Randomized Controlled Trial
1-Year Results of a Randomized Controlled Trial of Conservative Management vs. Minimally Invasive Surgical Treatment for Sacroiliac Joint Pain.
Low back pain (LBP) emanating from the sacroiliac joint (SIJ) is a common finding. Devices to fuse the SIJ are now commercially available, but high-quality evidence supporting their effectiveness is limited. ⋯ For patients with chronic LBP originating from the SIJ, minimally invasive SIJF with triangular titanium implants was safe and more effective than CM in relieving pain, reducing disability, and improving patient function and quality of life. Our findings will help to inform decisions regarding its use as a treatment option in this patient population.Key words: Sacroiliac joint dysfunction, pelvic girdle pain, randomized controlled trial, quality of life, spine implants.

Serious Adverse Events Associated with Readmission Through One Year After Vertebral Augmentation with Either a Polyetheretherketone Implant or Balloon Kyphoplasty.
The KAST (Kiva Safety and Efficacy) investigation device exempt (IDE) study indicated that the majority of patients responded equally well to vertebral augmentation using either an implant-based approach or balloon kyphoplasty (BK). Additional investigation has suggested that a subset of patients may benefit further by avoiding repeated readmissions due to serious adverse events (SAEs) if they receive one vertebral augmentation approach over another. ⋯ The augmentation approaches compared here have similar pain relief and quality of life effects; the implant showed a lower risk of readmissions.

Effects of Pulsed Versus Conventional Versus Combined Radiofrequency for the Treatment of Trigeminal Neuralgia: A Prospective Study.
During radiofrequency bursts of energy are applied to nervous tissue. The clinical advantages of this treatment remain unclear. ⋯ The best results were observed in the CCPRF group, followed by the CRF group, and then the PRF group.Key words: Pulsed, continuous, radiofrequency, trigeminal neuralgia, Gasserian ganglion.

Sonographic Guidance for Supraclavicular Brachial Plexus Blocks: Single vs. Double Injection Cluster Approach.
The cluster approach for supraclavicular brachial plexus block (SC-BPB) can be easily performed but may result in asymmetric local anesthetic (LA) spread. The authors hypothesized that the use of a cluster approach in each of the 2 planes would achieve better 3-dimensional LA distribution than the traditional single cluster approach. ⋯ The DI approach can be performed easily as single cluster approach and increases the consistency of ultrasound-guided SC-BPB over the SI approach in terms of the rate of blocking of all 4 nerves. Key words: Brachial plexus block, corner pocket approach, cluster approach, multiple injection, supraclavicular block, ultrasound.

Posture Influences the Extent of Spread of Contrast Medium During Thoracic Epidurography: A Prospective Randomized Trial.
Various factors influencing the distribution of sensory blockade in epidural anesthesia have been identified; however, reports on the effects of gravity and different postures in thoracic epidural anesthesia have been rare. Medications may be injected with the lateral decubitus or the neutral position; however, it is unclear whether the distribution range of medication is similar or significantly different between these 2 postures. ⋯ Group L demonstrated a more extensive distribution of contrast medium for both the cranial and caudad directions compared to group P.Key words: Epidural, thoracic, contrast medium, injections.
