INTRODUCTION: Anterior cervical discectomy and fusion is commonly performed using an allograft or autograft implant and anterior screw-supported plate. There has been an increase in the use of standalone cage devices due to ease of use and studies suggesting a lower rate of acute post-operative dysphagia. We review our experience with standalone cage devices and identify risk factors, patterns of failure, and revision surgery approaches. MATERIALS AND METHODS: We performed a retrospective case-series of patients treated at a single tertiary care institution between March 2014 and March 2015...

Although degenerative spondylolisthesis (DS) and lumber disc herniation (LDH) are common causes of back pain, the associations between the lumbar facet joint angle orientation and tropism in these conditions are still contentious. The objective of the meta-analysis was to identify the role of facet joint orientation and tropism on the development of lumbar degenerative disease, including DS and LDH. Electronic searches of PubMed and Embase were conducted up to April 2017. P value<0.05 was regarded as significant...

The most common causes of low back pain in adolescents are spondylolysis and spondylolisthesis. Mechanical factors combined with rapid growth during adolescence place stress on the spine and can result in a stress fracture. Sports that require athletes to repeatedly place the spine in hyperextension may exacerbate both spondylolysis and spondylolisthesis. Many adolescent athletes with spondylolysis or low-grade spondylolisthesis have minimal symptoms and require no treatment or alteration in activity, including sports activity...

Low back pain is the most common complaint expressed by adult patients in the primary care setting, and the incidence of low back pain in adolescents is rising. Adolescents who are involved in athletics most commonly suffer from spondylolysis, spondylolisthesis, mechanical low back pain, and herniated disks, whereas adult athletes most commonly suffer from lumbosacral strain and herniated or degenerative disks. Initial nonsurgical management aims to reduce inflammation and noninvasively strengthen damaged tissues...

BACKGROUND CONTEXT: Patients with degenerative lumbar stenosis (DLS) adopt a forward flexed posture in an attempt to decompress neural elements. The relationship between sagittal alignment and severity of lumbar stenosis has not previously been studied. PURPOSE: We hypothesized that patients with increasing radiological severity of lumbar stenosis will exhibit worsening sagittal alignment. STUDY DESIGN: This is a cross-sectional study. PATIENT SAMPLE: Our sample consists of patients who have DLS...

STUDY DESIGN: A case-control study. OBJECTIVE: To determine whether parity and abdominal surgeries are associated with degenerative spondylolisthesis (DS). SUMMARY OF BACKGROUND DATA: DS is considered to be a major cause of low back pain (LBP) in the older population, with greater prevalence of DS among women. Because LBP and impaired abdominal muscle function are common during pregnancy and post-partum, parity-related abdominal muscle deficiency, resulting in poor spinal mechanics, could be a factor in the development of DS in women...

Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA) presents a management challenge. Degenerative lumbar spine conditions are known to decrease lumbar lordosis and limit lumbar flexion and extension, leading to altered pelvic mechanics and increased demand for hip motion. In this study, the effect of lumbar spine disease on complications after primary THA was assessed. The Medicare database was searched from 2005 to 2012 using International Classification of Diseases, Ninth Revision, procedure codes for primary THA and diagnosis codes for preoperative diagnoses of lumbosacral spondylosis, lumbar disk herniation, acquired spondylolisthesis, and degenerative disk disease...

OBJECTIVE Patient satisfaction is a commonly used metric in the current health care environment. While factors that affect patient satisfaction following spine surgery are complex, the authors of this study hypothesized that specific diagnostic groups of patients are more likely to be satisfied after spine surgery and that this is reflected in patient-reported outcome measures. The purpose of this study was to determine if the preoperative diagnosis-disc herniation, stenosis, spondylolisthesis, adjacent segment degeneration, or mechanical disc collapse-would impact patient satisfaction following surgery...

Traumatic high-grade spondylolisthesis in subaxial cervical spine is frequently associated with acute spinal cord injury and quadriparesis. There have been rare cases where such pathology demonstrates minimal to no neurological deficits. Assessment of the underlying biomechanics may provide insight into the mechanism of injury and associated neurological preservation. Patient 1 is a 63-year-old female presenting after a motor vehicle collision with significant right arm pain without neurological deficits. Imaging demonstrated C7/T1 spondyloptosis, associated with a locked facet on the left at C6/7 and a locked facet on the right at C7/T1, with a fracture of the left C7 pedicle and right C7 lamina...

BACKGROUND: Lumbar synovial cysts (LSCs) are an uncommon cause of radiculopathy and back pain. Open surgical treatment is associated with extensive bone resection and muscle trauma. The endoscopic tubular-assisted LSC resection has not been described in detail. Here the authors assessed the effectiveness of this technique for LSC resection. METHODS: Eleven patients (4 female and 7 male patients) were operated on via an ipsilateral approach for resection of LSC using an endoscopic tubular retractor system...

Lumbar lordosis (LL) is more prominent in women than in men, but the mechanisms responsible for this discrepancy are poorly defined. A recent study indicates that newborn girls have smaller vertebral cross-sectional area (CSA) when compared to boys-a difference that persists throughout life and is independent of body size. We determined the relations between vertebral cross-sectional area (CSA) and LL angle and whether sex differences in lumbar lordosis are related to sex differences in vertebral CSA. Using multi-planar magnetic resonance imaging (MRI), we measured vertebral cross-sectional area (CSA) and vertebral height of the spine of 40 healthy boys and 40 girls, ages 9-13 years...

OBJECTIVE: The objective of this review was to evaluate the efficacy of pulsed radiofrequency (PRF) treatment of pain associated with different spinal conditions. The mechanisms of action and biological effects are shortly discussed to provide the scientific basis for this radiofrequency modality. METHODS: We systematically searched for clinical studies on spinal clinical conditions using PRF. We searched the MEDLINE (PubMed) database. We classified the information in one table focusing on randomized controlled trials (RCTs) and other types of studies...

INTRODUCTION: Bone morphogenetic protein (BMP) is considered off-label when used to augment spinal arthrodesis in children and adolescents. There is a paucity of longer-term information on BMP use in this population. The purpose of this study was to determine the rate of BMP utilization in pediatric spinal arthrodesis, assess factors associated with BMP use in this population, and evaluate long-term outcome. METHODS: Spinal arthrodeses in patients 18 years and younger performed in New York State between 2004 and 2014 were identified through the Statewide Planning and Research Cooperative System database...

Osteoporosis is a bone disease that afflicts millions of people around the world, and a variety of spinal integrity issues, such as degenerative spinal stenosis and spondylolisthesis, are frequently concomitant with osteoporosis and are sometimes treated with spinal interbody fusion surgery. Previous studies have demonstrated the efficacy of strontium ranelate (SrR) treatment of osteoporosis in improving bone strength, promoting bone remodeling, and reducing the risk of fractures, but its effects on interbody fusion surgery have not been adequately investigated...
