Abstract

Aim

Minimally invasive approaches to posterior lumbar surgery are available today that can enhance patient comfort by greatly reducing tissue damage and offer better clinical results. However, such methods have not yet gained widespread popularity despite their significant advantages. This study compares the Wiltse method and the classical method of lumbar surgery based a cohort, clinical study of 57 patients. The patients all had degenerative lumbar spinal stenosis and/or spondylolisthesis and had developed multifidus muscular atrophy.

Materials and methods

We enrolled 57 patients admitted to our clinic between April 2012 and September 2013 with a diagnosis of degenerative lumbar spinal stenosis and/or spondylolisthesis. These were treated with the classic posterior approach (n=26) or the Wiltse method (n=31).

Findings

In the classical method group, the ratio of female to male patients was 20/6 and the mean age was 58.19±10.17 years. A comparison of preoperative and postoperative multifidus muscle cross-sectional measurements (average of right and left) revealed a 36.09% atrophy level in the classical method group and a 26.34% atrophy level in the Wiltse group (p<0.01). However, atrophy development was 18.82% higher in the classical method group (p<0.05) relative to the Wiltse group.

Conclusion

The Wiltse method is less invasive and causes less tissue damage. It reduces the change of hemorrhage and multifidus muscles and offers a shorter duration of hospitalization with less pain.
