This study will provide information on the effectiveness of cryoneurolysis for patients with facet joint pain syndrome, and help to establish whether cryoneurolysis should be implemented in clinical practice for this patient population.
The investigators will select two study groups from a population of patients with severe chronic low back pain (CLBP) of facet joint (FJ) origin already treated with conventional radiofrequency ablation (CRFA) of the medial branch of the dorsal ramus (MBDR) and that failed to obtain a 50% pain reduction measured through the numerical rate scale (NRS) for at least 3 months. Severe CLBP is considered a value of at least 7 by NRS pain assessment. The first group will be characterized by a nociceptive/mechanic type of back pain. The second group of study will be characterized by a neuropathic type of back pain. This difference will be established by a DN4 score of at least 4 points (Doleur Neurophatique 4). The patients in the group with nociceptive/mechanic back pain will be randomly assigned to conventional radiofrequency ablation or to water cooled radiofrequency (WCRF) of the MBDR. The patients in the group with neuropathic back pain will be randomly assigned CRFA of MBDR or to pulsed radiofrequency (PRF) of the dorsal root ganglia (DRG). The study will be carried on for an estimated time of 3 years. Primary outcomes will be: - at least 50% back pain reduction for at least 3 months evaluated through NRS, with a subcategorization of results that will consider a mean difference in effect (respect to the initial evaluation, with an initial NRS score of at least 7) of 1 point on NRS pain scale as small/modest, 2 points as moderate, more than 2 as large/substantial between the case/control study groups. - improvement of low back pain disability: 10 points increase on the Oswestry Low Back Pain Disability Questionnaire (ODI) have been proposed as minimal clinically important differences, between 10 and 20 as moderate, more than 20 as large/substantial clinical improvement at month 3 and 6. Secondary outcome will be evaluated by the 12-item short form survey SF12, accordingly with the clinical pre-interventional findings, analgesic intake at month 1-3-6 (if increased, unchanged, decreased, in dosages or number of pain killers' assumption). Groups sizes: will be calculated based on the disease's incidence and the outcome targets.
Chronic neck pain is a common disorder for spine specialists. Radiofrequency ablation of medial branches has been proven effective in selected patients for relieving pain. A newer radiofrequency ablation cannula has been developed (multi-tined), allowing perpendicular access. It is proposed as an alternative to the more technically challenging traditional approach. This study aims to compared the technical and clinical aspects of both techniques.
In suspected facet joints pain, it is recommended to perform nerve blocks to establish the diagnosis with positive results being and indicator of successful of most permanent treatment of facet pain by rhizolysis. Nevertheless, the usefulness of intraarticular joint injection for diagnosis and prediction of successful neurolysis have been scarcely studied. The main purpose of this trial is to compare both methods, nerve block and intra articular injection, in diagnosis and treatment of facet joints pain.
The purpose of this study is to test the efficacy of radiofrequency ablation of the medial branch nerves (RFA-MBN) in relieving pain and improving physical function in patients with subacute and chronic vertebral compression fractures (VCF).
We propose here to evaluate the precision of lumbar thermocoagulation performed under a transverse ultrasound approach by performing a fluoroscopic control once the needle in the desired position. The effectiveness of the technique will be assessed by measuring different pain and disability scores at six weeks post-thermocoagulation: the Visual analogue pain Scale score (VAS) and the Oswestry disability score (ODI) will be collected, compared to that of the conventional fluoroscopic technique.
The purpose of this study is to determine if cortisone shots in the neck are helpful in patients with certain MRI findings. Additionally, the investigators hope to learn if cervical facet joint steroid injections are beneficial in the subset of patients with MRI findings consistent with facet joint synovitis.
A gap of knowledge exists on the understanding of the acute effects of stabilization exercises on pain, disability and physical performance when applied after radiofrequency denervation. Therefore, the main objective of this study is to show the effects of stabilization exercises when started in acute period and also reduce the frequency of recurrence low back pain of patients with FJS after radiofrequency denervation.
Low back pain is a major contributor to the chronic pain burden in the community. Although there are numerous pain generators in the spine, lumbar facet joints are one of the most common sources of pain. A variety of measures such as physiotherapy, oral analgesics and minimally invasive injections are used to treat lumbar facet joint pain. Facet joint steroid injections and radiofrequency denervations of the facet joint are the most commonly performed minimally invasive pain procedures for lumbar facet joint pain. Radiofrequency denervation is carried out by thermal lesioning of the medial branches that supply the facet joints. Conventionally two medial branches have been shown to innervate one facet joint and based on this, the norm is to lesion two nerves to denervate one facet joint. However, there is some variation in the nerve supply which may account for failure or false negative results of the diagnostic blocks. The aim of the present study is to explore the feasibility of sensory mapping, thereby referral pattern of the lumbar medial branches using suprathreshold stimulation and to correlate the referral patterns with painful areas in the back and leg. It will also test if the present method of lesioning two nerves to denervate one facet joint is appropriate.
