From the Guidelines

A grade one anterolisthesis of the cervical spine is a mild forward slippage of one vertebra over the vertebra below it in the neck region, where the displacement is less than 25% of the vertebral width. This condition can result from various factors including degenerative changes, trauma, congenital abnormalities, or instability of the supporting structures [no specific reference provided as this is general medical knowledge].

Key Points to Consider

  • The diagnosis of cervical spine injuries, including anterolisthesis, often involves radiographic imaging, with the sensitivity of two or more radiographic views for detecting cervical spine injury being around 90% 1.
  • While CT scans are highly sensitive for detecting bony abnormalities, MRI is considered the reference standard for evaluating soft tissues and is particularly useful in cases with abnormal neurological examinations 1.
  • Treatment for grade one anterolisthesis typically starts with conservative management, including physical therapy, pain management with medications like ibuprofen, and possibly the use of a cervical collar for temporary support [no specific reference provided as this is general medical knowledge].
  • Surgical intervention is usually reserved for cases with progressive neurological deficits or intractable pain, emphasizing the importance of monitoring the condition to prevent progression [no specific reference provided as this is general medical knowledge].

Considerations for Imaging

  • The choice of imaging modality depends on the clinical presentation and the need to evaluate bony structures versus soft tissues 1.
  • For children, the use of MRI is recommended for suspected spinal cord or spinal column injury, especially if there's a prediction of prolonged unconsciousness or difficulty in clinical clearance within 72 hours 1.
  • The role of CT scans in pediatric patients is more limited compared to adults, due to the higher sensitivity of radiographs and MRI in detecting pediatric spine fractures and soft-tissue injuries 1.

From the Research

Definition of Anterolisthesis

  • Anterolisthesis refers to a condition where a vertebra in the spine slips forward, out of place, in relation to the vertebra below it 2.
  • This condition can occur in any part of the spine, including the cervical spine.

Grade of Anterolisthesis

  • The grade of anterolisthesis is determined by the degree of slippage, which is typically measured in millimeters or as a percentage of the vertebral body 2.
  • A grade one anterolisthesis of the cervical spine would indicate a mild degree of slippage, although the exact measurement or percentage is not specified in the provided studies.

Cervical Spine Anterolisthesis

  • Degenerative spondylolisthesis of the cervical spine has received insufficient attention compared to that of the lumbar spine 2.
  • Anterolisthesis of the cervical spine can be associated with cervical spondylotic myelopathy (CSM) in the elderly, and may cause intense cord compression seen on MRI scans 2.
  • The impact of anterolisthesis on the development of CSM may be greater than that of retrolisthesis, although the degree of displacement and cervical mobility may not differ significantly between the two conditions 2.

Diagnosis and Management

  • Diagnosis of anterolisthesis typically involves radiographic evaluation, such as X-rays or MRI scans 2.
  • Management of anterolisthesis may involve conservative strategies, such as physical therapy and pain management, although surgical options may be considered in severe cases or when conservative management fails 3, 4.
