AI Technical Summary

Problems solved by technology

Ankle joint injuries are generally very swollen, and the inferior tibiofibular syndesmosis is only separated by a few millimeters. Both plaster and splints are loose, and it is often difficult to achieve a fixed effect

Embodiment Construction

[0015] Refer to attached figure 1 , 2 , 3, 4 Separation of inferior tibiofibular syndesmosis combined with fracture hook plate internal fixator structure includes fibula fixation plate 3, tibiofibular retractor; fibula fixation plate and tibiofibular retractor are combined into one body, and the overall shape matches the anatomical part of human lower tibia and fibula. The fibula fixation plate 3 is provided with several fibula fixation holes 5, the fibula fixation holes 5 are long waist-shaped holes, the hole surface can be spherical, the fibula fixation plate 3 has a circular arc to coincide with the outer surface of the fibula, and the tibiofibular retractor has tibiofibular The retractor hook body 2 has a fibula retractor 4 at one end of the tibia-fibula retractor hook body 2, and a tibial fixation hole 1 at the other end of the tibia-fibula retractor hook body 2.

[0016] Refer to attached Figure 4 , Inferior tibiofibular syndesmosis separation combined with fracture h...

Abstract

An internal fixer of hook plate for treating distal tibiofibula separation caused by condylar fracture is composed of a fibula fixing plate with several fibula fixing holes and arc part matched with the fibula, and the tibiofibula pull-hook unit consisting of main body, pull hooks for fibula and tibia fixing holes.

Description

technical field [0001] The present invention relates to a hook plate internal fixator for syndesmosis separation combined with fracture, which relates to an internal fixation device for treating syndesmosis injury, separation and combined fracture caused by ankle joint fracture. Background technique [0002] As a weight-bearing joint, the ankle joint bears a lot of load in walking, standing, running and jumping postures, and the inferior tibiofibular syndesmosis is of great significance for maintaining the integrity and stability of the ankle point. According to Lauge-Hansen's classification of ankle joint fractures, supination and external rotation and pronation and abduction fractures all have varying degrees of syndesmotic injury, which accounts for more than 60% of ankle fractures. After the separation of the inferior tibiofibular syndesmosis, the stability of the ankle joint is destroyed, the ankle point widens, and the talus moves outward, the pressure per unit area in...
