Also known as extreme lateral (XLIF) or direct lateral interbody fusion (DLIF), LLIF is a procedure that accesses the spine from incisions created on the side of the body. It is performed to provide relief from symptoms due to conditions such as:
The focus of a surgical treatment is to drastically improve quality of life. Back doctor Dr. LaRocca may propose back surgery in the event of noticeable tiredness, extreme pains or when all other treatment options have been implemented.
During the Procedure
During the procedure, Dr. LaRocca may approach the spine through an incision in the flank, the space on the side of the body between the ribs and the hip. In doing so, he avoids separating back muscles, cutting bone, moving major blood vessels, or moving spinal nerves as opposed to approaches such as:
A surgical instrument known as a tubular retractor is then inserted through the skin and onto the spinal column to hold the muscles open.
Once there is a clear view of the spine, the affected spinal disc material is removed and a spacer known as a cage containing bone graft material is placed in the empty space to encourage the two vertebrae to heal and fuse together. The bone graft material is rarely taken from the hip but may also be donated from a cadaver or consist of various biologically active materials that promote bone growth. Screws made of titanium may then be inserted to hold the cage in place.
There are a few advantages to this approach over other approaches, including:
Dr. LaRocca can help patients determine what approach is best based on the individualized needs of patients.
After the Procedure
Patients may be allowed to leave the day of surgery or the day after due to the minimally invasive nature of the procedure. Patients may return to normal activity within four to six weeks.
