Patellar fracture fixation splint

Abstract

The invention provides a patellar fracture fixation splint, belongs to the medical treatment and public health technology, and relates to the field of the department of orthopaedics, in particular to a patellar fracture fixation technology. The patellar fracture fixation splint comprises connecting nails and is characterized in that the connecting nails adopts screws, and the screws penetrate through screw holes in an annular shaping steel plate belt surrounding fractured patella and are tightly screwed on the fractured patella fit according to a fracture line; the femur, the tibia and the fibula surround the patella; the annular shaping steel plate belt bends like the patella and has alternate concave-convex distribution thicknesses, and the holes allowing penetration of the screws are formed in convex parts. The patellar fracture fixation splint has the benefits that good mechanical stability is achieved, and functional exercise of a patient is facilitated; the integrity of the annular structure is high, and the splint is suitable for fracture fixation of multiple patellae and has a large application range; blood supply influence on the patella surface is reduced due to the alternate concave-convex design, growth and union are promoted, and foreign body sensation of the patient is reduced; and the splint is convenient to use and operate.

Description

technical field [0001] It belongs to medical and health technology, and relates to the field of orthopedics, specifically about the fixation technology of patella fracture. Background technique [0002] Currently, the following methods are commonly used for fixing patellar fractures: cerclage fixation method: use 18-28 stainless steel wires, guided by a thick round needle, close to the patellar border and suture a circle in the surrounding soft tissue, then reset the patellar fracture, and place the steel wire Gradually tighten and tighten. This method is relatively simple, and the fixation is relatively complete, but it is prone to angular deformity, and is generally suitable for fractures with less displacement or comminuted fractures that can still be reduced; through-fixation method: use a 2mm drill on the proximal fracture fragment Drill a tunnel on the inner and outer sides of 1cm, perpendicular to the longitudinal axis of the patella; use the same method to drill a t...

Problems solved by technology

[0003] These methods have the disadvantages of cumbersome operation, high technical requirements, lack of integrity of each internal fixation, and general firmness.
