Background. Low back pain (LBP) continues to be a severe global healthy problem, and a lot of patients would undergo conservative or surgical treatments. However, the improving capacity of spinal load sharing during activities of daily living (ADLs) after interventions is largely unknown. The objective of this study was to quantitatively predict the improvement of spinal musculoskeletal loadings during level walking and stair climbing after two simulated interventions. Material and Methods. Twenty-six healthy adults and seven lumbar disc herniation patients performed level walking and stair climbing in sequence. The spinal movement was recorded using a motion capture system. The experimental data were applied to drive a musculoskeletal model to calculate all the lumbar joint resultant forces and muscle activities of seventeen main trunk muscle groups. Rehabilitation and reconstruction were selected as the representative of conservative and surgical treatment, respectively. The spinal load sharing after rehabilitation and reconstruction was predicted by replacing the patients’ spine rhythm with healthy subjects’ spine rhythm and altering the center of rotation at the L5S1 level, respectively. Results. During both level walking and stair climbing, the joint resultant forces of the lower lumbar intervertebral discs were predicted to reduce after the two simulated inventions. In addition, the maximum muscle activities of the most trunk muscle groups decreased after simulated rehabilitation and conversely increased after simulated reconstruction. Conclusion. The predictions revealed the different compensatory responses on the spinal load sharing after two simulated interventions, severing as guidance for making preoperative planning and rehabilitation planning.

The main purpose of this study was to investigate the compensatory response of the muscle activities of seventeen major muscle groups in the spinal region, intradiscal forces of the five lumbar motion segment units (MSUs), and facet forces acting on the ten lumbar facet joints in patients with lumbar disc herniation (LDH). Twenty-six healthy adults and seven LDH patients performed trunk flexion, ipsilateral picking up, and contralateral picking up in sequence. Eight optical markers were placed on the landmarks of the pelvis and spinal process. The coordinates of these markers were captured to drive a musculoskeletal model to calculate the muscle activities, intradiscal forces, and facet forces. The muscle activities of the majority of the seventeen major muscle groups were found increases in LDH patients. In addition, the LDH patients displayed larger compressive forces and anteroposterior forces on all the five lumbar MSUs and more lumbar facet inventions on most facet joints. These findings suggest that the LDH patients demonstrate compensatory increases in the most trunk muscle activities and all spinal loads. These negative compensatory responses increase the risk of the aggravation of disc herniation. Therefore, treatment should intervene as earlier as possible for the severe LDH patients.

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
