The objective of this study is to know about the frequency of incidental durotomy during surgery for degenerative lumbar spine disease.
It was a Descriptive cross sectional study conducted on the admitted patients of degenerative Lumbar spinal disease in the Department of Neurosurgery, Lady Reading Hospital, Peshawar, in six months duration. Total of 186 patients were enrolled in the study. Surgery was performed in the form of laminectomy and fenestration under general anesthesia by single expert neurosurgeon having a minimum of 5 years of experience. All the patients were properly looked for incidental durotomy during surgery and was properly documented.
In this study 186 patients were observed in 6 months duration. Age range was
20 – 60 years with mean age y of 39.91 years +- 10.584 of standard deviation . Out of 186 patients about 106 patients were male and 80 patients were female with male to female ratio of 1.33: 1. Incidental durotomy was found in 8 cases (4.30%).
