The authors report the study of a series of 23 partial isthmic lyses which occurred in a young population (15 cases) and in an adult one (8 cases) between 1983 and 1988, in the form of persistent lumbosacral pains. The initial radiological signs, the key to an early diagnosis, are defined: cortical notches more often regarding the lower cortex than the upper one, incomplete fissures reaching the two cortical poles, gradual narrowing of the isthmus. The value of standard radiography is underlined, with the oblique incidences close to the profile regularly ensuring the diagnosis, with the exception of 4 cases out of 23 for which tomography was required. As regards the evolution, the value of the diagnosis of the initial lesions is recalled, giving the hope of a restoration of the posterior inter-articular fractures by a rigid setting (4 months on average). This ability to reconstruct the lumbar isthmus is observed in the young subjects (10 out of 13 immobilizations) but also in the adult subjects (3 reconstructions for 5 immobilizations carried out). These results enable the early detection of prelytic states, in order to administer an suitable treatment resting on the rigid setting of the lumbosacral region, re-education and the control of the risk factors.

Study Design: A modified Delphi study.
Purpose: This study sought to establish expert consensus on the use of cortical bone trajectory (CBT) for lumbar pedicle screws.
Overview Of Literature: The CBT technique is widely used in the treatment of various degenerative lumbar diseases because it reduces surgical time, soft tissue exposure, and blood loss; improves biomechanical stability; and allows for faster patient recovery.

Background: Transpedicular fixation depends on accuracy of the entry points, angle of insertion and pedicular isthmus width for adequate screw insertion. Preoperative measurements of pedicle dimensions reduce the chances of failure during insertion. These pedicle dimensions (transverse diameter, longitudinal diameter, and maximum length of purchase [MLP]) vary with sex and race.

Objective: The cortical bone trajectory (CBT) technology is an effective substitute for traditional pedicle screw (PS) technology. However, there is still controversy about the CBT screw technology placement strategy. The objective of this study was to simulate cortical screw placement with the help of three-dimensional (3D) software, to discuss the differences in screws between genders and vertebral segments, and to explore a safer and more efficient strategy for cortical screw placement.
