Background

Scoliosis refers to the occurrence of lateral bulges, curvature deformities (medical term: coronal deformity) of the spine, and international scoliosis research has a definition that the curvature of the spine in the coronal plane is greater than 10 degrees. Scoliosis most commonly occurs during a sudden acceleration of growth and development prior to puberty. In most cases, scoliosis is more occult, but some children have spinal deformities that become very severe with development. Severe scoliosis can be very dangerous and can reduce the thoracic space, making it difficult for the lungs to function properly, thereby affecting the patient's respiratory function and even cardiac function.

Symptoms and signs of scoliosis often include: the shoulders are not equal in height; spinal curvature and rotation; one side of the scapula is protruded; uneven waist; the two hips are not of equal height. If the degree of scoliosis becomes greater, the spine will rotate or twist in addition to the lateral curvature of the spine. This can lead to bilateral rib asymmetric growth, resulting in thoracic deformities. Severe scoliosis can cause back pain and dyspnea.

Moderate to severe scoliosis may cause a range of complications, including:

1. the cardiopulmonary function is impaired. Thoracic deformity caused by severe scoliosis leads to severe compression on heart and lung, so that the growth and development of heart and lung are limited and the heart and lung function is incomplete, particularly as dyspnea and systemic ischemia and hypoxia;

2. as scoliosis progresses, more severe changes in appearance may result (including uneven shoulders, protruding ribs, hip asymmetry, lateral displacement of the waist and torso);

3. the old and middle-aged people with scoliosis are more likely to suffer from nervous symptoms such as chronic back pain, lumbocrural pain and the like;

4. scoliosis often puts a great psychological stress on the patient; affecting the normal psychological development of children.

Clinically, for a patient with moderate or severe scoliosis, a surgeon needs to perform reduction correction on the spine with severe scoliosis and restore the physiological curvature of the spine, and also needs to support, reduce and correct ribs with deformed and collapsed scoliosis and restore the thorax of the patient.

In order to restore the thorax of a patient, an orthopedist needs a surgical instrument which can be implanted into the body of the patient, the instrument has a supporting function and can be matched with a pedicle screw, a spinal connecting rod and the like for spinal correction to build a rib supporting orthopedic reduction frame, and the reduction frame can be adaptively bent according to the requirements of an affected part and the surgical requirements of the doctor in the operation.
