STUDY DESIGN Retrospective, comparative study. OBJECTIVE To compare the effects of anterior rod-screw instrumentation and posterior pedicle screw instrumentation on sagittal balance in patients with Lenke type 5 adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Lenke type 5 AIS is treated by anterior or posterior spinal fusion surgery.(More)
MD5 Crypt is a cryptographic algorithm used commonly in UNIX system for authentication. By using the additional randomization of the salt and complexity of the scheme, it makes the traditional password cracking techniques invalid on common computing systems and the security of the system is guaranteed. Benefited from the thriving of petaflops heterogeneous(More)
STUDY DESIGN A retrospective study. OBJECTIVE The aim of this study was to compare clinical and radiological outcomes of anterior cervical corpectomy and fusion (ACCF) combined with artificial disc replacement (C-ADR) and ACCF combined with anterior cervical discectomy and fusion (ACDF) in patients with consecutive 3-level cervical spondylotic myelopathy(More)
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To review the literature systematically and make a comprehensive understanding of the efficacy of these 2 drugs in the management of postoperative pain after lumbar spinal surgery. SUMMARY OF BACKGROUND DATA Several trials that evaluated the efficacy of gabapentin and pregabalin in the(More)
Between March 2003 and September 2007, 170 consecutive patients with lumbar degenerative disease were studied retrospectively. Eighty patients underwent posterior lumbar interbody fusion (PLIF group) with pedicle screw (PS) fixation, and 82 patients underwent posterolateral fusion (PLF group) with PS fixation. Eight patients were lost to follow-up. The(More)
STUDY DESIGN A retrospective radiographic study. OBJECTIVE To investigate which preoperative radiographic parameters best correlate with the angulation and translation of the lowest instrumented vertebra (LIV) and global coronal balance after posterior spinal pedicle screw fixation for thoracolumbar/lumbar (TL/L) adolescent idiopathic scoliosis. SUMMARY(More)
We postulated that the lowest instrumented vertebra (LIV) can be determined based on the apical vertebra. Seventy-two Lenke type 1 patients (average age: 13.6 years) receiving posterior spinal fusion were randomised into two groups. In group A, the apical vertebra was used to determine the LIV and in group B the neutral vertebra was used. All patients had(More)
AIMS This study aims to investigate the effect of allicin on motor functions and histopathologic changes after spinal cord injury and the mechanism underlying its neuroprotective effects. MAIN METHODS The motor function of rats was evaluated with the Basso, Beattie, and Bresna test. Histopathologic changes were evaluated by hematoxylin and eosin and Nissl(More)
BACKGROUND Transverse patella fractures are the most common type of patella fractures. Minimally invasive surgical technique for treatment of transverse patella fractures with the Cable Pin System has not been previously reported. METHODS Thirty-four patients with displaced transverse fractures of the patella were included in this prospective study and(More)
PURPOSE To assess and characterize the sacrum angular displacements in response to lumbar lordosis after lumbar/lumbosacral fusion. METHODS A finite element model of the lower lumbar spine-pelvis was established and used to simulate the posterior fusion at L3-L5 and L4-S1. The lordosis angle in the fusion segments was set to five different conditions with(More)
