Scapular, Clavicular, Acromioclavicular and Sternoclavicular Joint Injuries

The chapter starts with a short overview of the relevant anatomy of bones and surrounding soft tissues. Most of an imaging part is focused on plain radiography discussing routine views as well as relevant special views, followed by the role of ultrasound, CT, MRI, bone scintigraphy, and SPECT-CT. The main part of the chapter is dedicated to specific overuse trauma, including typical overuse lesions of the immature skeleton. Discussed bony lesions are fractures, the rare stress fractures of scapula and clavicle, stress-related growth plate injury of the coracoid process and medial clavicle, lateral acromial apophysitis, and distal clavicular osteolysis. Joint pathology comprises acromioclavicular and sternoclavicular sprain or dislocation and AC joint osteoarthritis. Typical nerve pathologies of this anatomical area are the suprascapular nerve entrapment and the long thoracic neuropathy.
