Function and Upright Time Following Limb Salvage, Amputation, and Rotationplasty for Pediatric Sarcoma of Bone
Bibliographic record
Abstract
We wished to determine the relative physical and psychosocial merits of limb-sparing reconstruction, above-knee amputation, and rotationplasty in survivors of childhood and adolescent lower extremity bone sarcoma. In comparing minimum 5-year disease-free survivors, we found that outcome was somewhat dependent on the measuring tool administered. A superior score of statistical significance on the system of evaluation of the Musculoskeletal Tumour Society and a trend toward higher Toronto Extremity Salvage Scores were found among patients with a limb-sparing reconstruction compared with those with an above-knee amputation. Short-Form 36 results and the amount of time spent in the upright position (uptime), as assessed with a remote activity monitor, were similar between these groups. Uptime was highest in patients who had undergone rotationplasty, although statistical assessment of this group was not feasible. Psychosocial outcome was similar between all groups. This information may be useful in discussing reconstruction with patients and their families.

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.
