Cost-utility of revisions for cervical deformity correction warrants minimization of reoperations.

J Spine Surg 2018 Dec;4(4):702-711

Department of Neurological Surgery, University of California, San Francisco, San Francisco, CA, USA.

Background: Cervical deformity (CD) surgery has become increasingly more common and complex, which has also led to reoperations for complications such as distal junctional kyphosis (DJK). Cost-utility analysis has yet to be used to analyze CD revision surgery in relation to the cost-utility of primary CD surgeries. The aim of this study was to determine the cost-utility of revision surgery for CD correction. Read More

Department of Orthopedics, The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, Wenzhou, China.

Introduction: The optimal treatment for burst fractures of the thoracolumbar spine is controversial. The addition of screws in the fractured segment has been shown to improve construct stiffness, but can aggravate the trauma to the fractured vertebra. Therefore, optimised placement of two pedicle screws at the fracture level is required for the treatment of thoracolumbar burst fractures. Read More

Medium-term clinical outcomes of laminoplasty with adjunct short anterior fusion in multilevel cervical myelopathy.

Ci Ji Yi Xue Za Zhi 2019 Jan-Mar;31(1):47-51

Department of Orthopedics, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan.

Objectives: Expansive open-door laminoplasty (EOLP) is effective for multilevel cervical spondylotic myelopathy (MCSM). When MCSM is combined with one- or two-level segmental kyphosis, instability, or major anterior foci, EOLP with short-segment anterior cervical fusion (ACF) results in good short-term neurological recovery and can preserve postoperative range of motion (ROM). The objective of this study was to evaluate the medium-term clinical outcomes of this procedure and to analyze the risk factors affecting the neurological function at the last follow-up. Read More

NUTRIM School of Nutrition and Translational Research in Metabolism, Maastricht University Medical Centre+ (MUMC +), the Netherlands.

Greater kyphosis angles lead to increased loading on vertebral bodies in computational models. However, results about the relationship between severity of kyphosis and incident vertebral fracture (VF) risk have been conflicting. Therefore, the aim of this study was to evaluate associations between a) prevalent VFs and severity of kyphosis, and b) severity of kyphosis and incident VF risk, in smokers with or without COPD.

Department of Orthopaedic Surgery, School of Medicine, Pontificia, Universidad Catolica de Chile, Chile.

Background: There is insufficient knowledge of the epidemiology of Scheuermann's disease. The data available comes from estimations from young adults with obvious deformity, from studies evaluating children who may not have developed the deformity yet, or from older populations who can develop vertebral wedging secondary to other causes.

OBJECTIVE To investigate whether hemivertebra subtype as determined via CT was associated with breed and Cobb angle (a measure of the degree of spinal curvature) in apparently neurologically normal French Bulldogs, English Bulldogs, and Pugs. ANIMALS Client-owned French Bulldogs (n = 58), English Bulldogs (30), and Pugs (12) with thoracic hemivertebrae that underwent CT for reasons unrelated to spinal disease. PROCEDURES CT scans of each dog were evaluated, and hemivertebrae were categorized by subtype (ventral aplasia, ventral hypoplasia, lateral aplasia, lateral hypoplasia, ventrolateral aplasia, ventrolateral hypoplasia, ventral and median aplasia, ventral and median hypoplasia, and symmetric hypoplasia).

Spinal deformity and malocclusion association is not supported by high-quality studies: results from a systematic review of the literature.

Eur Spine J 2019 Jan 23. Epub 2019 Jan 23.

IRCCS Istituto Ortopedico Galeazzi, Milan, Italy.

Background: Several reports in the literature have suggested a causative association between oral occlusion and spinal deformity such as scoliosis and Scheuermann's disease or kyphosis. Based on these findings, a growing number of adolescents with spinal deformity receive orthodontic treatment, supposing a beneficial effect on the spine.

Objective: The aim of this study was to verify the association between spinal deformity and malocclusion in the orthopedic population and potential effect of orthodontic treatment on the spinal deformity. Read More

The Association Between the Classification of Early-onset Scoliosis and Smith Complications After Initiation of Growth-friendly Spine Surgery: A Preliminary Study.

J Pediatr Orthop 2019 Jan 19. Epub 2019 Jan 19.

Columbia University Medical Center, New York, NY.

Background: Early-onset scoliosis (EOS) is a complex, heterogeneous condition involving multiple etiologies, genetic associations, and treatment plans. In 2014, Williams and colleagues proposed a classification system of EOS (C-EOS) that categorizes patients by etiology, Cobb angle, and kyphosis. Shortly after, Smith and colleagues validated a classification system to report complications of growth-friendly spine instrumentation. Read More
