Spinal fusion surgery is done by placing bone graft between the two vertebral bodies causing them to grow together into one long bone. The bone graft can either be obtained from the patient's own body (known as auto-graft) or from a cadaver (called as allograft) or a man-made graft of plastic or ceramic. Selection of right kind of procedure depends on the nature and location of the disease.
Lumbar Spine Fusion Surgery
Lumbar fusion surgery is done to make the patient relieve from low back pain radiating to hip and legs. There are many techniques to do a lumbar fusion surgery, but all the techniques involve using a bone graft between the two vertebrae to create fusion and thus stopping movement at that segment.
Various types of spinal fusion surgeries in India that Abyssinia can assist you with include:
- Posterolateral gutter fusion involves accessing the spine through the back
- Posterior lumbar inter-body fusion (PLIF/TLIF) involves accessing the spine through back while the patient lies on his stomach. The procedure entails removing the disc between two vertebrae and inserting the bone graft in the space.
- Anterior lumbar inter-body fusion (ALIF) - same as TLIF or PLIF except that the spine is accessed from the front. The technique remains the same.
- Anterior/posterior spinal fusion spine is accessed from back and front both
Minimally invasive techniques involve fusions to be done with smaller incisions.
Bone Grafting
Any spinal fusion procedure requires bone grafts to help in fusion. Bone grafts stimulate bone healing and help vertebrae to fuse into a solid bone or even act as structural support in case of bigger bone grafts. Grafts from one's own body is called auto graft. Another kind of graft is called cadaver bone graft is typically acquired through a bone bank.
Immobilization with braces, plates, rods and screws are used to stabilize the bone and for internal fixation which speeds up the healing process.
Multiple level Spinal Fusion Surgery
Lumbar spinal fusion surgery is most effective in conditions involving only one vertebral segment because the patient does not feel any limitation in the motion after fusion at one level. In case necessary, fusing two levels is a reasonable option to treat pain. However, spinal fusion for more than two levels can cause too much stress across the remaining spinal joints causing pain at other levels. Only in rare cases three or more level fusion is advised such as scoliosis and lumbar deformity.
Cervical Spine fusion surgery
This involves fusing cervical spinal bones in case of injuries to stabilize the neck and to prevent vertebral fracture that damage the spinal cord and cause paralysis. Cervical spine fusion surgery is also done to treat spinal stenosis, herniated disc, infection, tumour or other spinal deformities.
