Abstract

fetched live from OpenAlex

BACKGROUND: The use of intramedullary devices for the management of intertrochanteric fractures has steadily increased without good evidence of their clinical efficacy. This prospective randomized multicenter study was designed to compare the clinical and radiographic outcomes of patients who had been treated with a traditional extramedullary hip screw for an unstable (AO/OTA 31-A2) intertrochanteric hip fracture with those of patients who had been treated with the newer intramedullary device for the same injury. METHODS: The Lower Extremity Measure (LEM) was used as the primary hip-specific outcome tool. The Functional Independence Measure (FIM), the timed "Up & Go" (TUG) test, as well as a timed two-minute walk test were used as secondary clinical outcome tools. Specific radiographic parameters were collected to assess for fracture movement, heterotopic ossification, and implant failure. RESULTS: No significant differences were noted between the intramedullary and extramedullary treatment arms with regard to either the primary or the secondary clinical outcome tools. The radiographic parameters favored the intramedullary treatment arm, which had less femoral neck shortening. CONCLUSIONS: While the use of the intramedullary devices led to better radiographic outcomes in this study, this did not translate to improved functional outcomes.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
