Minimally invasive tubular decompression versus traditional open surgery for lumbar spinal stenosis: a systematic review and meta-analysis.

Five studies ( n = 1327) suggested a lower risk of dural tears in the MI group, although the finding did not reach statistical significance (OR 0.53, 95% CI [0.28; 1.03], p = 0.0604; Fig. 2 B) with minimal heterogeneity (I 2 = 5.4%).

The relatively small number of studies also restricts statistical power, limiting the ability to detect smaller yet clinically important differences – a limitation exemplified by the near-significant findings observed for dural tear incidence.
