Patellar Tendon-Bearing, Patten-Bottom Caliper Suspension Orthosis in Active Charcot Arthropathy: Crutch-Free Ambulation with No Weight Bearing in the Foot
Bibliographic record
Abstract
A custom, patellar-tendon bearing (PTB), patten-bottom, caliper suspension orthosis was constructed for six patients with severe, active (Eichenholtz stage I) Charcot arthropathy of the ankle and hindfoot. With the orthosis, the suspended foot and ankle remained completely non-weight-bearing, and the lower extremity supported full weight bearing along the posterior and anterior leg shells and PTB crest. Four of the six patients used the orthosis to ambulate without crutches, leaving the upper extremities free for functional use. Frequent adjustment of the orthosis and skin examination were required. Minor problems with the orthosis included superficial skin breakdown and downward pistoning of the leg associated with improper, loose donning. Patient compliance was poor in four of the six patients because of general debility, difficulty with balance, and discomfort. However, in the other two patients, the absence of mechanical forces on the foot and ankle in the orthosis allowed the swelling and erythema of the active phase of Charcot arthropathy to resolve within several weeks, with maintenance of functional ambulation during the months required for healing of the Charcot process.

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.
