ANALYSIS OF THE BIOMECHANICAL CHARACTERISTICS OF THE SPINAL INTERSPINOUS IMPLANTS 1Dae Kyung Choi, 1Yoon Hyuk Kim and 2Kyungsoo Kim 1University of Kyung Hee, Yongin, Gyeonggi, KOREA 2University of Kyonggi, Suwon, Gyeonggi, KOREA email: yoonhkim@khu.ac.kr INTRODUCTION (anterior longitude ligament (ALL), posterior longitude ligament (PLL), flaval ligament (FL), Spinal decompression surgery with spinal fusion is inter transverse ligament (ITL), inter spinal a widely used surgical procedure for the treatment ligament (ISL), supra spinal ligament (SSL), and of degenerative spine in the lumbar spine. However, capsular ligament (CL)). The information of it has been known that spinal decompression material properties and the attachment points of surgery causes the spinal instability. Some ligaments were taken from literatures [4,5]. cadaveric and finite element (FE) studies have reported that adjacent segment degeneration may In this study, biomechanical characteristics of reduce adverse effects on the adjacent levels Coflex (Paradigm Spine, Wurmlingen, Germany), resulting from fusion by maintaining physiologic Wallis (Abbott Laboratories, Bordeaux, France), ROM as well as pressure. Therefore the Viking (Sintea Plustek, Assago, Italy) and interspinous implants have been recently
