Radiopaque Gelified Ethanol Application in Lumbar Intervertebral Soft Disc Herniations: Croatian Multicentric Study.

Objective: Minimally invasive percutaneous spinal procedures are popular in trying to reduce spinal pain. The aim of this paper is to evaluate the safety of intervertebral disc chemonucleolysis and to report the effectiveness of a percutaneous, minimally invasive treatment for contained herniated intervertebral discs in the lumbar spine using the recently marketed radiopaque gelified ethanol. Methods: Pain relief before and after the procedure was self-evaluated by each patient using a verbal numeric scale (VNS) ranging from 0 to 10. Patients were also scored prior to procedure and after chemonucleolysis during several follow-up periods using the Roland-Morris low back pain and disability questionnaire (RMQ). Follow-up periods were defined as 0-6, 6-12, 12-18, 18-24, and 24-30 months. Clinically significant functional improvement (CSFI) was defined as a decrease of five or more points on the RMQ scale and a decrease of at least 50% of pain intensity using VNS. Results: Using the RMQ scale, CSFI was achieved in 20/29 patients in the first follow-up period, 20/27 patients in the second follow-up period, 9/12 patients in the third follow-up period, 8/9 patients in the fourth follow-up period, and 4/4 patients in the last follow-up period. Using the VNS rating, CSFI was accomplished in 19/29 patients in the first follow-up period, 19/27 patients in the second follow-up period, 9/12 patients in the third follow-up period, 8/9 patients in the fourth follow-up period, and 4/4 in the last follow-up period. Conclusions: Intradiscal application of gelified ethanol may be effective in pain reduction using the VNS and Roland-Morris low back pain and disability questionnaire. The treatment is safe and easy to handle.

Pain syndromes originating from cervical and thoracic spine remain to be a major public health problem. Medical expenses in general and surgical procedures associated with overall care for the neck and thoracic pain are high and growing. Furthermore, these two chronic pain conditions are also leading causes for missed workdays. Chronic pain syndromes originating from cervical spine are most commonly caused by degenerative changes of the facet joints. Cervi- cobrachial syndrome is most commonly caused by herniated discs. Diagnostic controlled blocks, performed in order to identify, the source of pain, often predetermine patient for further therapeutic minimally invasive interventions. If the chronic pain syndromes of the cervical and thoracic spine are caused by degenerative facet joints, patient can be offered neuroablative procedures using radiofrequency. In patients suffering from chronic cervical and thoracic pain caused by painful intervertebral disc minimally invasive intradiscal decompression procedures can be performed. In cases where the neck pain and radicular pain are caused by the central and foraminal spinal stenosis patients are advised epidural steroid injections. The purpose of above advised procedures, using steroids, local anesthetics and RF current, is to relieve patients' pain, allow optimal physical therapy, and improved functional capacity, consequently providing a better quality of life.

Back pain caused primarily by mechanical disorders is the most common type of back pain and it is usually found in young and middle-aged population, i.e. active population. This is why back pain is one of the most important public health problems. Treatment of pain syndrome affecting spine depends on a variety of factors and generally includes conservative and invasive methods. Relative indication for interventional and surgical procedures is long lasting back pain, the symptoms of which, predominantly pain, cause significant problems for the patient on performing everyday activities. Invasive/surgical treatment is applied after minimally 3 months of unsuccessful conservative treatment. Invasive and surgical procedures comprise a wide spectrum of interventions, from interventional and semi-interventional procedures, minimally invasive procedures to extensive, invasive operations that include instrumentation. The choice of intervention is based on clinical findings, duration and severity of pain and other symptoms, as well as on diagnostic reports. Despite recommendations based on the results of clinical studies, individual approach to each patient is the main principle of successful treatment.

Low back and radicular pain recently became a major public health problem. Medical expenses in general, and surgical procedures associated with overall care for the lower back pain are high and growing. Furthermore, these two chronic pain conditions are also leading causes for missed workdays. Degenerative changes of the intervertebral disc, facet joints, sacroiliac joint or disc herniation as described during imaging diagnostics may or may not be the cause of patients' lower back pain. Diagnostic blocks often precede further interventions in order to confirm or dispute a source of the lower back pain. Chronic lower back pain caused by painful intervertebral disc should be treated using biacuplasty. If the pain of the lumbar spine is caused by facet joints or sacroiliac joint, patient can be offered neuroablative procedures using radiofrequency. In cases where the low back and radicular pain are caused by the central and foraminal spinal stenosis patients are advised epidural steroid injections, unless claudications are present. Patients suffering from the chronic radicular pain may be treated with various nucleoplasty procedures or they may be offered percutaneous radiofrequent neuromodulation. The purpose of above advised procedures is to relieve patients' pain, allow optimal physical therapy, and improved functional capacity, consequently providing better quality of life.

[New techniques and prospects in invasive treatment in vertebrology]. / Novosti i perspektive u invazivnom lijecenju u vertebrologiji.

In this article authors outline new techniques and prospects in invasive treatment in vertebrology with emphasis on interventional and semi invasive procedures and minimally invasive surgery for lumbar disc herniation. They describe new approaches in neuroablative procedures for back pain treatment, in spinal fixation and in surgical treatment of scoliosis. Authors also report methods of great expectations which are not yet in use in our clinical practice but are promising like reconstruction of nucleus pulposus by autologous chondrocytes transplantation. New methods in cervical spine surgery are also discussed. The efficacy of each surgical method is pointed out. Apart from being informative, together with the corresponding article on patophysiology, magnetic resonance imaging and conservative treatment, these articles considering recent developments can be used as an aid in decision making when approaching these patients.
