BACKGROUND: Risk factors for incidental durotomies are good documented claimed from some authors the degree of invasiveness as a direct risk factor on this serious complication. We compared the rate of incidental durotomies and its dependence from the degree of invasiveness.
METHODS: The German Spine Registry could document 6016 surgeries for lumbar spinal canal stenosis, n= 2539 microsurgical decompression and n= 2371 open decompression with stabilization.
RESULTS: Both groups were identical concerning age and sex of patients: mean age 77,1 ± 1,60, female 58%, male 32%. There were 410 incidental durotomies, group 1 209 (8,23%), group 2 201 (8,47%). This difference is statistically not relevant (p=0,75). A surgical therapy is documented in 345 (84%) cases: suture with/ without fibrin glue: group 1= 162 and group 2= 183. 59 patients had a persistent fistula that needed treatment with a lumbar drain: group 1 n=30 and group 2 =29.
CONCLUSIONS: The groups decompression vs. decompression plus fusion are statistically comparable. Although the stabilization with instrumentation is a more invasive procedure with longer operation times, more trauma tissue and blood loss in comparison with microsurgical decompression no difference in the rate of incidental durotomies was found.
