The work was grounded on the analysis of the examination data and treatment results of 130 patients with uncomplicated rotator cuff injuries. Clinical manifestation and radiographic findings were described for the different types of injuries. Differentiated methods for the treatment were suggested. Forty two patients with partial local cuff injuries were on conservative treatment. In 38 patients that treatment was successful and in 4 patients with degenerative cuff changes the treatment was failed. Ninety two patients were operated on. Good and excellent results were achieved in 90.2%) of cases, satisfactory and poor in 9.8%. Poor outcomes (4 patients) were resulted from formation of acromion pseudoarthrosis and development of wound infection, satisfactory outcomes (5) were resulted from cuff suture failure and scar development in defect plasty.
