Latissimus dorsi (LD) and teres major (TMA) injuries are increasingly recognized as significant sources of pain in overhead athletes, particularly pitchers. These injuries are challenging to diagnose clinically, and conventional MRI often lacks sufficient detail to fully evaluate them. Musculoskeletal ultrasound (US) offers dynamic, high‐resolution evaluation and may better characterize these injuries. This pictorial review illustrates the sonographic appearance of common LD and TMA injuries, aiming to enhance diagnostic accuracy, increase clinician familiarity with this region, and support future research in injury classification using ultrasound.

Ultrasound imaging is vital for musculoskeletal assessment due to its real‐time, high‐resolution capabilities and safety. While protocols exist for rotator cuff evaluation, comprehensive guidelines for imaging the latissimus dorsi and teres major muscles are lacking. This article fills this gap by presenting a detailed ultrasound protocol for these muscles, essential for shoulder stability and movement in overhead athletes. We review their anatomy, propose a standardized examination approach, and discuss clinical indications, aiming to improve diagnostic accuracy and management of these injuries.
