New Minimally Invasive Fusion Techniques
New Minimally Invasive Fusion Techniques
- 1Oblique Lateral Interbody Fusion (OLIF)
An OLIF (sometimes called OLLIF) is a newer lumbar surgery and is performed through the side. It minimizes cutting to muscles and uses a single port to access the disc space, fill it with bone material and then fuse the relevant vertebra together. This restores correct spine height, position and curvature, and fixes pain by decompressing nerves and restricting movement.
In Endoscopic OLIF surgery a small surgical port is used to allow access of the ‘corridor’ between the psoas muscle and anterior vasculature. This minimally invasive approach preserves the psoas muscle, avoids interaction with nerve structures, and patients benefit from less bleeding, less pain and a faster recovery. The number of established surgeons beginning to offer MIS OLIF is rapidly increasing by around 10% every year.

- 2Transforaminal Lumbar Interbody Fusion (TLIF)
A TLIF surgery is performed through the back. The spine is accessed through the foramen or opening that allows the nerves to exit the spinal cord. The damaged disc is partially removed so that a spacer can be inserted into the disc space. A bone graft is then inserted that envelopes the spacer to create a stable disc that results in permanent fusion and stability of the spine.
Endoscopic (keyhole) TLIF is a new minimally-invasive approach that uses smaller keyhole incisions of around 10-millimeters to access the spine. Without the need to strip muscle out of the bone, patients also benefit from less pain, less blood loss and can return to normal life in less time.
