TUBS classification stands for which of the following?

• A. Traumatic Unilateral Dislocations with Bankart lesion requiring Surgery
• B. Traumatic Upper Brachial Subluxation
• C. Tumor Under Bony structures
• D. Traumatic Unstable Bankart Syndromes

Answer: (A)

This item tests your knowledge of the shoulder instability pattern described by TUBS. TUBS stands for Traumatic, Unilateral, Bankart lesion, Surgery. It describes patients who have a single traumatic dislocation with an associated Bankart lesion, and who typically require surgical stabilization to prevent recurrent instability. The Bankart lesion is a detachment of the anteroinferior labrum (and often surrounding capsule) from the glenoid rim, which creates a mechanical instability that is commonly addressed with surgical repair. This pattern is contrasted with other presentations that are managed nonoperatively or involve different instability patterns, so the answer that aligns with the Traumatic Unilateral Bankart lesion requiring Surgery is the best fit.
