Reliability of a novel classification system for thoracolumbar injuries: the Thoracolumbar Injury Severity Score.

Study Design: Prospective study of 5 spine surgeons rating 71 clinical cases of thoracolumbar spinal injuries using the Thoracolumbar Injury Severity Score (TLISS) and then re-rating the cases in a different order 1 month later.

Objective: To determine the reliability of the TLISS system.

Summary Of Background Data: The TLISS is a recently introduced classification system for thoracolumbar spinal column injures designed to simplify injury classification and facilitate treatment decision making.

The accessory navicular.

The accessory navicular is a common presence in the human foot and must be included in the differential diagnosis of medial foot pain in patients who are of appropriate age. Imaging modalities aid in diagnosis of a symptomatic ossicle and guide classification and treatment. Often, a combination of studies is needed to establish an accessory navicular as the source of foot pathology.
