Abstract  Introduction:

We developed the method of cervical spinal cord decompression through durotomy followed by duroplasty and analyzed its efficacy.


To develop a tactic of decompression durotomy and duroplasty for the treatment of severe spinal cord injury(SCI) with extensive edema of the spinal cord and without intramedullary hematoma, and to demonstrate the effectiveness of this method.


From October 2016 to January 2018, 17 decompression operations were performed in the cervical spine in patients with SCI. Decompression laminectomy was done without durotomy in the first group of patients. In the second group, duroplasty of the spinal cord was performed after decompression durotomy. A total of 17 patients, 16 males (94%) and 1 female (6%), were operated on (ages from 32 to 66 years). The patients were divided into two groups: a control group and an experimental group. We used the ASIA scale for assessing the patients. The mean follow up time is 12 months (8−24 months).


The first group, i.e., the control group consisted of 10 patients who underwent decompression laminectomy without durotomy. The second group, i.e., the experimental group consisted of 7 patients who underwent durotomy followed by duroplasty. In this group, the positive dynamics were observed in 6 patients. Out of 2 patients with ASIA grade “A”, one showed improvement to ASIA grade “C”, and one improved to ASIA “D”. Two patients with ASIA grade “B” showed recovery to ASIA “D”. Two patients with ASIA grade “C” improved to grade “D” while one patient showed no change from ASIA “C”. Durotomy and duroplasty was effective in the experimental group.


The performance of durotomy and duroplasty is an efficient method for the full-scale decompression of the spinal cord and the prevention of edema. This method aims at decreasing intraspinal pressure, as well as preventing ischemia and apoptosis, which is possible for the prevention and treatment of the spinal cord compartment syndrome or spinal cord intramedullary hypertension.
