Thickening of the laminar arch and facet joints can cause thoracic spinal stenosis. Surgical decompression improved symptoms in most patients, highlighting the importance of accurate diagnosis via CT scans.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Radiology

Background:

  • Thoracic spinal stenosis is a condition characterized by narrowing of the spinal canal in the thoracic region.
  • Common causes include degenerative changes, disc herniations, and congenital abnormalities.
  • Thickening of the laminar arch and facet joints is a less common etiology.
  • Claudication, a symptom of leg pain worsened by walking, is a prominent feature.

Purpose of the Study:

  • To report on seven cases of thoracic spinal stenosis caused by thickening of the laminar arch and facet joints.
  • To describe the clinical presentation, diagnostic methods, and treatment outcomes for this specific condition.
  • To review the existing literature on this rare cause of thoracic spinal stenosis.

Main Methods:

  • Case series reporting on seven patients with thoracic spinal stenosis.
  • Clinical evaluation including assessment of motor and sensory deficits.
  • Diagnostic imaging using computerized tomography (CT) scans.
  • Surgical intervention involving extensive posterior decompression and medial facetectomy.

Main Results:

  • Seven cases of thoracic spinal stenosis were identified.
  • Prominent clinical feature was neurogenic claudication.
  • All patients exhibited motor and sensory abnormalities.
  • Computerized tomography scans were crucial for diagnosis.
  • Five of seven patients showed satisfactory improvement after surgical decompression.

Conclusions:

  • Thickening of the laminar arch and facet joints is a treatable cause of thoracic spinal stenosis.
  • Early diagnosis with CT imaging is essential for effective management.
  • Posterior decompression with medial facetectomy can lead to significant clinical improvement.
