Postlaminoplasty kyphotic deformity in the thoracic spine: case report and review of the literature.

In the pediatric population, a strong correlation between multilevel laminectomy and postlaminectomy spinal deformities, predominantly kyphosis, has been demonstrated. This has been observed mainly in the cervical and thoracic spine. Therefore, laminoplasty was proposed as an alternative to laminectomy with a reduced incidence of spinal deformity and need for stabilization and fusion. Moreover, to the best of our knowledge, postlaminoplasty kyphosis of the thoracic spine has not been previously described in the literature. We report the case of a pediatric patient who rapidly developed severe thoracic kyphosis 3 months after resection of a symptomatic extradural spinal arachnoid cyst and multilevel en bloc thoracic laminoplasty, and review the relevant literature.
