Complete immobilization of the head and neck should be done as early as possible and before moving the patient. Immobilization should remain in place until movement of the head and neck is proven safe. "In the presence of severe head trauma, cervical fracture must be presumed until ruled out." Immobilization is imperative to minimize or prevent further spinal cord injury. The only exceptions are when there is imminent danger from an external cause, such as becoming trapped in a burning building.
Non-steroidal anti-inflammatory medications (NSAIDs), such as aspirin or ibuprofen, are contraindicated because they interfere with bone healing. Tylenol (acetaminophen) is a better option. Patients with cervical fractures will likely be prescribed medication for pain control.
In the long term, physical therapy will be given to build strength in the muscles of the neck to increase stability and better protect the cervical spine.
Collars, traction and surgery can be used to immobilize and stabilize the neck after a cervical fracture.
The use of surgery to treat a Jefferson fracture is somewhat controversial. Non-surgical treatment varies depending on if the fracture is stable or unstable, defined by an intact or broken transverse ligament and degree of fracture of the anterior arch. An intact ligament requires the use of a soft or hard collar, while a ruptured ligament may require traction, a halo or surgery. The use of rigid halos can lead to intracranial infections and are often uncomfortable for individuals wearing them, and may be replaced with a more flexible alternative depending on the stability of the injured bones, but treatment of a stable injury with a halo collar can result in a full recovery. Surgical treatment of a Jefferson fracture involves fusion or fixation of the first three cervical vertebrae; fusion may occur immediately, or later during treatment in cases where non-surgical interventions are unsuccessful. A primary factor in deciding between surgical and non-surgical intervention is the degree of stability as well as the presence of damage to other cervical vertebrae.
Though a serious injury, the long-term consequences of a Jefferson's fracture are uncertain and may not impact longevity or abilities, even if untreated. Conservative treatment with an immobilization device can produce excellent long-term recovery.
Most hip fractures are treated surgically by implanting an orthosis. Surgical treatment outweighs the risks of nonsurgical treatment which requires extensive bedrest. Prolonged immobilization increases risk of thromboembolism, pneumonia, deconditioning, and decubitus ulcers. Regardless, the surgery is a major stress, particularly in the elderly. Pain is also significant, and can also result in immobilization, so patients are encouraged to become mobile as soon as possible, often with the assistance of physical therapy. Skeletal traction pending surgery is not supported by the evidence. Regional nerve blocks are useful for pain management in hip fractures.
Red blood cell transfusion is common for people undergoing hip fracture surgery due to the blood loss sustained during surgery and from the injury. Adverse effects of blood transfusion may occur and are avoided by restrictive use of blood transfusion rather than liberal use. Restrictive blood transfusion is based on symptoms of anemia and thresholds lower than the 10 g/dL haemoglobin used for liberal blood transfusion.
If operative treatment is refused or the risks of surgery are considered to be too high the main emphasis of treatment is on pain relief. Skeletal traction may be considered for long term treatment. Aggressive chest physiotherapy is needed to reduce the risk of pneumonia and skilled rehabilitation and nursing to avoid pressure sores and DVT/pulmonary embolism Most people will be bedbound for several months. Non-operative treatment is now limited to only the most medically unstable or demented patients, or those who are nonambulatory at baseline with minimal pain during transfers.
Rigid braces that support the head and chest are also prescribed. Examples include the
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.
Rehabilitation has been proven to increase daily functional status. It is unclear if the use of anabolic steroids effects recovery.
Minor nasal fractures may be allowed to heal on their own provided there is not significant cosmetic deformity. Ice and pain medication may be prescribed to ease discomfort during the healing process. For nasal fractures where the nose has been deformed, manual alignment may be attempted, usually with good results. Injuries involving other structures (Types 2 and 3) must be recognized and treated surgically.
Bone stimulation may be with either electromagnetic or ultrasound waves. Ultrasound stimulation has tentative evidence of supporting better healing in long bones that have not healed after three months. Evidence; from a Cochrane review however, does not show that ultrasound decreases rates of nonunion. Another review has, however, suggested it as an alternative to surgery.
Surgical treatment options include:
- Removal of all scar tissue from between the fracture fragments
- Immobilization of the fracture with internal or external fixation. Metal plates, pins, screws, and rods, that are screwed or driven into a bone, are used to stabilize the broken bone fragments.
- Bone grafting. Donor bone or autologous bone (harvested from the same person undergoing the surgery) is used as a stimulus to bone healing. The presence of the bone is thought to cause stem cells in the circulation and marrow to form cartilage, which then turns to bone, instead of a fibrous scar that forms to heal all other tissues of the body. Bone is the only tissue that can heal without a fibrous scar. Autologus bone graft is the "gold standard" treatment of the non union the bone is obtained from the iliac crest.
In simple cases healing may be evident within 3 months. Gavriil Ilizarov revolutionized the treatment of recalcitrant nonunions demonstrating that the affected area of the bone could be removed, the fresh ends "docked" and the remaining bone lengthened using an external fixator device. The time course of healing after such treatment is longer than normal bone healing. Usually there are signs of union within 3 months, but the treatment may continue for many months beyond that.
