Recurrence of lumbar disk herniation after microdiscectomy: a two-center retrospective analysis of 1214 cases and identification of risk factors.

Background/aim: To present the incidence of recurrent lumbar disc herniation (RLDH) and to identify radiological and patient-related risk factors that lead to recurrence after lumbar disc herniation (LDH) treatment with microdiscectomy.

Materials And Methods: Between January 2013 and December 2021, 1214 patients who had undergone microdiscectomy for LDH were included in this retrospective study. Patients were divided into two groups, the recurrent group and the non-recurrent group, and their demographic, clinical and radiologic characteristics were recorded.

COMPARISON TACHOCOMB WITH SURGIWRAP, SURGICEL AND LYODURA IN EPIDURAL FIBROSIS: AN EXPERIMENTAL RAT MODEL.

Objectives: We designed this study to evaluate the effect of TachoComb and to compare it with SurgiWrap, Surgicel, and Lyodura in an experimental rat model for epidural fibrosis (EF).

Methods: This prospective and experimental rat model study was performed at Dicle University, School of Medicine, Department of Neurosurgery, in Diyarbakir, Turkey, between January 2005 and June 2005, using 50 Sprague Dawley rats (30 female and 20 male) with a mean weight of 290 g. The rats were divided into five groups: TachoComb, Surgicel, SurgiWrap, Lyodura, and control.
