Study design: A case report of a complication after posterior spinal fusion.
Objectives: To present the clinical findings of a Horner's syndrome after posterior spinal fusion.
Summary of background data: A 14-year-old girl underwent posterior spinal fusion for idiopathic scoliosis.
Methods: Clinical examination and pharmacologic pupillary testing were used to diagnose Horner's syndrome.
Results: After surgery, the patient developed a left-sided Horner's syndrome. The Horner's syndrome had resolved 6 months after surgery except for slight ptosis.
Conclusions: This is the first reported case of Horner's syndrome occurring after posterior spinal fusion without the use of epidural analgesia.
