Screen_shot_2013-12-09_at_10.20.29_AMDr. Donald S. Corenman recently completed a study on the effects of failed minimally invasive spine surgery on lumbar spinal fusion outcomes. The study hypothesized: patients who suffered failed minimally invasive spine surgery (MISS) would incur inferior lumbar spinal fusion compared with patients who were not treated with prior MISS.

Minimally invasive spine surgery, also referred to as less invasive spine surgery (LISS), is a surgical procedure that creates access to the spine through small incisions. This surgical procedure was designed to limit damage to the surrounding structures and muscles in the spine.

Spinal fusion is a common procedure for patients that have undergone minimally invasive spine surgery. Spinal fusion is used to treat spinal deformities such as scoliosis and kyphosis. The procedure joins two or more vertebrae together using supplemental bone tissue. By immobilizing the fused vertebrate, there is a decrease in the level of back pain.

47 qualified patients were split into two groups – a prior LISS surgery group (PSG) and a non-prior LISS surgery group (nPSG) – through the use of questionnaires, the study evaluated: patient satisfaction, return to work rates, peri-operative complications, success of the fusion rate and rate of revision surgery. Limited by size, the study found that patients who experienced failed LISS prior to undergoing spinal fusion did not suffer inferior fusion outcomes when compared to patients who did not undergo prior LISS.
