Anterior Lumbar Interbody Fusion

Anterior lumbar interbody fusion (ALIF) is a surgical procedure to correct the spinal problems from the front of the vertebral body by removing disc or other bone material from in between two adjacent lumbar vertebrae. The surgery can be implemented either as an open surgery or minimally invasive techniques.

Anterior lumbar interbody fusion (ALIF) is a spinal surgery that involves removal of all or part of a herniated disc from in between two contiguous vertebrae (interbody) from the front of the vertebral body in the lower back region (lumbar spine) and fusing or joining the two vertebrae together so that they heal into a single, solid bone. A bone graft or a substitute bone graft can be used on both sides of the remaining disc space of the vertebrae.

The graft material binds the two vertebrae together and promotes bone healing, facilitates the fusion and helps to preserve the normal disc height as the body heals. Along with the vertebral bone, the bone graft also grows and stabilizes the spine. An ‘internal cast’ made up of certain instruments such as rods, screws, plates, cages, hooks and wires can be used to support the vertebral structure during the healing process.
