About the Therapy
A procedure called a spinal fusion can be used to surgically treat degenerative disc disease in the spine. Using bone harvested from the person’s own hip (autograft) and instrumentation such as rods and screws, this procedure fuses two or more adjacent vertebrae. This is done to stabilise the spine and provide pain relief.
A spinal fusion is the uniting of two bony segments, whether a fracture or a vertebral joint. Instrumentation featuring rods and screws acts as an “internal cast” to stabilise the vertebrae until the fusion, or bony re-growth, can occur.
The various types of spinal fusion refer both to the affected area of the spine and the area of the spine being fused.
Anterior cervical discectomy and fusion is neck surgery that involves approaching the spine through an incision in the front of the neck. The affected disc is removed and replaced with bone from the individual’s hip. In some cases, the surgeon will implant a small metal plate to stabilise the spine while it heals.
Anterior lumbar interbody fusion (ALIF) is back surgery that involves approaching the spine through an incision in the abdomen. A portion of the affected disc space is removed from the spine and replaced with an implant. Titanium or stainless steel screws and rods may be inserted into the back of the spine to supplement the stability of the entire construct.
Posterior lumbar interbody fusion (PLIF) is a type of back surgery that involves approaching the spine from the back (posterior) of the body. Bone graft material is then placed between two adjacent vertebrae (interbody) to promote bone growth that joins together the two structures (fusion). The bone graft material acts as a bridge, or scaffold, on which new bone can grow. The ultimate goal of the procedure is to restore spinal stability.
Today, a PLIF may be performed using minimally invasive spine surgery. This procedure allows the surgeon to use small incisions and gently separate the muscles surrounding the spine rather than cutting them. Traditional open spine surgery involves cutting or stripping the muscles from the spine. A minimally invasive approach preserves the surrounding muscular and vascular function and minimises scarring.1,2
Transforaminal lumbar interbody fusion (TLIF) is a form of back surgery in which the lumbar spine is approached through an incision in the back. The name of the procedure is derived from: transforaminal (through the foramen), lumbar (lower back), interbody (implants or bone graft placed between two vertebral bodies) and fusion (spinal stabilisation).
