Abstract

Multiple anterior and posterior approaches to the thoracic disc space have been reported. However, we are not aware of any previous reports describing a transforaminal approach for thoracic disc release and interbody cage placement. In this case report, we describe a method to perform transforaminal thoracic interbody fusion (TTIF), which is an adaptation of an established lumbar fusion technique (transforaminal lumbar interbody fusion). Key differences between the two procedures are discussed. A 24-year-old woman presented after sustaining a T11-12 Chance fracture that had been treated in a brace. She had severe, debilitating pain and a rigid segmental kyphotic deformity of 38°. The patient was treated 3 months post-injury with T10-L1 fusion with anterior release and interbody fusion with cage placement at T11-12. Anterior column release and fusion were performed via a transforaminal approach. The patient had anatomic reduction of deformity, solid arthrodesis, and relief of pain at 1-year follow-up. The TTIF approach permits access to the anterior column of the thoracic spine for the purpose of reduction of deformity and interbody fusion with reduced morbidity compared to anterior–posterior surgery.
