a survey on cortical bone trajectory for spinal fusions
there have been a number of developments in screw design and implantation techniques over recent years, including proposal of an alternative trajectory entitled as cortical bone trajectory (cbt). cortical bone trajectory has been investigated in recent medical treatments as an alternative for screw fixation aimed at increasing purchase of pedicle screws in higher density bone. cbt screw inserti...
متن کاملShould we use cortical bone screws for cortical bone trajectory?
OBJECT In 2009, Santoni et al. reported cortical bone trajectory (CBT) as a method of inserting pedicle screws to obtain more solid fixation, and proposed the use of cortical trajectory screws with a more closely placed thread (cortical screws) for CBT. Since the entry trajectory in CBT differs from that in the traditional trajectory, it is unclear whether the increased strength derives from th...
متن کاملChondrosarcoma of the petrous bone: a challenging clinical entity
Skull base chondrosarcomas are challenging lesions to treat. In this manuscript, we present a brief overview about this clinical entity. Furthermore, we present an illustrated case with chondrosarcoma of the petrous bone and highlight microsurgical treatment options. Introduction Skull base tumours are challenging, and neurosurgeons and ENT specialists probably find these lesions the most diffi...
متن کاملCortical and Trabecular Bone
During the normal growth and development of man and animals the bones grow in length and width and undergo progressive changes in their architecture, a process known as maturation. These normal processes are governed by numerous and complex forces but one of them, the plane of nutrition during the growing period, is of major importance. Undernourished children are small in stature and have bone...
متن کاملCortical Bone Fracture
The structural integrity of ‘‘hard’’ mineralized tissues such as bone is of great importance, especially because bone is the primary structural component of the body, serving as a protective load-bearing skeletal framework. As a structural material, bone is unique when compared with other engineering materials because of its wellknown capacity for self-repair and adaptation to changes in mechan...
