Anterior stabilization, instrumentation, and decompression for post-traumatic kyphosis

Thirty-seven patients underwent surgery for late post-traumatic kyphosis in the lumbar, thoracolumbar, or thoracic spine. Indications for surgery included: increasing deformity, pain, and persistent neurologic deficit with paraparesis in eight, and development of late spinal stenosis in a further nine patients. All patients underwent anterior correction with Kostuik-Harrington instrumentation. Seventeen patients with neurologic deficit underwent decompression over appropriate levels as well. No posterior fusions or instrumentation were carried out. Stable arthrodesis with correction of the deformity occurred in 36 of 37 patients with only one nonunion. Pain was reduced significantly in 78% of patients. Late neurologic improvement of a significant functional degree occurred in three of eight paraparetics. All patients with spinal stenosis had relief of their symptoms and signs.
