Non-Fusion Muscle-Sparing Technique to Treat Long-Segment Thoracolumbar Extradural Arachnoid Cyst in a Child: A Case Report and Review of the Literature.

World Neurosurg 2020 Jun 29. Epub 2020 Jun 29.

Department of Orthopedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand. Electronic address:

Introduction: Spinal extradural arachnoid cyst (SEAC) is an uncommon cause of spinal cord compression. It results from a small dural defect that leads to cerebrospinal fluid (CSF) accumulation in the cyst and subarachnoid space, and the cyst can compress the spinal cord and nerve roots. Surgery is the treatment of choice in symptomatic patients, and most cases have an immediately satisfying outcome after surgery. Read More

Two different types of postoperative sagittal imbalance after long instrumented fusion to the sacrum for degenerative sagittal imbalance.

J Neurosurg Spine 2020 Jun 26:1-10. Epub 2020 Jun 26.

3Department of Orthopedic Surgery, Kyung Hee University Hospital at Gangdong, Seoul, South Korea.

Spinopelvic sagittal balance: what does the radiologist need to know?

Radiol Bras 2020 May-Jun;53(3):175-184

Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP), Ribeirão Preto, SP, Brazil.

Sagittal balance describes the optimal alignment of the spine in the sagittal plane, resulting from the interaction between the spine and lower limbs, via the pelvis. Understanding sagittal balance has gained importance, especially in the last decade, because sagittal imbalance correlates directly with disability and pain. Diseases that alter that balance cause sagittal malalignment and may trigger compensatory mechanisms. Read More

Comparison of anterior and posterior approaches for treatment of traumatic cervical dislocation combined with spinal cord injury: Minimum 10-year follow-up.

Sci Rep 2020 Jun 25;10(1):10346. Epub 2020 Jun 25.

Operation-room, The First People' s Hospital of Lianyungang, Xuzhou Academy of Medical Sciences, Lianyungang, China.

Anterior reduction and interbody fusion fixation has not been compared directly with posterior reduction and short-segmental pedicle screw fixation for lower cervical dislocation, and so consensus is lacking as to which is the optimal method. The purpose of this paper is to compare long-term outcomes of the anterior versus posterior approach for traumatic cervical dislocation with spinal cord injury. One hundred and fifty-nine patients could be followed for more than 10 years (follow-up rate 84. Read More

Best practice guidelines for management of spinal disorders in skeletal dysplasia.

Orphanet J Rare Dis 2020 Jun 24;15(1):161. Epub 2020 Jun 24.

Victorian Clinical Genetics Services, Murdoch Children's Research Institute, University of Melbourne, Parkville, Victoria, Australia.

Background: Disorders of the spine present a common and difficult management concern in patients with skeletal dysplasia.

Objective: There is an increased recognition of disproportional lumbar lordosis (LL) and artificially high pelvic incidence (PI) as a cause for positive sagittal imbalance and spinal pelvic mismatch. For such cases, a sacral pedicle subtraction osteotomy (PSO) may be indicated, although its morbidity is not well described. In this study, the authors evaluate the specific complication risks associated with S1 PSO. Read More

Incidence and predictors of kyphotic deformity following resection of cervical intradural tumors in adults: a population-based cohort study.

Acta Neurochir (Wien) 2020 Jun 16. Epub 2020 Jun 16.

Department of Neurosurgery, Karolinska University Hospital, Elite Hotel Carolina, 4th floor, 171 76, Stockholm, Sweden.

Background: The first line of treatment for most cervical intradural tumors is surgical resection through laminotomy or laminectomy. This may cause a loss of posterior pulling force leading to kyphosis, which is associated with decreased functional outcome. However, the incidence and predictors of kyphosis in these patients are poorly understood. Read More

Department of Spine Surgery, Yantai Affiliated Hospital of Binzhou Medical University, No. 717, Jinbu Street, Yantai, 264000, Shandong, China.

Background: Anti-tuberculous therapy (ATT) alone cannot easily cure spine tuberculosis (STB) though it is the most essential treatment. Many studies have confirmed the efficacy of the surgical treatment of STB through anterior, anterolateral, posterior debridement, and intervertebral fusion or combined with internal fixation.

Post-Laminectomy Kyphosis in Achondroplasia Patients: To Concurrently Fuse or Not.

Cureus 2020 May 5;12(5):e7966. Epub 2020 May 5.

Neurosurgery, Penn State Milton S. Hershey Medical Center, Hershey, USA.

The purpose of this review is to look at the incidence of post-laminectomy kyphosis in achondroplasia patients and to determine whether skeletal maturity and the number and location of laminectomies predict kyphosis in this patient population. Our review of the literature included all articles from MEDLINE/PubMed and Ovid from inception to 2019. After removing duplicates and checking for relevancy, the final number of articles yielded was eight. Read More

To summarize the clinical manifestation and genetic characteristics of Chinese patients with achondroplasia (ACH) which is caused by pathogenic variants fibroblast growth factor receptor 3 (FGFR3) gene and establish the reference value of height centiles and height for age growth curve of patients for a more practical, simple and useful growth evaluation tool in China. Through a nationwide cross-sectional survey in China from July 2019 to January 2020 designed by Department of Pediatric Endocrinology and Genetics, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine, 210 subjects (110 boys, 100 girls), who harbored the pathogenic variant of FGFR3 gene and were diagnosed with achondroplasia, were recruited. The clinical and genetic data of enrolled subjects were collected and analyzed to explore the clinical genetic characteristics of Chinese ACH patients. Read More

Department of Physiotherapy, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran.

Background: Hyperkyphosis may cause balance impairment in elderly people. Although the effectiveness of orthoses for improving balance in hyperkyphotic elderly people has received much attention, the mechanisms by which devices affect balance remain unknown.

Objectives: The objective of this study was to evaluate changes in balance performance, thoracic kyphosis angle, craniovertebral angle, back muscle endurance and joint position sense after 3 months of wearing a Spinomed orthosis. Read More

J Neurosurg Spine 2020 Jun 5:1-8. Epub 2020 Jun 5.

1Department of Neurological Surgery, University of California, San Francisco, California; and.

Objective: A consequence of anterior cervical discectomy and fusion (ACDF) is graft subsidence, potentially leading to kyphosis, nonunion, foraminal stenosis, and recurrent pain. Bone density, as measured in Hounsfield units (HUs) on CT, may be associated with subsidence. The authors evaluated the association between HUs and subsidence rates after ACDF. Read More

The Effect of Spinopelvic Parameters on the Development of Proximal Junctional Kyphosis in Early Onset: Mean 4.5-Year Follow-up.

J Pediatr Orthop 2020 Jul;40(6):261-266

Division of Orthopaedic Surgery, IWK Health Centre, Halifax, NS.

Background: Proximal junctional kyphosis (PJK) is a major complication after posterior spinal surgery. It is diagnosed radiographically based on a proximal junctional angle (PJA) and clinically when proximal extension is required. We hypothesized that abnormal spinopelvic alignment will increase the risk of PJK in children with early-onset scoliosis (EOS). Read More
