OBJECTIVE To retrospectively compare the clinical outcomes of anterior and posterior surgical treatment in single thoracolumbar-lumbar adolescent idiopathic scoliosis. METHODS Between January 2004 and August 2008, 22 female patients, averaged 14.5 years old (12 to 18 years), of thoracolumbar-lumbar adolescent idiopathic scoliosis were corrected by(More)
OBJECTIVE To design a clinically applicable transoralpharyngeal atlantoaxial reduction plate (TARP), introduce the operation procedure, and evaluate its preliminary clinical effects. METHODS A novel TARP system, including butterfly titanium alloy plate, self-locking screws, atlantoaxial reductor and other operational instruments was developed. This system(More)
OBJECTIVE To compare the short-term clinical outcome of non-fusion techniques using interspinous implantation Coflex(TM) and Wallis treatment in patients with lumbar spine degenerative diseases. METHODS Forty-one cases of lumbar stenosis, 18 of lumbar disc herniation, and 34 of lumbar stenosis with lumbar disc herniation were evaluated. Among the 43 cases(More)
OBJECTIVE To study relevant anatomical features of the structures involved in transoral atlanto-axial reduction plate (TARP) internal fixation through transoral approach for treating irreducible atlanto-axial dislocation and providing anatomical basis for the clinical application of TARP. METHODS Ten fresh craniocervical specimens were microsurgically(More)
OBJECTIVE To evaluate the short-term clinical results of a new approach of lumbar-pelvic fixation for lumbosacral reconstruction after resection of sacral tumors. METHODS Fifteen patients with sacral tumors underwent lumbar-pelvic fixation using TSRH-3D, CDH-M8 or ISOLA with iliac screws. The lumbosacral stability was evaluated according to the X-ray(More)
Patients that present with multiple primary malignant neoplasms are increasingly encountered, but the treatment of such patients presents specific challenges and long-term survival is rare. The present study reports the case of a 45-year-old female diagnosed with three rare, distinct primary malignant neoplasms, including epithelioid hemangioendothelioma(More)
OBJECTIVE To evaluate the synthetic typing and the treatment strategy for atlantoaxial dislocation. METHODS The synthetic typing of atlantoaxial dislocation was worked out on the base of pathogenesis typing, Fielding imaging typing, and clinical typing, named PIR typing system (Pathogenesis, Imaging, and Reduction). Ninety-three patients with atlantoaxial(More)
OBJECTIVE To design transoralpharyngeal atlantoaxial reduction plate (TARP), evaluate its biomechanical performance and observe its preliminary clinical effect. METHODS A brand-new TARP system was designed, including butterfly titanium alloy plate, self-locking screws, atlantoaxial reductor and other operation instruments. Twelve fresh occipital bone-C(3)(More)
