The use of spinal cord stimulation (SCS) is well established in the treatment of neuropathic pain. This procedure has been approved in the United States for neuropathic pain of the trunk and limbs from various conditions. International use is variable based on governmental policy. Most studies showing efficacy have focused on pain primarily in the limbs for such conditions as complex regional pain syndrome (CRPS), sciatica, radiculitis, ischemic limb pain, and peripheral neuropathy. Data on success in neuropathic pain of the trunk and particularly of the axial back are limited. New understanding about the targets of neuromodulation and their treatment with novel neurostimulation approaches has led to a new dawn of enthusiasm for spinal cord stimulation for axial low back pain. ⋯ Improved technology and a better understanding of the goals of stimulation have led to a new ability to stimulate the axial low back and increase the effectiveness of these therapies to reduce pain. New paddle lead constructs, percutaneous paddle lead introduction, and other new technologies have led to an increased number of potential candidates for spinal cord stimulation. Optimizing the application of neurostimulation for chronic axial back pain will depend upon answering questions relating to patient selection, implantation technique, and stimulation parameters.

Percutaneous kyphoplasty is effective for pain reduction and vertebral height restoration in patients with osteoporotic vertebral fractures. However, in cases of severely collapsed fractures involving the loss of more than 70% of the vertebral height, kyphoplasty is technically difficult to perform and the outcomes remain unknown. ⋯ In patients with an anterior vertebral compression ratio more than 70% because of osteoporotic vertebral fracture, although the anterior height and kyphotic angle were significantly lower than those of patients with an anterior vertebral compression ratio of 30% to 50%, kyphoplasty significantly improved the degree of pain, restored the anterior vertebral height, and maintained the kyphotic angle. Therefore, kyphoplasty can be a useful approach in patients with an anterior vertebral compression ratio more than 70%.

The validity of using an electrocutaneous device for pain assessment in patients with cervical radiculopathy.
The purpose of this study was to evaluate the validity and preference for assessing pain magnitude with electrocutaneous testing (ECT) compared to the visual analogue scale (VAS) and Borg CR10 scale in men and women with cervical radiculopathy of varying sensory phenotypes. An additional purpose was to investigate ECT sensory and pain thresholds in men and women with cervical radiculopathy of varying sensory phenotypes. This is a cross-sectional study of 34 patients with cervical radiculopathy. ⋯ The use of the ECT pain magnitude matching paradigm for patients with cervical radiculopathy with normal sensory phenotype shows good linear association with arm pain VAS (R(2) = 0.39), neck pain VAS (R(2) = 0.38), arm pain Borg CR10 scale (R(2) = 0.50) and neck pain Borg CR10 scale (R(2) = 0.49) suggesting acceptable validity of the procedure. For patients with hypoesthesia and hyperesthesia sensory phenotypes, the ECT pain magnitude matching paradigm does not show adequate linear association with rating scale methods rendering the validity of the procedure as doubtful. ECT for sensory and pain threshold investigation, however, provides a method to objectively assess global sensory function in conjunction with sensory receptor specific bedside examination measures.

The aim of our study is to assess the diagnostic value of Technituim-(99m)-Methyle diphosphonate ((99m)Tc-MDP) Bone scintigraphy in the assessment of children with back pain. ⋯ Bone isotope scan is a sensitive imaging modality in the assessment of pediatric patients with back pain. It is a reliable modality to detect and role out most benign and aggressive serious etiologies.
