ABSTRACT Pulsed radiofrequency (PRF), a technology related to continuous radiofrequency, is unique in that it provides pain relief without causing significant damage to nervous tissue. The mechanism by which PRF controls pain is unclear, but it may involve a temperature-independent pathway mediated by a rapidly changing electrical field. Although much anecdotal evidence exists in favor of PRF, there are few quality studies substantiating its utility.

    ABSTRACT: This paper presents a bipolar porous probe for implantable nerve stimulation treatment utilizing minimally invasive surgery. The probe's design features micro-wings and pores for cell growth that promote long term fixation in the body. Two recording pairs detect whether cells grow into the pores, and one pair of stimulating pads stimulates the target nerve. The probe is composed of three layers: two SU-8 layers and one flexible printed circuit (FPC) layer. Results show that SU-8 films can increase the product of the area moment of inertia and Young's Modulus by 9.04% from 5.86×10-6 N·m2 to 6.93×10-6 N·m2 and that micro-wings can increase the force of fixation by 38.58% from 0.114 N to 0.158 N. From the impedance test, the impedance of the pores in gelatin is shown to be lower than the ones in air, demonstrating that the two recording pairs are promising for detecting cells growth.

    ABSTRACT: Sacroiliac joint pain is a common cause of low back pain and can be a diagnostic challenge. Interventional treatment may be considered after patients fail conservative/noninterventional treatments. This article provides a review of current interventional procedures for the treatment of sacroiliac joint pain including sacroiliac joint injection, noncorticosteroid injection and radiofrequency ablation.

    ABSTRACT: Trigeminal neuralgia (TN) is neuropathic pain which can involve any part or side of the face. The objectives of this study were to find the most common branch of trigeminal nerve affected and the most common side involved. This Cross sectional study was carried out on 100 patients of trigeminal neuralgia in one year time. The diagnosis was based on a detailed history, clinical examination and control of pain by carbamazepine being taken supplemented by radiographic investigations. The collected data was analysed by SPSS 16. The age of the patients varied from 40 to 80 years with a mean age 54 years at the time of presentation. The males to females ratio was 1:2. The right side of the face was found to be involved in seventy patients (64 %) and left side in (36 %). No case presented with bilateral involvement. The Mandibular division was most commonly involved in this study (n = 55; 55%) and least was ophthalmic divisions (n = 6; 6%). This study demonstrated numerous clinical similarities of trigeminal neuralgia afflicting different populations. Right side was more involved along with mandibular division the most commonly affected. However studies needs to be done to know the exact reasons of involvement of the affected side and branches.
