Design and Evaluation of Orthopedic Alignment Tools for Guidewire and Screw Insertion
Bibliographic record
Abstract
The Femoral Antegrade Starting Tool (FAST) was invented to facilitate guidewire alignment in femoral intramedullary nailing procedures. Previous cadaver studies demonstrated FAST’s potential to reduce surgical time and radiation exposure. This thesis continued the development of FAST through a first in human trial and expanded the guidewire insertion technology to be applicable to pelvic reconstruction procedures. The FAST design was enhanced for usability, manufacturability, assembly, sterilization and cleaning. A clinical pilot study to evaluate the tool’s safety and surgical workflow was planned and successfully executed (n=10). Expanding the technology to pelvic reconstruction included consultations with surgeons, substantial design changes, prototyping and simple usability studies. This resulted in the creation of two proof of concept prototypes. Initial surgeon feedback supports the potential of FAST and the pelvic guidewire/screw positioning tool. Further improvements to the FAST and pelvic tool workflows and designs are suggested towards ultimately bringing these technologies into clinical practice.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
