Description

Lumbar curvature and pelvic correction instrument

Technical Field

The invention relates to the field of bone correction equipment, in particular to a lumbar curvature and pelvis correction instrument.

Background technique

With the change of modern lifestyle, human spinal health problems are becoming increasingly prominent, especially the problems of lumbar curvature and pelvic tilt. Lumbar curvature refers to the lumbar lordosis exceeding the normal range, resulting in uneven force on the spine, placing a huge burden on the surrounding muscles and intervertebral discs, and easily causing a series of problems such as lumbar disc degeneration, spinal instability, spinal canal stenosis, and interspinous ligament injury. Pelvic tilt is caused by the sacrum tilting backwards, resulting in unbalanced spinal force transmission, muscle fatigue, and excessive stress on local intervertebral discs, which may cause autonomic dysfunction.

There are many factors that cause excessive lumbar curvature and pelvic anterior tilt, including but not limited to children's excessive abdominal extension, sleeping habits of lying on the table, and excessive abdominal weight in pregnant women and obese people. These problems not only affect the individual's quality of life, but may also lead to serious health risks, such as lumbar pain, nerve compression, etc.

At present, the treatment methods for these problems are mainly to improve posture and orthopedic treatment, but the efficacy is not stable enough and it is difficult to meet the needs of the majority of patients. Therefore, it is of great significance to develop an instrument that can effectively treat or prevent lumbar curvature and pelvic anterior tilt, which can not only provide patients with more effective treatment options, but also provide the medical community with new treatment ideas and methods.
