The application discloses a cutting guide plate for a proximal tibia and a preparation method thereof, and belongs to the technical field of orthopedic cutting guide plates. The cutting guide plate comprises a positioning plate, the bottom surface of the positioning plate is attached to a tibial articular surface and lateral bone, a cutting groove is formed in the side surface of the positioning plate, the cutting groove is inclined backward by 3-5 degrees, an avoiding hole is formed in the top surface of the positioning plate, and at least two fixing holes are arranged on the positioning plate; and a positioning line is arranged on the upper end surface of the positioning plate, and the positioning line is used for pointing to the inner 1 / 3 of a tibial tuberosity. The cutting guide plate is used for tibial cutting surgery, effectively improves the cutting and prosthesis installation accuracy, shortens the operation time, reduces the operation complications, and helps the patient to quickly recover.

Disclosed are surgical constructs, assemblies, and methods for the repair and reconstruction of the elbow. The rotation center guide has specific dimensions configured to be fixed to either the lateral or medial side of the elbow. At one end, the guide is provided with multiple full concentric through-holes (circles of different diameters) having bisectors at 90-degree intervals to identify the rotation center on the lateral and medial epicondyles. At the other end, the guide is provided with a linear pattern of through-holes or openings located around the centerline of the guide. The linear pattern of through-holes identifies the attachment point on the ulnar tubercle. The through-holes in the concentric and linear patterns of the guide are sized to receive instruments such as K-wires, guides, and / or drill guides. One or more spikes or points are provided at the bottom of the guide for stabilization during use.
