BACKGROUND: Intradiscal cement leakage (ICL) is a common complication following percutaneous vertebroplasty (PVP). However, the risk factors for such a complication are under debate and there is no accurate predictive nomogram to predict ICL. OBJECTIVES: To establish an effective and novel nomogram for ICL following PVP in patients with osteoporotic-related vertebral compression fractures (OVCFs). STUDY DESIGN: This was a retrospective study approved by the Institutional Review Board of our institution...

A number of geometrically-detailed passive finite element (FE) models of the lumbar spine have been developed and validated under in vitro loading conditions. These models are devoid of muscles and thus cannot be directly used to simulate in vivo loading conditions acting on the lumbar joint structures or spinal implants. Gravity loads and muscle forces estimated by a trunk musculoskeletal (MS) model under twelve static activities were applied to a passive FE model of the L4-L5 segment to estimate load sharing among the joint structures (disc, ligaments, and facets) under simulated in vivo loading conditions...

In the panorama of available musculoskeletal modeling software, AnyBody software is a commercial tool that provides a full body musculoskeletal model which is increasingly exploited by numerous researchers worldwide. In this regard, model validation becomes essential to guarantee the suitability of the model in representing the simulated system. When focusing on lumbar spine, the previous works aimed at validating the AnyBody model in computing the intervertebral loads held several limitations, and a comprehensive validation is to be considered as lacking...

BACKGROUND: The causes of ASD are still relatively unknown. Correlation between clinical status of patients and radiological MRI findings is of primary importance. The radiological classifications proposed by Pfirmann and Oner are most commonly used to assess intradiscal degenerative changes. The aim of the study was to assess the influence of the extension of spine fixation on the risk of developing ASD in a short time after surgery. METHODS: A total of 332 patients with spinal tumors were treated in our hospital between 2010 and 2013...

Intradiscal O2-O3 injections are conventionally used as a minimally invasive treatment for lumbar disc herniation in patients not responding to conservative treatments. The aim of the present study is to report data of long-term imaging follow-up (3 years) of patients treated with intradiscal O2-O3 lumbar chemiodiscolysis. We evaluated the changes of disc volume and the modifications in disc appearance (in terms of disc degeneration) and endplate changes (according to Modic), comparing the results with a control group of patients...

The intradiscal application of mesenchymal stem cells (MSC) is considered a promising strategy for intervertebral disc (IVD) regeneration. Although many studies have been published, the feasibility and regenerative effects of intradiscal MSC application has not been evaluated in an animal model suffering from naturally occurring degenerative disc disease. Six German Shepherd Dogs suffering from naturally occurring degenerative IVD disease were included. Autologous MSC were isolated from bone marrow (iliac crest) and cultured for 3 weeks...

The management of low back pain should always start with a conservative approach; however, when it fails, intervention is required and at that moment the most appropriate choice remains unclear. Before invasive surgery, minimally invasive techniques can be adopted. In European trials and in a trans-Canadian clinical trial 03 ozone has been used successfully. In total over 50,000 patients have been treated safely. Ozone is a gas normally present in the atmosphere with potent oxidizing power; it has been used for percutaneous intradiscal injection combined with oxygen (O2O3) at very low concentrations for 15 years in Europe...

Intervertebral disc degeneration (IDD) is considered to be the main cause of many spinal disorders; however, its underlying pathophysiology is not clearly understood. Recent studies indicate that excessive mechanical loading may serve a major role in the initiation of IDD. The aim of the present study was to explore the effect of noninvasive cumulative axial loading on the intervertebral discs of the lumbar spine using a novel rabbit model. Rabbits in the experimental group were placed into individual tubes specifically designed to force maintenance of an upright posture and were loaded with a heavy collar to increase the intradiscal pressure of their lumbar spine...

Tobias A Mattei
BACKGROUND: Previous studies have demonstrated lower rates of cement extravasation when comparing balloon kyphoplasty with vertebroplasty, an effect attributed to the low-pressure injection. However, in patients with isolated endplate fractures, balloon kyphoplasty may lead to further endplate damage and increased risks of intradiscal extravasation. METHODS: The author provides a stepwise description of a new technique called cavitational kyphoplasty that allows targeted low-pressure cement injection without the necessity of balloon inflation...

Background. : A substantial part of low back pain (LBP) originates from degeneration of the intervertebral disc. To confirm the diagnosis of discogenic pain, provocation discography seems the best available tool. However, provocation discography is also considered to be a controversial and subjective test because the patient's personal pain response is the most crucial for the result of the test. Recently, an in vivo porcine study and a study in nine human subjects showed passing of pressure to the adjacent discs during discography...

Setting.:  Epidural hematoma rarely complicates interventional spine procedures. While anticoagulant and antiplatelet drugs increase bleeding risk, cessation may precipitate serious thromboembolic events. The Spine Intervention Society (SIS) and American Society of Regional Anesthesia and Pain Medicine (ASRA) put forth guidelines that dissent with regard to management of hemostatically active agents during commonly performed spinal injections. Objective.:  To validate an antiplatelet/anticoagulant management table based on modifications of the SIS 2013 and ASRA 2015 guidelines...

Background: Active discopathy is associated with a specific phenotype of chronic low back pain (LBP). Local inflammation has a role in active discopathy-associated symptoms.

GOAL: The main purpose of the present study was to propose a recognizing method to analyze characteristics of symmetric lifting of skilled logistic experts by center of pressure (CoP) trajectories. Although it has been known that good posture helps reduce the intradiscal loads on lumbar discs, the most significant problem was that most of logistic workers did not know whether the current posture was proper or not. METHODS: The experiment of lifting was performed three times under 18 kg loads with closed eyes...

We report a patient with a wooden foreign body granuloma in the intervertebral disc space being symptomatic 17 years after a paraspinal penetrant trauma. According to the our result of the search for wooden foreign body granulomas, this is the first case suffered from a wooden foreign body granuloma in the intervertebral disc space that reported in the literature. In this report, we emphasized the importance of rigorous examination and follow up in paraspinal wooden penetrant traumas.

OBJECTIVE: This study aims to investigate the curative effects and mechanism of radiofrequency ablation nucleoplasty in the treatment of cervical vertigo. METHODS: A total of 27 patients diagnosed with cervical vertigo from January 2012 to October 2014 received treatment of radiofrequency ablation nucleoplasty. The narrow-side vertebral artery diameters were examined by using Philips 1.5-T body dual-gradient MRI system. The haemodynamic parameters were detected by using transcranial Doppler sonography...

OBJECTIVE: The objective of this review was to evaluate the efficacy of pulsed radiofrequency (PRF) treatment of pain associated with different spinal conditions. The mechanisms of action and biological effects are shortly discussed to provide the scientific basis for this radiofrequency modality. METHODS: We systematically searched for clinical studies on spinal clinical conditions using PRF. We searched the MEDLINE (PubMed) database. We classified the information in one table focusing on randomized controlled trials (RCTs) and other types of studies...