An immediate need in treatment is to ensure that the airway is open and not threatened (for example by tissues or foreign objects), because airway compromisation can occur rapidly and insidiously, and is potentially deadly. Material in the mouth that threatens the airway can be removed manually or using a suction tool for that purpose, and supplemental oxygen can be provided. Facial fractures that threaten to interfere with the airway can be reduced by moving the bones back into place; this both reduces bleeding and moves the bone out of the way of the airway. Tracheal intubation (inserting a tube into the airway to assist breathing) may be difficult or impossible due to swelling. Nasal intubation, inserting an endotracheal tube through the nose, may be contraindicated in the presence of facial trauma because if there is an undiscovered fracture at the base of the skull, the tube could be forced through it and into the brain. If facial injuries prevent oraotracheal or nasotracheal intubation, a surgical airway can be placed to provide an adequate airway. Although cricothyrotomy and tracheostomy can secure an airway when other methods fail, they are used only as a last resort because of potential complications and the difficulty of the procedures.
A dressing can be placed over wounds to keep them clean and to facilitate healing, and antibiotics may be used in cases where infection is likely. People with contaminated wounds who have not been immunized against tetanus within five years may be given a tetanus vaccination. Lacerations may require stitches to stop bleeding and facilitate wound healing with as little scarring as possible. Although it is not common for bleeding from the maxillofacial region to be profuse enough to be life-threatening, it is still necessary to control such bleeding. Severe bleeding occurs as the result of facial trauma in 1–11% of patients, and the origin of this bleeding can be difficult to locate. Nasal packing can be used to control nose bleeds and hematomas that may form on the septum between the nostrils. Such hematomas need to be drained. Mild nasal fractures need nothing more than ice and pain killers, while breaks with severe deformities or associated lacerations may need further treatment, such as moving the bones back into alignment and antibiotic treatment.
Treatment aims to repair the face's natural bony architecture and to leave as little apparent trace of the injury as possible. Fractures may be repaired with metal plates and screws. They may also be wired into place. Bone grafting is another option to repair the bone's architecture, to fill out missing sections, and to provide structural support. Medical literature suggests that early repair of facial injuries, within hours or days, results in better outcomes for function and appearance.
Surgical specialists who commonly treat specific aspects of facial trauma are oral and maxillofacial surgeons. These surgeons are trained in the comprehensive management of trauma to the lower, middle and upper face and have to take written and oral board examinations covering the management of facial injuries.
Management depends on the severity of the fracture. An undisplaced fracture may be treated with a cast alone. The cast is applied with the distal fragment in palmar flexion and ulnar deviation. A fracture with mild angulation and displacement may require closed reduction. There is some evidence that immobilization with the wrist in dorsiflexion as opposed to palmarflexion results in less redisplacement and better functional status. Significant angulation and deformity may require an open reduction and internal fixation or external fixation. The volar forearm splint is best for temporary immobilization of forearm, wrist and hand fractures, including Colles fracture.
There are several established instability criteria:
dorsal tilt >20°,
comminuted fracture,
abruption of the ulnar styloid process,
intraarticular displacement >1mm,
loss of radial height >2mm.
A higher amount of instability criteria increases the likelihood of operative treatment.
Treatment modalities differ in the elderly.
Repeat Xrays are recommended at one, two, and six weeks to verify proper healing.
X-rays of the chest are taken in people with chest trauma and symptoms of sternal fractures, and these may be followed by CT scanning. Since X-rays taken from the front may miss the injury, they are taken from the side as well.
Management involves treating associated injuries; people with sternal fractures but no other injuries do not need to be hospitalized. However, because it is common for cardiac injuries to accompany sternal fracture, heart function is monitored with electrocardiogram. Fractures that are very painful or extremely out of place can be operated on to fix the bone fragments into place, but in most cases treatment consists mainly of reducing pain and limiting movement. The fracture may interfere with breathing, requiring tracheal intubation and mechanical ventilation.
Patients who have experienced a pathologic fracture will be investigated for the cause of the underlying disease, if it is unknown. Treatment of any underlying disease, such as chemotherapy if indicated for bone cancer, may help to improve the pain of a sternal fracture.
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.
A 2013 Cochrane review assessed clinical studies on surgical (open reduction) and non-surgical (closed reduction) management of mandible fractures that do not involve the condyle. The review found insufficient evidence to recommend the effectiveness of any single intervention.
The best treatment for condylar fractures is controversial. There are two main options, namely closed reduction or open reduction and fixation. Closed reduction may involve intermaxillary fixation, where the jaws are splinted together in the correct position for a period of weeks. Open reduction involves surgical exposure of the fracture site, which can be carried out via incisions within the mouth or incisions outside the mouth over the area of the condyle. Open reduction is sometimes combined with use of an endoscope to aid visualization of fracture site. Although closed reduction carries a risk of the bone healing out of position, with consequent alteration of the bite or the creation of facial asymmetry, it does not risk temporary damage to the facial nerve or result in any facial scar that accompanies open reduction. A systematic review was unable to find sufficient evidence of the superiority of one method over another in the management of condylar fractures. Paediatric condylar fractures are especially problematic, owing to the remaining growth potential and possibility of ankylosis of the joint. Early mobilization is often recommended as in the Walker protocol.
