Lumbar curvature change caused by lumbar muscle tension is one of the most important causes of low back pain. This process is often a rather long chronic course, and it is also a common chronic degenerative disease in spine surgery. Most people over 65 years old undergoing spinal surgery are caused by this disease.

Usually, in the degenerative changes of the lumbar spine, the intervertebral disc deforms first. After the degeneration of the intervertebral disc, the originally normal lumbar spine curvature, structure and position change, making the edge of the lumbar spine stressed, and the middle stress is small. Where there's a lot of stress, there's an osteophyte that ADAPTS to the new structure, and that osteophyte is what we call a bone spur. Although such bone hyperplasia will enhance the stability of the lumbar spine, it will also cause changes in lumbar curvature, muscle imbalance, spinal stenosis, so the degeneration of the intervertebral disc is often the starting link of spinal degeneration.

3D printed lumbar pillow

When severe pain and clinical symptoms occur, lumbar curvature and skeletal structural degeneration have progressed to a more serious stage, and conservative treatment is difficult to obtain the ideal treatment effect. At this time, surgical treatment is needed to relieve the compression of the spinal cord and nerve roots, improve pain and other clinical symptoms.

By means of 3D scanning, computer design and 3D printing, the 3D printed lumbar pillow developed by the team of Academician Dai Kiburong and Professor Wang Jinwu of Shanghai Ninth Institute can relieve the tension of lumbar muscles and help improve the curvature of the lumbar spine. Generally, different curvaments can be adjusted and replaced individually according to the situation for about 3 months, and good clinical efficacy has been achieved
