The cortical bone trajectory(CBT) is a novel technique in lumbar fixation and *** unique caudocephalad and medial-lateral screw trajectories endow it with excellent screw purchase for vertebral fixation via a minimally invasive *** combined use of CBT screws with transforaminal or posterior lumbar interbody fusion can treat a variety of lumbar diseases,including spondylolisthesis or stenosis,and can also be used as a remedy for revision surgery when the pedicle screw *** has obvious advantages in terms of surgical trauma,postoperative recovery,prevention and treatment of adjacent vertebral disease,and the surgical treatment of obese and osteoporosis ***,the concept of CBT internal fixation technology appeared relatively recently;consequently,there are few relevant clinical studies,and the long-term clinical efficacy and related complications have not been ***,large sample and prospective studies are needed to further reveal the long-term complications and fusion *** a supplement to the traditional pedicle trajectory fixation technique,the CBT technique is a good choice for the treatment of lumbar diseases with accurate screw placement and strict indications and is thus deserving of clinical recommendation.

With the utilization of computer technology and network technology in building network teaching system approaching perfection, PBL teaching model is gradually applied to network teaching. On the basis of PBL teaching theory, this paper proposes a network teaching system based on PBL via network teaching model, using C/S structure and Java language to develop the prototype model and adding multi-agent application level to C/S structure in system designing in order to meet the requirements of the utilization of PBL method in network teaching. This new system successfully implements the innovative application of a problem-based network teaching.
