[0026] This embodiment provides a radial head bone plate, which includes a head bone plate 1 and a main body bone plate 2 fixedly connected to the head bone plate 1. The head bone plate 1 is in an arc shape matching the circumferential shape of the human radial head 01, and the main body bone plate 2 matches the part of the human radius 02 extending from the proximal end of the radius 02 to the distal end of the radius 02. A plurality of first screw holes 11 for fixing the head bone plate 1 to the radial head 01 are provided on the head bone plate 1, and a plurality of second screw holes 21 for fixing the main body bone plate 2 to the radius 02 are provided on the main body bone plate 2.
[0027] In this embodiment, the head bone plate 1 is circumferentially matched with the radial head 01 of the human body, and the main body bone plate 2 is matched with the part of the radius 02 of the human body that extends from the proximal end of the radius 02 to the distal end of the radius 02. It is an anatomical design that can solve the problem of comminuted fracture of the radial head 01 and the problem of insecure fixation, and avoid intraoperative shaping, reducing the operation time. In this embodiment, first screw holes 11 and second screw holes 21 are respectively arranged on the head bone plate 1 and the main body bone plate 2, and the anatomical design of the head bone plate 1 and the main body bone plate 2 enables the radial head bone plate to be fixed by using the screw holes when fixed, so that the thickness of the bone plate can be reduced, and the thickness can reach 1 mm.
[0028] The number of the main body bone plates 2 is two, and the two main body bone plates 2 are parallel to each other. The second screw holes 21 of each main body bone plate 2 are distributed at intervals along the length direction of the main body bone plate 2, and the second screw holes 21 of the two main body bone plates 2 are arranged in a staggered manner in the length direction of the radius 02. It can firmly fix the main fracture fragments of the radius 02, and the staggered arrangement of the second screw holes 21 of the two main body bone plates 2 in the length direction of the radius 02 can effectively avoid the locking interference of the corresponding position screws, and avoid the problems of insecure fixation and poor torsional performance.
[0029] Multiple first screw holes 11 are distributed at intervals along the length direction of the head bone plate 1, and the axis of the first screw hole 11 is perpendicular to the plate surface of the head bone plate 1 at the position where the first screw hole 11 is located. The head bone plate 1 surrounds 1 / 3 of the circumference of the radial head 01. The number of the first screw holes 11 on the head bone plate 1 is 3 - 7. The above characteristics of the head bone plate 1 can achieve stable fixation of the fracture fragments.
[0030] The number of the second screw holes 21 on each main body bone plate 2 is 3 - 7 respectively, and can be adjusted and designed according to the fracture range.
[0031] Each main body bone plate 2 is arranged at an obtuse angle with the end of the adjacent head bone plate 1, and the obtuse angle range is between 100 - 120°, making the bone plate design more in line with the anatomical design of the radial head 01.
[0032] The surfaces of the head bone plate 1 and the main body bone plate 2 are rounded, and the ultra-low incision reduces the irritation to soft tissues.
[0033] The head bone plate 1 and the main body bone plate 2 are of an integral structure, with stable structure and good fixation effect.
[0034] In this embodiment, both the head bone plate 1 and the main body bone plate 2 are wavy, which can reduce the area and weight of the overall bone plate, reducing the discomfort of the patient after implantation.
