Proximal humerus combined internal fixation system

Abstract

The invention discloses a proximal humerus combined internal fixation system, and belongs to the technical field of proximal humerus locking steel plates. The proximal humerus combined internal fixation system comprises a bone plate main body and fixing holes in the bone plate main body; the proximal humerus combined internal fixation system is characterized in that a greater tuberosity humerus hook plate, which is of an independent structure, and a lesser tuberosity humerus hook plate, which is of an independent structure, are matched with the bone plate main body; and in the system, the bone plate main body is independently fixed to a proximal humerus broken bone, or the bone plate main body is fixed to the proximal humerus broken bone in a mode of being matched with either the greater tuberosity humerus hook or the lesser tuberosity humerus hook plate or both of them, so as to adapt to different clinical demands. With the implementation of the proximal humerus combined internal fixation system disclosed by the invention, ideal fixation therapy can be conducted on different types of fractures of proximal humerus, so that four proximal humerus locking steel plates in the prior art can be replaced; moreover, the inner wall of the internal fixation system fits a main part of the proximal humerus in shape, so that the internal fixation system is high in strength and good in stability on fixing the proximal humerus fractures, and the internal fixation system can effectively reduce the occurrence of nail withdrawal and nail breakage complications after an operation.

Description

technical field [0001] The invention belongs to the technical field of locking steel plates at the proximal end of the humerus, and in particular relates to a combined internal fixation system at the proximal end of the humerus. Background technique [0002] Proximal humeral fractures are one of the common fractures, accounting for about 5% of all fractures clinically. According to the report of the "Eleventh Five-Year" National Science and Technology Support Project led by Professor Jiang Baoguo from the Department of Traumatology and Orthopedics of Peking University People's Hospital, a total of 2,338 patients with periarticular fractures with complete follow-up data were collected from the affiliated hospitals of 5 universities across the country. There were 315 cases of terminal fractures, accounting for 13.5%. For this reason, people have proposed many technical schemes about "proximal humerus bone plate", such as publication number: CN104586494A "proximal humerus bone...
