METHOD OF HUMERAL RECONSTRUCTION ACCOMPANYING HYPOTROPHIC PSEUDOARTHROSIS Russian patent published in 2019 - IPC A61B17/62 A61B17/56 A61B17/72 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopedics, and can be used for surgical reconstruction of long tubular bones in false joints. Fragment of fibula of fibus is separated. Autograft is formed from it in the form of a bone pin. Autograft injection is closed and antegraded into a medullary canal of the humerus, overlapping the intramedullary zone of pseudarthrostasis. That is ensured by forming an insertion point from the proximal end of the humerus on the side of the head. In the humerus, a canal is formed, which corresponds to the size and geometrically is a continuation of the medullary canal of the humerus, longitudinal skin incision is made with length of not more than 15 mm, soft tissues pass, medullary canal is opened, and reamer is equal to the largest transverse size of the autograft along the diameter and passes into intramedullary canal. Marrowy canal is expanded to achieve pseudoarthrosis. Pseudartharthrosis area is opened, the formed end plates are destructed at the ends of the fragments of the humerus, the ends of the fragments are adapted to form a localized osteoplastic material. Distal and proximal fragments of the humerus are compared to an anatomically correct position, so that when they are fixed in preset position medullary canal of distal fragment is continuation of medullary canal of proximal fragment. Keeping the fragments in the achieved position, the reamer pass along the medullary canal of the proximal fragment to a depth of at least 10 mm and not more than to the level of the metaphysis. Autograft is inserted into the formed canal so that its one end is located in the proximal fragment, and the other end is in the distal fragment. Shoulder bone is fixed by compression-distraction apparatus (CDA), after fracture of fragments CDA is removed.

EFFECT: method provides minimally invasive stabilization of bone fragments and reduced length of consolidation and restoration of bone function ensured by using the autograft.
