There are many types of lumbar spine surgery, and the time to fly will vary depending on the severity of the underlying disease, the surgical treatment plan taken, and the post-operative recovery. If the vertebroplasty surgery is done for elderly people with lumbar compression fractures, you can fly normally 3-5 days after this surgery. However, if the lumbar spine is fractured or the shoulder disc is herniated or the spinal canal is narrowed, it should take 2-3 months after the nail rod internal fixation surgery before you can slowly fly. Because of the nature of the process of flying is a long time sitting can not move, most of them are in a fixed position, the strain on the lumbar spine is relatively large. Especially in the early post-operative period, most lumbar vertebrae cannot withstand this strain, which can easily lead to increased pain in the back. And the two types of surgery mentioned above, the first is the fracture healing is not solid, the second is the stability of the vertebral body is not completely restored or implant fusion is not particularly firm, so do not sit in the airplane too early.
