BACKGROUND: Pedicle screw instrumentation for treating spinal disorder is becoming increasingly widespread. Many studies have advocated its use to facilitate rigid fixation for spine; however, adjacent segmental disease is a known complication. Instrumented fusion for osteoporotic spines remains a significant challenge for spine surgeons. Prophylactic vertebroplasty for adjacent vertebra has been reported to reduce the complications of junctional compression fractures but has raised a new problem of vertebral subluxation...

BACKGROUND: Penetrating neck injury is an important trauma subset but is relatively rare, especially when involving the posterior cervical column. Rupture of the neck restraints, including the interspinous and flavum ligaments, can create serious cervical instability that requires special consideration when managing the airway. However, no detailed information regarding airway management in patients with profound posterior neck muscle laceration and direct cervical ligament disruption by an edged weapon is yet available in the literature...

AIM OF THE STUDY: to gather clinical and laboratory data on rheumatoid arthritis patients with cervical spine damage (incidence and prevalence, correlation between duration of disease and the time of lesion onset, to assess signs and symptoms and the role of laboratory investigations). The spine is an axial organ with an important role in support and resistance. It is a pillar with a very complex morphological and functional structure. The vertebral column is crossed by many kinematic chains...

BACKGROUND CONTEXT: In multiple myeloma, patients may develop rapidly progressive, lytic, spinal lesions. These may result in spinal instability, but instrumented stabilization may fail because of poor bone quality. In addition, patients are immunocompromised and are therefore at increased risk of deep infection. PURPOSE: The aim was to describe a patient presenting with an unstable fracture subluxation of the thoracic spine secondary to myeloma, successfully treated with non-surgical management...

Kyphoplasty and vertebroplasty are established treatment methods to reinforce fractured vertebral bodies. In cases of previous pedicle screw instrumentation, vertebral body cannulation may be challenging. The authors describe, for the first time, an approach through the adjacent inferior vertebra and disc space in the thoracic spine for cement augmentation. A 78-year-old woman underwent posterior fusion with pedicle screws after vertebrectomy and reconstruction with cement and Steinmann pins for a pathological T-7 fracture...

BACKGROUND: This paper intends to clarify clinical and anatomical features as well as pathological conditions of surgically treated adult patients with occipitalization of the atlas. METHODS: The authors reviewed 12 consecutive adult patients with occipitalization of the atlas who underwent surgery for myleopathy in our hospital. Mainly using preoperative computed tomography and three-dimensional computed tomography angiography, we investigated their anomalies of the osseous structures and vertebral artery at the cervical spine including the craniovertebral junction (CVJ)...

Chiropractors commonly treat children for a variety of ailments by manipulating the spine to correct a 'vertebral subluxation' or a 'vertebral subluxation complex' alleged to be a cause of disease. Such treatment might begin soon after a child is born. Both major American chiropractic associations - the International Chiropractic Association and the American Chiropractic Association - support chiropractic care for children, which includes subluxation correction as a treatment or preventive measure. I do not know of any credible evidence to support chiropractic subluxation theory...

STUDY DESIGN: A retrospective study. OBJECTIVE: Aim of the study was to investigate morphological differences in the vertebrae of scoliosis secondary to neurofibromatosis type 1 (NF1-S) with and without paraspinal neurofibromas and to identify the relationship between paraspinal neurofibromas and vertebral deformity. SUMMARY OF BACKGROUND DATA: Scoliosis is the most common orthopedic manifestation of NF1. Erosion or infiltration of the bone by localized neurofibromas was suggested as one of the primary etiology for the vertebral deformity...

OBJECT: Screening for vertebral artery injury (VAI) following cervical spine fractures is routinely performed across trauma centers in North America. From 2002 to 2007, the total number of neck CT angiography (CTA) studies performed in the Medicare population after trauma increased from 9796 to 115,021. In the era of cost-effective medical care, the authors aimed to evaluate the utility of CTA screening in detecting VAI and reduce chances of posterior circulation strokes after traumatic cervical spine fractures...

INTRODUCTION: Early treatment of initial anterior glenohumeral dislocation in young patients is controversial and the interest of surgery, and notably arthroscopic stabilization, has not been demonstrated. A prospective study was therefore performed to assess (1) short-to-medium-term recurrence rate, (2) functional outcome, and (3) and medium-term osteoarthritis rate. HYPOTHESIS: Early arthroscopic stabilization by anterior capsule-labrum reinsertion after initial anterior shoulder dislocation is associated with low recurrence rate...

INTRODUCTION: Crystal-induced arthritis of the lateral atlantoaxial joint may be intimately involved in acute neck pain in the elderly. Patients typically have a good prognosis, and symptoms usually subside within a few weeks. On the other hand, septic arthritis of the lateral atlantoaxial joint requires early diagnosis and antibiotic treatment. Diagnostic delay is a risk factor for an unfavorable outcome of vertebral osteomyelitis. Even though septic arthritis of the lateral atlantoaxial joint is a very rare clinical entity, it is important to differentiate septic arthritis from crystal-induced arthritis...

PURPOSE: Hemivertebrae, associated with a failure in the formation and fusion of vertebral body ossification nuclei, are a common cause of thoracic or lumbar scoliosis. A cervical location is rare and even rarer as a cause of cervical subluxation in flexion and extension (for which only one previous case has been found). CASE REPORT: We report on the case of a 7-year-old female patient, who was examined for a cervical fusion defect, consisting of a posterior C4 hemivertebra and a left hemiblock from C5 to C7...

INTRODUCTION: In degenerative adult spinal deformity (ASD), sagittal malalignment and rotatory subluxation (RS) correlate with clinical symptomatology. RS is defined as axial rotation with lateral listhesis. Stereoradiography, recently developed for medical applications, provides full-body standing radiographs and 3D reconstruction of the spine, with low radiation dose. HYPOTHESIS: 3D stereoradiography improves analysis of RS and of its relations with transverse plane and spinopelvic parameters and clinical impact...

Acute angulation at the thoracolumbar junction with segmental subluxation of the spine occurring at the level above an anteriorly hypoplastic vertebra in otherwise normal children is a rare condition described as infantile developmental thoracolumbar kyphosis. Three patient series with total of 18 children have been reported in the literature. We report five children who presented with thoracolumbar kyphosis and discuss the treatment algorithm. We reviewed the medical records and spinal imaging at initial clinical presentation and at minimum two-year follow-up...

BACKGROUND: The literature pertaining to chiropractic students' opinions with respect to the desired future status of the chiropractic physician is limited and is an appropriate topic worthy of study. A previous pilot study was performed at a single chiropractic college. This current study is an expansion of this pilot project to collect data from chiropractic students enrolled in colleges throughout North America. OBJECTIVE: The purpose of this study is to investigate North American chiropractic students' opinions concerning professional identity, role and future...
