The lumbosacral lucent cleft, a spinal finding, is often associated with trauma. However, this study found it can appear in asymptomatic individuals, suggesting it may be innocuous.

Area of Science:

  • Radiology
  • Spinal Imaging
  • Orthopedics

Background:

  • The lumbosacral lucent cleft sign was initially linked to cervical spine trauma.
  • This study investigates the incidence and characteristics of the lucent cleft sign in patients without a history of trauma.

Purpose of the Study:

  • To determine the incidence of the lumbosacral lucent cleft sign in a local population.
  • To identify characteristic features of the lucent cleft sign.
  • To assess the clinical significance of the lucent cleft sign in asymptomatic individuals.

Main Methods:

  • Prospective examination of 430 lumbosacral spine radiographs over 8 months.
  • Correlation of radiographic findings with clinical data.
  • Follow-up radiographs at 1, 3, and 6 months for patients with the lucent cleft sign.

Main Results:

  • Nineteen patients (4.4%) exhibited lucent clefts in their lumbosacral spine X-rays.
  • Lucent clefts remained consistent in number and features over 6 months, even after symptom resolution.
  • All observed lucent clefts were linear, horizontal, and located at the anterior vertebral body edge.

Conclusions:

  • The lumbosacral lucent cleft sign may occur in the absence of spinal trauma.
  • This sign appears to be innocuous in patients with minimal or no symptoms.
  • Further research may clarify the etiology and clinical implications of this finding.
