Background: Because the neurological presentation of spinal epidural hematomas (SEH) is often not specific, they may be misdiagnosed as acute lumbar disk herniations. Here, we present a case in which a traumatic disc extrusion mimicked an epidural hematoma and reviewed the appropriate literature. Case Description: A 27-year-old male sustained a high-energy fall. The lumbar MRI scan showed a L4-S1 ventral medium/high signal intensity mass on the T1- and high signal intensity lesion on T2-weighted images; the original diagnosis was spinal epidural hematoma. However, at surgery, consisting of a left L4 and L5 hemilaminectomy with L4-L5 and L5-S1 laminotomy, an extruded lumbar disc was encountered at the L4-L5 level and removed; no additional pathology or SEH was found at either level. Conclusion: On MR, SEH may mimic acute lumbar disk herniations. Depending on the clinical symptoms/signs, surgical intervention will both correctly confirm the diagnosis and relieve neural compression.

Objective To assess the composition of lumbar multifidus muscle, in patients with unilateral lumbar disc herniation causing nerve compression, using quantitative and qualitative magnetic resonance imaging (MRI) measurement methods. Methods Two radiologists retrospectively measured MRI signal intensity of the multifidus muscle, as high intensity represents more fat, and visually graded the fat content using a 5-point grading system in patients with unilateral subarticular lumbar disc herniation. Findings from the herniated and contralateral sides were compared. The association between fat content and severity of nerve compression and symptom duration were also evaluated. Results Ninety patients (aged 24–70 years) were included. Signal intensity of the affected multifidus muscle was significantly higher versus the contralateral muscle for quantitative measurements and qualitative scoring for both investigators. Significant correlations were observed between the severity of nerve compression and symptom duration and the degree of fat content in the affected multifidus muscle. Conclusions Higher fat composition was observed in the multifidus muscle ipsilateral to the lumbar disc herniation versus the contralateral side. Straightforward visual grading of muscle composition regarding fat infiltration appeared to be as useful as quantitative measurement.

Common Procedure

Summary Lumbar disc herniation (LDH) is the most common pathology in young people, as well as people of active age. Despite sophisticated and new minimally invasive surgical techniques and approaches, reoperations for recurrent lumbar disc herniation (rLDH) could not be avoided. LDH recurrence rates, reported in different studies, range from 5 to 25%. The purpose of this study was to estimate the recurrence rates of LDH after standard discectomy (SD) and microdiscectomy (MD), and compare them to those reported in the literature. Retrospectively, operative reports for the period 2012-2017 were reviewed on LDH surgeries performed at the Neurosurgery Clinic of Dr Georgi Stranski University Hospital in Pleven. Five hundred eighty-nine single-level lumbar discectomies were performed by one neurosurgeon. The diagnoses of recurrent disc herniation were based on the development of new symptoms and magnetic resonance/computed tomography (MRI/CT) images showing compatible lesions in the same lumbar level as the primary lumbar discectomies. The recurrence rate was determined by using chi-square tests and directional measures. SD was the most common procedure (498 patients) followed by MD (91 patients). The cumulative reoperation rate for rLDH was 7.5%. From a total number of reoperations, 26 were males (59.1%) and 18 were females (40.9%). Reoperation rates were 7.6% and 6.6% after SD and MD respectively. The recurrence rate was not significantly higher for SD. Our recurrence rate was 7.5%, which makes it comparable with the rates of 5-25% reported in the literature.

Introduction: Surgical wound infection in developing coutries is about 3%. Antibiotics prophylaxis may help to reduce the surgical site infection. The objective of this study was to evaluate the efficacy of antibiotics prophylaxis in patients with lumbar disc herniation who were treated with lumbar discectomy at Hue University hospital. Materials and Methods: A prospective study was conducted at Hue University hospital from March 2015 to May 2018 on 54 patients with lumbar disc herniation who were used antibiotics prophylaxis when undergoing discectomy. Results: The infection rate in our study was 0%. Antibiotics prophylaxis reduced the length of hospitalization as well as the medical cost. Conclusion: Antibiotics prophylaxis was effective in preventing surgical site infection despite the fact that the condition of operating rooms did not meet the standard rules. Key words: prophylaxis antibiotics, lumbar disc herniation
