Description

A thoracolumbar support device for reducing spinal compression fractures

technical field

The utility model relates to a thoracolumbar supporting device for resetting spinal compression fractures, which belongs to the technical field of medical instruments.

Background technique

Spinal fracture is a common trauma in orthopedics, accounting for 5% to 6% of fractures, and the highest incidence of thoracolumbar fractures, often accompanied by spinal cord injury. For spinal fractures, the principles of treatment are to relieve compression, correct deformities, and restore and maintain spinal stability. According to Denis's three-column theory, when the anterior column compression is <1° and the kyphosis angle is <30° in spinal compression fractures, the commonly used methods include two-table method, double-ankle suspension method, Climbing rope and stacking bricks method, pillow method, door climbing and stretching method, etc. Among them, the two-table method and the double-ankle suspension method generate traction through the hyperextension and extrusion of the thoracolumbar region. Most patients cannot tolerate and persist during the operation. , It is easy to cause reset failure and nerve damage. At present, the commonly used minimally invasive surgical treatment such as percutaneous vertebroplasty (PVP) has the advantages of small trauma, fast postoperative recovery, and less use of anesthesia, but it relies more on the experience of the surgeon, and there is a risk of accidentally injuring important anatomical structures. .

In the prior art, wearable braces for spinal compression fractures have the following two deficiencies:

1) Generally, it cannot act on the fracture plane accurately, so it generally only has the function of auxiliary positioning, but not the function of fracture plane reduction;

2) It cannot provide the axial expansion force of the spine, which is not conducive to the rehabilitation of the fracture site.
