A diagnosis can be made using clinical examination, laryngoscope examination, and/or radiographic studies.
A bone fracture may be diagnosed based on the history given and the physical examination performed. Radiographic imaging often is performed to confirm the diagnosis. Under certain circumstances, radiographic examination of the nearby joints is indicated in order to exclude dislocations and fracture-dislocations. In situations where projectional radiography alone is insufficient, Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) may be indicated.
An X-ray is essential for the proper diagnosis of a malunion. The doctor will look into the patient’s history and the treatment process for the bone fracture. Oftentimes a CT scan and probably a MRI are also used in diagnosis. MRI are used to check of cartilage and ligament issues that developed due to the malunion and misalignment. CT scans are used to locate normal or abnormal structures within the body and to help during procedures to guide the placement of instruments and/or treatments.
Evidence does not support the use of preventative antibiotics regardless of the presence of a cerebral spinal fluid leak.
When a child experiences a fracture, he or she will have pain and will not be able to easily move the fractured area. A doctor or emergency care should be contacted immediately. In some cases even though the child will not have pain and will still be able to move, medical help must be sought out immediately. To decrease the pain, bleeding, and movement a physician will put a splint on the fractured area. Treatment for a fracture follows a simple rule: the bones have to be aligned correctly and prevented from moving out of place until the bones are healed. The specific treatment applied depends on how severe the fracture is, if it’s an open or closed fracture, and the specific bone involved in the fracture (a hip fracture is treated differently from a forearm fracture for example)
Different treatments for different fractures:
The general treatments for common fractures are as follows:
A compound elevated skull fracture is a rare type of skull fracture where the fractured bone is elevated above the intact outer table of the skull. This type of skull fracture is always compound in nature. It can be caused during an assault with a weapon where the initial blow penetrates the skull and the underlying meninges and, on withdrawal, the weapon lifts the fractured portion of the skull outward. It can also be caused the skull rotating while being struck in a case of blunt force trauma, the skull rotating while striking an inanimate object as in a fall, or it may occur during transfer of a patient after an initial compound head injury.
A fracture in conjunction with an overlying laceration that tears the epidermis and the meninges—or runs through the paranasal sinuses and the middle ear structures, putting the outside environment in contact with the cranial cavity—is a compound fracture.
Compound fractures may either be clean or contaminated. Intracranial air (pneumocephalus) may occur in compound skull fractures.
The most serious complication of compound skull fractures is infection. Increased risk factors for infection include visible contamination, meningeal tear, loose bone fragments and presenting for treatment more than eight hours after initial injury.
Non-displaced fractures usually heal without intervention. Patients with basilar skull fractures are especially likely to get meningitis. Unfortunately, the efficacy of prophylactic antibiotics in these cases is uncertain.
Children in general are at greater risk because of their high activity levels. Children that have risk-prone behaviors are at even greater risk.
Most fractures of the scapula can be seen on a chest X-ray; however, they may be missed during examination of the film. Serious associated injuries may distract from the scapular injury, and diagnosis is often delayed. Computed tomography may also be used. Scapular fractures can be detected in the standard chest and shoulder radiographs that are given to patients who have suffered significant physical trauma, but much of the scapula is hidden by the ribs on standard chest X-rays. Therefore, if scapular injury is suspected, more specific images of the scapular area can be taken.
Computed tomography is the most sensitive and specific of the imaging techniques. The facial bones can be visualized as slices through the skeletal in either the axial, coronal or sagittal planes. Images can be reconstructed into a 3-dimensional view, to give a better sense of the displacement of various fragments. 3D reconstruction, however, can mask smaller fractures owing to volume averaging, scatter artifact and surrounding structures simply blocking the view of underlying areas.
Research has shown that panoramic radiography is similar to computed tomography in its diagnostic accuracy for mandible fractures and both are more accurate than plain film radiograph. The indications to use CT for mandible fracture vary by region, but it does not seem to add to diagnosis or treatment planning except for comminuted or avulsive type fractures, although, there is better clinician agreement on the location and absence of fractures with CT compared to panoramic radiography.
Anteroposterior (AP) and lateral radiographs the include the entire length of the lower leg (knee to ankle) are highly sensitive and specific for tibial shaft fractures.
Two systems of fracture classification are commonly used to aid diagnosis and management of tibia shaft fractures:
- Oestern and Tscherne Classification
- Gustilo-Anderson Classification
Management is dependent on the determination of whether the fracture is open or closed.
Diagnosis is based on symptom and confirmed with X-rays. In children an MRI may be required.
There are various classification systems of mandibular fractures in use.
A Cochrane review of low-intensity pulsed ultrasound to speed healing in newly broken bones found insufficient evidence to justify routine use. Other reviews have found tentative evidence of benefit. It may be an alternative to surgery for established nonunions.
Vitamin D supplements combined with additional calcium marginally reduces the risk of hip fractures and other types of fracture in older adults; however, vitamin D supplementation alone did not reduce the risk of fractures.
Treatment options vary from very conservative to aggressive. Conservative options include rest, observation, pain control, diet changes, use of a nasopharyngeal tube or oropharyngeal tube, and antibiotic therapy. More aggressive options include surgical repair of the hyoid bone and/or tracheotomy. Surgical treatment was used in 10.9% of cases in a 2012 meta-analysis.
