ABSTRACT
At present, there are still some problems in the standardized residency training. Some standardized training bases often regard the resident trainees as ordinary practitioners, and devote their time and energy to the daily medical procedural work without giving enough training and teaching, ignoring the basic skills training of resident trainees. Therefore, this study constructed an active knowledge push system based on business scenarios. The system mainly includes three parts: sensitive operation identification layer, knowledge index layer and resource push layer in order to cultivate the norms of diagnosis and treatment of standardized training students and reasonably solve the problem of inconvenient resource acquisition in clinical work. Through the preliminary application, it was found that the system has effectively improved the mini-clinical evaluation exercise (Mini-CEX) score of the trainees and achieved good results.
ABSTRACT
BACKGROUND: Minimally invasive percutaneous pedicle screw fixation possesses the advantages of less blood loss, less muscle and soft tissue dissection, and rapid recovery; however, accuracy of the screw positioning is the key to be successful.OBJECTIVE: To explore the application value of self-designed spinal localizer in the screw positioning for minimally invasive percutaneous pedicle screw fixation.METHODS: 428 patients with thoracolumber disorders were subjected to minimally invasive percutaneous pedicle screw fixation at the First Affiliated Hospital of University of South China, from March 2009 to March 2015, and randomly underwent the preoperative screw positioning by self-designed spinal localizer or one of traditional localizing methods (iliac crest, ribs, symptomatic vertebral appearance, skin marker, Kirscher wire, puncture needle localizations). The location accuracy, positioning time and radiographic times were compared among methods.RESULTS AND CONCLUSION: (1) Compared with the traditional localization methods, the self-designed spinal localizer was superior in accurate rate (P < 0.05), cost less positioning time (P < 0.05) and received less radiation (P < 0.05). (2) To conclude, the self-designed localizer exhibits a certain application value, which is an ideal method in preoperative localization for minimally invasive percutaneous pedicle screw fixation.