Measures to reduce facial trauma include laws enforcing seat belt use and public education to increase awareness about the importance of seat belts and motorcycle helmets. Efforts to reduce drunk driving are other preventative measures; changes to laws and their enforcement have been proposed, as well as changes to societal attitudes toward the activity. Information obtained from biomechanics studies can be used to design automobiles with a view toward preventing facial injuries. While seat belts reduce the number and severity of facial injuries that occur in crashes, airbags alone are not very effective at preventing the injuries. In sports, safety devices including helmets have been found to reduce the risk of severe facial injury. Additional attachments such as face guards may be added to sports helmets to prevent orofacial injury (injury to the mouth or face); mouth guards also used.
Bone stability after a fracture occurs between 3 and 4 weeks. Some experts suggest not wearing glasses or blowing the nose during this time as it can affect the bone alignment. Full bone fusion occurs between 4 and 8 weeks. General activity is fine after 1–2 weeks, but contact sports are not advisable for at least 2–3 months, depending on the extent of injury. It is recommended that when participating in sports a face guard should be worn for at least 6 weeks post-injury.
Treatment of condylar resorption is controversial. Orthognathic surgery may be done to reconstruct and stabilize the condyles and disc of the temporomandibular joint. Anti-infammatory medication is also used to slow the resorption process. Orthodontics may be used to treat the occlusion. Arthrocentesis, and arthroscopic surgery are also sometimes used to treat disc displacement and other symptoms.
It is sometimes possible to correct the problem with surgery, though this has high failure rates for treatment of post-traumatic radioulnar synostosis.
Evidence does not support the use of preventative antibiotics regardless of the presence of a cerebral spinal fluid leak.
Most head injuries are of a benign nature and require no treatment beyond analgesics and close monitoring for potential complications such as intracranial bleeding. If the brain has been severely damaged by trauma, neurosurgical evaluation may be useful. Treatments may involve controlling elevated intracranial pressure. This can include sedation, paralytics, cerebrospinal fluid diversion. Second line alternatives include decompressive craniectomy (Jagannathan et al. found a net 65% favorable outcomes rate in pediatric patients), barbiturate coma, hypertonic saline and hypothermia. Although all of these methods have potential benefits, there has been no randomized study that has shown unequivocal benefit.
Clinicians will often consult clinical decision support rules such as the Canadian CT Head Rule or the New Orleans/Charity Head injury/Trauma Rule to decide if the patient needs further imaging studies or observation only. Rules like these are usually studied in depth by multiple research groups with large patient cohorts to ensure accuracy given the risk of adverse events in this area.
A sternal fracture is a fracture of the sternum (the breastbone), located in the center of the chest. The injury, which occurs in 5–8% of people who experience significant blunt chest trauma, may occur in vehicle accidents, when the still-moving chest strikes a steering wheel or dashboard or is injured by a seatbelt. Cardiopulmonary resuscitation, commonly known as CPR, has also been known to cause thoracic injury, including sternum and rib fractures. Sternal fractures may also occur as a pathological fracture, in people who have weakened bone in their sternum, due to another disease process. Sternal fracture can interfere with breathing by making it more painful; however, its primary significance is that it can indicate the presence of serious associated internal injuries, especially to the heart and lungs.
A Jefferson fracture is a bone fracture of the anterior and posterior arches of the C1 vertebra, though it may also appear as a three- or two-part fracture. The fracture may result from an axial load on the back of the head or hyperextension of the neck (e.g. caused by diving), causing a posterior break, and may be accompanied by a break in other parts of the cervical spine.
It is named after the British neurologist and neurosurgeon Sir Geoffrey Jefferson, who reported four cases of the fracture in 1920 in addition to reviewing cases that had been reported previously.
An ulna fracture is a break of the ulna bone in the forearm. They are often associated with radius fractures. When the middle portion of the ulna is broken without other associated fractures, it may be called a nightstick fracture.
A nightstick fracture is classically caused by being hit on the inside of the forearm.
Treatment of nightstick fractures may be with splinting and early movement.
Treatment of the flail chest initially follows the principles of advanced trauma life support. Further treatment includes:
- Good pain management includes intercostal blocks and avoiding opioid pain medication as much as possible. This allows much better ventilation, with improved tidal volume, and increased blood oxygenation.
- Positive pressure ventilation, meticulously adjusting the ventilator settings to avoid pulmonary barotrauma.
- Chest tubes as required.
- Adjustment of position to make the person most comfortable and provide relief of pain.
- Aggressive pulmonary toilet
Surgical fixation can help in significantly reducing the duration of ventilatory support and in conserving the pulmonary function.
A person may be intubated with a double lumen tracheal tube. In a double lumen endotracheal tube, each lumen may be connected to a different ventilator. Usually one side of the chest is affected more than the other, so each lung may require drastically different pressures and flows to adequately ventilate.
