METHOD FOR SURGICAL TREATMENT OF BONE DEFECTS OF GLENOID PROCESS OF SCAPULA IN REVERSE SHOULDER REPLACEMENT Russian patent published in 2024 - IPC A61B17/56 A61F2/40 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for treatment of bone defects of glenoid process of scapula. According to the CT data, a computer three-dimensional model of the injured shoulder joint is constructed, designing a virtual model of an individual implant taking into account the post-traumatic defect of the glenoid process of the scapula and a mirror copy of the three-dimensional model of the glenoid process of the intact contralateral joint in the form of a long-stemmed metaglen and a lateralizing augment in the proximal portion corresponding to the edge of the glenoid defect, and in the distal portion corresponding to the officinal component of the endoprosthesis. Surface of the implant in the zone of contact with the bone is made porous. Holes are modelled for fixation of the implant with screws in the specified direction. Individual implant is made from titanium-aluminium-vanadium alloy on 3D-printer. Endoprosthesis replacement is performed. Method allows increasing the efficiency of the surgical treatment due to the restoration of the glenoid process of the scapula to conform to the anatomical shape, provides sufficient lateralization of the glenoid process of the scapula influencing the recovery of the biomechanics of the shoulder joint.

EFFECT: method provides higher efficiency of surgical treatment due to restoration of glenoid process of scapula to compliance with anatomical shape, providing sufficient lateralization of glenoid process of shoulder blade, which influences recovery of biomechanics of shoulder joint.
