RESUMO
Radicular lumbar back pain is an important public health problem not yet benefiting from a unequivocal treatment approach. Medical and physical therapies represent the first solution; however, when these fail, the second therapeutic step is still controversial and mini-invasive treatments may play an important role. In these cases oxygen-ozone therapy has been proved to be a very safe and effective option that is widely used with different modalities. This paper, by reviewing oxygen-ozone therapy literature data, aims to describe the rationale of oxygen-ozone therapy for the treatment of lumbar disk herniations, propose an effective procedural technique and clarify patient selection criteria; furthermore, complications and follow-up management are also considered.

This study assessed the one-year clinical and radiographic outcomes, in terms of pain-relief, vertebral re-fracture and complications, after vertebroplasty (VP) using a new osteoconductive cement (calcium triglyceride bone cement - Kryptonite™ bone cement, Doctors Research Group Inc., Southbury, CT, USA) to treat osteoporotic vertebral compression fractures. Sixteen consecutive osteoporotic patients (12 women and four men, mean age 68+/-10.5) were treated with VP using Kryptonite™ bone cement for a total of 20 vertebral fractures. All the patients complained of a pain syndrome resistant to medical therapy and all procedures were performed under fluoroscopy control with neuroleptoanalgesia using a monopedicular approach in 12 patients and bipedicular approach in four patients. All patients were studied by MR and MDCT and were evaluated with the visual analogue scale (VAS) and the Oswestry disability index (ODI) before treatment and at one and 12 months after the procedure. A successful outcome was observed in 80% of patients, with a complete resolution of pain. Differences in pre and post treatment VAS and ODI at one-year follow-up were significant (P<0.0001). We observed a disk and venous leakage in 66% of patients but only in one case did an asymptomatic pulmonary embolism occur during cement injection. Two cases of vertebral re-fractures at distant metamers were observed during follow-up. VP using Kryptonite bone cement is a helpful procedure that allows complete and long-lasting resolution of painful vertebral symptoms. The cost of the material is very high and the rate of disk and venous leakage is too high compared to standard cement.

We present a case report of a 33-year-old woman with back pain for several months which was resistant to medical treatment. Thoracolumbar MRI and multidetector CT showed an aneurysmal bone cyst intersecting the body and pedicles of L5. Minimally invasive treatment was performed with percutaneous injection of osteoconductive cement (Cerament) to induce sclerosis and bone remodeling of the bone cyst lesion with an analgesic effect. Before treatment, spinal angiography was performed to exclude arterial afferents. No bone biopsy was done. Under general anesthesia and fluoroscopic guidance, a first vertebroplasty was performed by a bilateral transpedicular approach using the osteoconductive cement followed 2 months later by a second treatment with CT-fluoro-guided direct injection of Cerament. No complications occurred during the procedure. At 4 and 6 months follow-up the MRI/CT showed sclerotic bone remodeling of the walls of the aneurysmal cyst with clinical improvement.
