BACKGROUND There is considerable controversy as to which posterior technique is best for the treatment of multi-level cervical spondylotic myelopathy. The aim of this study was to compare the clinical and radiographic results and complications of laminoplasty (LAMP) and laminectomy (LAMT) in the treatment of multi-level cervical spondylotic myelopathy.

Hypertrophy of ligamentum flavum (LF) contributes to lumbar spinal stenosis (LSS) and is caused mainly by fibrosis. Recent data indicate that miR-155 plays a crucial role in the pathogenesis of different fibrotic diseases. This study aimed to test the hypothesis that miR-155 exerts effects on LF thickness by regulating collagen expression. We found that LF(More)
PURPOSE A successful osseointegration relies on the interplay of implant surface and surrounding bone marrow cells. This study was undertaken to investigate the impact of age and gender on the bone marrow composition. METHODS Bone marrow aspirates were obtained from the discarded metaphysis region of the femoral head in 24 patients with total hip(More)
OBJECTIVE To analyze perioperetive clinical features and outcomes of surgical treatment for cervical spondylotic myelopathy (CSM) in elderly patients. METHODS From 2006 to 2013, we retrospectively reviewed 136 patients with CSM who underwent surgery. The patients were divided into two groups: 70 years or older (elderly group, 58 patients) and younger than(More)
BACKGROUND The aim of this study was to compare the therapeutic effects of anterior 'skip' corpectomy with posterior decompression for treating four-level cervical spondylotic myelopathy. METHODS Operation time and blood loss during the operation for the anterior and posterior approach groups were recorded. Patients were examined with cervical lateral(More)
The goal in the treatment of osteonecrosis of the femoral head is to preserve, not replace, the femoral head. Although many methods have been proposed, none has proved completely satisfactory. Cellular mediators as a supplement to bone grafting and decompression is an attractive approach to this problem because it combines the desirable features of other(More)
OBJECTIVE To assess whether polymorphisms of the fat mass and obesity associated gene (FTO) are associated with the presence and severity of degenerative disc disease (DDD) in a Chinese Han population. METHODS In this case-control study, patients with DDD and controls matched for age, sex and body mass index were genotyped for six single nucleotide(More)
STUDY DESIGN A multicenter cross-cultural study to re-evaluate the reliability and validity of the simplified Chinese version of Scoliosis Research Society-22 (SRS-22) Patient Questionnaire. OBJECTIVE To assess the concurrent validity and reliability of this instrument in mainland China. SUMMARY OF BACKGROUND DATA The SRS-22 Questionnaire was developed(More)
BACKGROUND Anterior cervical plate had developed continuously, and this study aimed to assess the biomechanics of a novel self-locking plate system for anterior cervical fixation designed by ourselves. METHODS Twelve anterior cervical plates (i.e., six novel plates and six DePuy plates) were subjected to a pull-out test and a fatigue test. In addition, 12(More)
BACKGROUND Split spinal cord malformation (SSCM) is rare in scoliosis. This study evaluated the safety and effectiveness of one-stage surgical treatment of congenital scoliosis (CS) in patients with SSCM in a single Chinese center. METHOD A retrospective study of 5 cases who underwent surgery for CS with SSCM (2 type I and 3 type II) from March 2004 to(More)
