Primary spinal tumors are rare. Current knowledge on this subject is therefore limited due to the lack of study with large cohort. This study is prompted to share our data on clinical profiles of primary spinal tumors collected from a large series of patients. Clinical manifestations of 438 consecutive patients were summarized retrospectively with(More)
BACKGROUND Chordomas of the upper cervical spine are rare and present unique surgical challenge. This study aimed to describe the clinical characteristics and surgical management of patients with chordomas of the upper cervical spine. METHODS Twenty-one patients with chordomas of the upper cervical spine who were treated in Peking University Third(More)
STUDY DESIGN Case report. OBJECTIVE To describe a three-dimensional (3D) printed axial vertebral body used in upper cervical spine reconstruction after a C2 Ewing sarcoma resection in an adolescent boy. SUMMARY OF BACKGROUND DATA Ewing sarcoma is a malignant musculoskeletal neoplasm with a peak incidence in adolescents. Cervical spine as the primary(More)
BACKGROUND Herniated discs may exhibit calcification, and calcified discs may complicate surgical treatment. However, the osteogenic potential and expression of osteogenic markers in degenerative discs of different degenerative grades are still unclear. Our purposes are to study the differences in calcification rate and osteogenic potential of herniated(More)
BACKGROUND Aneurysmal bone cyst (ABC) is a benign lesion with the potential to be locally aggressive. The optimal treatment of cervical spine lesions remains controversial. This retrospective study was designed to evaluate the different treatments for primary ABCs of the cervical spine. METHODS This series included eight men and six women diagnosed(More)
OBJECTIVE The optimal surgical treatment for multilevel cervical spondylotic myelopathy (MCSM) remains controversial. This study compared the outcomes of three surgical approaches for MSCM treatment, focusing on the efficacy and safety of a combined approach. METHODS This retrospective study included 153 consecutive MCSM patients (100 men, 53 women; mean(More)
The recurrence rate of cervical chordomas is high, and hence it is important to discern the prognostic factors for local relapse and overall survival (OS). A retrospective review of 52 patients with cervical chordoma operated in our institution from January 1999 to March 2015 was performed. The association of clinicopathologic characteristics with local(More)
STUDY DESIGN A case report. OBJECTIVE To describe a new method called "cervical suspensory traction" and to report its effect in the treatment of severe cervical kyphotic deformity with neurofibromatosis-1 (NF-1) in a teenager. SUMMARY OF BACKGROUND DATA Cervical kyphotic deformity exceeding 100° due to NF-1 is a challenging surgical problem. Surgery(More)
CONTEXT Tumors involving the spine are associated with unique symptoms affecting both patient survival and health-related quality of life. Currently, there is no disease-specific instrument in Chinese to assess the symptom burden of these patients. OBJECTIVES The objective of this study was to translate and validate a Chinese version of the M.D. Anderson(More)
The purpose of this study was to detect the differentially expressed genes between ossified herniated discs and herniated discs without ossification. In addition, we sought to identify a few candidate genes and pathways by using bioinformatics analysis. We analyzed 6 samples each of ossified herniated discs (experimental group) and herniated discs without(More)
