Fusion serves as a method to stabilise the spine by uniting two vertebrae. In contemporary practice, the standard for achieving lumbar fusion is Transforaminal Lumbar Interbody Fusion (TLIF), performed from the back. The transforaminal approach accesses the disc through the space between the vertebrae.
In the conventional technique, the spine is approached posteriorly, with the paraspinal muscles separated and retracted from their attachment. This is followed by a partial or complete removal of facets (small joints in the back), discectomy, and the insertion of a cage (artificial spacer and bone). Importantly, minimal retraction of the nerve root and dural sac is ensured.
When performing minimally invasive surgery, spine specialist rely on a profound understanding of anatomy and to utilise radiographic imaging to address spinal conditions without causing undue injury to surrounding soft tissues. This technique allows for gently separating the muscles surrounding the spine rather than cutting through them. The potential benefits include smaller scars, reduced pain, and a quicker recovery.
