T8: Definition, Uses, and Clinical Overview
T8 most commonly refers to the eighth thoracic vertebra in the middle of the back. It is one of the 12 thoracic spine bones (T1–T12) that connect to the ribs. Clinicians use “T8” to label a specific spine level on exams, imaging reports, and surgical plans. Depending on context, “T8” can also refer to the T8 spinal nerve/root region near that level.
