MIS TLIF

MIS TLIF stands for Minimally Invasive Transforaminal Lumbar Interbody Fusion. It is a surgical procedure used to treat certain spinal conditions, typically involving the lumbar (lower) region of the spine. This minimally invasive approach aims to achieve spinal fusion while causing less disruption to surrounding tissues compared to traditional open surgery.

Minimally Invasive Approach: As the name suggests, MIS TLIF utilizes a minimally invasive surgical technique. This involves making small incisions, usually less than an inch in size, through which specialized instruments and a camera (endoscope) are inserted. This approach is designed to minimize damage to muscles and other soft tissues, leading to potentially faster recovery times and reduced postoperative pain.

Transforaminal Lumbar Interbody Fusion (TLIF): TLIF is a type of spinal fusion procedure that involves accessing the spine through the intervertebral foramen, the opening on the side of the spinal column through which spinal nerve roots exit. In TLIF, a portion of the lamina (a bony arch on the back of the vertebra) may be removed to access the intervertebral disc. The disc is then partially or completely removed, and a bone graft or a cage filled with bone graft material is inserted into the disc space to promote fusion between the adjacent vertebrae.

Pedicle Screws and Rods: Pedicle screws are often used to stabilize the spine during TLIF. These screws are inserted into the pedicles of the vertebrae, and rods are connected to them to provide additional support and help maintain proper spinal alignment.

Bone Graft: The bone graft serves as a scaffold for new bone growth and fusion. It can be sourced from the patient's own body (autograft) or from a donor (allograft). Alternatively, synthetic bone graft substitutes may be used.

Facet Joint Removal: In some cases, part of the facet joint (the joints between the vertebrae) may be removed to create more space for nerve roots and to facilitate the fusion process.