Treatment involves pain medication and immobilization at first; later, physical therapy is used. Ice over the affected area may increase comfort. Movement exercises are begun within at least a week of the injury; with these, fractures with little or no displacement heal without problems. Over 90% of scapular fractures are not significantly displaced; therefore, most of these fractures are best managed without surgery. Fractures of the scapular body with displacement may heal with malunion, but even this may not interfere with movement of the affected shoulder. However, displaced fractures in the scapular processes or in the glenoid do interfere with movement in the affected shoulder if they are not realigned properly. Therefore, while most scapular fractures are managed without surgery, surgical reduction is required for fractures in the neck or glenoid; otherwise motion of the shoulder may be impaired.
Radiography, imaging of tissues using X-rays, is used to rule out facial fractures. Angiography (X-rays taken of the inside of blood vessels) can be used to locate the source of bleeding. However the complex bones and tissues of the face can make it difficult to interpret plain radiographs; CT scanning is better for detecting fractures and examining soft tissues, and is often needed to determine whether surgery is necessary, but it is more expensive and difficult to obtain. CT scanning is usually considered to be more definitive and better at detecting facial injuries than X-ray. CT scanning is especially likely to be used in people with multiple injuries who need CT scans to assess for other injuries anyway.
Removable splints result in better outcomes than casting in children with torus fractures of the distal radius.
There is no specific treatment for rib fractures, but various supportive measures can be taken. In simple rib fractures, pain can lead to reduced movement and cough suppression; this can contribute to formation of secondary chest infection. Flail chest is a potentially life-threatening injury and will often require a period of assisted ventilation. Flail chest and first rib fractures are high-energy injuries and should prompt investigation of damage to underlying viscera (e.g., lung contusion) or remotely (e.g., cervical spine injury). Spontaneous fractures in athletes generally require a cessation of the cause, e.g., time off rowing, while maintaining cardiovascular fitness.
Treatment options for internal fixation/repair of rib fractures include:
- Judet and/or sanchez plates/struts are a metal plate with strips that bend around the rib and then is further secured with sutures.
- Synthes matrixrib fixation system has two options: a precontoured metal plate that uses screws to secure the plate to the rib; and/or an intramedullary splint which is tunneled into the rib and secured with a set screw.
- Anterior locking plates are metal plates that have holes for screws throughout the plate. The plate is positioned over the rib and screwed into the bone at the desired position. The plates may be bent to match the contour of the section.
- U-plates can also be used as they clamp on to the superior aspect of the ribs using locking screws.
Once diagnosed and located, surgery is the most common treatment for a malunion. The surgery consists for the surgeon re-breaking the bone and realigning it to the anatomically correct position. There are different types and levels of extremity where it is possible that the bone will trimmed to allow full orientation at the fractured spot. Most often, either screws, plates or pins are used secure the new alignment. It is possible that a bone graft could be used to help with healing.
After surgery make sure not to smoke or use any nicotine products as that affects the healing process by limiting blood flow. Also, don’t use any NSAIDS (non steroidal anti-inflammatory drug) as that will also affect the blood flow and the healing to the area of fracture. Do not put weight on the area where the fracture and surgery occurred until informed by your doctor and that could lead to other and future problems. After surgery and the surgical stitches are removed you will be put into a cast to complete the healing process. During follow ups an X-ray or a CT scan may be used to verify that the fracture is healing properly and is now in the anatomical correct position.
The greenstick fracture pattern occurs as a result of bending forces. Activities with a high risk of falling are risk factors. Non-accidental injury more commonly causes spiral (twisting) fractures but a blow on the forearm or shin could cause a green stick fracture. The fracture usually occurs in children and teens because their bones are flexible, unlike adults whose more brittle bones usually break.
Treatment may be with or without surgery, depending on the type of fracture.
Several indirect measurements on CT can be used to assess ligamentous integrity at the craniocervical junction. The Wackenheim line, a straight line extending along the posterior margin of the clivus through the dens, normally intersects the posterior margin of the tip of the dens on plain film. The basion to axion interval, or BAI, is also used, which is determined by measuring the distance between an imaginary vertical line at the anterior skull base, or basion, at the foramen magnum, and the axis of the cervical spine along its posterior margin, which should measure 12 mm, an assessment more reliable on radiograph than CT. The distance between the atlas and the occipital condyles, the atlanto-occipital interval (AOI), should measure less than 4 mm, and is better assessed on coronal images.
The distances between the dens and surrounding structures are also key features that can suggest the diagnosis, with the normal distance between the dens and basion (BDI) measuring less than 9 mm on CT, and the distance between the dens and atlas (ADI) measuring less than 3 mm on CT, although this can be increased in cases of rheumatoid arthritis due to pannus formation. Lastly, the atlanto-occipital interval can be measured.
The Powers ratio was formerly used, which was the tip of the basion to the spinolaminar line, divided by the distance from the tip of the opisthion to the midpoint of the posterior aspect of the anterior arch of C1. It is no longer recommended due to low sensitivity and difficulty identifying landmarks. It also will miss vertical or posterior displacement of the cervical spine.
