Purpose: Aim of this study is to assess the effectiveness of O2-O3 percutaneous chemiodiscolysis by evaluating volumetric changes in lumbar disc herniation on magnetic resonance imaging, in order to identify possible pre-treatment factors affecting such changes Methods: Between January 2014 and December 2017, a total of 87 patients with low back pain and 103 lumbar disc herniations with MRI confirmation were considered for O2-O3 chemiodiscolysis. The volume of each herniated disc was determined before and after the treatment.
Results: Multiple linear regression analysis showed a strong correlation between post-treatment LDH volume percent change and both pre-treatment LDH volume and pre-treatment EQ-VAS (p<0.05), while age showed only a weak positive correlation with post-treatment LDH volume percent change (p<0.1). No association was found for other factors, such as sex and herniation disc level.
Conclusions: In conclusion, age, baseline LDH volume and self-assessed disease severity score could represent three easy accessible outcome predictive parameters to consider when intradiscal O2-O3 chemiodiscolysis is envisaged. Better results after intradiscal O2-O3 chemiodiscolysis were obtained in older patients with higher pre-treatment LDH volume and low-moderate pre-treatment EQ-VAS.

Background Context: Lumbar interbody fusion (LIF) is a common surgical intervention for treating lumbar degenerative disorders. Increasing demand has contributed to ever-increasing healthcare expenditure and economic burden. To address this, cost-utility analyses (CUAs) compare value in the context of patient outcomes.

With a prevalence of over 90% in people over 50, intervertebral disc degeneration (IVDD) is a major health concern. This weakening of the intervertebral discs can lead to herniation, where the nucleus pulpus (NP) leaks through the surrounding Annulus Fibrosus (AF). Considering the limited self-healing capacity of AF tissue, an implant is needed to restore its architecture and function.

Background: Aneurysmal bone cysts (ABCs) are slow-growing, expansile bone tumors most often observed in the long bones and lumbar and thoracic spine. Anterior column ABCs of the spine are rare, and few cases have described their surgical management, particularly for lesions with extension into the odontoid process and the bilateral C2 pedicles. In the present case, the authors describe a two-stage strategy for resection of a symptomatic 2.

Background: Intervertebral disc (IVD) degeneration is the main cause of neck pain. Although conventional magnetic resonance imaging can detect morphological changes in intervertebral disc degeneration, it cannot provide accurate and objective evaluations. Magnetic resonance diffusion tensor imaging (DTI) reflects the microstructural changes in tissues by describing the diffusion of water molecules.

Objectives: To compare the effectiveness of preganglionic transforaminal epidural steroid injection (TFESI) with preganglionic plus postganglionic TFESI.
Methods: Patients with unilateral radicular pain and disc pathology were randomly assigned to either the preganglionic group or the preganglionic plus postganglionic group. All patients were evaluated using a numeric rating scale (NRS) and a patient satisfaction scale (PSS) at the third week and the third month after treatment.
