This module allows medical officers, junior orthopedic surgery residents, and surgeons who are not orthopedic specialists to become confident and competent in irrigation and debridement, powered and manual drilling, positioning and correctly inserting Schanz screws, and constructing the uniplanar external fixator frame as part of external fixation procedures for open tibial shaft fractures performed in regions without specialist coverage. To maximize patient safety, this module teaches learners to use a powered drill to insert self-drilling Schanz screws through the near cortex and then manually advance Schanz screws into the far cortex to avoid plunging.
It's highly recommended to: (i) print off this checklist and review it before simulation skills training, (ii) have an assistant read out and complete this checklist to verify that all the steps are properly performed during the simulation skills training, and (iii) file and save a back-up copy of the completed and signed checklist for your training records.
