[Injuries of the supraspinatus muscle within the structure of humeroscapular periarthroses and their surgical treatment].

The collective diagnosis of humeroscapular periarthritis (HSP) may imply a number of diseases different both in the genesis (inflammation, a degenerative process, trauma, cervical osteochondrosis) and localization (tendons of the humeral short rotators, biceps, synovial sheaths, bursae, etc.). A large proportion of HSPs are inveterate lesions of musculus interspinalis requiring surgical intervention. Despite the analogous pattern of many clinical symptoms, close collaboration of neuropathologists and traumatologists may allow the differential diagnosis of primary and secondary HSPs.
