PURPOSE The aim of the study was to explore surgical strategies for effectively treating spine fractures in patients with ankylosing spondylitis (AS) and investigate the postoperative outcomes. METHODS We retrospectively analyzed 9 patients with AS that was complicated by spine fractures, who underwent surgery at our spine and spinal cord clinic between 2005 and 2012. The surgical methods inc...

The aging of society has increased the number of cases of cervical spine disorder. Improved surgery, including cervical laminoplasty for posterior decompression, has resulted in favorable outcomes in many cases (Hirabayashi et al. 1981, Kurokawa et al.1983). Instrumentation such as pedicle screws used in lumbar surgery has also been developed for treatment of cervical deformities caused by agin...

As a result of rapid advances in the field of spinal instrumentation, the surgeon today has at his disposal many well-designed implants, such as pedicle screws, hooks, rods, plates, and interbody fusion devices. Many of these implants are modular and are used in combination, such as hooks and screws attached to rods, allowing the surgeon flexibility in selecting the appropriate implants to meet...

BACKGROUND Short-segment pedicle screw instrumentation (SSPI) is used for unstable burst fractures to correct deformity and stabilize the spine for fusion. However, pedicle screw loosening, pullout, or breakage often occurs due to the large moment applied during spine motion, leading to poor outcomes. The purpose of this study was to test the ability of a newly designed device, the Trans-Endpla...

To the Editor My original paper on the " Cortical Margining Capabilities of Fins 1 " has been made based on the data studied while I was working at the Cleveland Clinic Foundation as a research fellow. However, this article was submitted to two international journals by me and the co-author at the same time independently. I hereby retract the paper. 1. Jin BH, Kwon HD, Cho YE. Cortical marginin...
