise caution and not place excess pressure on any part of the cast until it is completely dry. Excess pressure on the operative site should also be avoided until complete healing has taken place and the injury has been re-examined by the physician or surgeon. If the cast becomes exposed to moisture, it may soften and require repair. For this reason, plastic has largely replaced plaster as the casting material of choice. The injured region should be elevated or propped up whenever possible to reduce the possibility of swelling.

Risks

Surgical risks of fracture repair are greater in persons over 60 years of age because the bones often require more time to properly heal. Obesity may place extra stress on the fracture site, affecting healing and possibly increasing the risk of re-fracturing the same bone. The healing process after fracture repair may also be slowed by smoking, poor nutrition, alcoholism, and chronic illness. Some medications may affect the fracture site, causing poor union; such medications include anti-hypertensives and steroids such as cortisone.

WHO PERFORMS THE PROCEDURE AND WHERE IS IT PERFORMED?

Fracture repair is usually performed by an orthopedic surgeon, general surgeon, or family physician. In cases of an emergency, first aid measures should be used for temporary realignment and immobilization until proper medical help can be obtained. Relatively uncomplicated fractures may be immobilized in a physician’s office. More commonly, fractures are treated in a hospital setting.

Possible complications following fracture repair include excessive bleeding, improper fit of joined bone ends, pressure on nearby nerves, delayed healing, and a permanent incomplete healing (union) of the fracture. If there is a poor blood supply to the fractured site and one of the portions of broken bone is not adequately supplied with blood, the bony portion may die and healing of the fracture will not take place. This complication is called aseptic necrosis. Poor immobilization of the fracture from improper casting that permits motion between the bone parts may prevent healing and repair of the bone, and result in possible deformity. Infection can interfere with bone repair. This risk is greater in the case of a compound fracture (a bone fracture involving a portion of bone that breaks through the surface of skin). Compound fracture sites provide ideal conditions for severe infections by Streptococcus and Staphylococcus bacteria. Occasionally, fractured bones in the elderly may never heal properly. The risk is increased when nutrition is poor.

Normal results

Once the procedure for fracture repair is completed, the body begins to produce new tissue to bridge the fracture site and rejoin the broken pieces. At first, this tissue (called a callus) is soft and easily injured. Later, the body deposits bone minerals (primarily compounds containing calcium) until the callus becomes a solid piece of bone. The fracture site is thus further strengthened with extra bone. It usually takes about six weeks for the pieces of a broken bone to knit (heal) together. The exact time required for healing depends on the type of fracture and the extent of damage. Before the use of x rays, fracture repair was not always accurate and frequently resulted in crippling deformities. With modern x-ray technology, physicians can view the extent of the fracture, check the setting following the repair, and be certain after the

QUESTIONS TO ASK THE DOCTOR

Candidates for fracture repair should consider asking the following questions:

  • What type of fracture do I have?
  • Is the surgeon properly trained in the proposed method of fracture repair?
  • How many similar procedures has the surgeon performed?

procedure that the bones have not moved from their intended alignment. Children’s bones usually heal more rapidly than do the bones of adults.

Morbidity and mortality rates

Morbidity associated with fracture repair includes damage to nerves or primary blood vessels that are adjacent to the fracture site. Improper alignment causing deformity is an abnormal outcome that is relatively rare due to presently available medical technology.

Mortality associated with fractures is also rare. It is usually associated with infections or contamination acquired during the fracture process.

Alternatives

There are no alternatives to proper fracture repair. Problems associated with allowing a fracture to heal without intervention include misalignment, deformity, loss of function, and pain.

Magnetic fields are occasionally used to stimulate healing when conventional techniques are not effective.

Fracture Repair

Definition

Fracture repair is the process of rejoining and realigning the ends of broken bones. This procedure is usually performed by an orthopedist, general surgeon, or family doctor. In cases of an emergency, first aid measures should be evoked for temporary realignment and immobilization until proper medical help is available.

Purpose

Fracture repair is required when there is a need for restoration of the normal position and function of the broken bone. Throughout the stages of fracture healing, the bones must be held firmly in the correct position. In the event the fracture is not properly repaired, malalignment of the bone may occur, resulting in possible physical dysfunction of the bone or joint of that region of the body.

