The aim of this current study was to analyze the clinical outcomes after Discover cervical disc replacement and its effects on maintaining cervical lordosis and range of motion (ROM). The possible factors influencing postoperative ROM were analyzed. 27 men and 28 women with a mean age of 46.4 ± 8.7 years were prospectively followed up for 2 years. Clinical(More)
Anterior cervical decompression and fusion (ACDF) procedures are successful in treating multilevel cervical radiculopathy and cervical myelopathy. It was reported that this procedure would result in a loss of cervical range of motion. However, few studies have focused on the exact impact of multilevel (more than 3 levels) ACDF on cervical range of motion.(More)
Introduction Low back pain is one of the commonest chronic pain disorders affecting human health. Approximately 60%–95% of all people experience low back pain at some point during their lifetime. Lumbar disc herniation, a very prevalent disease of the spinal column, is responsible for most low back pain. In addition, lumbar disc herniation can also result(More)
The objective of this paper was to investigate the surgical strategy of the selection of the lowest instrumented vertebrae (LIV) in anterior correction for adolescent idiopathic scoliosis (AIS) and to discuss the relationship between the LIV and trunk balance. From 1998 to 2004, 28 patients with thoracolumbar/lumbar AIS (Lenke 5 type) were treated by(More)
OBJECT Multilevel anterior cervical decompression and fusion is indicated for patients with multilevel compression or stenosis of the spinal cord. Some have reported that this procedure would lead to a loss of cervical range of motion (CROM). However, few studies have demonstrated the exact impact of the procedure on CROM. Here, the authors describe short-(More)
OBJECTIVE To study the surgical indications, approaches and the clinical results of the total spondylectomy and instrumentation reconstruction in the treatment of cervical spinal tumor. METHODS From October 1998 to October 2003, 39 patients with lower cervical bone tumors, including 34 cases with primary tumor and 5 cases with metastatic tumor, were(More)
The objective of this study was to detect cerebral potentials elicited by proximal stimulation of the first sacral (S1) nerve root at the S1 dorsal foramen and to investigate latency and amplitude of the first cerebral potential. Tibial nerve SEP and S1 nerve root SEP were obtained from 20 healthy subjects and 5 patients with unilateral sciatic nerve or(More)
The survival of patients with hepatocellular carcinoma (HCC) has been improved with various diagnostic tools and treatment modalities. Consequently, spinal metastases from HCC are diagnosed more frequently. We investigated the clinical biomarkers of HCC patients presenting with spinal metastasis. Between January 2001 and December 2007, we recruited 30(More)
OBJECTIVE To investigate the way of resection of high-sacrum tumors and the way and duration of the spinal-pelvic TSRH or ISOLA internal fixation. METHOD From October 1998 through April 2002, 35 patients with sacral tumor were enrolled in our hospital, including 4 cases in L(5)-S(1), 2 in L(5)-S(2), 4 in S(1), 8 in S(1 - 2), 6 in S(1 - 3), 6 in S(1 - 4),(More)
