Case report. ⋯ This minimal access procedure was effective in completely relieving pain from a metastatic deposit at C2, while adequately stabilizing the vulnerable segment by the injection of polymethyl methacrylate. The transoral route requires meticulous fluoroscopic control to prevent the leakage of polymethyl methacrylate but provides the most direct access to the C2 body.

Comparative StudyThe effects of cement volume on clinical outcomes of percutaneous vertebroplasty.
There exists significant variability in the volume of polymethylmethacrylate cement injected during percutaneous vertebroplasty. Larger cement volumes injected may be associated with better clinical outcomes, but larger volumes may also be associated with greater risk of complications related to cement leakage. We describe an analysis of the association between clinical and procedural variables, including cement volume injected, and the clinical outcomes of patients treated with single-level vertebroplasty. ⋯ Vertebroplasty operators need not feel compelled to achieve particular cement volumes injected in the pursuit of better clinical outcomes but should strive to achieve the maximal safe filling of individual vertebral bodies.

Percutaneous vertebroplasty in patients with intractable pain from osteoporotic or metastatic fractures: A prospective study using quality-of-life assessment.
Percutaneous vertebroplasty (PVP) is a minimally invasive outpatient procedure whereby vertebral compression fractures are stabilized by the injection of bone cement, or polymethyl methacrylate (PMMA). Rapid partial or complete pain relief can usually be achieved through this procedure. We prospectively evaluate the efficacy of PVP in the relief of pain and improvement in quality of life of patients with intractable pain from osteoporotic and metastatic fractures. ⋯ PVP in osteoporotic and metastatic fractures significantly improved many patients' global quality-of-life scores and function by markedly decreasing their back pain and reducing their intake of pain medications. The procedure is safe, with no serious complications noted in our study.

Comparative StudyTreatment of painful compression vertebral fractures with vertebroplasty: results and complications.
The aim of this paper is to assess the effectiveness and safety of percutaneous vertebroplasty in patients with focal pain caused by compression vertebral body fractures. ⋯ Our experience confirms the effectiveness of vertebroplasty in the treatment of pain caused by vertebral fractures. If the indications are respected the improvement of symptoms is often immediate, such as the return of mobility, and patient satisfaction with surgery is higher. The use of appropriate guiding systems limits the number of complications.