Precautions

Precautions for fracture repair are anything found to be significant with patients' medical diagnosis and history. This would include an individual's tolerance to anesthesia and the presence of bleeding disorders that may be present to complicate surgery.

Description

Fracture repair is applied by means of traction, surgery, and/or by immobilization of the bones. The bone fragments are aligned as close as possible to the normal position without injuring the skin. Metal wires or screws may be needed to align smaller bone fragments. Once the broken ends of the bone are set, the affected area is immobilized for several weeks and kept rigid with a sling, plaster cast, brace or splint. With the use of traction, muscle pull on the fracture site is overcome by weights attached to a series of ropes running over pulleys. Strategically implanted electrical stimulation devices have proven beneficial in healing a fracture site, especially when the fracture is healing poorly and repair by other means is difficult.

Preparation

Emergency splinting may be required to immobilize the body part or parts involved. When fracture repair is necessary, the procedure is often performed in a hospital but can also be successfully done in an out-patient surgical facility, doctor's office or emergency room. Before any surgery for fracture repair, blood and urine studies may be taken from the patient. X rays may follow this if not previously acquired. It has been noted however, that not all fractures are immediately apparent on an initial x-ray examination. In this case, where a fracture is definitely suspected the extent of the fracture can be properly diagnosed by repeating the x rays 10-14 days later. Depending upon the situation, local or general anesthesia may be used for fracture repair.

Aftercare

After surgery, x rays may be again taken through the cast or splint to evaluate if rejoined pieces remain in good position for healing. This is usually performed either before the application of the splint or at least before the patient is awakened from the general anesthesia. The patient needs to be cautious not to place excess pressure on any part of the cast until it is completely dry. The patient also should avoid excess pressure on the operative site until complete healing has taken place and the injury has been re-examined by the physician. If the cast becomes exposed to moisture it may soften and require repair. The patient should also be instructed to keep the injured region propped up whenever possible to reduce the possibility of swelling.

Risks

Surgical risks of fracture repair are greater in patients over 60 years of age because the bones often taking longer to heal properly. Obesity may place extra stress on the healing site, affecting healing and possibly risking reinjury. Smoking may slow the healing process after fracture repair, as well as poor nutrition, alcoholism, and chronic illness. Some medications may affect the fracture site, causing poor union. Such medications include anti-hypertensives and cortisone.

Possible complications following fracture repair include excessive bleeding, improper fit of joined bone ends, pressure on nearby nerves, delayed healing, and a permanent incomplete healing of the fracture. If there is a poor blood supply to the fractured site with one of the portions of broken bone not properly supplied by the blood, the bony portion will die and healing of the fracture will not take place. This is called aseptic necrosis. Poor immobilization of the fracture from improper casting which permits motion between the bone parts may prevent healing and repair of the bone with possible deformity. Infection can interfere with bone repair. This risk is greater in the case of a compound fracture (a bone fracture causing an open wound) where ideal conditions are present for severe streptococcal and staphylococcal infections. Occasionally, fractured bones in the elderly may possibly never heal properly. The risk is increased when nutrition is poor.

Normal results

Once the procedure for fracture repair is completed, the body begins to produce new tissue to bridge the broken pieces. At first, this tissue (called a callus) is soft and easily injured. Later, the body deposits bone minerals until the callus becomes a solid piece of bone. The fracture site is thus strengthened further with extra bone. It usually takes about six weeks for a broken bone to heal together. The exact time required for healing depends on the type of fracture and the extent of damage. Before the use of x rays, fracture repair was not always accurate, resulting in crippling deformities. With modern x-ray technology, the physician can view the extent of the fracture, check the setting following the repair, and be certain after the procedure that the bones have not moved from their intended alignment. Children's bones usually heal relatively rapidly.

Abnormal results

Abnormal results of fracture repair include damage to nearby nerves or primary blood vessels. Improper alignment causing deformity is also an abnormal outcome, however, with today's medical technology it is relatively rare.
