Is T12 L1 considered thoracic or lumbar?
Currently, T12-L1 is considered a thoracic level for both transforaminal and facet injections. For transforaminal approach at T12-L1, this is considered thru the T12 foramen where the T12 spinal nerve exits. For facet joint blocks, the T12-L1 facet joint receives innervation from the T11 and T12 medial branches.
