Description

Traction and reduction frame for calf fracture

technical field

The invention belongs to the field of medical devices, in particular to a traction reduction frame for calf fractures.

Background technique

The tibia and fibula of the lower leg are the most frequently fractured long tubular bones, accounting for about 10% of total body fractures, and traffic injuries are the most common. Because the anteromedial tibia is located under the skin, fractures are often serious, and most require surgical treatment. Traction is required both before and during the operation. The Brownian frame has no resistance before the operation, and the weight of the traction is more lost. Slow and continuous traction is required. The fracture end can move, and the patient has obvious pain. The fixed bracket also requires manual traction during the operation. It is often difficult to reset without resisting traction, and it is difficult to maintain even if it is reset. Especially for young people who are muscular, open reduction is often required. Non-union rates increased. Some hospitals are equipped with fracture operating beds to meet traction, but they are bulky, cumbersome to install, and local cross-bar supports increase the risk of nerve injury. Standard orthopedic operating tables are difficult to maintain without bone traction devices, and difficult to reset. The fracture spreader is a unilateral external fixation bracket, which requires screws to be screwed into the distal and proximal ends of the tibia unilaterally, which may lead to iatrogenic fractures of the distal and proximal tibia during the distraction process.

At present, there is no anti-traction, intraoperative auxiliary reduction device or stent clinically.
