Osteoporosis is a condition which bone become fragile. Osteoporosis vertebrae bone causes fracture easily and also decreases fixation strength between pedicle screw implant and spine bone. Lack of fixation strength between pedicle screw implant and osteoporotic vertebrae bone lead to implant failure such as pedicle screw pull out. Therefore the purpose of this research is to develop intrapedicular locking screw concept of pedicle screw implant system which can resist pull out failure on osteoporotic bones. The main objective of this study is to know the possibility of intrapedicular locking screw for vertebral segments. The method of this study is by simulation of the position of intrapedicular locking screw design for each vertebral segment using Solidworks. Vertebral segments CT Scan sample is taken from one of the patients. After each pedicle screw is positioned correctly to the vertebral segments, pedicle screw position angle is measured. The result from measuring the position angle from pedicle screw it obtains the angle between 40°-70° for each vertebral segments sample. After this study is done, it concludes if the intrapedicular concept can be applied almost every vertebral segments.
