Background: Low back pain (LBP) is one of the most common spine diseases and represents the most frequent cause of absence from work in developed countries. Approximately 40% of chronic LBP is related to discogenic origin. The goal of the study is producing a review of literature to describe analytically the techniques of intradiscal injections.
Methods: PubMed database was searched for clinical studies with the different key terms: "intradiscal", "injection", "steroid" "procedures", "techniques", "CT", "MRI", "fluoroscopy", "fluoroscopic", "guidance", "ozone", "ultrasound", "images". Only studies written in English, French, or Italian in which the intradiscal injection represents the main procedure for the low back discopathy treatment on humans were considered. We excluded the articles that do not mention this procedure; those which indicated that the intradiscal injection had happened accidentally during other treatments; those reporting the patient's pain was determined by other causes than the discopathy (facet joint syndrome, tumor, spondylodiscitis).
Results: Thirty-one articles dated from 1969 to 2018 met the criteria. The examined population was 6843 subjects, 52.3% male and 47.7% female, with a mean age of 45.9±10.1 years. The techniques are highly variable in terms of procedure: different operators, needle guidance, injection sites, drugs, tilt angle of the needle).
Conclusion: The efficacy and the safety of the intradiscal procedures are not easily comparable due to different types of studies and their limited number. Further studies are needed to standardize the intradiscal injection technique/procedure to improve safety, repeatability and effectiveness, and last but not least to reduce peri- and postoperative care and health-care costs.

Introduction: Ischaemic stroke, primarily caused by thromboembolic events, typically arises as a consequence of underlying vascular or cardiac pathology. Non-thrombotic embolic strokes, although rare, are increasingly seen in interventional and intravascular procedures. Oxygen-ozone therapy (OOT) is one of the popular treatments for lumbar disc herniation, providing pain relief.

Article Synopsis
- Recent research highlights the potential of biologic treatments like mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) for relieving low back pain by promoting healing in intervertebral discs.
- A systematic review and meta-analysis evaluated the effectiveness of MSC and PRP injections for chronic low back and leg pain, analyzing data from various credible sources.
- The findings included 8 randomized controlled trials and 8 observational studies, revealing fair evidence quality but noting a lack of high-quality studies, suggesting a moderate recommendation for these treatments.

Background: Percutaneous intradiscal hydrogel injection has been used to treat low-back pain (LBP) due to degenerative disc disease with or without mild radicular pain. Complications from these procedures are underreported. In this case lesson, the authors present a rare case of a patient with herniated intradiscal hydrogel following a minor trauma leading to neurological injury.

Minimally invasive intradiscal procedures such as allogeneic nucleus pulposus (NP) injection have the potential to fill the treatment gap between failed conservative care and spine surgery.
Objectives: Our study sought to evaluate the magnitude and durability of improvement in back function in patients with chronic lumbar discogenic pain followed for 6 months after a single intradiscal injection of minimally manipulated, off-the-shelf processed NP allograft (VIA Disc NP®, VIVEX Biologics, Inc.

Article Synopsis
- Discogenic chronic low back pain (cLBP) and radiculopathy are common and disabling, with traditional treatments often leading to further complications or degeneration of spinal discs.
- A new treatment strategy focuses on diagnosing and treating annulus fibrosus tears by using fibrin to seal these injuries and promote tissue growth, potentially offering a safer and more effective alternative.
- This method was tested in a retrospective cohort study involving patients who had not found relief from multiple prior treatments for cLBP lasting over six months, utilizing MRI for diagnosis.
