Durotomy (Incidental dural tears or ID) is a very rarely occurring disorder when decompressive surgery (spinal surgery) of the patients takes place. This disorder has severe effects on patients. During different surgeries of the spinal cord, the chances of this durotomy vary greatly. Objective: The main objective of this research work is to evaluate the main reasons for the incidence of this durotomy disease. During different surgeries of the spinal cord surgeries (decompressive and compressive) within the different regions, many factors play their role in the initiation of this durotomy disease. It is the target of this work to find the initiation factors of the disease so that effective methods of treatment can also find out. Methods: It was a retrospective study with a statistical approach. This study was conducted in Neurosurgery unit, Mardan medical complex / Bacha khan medical college, Mardan for the Duration of one year August 2020 to July 2021. To proceed with this study, 30 patients were selected with posterolateral and posterior compressive and decompressive surgeries within the different regions of the spinal cord. The patients were randomly selected from December 2020 to December 2021. Results: The incidence of this durotomy disease was investigated within all groups and the probability of this disease was only 12.65%. The occurrence of this disease also depends upon the type of surgery. Patients suffering from spinal trauma, stenosis of the spinal, different tumors, and vertebral disc herniation had exaggerating role in the incidence of durotomy in patients having some spinal surgery. Conclusion: The durotomy disease should be considered a serious issue with a number of other complications. For the treatment of this disease, prevention is the best method and to know about the complications is important because all of the factors involved in the incidence of durotomy should be considered while performing any kind of surgery
