What is a distraction spinal injury?

Abstract. Object: Flexion-distraction injuries occur due to distractive forces causing disruption of the posterior and middle spinal columns. These fractures classically consist of a fracture line through the posterior bony elements; involvement of the posterior ligamentous complex is, however, common.

What is meant by distracting injury?

The NEXUS study defined distracting painful injuries as injuries which are severe enough to distract the patient’s attention away from a second injury and may serve as markers of high energy trauma capable of producing multiple injuries.

What are mechanisms of spine injury?

Methods: The essential mechanisms of spinal injuries are considered: (1) axial deformation with (a) compression (centric or eccentric), most often eccentric, including compression in flexion or extension; (b) spinal elongation with distraction as centric elongation, but frequently axial eccentric elongation and a …

What is a distracting injury EMS?

Distracting injury is part of the clinical assessment for CSI when using NEXUS criteria. It was vaguely defined in that study on purpose but is generally thought to include severe extremity fractures, degloving injuries, severe burns, etc.

What defines a distracting injury in cervical spine assessment?

NEXUS, a national, multicentered prospective study that included more than 34,000 patients, defined distracting injury as any of the following: a long-bone fracture; visceral injury requiring surgical consultation; large laceration; degloving or crush injury; large burns; any other injury producing acute functional …

What is distraction force?

A force applied to a body part to separate bony fragments or joint surfaces. [L. dis-traho, pp. – tractus, to pull in different directions]

What is an extension injury?

Extension injuries. Hyperextension injuries. An extension force to the cervical spine can cause a wide spectrum of injury patterns ranging from the stable and relatively innocuous spinous process fracture to the highly unstable atlanto-occipital or posterior atlantoaxial dislocation (AAD).

Which is most common mechanism of spinal fracture?

Accidental falls and road traffic crashes (RTCs) were the most common mechanisms of spinal fractures (47.2% and 44.1%, respectively). RTCs tended to occur in younger patients compared with accidental falls.

Which of the following is the most common mechanism for spinal trauma?

The most common causes of spinal cord injuries in the United States are: Motor vehicle accidents. Auto and motorcycle accidents are the leading cause of spinal cord injuries, accounting for almost half of new spinal cord injuries each year. Falls.

What is selective spinal immobilization?

6.03 SELECTIVE SPINAL IMMOBILIZATION. Background: This parameter is intended to provide personnel with a guideline for the selective exclusion from spinal restriction on patients who have a low index of suspicion mechanism of injury for spinal injury combined with a thorough assessment that supports the exclusion.

What is a distracting injury in nexus criteria?

What are the mechanisms for serious neck injuries?

Six mechanisms are described, taking into account the direction of impact and the position of the head and neck at time of injury: compressive flexion, vertical compression, distractive flexion, compressive extension, distractive extension and lateral flexion.

What is distraction in orthopedics?

Distraction osteogenesis is a way to make a longer bone out of a shorter one. After a bone is cut during surgery, a device called a distractor pulls the 2 pieces of bone apart slowly. The slow stretching apart of bone is not painful. Children say it hurts less than braces they wear to straighten teeth.

What is a distraction in medical terms?

Listen to pronunciation. (dis-TRAK-shun) In medicine, a pain relief method that takes the patient’s attention away from the pain.

What are Nexus and C spine criteria?

Clears patients from cervical spine fracture clinically, without imaging. The NEXUS Criteria represent a well-validated clinical decision aid that can be used to safely rule out cervical spine injury in alert, stable trauma patients without the need to obtain radiographic images.

What is spine extension?

Back extension is a type of stabilization exercise used in back rehabilitation programs that involves bending the spine backwards.

What is a flexion injury?

Flexion or forward hinging injuries are most common in the lumbar spine following a fall in the bent position or an object falling on the bent back. The injury is stable if the posterior ligament remains intact, but the front of the vertebral body usually collapses.

What is the most common mechanism of injury for cervical spine injuries?

Trauma is the most common cause of cervical injury, and this can include motor vehicle accidents, falls, penetrating or blunt trauma, sports-related or diving injuries. [4][5] Nontraumatic causes can include compression fractures from osteoporosis, arthritis, or cancer and inflammation of the spinal cord.

What are the types of spinal cord injuries?

There are three types of complete spinal cord injuries:

• Tetraplegia.
• Paraplegia.
• Triplegia.

What is a distracting injury?

Distracting injury is part of the clinical assessment for CSI when using NEXUS criteria. It was vaguely defined in that study on purpose but is generally thought to include severe extremity fractures, degloving injuries, severe burns, etc.

What is a distracting injury to the cervical spine?

Upper torso injuries may be sufficiently painful to distract from a reliable cervical spine examination. Patients may detect spine tenderness in the presence of isolated painful lower torso inj … The National Emergency X-Radiography Utilization Study definition of a distracting injury may be narrowed.

Does distracting injury matter in clinical clearance of the C-spine?

Clinical clearance of the c-spine missed an equal number of c-spine injuries (CSI) on CT (10-13%) whether distracting injury (DI) was present or not. Why does this matter? Distracting injury is part of the clinical assessment for CSI when using NEXUS criteria.

Why is it important to understand the mechanism of injury?

MECHANISM OF INJURY. Physiologic damage, such as central nervous system injury, may be permanent despite the healing process. The mechanism of injury can help explain the type of injury, predict eventual outcome, and identify common injury combinations. Knowledge of this information improves trauma patient management.
