Lumbar spondylolisthesis is one of the common degenerative diseases of the lumbar spine in middle-aged and elderly people. Patients with moderate to severe lumbar spondylolisthesis with poor conservative treatment often require surgical treatment. Traditional surgical methods are traumatic, bleeding, and risky, requiring long-term bed rest after surgery. Inability to get up early, the incidence of complications is high, and it is difficult for patients to accept, especially for elderly patients, it is relatively contraindication to surgery. With subforaminal local anesthesia, surgical procedures such as decompression, lysis, and fusion can be completely achieved.
