Indicated for patients experiencing continued or worsened pain (or function) following spinal surgery, revision spine surgery may be used to repair problems from earlier surgical interventions. Revision spine surgery can help to reduce pain and resume normal activities in cases of post-surgical complication, unsuccessful surgeries or instances where scar tissue has formed around the nerves.
Patients with progressive deformities, or who develop new or worsening symptoms despite surgery, require careful evaluation. Preoperative planning is paramount, and post-surgical rehabilitation to strengthen the affected areas may be required. Non-surgical intervention is preferred when possible. Revision surgery may involve a minimally invasive approach using small incisions in order to minimize damage to surrounding muscles and tissues.
In cases such as pseudoarthrosis, where the bone fails to heal properly following fusion surgery, patients may develop progressive deformities above and below the surgical site which necessitate a second surgery. Common conditions treated by revision surgery include: FBSS (failed back surgery syndrome); flatback syndrome; recurring disc herniations; ADS (adjacent segment disease); pseudoarthroses; radiculopathy or stenosis, causing problems with leg mobility associated with chronic nerve compression; infection in the spine or around instrumentation; post-fusion arthritis; or problems with implanted hardware.
Revision surgery may include an extension of a previous fusion, the placement of additional instrumentation, osteotomies (corrective fracturing of the affected bones), removal of implants, irrigation and removal of infected tissues, or decompression to relieve pinched nerves (stenosis).
