Background: Acute lumbar disc herniation can occur in every lumbar intervertebral disc space and in multiple levels simultaneously. In the cases of 2 levels adjacent lumbar disc herniations of severe unilateral radiculopathic leg pain caused by compression of the nerve roots, respectively, multiple incision or long incision is generally needed for simultaneous removal of disc fragment in 2 levels.
Objectives: We proposed the minimally invasive one portal skin incision endoscopic discectomy is effective and safe method to treat 2 levels adjacent lumbar disc herniation.
Materials And Methods: We have experimented total 8 cases of 2 levels adjacent lumbar disc herniation having unilateral radiculopathic pain respectively. All cases are 2 levels adjacent lumbar disc herniation. We have tried a percutaneous endoscopic transforaminal approach through minimal one portal skin incision and remove the two herniated disc materials in the adjacent levels.
Results: The L2-L3 level was involved in 2 patients, L3-L4 level in 6 patients, while the L4-L5 level was involved in 7 patients, L5-S1 level in 1 patient. The mean follow-up was 18.5 months. The mean visual analogue score (VAS) of the patients prior to surgery was 7.75, and the mean postoperative VAS was 2.375. According to Macnab's criteria, 3 patients had excellent results, 4 patients had good results, 1 patient had fair results, and no patient had a poor result; satisfactory results were obtained in 87.5% of the cases.
Conclusion: The percutaneous endoscopic transforaminal approach through 1 skin portal incision could be effective surgical method in unilateral adjacent 2 levels lumbar disc herniation.

Purpose Of Review: Low back pain (LBP) is considered an important issue of public health, with annual prevalence estimations almost achieving 60% of the worldwide population. Available treatments have a limited impact on this condition, although they allow to alleviate pain and recover the patient's quality of life. This review aims to go deeper on the understanding of this condition, providing an updated, brief, and concise whole picture of this common musculoskeletal problem.

The aim of this study was to evaluate the effectiveness of Fascial Manipulation in patients with disc herniations of the lumbar spine confirmed by magnetic resonance imaging. This study included 69 patients with intervertebral disc damage of the lumbar spine, as confirmed by magnetic resonance imaging. Patients were divided into two groups: a study group and a control group.

In this study, we explored the impact of different biomechanical loadings on lumbar spine motion segments, particularly concerning intervertebral disc degeneration (IVDD). We aimed to uncover the cellular milieu and mechanisms driving ossification in the nucleus pulposus (NP) during IVDD, a process whose underlying mechanisms have remained elusive. The study involved the examination of fresh NP tissue from the L3-S1 segment of five individuals, either with IVDD or healthy.

Purpose: This study aimed to compare the incidence of radiological adjacent segment disease (R-ASD) at L3/4 between patients with L4/5 degenerative spondylolisthesis (DS) who underwent L4/5 posterior lumbar interbody fusion (PLIF) and those who underwent microscopic bilateral decompression via a unilateral approach (MBDU) at L4/5. Our ultimate goal was to distinguish the course of natural lumbar degeneration from fusion-related degeneration while eliminating L4/5 decompression as a confounder.
Methods: Ninety patients with L4/5 DS who underwent L4/5 PLIF (n = 53) or MBDU (n = 37) and were followed for at least 5 years were retrospectively analyzed.

Unlabelled: Due to the increasing number of people working at computers in professional settings, the incidence of lumbar disc herniation is increasing.
Background/objectives: The early diagnosis and treatment of lumbar disc herniation is much more likely to yield favorable results, allowing the hernia to be treated before it develops further. The aim of this study was to classify lumbar disc herniations in a computer-aided, fully automated manner using magnetic resonance images (MRIs).
