Abstract
Minimally invasive lumbar spine fusion surgeries are becoming more popular, due to their more tolerable post-operative pain and faster recovery. Our study included 75 patients operated upon by single level posterolateral fixation distributed into two groups, the miniopen (30 patients) and classic approach (45 patients). The miniopen approach was found to be associated with significantly less postoperative pain on the VAS, particularly on the third and seventh post-operative days (p=<0.001). The post-operative hospital stay was also significantly shorter in the miniopen group. It was also found to be equally safe and effective. The addition of interbody fusion to surgery was not found to statistically affect the immediate post-operative outcome. The miniopen approach can be very useful for lumbar spine fusion especially in single level less complicated surgeries, which offer the maximal benefit from this minimally invasive approach
