Background Information: Chest wall injuries may be overlooked in the acute setting due to their frequent association with more pressing life-threatening injuries. Severity of chest wall injuries varies: some injuries may be inherently life-threatening, while others may predispose to long term complications, particularly if overlooked. Participants will become familiar with the spectrum of chest wall injuries, with a focus on improving diagnosis in the acute setting and learn to recognize the potentially associated life-threatening injuries and long-term complications of chest wall injuries.

Educational Goals/Teaching Points: Participants will learn to recognize the imaging spectrum of osteoarticular chest wall injuries, with emphasis on features that affect management. We identify the imaging spectrum of pectoralis muscle and other chest wall muscle injuries and describe the potential life-threatening complications of some chest wall injuries. Viewers will recognize the potential long-term complications of chest wall injuries.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: The following will be discussed: sternal, clavicular, scapular and rib fractures: spectrum (with emphasis on pertinent imaging features), classification, treatment and complications; sternoclavicular dislocation, manubriosternal dislocation, AC joint separation, floating shoulder, scapulothoracic dissociation: spectrum (with emphasis on pertinent imaging features), classification, treatment and complications; and imaging of pectoralis major and other chest wall muscle injuries.

Conclusion: Chest wall injuries comprise a wide spectrum of injuries. These injuries may be overlooked in the acute setting. Awareness of the imaging spectrum of chest wall injures is important to improve the diagnosis and management of these conditions.
