Cervical fracture
A cervical fracture, commonly called a broken neck, is a fracture of any of the seven cervical vertebrae in the neck. Examples of common causes in humans are traffic collisions and diving into shallow water. Abnormal movement of neck bones or pieces of bone can cause a spinal cord injury, resulting in loss of sensation, paralysis, or usually death soon thereafter (~1 min.), primarily via compromising neurological supply to the respiratory muscles as well as innervation to the heart.
Causes
Considerable force is needed to cause a cervical fracture. Vehicle collisions and falls are common causes. A severe, sudden twist to the neck or a severe blow to the head or neck area can cause a cervical fracture.
Although high energy trauma is often associated with cervical fractures in the younger population, low energy trauma is more common in the geriatric population. In a study from Norway the most common cause was falls and the relative incidence of CS-fx increased significantly with age.[1]
Sports that involve violent physical contact carry a risk of cervical fracture, including American football, association football (especially the goalkeeper), ice hockey, rugby, and wrestling. Spearing an opponent in football or rugby, for instance, can cause a broken neck. Cervical fractures may also be seen in some non-contact sports, such as gymnastics, skiing, diving, surfing, powerlifting, equestrianism, mountain biking, and motor racing.
Certain penetrating neck injuries can also cause cervical fracture which can also cause internal bleeding among other complications.
Execution by hanging is intended to cause a fatal cervical fracture. The knot in the noose is placed to the left of the condemned, so that at the end of the drop, the head is jolted sharply upwards and to the right. The force breaks the neck, causing an immediate loss of consciousness and death within a few minutes.

Treatment
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.
NSAIDs (Non-steroidal anti-inflammatory drugs), such as Aspirin or Ibuprofen, are contraindicated because they interfere with bone healing. Paracetamol 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.
Cervical collars, traction and surgery can be used to immobilize and stabilize the neck after a cervical fracture.
Cervical collar
Minor fractures can be immobilized with a cervical collar without need for traction or surgery. A soft collar is fairly flexible and is the least limiting but can carry a high risk of further neck damage in patients with osteoporosis. It can be used for minor injuries or after healing has allowed the neck to become more stable.
A range of manufactured rigid collars are also used, usually comprising a firm plastic bi-valved shell secured with Velcro straps and removable padded liners. The most frequently prescribed are the Aspen, Malibu, Miami J, and Philadelphia collars. All these can be used with additional chest and head extension pieces to increase stability.
Rigid braces
Rigid braces that support the head and chest are also prescribed.[2] Examples include the Sterno-Occipital Mandibular Immobilization Device (SOMI), Lerman Minerva and Yale types. Special patients, such as very young children or non-cooperative adults, are sometimes still immobilized in medical plaster of paris casts, such as the Minerva cast.
Traction
Traction can be applied by free weights on a pulley or a halo type brace. The halo brace is the most rigid cervical brace, used when limiting motion to the minimum that is essential, especially with unstable cervical fractures. It can provide stability and support during the time (typically 8–12 weeks) needed for the cervical bones to heal.
Surgery
Surgery may be needed to stabilize the neck and relieve pressure on the spinal cord. A variety of surgeries are available depending on the injury. Surgery to remove a damaged intervertebral disc may be done to relieve pressure on the spinal cord. The discs are cushions between the vertebrae. After the disc is removed, the vertebrae may be fused together to provide stability. Metal plates, screws, or wires may be needed to hold vertebrae or pieces in place.
History
Arab physician and surgeon Ibn al-Quff (d. 1286 CE) described a treatment of cervical fractures through the oral route in his book Kitab al-ʿUmda fı Ṣinaʿa al-Jiraḥa (Book of Basics in the Art of Surgery).[3]
