Spontaneous herniation of the spinal cord is a rare disease entity in which spinal cord substance is herniated through a previously uninjured and/or untouched dura. It is a cause of myelopathy that is treatable but difficult to diagnose. We report the CT and MR findings of a case of spontaneous thoracic spinal cord herniation manifesting as ventrolateral protrusion of thoracic spinal cord through a dural defect.

Investigation into 2771 pupils (1338 boys and 1433 girls) in 4 grade class groups (1, 5, 9,and 12) at districts of Hai Ba Trung, Cau Giay, Soc Son, Gia Lam of Ha Noi City from October to December 2004. Grade 1 class group included 623 pupils, grade 2 class group included 713 pupils, grade 9 class group included 695 pupils and grade 12 class group included 740 pupils. Rate of soliosis in these pupils was 18.91%. The highest rate of soliosis was in grade 9 class group (22.16%), the lowest rate in grade 1 class group (16.37%). The highest rate of soliosis was in Hai Ba Trung district, the lowest rate in Gia Lam district

On occasion of a hydrosyringomyelie accompanied with communicating hydrocephalus which was managed successfully and literature referred, the authors had some remarks about management of this disease. Some remarks of such as: the disease often appears in one region, most in cervical and upper thoracic of the spinal canal. It is the rare disease caused by many sources. It may be congenital approximately 50-70% of CHIARI I (Menezes) and 40-95% of CHIAR II (Naidich). It may be also secondary to spinal trauma, myelitis (virus, bacteria, tuber culosis bacillus...vv.) Signals and symptoms are poorly. The diagnosis is difficulty but no longer now because of applying MRI. Since this disease is accompanied with others malformations, the management have some differences, depending on the caused of the disease

A fracture of the posterior arch of the atlas is a rare complication of Halifax clamp fixation for atlantoaxial fusion. To the best of our knowledge, there is only one case reported reporting the English literature. Revision for this condition is challenging because of the difficulty in the surgical approach, internal fixation, and fusion. We report a case of bilateral fractures and nonunion of the posterior arch of the atlas and atlantoaxial nonunion after an atlantoaxial fusion procedure using Halifax clamp fixation, which resulted in persistent atlantoaxial instability and progressive myelopathy. Segmental screw fixation was performed using C1 lateral mass screws and C2 subarticular screws, along with intraarticular and extraarticular atlantoaxial inter-facet fusion.

Objectives: Traditionally, scoliosis surgery is aimed at attaining a fused, balanced and painless spine. With improvement in surgical and instrumentation techniques, spine surgeons strive to achieve higher degree of Cobb’s angle and rib hump correction with the idea of greater patient satisfaction. The aim of this study was to determine the patients’ satisfaction using SRS-22 questionnaire and their correlations with the radiographic changes. Materials and methods: A prospective study was conducted in a tertiary referral centre using the Scoliosis Research Society-22 (SRS-22) questionnaire during the patients’ annual follow up, between February to April 2014. Thirtyseven patients who met the inclusion criteria were enrolled. Results: The mean pre-operative Cobb’s angles were 57.8o ± 12.7o and mean post-operative angle of 20.0o ± 10.4o, resulting in average correction of 65.9 ± 14.4%. Mean preoperative rib hump was 61.1 ± 15.4 mm with mean postoperative rib hump of 15.8 ± 17.8 mm, resulting in average reduction of 77.7 ± 23.7%. Mean of post-operative total SRS score was 4.1 ± 0.5. Using Spearman rank correlation, the percentage of Cobb’s angle correction versus the SRS-22 score showed correlation of 0.17 (P=0.33) while the percentage of rib hump reduction versus SRS-22 score showed a correlation of 0.11 (P=0.53). Conclusion: In this study, the average total SRS-22 score was 4.1 ± 0.5 (range, 3.1-4.9) post-operatively indicating very high satisfaction rate overall. Despite attempts at greater curve correction and rib hump reduction, there is no direct correlation between patient satisfaction and radiographic parameters.

Background & Objectives: Multiple sclerosis (MS), neuromyelitis optica (NMO) and acute transverse myelitis (ATM) are common diseases in neurology; however their corresponding cervical spinal cord involvements are still ambiguous. The purpose of this study was to demonstrate the utility of diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) in identifying the injury in cervical spinal cord. Methods: Nine patients and nine healthy volunteers were enrolled in this study. Conventional sequences and DTI scan were performed on each participant. Results: The average fractional anisotrophy (FA) values of the cervical cord in patients with acute cerebral type MS, acute or stationary cerebrospinal type MS, acute NMO, or acute ATM were all significantly decreased relative to the control group (p <0.05). As to the cerebrospinal type MS, the changes in acute-stage patients were more apparent (p <0.05). The average FA value of the cervical cord in acute NMO was decreased more extensively, involving the normal-appearing spinal cord (p <0.05). In patients with MS or NMO, The lesions showed significantly hypointense on FA images and directionally encoded color (DEC) images, nevertheless the pathological areas on DTI images were no significantly different from those on routine sequences. On DTT, the fiber tracts in the lesion-involved regions were all sparser than that in control regions, nevertheless interruption or impairment of fiber tracts could only be noted in NMO patients. Bilateral differences of average FA values in the cervical cord was noted in one case with ATM and another case with MS (p <0.05), and the decrease of FA values was significant in the main side of clinical presentations. Conclusion: DTI and DTT may be a sensitive measure for early cervical injury in MS, NMO and ATM
