Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the mid-twentieth century. An internal fixator may be made of stainless steel, titanium alloy, or cobalt-chrome alloy.

The invention discloses a posterior reduction internal fixation system. The posterior reduction internal fixation system comprises two vertebral body orthopedic rods arranged in parallel and an adjusting device. During operation, the connecting rods of the two vertebral body orthopedic rods are connected with a vertebral body, and an occipital bone plate is connected with an occipital bone, so that the posterior reduction internal fixation system is connected with the occipital bone and the vertebral body; the base assembly is connected with a pedicle screw close to an occipital bone, and theconnecting assembly is connected with an occipital bone screw; the inclination angle between the occipital bone plate and the connecting rod is adjusted, specifically, the connecting rod is driven bythe first linear driving assembly to move, the first drag hook and the second drag hook are connected with two occipital bone screws on the occipital bone correspondingly, and the first linear drivingassembly is driven by the second linear driving assembly to move; the first linear driving assembly drives the connecting rod and the first drag hook and the second drag hook on the connecting rod tomove, the occipital bone is lifted and dragged, the inclination angle between the occipital bone plate and the connecting rod is made to conform to the anatomical structure of the occipital bone andthe cervical vertebra of the human body, and posterior reduction internal fixation is achieved.

Dynamic locking plate for treating fracture of neck of femur

The invention provides a dynamic locking plate for treating a fracture of a neck of a femur. The dynamic locking plate comprises a tuberosity supporting plate and three locking screw holes, wherein the inner surface of the tuberosity supporting plate is bent to be matched with the lower part of a greater trochanter of the femur in shape; the positions of the three locking screw holes including a first locking screw hole, a second locking screw hole and a third locking screw hole in the tuberosity supporting plate are based on a locating point A at the middle of the tuberosity supporting plate, and distributed around the locating point A; the first locking screw hole, the second locking screw hole and the third locking screw hole are distributed to form a triangle in the tuberosity supporting plate; axes of the three locking screw holes are parallel; based on a vertical line AO of the tuberosity supporting plate where the locating point A is positioned, the axial lines of the three locking screw holes are inclined upwards and form longitudinal included angles theta with the vertical line AO, which are equal to 15-35 degrees. The locating point A is located within the range that the geometric center of the tuberosity supporting plate is taken as a center, and the diameter is 4 mm. The dynamic locking plate enables the broken end of a fractured bone to be subjected to micro-movement and compression, and adapts to dynamic characteristics of bone growth when improving the internal fixation stability of the neck of the femur, so as to be more beneficial to healing of the broken end of the fractured bone.
