FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely traumatology and orthopaedics, and may be used in treating articular diseases and injuries with the use of transplants, e.g. chronic recurrent shoulder instability accompanied by formation of a bone defect of an articular process of shoulder blade. A guide pin comprises a body and a guide element with through holes. A handle is fixed on one end of the body. The body is bent in the form of a plate a central part of which has a flat surface extended by an articular scoop bent by a surface of articular head on the end opposite to the handle. The guiding element is fixed in the central part of the plate on its flat surface and has through holes parallel to each other and to the central flat part of the body, and used for inserting osteosynthesis pins and screws passing through the body of the guiding elements, a transplant and a source bone.

EFFECT: invention enables higher accuracy, lower number of injuries accompanying transplant insertion, providing more reliable fixation of a free bone auto- or homotransplant to the reconstructed joint defect, maximally preserving an articular surface congruence that shall lead to further probability of developing arthrosis deformans.
