Problems solved by technology

Since the plate is placed in the same position, the locking nail will also be placed in the same position as the first operation, which will lead to weak fixation and even failure of the second operation

Embodiment 2

[0016] More than 1 year after the operation for the distal femur fracture, the patient suffered from nonunion and fracture of the steel plate. If the same type of steel plate is used for revision, because the steel plate is an anatomical steel plate, the placement position is fixed and the nail holes are fixed, so the fixation is not firm. If the dry plate of the present invention is adopted, the diameter of the nail holes and nails increases, which can be effectively fixed. At the same time, the setting of the holding section increases the area of ​​the far end of the steel plate body (the lower end of the steel plate body), further increasing the holding force.

Abstract

The invention discloses a distal femur dissection locking revision steel plate which comprises a steel plate body with nail holes. The diameter of the nail holes is larger than that of nail holes of adissection locking plate originally fixed to the distal femur, the far end of the steel plate body is provided with a handheld section which is provided with nail holes, and the handheld section andthe steel plate body are formed integrally. After diameter increasing of the nail holes and nails, bone tissue holding force is remarkably increased, and the problem of failure in effective fixing inapplication of a conventional steel plate to revision is effectively solved.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to a steel plate used in revision surgery of nonunion after distal femur fracture. Background technique [0002] Fractures of the distal femur account for about 6% of all fractures in the whole body. They are fractures near the joint, and the conservative treatment effect is poor. Most scholars advocate surgical treatment. Anatomical locking plate internal fixation through the lateral approach has gradually become a classic treatment for distal femoral fractures. Internal fixation method. Although surgical treatment has achieved good results, postoperative nonunion and internal fixation fractures have been reported in the literature. For patients with broken internal fixation, when the revision operation is performed again, since the lateral plate is an anatomically locked plate, when the same type of plate is selected again, it is often placed in the same position as the first operatio...
