Minimally Invasive Resection of a Pediatric Lumbar Osteoblastoma: Case Report (original) (raw)

Operative Neurosurgery, 2020

Abstract

BACKGROUND Osteoblastomas are locally aggressive bone tumors typically affecting the posterior elements of the vertebral column. The treatment of choice is total surgical resection, traditionally through an open laminectomy, often with facetectomy and fusion when the lesion is in the foramen.

In this population especially, open surgery can be associated with significant impairment and morbidity. METHODS We report a pediatric case of posterior L5 osteoblastoma completely removed using a facet-sparing and fusion-avoiding contralateral foraminal minimally invasive approach using a tubular retractor system. A 12-yr-old male competitive tennis player presented with progressive right L5 lumbosciatica. Computed tomography scan and magnetic resonance imaging revealed a lesion of the right L5 pedicle, facet, and vertebral body...
