METHOD FOR RECOVERY OF SPHERICITY OF HEAD OF HUMERUS IN SURGICAL TREATMENT OF PATIENTS WITH CHRONIC DISLOCATIONS OF SHOULDER Russian patent published in 2020 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for restoration of sphericity of head of humerus with using screws and bone cement during surgical treatment of patients with chronic dislocations of shoulder. Subchondral bone is resected from the defect area along the edge of the defect with formation of a bone shed with width of 1-3 mm and depth of 3-5 mm. Three screws are inserted into bottom of defective cavity so that their axes are located along ribs of conditional triangular pyramid with corners of vertex 30°-40°, and the screw heads are immersed deeper than the conditioned recovered spherical articular surface. Cavity of the defect is filled with bone cement, and an articular surface is formed under visual control of the accuracy of the transition of the cartilage of the head to the spherical surface of the cement. If there is an inflammatory process in the region of the head of the humerus in the past history, or signs of the infectious process revealed during the operation, bone cement with an antibiotic is used.

EFFECT: method enables recovering the sphericity of the articular surface of the head of humerus by using the methods of the declared method.
