In this case report, we present a 20-year old male’s clinical presentation of spinal cord compression. He presented with paraplegia, neurologic bladder, and bowel dysfunction. Spinal Magnetic Resonance Imaging (MRI) demonstrated 9th thoracic vertebra metastasis, and cord compression with edema. A chest computed tomography scan with contrast further revealed mediastinal and right infrahilar mass. Its histopathological features were consistent with Yolk Sac Tumor (YST). Further investigation using bone scintigraphy revealed spinal metastasis. This case represents a rare clinical presentation and disease manifestation of a metastatic extragonadal YST originating from the mediastinum and causing spinal cord compression in an adult male. Although it is rare, spinal cord compression should raise awareness and prompt evaluation for metastatic lesions given the rate of NSGCT metastasis and its associated poor prognosis.","PeriodicalId":89593,"journal":{"name":"Journal of spine","volume":"10 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70050146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explain the behaviour of the spine and its various components, biomechanical models are used where in-vivo studies are impractical. All biomechanical models of the spine share one common feature; each must contains an anatomical model of the spine and a way of distributing force to the components during this anatomical model. There's little consistency between previous anatomical models with authors incorporating different numbers of muscles, using different measures of muscle area (physiological cross-sectional area (PCSA) or cross-sectional area (CSA)), grouping muscles differently with reference to activation and using values between 30 N cm-2 and 100 N cm-2 for the utmost muscle force intensity. Most of those differences stem from a scarcity of detailed anatomical information for the muscles of the lumbar spine.","PeriodicalId":89593,"journal":{"name":"Journal of spine","volume":"10 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70050126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the increase in life expectancy, health care must be extended into maturity. The death of newborns with myelomeningocele had a substantial impact on survival rates prior to 1975. At least 75%–85% of children born with SB are projected to live to adulthood today. However, based on the current statistics, it is impossible to correctly predict the life expectancy of persons with SB. The expanding adult SB population has sparked a slew of research projects aimed at elucidating medical and rehabilitative concerns that affect this group. Neurological, neurosurgical, cognitive, psychosocial, renal/urological, bowel management, mobility, musculoskeletal/orthopaedic, sexual function, skin, and other domains are among them. Complications of the kidneys, heart, and lungs have all been identified as common causes of mortality. The medical and rehabilitation care of these secondary health disorders must be optimised in order to reduce mortality, morbidity, and impairment in adults with SB and improve quality of life.","PeriodicalId":89593,"journal":{"name":"Journal of spine","volume":"10 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70050835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to significant morbidity and complication rate, alternate graft materials have been investigated. This study seeks to determine the fusion rate of one such alternative, the K2M VESUVIUSTM Osteobiologic Fibers, a form of demineralized bone matrix. Methods: Prospectively collected CT scans of 27 patients with 29 instrumented levels were taken 1 year post-operatively. These were reviewed blindly by 5 fellowship trained spine surgeons to evaluate for fusion. The fusion mass was graded as no fusion (grade 1), partial unilateral (grade 2), partial bilateral (grade 3), solid unilateral (grade 4), or solid bilateral (grade 5). The fusion mass was then further classified as solid (grade 4-5), probable fusion (grade 3), or non-union (grade 1-2). The Kappa method was used to assess interrater reliability. We calculated the proportion of successful subjects at both cut-off values of either Grade 3 or Grade 4/5. Results: When using a cut-off grade of 3 or higher, 40% of subjects achieved fusion according to 4 of 5 graders and 50% achieved fusion according to 3 of the 5 graders. When using a cut-off grade of 4 or higher, 28% of subjects were found to achieve fusion by at least 4 graders and approximately 50% achieved fusion according to 3 of the graders. When analyzing correlation between the reviewers, 8 of 10 interrater reliabilities demonstrated moderate to good agreement. Correlation by grade showed that only grade 1 had significant agreement amongst the graders with a kappa value of 0.3394. Otherwise, the combined kappa value was 0.1092. Conclusion: Compared to the literature control using iliac crest bone autograft of 70.6% fusion rate, the results with K2M VESUVIUSTM Osteobiologic Fibers DBM were disappointing regardless of the cut off used.","PeriodicalId":89593,"journal":{"name":"Journal of spine","volume":"10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70050975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
