Description

  The present invention relates to a spinal deformity correction device for improving the daily life of a patient with posture deformation associated with a deformable spine.

  Patients with kyphosis associated with deformed spondylosis may develop disorders such as standing balance instability, difficulty walking, dysphagia, reflux esophagitis, etc. They are merged and often have compression fractures. The trunk orthosis used as a conservative therapy is said to have an effect of increasing the intra-abdominal pressure by supporting the waist and abdomen around the circumference and reducing the burden on the lower back muscles. The darmen corset, which is a soft brace, may cause abdominal pain when worn for a long time or during meals, or may be insufficiently fixed. Mold-type thoracolumbar rigid devices are created as devices that prevent deformation, correct, support weight, and suppress (fix) involuntary movements. However, the feeling of pressure, complications when wearing the devices, and skin irritation And does not bring comfort to the patient. Semi-rigid braces (rigid at the back and soft at the front) have insufficient frontal stability in patients with kyphosis. Metal frame type rigid braces, such as jet type rigid braces, are said to stabilize the spine by being pressed by the sternum, pubic bone, and thoracolumbar vertebra pads based on the principle of three-point fixation. On the other hand, stress concentrates only on the metal frame, and there is a problem that it is difficult for the elderly to adapt and difficult to continue wearing in terms of flexibility. In recent years, the development of materials used as braces has progressed, and scoliosis braces using a polycarbonate linear frame made of round bars have been developed (see, for example, Patent Document 1).
