Insights

Pediatric posterior spinal surgery can rarely cause Horner

Area of Science:

  • Pediatric Neurosurgery
  • Ophthalmology
  • Spinal Surgery

Background:

  • Horner's syndrome is characterized by unilateral ptosis, miosis, and anhidrosis.
  • It is a rare complication following posterior spinal surgery in children.
  • The oculosympathetic pathway is vulnerable during cervicothoracic region surgery.

Purpose of the Study:

  • To highlight Horner's syndrome as a rare complication of posterior spinal surgery in pediatric patients.
  • To present a case series of pediatric patients who developed Horner's syndrome postoperatively.

Main Methods:

  • A case series of three pediatric patients is presented.
  • All patients underwent posterior spinal fusion involving the cervicothoracic region.
  • Postoperative symptoms of miosis and ptosis were monitored.

Main Results:

  • Three pediatric patients developed acquired Horner's syndrome after spinal surgery.
  • Cases included patients with DiGeorge syndrome, congenital scoliosis, and Klippel-Feil syndrome.
  • Symptoms included unilateral miosis or ptosis.

Conclusions:

  • Horner's syndrome is a rare but possible complication of pediatric posterior spinal fusion.
  • Injury to the oculosympathetic pathway can occur during cervicothoracic deformity correction.
  • Potential mechanisms include traction injury or nerve root transection.
