Humeral greater tuberosity compression locking steel plate

Abstract

The invention discloses a humeral greater tuberosity compression locking steel plate which comprises a steel plate body and screws. The steel plate body is a triangular steel plate without closed angles. The steel plate body is arc-shaped. Three screw holes are formed in the surface of the steel plate body. The screws are vertically mounted on the surface of the steel plate body. Three kirschner wire fixing holes are formed in the middle of the steel plate. Rotator cuff sewing holes are designed at the edge of the steel plate body. The humeral greater tuberosity compression locking steel plate has the advantages that the steel plate is made into a spherical surface conforming to humeral head anatomy to increase containment and compression of the steel plate to fractured bone blocks or crushed bone blocks, the screws are fixed with the steel plate in an angled manner to increase vertical pulling out force resistance, the steel plate is designed into the size only fixing a humeral greater tuberosity to facilitate minimally invasive operations, and the problem that the crushed fractured bone blocks cannot be fixed by the screws is solved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a pressurized locking steel plate for the greater tuberosity of the humerus. Background technique [0002] For greater tuberosity fractures of humerus, there is no special steel plate at present, only hollow screw fixation, the fixation strength of the screws is not enough and it is easy to break the fracture fragments, the use of screw fixation requires that the fracture fragments of the greater tuberosity of the humerus must be large enough, if the fracture fragments are crushed, it cannot fixed. Contents of the invention [0003] The purpose of the present invention is to provide a greater tuberosity compression locking plate, which aims to solve the problem that the greater tuberosity fracture fragment must be large enough to fix the greater tuberosity fracture with screws, and if the fracture fragment is crushed, it cannot be fixed. [0004] The present invention is realize...
