Noninvasive electrical stimulation as an adjunct to fusion procedures: a systematic review and meta-analysis.

Objective: Noninvasive electrical stimulation represents a distinct group of devices used to augment fusion rates. However, data regarding outcomes of noninvasive electrical stimulation have come from a small number of studies. The goal of this systematic review and meta-analysis was to determine outcomes of noninvasive electrical stimulation used as an adjunct to fusion procedures to improve rates of successful fusion.

Super-Pedicle Osteotomy for Correction of Focal Thoracolumbar Kyphosis.

Background: Focal thoracolumbar kyphotic deformities require operative correction through osteotomies to restore normal spinal balance. Traditional osteotomies, such as the pedicle subtraction osteotomy, that are often used in the lumbar spine are less useful in the thoracolumbar region. The super-pedicle osteotomy is a pedicle-sparing wedge osteotomy that can be used for correction of kyphosis in patients with thoracolumbar deformities.

Early Postoperative Complications for Elderly Patients Undergoing Single-Level Decompression for Lumbar Disc Herniation, Ligamentous Hypertrophy, or Neuroforaminal Stenosis.

Background: Lumbar decompression for disc herniation is frequently performed on elderly patients, and this trend will continue as the population ages. Clinical reports on the complications of lumbar discectomy show good results and cost effectiveness in young or middle-aged patients.

Objective: To assess and compare the morbidity of single-level lumbar disc surgery for radicular pain in a cohort of patients greater than 80 yr of age to that of a middle-aged cohort.

Postoperative Complications for Elderly Patients After Single-Level Lumbar Fusions for Spondylolisthesis.

Objective: A large-scale study on postoperative complications of lumbar fusion surgery for spondylolisthesis comparing patients >80 years old with younger patients has not been performed. The purpose of this study is to assess the effects of extreme age (>80 years old) on early postoperative outcomes after single-level lumbar fusions for spondylolisthesis.

Methods: From a validated multicenter surgical database, 2475 patients who underwent a single-level lumbar fusion procedure for spondylolisthesis were selected retrospectively.

Preoperative Predictors of Spinal Infection within the National Surgical Quality Inpatient Database.

Background: Surgical-site infections (SSIs) are a major cause of morbidity and mortality, increasing the length and cost of hospitalization. In patients undergoing spine surgery, there are limited large-scale data on patient-specific risk factors for SSIs.

Methods: The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for all spinal operations between 2006 and 2012.

Placement of unilateral lag screw through the lateral mass of C-1: description of a novel technique.

Over the past several decades, many advancements and new techniques have emerged regarding the instrumentation and stabilization of the upper cervical spine. In this article, the authors describe a novel technique in which a unilateral lag screw was placed to reduce and stabilize a progressively widening fracture and nonunion of the right C-1 lateral mass approximately 8 weeks after the initial injury, which was sustained when a large tree branch fell onto the patient's posterior head and neck.

Minimally invasive anterior vertebroplasty for C-2 metastatic lesions.

The authors describe a technique for minimally invasive anterior vertebroplasty for treating metastatic disease of the C-2 vertebra and discuss its application in 2 cases. After a 2-cm lateral neck incision is made, blunt dissection is performed toward the anterior inferior endplate of the C-2 vertebra. An 11-gauge needle is introduced through a tubular sheath and tapped into the inferior endplate of C-2, with biplanar fluoroscopy being performed to confirm position.
