Genicular nerve radiofrequency ablation (RFA) has recently gained popularity as an intervention for chronic knee pain in patients who have failed other conservative or surgical treatments. Long-term efficacy and adverse events are still largely unknown. Under fluoroscopic guidance, thermal RFA targets the lateral superior, medial superior, and medial inferior genicular nerves, which run in close proximity to the genicular arteries that play a crucial role in supplying the distal femur, knee joint, meniscus, and patella. ⋯ Although rare, these complications carry significant morbidities. Based on the detailed dissections and review of the literature, our investigation suggests that vascular injury is a possible risk of genicular RFA. Lastly, recommendations are offered to minimize potential iatrogenic complications.

The Potential Impact of Venobasillar System Morphology and Applied Technique on Epidural Cement Leakage with Percutaneous Vertebroplasty.
Bone cement leakage during vertebroplasty is a frequently reported complication with the potential for neural injury. ⋯ The type of venobasillar system should be taken into account when planning a vertebroplasty procedure as a magistral type of venobasillar system is associated with the increased rate of epidural cement leakage. It is important to try and achieve a large distance between the needle tip and the midline, especially when a magistral type of venobasillar system is present, to reduce the risk of epidural cement leakage.

Randomized Controlled Trial
Two-Year Outcome of Percutaneous Bipolar Radiofrequency Neurotomy of Sacral Nerves S2 and S3 in Spinal Cord Injured Patients with Neurogenic Detrusor Overactivity: A Randomized Controlled Feasibility Study.
Little research has been expended on the use of bipolar radiofrequency (RF) lesioning of sacral nerves in spinal cord injured (SCI) patients with neurogenic detrusor overactivity (NDO), and no study has been undertaken to demonstrate its long-term effect. ⋯ Percutaneous bipolar RF ablation of sacral nerves S2 and S3 effectively reduces urinary incontinence and improves quality of life (QoL) in SCI patients with NDO and the effects lasted over 2 years.

Multicenter Study
A Multicenter Clinical Study on Treating Post-Dural Puncture Headache with an Intravenous Injection of Aminophylline.
Post-dural puncture headache (PDPH) is the most common complication of lumbar puncture. Aminophylline has been reported to be effective in the prevention of PDPH in some clinical studies, but its efficacy for the treatment of PDPH has been unproven. ⋯ An IV injection of aminophylline may be an effective and safe early-stage treatment for PDPH.

Comparative Study
Percutaneous Vertebroplasty versus Conservative Treatment for One Level Thoracolumbar Osteoporotic Compression Fracture: Results of an Over 2-Year Follow-up.
We retrospectively compared the clinical and radiological results of percutaneous vertebroplasty with those of conservative treatment in the management of thoracolumbar osteoporotic compression fractures. Sixty-five patients who could be followed up for more than 2 years with thoracic and lumbar spine osteoporotic compression fractures, between January 2005 and October 2010, were reviewed. The patients were divided into 2 groups according to the type of management: group 1, non-operated group treated conservatively; group 2, operated group that underwent percutaneous vertebroplasty. ⋯ The overall VAS score and the VAS score until 6 months post-injury were statistically more improved in group 2 than in group 1 (P < 0.05 and P < 0.005, respectively). Overall, the compression ratio was statistically more improved in group 2 than in group 1 (P < 0.05). Early pain control and restoration of the compressed vertebral body are the beneficial and real effects of percutaneous vertebroplasty in patients with thoracolumbar osteoporotic compression fractures.
