TECHNICAL FIELD

[0001] The utility model relates to the technical field of orthopedics implant medical instrument, concretely is a claw type humerus fracture bone plate. BACKGROUND

[0002] Fracture is the common injury form in orthopedics clinic. Among them, humerus fracture ranks the third in many common fractures. In the patient group over 65 years old, proximal humerus fracture accounts for 10% of the total number of fractures, and proximal humerus fracture seriously affects the life quality of the elderly. According to the fracture site and fracture degree, the existing proximal humerus fracture treatment methods mainly include external fixation frame fixation, kirschner wire internal fixation, suture fixation, locking bone plate system internal fixation, intramedullary nail internal fixation, shoulder joint replacement, bone graft or implantation of bone cement application, etc. Among these clinical treatment methods, metal or alloy type locking bone plate is widely used.

[0006] Both the fixing holes are taper threaded holes with a diameter of 3.5-5mm, and the outer circle is 8-10mm.

[0007] In order to better fix and reset the fracture position, as a claw type humerus fracture bone plate of the utility model, the total length of the bone plate is 90-120mm, and the width and thickness of the bone plate are 12-14mm and 3-3.5mm respectively.

[0008] In order to suture the fracture position, as a claw type humerus fracture bone plate of the utility model, the diameter of the second suture hole is 2mm.

[0009] In order to make the claw-shaped protrusion and the larger humeral tuberosity fracture position more fit, as a claw-shaped humeral fracture bone plate of the utility model is optimized, the side wall of the claw-shaped protrusion is provided with a concave groove between the two fixing holes.

[0010] Compared with the prior art, the utility model has the beneficial effects as follows:

[0011] The utility model discloses first fit the bone plate with the humeral fracture position, and is connected with the support threaded hole through the external screw, and the claw-shaped protrusion can assist the fixation of the larger humeral tuberosity fracture fragment bone, second, the first suture hole and the three second suture holes cooperate with each other to be convenient for the fracture position fixation suture, and then through the bone plate, the claw-shaped protrusion, the fixing hole and the first suture hole and the second suture hole cooperation, when the human humeral fracture, especially the proximal humeral fracture, the product can be implanted on the bone surface, and the fracture part of the humerus is fixed through the bone screw, so as to help the fracture recovery.
