Lumbar indirect decompression is used to treat degenerative arthritic conditions of the lumbar spine. Indirect decompression in spinal surgery means decompression of spinal nerve tissues, such as spinal cord and nerve, without resecting the compressing tissue. Indirect spinal decompression procedures largely can be divided into segmental procedures and global spinal alignment procedures. Segmental procedures are mainly performed by the distraction between two vertebrae, which lead to the opening of the neural foramen and increases the epidural space. This can be accomplished with the insertion of a small titanium device 1 1/2 inches deep to skin to prevent the spinal nerves from being irritated causing pain.
