Review Case Reports
Giant chordoma in the thoracolumbar spine: a case report and literature review.
Case report. ⋯ Primary chordoma in the thoracolumbar spine is extremely rare. The treatment is difficult because the current literature is sparse and patients are rare. Complete resection and internal fixation are effective for reducing recurrences and metastasis.

The objective of this study was to analyze the interobserver reliability and intraobserver reproducibility of the new AOSpine thoracolumbar spine injury classification system in young Chinese orthopedic surgeons with different levels of experience in spinal trauma. Previous reports suggest that the new AOSpine thoracolumbar spine injury classification system demonstrates acceptable interobserver reliability and intraobserver reproducibility. However, there are few studies in Asia, especially in China. ⋯ This study suggests that the new AO spine injury classification system may be applied in day-to-day clinical practice in China following extensive training of healthcare providers. Further prospective studies in different healthcare providers and clinical settings are essential for validation of this classification system and to assess its utility.

The aim of this multicentre study was to determine whether the recently introduced AOSpine Classification and Injury Severity System has better interrater and intrarater reliability than the already existing Thoracolumbar Injury Classification and Severity Score (TLICS) for thoracolumbar spine injuries. ⋯ Recently proposed AOSpine classification has better reliability for identifying fracture morphology than the existing TLICS. Additional studies are clearly necessary concerning the application of these classification systems across multiple physicians at different level of training and trauma centers to evaluate not only their reliability and reproducibility, but also the other attributes, especially the clinical significance of a good classification system.

Review Case Reports
A case report of atypical long segmental thoracic hypertrophic pachymeningitis with ossification of ligamentum flavum and literature review.
Thoracic spinal stenosis caused by ossification of ligamentum flavum (OLF) is frequently seen, but long segmental thoracic spinal cord compressed by consequent thickened ligament posteriorly was rarely reported. ⋯ HP is a rare condition characterized as thickening and enhancement of the dura mater on contrast-enhanced MRI and chronic inflammatory hyperplasia changes on biopsy. A case of atypical HP complicated with OLF is described. Chondrocytes infiltration in histological examination indicates the potential of ossification in HP.

Case Reports
Long-term survival case of malignant glomus tumor mimicking "dumbbell-shaped" neurogenic tumor.
We report a very rare case of long-term survival case of malignant glomus tumor (MGT) without widespread metastasis. ⋯ This is the first case report of MGT which lesions at two time points were confirmed to have common histological features and which confirmed the long-term survival over a 40-year period.
