Spinal stenosis can be treated with cryo-plasma ablation. Hypothermic plasma ablation can cut the proliferated tissues in the spinal canal to achieve decompression. 1. The principle of low-temperature plasma ablation is to cut, ablate and hemostasis the hyperplastic tissues with low temperature through the low-temperature ablation effect of plasma, which has a shallow effect on the tissues and the depth of the damage, so the inflammatory reaction after the operation is less severe, which can greatly reduce the pain of the patients and shorten the recovery period. 2. The causes of spinal stenosis are many, and the most common causes are osteophytes caused by degenerative diseases, hypertrophy of the ligamentum flavum, and narrowing of the lateral fossa, which leads to spinal stenosis. Symptoms such as pain and numbness occur when the effective space of the spinal canal is compressed. Using low-temperature plasma ablation, the hyperplastic ligaments and other tissues can be cut, thereby reducing the pressure on the spinal canal. Spinal stenosis can be treated with cryo-plasma ablation, but patients should take their doctor’s advice on the most appropriate procedure.
