Benefits from minimally invasive back surgery

A minimally invasive spinal fusion back surgery results in less blood loss, less post-operative pain, smaller incisions, a shorter hospital stay and faster recovery and return to work, reports Science Daily. Rather than cutting through para-spinal (back) muscles, the surgeon spreads and dilates the muscles to obtain access to the lumbar (lower back) spine. One such operation is called a minimally invasive transforaminal lumbar inter-body fusion (MIS TLIF).

It's a complex procedure with a steep learning curve, said Loyola University Medical Centre spine surgeon Dr Beejal Amin, who has given talks about the procedure around the country.

Amin learned the procedure while completing a fellowship in minimally invasive and complex spine surgery at the University of California at San Francisco Medical Centre. Patient William Hoecker is among Amin's patients who have greatly benefited from the procedure. Hoecker suffered debilitating leg pain and numbness due to degenerative spondylolisthesis and spinal stenosis. One vertebra had slipped forward over the vertebra below it, pinching the nerve root and causing pain in the left leg. For Hoecker, walking just 25 feet was so painful he would have to sit or lie down. He was unable to drive for more than 20 minutes. "I was stuck in my house," he said.

Amin fused the L4 and L5 vertebrae in Hoecker's lower back. First, he decompressed the spinal nerve roots. Next, he removed the degenerated disc between the two vertebrae. Then an implant filled with bone graft was placed in the empty disc space between the vertebrae. Amin implanted rods and screws to hold the vertebrae together. As the bone graft healed, it fused the two vertebrae together, resulting in a single bone.

The surgery dramatically improved Hoecker's quality of life. He now can walk or drive without limitations.
