Topic. Topographical anatomy of the scapular and deltoid regions. Surgical anatomy of the shoulder joint. Punction, arthrotomy and resection of the shoulder
joint. Topographical anatomy of the axillar region and shoulder region.
Relevance of the topic: diagnosing and treatment of the inflammations of the anterior and posterior prescapular gaps, osteofibrous compartments,
subdeltoid fibrous tissue, omarthritis and dislocations of the joint attract attention to the studying of this topic. Deep knowledge of the topographical anatomy of the
neurovascular bunches of the axillar region and shoulder are necessary for their exposure at the traumas and diseases.
